Aortic valve stenosis is the most common valve disease in the western world. Over the past few years the number of aortic valve replacement (AVR) interventions has increased with outcomes that have been improved despite increasing age of patients and increasing burden of comorbidities. However, despite such excellent results and its well-established position, conventional AVR has undergone grea...

Increased destruction of red blood cells follows the insertion of ball valves into the heart in most cases. Usually, hemolysis is slight, but in some patients uncompensated hemolytic anemia develops. To study the influence on hemolysis of the mechanical properties of the prostheses, the degree of erythrocyte destruction was evaluated in patients with Starr-Edwards aortic prostheses of different...

Since 1955, with the progress of safer methods of extra corporeal circularion, open heart surgery started to go through great advancements. As far as the treatment of vaive disease is concerned those improvements made it possible to think about repla cing the diseased heart valves with prostheses. Even before the era of open heart surgery, correction of aortic insufficiency had been clinically ...

OBJECTIVE We analyzed the long-term morbidity and mortality of our experience with combined mitral-aortic surgery, as well as their determinants. METHODS Among 2109 consecutive patients undergoing valve operations, 200 had mitral-aortic valve procedures with at least implantation of a mechanical prosthesis: 163 of 200 (81.5%) patients had double valve replacement and 37 of 200 (18.5%) had mit...

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. ...

OBJECTIVE To assess the 30-day mortality, long-term survival and freedom from reoperation following surgery for prosthetic endocarditis (PVE). METHOD A retrospective analysis of data from the UK Heart Valve Registry of 322 patients who had undergone single mechanical/bioprosthetic valve replacement for PVE between 1 January 1986 and 31 December 1996. The mean age was 54.9 +/- 12.8 years and 2...
