Temporary epicardial left ventricular and biventricular pacing improves cardiac output after cardiopulmonary bypass
BACKGROUND To evaluate, with different pacing modes, acute changes in left ventricular systolic function, obtained by continuous cardiac output thermodilution in various subsets of patients undergoing cardiopulmonary bypass surgery. Increments of mean arterial pressure and cardiac output were considered the end point. METHODS Fifty cases electively submitted to cardiac surgery were analyzed. ...
متن کاملThe hemodynamic effect of intrinsic conduction during left ventricular pacing as compared to biventricular pacing.
OBJECTIVES We sought to investigate the effect of intrinsic conduction over the right bundle on the maximum rate of left ventricular pressure rise (LVdP/dt(max)) during left ventricular (LV) pacing compared to biventricular (BiV) pacing. BACKGROUND Simultaneous BiV pacing and LV pacing both improve LV function in patients with heart failure and LV asynchrony. We studied the hemodynamic effect...
متن کاملBiventricular mechanical asynchrony predicts hemodynamic effect of uni- and biventricular pacing.
We tested whether biventricular resynchronization explains contractile function changes with univentricular and biventricular pacing in heart failure patients with varying magnitudes of baseline biventricular asynchrony. Thirty patients (New York Hospital Association class > or = III, QRS duration > or =120 ms) were tested. Contractile function was measured by left ventricular maximum first der...
متن کاملHypoxaemia during cardiopulmonary bypass.
For cardiopulmonary bypass during open-heart surgery we use a bubble oxygenator and a technique of haemodilution and moderate hypothermia. During the course of routine perfusion we have observed arterial desaturation in a number of patients and in five patients the desaturation was marked (SaO2<85%)'. The low arterial oxygen saturations occurred mainly in the rewarming period. This report is of...
متن کاملLung injury after cardiopulmonary bypass.
Pulmonary injury during cardiopulmonary bypass is common as patient factors (smoking, pain, pneumonia) and the effects of cardiopulmonary bypass combine to compromise lung function after cardiac surgery. Lung injury follows the propagation of an inflammatory response involving cytokines, complement, neutrophils, monocytes, activated endothelial cells and platelets. Neutrophils sequester in the ...
