Abstract
In a 12-yr period, 127 patients with isolated aortic valve disease underwent valve replacement surgery. Long-term results are presented in regard to patients with operation between 1967 and 1974 and immediate results in the later cases. The type of myocardial protection evidently is important for the perioperative mortality rate. This rate was 18% in patients operated on in normothermia and 6% in those with chemical cardioplegia. No significant correlation was found between preoperative NYHA [New York Hospital Association] grouping and mortality or complication rate, and the long-term result was independent of the type of valvular prosthesis.
