Three thousand sixty-six patients underwent cardiopulmonary bypass at the Maimonides Medical Center over a 5-year period from January 1, 1987, to January 1, 1992. Of these patients, 1,890 (62%) were less than 70 years of age, 969 (32%) ranged from 70 to 79 years of age, and 207 (7%) were 80 years of age or older. The overall 30-day mortality rate was 8%.(More)
From a series of 2,594 patients undergoing open-heart surgery, 39 had sternal or costochondral infections. Most of these infections were associated with a number of predisposing factors: prolonged perfusion time, excessive postoperative bleeding, depressed cardiac output in the postoperative period, and a history of re-exploration for the control of(More)
Results of coronary artery bypass grafting with and without mitral valve replacement were analyzed retrospectively in 101 patients with preoperative ischemic mitral regurgitation to determine the effects of severity and surgical treatment of mitral regurgitation on survival. Between 1980 and 1984, a total of 1,475 patients (mean age 59, 77% male) underwent(More)
Since July, 1978, we have inserted a roller pump type of left heart assist device between the left atrium and ascending aorta in 35 patients. There were no significant complications related to use of the device. Seventeen patients recovered sufficiently to have the device removed. There were four early deaths, 60 to 120 days following removal of the device.(More)
Thirty-three patients undergoing operations on the descending thoracic or thoracoabdominal aorta were monitored to evaluate causes and effects of spinal cord ischemia as manifested by changes in somatosensory evoked potentials. Maintenance of distal aortic perfusion pressure (greater than 60 mm Hg) by either shunt or bypass techniques in 17 patients(More)
BACKGROUND Increasing concern about the transmission of viral disease has generated greater interest in the use of salvaged blood as a means of alleviating the demand for homologous blood and expediting resuscitation during massive hemorrhage. Autologous blood processed by autotransfusion devices has become increasingly common in major surgery and is now(More)
Patients undergoing open heart surgery who have had recent cardiogenic embolic stroke or have central nervous system dysfunction pose a difficult management problem. There is always the risk that cardiopulmonary bypass and heparinization may exacerbate the neurologic injury. There is no clear data indicating what is a safe interval of time from the onset of(More)
A technique of transthoracic intraaortic balloon pump insertion and a clinical experience with 14 patients is reported. The technique of transthoracic intraaortic balloon pump insertion can be done in a rapid and atraumatic fashion. A short prosthetic graft is used, and intraaortic balloon pump removal does not require resternotomy. The technique is a safe(More)
We studied both experimentally and clinically the efficacy of partial bypass techniques in maintaining spinal cord blood flow and physiological function during surgical procedures on the thoracoabdominal aorta. We attempted to define the level of distal aortic pressure required to safely ensure normal neurological function in the absence of critical(More)
