To the Editor
We thank Drs Silberman, Fink, and Bitran for summarizing their experience with aortic valve replacement using deep hypothermic circulatory arrest. Their experience is similar to ours [1], and we congratulate them on excellent results in this difficult group of patients. We would suggest, however, that preoperative computed tomography of the chest is not necessary, provided epiaortic echocardiography is available. The epiaortic echo probe can usually identify areas for safe cannulation, clamping, and aortotomy. It can also exclude areas that are not safe for manipulation, as we documented in our report.
