Case ReportsIntraoperative hemodialysis during cardiopulmonary bypass in chronic renal failure.
This report describes the features and the course of a patient on maintenance hemodialysis in whom infective endocarditis of the aortic valve ensued. The subsequent development of intractable congestive heart failure necessitated aortic valve replacement. Use of intraoperative hemodialysis, facilitating the intraoperative and postoperative management of the patient, is described. Following valve replacement the patient did well with no evidence of congestive heart failure.

Case ReportsRunaway pump head: new cause of gas embolism during cardiopulmonary bypass.
Massive gas embolism was narrowly avoided during a recent case of cardiopulmonary bypass for aortic valve replacement. Cause of the mishap was an arterial pump head that had rapidly accelerated spontaneously, emptying the oxygenator of blood within seconds. No gas entered the patient's vascular system, but a period of circulatory arrest was required in order to purge the extracorporeal circuit of gas and to re-establish blood flow. Only an instantaneous response by the perfusionist prevented massive gas embolism.

A 59-year-old man underwent resection of aneurysm of the descending thoracic aorta with graft replacement. A postoperative chylothorax was managed by nonsurgical means and subsided. ⋯ This was found to be a chylous pseudocyst. Management of chylothorax and the details of this unique case are described.

Case ReportsTricuspid valvular incompetence and rupture of the ventricular septum caused by nonpenetrating trauma.
A young adult involved in an automobile accident had tricuspid valvular incompetence and rupture of the ventricular septum owing to blunt trauma. He had a successful repair of the ventricular septal defect and replacement of the tricuspid valve. ⋯ Rupture of the membranous portion of the ventricular spetum is extremely rare. This is the first report of a patient having a combination of these lesions.
