Right ventricular diastolic impairment in patients with pulmonary arterial hypertension.
BACKGROUND The role of right ventricular (RV) diastolic stiffness in pulmonary arterial hypertension (PAH) is not well established. Therefore, we investigated the presence and possible underlying mechanisms of RV diastolic stiffness in PAH patients. METHODS AND RESULTS Single-beat RV pressure-volume analyses were performed in 21 PAH patients and 7 control subjects to study RV diastolic stiffn...
متن کاملPulmonary hypertension and right ventricular function in advanced heart failure.
Pulmonary hypertension (PH) and right ventricular (RV) dysfunction are frequently encountered in patients with advanced heart failure (HF). Both conditions aggravate prognosis and influence clinical decisions. Echocardiography is the screening tool of choice for pulmonary pressures and RV function, although invasive assessment of PH is necessary when advanced therapies are considered. Reversibi...
متن کاملCoronary flow reserve correlates with right ventricular dysfunction and predicts right heart failure in patients with pulmonary arterial hypertension
Figure 1 ROI Placement and Flow-Time-Curves. Phase contract MRI images of the CSF for a patient with scleroderma-associated PAH (mPAP 49 mmHg) during rest (top row: A, B) and adenosine-induced stress (bottom row: D, E). The red ROI is drawn around the coronary sinus, the blue ROI is placed in adjacent myocardium to correct for through-plane motion. The flow-time curves (C, F) demonstrate that n...
متن کاملPulmonary function differences in patients with chronic right heart failure secondary to pulmonary arterial hypertension and chronic left heart failure
BACKGROUND Pulmonary abnormalities are found in both chronic heart failure (CHF) and pulmonary arterial hypertension (PAH). The differences of pulmonary function in chronic left heart failure and chronic right heart failure are not fully understood. MATERIAL AND METHODS We evaluated 120 patients with stable CHF (60 with chronic left heart failure and 60 with chronic right heart failure). All ...
متن کاملApplication of centrifugal pump in right ventricular failure due to pulmonary artery hypertension. (A case report)
Background: It has not been yet developed a ost suitable method to treat right ventricular failure due to pulmonar artery hypertention resulted from ventricular arrhythia. Though some case reports about patients ready to heart transplant using left assist device or biventral assist device as bridge have been published in Journals, but nocase concerning application of centrifugal pump for treatm...
