Comparative analysis of prosthetic heart valve replacement on the basis of 300 cases

Comparative analysis of prosthetic heart valve replacement on the basis of 300 cases

Journal of Cardiovascular Surgery 16(5): 526-534

1. The 224 patients have been followed-up for postoperative intervals of 1 to 8 years after operation, and the average duration of the follow-up has been 4 years. 2. Six types of heart valve prostheses have been utilized and evaluated with the longest (9 years) period of follow-up (a Starr-Edwards prothesis) and the shortest a Björk-Shiley valve. The best clinical hemodynamic characteristics, no thromboembolic complications were observed with the Lillehei-Kaster valve. Evaluation of longterm wear and thrombosis require further follow-up studies. 3. All patients, but 21, improved in functional capacity and are NYHA class I and II. Most of the patients had heart failure at the time of operation. These patients would have had a life expectancy of about two years from the onset of symptoms. Seventy two patients with heart failure as a prime symptom have thus outlived their anticipated life expectancy. 4. Systemic embolization was the most common postoperative complication in spite of the anticoagulant therapy.
