RATIONALE: Drug-induced valvular heart disease (DI-VHD) remains an under-recognized entity. PATIENT CONCERNS: This report describes a heart valve replacement which was complicated by intractable systemic pulmonary arterial hypertension in a 61-year-old female with severe restrictive mitral and aortic disease. The diagnosis of valvular disease was preceded by a history of unexplained respiratory distress. The patient had been exposed to benfluorex for 6.5 years. DIAGNOSES: The diagnostic procedure documented specific drug-induced valvular fibrosis...

We report the case of early recurrence of Tako-Tsubo cardiomyopathy in an elderly woman with amyotrophic lateral sclerosis triggered by different stressors. A first episode with typical apical ballooning was anticipated by an emotional stress; a second, characterized by systolic anterior motion of the mitral valve associated with mitral regurgitation and severe intra-ventricular gradient, was precipitated by surgical stress and hypovolemia. We therefore hypothesize both a possible link between amyotrophic lateral sclerosis and Tako-Tsubo cardiomyopathy, and between different stressors and different Tako-Tsubo patterns...

OBJECTIVES: Reoperative procedure for the treatment of a failed mitral bioprosthesis is associated with considerable risk. In some cases, mortality is high and might contraindicate the benefit of the procedure. The minimally invasive valve-in-valve (ViV) transcatheter mitral valve implant offers an alternative less-invasive approach, reducing morbidity and mortality. The objective of this paper was to evaluate the mitral ViV approach using the Braile Inovare prosthesis. METHODS: The transcatheter balloon-expandable Braile Inovare prosthesis was used in 12 cases...

AIMS: Quantitative mitral regurgitation (MR) grading remains challenging. This study evaluated the concept of integrating echocardiography and computed tomography for grading MR severity. Specifically, an integrated parameter was developed that combines the true cross-sectional mitral regurgitant orifice area (ROA) assessed with multi-detector row computed tomography (MDCT) with flow data from echocardiography. METHODS AND RESULTS: Systolic MDCT data of 73 patients, referred for transcatheter aortic valve implantation (TAVI) who also had MR, were evaluated...

Acromelic dysplasias are a group of skeletal dysplasias characterised by short-limbed short stature with other distinctive phenotypic features including small hands and feet and stiff joints. Geleophysic dysplasia is an acromelic dysplasia that is associated with characteristic facial features, progressive cardiac valvular thickening, and tracheal stenosis. Owing to overlapping clinical features with other types of short-limbed skeletal dysplasias, it is important to make a precise diagnosis as they have different cardiac morbidity and mortality...

Background There are limited data regarding the risks of cardiac surgery early after coronary angiography in patients scheduled for isolated aortic and/or mitral valve replacement. Our aim was to evaluate the risk of early surgery after coronary angiography in these patients. Methods We retrospectively analyzed data of 1044 patients who underwent isolated aortic and/or mitral valve replacement from 2006 to 2014. Baseline, operative, and postoperative variables were collected. The patients were divided into 3 groups based on the interval between coronary angiography and surgery: ≤3 days ( n = 216), 4-7 days ( n = 109), and ≥8 days ( n = 719)...

AIMS: Permanent pacemaker placement (PPM) is often required after valvular surgery and is especially common following tricuspid valve surgery [tricuspid valve repair or replacement (TVR)]. Literature suggests that surgical intervention for isolated tricuspid valve disease is becoming more prevalent. Predictors of PPM dependency following TVR are currently unknown and would be clinically useful from a prognostication standpoint. METHODS AND RESULTS: We conducted a multicentre, retrospective study to assess perioperative factors of TVR that predispose to PPM placement and long-term PPM dependency from 2008 to 2014...

The current trend to treat hypotension in critically ill patients is to place a greater emphasis on inotropic support and less on fluid resuscitation in order to limit the potential harm from fluid overload. This combination may trigger left ventricular outflow tract obstruction (LVOTO) in susceptible patients. Although LVOTO is classically described in patients with hypertrophic cardiomyopathy it has been reported in other conditions including septic shock, apical ballooning syndrome, myocardial infarction, respiratory failure, and post valvular surgery...

Background Chronic Rheumatic Heart disease (RHD) continues to be a health problem in many low and middle income countries and especially in sub-Saharan Africa. Echocardiography has shown that the disease is far more widespread than may be detected by clinical assessment, but data are lacking on the prevalence and epidemiological features in rural Africa. Design Community-based prevalence survey Methods We used transthoracic echocardiography to carry out a population-based study of RHD in a rural area of Ethiopia...

INTRODUCTION: The mitral valve area (MVA) poorly reflects the hemodynamic status of (MS). In this study, we compared the MVA with mitral valve resistance (MVR) with regard to the determination of hemodynamic consequences of MS and the immediate outcomes of percutaneous balloon mitral valvuloplasty (PBMV). METHODS: In a prospective study, 36 patients with severe rheumatic MS with left ventricular ejection fraction (LVEF) >50% were evaluated. They underwent transthoracic echocardiography (TTE) and catheterization...

Functional mitral regurgitation (FMR) is a significant complication of left ventricular dysfunction and strongly associated with a poor prognosis. In this study, we developed a patient-specific finite element (FE) model of the mitral apparatus in a FMR patient which included: both leaflets with thickness, annulus, chordae tendineae, and chordae insertions on the leaflets and origins on the papillary muscles. The FE model incorporated human age- and gender-matched anisotropic hyperelastic material properties, and MV closure at systole was simulated...

AIMS: Myxomatous valve disease (MVD) is the most common aetiology of primary mitral regurgitation. Recent studies suggest that defects in heart valve development can lead to heart valve disease in adults. Wnt/β-catenin signalling is active during heart valve development and has been reported in human MVD. The consequences of increased Wnt/β-catenin signalling due to Axin2 deficiency in postnatal valve remodelling and pathogenesis of MVD were determined. METHODS AND RESULTS: To investigate the role of Wnt/β-catenin signalling, we analysed heart valves from mice deficient in Axin2 (KO), a negative regulator of Wnt/β-catenin signalling...

BACKGROUND: Percutaneous edge-to-edge mitral valve repair (PMVR) recently emerged as an effective treatment modality for patients with severe mitral regurgitation (MR). Length of postprocedural hospital stay may represent a modifiable cost associated with percutaneous treatment. We looked at feasibility, predictors and safety of early discharge (ED), defined as hospital discharge within 72 hours, in patients undergoing PMVR. METHODS AND RESULTS: Consecutive patients treated with MitraClip from October 2008 to December 2015 were analysed...

BACKGROUND: The prevalence of ventricular dysrhythmias (VD) [ventricular premature beats (VPBs), ventricular couplets (Vcouplets), ventricular runs (Vruns)] after coronary artery bypass grafting (CABG) has so far not been examined. The goal of this study is to examine characteristics of VD and whether they precede ventricular tachyarrhythmias (VTA) during a postoperative follow-up period of 5 days using continuous rhythm registrations. In addition, we determined predictive factors of VD/VTA...

BACKGROUND: Annuloplasty bands and rings are widely used for repairing functional tricuspid regurgitation (FTR). However, the question regarding which is the ideal annuloplasty device remains unclear. The aim of this study was to compare the efficacy and mid-term durability of tricuspid ring annuloplasty for FTR secondary to rheumatic mitral valve disease using flexible Cosgrove-Edwards band and the rigid Edwards MC3 ring (Edwards Lifesciences, LLC, Irvine, CA, USA). METHODS: We retrospectively collected the clinical data of those who underwent mitral valve replacement (MVR) in concomitant with tricuspid ring annuloplasty from 2009 to 2013...
