Echophonographic findings of three patients with spontaneous degeneration of porcine tricuspid and mitral valves presenting with musical murmurs are reported. Echocardiography in all these patients revealed systolic or diastolic cusp flutter similar in frequency to the musical murmur on simultaneously recorded phonocardiogram. Porcine tricuspid regurgitation is usually well tolerated and can be followed clinically for many years. However, patients with mitral porcine valves usually become symptomatic or present with congestive heart failure and usually require valve surgery soon after clinical or echo-phonocardiographic findings of valve regurgitation appear.
报告了三例猪三尖瓣和二尖瓣自发性退变伴音乐性杂音患者的超声心动图检查结果。所有这些患者的超声心动图均显示收缩期或舒张期瓣叶扑动，其频率与同时记录的心音图上的音乐性杂音相似。猪三尖瓣反流通常耐受性良好，可临床随访多年。然而，猪二尖瓣患者通常会出现症状或出现充血性心力衰竭，通常在临床或超声心动图检查发现瓣膜反流后不久就需要进行瓣膜手术。
