BACKGROUND Exercise capacity is impaired in pulmonary arterial hypertension (PAH). We hypothesized that cardiovascular reserve abnormalities would be associated with impaired hemodynamic response to pharmacological stress and worse outcome in PAH. METHODS Eighteen PAH patients (p) group 1 NYHA class II/III and ten controls underwent simultaneous right… (More)
Pulmonary arterial hypertension (PAH) is a rare fatal disease defined as a sustained elevation of pulmonary arterial pressure to more than 25 mmHg at rest, with a mean pulmonary-capillary wedge pressure and left ventricular enddiastolic pressure of less than 15 mmHg at rest. Histopathology of PAH is founded on structural modifications on the vascular wall… (More)
BACKGROUND The aim is to correlate pulmonary arterial (PA) remodeling estimated by PA fibrosis in PA hypertension (PAH) with clinical follow-up. Histology of PA specimens is also performed. METHODS 19 patients, aged 54±16 (4 men), functional class II-III were studied with right heart catheterization, PA Intravascular Ultrasound and optical coherence… (More)
Lung transplant patients have an increased risk of pulmonary embolism which is often associated with hypercoagulability disorders. We present a case of sudden death resulting from pulmonary intravascular platelet thromboembolism following a single-lung transplant.
