“…In this case, since transcatheter closure was considered unsuitable on the basis of patient size, and morphology of PDA has little impact on routine surgical ligation, angiography was not performed. Recently, contrast enhanced magnetic resonance imaging (MRI) has been reported as another method to determine the morphology of a PDA (Louvet and others 2010). It is unknown whether angiography or contrast enhanced MRI would have readily distinguished this intramural PDA from a more typical extramural Type IIB PDA.…”

A 12-week old, entire female Border terrier weighing 3·5 kg was presented for investigation of a continuous left heart base murmur. The clinical presentation and preoperative echocardiogram were consistent with a standard morphology of patent ductus arteriosus (PDA) but a discrete ductal vessel was not identified during surgical dissection. Surgery had to be abandoned due to deterioration of the patient's condition under general anaesthesia which led to cardiorespiratory arrest and death despite attempts at resuscitation. Necropsy identified a recess within the wall of the aorta communicating with the pulmonary artery via an ostium at the heart base which determined this structure as an intramural PDA. This morphology of PDA is previously unreported. This report demonstrates that an intramural PDA is not readily identifiable surgically because of the absence of a discrete ductal vessel and it is important to appreciate that unusual morphologies of PDA may occur.

“…This report also highlights the importance of appreciating that unusual morphologies of PDA may occur. A surgeon faced with this situation should be prepared to abandon surgery and consider additional investigations, such as angiography or contrast enhanced MRI (Louvet and others 2010), to determine an appropriate interventional technique.…”

Congenital heart disease is an important subset of all cardiovascular disease in dogs and cats that is present at birth and most often detected in young animals but can be diagnosed in adulthood. The range of abnormalities that can occur during development of the heart is vast incorporating simple and complex defects, varying degrees of severity and clinical presentations that include heart failure and cyanosis. While some defects do not result in morbidity in an individual animal, others cause severe clinical signs and death at a young age. Advances in imaging and expanding treatment options offer increasingly more possibilities in the diagnosis and management of congenital heart disease which is the focus of this review. The objective is to provide a broad overview of current practice and highlight key aspects to guide practitioners in their approach to congenital heart disease diagnosis and knowledge of available treatment options.

“…Magnetic resonance imaging and multidetector-row computed tomography (MDCT) are 3-dimensional, noninvasive modalities. Both have proven their capabilities for the diagnosis of PDA and persistent right aortic arch in human medicine, while reports about such investigations are rare in veterinary medicine [4-10]. However, magnetic resonance imaging has the drawback of a long image acquisition time and high cost of examination.…”

Multidetector-row computed tomography of thoracic aortic anomalies in dogs and cats: Patent ductus arteriosus and vascular rings

BackgroundDiagnosis of extracardiac intrathoracic vascular anomalies is of clinical importance, but remains challenging. Traditional imaging modalities, such as radiography, echocardiography, and angiography, are inherently limited by the difficulties of a 2-dimensional approach to a 3-dimensional object. We postulated that accurate characterization of malformations of the aorta would benefit from 3-dimensional assessment. Therefore, multidetector-row computed tomography (MDCT) was chosen as a 3-dimensional, new, and noninvasive imaging technique. The purpose of this study was to evaluate patients with 2 common diseases of the intrathoracic aorta, either patent ductus arteriosus or vascular ring anomaly, by contrast-enhanced 64-row computed tomography.ResultsElectrocardiography (ECG)-gated and thoracic nongated MDCT images were reviewed in identified cases of either a patent ductus arteriosus or vascular ring anomaly. Ductal size and morphology were determined in 6 dogs that underwent ECG-gated MDCT. Vascular ring anomalies were characterized in 7 dogs and 3 cats by ECG-gated MDCT or by a nongated thoracic standard protocol.Cardiac ECG-gated MDCT clearly displayed the morphology, length, and caliber of the patent ductus arteriosus in 6 affected dogs. Persistent right aortic arch was identified in 10 animals, 8 of which showed a coexisting aberrant left subclavian artery. A mild dilation of the proximal portion of the aberrant subclavian artery near its origin of the aorta was present in 4 dogs, and a diverticulum analogous to the human Kommerell's diverticulum was present in 2 cats.ConclusionsContrast-enhanced MDCT imaging of thoracic anomalies gives valuable information about the exact aortic arch configuration. Furthermore, MDCT was able to characterize the vascular branching patterns in dogs and cats with a persistent right aortic arch and the morphology and size of the patent ductus arteriosus in affected dogs. This additional information can be of help with regard to improved diagnoses of thoracic anomalies and the planning of surgical interventions.
