OBJECTIVE: The aim of this study was to describe previously unrecognised or under-recognised adverse events associated with Melody® valve implantation. BACKGROUND: In rare diseases and conditions, it is typically not feasible to conduct large-scale safety trials before drug or device approval. Therefore, post-market surveillance mechanisms are necessary to detect rare but potentially serious adverse events. METHODS: We reviewed the United States Food and Drug Administration's Manufacturer and User Facility Device Experience (MAUDE) database and conducted a structured literature review to evaluate adverse events associated with on- and off-label Melody® valve implantation...

Oral anticoagulation plays an essential role in the treatment of patients with atrial fibrillation as it is indicated for most patients to reduce the risk of stroke. It is prudent to assess the risks of stroke and bleeding using the CHA2DS2-VASc and HAS-BLED scores. Oral anticoagulation is indicated in general for all patients with valvular atrial fibrillation (atrial fibrillation in moderate to severe mitral stenosis or mechanical prosthetic valve) as well as for patients with a CHA2DS2-VASc-Score of 1 - 2 points or higher...

Bile duct injuries (BDI) tend to be more complex in laparoscopic than in open cholecystectomy procedures, and frequently involve young adults with benign pathologies. The ultimate consequence may be a liver transplantation (LT), making this situation one of the most rare transplant indications. Fatal post-transplant outcome is extreme infrequently reported. Aim of this study is to report on our single-case experience and to review the literature concerning lethal outcome after LT for major BDI following cholecystectomy...

BACKGROUND: Gram-negative microorganisms are uncommon pathogens responsible for infective endocarditis. Pseudomonas mendocina, a Gram-negative water-borne and soil-borne bacterium, was first reported to cause human infection in 1992. Since then, it has rarely been reported as a human pathogen in the literature. We describe the first case of native valve infective endocarditis due to P. mendocina in the USA. CASE PRESENTATION: A 57-year-old white man presented with bilateral large leg ulcers, fever, and marked leukocytosis...

BACKGROUND: Dilatation of the ascending aorta tends to develop in individuals with aortic valve disease. Reduction ascending aortoplasty (RAA) is an alternative procedure to ascending aortic replacement. This study was designed to identify the early prognosis of RAA for patients with aortic valve disease and dilatation of the ascending aorta. METHODS: From January 2010 to December 2013, 102 patients with aortic valve disease and ascending aortic dilatation who had undergone aortic valve replacement combined with RAA were enrolled...

Systolic anterior motion of the mitral valve (SAM) occurs intraoperatively after mitral valve repair (MVRr) in up to 14% of cases and typically resolves in the operating room with conservative measures. Less commonly SAM may also occur in the early or late postoperative period. The clinical course and optimal management of such cases is poorly defined, but reoperation is common. We describe our experience using disopyramide to successfully treat postoperative SAM refractory to beta blockade. Seven patients were retrospectively identified with mitral valve prolapse who underwent MVRr from 2003 to 2015 and were found during follow-up to have severe SAM with a left ventricular outflow tract (LVOT) gradient not observed intraoperatively...

Congenital defects involving anomalous chordae of the mitral valve with attachment in the left atrium are an extremely rare finding and may result in valvular insufficiency. Few cases have been reported in the literature with multiple variations in anatomical location and insertion of aberrant chordae within the left ventricle and left atrium. Reported cases have presented with cardiovascular symptoms leading to diagnosis of anomalous mitral valve chordae. We present a case of a young female in which an aberrant mitral valve chorda was an incidental finding on transesophageal echocardiography...

Functional mitral regurgitation is a form of valve insufficiency in the presence of anatomically normal mitral valve. The cause of functional mitral regurgitation is left ventricular remodelling that tethers valve leaflet more apically decreasing their coaptation ability. Given the pathophysiologic relation between functional mitral regurgitation and ventricular dysfunction, the valve insufficiency has long been considered a surrogate of ventricular disease. Accordingly, all potential therapeutic strategies able to decrease functional mitral regurgitation have been associated with improved ventricular function...

OBJECTIVE: Transmitral blood flow produces a vortex ring (quantified using vortex formation time [VFT]) that enhances the efficiency of left ventricular (LV) filling. VFT is attenuated in LV hypertrophy resulting from aortic valve stenosis (AS) versus normal LV geometry. Many patients with AS also have aortic insufficiency (AI). The authors tested the hypothesis that moderate AI falsely elevates VFT by partially inhibiting mitral leaflet opening in patients with AS. DESIGN: Observational study...

A 76-year-old man was admitted to a community hospital due to a persistent high fever. He became afebrile after the administration of broad-spectrum antibiotics, but developed heart failure due to progressive aortic and mitral valve insufficiency and was transferred to our hospital. Although sequential blood cultures were negative, a broad-range polymerase chain reaction targeting the bacterial 16S-rRNA gene followed by the direct sequencing of whole blood revealed spa(+), mecA(-) and Panton-Valentine leukocidin (PVL)(+)...

BACKGROUND: Percutaneous mitral valve repair using MitraClip® (MC) is a well-established method for a subset of patients with severe mitral regurgitation (MR) and high risk for surgical intervention. Amplatzer® Cardiac Plug (ACP) occludes left atrial appendage and allows the discontinuation of oral anticoagulation and prevention of thromboembolic stroke. Due to the need for femoral and transseptal access in both procedures, a single approach could lead to minor risk of further complications and shorter cumulative intervention time...

The mitral valve (MV) is a highly complex cardiac valve consisting of an annulus, anterior and posterior leaflets, chordae tendineae (chords) and two papillary muscles. The chordae tendineae mechanics play a pivotal role in proper MV function: the chords help maintain proper leaflet coaptation and rupture of the chordae tendineae due to disease or aging can lead to mitral valve insufficiency. Therefore, the aim of this study was to characterize the mechanical properties of aged human and ovine mitral chordae tendineae...
