Abstract

BACKGROUND

The aorto-left ventricular tunnel (ALVT) is a congenital extracardiac channel that connects the ascending aorta to the left ventricle.

CASE DESCRIPTION

A 2-year-old Shih-tzu dog presented with mild exercise intolerance. Echocardiography revealed an abnormal slit-like tunnel structure connecting the ascending aorta to the left ventricle, with diastolic blood flow from the aorta to the left ventricle. Echogenic membranous stenosis was observed in the main pulmonary artery. Based on these findings, the dog was diagnosed with ALVT and type I supravalvular pulmonic stenosis.

CONCLUSION

This is the first case report of ALVT in veterinary medicine that describes diagnostic imaging findings. ALVT should be considered in dogs with an aortic regurgitation murmur and can be detected by echocardiography.

摘要

背景

主动脉-左心室隧道（ALVT）是一种先天性的心脏外通道，连接升主动脉和左心室。

病例描述

一只 2 岁的西施犬表现出轻度运动不耐受。超声心动图显示一个异常的狭缝样隧道结构连接升主动脉和左心室，在舒张期有血液从主动脉流向左心室。主肺动脉观察到瓣膜上膜性狭窄。基于这些发现，该犬被诊断为 ALVT 和 I 型主动脉瓣上肺动脉瓣狭窄。

结论

这是兽医领域首例描述 ALVT 诊断成像发现的病例报告。在有主动脉瓣反流杂音的犬中应考虑 ALVT，并可通过超声心动图检测到。
