We studied the haemodynamic effects of inhaled nitric oxide 40 p.p.m. in two groups of patients after cardiac surgery (mitral valve surgery or coronary artery bypass grafting). Nitric oxide caused a significant reduction in pulmonary vascular resistance after mitral valve surgery in patients who had pre-existing pulmonary hypertension, but no change in haemodynamic state in the coronary artery ...

A 75-year-old woman who had previously undergone a double valve replacement was admitted to Asan Medical Center because of severe bioprosthetic mitral valve dysfunction and tricuspid regurgitation. Under hypothermic fibrillatory arrest without aortic cross-clamping, minimally invasive mitral and tricuspid valve surgery was performed via a right minithoracotomy.

OBJECTIVE To determine the pattern of anticoagulation control for post heart-valve surgery for patients on follow up at Kenyatta National Hospital (KNH). DESIGN A combined prospective and restrospective hospital-based study. Retrospective period from January 1991 to 31st August 1997, while the prospective period was from 1st September 1997 to 31st November 1999. SETTING Cardiothoracic surge...

INTRODUCTION AND OBJECTIVES Mitral valve disease often is accompanied by chronic atrial fibrillation, especially when the left atrium is enlarged. Mitral valve surgery alone cannot resolve the arrhythmia in most cases. Several surgical techniques have been proposed. We have used surgical left atrial reduction and pulmonary vein isolation to eliminate chronic atrial fibrillation associated with ...

BACKGROUND Mitral regurgitation is one of the leading causes of cardiovascular morbidity in pediatric patients with Marfan syndrome. The purpose of this study was to contribute to determining the appropriate surgical strategy for these patients. METHODS From January 1992 to May 2013, six patients with Marfan syndrome underwent surgery for mitral regurgitation in infancy or early childhood. ...

The fastest growing demographic group in Europe and America is the elderly, and significant mitral regurgitation is very prevalent in this population. At present, with mitral valve surgery in elderly individuals gaining greater acceptance worldwide, the question whether to repair or replace the valve remains controversial. Recent studies have demonstrated the safety, feasibility, and durability...

Previously unreported echocardiographic findings are described of two cases with anterior mitral valve leaflet fenestration associated with infective endocarditis. M-mode echocardiograms demonstrated a periodic interruption in the echo tracing of the mitral valve ring area. Long axis real time two dimensional echocardiograms showed an echo defect in the body portion of the anterior mitral valve...

OPINION STATEMENT More attention has been paid to the mitral valve (MV) than the tricuspid valve (TV), and this relative paucity of data has led to confusion regarding the timing of TV surgery. We review the American College of Cardiology/American Heart Association and European Society of Cardiology guidelines to identify areas of concordance (severe tricuspid regurgitation [TR] in a patient un...
