transcatheter aortic valve replacement (tavr) is a novel therapeutic intervention for the replacement of severely stenotic aortic valves in high-risk patients for standard surgical procedures. since the initial partner trial results, use of tavr has been on the rise each year. new delivery methods and different valves have been developed and modified in order to promote the minimally invasive p...

from may 1994 to december 1996 thirty patients received viable fresh aortic homografts. mean age was 55 years (13 to 70), male to female ratio was 2/1, 24 operations were elective whereas 6 were semiurgent. predominant lesions were aortic stenosis or regurgitation in lb patients, aortic valve endocarditis in 10, prosthetic valve dysfunction in 3, and aortic root pathology in one patient. from t...

a 46 year old man had been undergone aortic valve replacement (avr) due to mechanical aortic valve endocarditis two month ago. he was referred to imam khomeini hospital because of dyspnea since two weeks ago. echocardiography showed the false aneurysm, with an area of flow beyond the lumen of the aorta. this patient underwent reoperation, the previously implanted aortic valve was removed, metic...

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...

splenomegaly-induced thrombocytopenia is fully described in hematological and surgical literature, but its association with severe aortic stenosis is rare. we present a case of severe aortic valve stenosis with severe splenomegaly-induced thrombocytopenia in which aortic valve replacement was done with a number 23 homograft and splenectomy was performed after the end of cardiopulmonary bypass. ...

conclusions high risk patients needing avr are optimal candidates for transcatheter aortic valve implantation. tavi is a valuable solution for high risk patients needing avr. obtained results are comparable to results in transthoracic avr in standard candidates for aortic valve implantation. background transcatheter aortic valve implantation (tavi) has emerged as an alternative treatment to cla...

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. ...
