Unusual Compression of the Right Pulmonary Artery by the Aortic Arch
The Annals of Thoracic Surgery, 2014Co-Authors: Sachin Talwar, Saurabh Kumar Gupta, Subramanian Muthukkumaran, Madhan Kumar Murugan, Balram AiranAbstract:Compression of the Right Pulmonary Artery is unusual. We describe a patient with a double-outlet Right ventricle, a ventricular septal defect, and Pulmonary stenosis in whom the Right Pulmonary Artery was compressed by a Right-sided aortic arch. The condition was successfully managed during surgical correction.

Right Pulmonary Artery-to-left atrium communication: report of 5 cases.
The Annals of Thoracic Surgery, 2005Co-Authors: Ujjwal K. Chowdhury, Balram Airan, Shyam S. Kothari, Akhilesh Pandey, K. Ganapathy Subramaniam, Panangipalli VenugopalAbstract:Five patients of Right Pulmonary Artery-to-left atrium communication presented with special emphasis on the clinical presentation, anatomic variations, diagnostic considerations, and management options. An individualized management algorithm is recommended.

Right Pulmonary Artery left atrium communication
The Annals of Thoracic Surgery, 2000Co-Authors: Smruti R Mohanty, Shyam S. Kothari, Rakesh Yadav, Balram AiranAbstract:This is a collective review of 59 published cases of Right Pulmonary Artery to left atrium communication in the English-language literature. In this article, we review the literature on the clinical presentation, anatomic variations, diagnostic features, and management considerations of previously reported cases. Two-dimensional echocardiography and cardiac catheterization including selective angiography provided the necessary diagnostic information and defined the anatomy before surgery in all patients. Various management options including medical, surgical, and transcatheter closure have been reported. The lesions have been classified into four types (I, II, III, and IV) that have a bearing on the appropriate surgical approach and techniques of repair that are discussed in the text. Use of extracorporeal circulation may be considered in selected instances. The operative mortality rate during the earlier era (1950 to 1979) was high, at 22%. More recently, the mortality rate has approached zero. An individualized surgical approach depending on the type of surgical connections is recommended.

Right Pulmonary Artery occlusion secondary to a dissecting aortic aneurysm
Clinical Cardiology, 1995Co-Authors: Mary N Glass, Bruce F Waller, Joseph Fraiz, Carl J ShaarAbstract:This report describes a case of Right Pulmonary Artery obstruction caused by a dissecting aneurysm of the thoracic aorta. Initial ventilation-perfusion (V/Q) scan revealed no perfusion to the Right lung. Lack of Right lung perfusion plus other clinical abnormalities led to an initial diagnosis of massive embolism in the Right lung. Bilateral Pulmonary arteriography of the thoracic and abdominal aorta revealed extrinsic compression of the Right Pulmonary Artery near its origin and the suggestion of an ascending aortic dissection. Subsequent ascending aortography and computed tomography (CT) confirmed a dissection of the ascending aorta. Aortography in the true lumen of the aorta revealed trivial aortic insufficiency. These diagnostic procedures confirmed the presence of an acute dissecting aneurysm of the ascending aorta that caused compression of the Right Pulmonary Artery. The finding of a massive unilateral segmental defect with normal ventilation upon lung scanning does not always ensure a diagnosis of acute Pulmonary embolus. Patient presentation with massive unilateral perfusion defect merits further evaluation with Pulmonary arteriography.

coronary compression caused by stenting a Right Pulmonary Artery conduit
Catheterization and Cardiovascular Interventions, 2009Co-Authors: Marc Gewillig, S C BrownAbstract:Extrinsic compression of the left main coronary Artery is a rare and life-threatening complication of endovascular stenting of Pulmonary Artery conduits. This case report describes fatal myocardial infarction caused by compression of the left main coronary Artery due to stent placement in a stenosed Right Pulmonary Artery conduit. © 2009 Wiley-Liss, Inc.

Communication between the Right Pulmonary Artery and left atrium with aneurysm formation
General Thoracic and Cardiovascular Surgery, 2008Co-Authors: Masahide Chikada, Arata Murakami, Kou Takeuchi, Shinichi TakamotoAbstract:Communication between the Pulmonary Artery and the left atrium is a rare congenital anomaly. A 7-year-old boy was referred to our hospital with a diagnosis of Pulmonary arteriovenous fistula. Referral to a pediatric cardiologist had been delayed because he had only slight cyanosis and no heart murmur. Catheterization and computed tomography scans confirmed that the Right Pulmonary branches and Pulmonary venous returns were normal and that an additional aneurysmal communication was located between the Right Pulmonary Artery and the left atrium. Surgery proceeded uneventfully together with a cardioPulmonary bypass. The connection from the Right Pulmonary Artery to the aneurysm was ligated, and the connection from the left atrium to the aneurysm was closed with a polytetrafluoroethylene patch. We describe this rare anomaly with cyanosis and no heart murmur.
