Two cases of patients with discrete subaortic stenosis complicated by aortic regurgitation resulting from the sequelae of bacterial endocarditis and treated by valvular replacement are described. A correct preoperative evaluation was due to echocardiographic data and pressure curves; left ventriculography did not show any evidence of subaortic obstruction in any of the cases. In one patient, bacterial endocarditis involved mitral valve too, which was replaced by an artificial prostheses. Bacterial endocarditis is very rare in patients with discrete subaortic stenosis, but it must be regarded as a factor complicating the natural history of cardiopathy.
本文描述了两例因细菌性心内膜炎后遗症导致离散性主动脉瓣下狭窄合并主动脉瓣反流并接受瓣膜置换治疗的患者。术前通过超声心动图数据和压力曲线进行了正确评估；左心室造影在任何一例中均未显示主动脉瓣下梗阻的证据。在一名患者中，细菌性心内膜炎还累及二尖瓣，该瓣膜被人工假体置换。细菌性心内膜炎在离散性主动脉瓣下狭窄患者中非常罕见，但必须将其视为使心脏病自然病程复杂化的一个因素。
