Because of concerns about the hemodynamic performance of 19-mm porcine valves, we retrospectively reviewed the clinical results and echocardiographic studies of 52 consecutive patients who received a 19- mm Carpentier-Edwards porcine bioprosthesis (model 2625) for aortic valve replacement from 1986 through 1991. Nearly 87% of the patients were women, the mean age was 69 years, and the mean body surface area was 1.63 +/- 0.27 m2. Seventy-three percent of the patients had pure aortic stenosis, 96% were in New York Heart Association classes III and IV, and 56% underwent urgent or emergent operation. Overall hospital mortality was 7.7% with a late mortality of 8.3% at a mean follow-up of 25 +/- 18 months. No patient experienced a valve-related complication, and 95% of surviving patients were in New York Heart Association classes I and II. Two-dimensional and Doppler echocardiography performed during the first postoperative week revealed a maximal instantaneous gradient of 44.7 +/- 13.0 mm Hg. In 43 patients for whom additional data were available, the mean gradient was 26.4 +/- 8.2 mm Hg with an effective orifice area of 0.85 +/- 0.18 cm2. This study defines the normal range of postoperative gradients across the 19-mm Carpentier-Edwards porcine valve and demonstrates that patients receiving this valve can achieve significant clinical improvement despite the presence of high transvalvular gradients measured by echocardiography.
