Hemi-root replacement with diagonal resection of the aortic root preserving the ostium of the left coronary artery and sacrificing the right coronary artery for an infected pseudoaneurysm: a case report.

Either the Bentall-De Bono operation or the valve-sparing aortic root replacement is commonly chosen for aortic root management. However, if the preoperative condition is poor, a simpler technique is preferred; therefore, we performed hemi-root replacement with diagonal resection of the aortic root preserving the left coronary sinus of Valsalva. Because reimplantation of the left coronary artery is not required, this technique may shorten operative time and reduce coronary malperfusion, a condition characterized by reduced transit flow time and reduced cardiac contractility.
