Dr Ralph Damiano
(St Louis, Mo). The effect of surgical procedures for AF on LA function remains poorly defined and controversial. Your group has used sophisticated imaging to begin to look at this important issue. We have also been interested in the functional changes in the left atrium after surgical ablation and have used similar technology, both clinically and experimentally, to help us address these important questions.
It can be hard to get these patients to return for follow-up, and I commend you on your persistence in what is a large series of follow-up MRI scans.
All of your patients were in permanent or persistent AF preoperatively. We have had tremendous problems obtaining MRI scans in these patients because of the difficulty in gating the irregular rhythm. How did you overcome these challenges and are you sure you did not miss part of the cardiac cycle in these patients?
Dr Marui. "Thank you, Dr. Damiano, for your kind comments and questions. We recognize your contribution to this field of AF surgery" Your first question is an important one, because gating of MRI in patients with . . . [Full Text of this Article]
