Background. Aortic root replacement remains a formidable operation. Although perioperative mortality has declined steadily, there is no consensus regarding the preferred method of reconstruction or type of composite to be used. We present our last 2 years' experience with aortic root replacement using the St. Jude Medical/Hemashield composite valve conduit.

Methods. A retrospective review of 52 consecutive patients undergoing aortic root replacement from February 1994 through October 1996 is presented. Both the open/exclusion and Cabrol methods of reconstruction were used.

Results. Thirty-one percent of the patients had undergone previous procedures of the aortic root. Thirty-seven percent required aortic arch replacement and 35% required concomitant cardiac or vascular procedures. Perioperative morbidity was low, as was perioperative mortality (3.8%). Both of the deaths that occurred were related to complications with the management of remaining thoracoabdominal aneurysms.

Conclusions. Using meticulous surgical technique and the St. Jude Medical/Hemashield composite valve conduit, one can expect low mortality and complication rates for complex aortic root reconstruction.
