The pulmonary artery pressure (PA pressure) is a measure of the blood pressure found in the main pulmonary artery. This is measured by inserting a catheter into the main pulmonary artery. [ 13 ] : 190–191 The mean pressure is typically 9–18 mmHg, [ 14 ] and the wedge pressure measured in the left atrium may be 6–12 mmHg.
Selective pulmonary angiogram revealing significant thrombus (labelled A) causing a central obstruction in the left main pulmonary artery. Pulmonary angiography (or pulmonary arteriography,conventional pulmonary angiography, selective pulmonary angiography) is a medical fluoroscopic procedure used to visualize the pulmonary arteries and much less frequently, the pulmonary veins.

Enlargement of the right descending pulmonary artery can indirectly reflect changes of pulmonary hypertension, with a size greater than 16 mm abnormal in men and 15 mm in women. [6] Appropriate penetration of the film can be assessed by faint visualization of the thoracic spines and lung markings behind the heart. The right diaphragm is usually ...
Aortopulmonary window (APW) is a faulty connection between the aorta and the main pulmonary artery that results in a significant left-to-right shunt. [2] The aortopulmonary window is the rarest of septal defects, accounting for 0.15-0.6% of all congenital heart malformations. [4]
A CT pulmonary angiogram (CTPA) is a medical diagnostic test that employs computed tomography (CT) angiography to obtain an image of the pulmonary arteries.Its main use is to diagnose pulmonary embolism (PE). [1]
The main pulmonary trunk divides into the left and the right pulmonary artery. Pulmonary artery agenesis refers to the absence of one or both pulmonary arteries. Pulmonary artery agenesis refers to a rare congenital absence of pulmonary artery due to a malformation in the sixth aortic arch. It can occur bilaterally, with both left and right ...
The aortopulmonary space is a small space between the aortic arch and the pulmonary artery. It contains the ligamentum arteriosum , the recurrent laryngeal nerve , lymph nodes , and fatty tissue . [ 1 ]
