Partial aortic root remodeling for chronic aortic dissection with coronary intimal tear
This report presents a case of a 69-year-old man incidentally diagnosed with aortic dissection during routine checkup. He had a history of percutaneous coronary intervention from the left main trunk to the left anterior descending artery and left circumflex artery. Computed tomography revealed a chronic type A aortic dissection with an aneurysmal aortic root. The false lumen of the Valsalva sinus originated from the left anterior descending artery and expanded largely to the non-coronary Valsalva sinus. We performed partial aortic root remodeling, resecting the dissected non-coronary Valsalva sinus. The postoperative course was uneventful. Partial aortic root remodeling was effective, but its use might be controversial for chronic aortic dissection without resection of the primary entry of the left anterior descending artery. Moreover, close follow-up is required.
