The authors present a video describing the surgical management of a 38-year-old female patient with a 5.1 cm ascending aortic aneurysm, aortic root dilation, and paroxysmal atrial fibrillation that required operative treatment. Both valve-sparing aortic root replacement and left atrial and pulmonary vein ablation techniques are described step by step, highlighting potentially challenging aspects and providing details of the authors’ respective approaches.
The first portion of the video focuses on the preoperative imaging evaluation, surgical setup, optimal positioning of the ablation clamp around the posterior aspect of the heart, and strategies for extending the ablation cycles.
This is followed by a detailed description of the aortic procedure, including the extent of aortic root tissue dissection, valve assessment and valve-sparing criteria, aortic root tissue excision, graft selection for appropriate root replacement, graft marking to facilitate even suture distribution, and aortic annular suture placement with particular attention to its potential interaction with the aortic valve leaflets.
Finally, the authors demonstrate valve reorientation with commissural resuspension, suture placement, and coronary button reimplantation. These technical aspects represent the key considerations for maximizing the likelihood of a favorable surgical outcome.
