Presentation
Presents with abdominal distension and heart murmur. Recent surgery performed to ligate a patent ductus arteriosus.
Patient Data
The heart is moderately enlarged predominantly on the right side. The pulmonary arteries and veins appear mildly distended. There is increased opacity in the region of the aorta and main pulmonary artery on the dorsoventral projection. The caudal vena cava is enlarged and slightly tortuous on both projections. There is poor peritoneal detail and abdominal distention. The pulmonary parenchyma is normal. There is a soft tissue swelling on the left thoracic wall consistent with recent surgery.
Case Discussion
The radiographic findings indicate right heart failure due to congenital cardiac anomaly, such as cor triatriatum dexter. Mild pulmonary overcirculation may be secondary to previous PDA. Right-sided cardiomegaly due to pulmonic stenosis. These are congenital cardiac anomalies.
Echocardiography showed multiple congenital cardiac anomalies.
Cor triatriatum dexter. A membrane separating the right atrium into two chambers was seen on echocardiogram. This was corrected with balloon dilation.
Moderate pulmonic stenosis
Adequate ligation of the PDA with minimal residual flow
