Coronary arterial compression testing by simultaneous balloon valvuloplasty and coronary angiography in an English bulldog with pulmonary valve stenosis.

J Vet Cardiol 2021 Jun 2;35:124-129. Epub 2021 Apr 2.

University of Chicago, Pediatric Cardiology, Chicago, IL, USA.

A 4-year-old male neutered English bulldog presented for heart murmur evaluation. Echocardiography identified severe pulmonic stenosis (an echocardiography-derived transpulmonary pressure gradient of 100 mmHg), and computed tomography confirmed the presence of an anomalous coronary artery with a prepulmonic course of the left coronary artery arising from the right coronary ostium. Before artificial pulmonic valve implantation, a coronary compression test was performed. A simultaneous aortic root angiogram and pulmonic balloon valvuloplasty revealed complete occlusion of the circumflex branch. Artificial valve implantation was aborted with concern for fatal coronary compression after implantation. Coronary compression testing is a critical component of the evaluation before catheter-based implantation of conduits across the pulmonic valve.

Left pulmonary arterial branch interruption with concurrent coarctation of the right pulmonary artery in a dog.

J Vet Cardiol 2021 Apr 5;34:105-111. Epub 2021 Feb 5.

Chicago Pediatric Heart Center, Chicago, IL, USA.

This case report describes a rare disorder of a left pulmonary artery interruption with concurrent coarctation of the right pulmonary artery in a dog. A 5-year-old, male neutered, mixed-breed dog presented for evaluation of an asymptomatic heart murmur. Echocardiography and computed tomography revealed complete interruption of the proximal left pulmonary artery and coarctation of the right pulmonary artery. Collateral circulation to the left lung field was provided by a dilated bronchoesophageal artery with evidence of left pulmonary hypoplasia. Pulmonary artery interruption and coarctation is rarely reported in the veterinary literature.

Marked lateral ST-segment elevation with inferior ST-segment depression in an asymptomatic 12 year-old girl: A normal variant?

J Electrocardiol 2020 Jul - Aug;61:23-26. Epub 2020 May 18.

Center for Arrhythmia Care, Heart & Vascular Center, Pritzker School of Medicine of the University of Chicago, Chicago, IL, United States of America.

Significant ST-segment changes raise concern for myocardial ischemia, cardiomyopathy or myocardial inflammation and therefore, warrant an extensive and often invasive cardiovascular evaluation. We report a 12 year-old asymptomatic African-American girl with marked ST-segment elevation in leads I and aVL and ST-segment depression in inferior leads II, III and aVF. Extensive cardiovascular evaluation did not reveal any abnormality suggesting that these findings, which have previously not been reported, are likely benign, at least in this young girl.
