Abstract

A 4-years-old, intact male Golden retriever dog was presented with abdominal distension and dyspnea. Physical examination revealed arrhythmia and cardiac murmur. Generalized cardiomegaly, pleural effusion and ascites were shown on thoracic and abdominal radiographs. Two-dimensional echocardiography revealed abnormal mitral and tricuspid valve motion, mitral and tricuspid regurgitation, left ventricular eccentric hypertrophy and left atrial dilation. Color-flow Doppler imaging revealed turbulent flow extending into the left ventricle during diastole from the mitral valve orifice, and into the left atrium during systole. Spectral Doppler recordings revealed highly increased early diastolic mitral valve inflow and prolonged pressure half-time of mitral inflow. Based on the echocardiographic examination, the diagnosis was made as the mitral valve dysplasia concurrent with mitral valve stenosis and tricuspid valve dysplasia.

4년령의 수컷 골든 리트리버 견이 복부 팽만 및 호흡곤란을 주증상으로 내원하였으며, 신체 검사 결과 부정맥과 심잡음이 청진되었다. 흉복부 방사선 검사 결과 전반적인 심비대, 흉수 및 복수가 관찰되었다. 심초음파 검사에서 비정상적인 승모판 및 삼첨판의 움직임과 역류가 관찰되었으며, 좌심실의 편심성 비대와 좌심방 비대가 보였다. 컬러 도플러 영상에서 확장기에 승모판 입구로부터 좌심실로 유입되는 와류가 관찰되었으며, 수축기에는 좌심방 및 우심방으로의 와류가 보였다. 도플러 검사로 확장기 승모판 유입 속도가 매우 증가하였으며 pressure half time이 지연되었다는 것을 알 수 있었다. 심초음파 검사 결과에 기초하여 승모판 협착증과 병발된 승모판 이형성증과 삼첨판 이형성증을 진단하였다.
