Right ventricular pressure-volume relations and effects of selective vena cava occlusion during cardiopulmonary resuscitation. [PDF]
PLoS ONEObjectivesTo investigate right ventricular hemodynamics and determine how vena cava occlusion (VCO) influences right ventricular pressure-volume dynamics during cardiopulmonary resuscitation (CPR).MethodsWe used a swine model of electrically induced ...

Postextrasystolic Ventricular Pressure Responses [PDF]
Circulation, 1971 The peak postextrasystolic ventricular pressure was examined in tracings obtained during routine catheterization of the right and left ventricles in 252 cases. The invariable response in the apparently "normal" left ventricle was a fall or no change in peak systolic pressure, whereas in the obstructed left ventricle, the failed left ventricle, the ...

Human Stem Cell–Derived Cardiomyocytes Integrate Into the Heart of Monkeys With Right Ventricular Pressure Overload [PDF]
Cell TransplantationCardiac ventricular pressure overload affects patients with congenital heart defects and can cause cardiac insufficiency. Grafts of stem cell–derived cardiomyocytes are proposed as a complementary treatment to surgical repair of the cardiac defect ...

Pericardial and Ventricular Pressure [PDF]
Circulation Research, 1960 In anesthetized open-chest and closed-chest dogs subjected to plethora and hemorrhage, pressures were measured simultaneously in the right atrium, right and left ventricles, and the pleural and pericardial spaces. It was found that an increase in ventricular end-diastolic pressure above approximately 1 mm.

Mitigating effect of tanshinone IIA on ventricular remodeling in rats with pressure overload-induced heart failure [PDF]
Acta Cirúrgica Brasileira, 2019 Purpose To investigate the effect of tanshinone IIA (TIIA) on ventricular remodeling in rats with pressure overload-induced heart failure. Methods Pressure overload-induced heart failure model (abdominal aortic coarctation) was established in 40 rats ...

Levosimendan, milrinone, and dobutamine in experimental acute pulmonary embolism
Pulmonary Circulation, 2021 Acute pulmonary embolism is a frequent condition in emergency medicine and potentially fatal. Cause of death is right ventricular failure due to increased right ventricular afterload from both pulmonary vascular obstruction and vasoconstriction ...
