MUCH has been written relative to the physiologic abnormalities produced by mitral stenosis and insufficiency. Most of the data and the concepts derived therefrom have been obtained by right heart catheterization.'--8 The introduction of left heart and combined heart catheterization9-19 has greatly enhanced the value of physiologic study in patients with rheumatic mitral valve disease and has p...

Complete drainage of the pulmonary veins into the right heart is one of the rarest and most severe congenital cardiac anomalies. The X-ray studies may suggest this diagnosis if pulmonary veins enter either coronary sinus or inferior vena cava. In the case reported, right heart catheterization and angiocardiography were used and the diagnosis of persisent left superior vena cava and partial dire...

Many studies of the pressures in the left atrium and the left ventricle of patients with mitral valve disease have been published. Initially obtained by direct puncture of the cardiac chambers at operation, such recordings have since been made possible by the development of techniques of left atrial puncture as a diagnostic procedure before operation. Direct determinations of the left atrial pr...

Methods Patients were referred for cardiovascular magnetic resonance imaging prior to LVAD placement. We assessed the association of mortality to pre-LVAD right ventricular end systolic volume index (RVESVI), right ventricular end diastolic volume index (RVEDVI), left ventricular ejection fraction (LVEF) by CMR. Right ventricular stroke work index (RVSWI) was determined by preLVAD right heart c...

The present study employed a new right-heart catheterization technique to measure pulmonary arterial pressure, pulmonary arterial wedge pressure, and pulmonary vascular resistance in anesthetized intact-chest, spontaneously breathing mice. Under fluoroscopic guidance, a specially designed catheter was inserted via the right jugular vein and advanced to the main pulmonary artery. Cardiac output ...
