BACKGROUND The United Kingdom Heart Valve Registry (UKHVR) has recently completed collecting information on 52 659 heart valve replacements (in 47 718 patients) performed during the period 1986 to 1995 in the whole of the United Kingdom. Information stored in the UKHVR's computer database was used for this study. Factors affecting the time from first prosthesis to first redo prosthesis were ana...

conclusions systemic arterial leukocyte filtration reduces the intubation time but has no other beneficial effect on the outcome of patients undergoing cabg or valve surgery. results the postoperative intubation time was significantly shorter in patients with leukocyte filters (0.014). there was no significant difference between two groups regarding other outcome relatedvariables. patients and ...

Relevant secondary mitral regurgitation occurs in 35– 50% of patients with chronic heart failure and is associated with increased mortality. Surgical management of patients with mitral valve regurgitation and heart failure remains controversial. There are several questions which are not sufficiently clarified because of a lack of prospective randomised controlled trials: (1.) The indication for...

a total of 14 cases of infective endocarditis (ie) in children aged 6 months to 10 years were seen from december 1987 to december 1992 at the pediatric unit of ayatollah taleghani medical center. the majority of patients (12 of 14) were between 5 and 10 years of age. acyanotic congenital heart disease was known to preexist in 78.6% and rheumatic valvular heart disease in 21.4% of cases. organis...

Organic disease of the tricuspid valve required surgery in 18% of all patients undergoing valve replacement over a five-year period. Differentiation of organic from functional disease is difficult and may be made only at open-heart surgery. The results of a series of 56 patients who underwent tricuspid valve replacement are presented; of these, 53 had organic disease. Operative mortality at the...

BACKGROUND The long-term benefits of the maze procedure in patients with chronic atrial fibrillation undergoing mechanical valve replacement who already require lifelong anticoagulation remain unclear. METHODS AND RESULTS We evaluated adverse outcomes (death; thromboembolic events; composite of death, heart failure, or valve-related complications) in 569 patients with atrial fibrillation-asso...

introduction:  in patients who underwent surgery to repair tetralogy of fallot, right ventricular dilation from pulmonary regurgitation may be result in right ventricular failure, arrhythmias and cardiac arrest. hence, pulmonary valve replacement may be necessary to reduce right ventricular volume overload. the aim of present study was to assess the effects of pulmonary valve replacement on rig...

in recent socio-economic state it is not possible to have different sets of prosthetic cardiac valves available in the operating room before open-heart surgery for valvular replacement. in this study the diameter of the aortic valve ring measured in 2-d echocardiography was compared with the size of the aortic prosthetic valves implanted for the patients with aortic valvular disease. the purpos...
