Primary pulmonary hypertension is often associated with angina-like chest pain of uncertain etiology. Left main coronary artery compression by the pulmonary artery is a treatable cause of angina and should be considered in these patients. We describe a patient presenting with primary pulmonary hypertension, clinical angina and extrinsic compression of the left main coronary artery by the pulmon...

BACKGROUND This study was undertaken to determine outcomes and best strategies for treatment of occluded pulmonary arteries in patients with congenital heart disease. METHODS AND RESULTS Between 1998 and 2002, occlusion of a previously patent pulmonary artery was established in 23 patients. Data were obtained retrospectively. Diagnoses were pulmonary atresia and ventricular septal defect in 1...

Pulmonary hypertension is a hemodynamic and pathophysiological condition defined as an increase in mean pulmonary pressure more than or equal to 25 mm Hg. Risk stratification and prognostic evaluation in patients with pulmonary hypertension are complex and require multiple investigations. There is a lack of consensus on factors that predict mortality and prognosis in patients with pulmonary art...

Anatomic variations of the pulmonary artery increase the risks for vessel injury and critical mistakes during pulmonary artery resection. A patient who underwent left lower lobectomy for lung cancer with a mediastinal lingular and basal pulmonary artery that had been detected preoperatively by three-dimensional computed tomography is presented. During thoracoscopic surgery, the mediastinal basa...

The two main sources of blood supply to the lungs and their supporting structures are the pulmonary and bronchial arteries. The bronchial arteries account for 1% of the cardiac output but can be recruited to provide additional systemic circulation to the lungs in various acquired and congenital thoracic disorders. An understanding of bronchial artery anatomy and function is important in the ide...

introduction: to assess the efficacy and safety of bronchial artery embolization in the treatment of massive hemoptysis.   materials and methods: a retrospective study on 46 patients (26 males and 20 females) who were referred to the razavi hospital from april 2009 to may 2012 with massive hemoptysis and had bronchial artery embolization procedures. general characteristics of the patients inclu...

background anomalous left coronary artery from the pulmonary artery (alcapa) is a rare congenital cardiovascular defect that occurs in approximately 1/300 000 live births or 0.5% of children with congenital heart disease. there are two types of alcapa syndrome: the infant type and the adult type. the most infants experience myocardial infarction and congestive heart failure, and approximately 9...

We present a case of pulmonary artery perforation in a patient who developed a pneumothorax after cardiac surgery. In the process of inserting a chest tube the patient became tachypnoeic, and developed haemoptysis. The trachea was intubated, and right bronchial intubation was performed with persistent bleeding. The pulmonary artery catheter was gently withdrawn and the balloon inflated, with ce...
