BACKGROUND Long-term outcome of patients treated with a St. Jude prosthetic heart valve was reported by investigators in Lausanne, Switzerland. This article quantifies the mortality and morbidity implications of single or multiple heart valve replacement. RESULTS After hospital discharge, mortality ratios were highest for duration 5-10 years, roughly comparable in patients who received a sing...

transcatheteraortic valve implantation, first introduced in 2002, has been established as an alternative modality for patients deemed not suitable for open-heart surgery. the anatomical vicinity of the atrioventricular node and the his bundle to the non-coronary and rightcoronary aortic cusps predisposes patients to conduction abnormalities in case of severe calcification or mechanical trauma d...

This report deals with a rare complication of disc-valve prosthesis in the mitral area. A significant disc poppet and struts destruction of mitral BeaU valve prostheses occurred 20 and 17 months after implantation. The resulting valve incompetence in the first case contributed to the death of the patient. The durability of Teflon prosthetic valves appears to be in question and this type of valv...

Thrombosis of mechanical heart valve prosthesis is a rare fatal complication after heart valve replacement. This report describes an old female patient with aortic prosthetic valve thrombosis who had a successful fibrinolytic treatment.

BACKGROUND The purpose of this study is to examine the influence of the prosthesis type on early mortality and long-term survival after re-replacement of aortic valve prosthesis, especially in patients over 60 years old. METHODS Late outcome of 223 patients who underwent a reoperation on the aortic valve and received a mechanical (mechanical group) or biological (biological group) heart valve...

INTRODUCTION Patients with mechanical heart valve prostheses must continuously be treated with oral anticoagulants to prevent thromboembolic events related to prosthetesis. These patients should be continually evaluated for the control of oral anticoagulation. OBJECTIVE To compare the occurrence of thromboembolic and hemorragic complications in patients with mechanical heart valve prosthesis ...

Objective(s): Tissue engineering represents a new approach to solve the current complications of the heart valve replacements by offering viable valve prosthesis with growth and remodeling capability. In this project, electrospinning and dip coating techniques were used to fabricate heart valve constructs from medical grade polyurethane (PU). Methods: Fir...

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...

surgery for heart diseases during pregnancy, especially necessitating cardiopulmonary bypass, is believed to trigger maternal and fetal risks and should be performed only when medical therapy has been unsuccessful to alleviate the cardiac decompensation. a 33-year-old pregnant woman in her 33rd week of gestation was admitted to our hospital. she had rheumatic mitral valvular stenosis and had un...
