The aim of the present study was to determine whether there is a relationship between coronary artery disease and pulmonary hypertension and whether pulmonary hypertension is an additional risk factor for the presence and extent of coronary artery disease in patients with chronic obstructive pulmonary disease. Patients diagnosed with chronic obstructive pulmonary disease and pulmonary hypertens...

PURPOSE The purpose of this study was to determine the normal range of the main pulmonary artery diameter (MPAD) by computed tomography (CT) in persons with normal pulmonary artery pressure, and then to evaluate the relationship of the diameter with age, gender, and body surface area (BSA). MATERIALS AND METHODS Between October 2005 and June 2007, among patients who had previously undergone a...

A2-month-old infant with a double-outlet right ventricle, pulmonary stenosis, a subaortic ventricular septal defect, a hypoplastic mitral valve, a hypoplastic left ventricle, and a restrictive atrial septal defect was seen at an outside institution. The initial plan was to palliate the child with an atrial septectomy, have the pulmonary artery oversewn, and perform a modified Blalock-Taussig sh...

Pulmonary arteries exhibit a marked vasoconstriction when exposed to hypoxic conditions. Although this may be an adaptive response to match lung ventilation with perfusion, the potential consequences of sustained pulmonary vasoconstriction include pulmonary hypertension and right heart failure. Concomitant production of proinflammatory mediators during hypoxia may exacerbate acute increases in ...

angina or heart failure [4]. CT angiography can detect the ALADAPA. The usual treatment comprises surgical correction by CABG or rerouting through an aorto-pulmonary window (Takeuchi procedure). Here, CABG was required because of the combination of atherosclerotic stenosis and ALADAPA. The long-term outcome after revascularization is excellent [5]. We report an original case of coronary artery ...
