Right coronary sinus aneurysm repair.

In this case report, we describe the surgical treatment of a right coronary sinus aneurysm. A 69-year-old male patient was screened because of palpitations. He was finally diagnosed with an aneurysm of the sinus of Valsalva of the right coronary cusp. According to current aortic guidelines, surgical reconstruction was proposed. The patient underwent a cardiac operation through a median sternotomy under routine cardiopulmonary bypass. After aortic cross-clamping, the aorta was opened and the connection between the aorta and the aneurysm was clearly visualized, underneath the ostium of the right coronary artery. After excision of the right coronary button and the remaining right coronary sinus wall, this sinus was reconstructed with a Dacron graft, with subsequent coronary reimplantation. The postoperative course was uneventful. The patient was discharged on postoperative day 7. A complete sinus reconstruction was preferred over local patching of the defect because of the proximity of the aneurysm sac to the right coronary artery and the fragile, thin aortic tissue just underneath the coronary ostium.

Clinical Impact of the Endo-aortic Clamp for Redo Mitral Valve Surgery.

Aim of this study was to compare redo MV surgery patients undergoing right mini-thoracotomy and EAC with redo MV patients undergoing surgery through other approaches. Redo MV patients from 7 European centers were analyzed. Primary endpoint was 30-day mortality; secondary endpoints were stroke, re-exploration, low cardiac output syndrome (LCOS), respiratory failure, and intensive care unit (ICU) and in-hospital length-of-stay. Forty-nine patients underwent right mini-thoracotomy and EAC (22.7%), and 167 (77.3%) underwent surgery through other approaches (112 sternotomy, 40 unclamped mini-thoracotomies, and 15 mini-thoracotomies with trans-thoracic clamp). Thirty-day mortality, stroke, re-exploration for bleeding, and weaning failure were comparable. The EAC group showed significant lower rate of LCOS (p = 0.03) and shorter ICU (p = 0.04) and in-hospital length of stay (p = 0.002). The EAC allows the surgeon to reach the aorta, to clamp it, and to deliver the cardioplegia with a "no-touch" technique, with significant improvement in outcomes.

Long-term follow-up of atrioventricular valve function in Fontan patients: effect of atrioventricular valve surgery.

OBJECTIVES: The aim of this study was to evaluate the relationship between atrioventricular valve and ventricular function in Fontan survivors, including the effect of atrioventricular valve surgery. METHODS: Analysis focused on transplant-free survival and the need for atrioventricular valve surgery in single ventricle patients after Fontan completion. Longitudinal echocardiographic examination of long-term valve and ventricular function was performed. RESULTS: Fontan completion was performed in 113 patients, having a right univentricular morphology in 33.6%, a left ventricle morphology in 62.8% and ambiguous in 3.6%. Perioperative mortality was 2.7% (n = 3). Within a median follow-up of 16.3 years (interquartile range 10.6-23.6), transplant-free survival was 96.1 ± 1.9% and 90.4 ± 5.8% at 10-25 years. Twenty AV valve procedures were performed in 14 (12.4%) children, respectively, pre-Fontan (n = 10), per-Fontan (n = 8) and post-Fontan (n = 2), resulting in a cumulative incidence of AV valve surgery is 5.7 ± 2.2% and 12.3 ± 3.2% at 1-5 years. Atrio-ventricular valve function deteriorated over time [hazard ratio (HR) 1.112, 95% confidence interval (CI) 1.089-1.138, P < 0.001], without difference for valve morphology (P = 0.736) or ventricular dominance (P = 0.484). AV valve dysfunction was greater in patients requiring AV valve surgery (HR 20.383, 95% CI 6.223-36.762, P < 0.001) but showed a comparable evolution since repair to those without valve surgery (HR 1.070, 95% CI 0.987-1.160, P = 0.099). Progressive time-related ventricular dysfunction was observed (HR 1.141, 95% CI 1.097-1.182, P < 0.001), significantly less in left ventricle-dominance (HR 0.927, 95% CI 0.860-0.999, P = 0.047) but more after AV valve surgery (HR 1.103, 95% CI 1.014-1.167, P = 0.022). CONCLUSIONS: In a homogeneously treated Fontan population, 25-year transplant-free survival is encouraging. Atrio-ventricular valve surgery was necessary in 12.4%, resulting mostly in a durable valve function. However, a slow time-related decline of atrioventricular valve function as of ventricular function is worrisome, evoking a role for additional heart failure therapy.

Potential of Urine Biomarkers CHI3L1, NGAL, TIMP-2, IGFBP7, and Combinations as Complementary Diagnostic Tools for Acute Kidney Injury after Pediatric Cardiac Surgery: A Prospective Cohort Study.

Acute kidney injury (AKI) is common after pediatric cardiac surgery (CS). Several urine biomarkers have been validated to detect AKI earlier. The objective of this study was to evaluate urine CHI3L1, NGAL, TIMP-2, IGFBP7, and NephroCheck® as predictors for AKI ≥ 1 in pediatric CS after 48 h and AKI ≥ 2 after 12 h. Pediatric patients (age < 18 year; body weight ≥ 2 kg) requiring CS were prospectively included. Urine CHI3L1, NGAL, TIMP-2, IGFBP7, and NephroCheck® were measured during surgery and intensive care unit (ICU) stay and corrected for urine dilution. One hundred and one pediatric patients were included. AKI ≥ 1 within 48 h after ICU admission occurred in 62.4% and AKI ≥ 2 within 12 h in 30.7%. All damage biomarkers predicted AKI ≥ 1 within 48 h after ICU admission, when corrected for urine dilution: CHI3L1 (AUC-ROC: 0.642 (95% CI, 0.535-0.741)), NGAL (0.765 (0.664-0.848)), TIMP-2 (0.778 (0.662-0.868)), IGFBP7 (0.796 (0.682-0.883)), NephroCheck® (0.734 (0.614-0.832)). Similarly, AKI ≥ 2 within 12 h was predicted by all damage biomarkers when corrected for urine dilution: uCHI3L1 (AUC-ROC: 0.686 (95% CI, 0.580-0.780)), NGAL (0.714 (0.609-0.804)), TIMP-2 (0.830 (0.722-0.909)), IGFBP7 (0.834 (0.725-0.912)), NephroCheck® (0.774 (0.658-0.865)). After pediatric cardiac surgery, the damage biomarkers urine CHI3L1, NGAL, TIMP-2, IGFBP7, and NephroCheck® reliably predict AKI after correction for urine dilution.

Pulmonary artery banding as adjunct therapy for ventricular recovery after anomalous left coronary artery from the pulmonary artery repair: a case report.

Anomalous left coronary artery from the pulmonary artery is a rare congenital coronary anomaly commonly associated with severe but reversible left ventricular dysfunction. We present an anomalous left coronary artery from the pulmonary artery case of persisting left ventricular failure with inability to wean off the ventilator and inotropes after successful coronary reimplantation, in whom pulmonary artery banding enhanced myocardial recovery.

Impact of mean perfusion pressure and vasoactive drugs on occurrence and reversal of cardiac surgery-associate acute kidney injury: A cohort study.

PURPOSE: Low cardiac output and kidney congestion are associated with acute kidney injury after cardiac surgery (CSA-AKI). This study investigates hemodynamics on CSA-AKI development and reversal. MATERIALS AND METHODS: Adult patients undergoing cardiac surgery were retrospectively included. Hemodynamic support was quantified using a new time-weighted vaso-inotropic score (VISAUC), and hemodynamic variables expressed by mean perfusion pressure and its components. The primary outcome was AKI stage ≥2 (CSA-AKI ≥2) and secondary outcome full AKI reversal before ICU discharge. RESULTS: 3415 patients were included. CSA-AKI ≥2 occurred in 37.4%. Mean perfusion pressure (MPP) (OR 0.95,95%CI 0.94-0.96, p < 0.001); and central venous pressure (CVP) (OR 1.17, 95%CI 1.13-1.22, p < 0.001) are associated with CSA-AKI ≥2 development, while VISAUC/h was not (p = 0.104). Out of 1085 CSA-AKI ≥2 patients not requiring kidney replacement therapy, 76.3% fully recovered of AKI. Full CSA-AKI reversal was associated with MPP (OR 1.02 per mmHg (95%CI 1.01-1.03, p = 0.003), and MAP (OR = 1.01 per mmHg (95%CI 1.00-1.02), p = 0.047), but not with VISAUC/h (p = 0.461). CONCLUSION: Development and full recovery of CSA-AKI ≥2 are affected by mean perfusion pressure, independent of vaso-inotropic use. CVP had a significant effect on AKI development, while MAP on full AKI reversal.

Clipping of an Aortopulmonary Window in a Small Neonate With Bronchial Bleeding: A Simple Solution for a Complex Condition.

Although the conventional treatment of aortopulmonary (AP) window consists of reconstructive surgery with the use of cardiopulmonary bypass (CPB), some conditions like low birth weight or active respiratory tract bleeding may lead to diverting therapeutic options. We present a case of a premature 1.9 kg neonate with severe pulmonary arterial hypertension based on the association of an AP window and large patent ductus arteriosus. Because of intrabronchial hemorrhage, a conservative strategy was chosen excluding the need for heparinization and CPB. Through median sternotomy, the ductus arteriosus and AP window were clipped, effectively occluding both shunts. The postoperative course was uneventful with a rapid decrease of pulmonary artery pressure. Although classical surgical reconstruction is still advocated as primary therapy, this case illustrates the suitability of an alternative approach without the need for CPB and full heparinization in a patient with an increased risk of bleeding complications.

Mid-term clinical and haemodynamic results after aortic valve replacement with the Trifecta bioprosthesis.

OBJECTIVES: The aim of this study was to evaluate the clinical and haemodynamic results after implantation of the Trifecta bioprosthesis. METHODS: This study is a retrospective analysis of all patients undergoing Trifecta aortic valve replacement between 01 January 2012 and 31 December 2017 at the Ghent University Hospital. Univariable and multivariable analyses were performed to identify predictors of valve- and procedure-related complications and mortality. The haemodynamic performance was analysed by longitudinal Doppler echocardiography. RESULTS: The mean age of the 182 patients was 77 [standard deviation (SD): 5.5] years; 54.9% were women. The mean follow-up was 39.8 (SD: 24.3) months. Overall survival at 1 and 5 years was 86% (SD: 3%) and 68% (SD: 4%), respectively, and overall freedom from structural valve deterioration was 100% and 98% at 1 and 5 years, respectively. There was no valve thrombosis nor early endocarditis. Urgent surgery was the only risk factor for early mortality in the multivariable analysis [P = 0.009, odds ratio 0.06, 95% confidence interval (CI) 0.01-0.5]. Preoperative atrial fibrillation was the most important predictor of late mortality (P = 0.001, hazard ratio 3.68, 95% CI 1.65-8.21). The average peak gradients were stable from discharge up to 1 and 5 years postoperatively [15 (SD: 6) and 17 (SD: 8) mmHg]. CONCLUSIONS: These results confirm the excellent clinical performance of the Trifecta valve, particularly in an elderly age group. Through the 7-year follow-up period, low transvalvular gradients persisted, and only a few patients needed reoperation. Although structural valve degeneration occurred rarely, it was unrelated to valve size or age at implantation; therefore, further long-term follow-up remains mandatory.

Early Conduction Disorders After Aortic Valve Replacement With the Sutureless Perceval Prosthesis.

BACKGROUND: This study was conducted to determine the incidence of postoperative conduction disorders and need for pacemaker (PM) implantation after aortic valve replacement (AVR) with the Perceval prosthesis (Livanova, Saluggia, Italy). METHODS: From January 2007 to December 2017, 908 patients underwent AVR with Perceval S in 5 participating centers. Study end points focused on electrocardiographic changes after AVR and the incidence of new PM implantation in 801 patients after exclusion of patients with previous PM (n = 48) or patients undergoing tricuspid (n = 28) and/or atrial fibrillation ablation (n = 31) surgery. Logistic regression analysis was performed to determine risk factors for PM need. RESULTS: Mean age was 79.7 ± 5.2 years, and 476 (59.4%) were women. Median logistic European System for Cardiac Operative Risk Evaluation (2011 revision) score was 4.1% (interquartile range, 2.6%-6.0%). Isolated AVR was performed in 441 patients (55.1%). Associated procedures were coronary artery bypass grafting in 309 (38.6%) and mitral valve surgery in 51 (6.4%). Overall 30-day mortality was 3.9% and was 2.8% for isolated AVR. Electrocardiographic changes included a significant increase of left bundle branch block from 7.4% to 23.7% (P < .001) and development of complete atrioventricular block requiring PM implantation in 9.5%. Multivariable analysis revealed independent of a learning period (odds ratio [OR], 1.91; 95% confidence limits (CL), 1.16-3.13; P = .011), preexisting right-bundle branch block (OR, 2.77; 95% CL, 1.40-5.48; P = .003), intraoperative prosthesis repositioning (OR, 6.70; 95% CL, 1.89-24.40; P = .003), and size extra large (OR, 6.81; 95% CL, 1.55-29.96; P = .011) as significant predictors of PM implantation. CONCLUSIONS: In a challenging elderly population, use of the Perceval S for AVR provides low operative mortality but at the risk of an increased PM implantation rate. Besides preexisting right bundle branch block, the significant effect of size extra large, an increased valve size/body surface area ratio, and need for intraoperative repositioning on PM rate are underscoring the reappraisal of the annular sizing policy.

Long-term outcomes of atrioventricular septal defect and single ventricle: A multicenter study.

OBJECTIVE: The study objective was to analyze survival and incidence of Fontan completion of patients with single-ventricle and concomitant unbalanced atrioventricular septal defect. METHODS: Data from 4 Dutch and 3 Belgian institutional databases were retrospectively collected. A total of 151 patients with single-ventricle atrioventricular septal defect were selected; 36 patients underwent an atrioventricular valve procedure (valve surgery group). End points were survival, incidence of Fontan completion, and freedom from atrioventricular valve reoperation. RESULTS: Median follow-up was 13.4 years. Cumulative survival was 71.2%, 70%, and 68.5% at 10, 15, and 20 years, respectively. An atrioventricular valve procedure was not a risk factor for mortality. Patients with moderate-severe or severe atrioventricular valve regurgitation at echocardiographic follow-up had a significantly worse 15-year survival (58.3%) compared with patients with no or mild regurgitation (89.2%) and patients with moderate regurgitation (88.6%) (P = .033). Cumulative incidence of Fontan completion was 56.5%, 71%, and 77.6% at 5, 10, and 15 years, respectively. An atrioventricular valve procedure was not associated with the incidence of Fontan completion. In the valve surgery group, freedom from atrioventricular valve reoperation was 85.7% at 1 year and 52.6% at 5 years. CONCLUSIONS: The long-term survival and incidence of Fontan completion in our study were better than previously described for patients with single-ventricle atrioventricular septal defect. A concomitant atrioventricular valve procedure did not increase the mortality rate or decrease the incidence of Fontan completion, whereas patients with moderate-severe or severe valve regurgitation at follow-up had a worse survival. Therefore, in patients with single-ventricle atrioventricular septal defect when atrioventricular valve regurgitation exceeds a moderate degree, the atrioventricular valve should be repaired.

Midterm Comparison Between Different Annuloplasty Techniques for Functional Tricuspid Regurgitation.

BACKGROUND: Several tricuspid annuloplasty (TA) techniques are used for concomitant repair of functional tricuspid regurgitation (TR). This study compared the midterm clinical and valvular outcome among 3 annuloplasty techniques. METHODS: TA was performed in 307 patients (aged 75.9 ± 10.4 years) with a rigid ring (RA) in 184, a flexible band (FA) in 80, or a suture annuloplasty (SA) in 43. Study end points were survival and recurrence of TR >grade 2 at 5 years. RESULTS: TA was performed concomitantly to mitral valve surgery in 136 patients (44.3%), aortic valve surgery in 18 (5.9%), coronary artery bypass grafting in 13 (4.2%), or a combined procedure in 140 (45.6%). Most had TR >grade 2 (78.5%), without significant differences between the TA groups (P = .878). Within a median follow-up of 3.4 years (interquartile range, 2.2-5.0 years), the 5-year survival was 80.1% ± 3.4% for RA, 83.5% ± 4.7% for FA, and 85.1% ± 6.5% for SA (P = .471). Independent risk factors for late mortality were renal impairment (hazard ratio [HR], 2.83; 95% CI, 1.16-6.89; P = .022), diabetes (HR, 2.10; 95% CI, 1.07-4.11; P = .030), and severe right ventricular dysfunction by tricuspid annulus plane systolic excursion <10 mm (HR, 11.52; 95% CI, 4.98-26.66; P < .001). Pulmonary hypertension was nearly significant (HR, 1.92; 95% CI, 0.98-3.74; P = .057). The cumulative incidence of TR recurrence at 5 years was 15.9%, 19.4%, and 21.1% for RA, FA, and SA, respectively (P = .342). Severe pulmonary hypertension (HR, 2.64; 95% CI, 1.38-5.07; P = .003), preoperative TR grade (HR, 1.82; 95% CI, 1.01-3.27; P = .046), and residual TR >grade 2 at discharge (HR, 3.38; 95% CI, 1.64-6.96; P = .001) were predictive for later TR recurrence, regardless of the annuloplasty technique. CONCLUSIONS: This study demonstrates that advanced pathophysiological right circulatory impairment, such as severe pulmonary hypertension and right ventricular dysfunction, affects the midterm survival and TR recurrence rate more than the annuloplasty technique used for concomitant repair of functional TR.

Non-invasive assessment of liver abnormalities in pediatric Fontan patients.

Liver abnormalities are well known among long-term survivors of Fontan palliation, which remains the definite surgery for complex congenital heart disease and single ventricle physiology. Pediatric data however are scarce. We assessed the prevalence and degree of liver abnormalities in pediatric Fontan patients through non-invasive investigations suitable for longitudinal follow-up. Thirty-five patients with a median age of 11.8 years (5.2-16.6) and median time since Fontan of 6 years (1.17-13.83) were studied. Each child underwent a blood test, liver Doppler ultrasound (US), and transient elastography (TE). Healthy children were used as controls for TE measurement. AST, ALT, γGT, and direct bilirubin were abnormal in respectively 12 (34%), 5 (14%), 24 (69%), and 7 (20%) patients, while platelet count was decreased in 7 (20%). Splenomegaly was present in 7 (20%) patients. Portal vein mean flow velocity was < 15 cm/s in 19 (54%) patients indicative of portal hypertension. Twenty-two patients (63%) showed inferior vena cava collapsibility index values below 17%, indicating venous congestion. Hepatic artery and superior mesenteric artery resistance index were inversely correlated with time post Fontan (p < 0.05). TE values in Fontan patients were significantly higher than controls, with a median of 12.6 versus 4.6 kPa (p < 0.001) and were already increased shortly after Fontan completion. Conclusion: Liver abnormalities are frequently observed in pediatric Fontan patients. The non-invasive investigations used were not able to confirm liver fibrosis or differentiate hepatic congestion from fibrosis. Based on our findings, we propose a prospective screening protocol with serial measurements of laboratory, (Doppler) US, and TE parameters. What is Known: • Hepatic dysfunction is a well-known consequence of the Fontan circulation. • The natural history of Fontan-associated liver disease in the pediatric age group remains unclear. What is New: • Liver abnormalities are frequently observed in pediatric Fontan patients; however, differentiating liver fibrosis and hepatic congestion with non-invasive investigations remains challenging. Sonographic Doppler measurements may improve our insight in both Fontan-associated liver disease development and the functioning of the Fontan circulation. • A prospective screening protocol is proposed to improve our ability to detect Fontan-associated liver disease early on and understand its natural history.

Paediatric subaortic stenosis: long-term outcome and risk factors for reoperation.

OBJECTIVES: Surgical repair of subaortic stenosis (SAS) is associated with a substantial reoperation risk. We aimed to identify risk factors for reintervention in relation to discrete and tunnel-type SAS morphology. METHODS: Single-centre retrospective study of paediatric SAS diagnosed between 1992 and 2017. Multivariable Cox regression analysis was performed to identify reintervention risk factors. RESULTS: Eighty-five children [median age 2.5 (0.7-6.5) years at diagnosis] with a median follow-up of 10.1 (5.5-16.4) years were included. Surgery was executed in 83% (n = 71). Freedom from reoperation was 88 ± 5% at 5 years and 82 ± 6% at 10 years for discrete SAS, compared to, respectively, 33 ± 16% and 17 ± 14% for tunnel-type SAS (log-rank P < 0.001). Independent risk factors for reintervention were a postoperative gradient >20 mmHg [hazard ratio (HR) 6.56, 95% confidence interval (CI) 1.41-24.1; P = 0.005], tunnel-type SAS (HR 7.46, 95% CI 2.48-22.49; P < 0.001), aortic annulus z-score <-2 (HR 11.07, 95% CI 3.03-40.47; P < 0.001) and age at intervention <2 years (HR 3.24, 95% CI 1.09-9.86; P = 0.035). Addition of septal myectomy at initial intervention was not associated with lesser reintervention. Fourteen children with a lower left ventricular outflow tract (LVOT) gradient (P < 0.001) and older age at diagnosis (P = 0.024) were followed expectatively. CONCLUSIONS: Children with SAS remain at risk for reintervention, despite initially effective LVOT relief. Regardless of SAS morphology, age <2 years at first intervention, a postoperative gradient >20 mmHg and presence of a hypoplastic aortic annulus are independent risk factors for reintervention. More extensive LVOT surgery might be considered at an earlier stage in these children. SAS presenting in older children with a low LVOT gradient at diagnosis shows little progression, justifying an expectative approach.

QRS Duration During Follow-Up of Tetralogy of Fallot: How Valuable is it? Analysis of ECG Changes in Relation to Pulmonary Valve Implantation.

Long-term results after tetralogy of Fallot (TOF) repair are determined by the extent of right ventricular remodeling to chronic pulmonary regurgitation entailing progressive RV dysfunction and a risk of developing ventricular arrhythmia. Pulmonary valve replacement (PVR) can alleviate this burden. As a predictor of ventricular arrhythmia, QRS duration remains a strong parameter in this decision. We performed a retrospective analysis of all PVR patients between 2005 and 2018, studying the time evolution of electrocardiographic parameters before and after PVR through linear mixed model analysis. 42 TOF patients underwent PVR. The median timespan between primary repair and PVR was 18 years (IQR 13-30). The indication for PVR was primarily based on the association of exercise intolerance (67%) and significant RV dilation on cMRI (median RVEDVi 161 ml/m2 IQR 133-181). Median QRS length was 155 ms (IQR 138-164), 4 (10%) patients had a QRS > 180 ms. QRS duration increased significantly before PVR, but barely showed regression after PVR. Changes of QRS duration after PVR were independent of RV dilation. In conclusion, when the decision for PVR in TOF patients is primarily based on RV volume and/or function threshold, QRS duration > 180 ms is rarely observed. In contrast with the significant increase of QRS duration before PVR, QRS length regression appears to be independent of the extent of RV dilation or QRS > 160 ms. Considering that the decision for PVR is based on mechanical RV characteristics, the utility of serial follow-up of QRS duration in contemporary operated TOF patients becomes questionable in absence of clinical arguments for ventricular arrhythmia.

Assessing Left Ventricular Early Diastolic Velocities With Tissue Doppler and Speckle Tracking by Transesophageal and Transthoracic Echocardiography.

BACKGROUND: Assessing diastolic dysfunction is essential and should be part of every routine echocardiography examination. However, clinicians routinely observe lower mitral annular velocities by transesophageal echocardiography (TEE) under anesthesia than described by awake transthoracic echocardiography (TTE). It would be important to know whether this difference persists under constant loading conditions. We hypothesized that mean early diastolic mitral annular velocity, measured by tissue Doppler imaging (TDI, JOURNAL/asag/04.03/00000539-202105000-00029/inline-graphic1/v/2021-04-15T211206Z/r/image-tiff) would be different in the midesophageal 4-chamber (ME 4Ch) than in the apical 4-chamber (AP 4Ch) view under unchanged or constant loading conditions. Secondarily we examined (1) JOURNAL/asag/04.03/00000539-202105000-00029/inline-graphic2/v/2021-04-15T211206Z/r/image-tiff in an alternative transesophageal view with presumed superior Doppler beam alignment, the deep transgastric view (DTG), compared to those in the AP 4Ch, and (2) early diastolic speckle tracking-based strain rate (JOURNAL/asag/04.03/00000539-202105000-00029/inline-graphic3/v/2021-04-15T211206Z/r/image-tiff), in the ME 4Ch and in the AP 4Ch. METHODS: Twenty-five consecutive adult patients undergoing on-pump cardiac surgery from February 2017 to July 2017 were included. Both TTE and TEE measurements were obtained under anesthesia in a randomized order in the AP 4Ch, ME 4Ch, and DTG views. Within-patient average values were compared by paired t tests with a Bonferroni adjustment. Box plots, correlation, and agreement by Bland-Altman were examined for all 3 comparisons. A second echocardiographer independently acquired and analyzed images; images were reanalyzed after 4 weeks. Image quality and reproducibility were also reported. RESULTS: Averaged JOURNAL/asag/04.03/00000539-202105000-00029/inline-graphic4/v/2021-04-15T211206Z/r/image-tiff measurements were lower in the ME 4Ch than in the AP 4Ch (6.6 ± 1.7 cm/s vs 7.0 ± 1.5 cm, P = .028; within-patient difference mean ± standard deviation: 0.6 ± 1.2 cm/s). An alternative TEE view for JOURNAL/asag/04.03/00000539-202105000-00029/inline-graphic5/v/2021-04-15T211206Z/r/image-tiff, the DTG, also exhibited lower mean values (6.0 ± 1.6 cm/s, P = .006; within-patient difference mean ± standard deviation: 1.1 ± 1.8 cm/s). JOURNAL/asag/04.03/00000539-202105000-00029/inline-graphic6/v/2021-04-15T211206Z/r/image-tiff strain rate showed a low degree of bias, but greater variability (ME 4Ch: 0.87 ± 0.32%/s vs AP 4Ch: 0.73 ± 0.18%/s, P = .078; within-patient difference mean ± standard deviation: -0.1 ± 0.2%/s). CONCLUSIONS: This study confirms that TEE modestly underestimates JOURNAL/asag/04.03/00000539-202105000-00029/inline-graphic7/v/2021-04-15T211206Z/r/image-tiff but not to a clinically relevant extent. While JOURNAL/asag/04.03/00000539-202105000-00029/inline-graphic8/v/2021-04-15T211206Z/r/image-tiff in the DTG is not a promising alternative, the future role for speckle tracking-based early diastolic strain rate is unknown.

ACARPA, a rare case of ALCAPA.

An anomalous circumflex coronary artery arising from the right pulmonary artery is very rare. Clinical presentation varies from absence of symptoms to arrhythmia and sudden cardiac death. Since prevalence is very low, no definite therapy has been delineated yet. A 19-year-old patient, previously treated for a vascular ring and mitral valve stenosis, was diagnosed with this anomaly through echocardiography revealing collateral coronary flow, with confirmation of this coronary anomaly on subsequent computed tomography examination. To alleviate the burden for arrhythmia in this young patient, he was successfully treated with surgical reimplantation followed by an uneventful recovery.

Post hoc patient satisfaction with the choice of valve prosthesis for aortic valve replacement: results of a single-centre survey.

OBJECTIVES: Our goal was to examine post hoc patient satisfaction and the decision-making process of choosing a prosthesis for aortic valve replacement (AVR). METHODS: We surveyed 113 patients who were operated on for AVR at 60-70 years of age, including 74 patients with a mechanical valve (MECH) and 39 with a bioprosthesis (BIO). The study focused on quality of life and the decision pathway in relation to prosthesis choice and valve-related complications. Decisional conflict was defined as the post hoc uncertainty perceived by patients regarding their choice of prosthesis. RESULTS: The survey was performed at a median of 5.2 (3.2-8.1) years after the AVR. Patients with a biological valve were older (BIO: 68.4 years [66.2-69.4] vs MECH: 63.9 [61.9-66.7]; P < 0.001). Global post hoc satisfaction with prosthesis choice was high in both groups (MECH: 95.9%; BIO: 100%), and 85.1% (MECH) and 92.3% (BIO) of them would repeat their choice. Conflict about their decision was equal (MECH: 30.3%; BIO: 32.6%) for different reasons: MECH patients experienced more anticoagulation-related inconvenience (25.9% vs 0%), fear of bleeding (31.1% vs 0%) and prosthesis noise (26.2% vs 0%), whereas more BIO patients feared prosthesis failure (39.7% vs 17.4%) or reoperation (43.5% vs 18.1%). Active involvement in the decision (odds ratio 0.37, 95% confidence interval 0.16-0.85; P = 0.029) and adequate information about the prosthesis (odds ratio 0.34, 95% confidence interval 0.14-0.86; P = 0.020) decreased the risk of conflict about the decision. CONCLUSIONS: Although 30% of the responders showed a decisional conflict related to prosthesis-specific interferences, global patient satisfaction with the prosthesis choice for AVR is excellent. Increasing the patient's involvement in the prosthesis choice through shared accountability and improved information is recommended to decrease the choice-related uncertainty.
