Victor Pretorius, MBchB Division of Cardiothoracic Surgery University of California San Diego La Jolla, CA Chronic thromboembolic pulmonary hypertension (CTEPH) is defined as a mean pulmonary artery pressure 25 mm Hg and pulmonary artery wedge pressure 15 mm Hg in the presence of occlusive thrombi within the pulmonary arteries. Surgical pulmonary thromboendarterectomy (PTE) is considered the be...
The aim of our prospective multicentric study was to develop a screening method for pulmonary hypertension in patients with chronic lung diseases. We investigated 710 patients in 10 hospitals: 315 males and 109 females with chronic obstructive pulmonary disease, and 286 males with silicosis. Manifest pulmonary hypertension was defined as pulmonary artery pressure greater than 20 mmHg (2.7 kPa) ...
Background: Neurofibromatosis type1 (NF-1) is a hereditary autosomal dominant disease that is accompanied by complications, such as benign and malignant tumors and vascular involvement, including pulmonary hypertension, artery stenosis, and pulmonary artery aneurysm. Spontaneous hemothorax is a rare and lethal complication of NF-1 due to vasculopathy as stenosis or aneurysmal modifications of l...
Pulmonary tumor embolism is a rare syndrome caused by migration of tumoral emboli into the pulmonary arteries. These tumor emboli may form a fibrin-platelet thrombi, resulting in pulmonary-artery hypertension and subsequent right-heart failure. Establishing this diagnosis can be very difficult, and most cases are diagnosed during autopsy,1 although a history of cancer may be a predictor. We rep...
The effects of either increased pulmonary artery blood flow or pressure on the magnitude of the radius and the dynamic properties of the right pulmonary artery were studied angiographically in 162 patients during cardiac catheterization. Patients were divided into seven groups according to their hemodynamic findings. The right pulmonary artery radius was measured during systole and diastole, fr...
INTRODUCTION Disconnected pulmonary arteries are unusual and may result in pulmonary hypertension with acute right heart failure. CASE PRESENTATION We report a case of a three-month-old Asian girl who presented with heart failure and severe pulmonary hypertension due to a disconnected right pulmonary artery. An epoprostenol (prostacyclin) infusion was instrumental in lowering pulmonary artery...
