OBJECTIVES The aim of this study was to examine 1-year outcomes of transseptal balloon-expandable transcatheter heart valve implantation in failed mitral bioprosthesis, ring annuloplasty, and mitral annular calcification (MAC). BACKGROUND Immediate outcomes following transseptal mitral valve implantation in failed bioprostheses are favorable, but data on subsequent outcomes are lacking. MET...
OBJECTIVES This study was undertaken to investigate time trends in early mortality, morbidity and clinical characteristics of patients undergoing heart valve surgery over the last decade. METHODS A regional, prospectively collected, study comprising all patients (2,327) undergoing valve surgery in a defined geographical area from January 1990 to December 1999 was conducted. Data were collecte...
Background Many high-risk patients with severe aortic stenosis cannot undergo valve replacement surgery due to calcification of the ascending aorta. Aortic valve bypass (AVB) surgery uses a conduit and prosthetic valve placed transapically into the left ventricle to divert flow from the apex of the heart through the conduit and prosthetic valve to the descending thoracic aorta to improve cardia...
In this review, in regard to the treatment of congenital heart disease, coronary artery diseases, valve disease and atrial fibrillation, novel surgeries and therapeutics are introduced according to our experience and recent report. In addition, robotics has gained acceptance in cardiac surgery, which is utilized to perform mitral valve repairs, coronary revascularization, atrial fibrillation ab...
background: conventional doppler measurements, including mitral inflow and pulmonary venous flow, are used to estimate left ventricular end diastolic pressure (lvedp). however, these parameters have limitations in predicting lvedp among patients with mitral regurgitation. this study sought to establish whether the correlation between measurements derived from tissue doppler echocardiography and...
Introduction: Rheumatic heart disease still remains one of the leading causes of congestive heart failure and death owing to valvular pathologies, in developing countries. Valve replacement still remains the treatment of choice in such patients.The aim of this study wasto analyze the postoperative outcome of double valve replacement (Mitral and Aortic ) in patients of rheumatic heart disease. ...
