Plain-English summary
A one-year-old male American bulldog was brought in for severe breathing problems caused by pulmonary stenosis, a condition where the heart's outflow tract is narrowed. After tests showed extremely high pressure in the heart, the veterinarian placed a special stent to help open up the narrowed area. Remarkably, this procedure not only reduced the pressure significantly but also avoided any complications with the dog's coronary artery. Following the surgery, the dog showed improvement, and the pressure in the heart was much lower, indicating a successful outcome.

Abstract
A one-year-old male intact American bulldog was presented for evaluation of previously diagnosed pulmonary stenosis. Echocardiography identified ultra-severe stenosis with an instantaneous trans-pulmonary pressure gradient of 240 mmHg. Angiography confirmed the presence of an anomalous coronary artery with a prepulmonic course of the left coronary artery arising from a single right coronary ostium consistent with a type R2A coronary anomaly. A trans-pulmonary stent was successfully placed transvenously with diameter sizing based on coronary compression testing. No coronary compression was present on postimplantation angiography. A marked reduction in the pressure gradient was obtained on postoperative echocardiography (reduction to 68 mmHg), despite selecting a stent diameter less than the pulmonary annulus diameter. This is the first report of the use of coronary compression testing in transvenous trans-pulmonic stent implantation in a dog with a type R2A coronary artery anomaly. Selection of a stent diameter less than the pulmonary annulus diameter conveyed a clinically relevant reduction in the trans-pulmonic pressure gradient while avoiding coronary compression in this case.
