lüll Right ventricular function and failure: a review Hines RYale J Biol Med 1991[Jul]; 64 (4): 295-307The importance of right ventricular (RV) function in maintaining global cardiac performance is the focus of this discussion. The physiological determinants of normal right ventricular function will be discussed, with particular emphasis on the afterload and contractility characteristics of the right ventricle. Numerous clinical conditions have been shown to affect RV performance. These conditions include positive-pressure ventilation, ischemia, pulmonary hypertension, and cardiac surgery. Present methods for the perioperative evaluation of RV function include angiography, radionuclide techniques, thermodilution techniques, echocardiography, and magnetic resonance imaging. Traditional modalities for the treatment of RV dysfunction consist of pharmacological interventions (i.e., vasodilators and inotropes) and/or mechanical assist devices. Newer pharmacological strategies for the treatment of RV failure and associated pulmonary hypertension include the phosphodiesterase fraction III inhibitors and the prostaglandins, specifically PGE1. In summary, the accurate evaluation of perioperative RV performance combined with new treatment options will ensure maximal preservation of RV performance.|*Ventricular Function[MESH]|*Ventricular Function, Right[MESH]|Angiography[MESH]|Animals[MESH]|Cardiac Volume[MESH]|Dogs[MESH]|Echocardiography[MESH]|Heart Failure/*diagnosis/drug therapy/therapy[MESH]|Heart Function Tests[MESH]|Heart Septum/physiology[MESH]|Heart Ventricles/pathology[MESH]|Humans[MESH]|Magnetic Resonance Imaging[MESH]|Radionuclide Ventriculography[MESH]|Thermodilution[MESH] |
