VENTRICULAR PERFORMANCE Effects of right ventricular ischemia on left ventricular geometry and the end - diastolic pressure - volume relationship in the dog
We studied the effects of right ventricular ischemia on left ventricular three-dimensional geometry and the end-diastolic pressure-volume relationship in 16 open-chest dogs before and after pericardiectomy. Left ventricular volume was calculated from three internal dimensions measured with ultrasonic crystals. In one group of eight dogs, right coronary artery (RCA) occlusion for 2 min with the ...
متن کاملEffect of right ventricular pressure on the end-diastolic left ventricular pressure-volume relationship before and after chronic right ventricular pressure overload in dogs without pericardia.
We studied the effect of chronic right ventricular pressure overload on diastolic ventricular interdependence in dogs without pericardia, instrumented to measure left ventricular pressure, right ventricular pressure, and 3 left ventricular dimensions. We studied 12 dogs before (control) and nine dogs after 6 weeks of pulmonary artery constriction producing systolic right ventricular pressure gr...
متن کاملDiastolic Left Ventricular Pressure-Volume Relationship before and after Chronic Right Ventricular Pressure Overload in Dogs without Pericardia
We studied the effect of chronic right ventricular pressure overload on diastolic ventricular interdependence in dogs without pericardia, instrumented to measure left ventricular pressure, right ventricular pressure, and 3 left ventricular dimensions. We studied 12 dogs before (control) and nine dogs after 6 weeks of pulmonary artery constriction producing systolic right ventricular pressure 27...
متن کاملPericardial influences on ventricular filling in the conscious dog. An analysis based on pericardial pressure.
Twenty-five dogs were chronically instrumented to investigate the effects of the normal pericardium on cardiac function. Pulse-transit ultrasonic transducers were implanted to measure multiple ventricular dimensions. The pericardium was incised transversely at the base of the heart and precisely reapproximated, so as to disturb its characteristics minimally. One week later, the dogs were studie...
متن کاملPericardial modulation of right and left ventricular diastolic interaction.
We studied the effects of the right ventricle (RV) and pericardium on left ventricular (LV) diastolic pressure-volume (P-V) relations in the normothermic isolated blood-perfused dog heart. Studies were performed at a constant heart rate (atrial pacing at 120 beats/min) with a coronary perfusion pressure of 100 mm Hg. LV volume was directly controlled by an intraventricular balloon, whereas RV f...
متن کاملThe significance of the intact pericardium for cardiac performance in the dog.
The significance of the intact pericardium for cardiac performance was examined in 18 open-chest dogs. Myocardial chord lengths (MCL) in the right and left ventricle were measured simultaneously by ultrasonic crystals implanted in the myocardium of the anterior walls. In 14 dogs, the ultrasonic elements were inserted into the myocardium through needle openings in the pericardium (intact pericar...
