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...

BACKGROUND Aortic valve replacement with cardiopulmonary bypass is currently the treatment of choice for symptomatic aortic stenosis but carries a significant risk of morbidity and mortality, particularly in patients with comorbidities. Recently, percutaneous transfemoral aortic valve implantation has been proposed as a viable alternative in selected patients. We describe our experience with a ...

OBJECTIVES This paper investigates the radial deformation load of an aortic endoluminal prosthesis and determines the longitudinal load required to cause migration in a human cadaveric aorta of the endoprosthesis. DESIGN AND METHODS The endovascular prosthesis under investigation was a 24 mm diameter, nitinol, self-expanding aortoaortic device (InterVascular, Clearwater, Florida, U.S.A.). Ini...

A 42-year-old woman was diagnosed by cardiac catheterization as having severe mitral stenosis and grade-3/4 aortic regurgitation. The patient underwent mitral commissurotomy and replacement of the aortic valve with a No. 21 Bj#{246}rkShiley tilting-disk prosthesis. The prosthesis was fixed in place with 16 single sutures (Ethiflex). In the immediate postoperative period the clinical picture and...

Giant ascending aortic aneurysm formation following aortic valve replacement is rare. A 28-year-old man who underwent aortic valve replacement with a prosthetic valve for aortic regurgitation secondary to congenital bicuspid aortic valve about 10 years ago was diagnosed with a giant ascending aortic aneurysm about 16 cm in diameter in follow-up. The aneurysm was resected leaving the functional ...

BACKGROUND Transcatheter aortic valve implantation is a highly specialized technique offering a new therapeutic option to patients at high risk for conventional surgery. Complications associated with this catheter procedure differ from complications after surgical aortic valve replacement. This is to report incidence, management, and impact on morbidity and mortality of CoreValve dislocation du...

Nineteen patients with morphological abnormalities of the red blood cells are described, and these formed approximately 3% of the total cases of cardiac valvular disease. In two patients the abnormal blood film developed after the insertion of an aortic and mitral valve prosthesis respectively, but in another two patients the abnormal blood film was corrected by aortic valve surgery. Anisopoiki...

SYNOPSIS Nineteen patients with morphological abnormalities of the red blood cells are described, and these formed approximately 3 % of the total cases of cardiac valvular disease. In two patients the abnormal blood film developed after the insertion of an aortic and mitral valve prosthesis respectively, but in another two patients the abnormal blood film was corrected by aortic valve surgery. ...

INTRODUCTION AND OBJECTIVES It is still not clear whether the presence of a moderate patient-prosthesis mismatch after isolated aortic valve replacement can increase 30-day mortality. The aim of this study was to determine whether a moderate mismatch is an independent predictor of early global or cardiac mortality after aortic valve replacement. METHODS The study involved 272 adult patients (...

BACKGROUND Transcatheter aortic valve implantation (TAVI) has proven to be a valid option for patients with severe aortic stenosis who are at high perioperative risk, particularly in patients with previous cardiac surgery. Several patients with previous mitral valve surgery were reported to have been successfully treated with TAVI. CASE PRESENTATION Two patients, one with mechanical and one w...
