Abstract

A 12-year-old intact female mixed dog (weighing 6.2 kg) was referred with primary complaints of severe abdominal distension, persistent coughing and exercise intolerance. Diagnostic studies found ascites, jugular distension, loud left and right apical systolic (grade 4/6) murmur, generalized cardiomegaly with caudal vena cava distension and left atrial dilation. Echocardiographic findings were consistent with degenerative mitral and tricuspid valve endocardiosis and bi-ventricular congestive heart failure. There was also a left to right shunting patent foramen ovale. The LV systolic function is depressed relative to the degree of volume overload. Based on diagnostic findings, this case was diagnosed as PFO complicated with mitral and tricuspid valve endocardiosis with ISACHC IIIa heart failure. The dog was treated with furosemide (2 mg/kg, q12hr, PO), sildenafil (1 mg/kg, q8hr, PO), pimobendan (0.3 mg/kg, q12hr, PO), enalapril (0.5 mg/kg, q12hr, PO) and spironolactone (1 mg/kg, q12hr). The clinical signs were gradually improved after medical therapy.

12연령의 암컷 잡종개 (체중 6.2 kg)가 심한 복부 팽만, 지속적 기침 그리고 운동 불내성을 주증으로 진료 의뢰 되었다. 진단상에 복수, 경정맥 노장, 심한 좌우 심첨부 수축기 잡음 (4/6 단계), 후대정맥 확장을 동반한 전반적 심비대와 좌심방 확장이 관찰되었다. 심장 초음파에서는 퇴행성 이첨판막 그리고 삼첨판막 심내막증과 양심실성 울혈성 심부전이 관찰되었다. 좌우단락의 난원공 개존증 또한 있었다. 좌심실 수축능은 용적 과부하의 정도와 관계되어 떨어져 있었다. 진단적 결과에 기초하여, 본 증례는 ISACHC IIIa 심부전의 이첨판막과 삼첨판막 심내막증이 합병된 난원공 개존증으로 진단되었다. 이 개는 푸로세마이드 (2 mg/kg, q12hr, PO), 피모벤단 (0.3 mg/kg, q12hr, PO)와 스피로노락톤 (1 mg/kg, q12hr)으로 치료되었다. 임상 증상들은 약물 치료 후에 점차적으로 개선되었다.
