“…In the dogs with normal coronary anatomy, a levophase right‐ventricular angiogram, while dilute offered an additional assessment of coronary anatomy without arterial vascular access by a cut‐down approach. Previous studies have reported that electrocardiographic‐gated CT angiography could provide excellent anatomic assessment of normal and abnormal coronary arteries . While not of the same quality as previous electrocardiographic‐gated images, the non‐electrocardiographic‐gated CT angiography images gathered in this study were of diagnostic quality to make an anatomic determination of the coronary ostia.…”

Coronary artery anomalies have been reported in Bulldogs and present an increased risk when performing balloon valvuloplasty. Identification of coronary anomalies has been reported using multidetector‐row computed tomographic (MDCT) angiography with electrocardiographic gating. However, the utility of non‐electrocardiographic‐gated 16‐row computed tomographic for MDCT for the identification of coronary artery anatomy or anomalies to the authors’ knowledge has not been fully investigated. The purpose of this study was to evaluate the feasibility of non‐electrocardiographic‐gated computed tomographic (CT) angiography to identify coronary anomalies in Bulldogs with pulmonary valve stenosis. In this prospective, observational study, Bulldogs with echocardiographically diagnosed pulmonary valve stenosis, an echocardiographically derived transpulmonic pressure gradient >70 mm Hg, and a clinician recommendation for balloon valvuloplasty were included. Anesthetized dogs underwent a 16‐row MDCT non‐electrocardiographic‐gated CT angiography. A board‐certified veterinary radiologist and board‐certified veterinary cardiologist reviewed the CT angiography studies and identified the coronary artery anatomy. When normal coronary artery anatomy was detected on CT angiography, a right ventricular outflow tract fluoroscopic angiogram was performed and evaluated during levophase to confirm normal coronary anatomy prior to balloon valvuloplasty. Dogs with coronary anomalies noted on CT angiography were recovered from anesthesia and balloon valvuloplasty was not performed. All dogs (10/10; 100%) had interpretable images from the non‐electrocardiographic‐gated CT angiography. Coronary anomalies were identified in six dogs based on non‐electrocardiographic‐gated CT angiography, five with type R2A anomaly and one had a single left coronary ostium. Four dogs had normal coronary anatomy based on non‐electrocardiographic‐gated CT angiography. Balloon valvuloplasty was performed without incident in these four dogs. We conclude that non‐electrocardiographic‐gated CT angiography represents a noninvasive method for diagnosing coronary anomalies in Bulldogs with pulmonary valve stenosis.

“…Later, other studies have been published describing morphological characteristics of various cardiac structures and comparing echocardiography, magnetic resonance (MR) and CT measurements [32,33]. As for humans, cardiac CT in veterinary patients has now become an increasingly utilized modality for the assessment of cardiac congenital conditions, cardiac and paracardiac masses, and pericardial diseases [34][35][36]. In clinical practice, morphological evaluation of these conditions is generally performed with non-ECG-gated CT protocols, as a part of a thoracic CT examination.…”

Computed tomography (CT) is increasingly available in veterinary practice. As for humans, CT has a tremendous potential in various clinical scenario. Oncology and traumatized dogs and cats are probably the veterinary patients that get more benefit from new CT applications. However, the most amazing progresses are in vascular and cardiac applications. The advent and rapid diffusion of advanced scanner technology (multidetector row) offer unparalleled diagnostic opportunity in daily practice for comprehensive evaluation of complex cardiovascular diseases. New skills and knowledge are necessary for radiologists and nonradiologists for understanding this revolutionary field of radiology.

BackgroundBrachycephalic dogs with pulmonary stenosis are known to have a higher incidence of concurrent coronary artery abnormalities than non‐brachycephalic breeds, which increases risk when performing balloon valvuloplasty. The use of ECG‐gated CT angiography has been reported for the evaluation of coronary arteries in normal dogs and dogs with pulmonary stenosis. The purpose of this study was to report findings of coronary artery origination and morphology of main branches using ECG‐gated CT angiography in brachycephalic dogs with pulmonary stenosis.MethodsAn ECG‐gated CT angiographic protocol was used to image coronary artery anatomy in nine brachycephalic dogs with pulmonary stenosis. Images were assessed for quality as well as coronary artery morphology by one veterinary radiologist, one veterinary cardiologist and one veterinary radiology resident.ResultsAll nine dogs had good to excellent image quality. Coronary artery anomalies were identified in three of nine dogs: one R2A anomaly, one L2A anomaly and one L2C anomaly. Two dogs were assessed to be poor balloon valvuloplasty candidates based on CT angiographic images.LimitationCoronary artery morphology was not confirmed via postmortem examination in all patients.ConclusionECG‐gated CT angiography is a minimally invasive imaging modality capable of diagnosing various coronary artery anomalies in brachycephalic dogs with pulmonary stenosis and aiding in the determination of patient candidacy for balloon valvuloplasty.
