Reversibilität von Veränderungen der links- und rechtsventrikulären Geometrie und Hämodynamik bei pulmonaler Hypertonie. Echokardiographische Charakterisierung bei Patienten vor und nach pulmonaler Thrombendarteriektomie (Reversibility of changes in left- and right ventricular geometry and hemodynamics in patients with pulmonary hypertension. Echocardiographic characteristics before and after pulmonary thrombendarterectomy)
Abstract:Pulmonary thromboendarterectomy (PTE) leads to an acute decrease of right ventricular (RV) afterload in patients with chronic thromboembolic pulmonary hypertension. We investigated the changes in right and left ventricular (LV) geometry and hemodynamics by means of transthoracic echocardiography. The prospective study was performed in 14 patients (8 female, 6 male; age 55 +/- 20 years) before and 18 +/- 12 days after PTE. Total pulmonary vascular resistance and systolic pulmonary artery pressure were significa… Show more
