Systemic （Psys） and pulmonary （Ppa）

Systemic （Psys） and pulmonary （Ppa） arterial pressures, andpulmonary capillary wedge （Pcw） pressure should be monitored closely. Systolic unloading is associated with:（1）decreased peak systolic pressure, （2）increased stroke volume and cardiac output （CO）, and （3）decreased pulmonary capillary wedge pressure. In mitral regurgitation, regurgitant volume nd the size of the regurgitant “V” wave are reduced. In patients with ventricular septal defect, the magnitude of the left to right shunt diminishes andsystemic output increases. Changes in CO and systemic ascular resistance should be checked periodically to determine the need for alteration of pharmaacologic support. Frequent evaluation of the diastilic augmentation qnd thetiming of balloon infltion and deflation is necessary to ensure optimal effect of balloon complications is mandatory.
