Pulmonary artery catheter is frequently used to monitor patients during liver transplantation. Recently developed less invasive methods for estimating cardiac output and pulmonary capillary wedge pressure together with the failure of randomized studies to demonstrate reduced mortality in pulmonary artery catheter-monitored patients, has restricted its applicability. Pulmonary artery rupture by ...

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 pulmonary artery hypertension is the presentation of various types of cardiovascular and systematic diseases. there are different kinds of noninvasive methods to determine right ventricular function, pulmonary artery pressure, and effect of pulmonary hypertension on right ventricular function. these methods include the tissue doppler imaging (tdi) of the tricuspid annulus and the lon...

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...

BACKGROUND Pulmonary arterial hypertension is a devastating disease with high morbidity and mortality and limited treatment options. Recent studies have shown that pulmonary artery denervation improves pulmonary hemodynamics in an experimental model and in an early clinical trial. We aimed to evaluate the nerve distribution around the pulmonary artery, to determine the effect of radiofrequency ...

the radiologic features of intralobar pulmonary sequestration (ilps) have been describe and include the identification of a feeding systemic artery with venous drainage through pulmonary veins. primary sequestration associated with typical hamartoma signs is really rare and has been described only once. we describe a patient with ilps whose radiographic findings were unusual for two reasons. fi...

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...

Six patients with anomalous origin of one pulmonary artery from the ascending aorta were reviewed. Four had anomalous origin of the right pulmonary artery and two had anomalous origin of the left pulmonary artery from the ascending aorta. Two of these six patients had tetralogy of Fallot. Two patients died in the first month of life. No changes in the pulmonary vasculature were seen at necropsy...
