“…valves and to the findings of Kawachi et al 25 Larger orifice areas were found in another study of the lonescu bioprosthesis (1.34 and 1.49 cm 2 for 19-and 21-mm size valves, re- spectively), but a meaningful comparison is not possible due to the lack of information regarding the technique used for hemodynamic measurements. 8 The Carpentier-Edwards bovine pericardia! bioprosthesis has been an excellent valve substitute for aortic valve replacement up to five years after operation.…”

From 1981 to 1987, 189 patients underwent isolated aortic valve replacement with the Carpentier‐Edwards bovine pericardial bioprosthesis. There were 9 early deaths (30‐day mortality of 4.8%) and 18 late deaths (3.3% pt‐yr). After 5 years, the actuarial survival rate was 81.9%. All patients but one were followed for an average of 37 months after operation, and follow‐up totaled 551 patient‐years. Valve‐related complications inciuded 12 thromboembolic episodes (2.2%/pt‐yr), 7 endocarditis (1.3%/pt‐yr), 2 hemorrhages due to anticoagulation (0.4%/pt‐yr), and 3 reoperations (0.5%/pt‐yr). After five years, freedom from thromboembolic events was 91%, that from reoperation was 98%, and 87% for all valve‐related complications. There was no primary tissue failure of the valve. Before operation, 55% of the patients were in functional Class III or IV, 97% of the survivors were in Class I or II after valve replacement. Hematological evalvation of 77 patients, an average of 18 months postoperatively, showed no clinically significant hemolysis. Postoperative hemodynamic studies in 28 patients showed mean aortic pressure gradients across the prosthesis at rest ranging from 24 mmHg with the smaller (19 mm) to 11 mmHg with the larger (25 mm and more) valves, and effective orifice areas ranging from 1.0 to 1.9 cm2, respectively. Thus, the Carpentier‐Edwards pericardial bioprosthesis appears to be a reliable and hemodynamically effective substitute for replacement of the aortic valve.

“…There were 26 hospital deaths (10.7%) due to low cardiac output (14), infection (6), dysrrhythmia (3), hemorrhage (1), neurological complications (1), and left ventricular rupture (1). Twenty-three of 241 had concomitant cardiac surgery, while the other 3 hospital deaths were isolated aortic valve replacements (3/241).…”

From August 1977 through October 1984, 241 patients underwent aortic valve replacement with the Ionescu‐Shiley pericardial valve. There were 130 males and 11 females in this series with an average age of 50.8 years (range 15 to 78 years). Isolated aortic valve replacement was performed in 121 patients (50.2%) and associated cardiac surgery in 120 (49.8%). Valve size was 21 mm or smaller in 107 cases (50.2%). Cumulative duration of follow‐up was 1,260 patient‐years with a mean follow‐up of 5.16 years per patient. Five patients were lost to follow‐up. Maximum follow‐up was 10.5 years. There were 26 hospital deaths and 15 late deaths (1.19% per pt‐yr). The expected 10.5 year actuarial survival rate is 82% ± 2.9%. Twelve thromboembolic episodes occurred in seven patients ‐ seven central and five peripheral events. The thromboembolic rate was 0.95% per patient‐year ‐ 32% for patients with isolated aortic valve replacement and 0.63% for patients with concomitant surgery. Freedom from thromboembolic episodes at 10.5 years is 73% ± 12%. Structural valve deterioration was found in 24 patients (1.9% per pt‐yr) with an actuarial freedom from primary tissue failure of 77.5% ± 5.4% at 10.5 years. Reoperation was required in 39 cases (3.09% per pt‐yr) ‐ primary tissue failure (n = 24), paravalvular leak (n = 7), infective endocarditis (n = 6), and valve thrombosis (n = 2).
