A technique of intra-aortic balloon pump insertion via the ascending aorta is useful when the femoral approach is not available and also for supporting patients whose cardiovascular system collapses during thoracotomy. In addition, this approach provides a simple method of assisting the heart and other vital organs while weaning the patient off cardiopulmonary bypass. There have been no complications noted in 25 patients treated by this method.
