Congenital coronary-pulmonary arterial shunt in a German shepherd dog: Diagnosis and surgical correction☆
Section snippets
Discussion
Coronary shunts are rare congenital or acquired coronary malformations, which can originate from one of the main coronary arteries and connect to a cardiac chamber (coronary-cameral shunt) or a great vessel (coronary arteriovenous shunt), bypassing the normal coronary capillary network. Most commonly, these conditions are described as coronary arterial-venous shunts (CAVS) and are considered central arteriovenous malformations, in contrast to peripheral arteriovenous shunts of the limbs or

Novel coronary artery anomaly in a French bulldog with pulmonary stenosis
2021, Journal of Veterinary CardiologyEvaluation of non-ECG and ECG-gated computed tomographic angiography for three-dimensional printing of anomalous coronary arteries in dogs with pulmonic stenosis
2019, Journal of Veterinary CardiologyCitation Excerpt :Additional rare congenital and acquired coronary artery abnormalities have been reported in dogs [8–10]. Abnormal congenital coronary connections include a right coronary artery to right atrium fistula [11] and a left coronary artery to pulmonary artery shunt [12]. Variations in the path or branching pattern of the coronary arteries have been described, but in the absence of pulmonic stenosis or when no prepulmonic coronary artery course is present, these variations are suspected to be of no clinical significance and may represent inconsequential anatomic variations.
Coronary arteriovenous malformation in a dog with a complex arrhythmia and hypothyroidism
2019, Journal of Veterinary CardiologyCitation Excerpt :In humans, CAFs are most commonly single [16,17], although multiple CAFs have been reported [16,18], and there are some reports that are more consistent with CAVM in the true sense of the definition [11,19,20]. In dogs, reports consist of a single coronary to pulmonary fistula in a German shepherd dog [21] and multiple coronary to pulmonary fistulae in an English bulldog [22]. An observation was also made by Scansen [22] that coronary to pulmonary fistulas are more often seen in association with larger thoracic arteriovenous malformations.

2016, Journal of Veterinary CardiologyCitation Excerpt :Pelosi et al [4]. have described, in another case report, the closure by surgical ligation, of a congenital aortopulmonary fistula in a dog [4]. Nakata et al. reported a transarterial coil embolization of an abdominal aortocaval fistula in a dog [25].
Single left coronary ostium and an anomalous prepulmonic right coronary artery in 2 dogs with congenital pulmonary valve stenosis
2013, Journal of Veterinary CardiologyCitation Excerpt :Compared to humans, reports of congenital CA anomalies in the dog are sparse, likely because of lack of indications for imaging the CAs. Reported congenital CA anomalies in the dog include a coronary-pulmonary arterial shunt in a young German shepherd dog with a continuous heart murmur,11 an anomalous origin of the left CA from the PA in a 2-year-old miniature poodle that died suddenly,12 and the more frequently recognized single right coronary ostium with an anomalous prepulmonic left CA first reported in 1959 in a necropsy study of an asymptomatic mongrel dog13 and later recognized in a Keeshond embryo with persistent truncus arteriosus.14 In 1965, Buchanan and Patterson15 fully described this CA anomaly, so-called “type R2A,” contributing to PS that is especially prevalent in the English bulldog.1,3,4,7,16–19
