Cavalier ırkı bir köpekte cor triatriatum’u taklit eden atrial septal anevrizma

Abstract

Atrial septal anevrizma, interatrial septumun bir kalp siklusu süresince değişken yönlerde yönelimini ifade eden nadir bir deformitedir. 9 yaşlı, Cavalier ırkı köpek küçük hayvan hastanemize, akut olarak başlayan respiratorik güçlük ve abdominal genişleme şikayetleriyle getirildi. Hastaya rutin kan analizleri, elektrokardiyografi ve toraks radyografileri uygulandı. Ekokardiyografik muayenede mitral kapak hastalığı ile triküspid orifis ve sağ atrium içine doğru interatrial septum boyunca prolabe olmuş septal anevrizmanın eşlik ettiği şiddetli sol atrial dilatasyonu ortaya koydu. Renkli Doppler ile sol-sağ şant akımlı atrial septal defekt belirlendi. Hasta 2 hafta sonra aniden hayatını kaybetti. Hasta sahibi postmortem muayeneyi kabul etmedi. Yazarların bilgisine göre; bu olgu, bir köpekte atrial septal defektin eşlik ettiği ilk atrial septal anevrizma raporudur. Bu olgu ile Cavalier ırkı bir köpekte, mitral kapak hastalığının olası komplikasyonu olarak atrial septal anevrizmanın vurgulanması amaçlanmıştır

Cavalier ırkı bir köpekte cor triatriatum’u taklit eden atrial septal anevrizma

Abstract

Atrial septal aneurysm is a rare deformity of interatrial septum extending to changeable directions during cardiac cycle. A 9 year old Cavalier King Charles Spaniel referred to Small Animal Hospital with a history of acute onset of respiratoric distress and abdominal distension. Routin blood work, electrocardiography and thorax radiography were performed. Echocardiography revealed mitral valve disease and severe left atrial dilatation with an atrial septal aneurysm as a bulging of interatrial septum into the right atrium and nearly prolapsing into the tricuspid orifice. Color flow Doppler revealed a left-to-right shunt flow atrial septal defect. The dog died suddenly 2 weeks later. The owner declined postmortem examination. To the best of authors’ knowledge, this was the first report of atrial septal aneurysm with concomitant atrial septal defect in a dog. The purpose of this case report is to point out atrial septal aneurysm as the possible complication of mitral valve disease in a Cavalier King Charles Spaniel
