Endocardial splitting and left atrial rupture were diagnosed in a dog with mitral regurgitation that experienced the sudden onset of collapsing episodes, weakness, depression, labored breathing, and weak pulses. Thoracic radiographs showed a rounded cardiac silhouette with prominent left atrium consistent with hemopericardium due to left atrial rupture. Two-dimensional echocardiography confirmed the presence of severe mitral valve disease, pericardial fluid, and a laminated blood clot caudal to the left ventricle. A sterile emergency thoracotomy was performed, the hemopericardium and blood clot were removed, and the rupture site in the left atrium was repaired with reinforced sutures. The dog recovered from surgery but died the next day, presumably from a ventricular arrhythmia.
在一只患有二尖瓣反流的犬中诊断出心内膜破裂和左心房破裂，该犬突然出现虚脱发作、虚弱、抑郁、呼吸费力和脉搏微弱。胸部X线片显示心脏轮廓呈圆形，左心房突出，符合左心房破裂导致的心包积血。二维超声心动图证实存在严重的二尖瓣疾病、心包积液以及左心室后方的分层血凝块。进行了无菌紧急开胸手术，清除了心包积血和血凝块，并用加强缝线修复了左心房的破裂部位。这只犬术后恢复，但第二天死亡，推测是死于室性心律失常。
