Dynamic left ventricular outflow tract obstruction (DLVOTO) is a common condition in cats and humans. In this case report, a dog is described with DLVOTO secondary to severe intra-abdominal hemorrhage caused by a hemangiosarcoma. The dog was a 9-year-old, 35.7-kg, spayed female German Shepard dog that presented with a history of tachypnea and collapse. A Levine II/VI systolic murmur was present at the heart base. Abdominal ultrasonography revealed a splenic mass and a large amount of ascites. Echocardiography showed a reduced left ventricular diameter and an increased aortic velocity caused by systolic anterior motion (SAM) of the mitral valve apparatus. The heart murmur and the SAM were resolved after treatment including a splenectomy and a blood transfusion.
动态左心室流出道梗阻（DLVOTO）在猫和人类中是一种常见病症。在本病例报告中，描述了一只因血管肉瘤导致严重腹腔内出血继发DLVOTO的犬。这只犬为9岁、体重35.7千克的绝育雌性德国牧羊犬，有呼吸急促和虚脱病史。在心底部可闻及莱文氏II/VI级收缩期杂音。腹部超声检查发现脾脏肿块和大量腹水。超声心动图显示左心室直径减小，二尖瓣装置收缩期前向运动（SAM）导致主动脉流速增加。经过包括脾切除术和输血在内的治疗后，心脏杂音和SAM消失。
