BACKGROUND: Patients with left bundle branch block (LBBB) often respond to cardiac resynchronization therapy (CRT) with left ventricular ejection fraction (LVEF) improvement. Guideline-directed medical therapy (GDMT), not CRT, is first-line therapy for patients with reduced LVEF with LBBB. However, there are little data on how patients with reduced LVEF and LBBB respond to GDMT. OBJECTIVES: This study examined patients with cardiomyopathy and sought to assess rates of LVEF improvement for patients with LBBB compared to other QRS morphologies...

OBJECTIVES: This study sought to examine the safety and performance of contemporary transcatheter aortic valve replacement (TAVR) in an exclusive all-women TAVR population, and to further investigate the potential impact of female sex-specific characteristics on composite 1-year clinical outcomes. BACKGROUND: Women comprise ≥50% patients undergoing TAVR. Several data have shown the noninferiority of TAVR compared with surgical aortic valve replacement for symptomatic significant aortic stenosis, but no study so far has been specifically powered to detect differences by sex...

BACKGROUND Overall, life expectancy at the age of 80 has significantly increased in the industrialized world and the proportion of this age class undergoing cardiac surgery has also grown. In this context, we have analyzed a contemporary series of octogenarians undergoing mitral valve surgery at our institution. MATERIAL AND METHODS We performed a retrospective analysis of 138 consecutive octogenarians receiving mitral valve surgery between January 2006 and April 2017. Preoperative comorbidities, early mortality, postoperative clinical course, and predictors of mortality were examined...

OBJECTIVES: The del Nido cardioplegia solution has been used extensively in congenital heart surgery for more than 20 years and more recently for adults. This randomized controlled trial examined whether expanding this technique to adult cardiac surgery confers benefits in surgical workflow and clinical outcome compared with blood-based cardioplegia. METHODS: Adult first-time coronary artery bypass grafting (CABG), valve, or CABG/valve surgery patients requiring cardiopulmonary bypass (CPB) were randomized to del Nido cardioplegia (n = 48) or whole blood cardioplegia (n = 41)...

BACKGROUND: Recent reports of leaflet abnormalities (detected using advanced imaging) have raised questions regarding transcatheter aortic valve replacement (TAVR) durability. We sought to determine the incidence of valve hemodynamic deterioration (VHD) and its association with cardiovascular outcomes. METHODS AND RESULTS: Consecutive cases with paired postimplant and follow-up echocardiograms from November 2011 to March 2015 in the STS/ACC TVT Registry were allocated into 2 overlapping cohorts: early (paired echocardiograms at 0 and 30 days) and late (paired echocardiograms at 30 days and 1 year)...

BACKGROUND: Balloon aortic valvuloplasty (BAV) is often utilized as a bridge prior to surgical or transcatheter aortic valve replacement. Chronic kidney disease (CKD) is commonly present in patients with aortic stenosis, however, its association with outcomes following BAV has not been well studied. Accordingly, we sought to assess the impact of CKD on mortality in adults undergoing BAV. METHODS: The Nationwide Inpatient Sample was screened for hospitalizations involving adults undergoing BAV from 2006 to 2012...

Physical training, psychosocial intervention, nutrition counselling and optimisation of secondary preventive medication to reduce morbidity and mortality of the disease as well as the reintegration into social life and return to work are equivalent goals of cardiac rehabilitation. This requires multifactorial intervention by a multidisciplinary team. In Germany, cardiac rehabilitation starting early after an index event could demonstrate a significant reduction of total mortality, myocardial infarction and hospitalisation during a follow-up of 1-2 years in 5 controlled cohort studies including 12 556 patients after myocardial infarction and CABG surgery...

BACKGROUND: Metastatic cardiac tumors may cause different symptoms including angina, symptoms of heart failure and/or arrhythmia. In patients with concomitant coronary artery disease, it may be difficult to distinguish between angina caused by metastases to the heart, for example, by stealing perfusion from the coronary arteries, and angina caused by coronary stenosis. Identifying the origin of the symptoms is, however, essential for designing appropriate surgical strategies. CASE PRESENTATION: A 69-year-old male with multifocal recurrence of a hepatocellular carcinoma (HCC) presented with increasing ventricular arrhythmia and angina several weeks after posterior myocardial infarction and PCI of the RCA culprit lesion during which two further lesions present in the distal RCX and a posterolateral branch, and a chronically occluded LAD had not been addressed...

Heart failure is accompanied by extracellular matrix (ECM) remodelling, often leading to cardiac fibrosis. In the present study we explored the significance of cartilage intermediate layer protein 1 (CILP1) as a novel mediator of cardiac ECM remodelling. Whole genome transcriptional analysis of human cardiac tissue samples revealed a strong association of CILP1 with many structural (e.g. COL1A2 r(2) = 0.83) and non-structural (e.g. TGFB3 r(2) = 0.75) ECM proteins. Gene enrichment analysis further underscored the involvement of CILP1 in human cardiac ECM remodelling and TGFβ signalling...

BACKGROUND: On-pump cardiac surgery provokes a predictable perioperative myocardial ischaemia-reperfusion injury which is associated with poor clinical outcomes. We determined the occurrence of time-of-the-day variation in perioperative myocardial injury in patients undergoing aortic valve replacement and its molecular mechanisms. METHODS: We studied the incidence of major adverse cardiac events in a prospective observational single-centre cohort study of patients with severe aortic stenosis and preserved left ventricular ejection fraction (>50%) who were referred to our cardiovascular surgery department at Lille University Hospital (Lille, France) for aortic valve replacement and underwent surgery in the morning or afternoon...

OBJECTIVES: Mitral valve (MV) repairs have been performed in paediatric patients with congenital MV stenosis. However, congenital MV stenosis lesions are a heterogeneous group of lesions, and their repair remains challenging. METHODS: From March 1999 to September 2014, MV repair was performed in 22 patients with congenital MV stenosis. The median age was 10.3 months (ranging from 22 days to 9.1 years), and the mean body weight was 7.9 ± 4.0 kg at the time of the operation...

BACKGROUND: Cardiac surgical units must balance trainee education with the duty to provide optimal patient care. This is particularly challenging with valvular surgery, given the lower volume and increased complexity of these procedures. The present meta-analysis was conducted to assess the impact of trainee operator status on clinical outcomes following valvular surgery. METHODS: Medline, Embase and CENTRAL databases were systematically searched for studies reporting clinical outcomes according to the training status of the primary operator (consultant or trainee)...

Objective Ischemic mitral regurgitation is a predictor of heart failure resulting in increased mortality in patients with chronic myocardial infarction. It is uncertain whether the presence of papillary muscle (PM) infarction contributes to the development of mitral regurgitation in patients with chronic myocardial infarction (MI). The aim of the present study was to assess the correlation of PM infarction depicted by MRI with mitral regurgitation and left ventricular function. Methods and Materials 48 patients with chronic MI and recent MRI and echocardiography were retrospectively included...

BACKGROUND: Data on transcatheter aortic valve replacement (TAVR) long-term clinical outcomes and hemodynamic performance of the self-expandable CoreValve (CV) and the balloon-expandable Edwards SAPIEN XT (ES) (Edwards Lifesciences, Irvine, California, USA) transcatheter heart valves (THV) are limited. Therefore, this study aimed to compare long-term clinical outcome data and hemodynamic performance of TAVR with either CV or ES. METHODS: We reviewed prospectively collected data of 171 patients treated with TAVR for severe aortic stenosis (AS) at our center between June 2007 and December 2010, with last follow-up contact in 2016...

BACKGROUND: Mutations in LMNA gene, encoding Lamin A/C, cause a diverse array of phenotypes, collectively referred to as laminopathies. The most common manifestation is dilated cardiomyopathy (DCM), occurring in conjunction with variable skeletal muscle involvement but without involvement of the coronary arteries. Much less commonly, LMNA mutations cause progeroid syndromes, whereby an early-onset coronary artery disease (CAD) is the hallmark of the disease. We report a hitherto unreported compound cardiac phenotype, dubbed as "non-syndromic cardiac progeria", in a young patient who carried a rare pathogenic variant in the LMNA gene and developed progressive degeneration of various cardiac structures, as seen in the elderly...

BACKGROUND: Mitral regurgitation in people without prior cardiac disease is considered a degenerative disease with no established risk factors for its prevention. We aimed to test the hypothesis that elevated systolic blood pressure (SBP) across its usual spectrum is associated with higher risk of mitral regurgitation. METHODS AND FINDINGS: We used linked electronic health records from the United Kingdom Clinical Practice Research Datalink (CPRD) from 1 January 1990 to 31 December 2015...

During outpatient cardiac rehabilitation after an acute coronary syndrome or after an episode of congestive heart failure, a careful, periodic evaluation of patients' clinical and hemodynamic status is essential. Simple and traditional cardiac auscultation could play a role in providing useful prognostic information.Reduced intensity of the first heart sound (S1), especially when associated with prolonged apical impulse and the appearance of added sounds, may help identify left ventricular (LV) dysfunction or conduction disturbances, sometimes associated with transient myocardial ischemia...
