Plain-English summary
Three dogs were diagnosed with a serious heart condition called imperforate cor triatriatum dexter, which caused abnormal blood flow in their hearts. They also had a patent foramen ovale (a small hole in the heart) and significant pulmonic stenosis (narrowing of the heart valve). While two of the dogs showed symptoms and had surgery to redirect blood flow, the procedure was unsuccessful. The third dog was not showing any symptoms, so surgery was not performed. Unfortunately, the attempts to correct the condition did not lead to recovery for the symptomatic dogs.

Abstract
Three canines were identified with aberrant drainage of the caudal vena cava to the left atrium, consistent with imperforate cor triatriatum dexter, and concurrent patent foramen ovale. All three had concurrent significant pulmonic stenosis with varying degrees of hypoplasia of the right ventricular outflow tract. Echocardiography, positive contrast studies, and angiography confirmed the diagnosis. Surgical redirection of the caudal vena cava bloodflow to the right atrium was attempted unsuccessfully in two symptomatic patients. The third patient was asymptomatic, and correction was not attempted. Possible embryologic causes and possible approaches in future cases are discussed.
