A typical case of advanced obstructive cardiomyopathy in a young subject was revealed by Streptococcal mitral valve endocarditis and was diagnosed by one and two dimensional echocardiography, which revealed a pedunculated vegetation on the large mitral valve and rupture of the chordae of the small mitral valve. This was complicated by biventricular heart failure, peripheral arterial embolism in the leg due to migration of the vegetation which disappeared on the repeat echocardiography and pulmonary embolism with arterial clot emboli due to heparin-induced thrombocytopenia. This condition resolved without requiring cardiac surgery. Patients with obstructive cardiomyopathy should be treated routinely with prophylactic antibiotics, particularly when dental treatment is required. Echocardiography has become an essential examination in the diagnosis of this disease and its complications, especially in cases with infectious endocarditis.
一名年轻患者的典型晚期梗阻性心肌病病例由链球菌性二尖瓣心内膜炎引发，通过一维及二维超声心动图得以诊断，该检查显示大二尖瓣上有一个带蒂赘生物，小二尖瓣腱索断裂。此病例并发双心室心力衰竭，赘生物脱落导致腿部外周动脉栓塞（在重复超声心动图检查时消失）以及肝素诱导的血小板减少症引发的动脉血栓栓塞性肺栓塞。该病情未经心脏手术即得到缓解。梗阻性心肌病患者应常规接受预防性抗生素治疗，尤其是在需要进行牙科治疗时。超声心动图已成为诊断此病及其并发症的重要检查手段，特别是在感染性心内膜炎病例中。
