Ventricular response to a pressure load. Left ventricular function curves in intact animal.
• The normal left ventricular response to progressive proximal aortic obstruction has three phases: (1) a phase of complete compensation in which, following transitory elevations of end-diastolic ventricular pressure (EDVT) and end-diastolic ventricular volume (EDVV), the peak ventricular pressure (PVP) is increased and cardiac output is maintained though end-diastolic ventricular pressure and ...
متن کاملSystemic Blood Pressure Response to Changes in Right Ventricular Function.
• Previous investigations have described areas in the circulation which, when appropriately stimulated, induce changes in total peripheral vascular resistance." Such receptor areas have been demonstrated in vessels of the lesser and greater circulation and three of the heart chambers. Whether similar vascular reflexes can originate in the right ventricle has been questioned. Although increasing...
متن کاملQuantitative analysis of cardiac hypertrophy due to pressure load in reference to the relations of blood pressure, left ventricular weight and left ventricular capacity.
In almost all of the cases of cardiac hypertrophy due to sustained hypertension, left ventricular capacity is increased in proportion to increased left ventricular weight, even in the absence of manifest cardiac insufficiency. The condition is regarded as the general expression of cardiac response to pressure load, and the concept of "isomorphic hypertrophy" is proposed. Concentric hypertrophy ...
متن کاملAdverse ventricular–ventricular interactions in right ventricular pressure load: Insights from pediatric pulmonary hypertension versus pulmonary stenosis
Right ventricular (RV) pressure overload has a vastly different clinical course in children with idiopathic pulmonary arterial hypertension (iPAH) than in children with pulmonary stenosis (PS). While RV function is well recognized as a key prognostic factor in iPAH, adverse ventricular-ventricular interactions and LV dysfunction are less well characterized and the pathophysiology is incompletel...
متن کاملAORTO-LEFT VENTRICULAR TUNNEL. A CASE REPORT WITH AORTIC PRESSURE AND ECHOCARDIOGRAPHIC FINDINGS
A seven-year-old girl with clinical diagnosis of aortic insufficiency underwent echocardiographic and hemodynamic evaluation and referred for surgery with the same diagnosis. However, at surgery, aorto-Ieft ventricular tunnel was found and repaired successfully. Review of echocardiogram and catheterization data revealed interesting findings to differentiate this rare entity from congenital...
