OBJECTIVES Whether to repair or replace the mitral valve for patients with significant mitral regurgitation undergoing aortic valve replacement is still controversial. METHODS From January 1990 to December 2011, a total of 663 patients underwent aortic valve replacement combined with mitral valve surgery. Among these, 253 patients (mean age 55.9 ± 14.5 years, 91 females) with moderate-to-seve...

BACKGROUND In patients with bicuspid aortic valve and dilated proximal ascending aorta, we sought to assess (1) factors associated with increased longer-term cardiovascular mortality and (2) incremental prognostic use of indexing aortic root to patient height. METHODS AND RESULTS We studied 969 consecutive bicuspid aortic valve patients (50±13 years; 87% men) with proximal aorta ≥4 cm, who al...

Background: Beta-thalassemia major is a severe and lethal hemolytic anemia. Regular transfusion is necessary for avoidance of its complications but it may end to cardiac involvement secondary to iron overload. Angiotensin converting enzyme inhibitors (ACEIs) are useful medications even in early stages of heart failure. We studied the effects of two common ACEIs on improvement of heart function ...

Patients with metallic prosthetic heart valves have to use anticoagulants throughout their life because of avoiding prosthetic valve thrombosis. We report the case of a patient with a prosthetic aortic valve without any event to date despite not using warfarin for 31 years. A 53-year-old man who underwent aortic valve replacement (AVR) with a mechanical valve (Medtronic,Inc., Minneapolis, Mines...

A 43-year—old man was admitted to the coronary care unit because of recurrent syncope. His medical history included pulmonic valve angioplasty at age 9 years, mechanical mitral valve replacement because of severe mitral regur-gitation caused by congenital atrioventricular canal, and pacemaker implantation because of complete atrioventricular block. On admission he was orthopneic, his blood pres...
