Application of preset coronary artery orifice patch in Bentall surgery

Abstract

Abstract Background Bentall surgery is the main method for treating aortic root lesions, but traditional Bentall method is very difficult for patients with mild aortic sinus dilation to directly anastomose the coronary artery orifice with graft. Case presentation A 41-year-old man was admitted to hospital after severe chest pain. Computed tomography angiography(CTA)revealed a type A aortic dissection. Echocardiography showed moderate aortic valve regurgitation and an aortic sinus diameter of 38 mm( mm). The patient underwent emergency Bentall surgery (using a preset coronary artery orifice patch), total arch replacement, and implantation of a graft into the descending aorta. Follow-up echocardiography showed the patient cardiac function was good, and there was no residual leakage at the coronary artery orifice. Conclusions This method is an alternative to traditional Bentall surgery and is suitable for all aortic root lesions, especially those with mild aortic sinus dilation or concomitant aortic dissection.
