Abstract
Background: The hemodynamic criteria for PAH is a pulmonary capillary wedge pressure of below fifteen millimeters Hg and a pulmonary vascular resistance (PVR) of higher than two Wood Units (WU), in addition to a mean pulmonary artery pressure of above twenty millimeters Hg. Because of its accessibility, non-invasiveness, and reproducibility, echocardiography is routinely employed in the diagnosis and monitoring of therapy for cases with PH. Aim: to correlate between the pulmonary artery diameter and its ratio to the aortic diameter in CT chest and the right ventricular (RV) function measured by echocardiography (Echo) in cases with pulmonary hypertension (PH). Patients and Methods: This non-randomized interventional research performed in Maadi and Kobri Elkoba at the Armed Forces Medical Complex. One hundred individuals with RVSP more than 36 mm Hg were analyzed. Results: RVSP positively correlated with pulmonary artery (PA) diameter, P/A ratio and MPI. TAPSI negatively correlated with PA diameter, RVSP and MPI. Conclusion: Impaired RV function occurs more with increased RVSP and increased pulmonary artery diameter in CT chest, PA diameter & P/A ratio in CT chest is correlated with RVSP and TAPSE.
