Evaluation of metabolic equivalents of task (METs) in the preoperative assessment in aortic repair.

BACKGROUND: Reliable prediction of the preoperative risk is of crucial importance for patients undergoing aortic repair. In this retrospective cohort study, we evaluated the metabolic equivalent of task (MET) in the preoperative risk assessment with clinical outcome in a cohort of consecutive patients. METHODS: Retrospective analysis of prospectively collected data in a single center unit of 296 patients undergoing open or endovascular aortic repair from 2009 to 2016. The patients were divided into four anatomic main groups (infrarenal (endo: n = 94; open: n = 88), juxta- and para-renal (open n = 84), thoraco-abdominal (open n = 13) and thoracic (endo: n = 11; open: n = 6). Out of these, 276 patients had a preoperative statement of their functional capacity in metabolic units and were evaluated concerning their postoperative outcome including survival, in-hospital mortality, postoperative complications, myocardial infarction and stroke, and the need of later cardiovascular interventions. RESULTS: The median follow-up of the cohort was 10.8 months. Patients with < 4MET had a higher incidence of diabetes mellitus (p = 0.0002), peripheral arterial disease (p < 0.0001), history of smoking (p = 0.003), obesity (p = 0.03) and chronic obstructive pulmonary disease (p = 0.05). Overall in-hospital mortality was 4.4% (13 patients). There was no significant difference in the survival between patients with a functional capacity of more than 4 MET (220 patients, mean survival: 74.5 months) and patients with less than 4 MET (56 patients, mean survival: 65.4 months) (p = 0.64). The mean survival of the infrarenal cohort (n = 169) was 74.3 months with no significant differences between both MET groups (> 4 MET: 131 patients, mean survival 75.5 months; < 4 MET: 38 patients, mean survival 63.6 months. p = 0.35). The subgroup after open surgical technique with less than 4 MET had the lowest mean survival of 38.8 months. In 46 patients with > 4MET (20.9%) perioperative complications occurred compared to the group with < 4MET with 18 patients (32.1%) (p = 0.075). There were no significant differences in both groups in the late cardiovascular interventions (p = 0.91) and major events including stroke and myocardial infarction (p = 0.4) monitored during the follow up period. The risk to miss a potential need for cardiac optimization in patients > 4MET was 7%. CONCLUSION: The functional preoperative evaluation by MET in patients undergoing aortic surgery is a useful surrogate marker of perioperative performance but cannot be seen as a substitute for preoperative cardiopulmonary testing in selected individuals.

Improved outcomes of elderly patients treated with drug-eluting versus bare metal stents in large coronary arteries: results from the BAsel Stent Kosten-Effektivitäts Trial PROspective Validation Examination randomized trial.

BACKGROUND: Drug-eluting stents (DES) improve outcomes in elderly patients with small coronary artery disease compared with bare-metal stents (BMS), but randomized data in elderly patients in need of large coronary stents are not available. METHODS: Planned secondary analysis of patients ≥75 years recruited to the "BASKET-PROVE" trial, in which 2,314 patients undergoing percutaneous coronary intervention for large (≥3.0 mm) native vessel disease were randomized 2:1 to DES (everolimus- vs sirolimus-eluting stents 1:1) versus BMS. All patients received 12 months of dual antiplatelet therapy. The primary end point was a composite of cardiac death or nonfatal myocardial infarction at 2 years. RESULTS: Comparison of DES versus BMS among 405 patients ≥75 years showed significantly lower rates of the primary end point for DES (5.0% vs 11.6%; hazard ration (HR) 0.64 [0.44-0.91]; P = .014). Rates of nonfatal myocardial infarction (1.2% vs 5.5%, hazard ration (HR) 0.44 [0.21-0.83]; P = .009), all-cause death (7.4% vs 14.4%; HR 0.7 [0.51-0.95]; P = .02), and target vessel revascularization (TVR) (2.3% vs 6.2%; HR 0.59 [0.34-0.99]; P = .046) were also lower, whereas stent thrombosis and bleeding rates were similar. In contrast, among patients <75 years (n = 1,909), the only significant benefit of DES was a reduced rate of TVR (4.0% vs 8.7%, HR 0.66 [0.55-0.80]; P < .0001). CONCLUSIONS: In patients ≥75 years requiring large (≥3.0 mm) coronary stents, use of DES was beneficial compared with BMS and reduced the rate of ischemic events, mortality, and TVR. These data suggest that DES should be preferred over BMS in elderly patients.

Atlas of genetics and cytogenetics in oncology and haematology in 2013.

The Atlas of Genetics and Cytogenetics in Oncology and Haematology (http://AtlasGeneticsOncology.org) is a peer-reviewed internet journal/encyclopaedia/database focused on genes implicated in cancer, cytogenetics and clinical entities in cancer and cancer-prone hereditary diseases. The main goal of the Atlas is to provide review articles that describe complementary topics, namely, genes, genetic abnormalities, histopathology, clinical diagnoses and a large iconography. This description, which was historically based on karyotypic abnormalities and in situ hybridization (fluorescence in situ hybridization) techniques, now benefits from comparative genomic hybridization and massive sequencing, uncovering a tremendous amount of genetic rearrangements. As the Atlas combines different types of information (genes, genetic abnormalities, histopathology, clinical diagnoses and external links), its content is currently unique. The Atlas is a cognitive tool for fundamental and clinical research and has developed into an encyclopaedic work. In clinical practice, it contributes to the cytogenetic diagnosis and may guide treatment decision making, particularly regarding rare diseases (because they are numerous and are frequently encountered). Readers as well as the authors of the Atlas are researchers and/or clinicians.

Interaction between pulmonary hypertension and diastolic dysfunction in an elderly heart failure population.

BACKGROUND: Pulmonary hypertension due to left heart disease is very common. Our aim was to investigate the relationship of the severity of left ventricular diastolic dysfunction with precapillary and postcapillary pulmonary hypertension (PH) in an elderly heart failure (HF) population. METHODS AND RESULTS: A post hoc analysis of the Trial of Intensified Medical Therapy in Elderly Patients With Congestive Heart Failure data was done. Baseline transthoracic echocardiography was used to categorize diastolic function, estimate pulmonary artery pressure and pulmonary capillary wedge pressure, and calculate the transpulmonary pressure gradient (TPG). Among 392 HF patients, PH was present in 31% of patients with grade 1, in 37% of patients with grade 2, and in 65% of patients with grade 3 diastolic dysfunction; 54% of all HF patients with PH had a TPG >12 mm Hg, suggesting not only a postcapillary but also an additional precapillary component of PH. Survival was not related to the severity of diastolic dysfunction, but was worse in patients with PH (hazard ratio 1.63, 95% confidence interval 1.07-2.51; P = .024). CONCLUSIONS: Our data indicate that HF patients with even mild diastolic dysfunction often have PH. Echocardiographic assessment suggest that the presence of PH might not simply be due to increased PCWP, but in part due to a precapillary component.

Does anonymous sperm donation increase the risk for unions between relatives and the incidence of autosomal recessive diseases due to consanguinity?

In France gamete donation and notably sperm donation are anonymous. It has been claimed that anonymous artificial insemination by donor (AID) could highly contribute to an increase in the level of consanguinity and the incidence of autosomal recessive diseases, due to the unions between offspring of anonymous donors, unaware of their biological kinship, with the special case of unions between half-siblings. The actual incidence of consanguinity due to AID was compared with that resulting from the two other main sources of consanguinity and recessive diseases, i.e. voluntary unions between related individuals or inadvertent unions between the offspring of a common unknown male ancestor (false paternity). From these data, we estimated that expected unions in France between half sibs per year are 0.12 between offspring of sperm donors (1.2 every 10 years) and 0.5 between offspring of common male ancestors through false paternity (5 every 10 years). More generally, the inadvertent unions between false paternity offspring are roughly four times more frequent than those resulting from anonymous AID. We estimated that in the future, when AID has been in practice for several generations, out the 820 000 annual births in France, respectively, 6 and 25 births will be consanguineous through an unknown common ancestor related to anonymous AID and to a false paternity, both of which are negligible when compared with the 1256 children born from first-degree cousins. About 672 children per year are born with a recessive genetic disease due to the panmictic risk and additional affected cases due to consanguinity would be 34.54 for first-cousin offspring, 0.33 for offspring of individuals related due to false paternity and 0.079 for offspring of individuals related due to anonymous AID. Anonymous AID would therefore be responsible for 0.46% of consanguineous births and for 0.01% of recessive diseases. Therefore, the effect of anonymous AID on half-sibling unions, consanguinity and recessive disease incidence can be regarded as marginal.

Severe multifocal coronary artery spasms after cessation of vasodilators in a patient with a spontaneous coronary artery dissection: a case report.

Background: Vasospastic angina (VSA) and spontaneous coronary artery dissection (SCAD) are challenging causes of non-atherosclerotic acute coronary syndromes (ACS). Here, we report a unique ACS case with coexisting VSA and SCAD, highlighting specific strategies in diagnosis and management of these poorly studied conditions. Case summary: A woman in her mid-60s with a history of suspected microvascular angina and no atherosclerosis in a previously performed coronary computed tomography angiography presented with worsening chest pain. Invasive coronary angiography revealed a focal SCAD with a resulting high-degree stenosis of the right coronary artery. Shortly after successful percutaneous coronary intervention with stent implantation and stopping her previous vasodilator therapy with nitroglycerine and molsidomine, the patient developed recurrent anterior non-ST-segment elevation myocardial infarction. Surprisingly, repeat coronary angiography revealed severe multifocal coronary artery spasms that were successfully treated with intracoronary nitroglycerine. Vasospastic angina was subsequently managed with diltiazem, molsidomine, and nitrates. Discussion: Our report underscores the challenges in diagnosing and managing SCAD and VSA in ACS. The possible interplay between SCAD and VSA highlights the need for careful vasodilator therapy management, as seen in our patient, where therapy discontinuation led to severe multifocal VSA. This emphasizes the need for a comprehensive approach for optimal outcomes in complex ACS cases.

[Update Valvular Heart Disease: Heart Team Decision-Making Based on Patient Examples]. / Update valvuläre Herzkrankheiten: Entscheidungen im interdisziplinären Herzteam anhand von Beispielen.

INTRODUCTION: In Europe, mitral regurgitation and aortic stenosis are the most common valve lesions requiring interventions. In advanced stages, these valve pathologies affect patients' quality of life and prognosis. The prevalence of mitral regurgitation and aortic stenosis is increasing with age. In view of an aging population and the comorbidities associated with age, these valve defects represent an increasing challenge to health care providers. Nowadays, surgical as well as catheter-based treatment options are available to treat affected patients. Therapeutic strategies suitable to the individual patient should be discussed in interdisciplinary heart teams. The aim of the present article is to give an overview of possible guideline-conform heart team decisions based on patient examples.

Association of chocolate consumption with neurological and cardiovascular outcomes in atrial fibrillation: data from two Swiss atrial fibrillation cohort studies (Swiss-AF and BEAT-AF).

AIM: To assess the associations of chocolate consumption with neurocognitive function, brain lesions on magnetic resonance imaging (MRI), and cardiovascular outcome in patients with atrial fibrillation (AF). METHODS: We analysed data from patients of two prospective multicentre Swiss atrial fibrillation cohort studies (Swiss-AF) and (BEAT-AF). Assessments of MRI findings and neurocognitive function were performed only in the Swiss-AF population (in 1727 of 2415 patients [71.5%] with a complete data set), as patients enrolled in BEAT-AF were not systematically evaluated for these outcomes. Otherwise, the two cohorts had an equivalent set of clinical assessments. Clinical outcome analysis was performed in 3931 patients of both cohorts. Chocolate consumption was assessed by questionnaire. Patients were categorised as no/low chocolate consumption (No/Low-Ch) ≤1 servings/week, moderate chocolate consumption (Mod-Ch) >1-6 servings/week, and high chocolate consumption (High-Ch) >6 servings/week, respectively. Brain lesions were evaluated by MRI. Assessment of cognitive function was performed by neurocognitive functional testing and included global cognition measurement with a cognitive construct score. Cerebral MRI and cognition were evaluated at baseline. Cross-sectional associations between chocolate consumption and MRI findings were analysed by multivariate logistic regression models and associations with neurocognitive function by multivariate linear regression models. Clinical outcome events during follow-up were recorded and assessed by a clinical event committee. The associations between chocolate consumption and clinical outcomes were evaluated by Cox regression models. The median follow-up time was 6 years. RESULTS: Chocolate consumption was not associated with prevalence or volume of vascular brain lesions on MRI, nor major adverse cardiac events (ischaemic stroke, myocardial infarction, cardiovascular death). However, No/Low-Ch was independently associated with a lower cognitive construct score compared to Mod-Ch (No/Low-Ch vs. Mod-Ch: coeff. -0.05, 95% CI -0.10-0), whereas other neurocognitive function tests were not independently associated with chocolate consumption categories. In addition, there was a higher risk of heart failure hospitalisation (No/Low-Ch vs. Mod-Ch: HR 1.24, 95% CI 1.01-1.52) and of all-cause mortality (No/Low-Ch vs. Mod-Ch: HR 1.29, 95% CI 1.06-1.58) in No/Low-Ch compared to Mod-Ch. No significant associations with the evaluated outcomes were observed when High-Ch was compared to Mod-Ch. CONCLUSION: While chocolate consumption was not associated with MRI findings and major adverse cardiac events in an atrial fibrillation population, No/Low-Ch was associated with a lower cognitive construct score, higher risk of heart failure hospitalisation and increased all-cause mortality compared to Mod-Ch.

Does the prognostic value of dobutamine stress echocardiography differ among different age groups?

BACKGROUND: Age is associated with reduced exercise capacity and greater prevalence of coronary artery disease. Whether the prognostic information obtained from dobutamine stress echocardiography (DSE), a stress test commonly used for patients unable to perform an exercise test, provides differential information based on age is not well known. METHODS: We studied 6,655 consecutive patients referred for DSE. Patients were divided into 3 age groups: (1) <60 years (n = 1,389), (2) 60 to 74 years (n = 2,978), and (3) ≥75 years (n = 2,288). Mean follow-up was 5.5 ± 2.8 years. End points included all-cause mortality and cardiac events, including myocardial infarction and late (>3 months) coronary revascularization. RESULTS: Peak stress wall motion score index was an independent predictor of cardiac events in all age groups (<60 years: hazard ratio [HR] 1.14, P = .02; 60-74 years: HR 1.70, P < .0001; ≥75 years: HR 1.10, P = .006). In patients ≥75 years, peak wall motion score index (HR 1.10, P < .0001) and abnormal left ventricular end-systolic volume response (HR 1.25, P = .03) were independent predictors of death. In patients aged 60 to 74 years, abnormal left ventricular end-systolic volume response (HR 1.43, P = .0003) was independently related to death, whereas in patients <60 years, the echocardiographic data assessed during stress were not a predictor. CONCLUSIONS: Dobutamine stress echocardiography provided independent information predictive of cardiac events among all age groups and death in patients ≥60 years. However, among patients <60 years, stress-induced echocardiographic abnormalities were not independently associated with mortality. Comorbidities, which have precluded exercise testing, may be most relevant in predicting mortality in patients <60 years undergoing DSE.

Second diastolic pulmonary venous flow and isolated late diastolic mitral valve regurgitation in first-degree atrioventricular block.

The authors report the case of a 77-year-old male patient with sinus rhythm and a first-degree atrioventricular (AV) block who was referred for echocardiographic follow-up 18 years after aortic valve replacement. Left ventricular systolic function as well as the function of the aortic prosthesis was normal. Systolic mitral regurgitation (MR) was virtually absent, but isolated late diastolic MR was detected by colour Doppler imaging. Coincidental to the occurrence of diastolic MR, a second late diastolic forward flow in the pulmonary veins was observed. Therefore, during the prolonged left atrial relaxation caused by first-degree AV block, the left atrial pressure drops below the pressure in both adjacent chambers in late diastole, resulting in both late diastolic MR and a second diastolic pulmonary venous forward flow.

Dexamethasone but not tadalafil improves exercise capacity in adults prone to high-altitude pulmonary edema.

RATIONALE: Whether pulmonary hypertension at high altitude limits exercise capacity remains uncertain. OBJECTIVES: To gain further insight into the pathophysiology of hypoxia induced pulmonary hypertension and the resulting reduction in exercise capacity, we investigated if the reduction in hypoxic pulmonary vasoconstrictive response with corticosteroids or phosphodiesterase-5 inhibition improves exercise capacity. METHODS: A cardiopulmonary exercise test and echocardiography to estimate systolic pulmonary artery pressure were performed in 23 subjects with previous history of high altitude pulmonary edema, known to be associated with enhanced hypoxic vasoconstriction. Subjects were randomized to dexamethasone 8 mg twice a day, tadalafil 10 mg twice a day, or placebo (double-blinded), starting the day before ascent. MEASUREMENTS AND MAIN RESULTS: Measurements were performed at low and high (i.e., 4,559 m) altitude. Altitude exposure decreased maximum oxygen uptake and oxygen saturation, increased pulmonary artery pressure, and altered oxygen uptake kinetics. Compared with placebo, dexamethasone improved maximum oxygen uptake (% predicted 74 +/- 13%; tadalafil 63 +/- 13%, placebo 61 +/- 11%; P < 0.05), oxygen kinetics (mean response time 41 +/- 13 s; tadalafil 46 +/- 6 s, placebo 45 +/- 10 s; P < 0.05), and reduced the ventilatory equivalent for CO(2) (42 +/- 4; tadalafil 49 +/- 4, placebo 50 +/- 5; P < 0.01). Peak oxygen saturation did not differ significantly between the three groups (dexamethasone 66 +/- 7%, placebo 62 +/- 7%, tadalafil 69 +/- 5%; P = 0.08). During echocardiography at low-intensity exercise (40% of peak power), dexamethasone compared with placebo resulted in lower pulmonary artery pressure (47 +/- 9 mm Hg; tadalafil 57 +/- 11 mm Hg, placebo 68 +/- 23 mm Hg; P = 0.05) and higher oxygen saturation (74 +/- 7%; tadalafil 67 +/- 3%, placebo 61 +/- 20; P < 0.02). CONCLUSIONS: Corticosteroids, but not phosphodiesterase-5 inhibition, partially prevented the limitation of exercise capacity in subjects with intense hypoxic pulmonary vasoconstriction at high altitude.

First in Switzerland: concomitant off-pump transapical transcatheter aortic valve implantation and mitral valve reconstruction with the NeoChord system.

Old and polymorbid patients with multivalvular heart disease comprise a special patient group, with high perioperative morbidity and mortality. We report the case of an 80-year-old, female, polymorbid patient with severe mitral valve regurgitation and moderate to severe aortic valve stenosis. This is the first case in Switzerland of a concomitant transapical transcatheter aortic valve implantation and mitral valve reconstruction with the NeoChord system, on a beating heart and with a minimally invasive approach through a left anterolateral thoracotomy. This case emphasises the possibility of a low-risk minimally invasive procedure on this high-risk patient-group and shows the importance of interdisciplinary discussion and cooperation in heart teams for optimal patient treatment.

Gender differences in patient and system delay for primary percutaneous coronary intervention: current trends in a Swiss ST-segment elevation myocardial infarction population.

BACKGROUND: Women with ST-segment elevation myocardial infarction (STEMI) experience greater delays for percutaneous coronary intervention-facilitated reperfusion than men. Whether women and men benefit equally from current strategies to reduce ischaemic time and whether there are gender differences in factors determining delays is unclear. METHODS: Patient delay (symptom onset to first medical contact) and system delay (first medical contact to percutaneous coronary intervention-facilitated reperfusion) were compared between women ( n=967) and men ( n=3393) in a Swiss STEMI treatment network. Trends from 2000 to 2016 were analysed, with additional comparisons between three time periods (2000-2005, 2006-2011 and 2012-2016). Factors predicting delays and hospital mortality were determined by multivariate regression modelling. RESULTS: Female gender was independently associated with greater patient delay ( P=0.02 vs. men), accounting for a 12% greater total ischaemic time among women in 2012-2016 (median 215 vs. 192 minutes, P<0.001 vs. men). From 2000-2005 to 2012-2016, median system delay was reduced by 18 and 25 minutes in women and men, respectively ( P<0.0001 for trend, P=n.s. for gender difference). Total occlusion of the culprit artery, stent thrombosis, a Killip class of 3 or greater, and presentation during off-hours predicted delays in men, but not in women. A Killip class of 3 or greater and age, but not gender or delays, were independently associated with hospital mortality. CONCLUSIONS: STEMI-related ischaemic time in women remains greater than in men due to persistently greater patient delays. In contrast to men, clinical signs of ongoing chest discomfort do not predict delays in women, suggesting that female STEMI patients are less likely to attribute symptoms to a condition requiring urgent treatment.

High-resolution array comparative genomic hybridization analysis of human bronchial and salivary adenoid cystic carcinoma.

Adenoid cystic carcinoma (ACC) is a rare but distinctive tumor. Oligonucleotide array comparative genomic hybridization has been applied for cataloging genomic copy number alterations (CNAs) in 17 frozen salivary or bronchial tumors. Only four whole chromosome CNAs were found, and most cases had 2-4 segmental CNAs. No high level amplification was observed. There were recurrent gains at 7p15.2, 17q21-25, and 22q11-13, and recurrent losses at 1p35, 6q22-25, 8q12-13, 9p21, 12q12-13, and 17p11-13. The minimal region of gain at 7p15.2 contained the HOXA cluster. The minimal common regions of deletions contained the CDKN2A/CDKN2B, TP53, and LIMA1 tumor suppressor genes. The recurrent deletion at 8q12.3-13.1 contained no straightforward tumor suppressor gene, but the MIRN124A2 microRNA gene, whose product regulates MMP2 and CDK6. Among unique CNAs, gains harbored CCND1, KIT/PDGFRA/KDR, MDM2, and JAK2. The CNAs involving CCND1, MDM2, KIT, CDKN2A/2B, and TP53 were validated by FISH and/or multiplex ligation-dependent probe amplification. Although most tumors overexpressed cyclin D1 compared with surrounding glands, the only case to overexpress MDM2 had the corresponding CNA. In conclusion, our report suggests that ACC is characterized by a relatively low level of structural complexity. Array CGH and immunohistochemical data implicate MDM2 as the oncogene targeted at 12q15. The gain at 4q12 warrants further exploration as it contains a cluster of receptor kinase genes (KIT/PDGFRA/KDR), whose products can be responsive to specific therapies.

Cost-effectiveness of drug-eluting stents in patients at high or low risk of major cardiac events in the Basel Stent KostenEffektivitäts Trial (BASKET): an 18-month analysis.

BACKGROUND: Our aim was to determine whether drug-eluting stents are good value for money in long-term, everyday practice. METHODS: We did an 18-month cost-effectiveness analysis of the Basel Stent KostenEffektivitäts Trial (BASKET), which randomised 826 patients 2:1 to drug-eluting stents (n=545) or to bare-metal stents (281). We used non-parametric bootstrap techniques to determine incremental cost-effectiveness ratios (ICERs) of drug-eluting versus bare-metal stents, to compare low-risk (> or =3.0 mm stents in native vessels; n=558, 68%) and high-risk patients (<3.0 mm stents/bypass graft stenting; n=268, 32%), and to do sensitivity analyses by altering costs and event rates in the whole study sample and in predefined subgroups. Quality-adjusted life-years (QALYs) were assessed by EQ-5D questionnaire (available in 703/826 patients). FINDINGS: Overall costs were higher for patients with drug-eluting stents than in those with bare-metal stents (11,808 euros [SD 400] per patient with drug-eluting stents and 10,450 euros [592] per patient with bare-metal stents, mean difference 1358 euros [717], p<0.0001), due to higher stent costs. We calculated an ICER of 64,732 euros to prevent one major adverse cardiac event, and of 40,467 euros per QALY gained. Stent costs, number of events, and QALYs affected ICERs most, but unrealistic alterations would have been required to achieve acceptable cost-effectiveness. In low-risk patients, the probability of drug-eluting stents achieving an arbitrary ICER of 10,000 euros or less to prevent one major adverse cardiac event was 0.016; by contrast, it was 0.874 in high-risk patients. INTERPRETATION: If used in all patients, drug-eluting stents are not good value for money, even if prices were substantially reduced. Drug-eluting stents are cost effective in patients needing small vessel or bypass graft stenting, but not in those who require large native vessel stenting.

Role of hepatic resection for patients with carcinoid heart disease.

OBJECTIVE: To evaluate the effects of resection of hepatic carcinoid metastases on progression and prognosis of carcinoid heart disease. PATIENTS AND METHODS: From our database of 265 consecutive patients diagnosed as having carcinoid heart disease from January 1, 1980, through December 31, 2005, we calculated survival from first diagnosis of cardiac involvement. Hepatic resection during follow-up was entered as a time-dependent covariable in a multivariable analysis. In patients with serial echocardiograms more than 1 year apart without intervening cardiac surgery, a previously validated cardiac severity score was calculated. A score increase that exceeded 25% was considered relevant progression. RESULTS: Hepatic resection was performed in 31 patients (12%) during follow-up. Five-year survival was significantly higher in these patients (86.5%; 95% confidence interval [CI], 73.5%-100.0%) than in patients without hepatic resection (29.0%; 95% CI, 23.3%-36.1%; univariable hazard ratio for hepatic resection, 0.25; 95% CI 0.12-0.53; P<.001). Hepatic resection remained strongly associated with improved prognosis in multivariable analysis (hazard ratio, 0.31; 95% CI, 0.14-0.66; P=.003). Among 77 patients (29%) with serial echocardiograms, 10 (13%) underwent hepatic resection during follow-up; resection was independently associated with decreased risk of cardiac progression (odds ratio, 0.29; 95% CI, 0.06-0.75; P=.03). CONCLUSION: Despite the limitations of this retrospective nonrandomized study, our data suggest that patients with carcinoid heart disease who undergo hepatic resection have decreased cardiac progression and improved prognosis. Eligible patients should be considered for hepatic surgery.

Left ventricular non-compaction: is it really isolated?

Isolated ventricular non-compaction (IVNC) is a genetically determined cardiac disease mainly involving the left ventricle. Since the first description and recognition of IVNC as a distinct cardiomyopathy, many cases have been described. However, the associated right-sided cardiac anomalies are unusual. Two cases of IVNC showing associated right-sided pathology on transthoracic echocardiography are presented.

Screening For Pulmonary Hypertension With Multidetector Computed Tomography Among Patients With Severe Aortic Stenosis Undergoing Transcatheter Aortic Valve Implantation.

Aim: To assess the accuracy of multi-detector computed tomography (MDCT) derived pulmonary vessel measurements in predicting pulmonary hypertension (PH) among patients with severe symptomatic aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI). Background: PH is common among patients with severe AS undergoing TAVI and is associated with adverse outcomes. MDCT is the imaging modality of choice to assess anatomical dimensions among patients selected for TAVI. Methods: One hundred and thirty-nine patients with severe AS undergoing TAVI with both CT scans and right heart catheterizations (RHC) were included. CT diameters of the main pulmonary artery (MPA), right (RPA) and left (LPA), and ascending aorta (AA) were measured. The relationship between CT measurements and PA pressures assessing using RHC was tested with linear regression. Results: The CT derived ratio of the diameter of the MPA to the diameter of the AA (PA/AAratio) correlated best with mean PA pressure (R2 = 0.48) and PA systolic pressure (R2 = 0.50). Receiver operating characteristic curve analysis showed that the PA/AAratio is a moderate predictor of PH (AUC 0.74, 95% CI 0.65-0.83, p < 0.0001) and that the optimal cut off point is 0.80 (sensitivity 56%, specificity 88%, positive predictive value 95.5%, negative predictive value 30.6% for PH). Conclusions: Elderly patients with severe AS and PA/AAratio values ≥ 0.80 on MDCT are more likely to have PH but PH cannot be reliably excluded among such patients with lower PA/AAratio values.
