Plain-English summary
Three dogs were brought to the vet because their owners noticed heart murmurs. After testing, they were found to have abnormal blood vessels called arteriovenous shunts, which can mimic a condition known as patent ductus arteriosus (PDA). The vets used ultrasound to see the blood flow and confirmed there was no PDA, but they did find these unusual shunts connecting the aorta to the lungs. Recognizing these shunts is important when a soft, continuous heart murmur is detected.

Abstract
Three dogs presented for the evaluation of cardiac murmurs were diagnosed with aberrant arteriovenous shunts. All cases demonstrated the following findings: 1) relatively soft continuous murmur loudest at the left heart base resembling patent ductus arteriosus (PDA); 2) shunt flow signals in the pulmonary artery on echocardiography; and 3) no PDA on selective angiography, but evidence of anomalous shunting vessels from thoracic aorta to pulmonary vasculature. An aberrant arteriovenous shunt should be considered when a continuous murmur of relatively small intensity is heard.
