Stress-Only Adenosine CMR Improves Diagnostic Yield in Stable Symptomatic Patients With Coronary Artery Calcium.

OBJECTIVES: This study assessed whether adenosine stress-only perfusion cardiac magnetic resonance (CMR) following a positive coronary artery calcium (CAC) score improved the diagnostic yield of invasive coronary angiography (CAG) in patients with stable chest pain. The study also established the association between positive CAC scores and stress-induced myocardial ischemia. BACKGROUND: The diagnostic yield of catheterization among patients with suspected coronary artery disease (CAD) is low. Improved patient selection and diagnostic testing are necessary. The CAC score can minimize unnecessary diagnostic testing, and in low-risk patients, normal CMR results have a high negative predictive value. Less comprehensive protocols may be sufficient to guide further work-up. METHODS: A total of 642 consecutive patients (mean age: 63 years; 50% women) with stable chest pain and CAC scores of >0 who were referred for CMR were enrolled. Patients with a perfusion defect were subsequently examined by CAG. Patients were followed up for 1 year. Outcome was obstructive CAD. RESULTS: Obstructive CAD was present in 12% of patients. For CAD diagnosis, the sensitivity of adenosine CMR was 90.9% (95% confidence interval [CI]: 88.7 to 93.1), specificity was 98.7% (95% CI: 97.9 to 99.6), positive predictive value was 92.0% (95% CI: 89.8 to 94.1), and negative predictive value was 98.6% (95% CI: 97.6 to 99.5). A CAC score between 0.1 and 100 without typical angina was associated with obstructive CAD in only 3% of patients. Patients with nonanginal chest pain and a CAC score ≥400 had obstructive CAD (16%). CONCLUSIONS: Stress-only adenosine CMR had high diagnostic accuracy and served as an efficient gatekeeper to CAG in stable patients with a CAC score >0. Patients with CAC scores between 0.1 and 100 could be deferred from further testing in the absence of clinical features that suggested high risk. However, in patients with CAC score ≥400, functional testing should be indicated, regardless of the type of chest pain.

Two decades after coronary radiation therapy: A single center longitudinal clinical study.

OBJECTIVES: The aim of this study was to evaluate the very long-term clinical outcome after radioactive stent (RS) implantation and intracoronary ß radiation brachytherapy (IRBT). BACKGROUND: Radioactive stents (RS) and intracoronary ß radiation brachytherapy (IRBT) were introduced to prevent restenosis after percutaneous coronary intervention (PCI). Both techniques were associated with a higher incidence of major adverse cardiac events (MACE) in the short and intermediate-term follow up as compared to conventional PCI. METHODS: One hundred and thirty-three patients received radioactive stents (32 P) and 301 patients were treated with IRBT adjunctive to PCI. These groups were propensity matched to respectively 266 and 602 control patients who were treated with routine PCI during the same inclusion period. Endpoints were all-cause mortality and MACE, defined as all-cause death, any myocardial infarction or any revascularization. RESULTS: Median follow-up duration was 17 years. All-cause mortality rates were similar in all groups. Adjusted hazard ratios for MACE and mortality in the RS cohort were 1.55 (95% CI 1.20-2.00) and 0.92 (95% CI 0.63-1.34), respectively. Adjusted hazard ratios for MACE and all-cause mortality in the IRBT cohort were 1.41 (95% CI 1.18-1.67) and 0.95 (95% CI 0.74-1.21), respectively. The difference in MACE rates was predominantly driven by coronary revascularizations in both groups, with a higher MI rate in the IRBT group as well. CONCLUSIONS: Coronary radiation therapy was associated with early increased MACE rates, but the difference in MACE rates decreased beyond 2 years, resulting in a comparable long-term clinical outcome. Importantly, no excess in mortality was observed.

Life-long clinical outcome after the first myocardial revascularization procedures: 40-year follow-up after coronary artery bypass grafting and percutaneous coronary intervention in Rotterdam.

OBJECTIVES: Our goal was to evaluate the outcomes of the first patients treated by venous coronary artery bypass grafting (CABG) or percutaneous coronary interventions (PCIs) with balloon angioplasty at a single centre who have reached up to 40 years of life-long follow-up. METHODS: We analysed the outcomes of the first consecutive patients who underwent (venous) CABG (n = 1041) from 1971 to 1980 and PCI (n = 856) with balloon angioplasty between 1980 and 1985. Follow-up was successfully achieved in 98% of patients (median 39 years, range 36-46) who underwent CABG and in 97% (median 33 years, range 32-36) of patients who had PCI. RESULTS: The median age was 53 years in the CABG cohort and 57 years in the PCI cohort. A total of 82% of patients in the CABG group and 37% of those in the PCI group had multivessel coronary artery disease. The cumulative survival rates at 10, 20, 30 and 40 years were 77%, 39%, 14% and 4% after CABG, respectively, and at 10, 20, 30 and 35 years after PCI were 78%, 47%, 21% and 12%, respectively. The estimated life expectancy after CABG was 18 and 17 years after the PCI procedures. Repeat revascularization was performed in 36% and 57% of the patients in the CABG and PCI cohorts, respectively. CONCLUSIONS: This unique life-long follow-up analysis demonstrates that both CABG and PCI were excellent treatment options immediately after their introduction as the standard of care. These procedures were lifesaving, thereby indirectly enabling patients to be treated with newly developed methods and medical therapies during the follow-up years.

Heart Team decision making and long-term outcomes for 1000 consecutive cases of coronary artery disease.

OBJECTIVES: The Heart Team has been recommended as standard care for patients with coronary artery disease (CAD). However, little is known about the real benefits, potential treatment delays and late outcomes of this approach. Our goal was to determine the safety and feasibility of multidisciplinary Heart Team decision making for patients with CAD. METHODS: We retrospectively assessed 1000 consecutive cases discussed by the Heart Team between November 2010 and January 2012. We assessed (i) time intervals between different care steps involving the Heart Team; (ii) the distribution of patients according to the complexity of their CAD; and (iii) the 5-year survival as estimated from Kaplan-Meier curves. RESULTS: Of 1000 case discussions, 40 were repeat cases, resulting in 960 unique cases. The mean age was 65 years, 73% were men, and 29% had diabetes. Native vessel disease was present in 86.4%, of which 69% had simple 1-vessel disease (1VD) or 2-vessel disease (2VD), and 31% had complex left main (LM) or 3-vessel disease (3VD). The time interval between referral by a community hospital and final treatment was less than 6 weeks for 90% of cases. Treatment decisions were delayed in 35% of cases due to a need for additional diagnostic information. For simple 1- or 2VD with or without proximal left anterior descending artery involvement, treatment was medical therapy in 6% and 12%, respectively; percutaneous coronary intervention (PCI) in 88% and 85%, respectively; and coronary artery bypass grafting (CABG) in 6% and 3%, respectively. For 3VD disease, treatment was equally split between CABG and PCI (46% for both). PCI was preferred for isolated LM or LM with 1VD (81% vs CABG 16%), whereas CABG was preferred in LM with 2- or 3VD (71% vs PCI 19%). The 5-year mortality rate was 16% for 1- or 2VD, 17% for 3VD, 3% for isolated LM or with 1VD and 27% for LM with 2- or 3VD. CONCLUSIONS: In this single-centre analysis, the Heart Team approach was feasible, with decision making and treatment by the Heart Team following within a short time after referral. However, the timing of treatment could be further optimized if adequate information and imaging were available at the time of the Heart Team meeting. The final treatment recommendation by the Heart Team was largely in accordance with clinical guidelines.

Impact of device-host interaction on paravalvular aortic regurgitation with different transcatheter heart valves.

AIMS: We sought to evaluate the interaction of different aortic root phenotypes with self-expanding (SEV), balloon-expandable (BEV) and mechanically expanded (MEV) and the impact on significant aortic regurgitation. METHODS AND RESULTS: We included 392 patients with a SEV (N = 205), BEV (N = 107) or MEV (N = 80). Aortic annulus eccentricity index and calcification were measured by multi-slice CT scan. Paravalvular aortic regurgitation was assessed by contrast aortography (primary analysis) and transthoracic echocardiography (secondary analysis). In mildly calcified roots paravalvular regurgitation incidence was similar for all transcatheter heart valves (SEV 8.4%; BEV 9.1%; MEV 2.0% p = 0.27). Conversely, in heavily calcified roots paravalvular regurgitation incidence was significantly higher with SEV (SEV 45.9%; BEV 0.0%; MEV 0.0% p < 0.001). When paravalvular regurgitation was assessed by TTE, the overall findings were similar although elliptic aortic roots were associated with more paravalvular regurgitation with SEV (20.5% vs. BEV 4.5% vs. MEV 3.2%; p = 0.009). CONCLUSIONS: In heavily calcified aortic roots, significant paravalvular aortic regurgitation is more frequent with SEV than with BEV or MEV, but similar in mildly calcified ones. These findings may support patient-tailored transcatheter heart valve selection. CLASSIFICATIONS: Aortic stenosis; multislice computed tomography; transcatheter aortic valve replacement; paravalvular aortic regurgitation. CONDENSED ABSTRACT: We sought to evaluate the interaction of different aortic root phenotypes with self-expanding (SEV), balloon-expandable (BEV) and mechanically expanded (MEV) and the impact on significant aortic regurgitation. We included 392 patients with a SEV (N = 205), BEV (N = 107) or MEV (N = 80). Aortic annulus eccentricity index and calcification were measured by multi-slice CT scan. Paravalvular aortic regurgitation was assessed by contrast aortography and transthoracic echocardiography. We found that in heavily calcified aortic roots, significant paravalvular aortic regurgitation is more frequent with SEV than with BEV or MEV, but similar in mildly calcified ones.

Procedural and long-term outcome after catheter ablation of idiopathic outflow tract ventricular arrhythmias: comparing manual, contact force, and magnetic navigated ablation.

Aims: Currently, comparative data on procedural and long-term clinical outcome of outflow tract (OT) idiopathic ventricular arrhythmia (IVA) ablation with manual (MAN), contact force (CF), and magnetic navigation system (MNS) ablation are lacking. The aim of this study was to compare the procedural and long-term clinical outcome of MAN, CF, and MNS ablation of OT IVAs. Methods and results: Seventy-three patients (31 MAN, 17 CF, and 25 MNS patients; consecutive per group) with OT IVA, who underwent catheter ablation in our centre were analysed. Procedural success rates (success at the end of the procedure), procedural data and long-term follow-up data were compared. Baseline patient demographics were comparable. Procedural success rates were similar (MAN 81%, 71% CF, and MNS 92%; P = 0.20). Median fluoroscopy time was shorter in the MNS group: MAN 29 (16-38), CF 37 (21-46), and MNS 13 (10-20) min (P = 0.002 for MNS vs. CF and MAN). The overall complication rate was: MAN 10%, CF 0%, and MNS 0% (P = 0.12). Median follow-up was: MAN 2184 (1672-2802), CF 1721 (1404-1913), and MNS 3031 (2524-3286) days (P <0.001). Recurrences occurred in MAN 46%, CF 50%, and MNS 46% (P = 0.97). Repeat procedures were performed in MAN 20%, CF 40%, and MNS 33% (P = 0.32). Conclusion: Procedural and long-term clinical outcome of OT IVA ablation are equal for MAN, CF, and MNS. MNS has a favourable procedural safety profile due to the shorter fluoroscopy time compared with MAN and CF.

A case-vignette based assessment of patient's perspective on coronary revascularization strategies, the OPINION study.

BACKGROUND AND AIMS: Significant left main (LM) stem disease is potentially life-threatening and mandates revascularization. This study aimed to assess how patients rate the importance of particular features of coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI), how this determines their preference for a particular treatment strategy, and whether particular personality characteristics influence this preference. METHODS AND RESULTS: In total, 1145 patients who visited the outpatient clinic of the Erasmus Medical Center for stable coronary artery disease were asked to complete a case vignette-questionnaire on a hypothetical significant LM stenosis amenable to PCI or CABG. To assess the individual's personality disposition and general distress level, each patient had to complete a set of 3 standardized, validated questionnaires with satisfactory psychometric properties. Overall 89% of patients preferred PCI to CABG. PCI was the preferred strategy despite a higher risk for repeat revascularization and need for more medication. Remarkably, the fact that a risk for repeat revascularization is more common in the PCI group is less important for the patients who opt for PCI. Risk for stroke and bleeding were the most important arguments to opt for PCI over CABG. Type D personality, depression, and anxiety were all associated with a relatively higher preference for CABG as revascularization strategy. CONCLUSION: Overall, when given the choice patients seem to have a clear preference for PCI over CABG and consider stroke and bleeding important procedure-related complications. Patients with Type D personality, depression, or anxiety favor CABG.

Coupling interval variability of premature ventricular contractions in patients with different underlying pathology: an insight into the arrhythmia mechanism.

PURPOSE: Coupling interval (CI) variability of premature ventricular contractions (PVCs) is influenced by the underlying arrhythmia mechanism. The aim of this study was to compare CI variability of PVCs in different myocardial disease entities, in order to gain insight into their arrhythmia mechanism. METHODS: Sixty-four patients with four underlying pathologies were included: idiopathic (n = 16), non-ischemic dilated cardiomyopathy (NIDCM) (n = 16), familial cardiomyopathy (PLN/LMNA) (n = 16), and post-MI (n = 16)-associated PVCs. The post-MI group was included as a reference, on account of its known re-entry mechanism. On Holter registrations, the first 20 CIs of the dominant PVC morphology were measured manually after which median ΔCI and mean SD of CI/√R-R (= CI of PVC corrected for underlying heart rate) were obtained. Two observers independently measured PVC CIs on pre-selected Holter registrations in order to determine inter- and intra-observer reliability. RESULTS: The largest ΔCI was seen in the PLN/LMNA group (220 ms (120-295)), the lowest in the idiopathic group (120 ms (100-190)). The ΔCI in the PLN/LMNA group was significantly larger than the post-MI group (220 ms (120-295) vs 130 ms (105-155), p = 0.023). Mean SD of CI/√R-R in the PLN/LMNA group was also significantly higher than in the post-MI group (p = 0.044). Inter- and intra-observer reliability was good (ICC = 0.91 vs 0.86 and 0.96 vs 0.77, respectively). CONCLUSIONS: Low ΔCI and SD of CI/√R-R of idiopathic and NIDCM PVCs suggest that the underlying arrhythmia mechanisms might be re-entry or triggered activity. Abnormal automaticity or modulated parasystole are unlikely mechanisms. High CI variability in PLN/LMNA patients suggests that the re-entry and triggered activity are less likely mechanisms in this group.

Randomised controlled trial of two advanced and extended cardiac rehabilitation programmes.

OBJECTIVE: The OPTICARE (OPTImal CArdiac REhabilitation) randomised controlled trial compared two advanced and extended cardiac rehabilitation (CR) programmes to standard CR for patients with acute coronary syndrome (ACS). These programmes were designed to stimulate permanent adoption of a heart-healthy lifestyle. The primary outcome was the SCORE (Systematic COronary Risk Evaluation) 10-year cardiovascular mortality risk function at 18 months follow-up. METHODS: In total, 914 patients with ACS (age, 57 years; 81% men) were randomised to: (1) 3 months standard CR (CR-only); (2) standard CR including three additional face-to-face active lifestyle counselling sessions and extended with three group fitness training and general lifestyle counselling sessions in the first 9 months after standard CR (CR+F); or (3) standard CR extended for 9 months with five to six telephone general lifestyle counselling sessions (CR+T). RESULTS: In an intention-to-treat analysis, we found no difference in the SCORE risk function at 18 months between CR+F and CR-only (3.30% vs 3.47%; p=0.48), or CR+T and CR-only (3.02% vs 3.47%; p=0.39). In a per-protocol analysis, two of three modifiable SCORE parameters favoured CR+F over CR-only: current smoking (13.4% vs 21.3%; p<0.001) and total cholesterol (3.9 vs 4.3 mmol/L; p<0.001). The smoking rate was also lower in CR+T compared with the CR-only (12.9% vs 21.3%; p<0.05). CONCLUSIONS: Extending CR with extra behavioural counselling (group sessions or individual telephone sessions) does not confer additional benefits with respect to SCORE parameters. Patients largely reach target levels for modifiable risk factors with few hospital readmissions already following standard CR. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov NCT01395095; results.

Navvus FFR to reduce CONTRAst, Cost and radiaTion (CONTRACT); insights from a single-centre clinical and economical evaluation with the RXi Rapid-Exchange FFR device.

OBJECTIVES: To assess whether the RXi Navvus system compared to the use of standard Fractional Flow Reserve (FFR) wires reduces total contrast volume, radiation and overall study cost in a real world patient population referred for coronary angiography or percutaneous coronary intervention. BACKGROUND: FFR is the mainstay of functional hemodynamic assessment of coronary artery lesions. The RXi Navvus system (ACIST Medical Systems, Eden Prairie, MN) is a monorail microcatheter with FFR-measurement capability through optical pressure sensor technology. METHODS: This is an investigator-initiated, prospective, single-center, observational cohort study. A total of 238 patients were enrolled, 97 patients with Navvus and 141 with conventional pressure-wire based FFR (PW-FFR). Final analyses were performed on the cohort in which only 1 device was used (82 Navvus procedures vs. 136 PW-FFR procedures). RESULTS: No significant differences were found in the total amount of contrast used (150±77 vs 147±79ml; p=0.81), radiation use (6200±4601 vs. 5076±4655 centiG∗cm2; p=0.09) or costs (€1994,- vs. €1930,-; p=0.32) in the Navvus vs. PW-FFR groups respectively. CONCLUSIONS: No significant differences were found in the amount of contrast used, total procedural costs or radiation when the Navvus system was used as compared to conventional FFR wires. CONDENSED ABSTRACT: CONTRACT is an investigator-initiated, prospective, single-center, observational cohort study that evaluated whether the RXi Navvus system compared to the use of standard Fractional Flow Reserve (FFR) wires reduces total contrast volume, radiation and overall study cost in a real world patient population referred for coronary angiography or percutaneous coronary intervention. Use of the RXi Navvus system was associated with comparable procedural costs, amount of radiation and contrast used as compared to PW-FFR systems.

Determinants of aortic regurgitation after transcatheter aortic valve implantation. An observational study using multi-slice computed tomography-guided sizing.

BACKGKGROUND: The aim of this paper was to explore the determinants of aortic regurgitation (AR) after transcatheter aortic valve implantation (TAVI) using multi-slice computed tomography (MSCT) instead of echocardiography-guided sizing. METHODS: Determinants of AR were assessed in 313 consecutive patients who underwent TAVI with the Medtronic (MCS, N.=259) or Edwards Sapien or XT (ESV, N.=54) using MSCT-guided sizing. AR was assessed by angiography immediately after TAVI (N.=313, Sellers) and by echocardiography at discharge (N.=285, VARC-2). Distinction was made between patients with grade 0-1 and grade ≥2 AR post-TAVI. RESULTS: AR≥2 post-TAVI was seen in 91 patients or 29% (MCS 85/259: 33% vs. ESV 6/54:11%) by angiography and 94 patients or 33% (MCS 87/239:36% vs. ESV 7/46:15%) by echocardiography. By univariable analysis, patients with AR≥2 post TAVI had more AR≥2 at baseline (70% vs. 52%, P=0.003), a larger mean and maximal annulus diameter (25.0 [23.5-26.3] vs. 24.0 [22.6-26.0], P=0.025 and 27.9±2.7 mm vs. 27.0±2.8 mm, P=0.018, respectively) and a higher Agatston Score (3.9 [2.9-5.3] vs. 2.6 [1.8-3.8], P≤0.001). AR≥2 post-TAVI was more frequent after MCS than ESV (33% vs. 11%, P=0.001). There was no difference in nominal valve size relative to the patient's annulus, nor depth of implantation. By propensity score adjusted multivariable analysis, AR≥2 at baseline (odds 2.407 [95% CI: 1.472-3.938]) but above all MCS (odds: 6.047 [95% CI; 1.307- 27.976]) were independent determinants of AR≥2 post-TAVI. The latter was also confirmed by propensity score adjusted multivariable analysis in the echocardiography population (N.=285) (odds: 5.259 [95% CI; 1.070-25.851]). CONCLUSIONS: AR≥2 is more prevalent after MCS valve implantation and is an independent determinant of AR also when using MSCT guided-sizing.

Psychosocial needs of children undergoing an invasive procedure for a CHD and their parents.

OBJECTIVE: The aim of this study was to investigate the psychosocial needs of both parents of children with CHD (aged 0-18 years) and patients themselves (aged 8-18 years) in the week before cardiac surgery or a catheter intervention. Patients Eligible participants included all consecutive patients (0-18 years) scheduled to undergo cardiac surgery or a catheter intervention in our hospital between March, 2012 and July, 2013. Psychosocial needs were assessed using a disease-specific questionnaire designed for this study, consisting of a 83-item parent version and a 59-item child version (for children ⩾8 years), each covering five domains: physical/medical, emotional, social, educational/occupational, and health behaviour; two items assessed from whom and in what format psychosocial care was preferred. Quality of life was also assessed. Interventions If parents/patients reported a need for psychosocial care, referral to adequate mental health-care professionals was arranged. RESULTS: More than 40% of participating parents and >50% of participating children reported a need for psychosocial care on each of the five domains. Needs for psychosocial care for parents themselves were highest for those with children aged 0-12 years. Parents and patients report clear preferences when asked from whom and in what format they would like to receive psychosocial care. Quality of life was relatively high for both parents and patients. Psychosocial care interventions in our hospital increased significantly after the implementation of this study. CONCLUSIONS: Results show that psychosocial care is rated as (very) important by both parents and children during an extremely stressful period of their life.

The unnatural history of pulmonary stenosis up to 40†years after surgical repair.

OBJECTIVE: To provide prospective information on long-term outcome after surgical correction of valvular pulmonary stenosis (PS). METHODS: Fifty-three consecutive patients operated for PS during childhood between 1968 and 1980 in one centre are followed longitudinally for 37±3.4 years, including extensive in-hospital examination every 10 years. RESULTS: Survival information was available in 100% of the original 53 patients. Cumulative survival was 94% at 20 years and 91% at 40 years. Excluding perioperative mortality (<30 days), survival was 94% at 40 years. Of 46 eligible survivors, 29 participated in the in-hospital examination and 15 gave permission to use their hospital records (96% participation). Cumulative event-free survival was 68% after 40 years: 25% needed a reintervention, 12% underwent pacemaker implantation and 9% had supraventricular arrhythmias. Early reinterventions were mainly for residual PS, late reinterventions for pulmonary regurgitation. Subjective health status was good. Exercise capacity was normal in 74% (median 96 (82-107)% of expected workload). Right ventricular and left ventricular (LV) dysfunction was found in 13% and 41%, respectively. The use of a transannular patch and younger age at surgery were predictive for late events (HR 3.02 (95% CI 1.09 to 8.37) and HR 0.81/year (95% CI 0.66 to 0.98), respectively). Use of inflow occlusion compared with cardiopulmonary bypass showed a trend towards more reinterventions (HR 3.19 (95% CI 0.97 to 10.47)). CONCLUSIONS: Survival up to 40 years after successful PS repair is nearly normal. Subjective health status is good and there is a low incidence of arrhythmias. Reinterventions, however, are necessary in one-quarter and 40 years postoperatively several patients show LV dysfunction.

Impact of Early Coronary Revascularization on Long-Term Outcomes in Patients With Myocardial Ischemia on Dobutamine Stress Echocardiography.

The role of early coronary revascularization in the management of stable coronary artery disease remains controversial. The aim of this study was to evaluate the impact of early coronary revascularization on long-term outcomes (>10 years) after an ischemic dobutamine stress echocardiography (DSE) in patients with known or suspected coronary artery disease. Patients without stress-induced ischemia on DSE and those who underwent late coronary revascularization (>90 days after DSE) were excluded. The final study cohort consisted of 905 patients. A DSE with a peak wall motion score index of 1.1 to 1.7 was considered mild to moderately abnormal (n = 460), and >1.7 was markedly abnormal (n = 445). End points were all-cause and cardiac mortality. The impact of early coronary revascularization on outcomes was assessed using Kaplan-Meier survival analysis and Cox's proportional hazard regression models. Early coronary revascularization was performed in 222 patients (percutaneous coronary intervention in 113 [51%] and coronary artery bypass grafting in 109 patients [49%]). During a median follow-up time of 10 years (range 8 to 15), 474 deaths (52%) occurred, of which were 241 (51%) due to cardiac causes. Kaplan-Meier survival curves showed that both in patients with a markedly abnormal DSE and a mild-to-moderately abnormal DSE, early revascularization was associated with better long-term outcomes. Multivariable analyses revealed that early revascularization had a beneficial effect on all-cause mortality (hazard ratio 0.60, 95% confidence interval 0.46 to 0.79) and cardiac mortality (hazard ratio 0.49, 95% confidence interval 0.34 to 0.72). In conclusion, early coronary revascularization has a beneficial impact on long-term outcomes in patients with myocardial ischemia on DSE. Early coronary revascularization was associated with better outcomes not only in patients with a markedly abnormal DSE but also in those with a mild to moderately abnormal DSE.

Longitudinal development of psychopathology and subjective health status in CHD adults: a 30- to 43-year follow-up in a unique cohort.

OBJECTIVE: To determine longitudinal changes in psychopathology in a cohort of patients 30-43 years after their first cardiac surgery for Congenital Heart Disease (CHD) in childhood, to compare outcomes of the 30- to 43-year follow-up with normative data, and to identify medical predictors for psychopathology. METHODS: This study is the third follow-up of this cohort. The first and second follow-ups of this same cohort were conducted in 1990 and 2001, respectively. At all three follow-ups, psychopathology was assessed with standardised, parallel questionnaires. In 2011, subjective health status was assessed by the Short Form-36. Medical predictor variables were derived from medical examinations and medical records. RESULTS: In this third follow-up, a total of 252 patients participated. Of these, 152 patients participated in all three follow-ups. Over a 30-year period, proportions of patients showing psychopathology decreased significantly. At the 30- to 43-year follow-up, overall outcomes on psychopathology for the CHD sample were similar or even better compared with normative groups. Subjective health status was also better compared with normative data. No differences were found between cardiac diagnostic groups. Medical variables that predicted the course of psychopathology over time were as follows: the scar, as judged by the patient, results of the first cardiac surgery, and the number of hospitalisations. CONCLUSIONS: Over a 30-year period, psychopathology decreased in patients with CHD. Levels of psychopathology in these patients, who are now aged between 30 and 54 years, were comparable or even better than normative data.

The unnatural history of the ventricular septal defect: outcome up to 40 years after surgical closure.

BACKGROUND: Few prospective data are available regarding long-term outcomes after surgical closure of a ventricular septal defect (VSD). OBJECTIVES: The objective of this study was to investigate clinical outcomes>30 years after surgical VSD closure. METHODS: Patients who underwent surgical VSD closure during childhood between 1968 and 1980 were reexamined every 10 years. In 2012, we invited eligible patients to undergo another examination, which included electrocardiography, Holter monitoring, echocardiography, bicycle ergometry, measurement of N-terminal pro-B-type natriuretic peptide, and subjective health assessment. RESULTS: Cumulative survival was 86% at 40 years. Causes of mortality were arrhythmia, heart failure, endocarditis, during valvular surgery, pulmonary hypertension, noncardiac causes, and unknown causes. Cumulative event-free survival after surgery was 72% at 40 years. Symptomatic arrhythmias occurred in 13% of patients and surgical or catheter-based reinterventions in 12%. Prevalence of impaired right ventricular systolic function increased from 1% in 2001 to 17% in 2012 (p=0.001). Left ventricular systolic function was impaired but stable in 21% of patients. Aortic regurgitation occurred more often in the last 20 years (p=0.039), and mean exercise capacity decreased (p=0.003). N-terminal pro-B-type natriuretic peptide (median: 11.6 pmol/l [interquartile range: 7.0 to 19.8 pmol/l]) was elevated (>14 pmol/l) in 38% of patients. A concomitant cardiac lesion, for example, patent ductus arteriosus, and aortic cross-clamp time were determinants of late events (hazard ratio: 2.84 [95% confidence interval: 1.23 to 6.53] and hazard ratio: 1.47 per 10 min [95% confidence interval: 1.22 to 1.99], respectively). Patients rated their subjective health status significantly better than a reference population. CONCLUSIONS: Survival up to 40 years after successful surgical VSD closure is slightly lower than in the general Dutch population. Morbidity is not negligible, especially in patients with a concomitant cardiac lesion.

Sports participation in adults with congenital heart disease.

BACKGROUND: It is unclear whether sports participation in adults with repaired congenital heart disease is safe and has benefits. METHODS: Congenital heart disease (ConHD) patients who underwent corrective surgery for Atrial Septal Defect, Ventricular Septal Defect, Pulmonary Stenosis, Tetralogy of Fallot or Transposition of the Great Arteries in our center between 1968 and 1980 were included, and participated in our longitudinal follow-up study with serial evaluations in 2001 and 2011. At both time points patients filled in questionnaires on sports participation, subjective physical functioning and quality of life. Exercise testing, echocardiogram and 24-hour continuous ambulatory ECG-monitoring were performed in both 2001 and 2011. All clinical events (re-intervention, arrhythmia, heart failure) were prospectively recorded. RESULTS: No relationship was found between practicing sports and the occurrence of sudden death, PVCs or SVTs. Patients with moderate/complex forms of ConHD practiced fewer hours of sports compared with the general Dutch normative population. Patients with both simple and moderate/complex ConHD who practiced sports showed a higher exercise capacity. More favorable subjective physical functioning was found for moderate/complex patients who practiced sports. CONCLUSIONS: Adults with repaired ConHD are less often involved in sports than the Dutch general population. The patients that were engaged in sports show a higher exercise capacity than those who did not. Sports participation in patients with ConHD was not associated with an increased incidence of adverse cardiac events.

Long-term outcomes of transatrial-transpulmonary repair of tetralogy of Fallot.

OBJECTIVES: The surgical approach to repair of tetralogy of Fallot (ToF) has shifted over the years. We aimed to report the long-term follow-up after ToF repair with the transatrial-transpulmonary approach and to determine predictors of long-term outcomes. METHODS: Retrospective analysis of patients operated on in two tertiary referral centres. Primary outcome measures were: death, pulmonary valve replacement (PVR), reintervention for other reasons, internal cardiodefibrillator and/or pacemaker placement. Kaplan-Meier assessment of overall and event-free survival as well as uni- and multivariate analyses of risk factors for outcomes were performed. RESULTS: Four hundred and fifty-three patients were included. Median age at operation was: 0.6 years (range 0-19.6) and median age at the last follow-up was 14.3 years (range 0.1-42.1). Median age at repair decreased from 1.2 years (range 0.6-5.8) (1970-80) to 0.3 years (range 0-4.7) (2000-12). A transannular patch (TP) was used in 65% of all patients. The use of a TP showed a decline from 89% in the initial years of the cohort to 64% in 2000-12. Early mortality was 1.1% (5 patients) for the entire cohort and late mortality 2.4% (11 patients). Overall survival for the entire cohort was 97.3% (95% CI 95.7-98.8) and 91.8% (95% CI 85.9-97.7) at 10 and 25 years, respectively. For patients with a TP (n = 294) vs non-TP (n = 159), this was 97.2% (95% CI 95.2-99.2) vs 97.5% (95% CI 95.1-99.9) at 10-year and 91.0% (95% CI 83.9-98.1) vs 96.3% (95% CI 93.0-99.6) at 25-year follow-up (P = 0.958). Fifty-two patients underwent PVR, and in 5 a pacemaker was inserted. Event-free survival for TP versus non-TP patients was 80.2% (95 CI% 75.5-84.9) vs 81.7% (95% CI 75.2-88.2) at 10-year and 27.9% (95% CI 17.7-38.1) vs 78.5% (95% CI 71.4-85.6) at 25-year follow-up (P = 0.016). In multivariate analysis, both the use of a TP (HR 1.705, 95% CI 1.023-2.842) and the year of surgical repair of tetralogy of Fallot (HR 1.039, 95% CI 1.006-1.073) were associated with a higher probability of an event. CONCLUSIONS: ToF patients corrected with the transatrial-transpulmonary approach have good long-term survival. PVR is a frequent event at longer follow-up, and other events are limited. The use of a TP is a predictor for poorer event-free outcomes, increasing the risk of the composite endpoint 1.7 times.

Differences in coronary risk factors, procedural characteristics, mortality and stent thrombosis between two all-comers percutaneous coronary intervention registries from Europe and Japan: a patient-level data analysis of the Bern-Rotterdam and j-Cypher registries.

AIMS: The reported rate of stent thrombosis (ST) after drug-eluting stent (DES) implantation varies among registries. To investigate differences in baseline characteristics and clinical outcome in European and Japanese all-comers registries, we performed a pooled analysis of patient-level data. METHODS AND RESULTS: The j-Cypher registry (JC) is a multicentre observational study conducted in Japan, including 12,824 patients undergoing SES implantation. From the Bern-Rotterdam registry (BR) enrolled at two academic hospitals in Switzerland and the Netherlands, 3,823 patients with SES were included in the current analysis. Patients in BR were younger, more frequently smokers and presented more frequently with ST-elevation myocardial infarction (MI). Conversely, JC patients more frequently had diabetes and hypertension. At five years, the definite ST rate was significantly lower in JC than BR (JC 1.6% vs. BR 3.3%, p<0.001), while the unadjusted mortality tended to be lower in BR than in JC (BR 13.2% vs. JC 14.4%, log-rank p=0.052). After adjustment, the j-Cypher registry was associated with a significantly lower risk of all-cause mortality (HR 0.56, 95% CI: 0.49-0.64) as well as definite stent thrombosis (HR 0.46, 95% CI: 0.35-0.61). CONCLUSIONS: The baseline characteristics of the two large registries were different. After statistical adjustment, JC was associated with lower mortality and ST.
