A 7-year-old castrated male Munchkin cat was presented with anorexia. This cat had been diagnosed with chronic kidney disease due to polycystic kidney disease. Tachycardia with a systolic murmur (grade III/VI) was auscultated and for further diagnosis, echocardiography was performed. Based on echocardiography, persistent left cranial vena cava (PLCVC) was suspected due to enlargement of the coronary sinus and confirmed by saline contrast echocardiography. The dilated coronary sinus compressed the left atrium, and left ventricular hypertrophy with the systolic anterior motion of the mitral valve, aortic regurgitation, and mitral regurgitation were identified. After medical management using atenolol, left atrial function and other hemodynamics of the heart were improved, including the disappearance of regurgitation and normalization of left ventricular wall thickness. This case report describes the echocardiographic characteristics, diagnostic procedures, and disease progression in a cat with PLCVC after medical management using atenolol. Additionally, this is the first report of a cat with PLCVC, coexisting with polycystic kidney disease.
一只7岁去势雄性曼赤肯猫出现厌食症状。这只猫因多囊肾病被诊断为慢性肾病。听诊发现心动过速并伴有收缩期杂音（III/VI级），为进一步诊断，进行了超声心动图检查。基于超声心动图，由于冠状窦扩大怀疑存在永存左前腔静脉（PLCVC），并通过生理盐水对比超声心动图得以证实。扩张的冠状窦压迫左心房，发现左心室肥厚伴二尖瓣收缩期前向运动、主动脉瓣反流和二尖瓣反流。使用阿替洛尔进行药物治疗后，左心房功能和心脏的其他血流动力学指标得到改善，包括反流消失和左心室壁厚度恢复正常。本病例报告描述了使用阿替洛尔进行药物治疗后患有PLCVC的猫的超声心动图特征、诊断过程和疾病进展。此外，这是首例患有PLCVC且合并多囊肾病的猫的报告。
