STUDY OBJECTIVES This study sought to evaluate the pathophysiology of left and right heart failure in patients with chronic thromboembolic pulmonary hypertension (CTEPH) who were hospitalized to undergo pulmonary thromboendarterectomy (PTE). DESIGN Thirty-nine patients (16 women and 23 men; mean +/- SD age, 55+/-12 years) with severe CTEPH were examined before and 13+/-8 days after PTE by way...
Background. Previous studies have reported an important role forright ventricular function in the pathophysiology of the low cardiac output state that can accompany right ventricular infarction. Some studies have suggested that right ventricular distensibility impairs right ventricular filling and stroke output; others have demonstrated that the pericardium can mediate depressed left ventricula...
AIMS This study uses pulsed Doppler tissue imaging to analyse right ventricular myocardial function and its interaction with left ventricle in hypertrophic cardiomyopathy involving ventricular septum. METHODS AND RESULTS Thirty-four patients with septal hypertrophic cardiomyopathy and 30 normal subjects, comparable for sex, age, body mass index and heart rate, underwent complete standard Dopp...
The phenomenon of negative right ventricular diastolic pressure immediately after operation for relief of isolated pulmonary valve stenosis was investigated in 11 patients. Pressures in the right ventricle and pulmonary artery were measured with a catheter tip micromanometer. One patient had a negative right ventricular diastolic pressure before operation. At the end of operation right ventricu...
