Double‐outlet right ventricle associated with discordant atrioventricular connection and dextrocardia in a cat

Abstract

The prevalence of congenital cardiac disease in cats varies from 0.2 to 1 per cent, with males being more affected than females. This is probably an underestimate due to the fact that not all affected kittens are presented. Discordant atrioventricular connection (where the morphological right atrium connects to the morphological left ventricle, and the morphological left atrium connects to the morphological right ventricle) is an uncommon condition in humans and, to the authors' knowledge, has not to date been described in animals. The association between this anomaly and the double-outlet right ventricle (where both great arteries arise entirely or partially from the morphological right ventricle) is extremely rare in children. This report describes a case of a cat which presented with this association of cardiac defects.

Double-Outlet Right Ventricle in an Angus Calf

“…10 There are few reports of DORV in domestic animals and this defect is assumed to be rare. [3][4][5][6][7][8][9] The prognosis for DORV in animals appears to be poor but one successful surgical repair of DORV has been reported in a cat. 4 The antemortem distinction between DORV from other conotruncal abnormalities such as the tetralogy of Fallot and complete transposition of the great vessels is made difficult because of the common embryologic origin and close relationship of these defects.…”

Dextrocardia in Short-Nosed Fruit Bats (Cynopterus sphinx) and Their Relative Heart Masses

“…This cardiac positional anomaly is known as dextrocardia (Mahendrakar and Seth, 2004) which is a congenital heart disease with a low incidence rate of around one in 12,000 pregnant women (Bohun et al, 2007). To the best of our knowledge, although de x tro cardia has been described in domestic animals such as dog (Carrig et al, 1974) and cat (Abduch et al, 2003), it has not been found in any wild mammal population. In this paper, we report the first case of dextrocardia in bats (order Chiroptera).…”

“…Beim Menschen zählt der DORV zu den seltenen Defekten mit 0,03 bis 0,14 pro 1000 Geburten (13,18,20,31,33). In der veterinärmedizinischen Literatur finden sich Beschreibungen eines DORV bei verschiedenen Tierarten wie Katze (1,21,30,40), Hund (24,39), Rind (15,32,43,44) und Pferd (8), wobei es sich in erster Linie um Fallberichte handelt. Die Prävalenz kongenitaler Herzerkrankungen beim Kalb wurde in einer Studie an Feten mit 0,7 % ermittelt (22).…”
