The first case of overt hemolytic anemia following mitral valve replacement with a porcine heterograft is reported. Cardiac catheterization failed to reveal a paravalvular leak or valvular incompetence to account for the hemolysis. Red cell traumatization by the Dacron-covered Stellite ring and stent is suggested as the cause of hemolysis with the porcine heterograft.
报道了首例二尖瓣置换猪异种移植物后出现明显溶血性贫血的病例。心导管检查未能发现瓣周漏或瓣膜功能不全以解释溶血情况。推测涤纶覆盖的钴铬合金环和支架对红细胞的损伤是猪异种移植物导致溶血的原因。
