We report an extremely rare case of pulmonary artery dissection caused by an abrupt rupture of an aortic arch aneurysm into the pulmonary artery. An asymptomatic 80-year-old man was admitted to our hospital for elective surgical repair of aortic arch aneurysm. After admission, sudden onset of hoarseness and dyspnea developed. Echocardiography demonstrated an intimal flap in the pulmonary artery...

In a patient with pulmonary valve atresia with hypoplastic main pulmonary artery selective angiography showed absence of the central left pulmonary artery and a right pulmonary artery originating from the ascending aorta close to the left coronary artery. This unusual anatomical arrangement complicates interventional and surgical treatment.

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.

A 72-year-old man presented with right-sided pleuritic chest pain, chronic cough and weight loss. Chest x ray revealed a moderate sized pleural effusion. Chest CT showed thromboem-bolism of the right main pulmonary artery, and pleural effusion with compression atelactasis of the right lower lobe of the lung (fig 1). As the thrombus appeared suspicious, being unilateral, central and occupying th...

INTRODUCTION Coronary artery fistulas are abnormal communications between a coronary artery and a cardiac chamber or a major vessel (vena cava, pulmonary vein, pulmonary artery). They are usually diagnosed by coronary arteriography. Clinical presentations are variable depending on the type of fistula, shunt volume, site of the shunt, and presence of other cardiac conditions. CASE PRESENTATION...

A 30 years old male patient was referred to our hospital with a diagnosis of pulmonary thromboembolism due to thorax-computerized tomography (CT) angiography, revealing a thrombus totally occluding left main pulmonary artery. The lesion was evaluated as tumoural mass. Positron emission tomography (PET)-CT revealed pathologic uptake at pulmonary artery mass. Due to localization of tumour, left p...

pulmonary infections, cardiac angiography found "absence" of the left pulmonary artery, but thoracic aortography demonstrated that a rudimentary patent ductus filled a distal patent pulmonary artery. There was a coexistent vascular ring with a retroesophageal right subclavian artery. At surgical exploration it was possible to mobilize the distal left puLmonary artery and perform a direct anasto...

BACKGROUND Coronary artery fistula and single coronary artery are two different rare congenital anomalies. The cases with co-existed the two anomalies are more rare. To the best of our knowledge with literature review, the coronary artery fistula between single right coronary artery and right pulmonary artery has not been previously reported. CASE PRESENTATION In the present article, we repor...

The effects of either increased pulmonary artery blood flow or pressure on the magnitude of the radius and the dynamic properties of the right pulmonary artery were studied angiographically in 162 patients during cardiac catheterization. Patients were divided into seven groups according to their hemodynamic findings. The right pulmonary artery radius was measured during systole and diastole, fr...
