Comparative StudyIntraoperative transoesophageal echocardiography in aortic valve surgery.
From January 1994 to May 1998, 272 patients underwent homograft aortic valve replacement (n = 139), Ross procedure (n = 100) and aortic valve repair (n = 33). Transoesophageal echocardiography was performed intraoperatively before and after cardiopulmonary bypass. Aortic valve morphology, aortic root diameter, pulmonary valve morphology, pulmonary annulus diameter and mitral valve morphology were assessed by two-dimensional imaging. ⋯ Post-operative transoesophageal echocardiography showed a competent aortic valve in all but four of the remaining 239 patients. Intraoperative transoesophageal echocardiography is easy to learn and provides the surgeon additional information necessary to decide a particular procedure. In addition, intraoperative transoesophageal echocardiography provides accurate assessment of the results of surgery on the table.

Profound hypothermic circulatory arrest in management of aortic aneurysms.
A total of 15 patients having aneurysms of aorta were operated from June 1997 to December 1998 using deep hypothermic circulatory arrest as a modality of brain protection. There were 12 males and 3 females. The age ranged from 19 years to 74 years and the mean age was 44.9 years. ⋯ There was one instance of left hemiparesis secondary to an infarct in right frontoparietal region. To conclude, hypothermic circulatory arrest could provide an adequate brain protection for aortic aneurysm surgery. Retrograde cerebral perfusion could be an adjuvant when the anticipated time of hypothermic circulatory arrest is likely to exceed 45 minutes.
