#1
Julien I E Hoffman
Tetralogy of Fallot can be corrected with very low mortality at any age, even in neonates, but this does not necessarily mean that it should be corrected in the neonatal period. Although there are many advantages to early correction, a high proportion of these neonates have residual stenosis or pulmonary regurgitation that impairs ventricular function and may require further surgery or implantation of a pulmonary valve. Before we had the ability to correct this anomaly with low mortality in small children, a variety of palliative procedures had to be performed...

BACKGROUND: We aimed to identify the clinical and echocardiographic determinants of symptoms and their prognostic implications in patients with moderately dysfunctional bicuspid aortic valves (BAVs). METHODS: Among 1,019 subjects in the BAV registry treated in a single tertiary care center, the records of 127 patients (85 men, age 58±13 years) with moderately dysfunctional BAVs were comprehensively reviewed. The patients were divided into two groups based on symptom status: asymptomatic (n = 80) vs...

BACKGROUND & AIMS: Direct oral anticoagulant (DOAC) agents increase the risk of gastrointestinal (GI) bleeding. We investigated which DOAC had the most favorable GI safety profile and compared differences among these drugs in age-related risk of GI bleeding. METHODS: We conducted a retrospective, propensity-matched study using administrative claims data from the OptumLabs Data Warehouse of privately insured individuals and Medicare Advantage enrollees. We created 3 propensity-matched cohorts of patients with non-valve atrial fibrillation with incident exposure to dabigatran, rivaroxaban, or apixaban, from October 1, 2010 through February 28, 2015...

We assessed the effect of a transcatheter aortic valve replacement (TAVR) program and Heart Team concept on our approach to severe isolated symptomatic aortic stenosis (AS) with regard to surgical practice, patient selection, perioperative outcomes, 1-year survival, and AVR volume. TAVR program began in August 2011. Patients having isolated surgical AVR between January 2008 and August 2011, when the program began (n = 282, 42 months), were compared with those after the program began until February 2015 (n = 344, surgical AVR and n = 126, TAVR, 42 months)...

Aminoglycosides are a mainstay of treatment for enterococcal infective endocarditis. However, the benefit of adding aminoglycosides to cell wall-active agents after surgery is unclear. The aim of this study was to determine if adjunctive aminoglycoside treatment after surgery for enterococcal endocarditis leads to better outcomes. We included patients who underwent surgery for enterococcal endocarditis at our institution between July 2007 and July 2014. Treatment was defined as at least 1 dose of an aminoglycoside after surgery...

Infective endocarditis (IE) has historically caused significant morbidity and mortality. Valve surgery reduces systemic embolization and mortality, but the optimal timing is controversial. The EASE (Early Surgery Versus Conventional Treatment for Infective Endocarditis) trial, which employed strict inclusion and exclusion criteria, showed that early surgery could reduce the risk of embolic events for a subset of patients. The aim of the present study was to determine the proportion of adult IE patients seen in usual clinical practice at a single tertiary medical center that would meet EASE enrollment criteria...

BACKGROUND: Aortic valve replacement (AVR) is the treatment of choice in patients with severe symptomatic aortic stenosis (AS). Patients with a low left ventricular ejection fraction (LVEF) represent a challenge for evaluation and therapeutic decision. Dobutamine stress echocardiography (DSE) allows the distinction to be made between fixed low-flow/low-gradient (LF/LG) AS and pseudosevere AS. METHODS: Between 2001 and 2014 a retrospective analysis was conducted of patients who underwent DSE to investigate severe AS...

INTRODUCTION: Cardiac operations account for a large proportion of the blood transfusions given each year, leading to high costs and an increased risk to patient safety. Therefore, it is important to explore initiatives to reduce transfusion rates. This study aims to provide a benchmark for transfusion practice by inter-hospital comparison of transfusion rates, blood product use and costs related to patients undergoing coronary artery bypass grafting (CABG), valve surgery or combined CABG and valve surgery...

In literature, there are limited data comparing ischemic mitral regurgitation (I-MR) versus nonischemic MR regarding outcomes after percutaneous "edge-to-edge" repair. We aimed to describe the early and 12-month results after MitraClip device implantation regarding the 2 etiologies. From January 2011 to December 2012, the Transcatheter Valve Treatment Sentinel Pilot Registry included 452 patients with MR who underwent MitraClip procedure in 25 centers across Europe. The prevalent etiology was I-MR (235 patients, 52...

OBJECTIVE: Until now, no study established a morphometric evaluation of the truncal valve dysplasia and a description of its different presentation patterns. Thus, authors conducted an anatomopathological study describing the gross features and histological findings of the truncal valve. METHODS: 50 common arterial trunk (CAT) specimens were examined. The number of valvar leaflets was determined and valvar dysplasia was classified as absent, mild, moderate or severe...

RATIONALE: Calcific aortic stenosis (AS) is characterized by calcium deposition in valve leaflets. However, women present lower aortic valve calcification (AVC) loads than men for the same AS hemodynamic severity. OBJECTIVE: We thus aimed to assess sex-differences in aortic valve fibro-calcific remodelling. METHODS AND RESULTS: One hundred and twenty-five patients underwent Doppler-echocardiography and multidetector-computed-tomography within 3 months prior to aortic valve replacement...

BACKGROUND: Surgical timing of chronic aortic regurgitation (AR) remains a matter of debate because of limited data. This study assessed the prognostic value of exercise echocardiography in asymptomatic AR. METHODS: This prospective study included 60 consecutive asymptomatic patients with isolated moderate or severe AR (mean regurgitant volume 56.7 ± 11.8 ml) and preserved ejection fraction who underwent exercise echocardiography. The clinical outcomes were defined by the presence of major adverse cardiovascular events (MACE) and the indication for aortic valve replacement (AVR) with class I or IIa classification in the current guidelines...

Aortic stenosis is one the most frequent valvular diseases in developed countries, and its impact on public healthcare resources and assistance is increasing. A substantial proportion of elderly patients with severe aortic stenosis is frequently not eligible for surgery because of advanced age, frailty and multiple comorbidities. Transcatheter aortic valve implantation (TAVI) enables the treatment of very elderly patients at high or prohibitive surgical risk considered ineligible for surgery and with an acceptable life expectancy...

Primary mitral regurgitation (MR) owing to degenerative changes in the structural components of the mitral valve is a common acquired valvular pathology in the elderly. Surgical correction with mitral valve repair (MVRe) or replacement (MVR) is the mainstay of therapy. A significant proportion of patients are ineligible for MVRe/MVR owing to prohibitive surgical risk from advanced age, poor ventricular function, or associated comorbidities. Percutaneous mitral valve repair techniques have been developed to fill this void...
