Physiologic consequences of pneumonectomy. Consequences on the pulmonary function

The cardiac sequelae following pneumonectomy should be anticipated by a thorough preoperative evaluation of cardiac risk factors, and any identified significant risk should be evaluated and corrected. The most common cardiac complication following pneumonectomy is atrial dysrhythmia. The possible causes, significant correlates, and rationale for prophylaxis are discussed. With a large portion of the pulmonary vascular bed removed by pneumonectomy, the possibility and consequences of right ventricular dysfunction are outlined. Finally, the rare but catastrophic occurrence of cardiac herniation is described.
