Plain-English summary
An 18-month-old male Dalmatian was brought to the vet after suddenly becoming weak. During the exam, the vet found a continuous heart murmur and used ultrasound to check the heart, revealing issues with the aorta and pulmonic valve. Further tests showed a rare condition where a rupture in the aortic sinus created an abnormal connection between the aorta and the pulmonary artery. Unfortunately, this condition is serious and can be life-threatening, and the dog did not survive.

Abstract
An 18-month-old male Dalmatian dog was presented for veterinary evaluation after the pet owner observed a sudden onset of weakness. An acquired continuous cardiac murmur was detected on physical examination. Two-dimensional echocardiographic examination revealed structural abnormalities of the proximal aorta and pulmonic valve. Doppler echocardiographic studies and cardiac catheterization demonstrated the presence of a proximal aorticopulmonary shunt. A diagnosis of left aortic sinus rupture and aorticopulmonary fistula was made. Antemortem diagnosis of aortic sinus rupture in the dog has not, to our knowledge, been reported previously. The anatomical variant of left aortic sinus rupture resulting in the development of a fistula from the aorta to the main pulmonary artery is, apparently, uncommon in all species.
