Abstract:
Between 1979 and 1990, 190 patients underwent isolated aortic valve replacement at Seoul National University Hospital in Korea. There were 11 (5.8%) in-hospital deaths. Univariate analysis identified advanced age (p = 0.026), preoperative serum GOT or GPT greater than 40IU/1 (p 〈 0.001, p = 0.003), NYHA Class III or IV (p = 0.029), preoperative mean pulmonary arterial pressure greater than 19 mmHg (p = 0.019), reoperation for aortic valve replacement (p = 0.035), second or third open heart surgery (p 〈 0.001), and use of mechanical valve (p = 0.008) as variables associated with increased in-hospital risk. Follow-up documented survival rates of 98.1% and 96.4% and event-free survival rates of 95.7% and 81.6% at 3 and 7 postoperative years, respectively. NYHA Class III or IV (p = 0.009), preoperative serum total bilirubin level greater than 1.2 mg/dl (p = 0.009), reoperation for aortic valve replacement (p = 0.03), second or third open heart surgery (p = 0.002), and use of mechanical valve were associated with decreased late survival and event-free survival.
