Reduced intimal hyperplasia in rabbits via medical therapy after carotid venous bypass.

Intimal hyperplasia is a major cause of restenosis after the interventional or surgical treatment of occlusive arterial disease. We investigated the effects of clopidogrel, calcium dobesilate, nebivolol, and atorvastatin on the development of intimal hyperplasia in rabbits after carotid venous bypass surgery. We divided 40 male New Zealand rabbits into 4 study groups and 1 control group.

Detection of flail tricuspid valve many years after blunt chest trauma.

Posttraumatic tricuspid insufficiency is a rare clinical entity that is mostly associated with traffic accidents causing nonpenetrating chest wall injury. Here we report a patient with a flail tricuspid valve detected many years after blunt chest trauma at work place.

Risk factors for stroke following coronary artery bypass operations.

Background: Although the overall complication rates have been decreased significantly in recent years, stroke rates still remain high in patients undergoing coronary bypass operations. This study is designed to evaluate the risk factors for stroke in patients who had undergone coronary artery bypass surgery in an 8-year period in our clinic.

Methods: Between 1995 and 2003, 8547 coronary artery operations under cardiopulmonary bypass were performed.

Regression of left ventricular hypertrophy after aortic valve replacement in patients over 55 years old with different valve types.

Background: We planned a prospective study to evaluate the regression of left ventricular mass one year after surgery in older patients (
Material/methods: Between 1998 and 2000, 54 patients had aortic valve replacement with stentless bioprostheses (14 CryoLife-O'Brien, 40 Medtronic Freestyle), and 62 patients had aortic valve replacement with St. Jude Medical mechanical valve.

Coronary artery anomalies in adult patients.

Background: Coronary artery anomalies are discovered in less than 1% of angiography series. Since the number of angiographies and coronary bypass operations are increasing significantly every day, these anomalies are of clinical importance.

Material/methods: 58,023 coronary angiographies were performed in the cardiology clinic of our hospital from 1978 to 2001.
