Aortic valve replacement for aortic stenosis - 12 Year experience of a single surgeon

ABSTRACT

Aortic Valve Replacement [AVR] is a standard procedure carried out for severe pathological changes in aortic valve. In our study 30 patients had AVR for aortic stenosis from Dec. 1989 to Dec. 2002. There were 25 male and 5 female. Most of the patients were from poor socioeconomic group. Rheumatic heart disease was the most common cause [72.2%]. Syncope, angina and heart failure were the major indications of surgery. The mean age was 37 years. Starr Edward Valve was most commonly used valve [72.4%]. LV diastolic diameter was associated with increased pre-op NYHA grading, increased inotropic support. Hospital mortality was 5 [16.6%] and late death was 1[3.3%],4 [13.2%] patients were lost to follow up while 20[66.6%] are attending the follow up clinic with most of the cases in NYHA grade 0/I. Bleeding, infarction and postoperative arrhythmias affected the mortality significantly
