Patients with bicuspid aortic valve are often complicated with aortic dilatation. If the aortic valve is of good quality, aortic root replacement with aortic valve preservation is feasible. A 35-year-old male patient with bicuspid aortic regurgitation complicated with ascending aortic aneurysm underwent Remodeling+Ring (modified Yacoub) operation. Echocardiography showed that there was no aortic regurgitation on the 3rd day after operation, and the patient was discharged satisfactorily on the 6th day after operation. Remodeling+Ring surgery ensures the physiological movement of the aortic valve, solves the enlarged annulus, avoids the problems caused by valve replacement, and significantly improves the quality of life of patients, which is worth popularizing.

Objective To evaluate the clinical effect of minimally invasive aortic valve replacement with Perceval sutureless aortic bioprosthesis in upper ministernotomy or right anterior thoracotomy. Methods From March to November 2022, the patients with simple aortic valve disease were enrolled in the Department of Cardiovascular Surgery of West China Hospital, Sichuan University. After preoperative evaluation, Perceval sutureless bioprosthesis was successfully used to perform aortic valve replacement through the upper ministernotomy or right anterior thoracotomy. The perioperative clinical data and ultrasonic measurement data of all patients were recorded. Results A total of 5 patients with simple aortic valve disease were included, including 3 females and 2 males, with a mean age of 71.2 years. Perceval sutureless bioprosthesis was successfully implanted in 5 patients, with a success rate of 100%. There were 3 patients receiving upper ministernotomy and 2 patients receiving right anterior thoracotomy. Two patients underwent ascending aortic plasty at the same time. The mean cardiopulmonary bypass time was 61.0 min, and aortic cross-clamping time was 32.2 min. All patients were discharged successfully without perivalvular leakage, atrioventricular block or stroke. Conclusion The implantation method of Perceval sutureless bioprosthesis is simple, which can effectively reduce the perioperative risk by shortening the overall operation time, cardiopulmonary bypass time and aortic cross-clamping time. At the same time, its clinical application has promoted the development and popularization of minimally invasive aortic valve replacement, which together with Perceval sutureless bioprosthesis effectively combinates surgical effect and minimally invasive treatment, and has a good clinical application prospect because of its reliable safety and effectiveness.

Objective To evaluate the clinical efficacy of two-stage retrograde hybrid repair for acute aortic dissection involving the aortic arch complicated with distal malperfusion syndrome. Methods From May 2019 to December 2022, the patients presented with acute aortic dissection involving the aortic arch complicated with distal malperfusion syndrome treated in the Department of Cardiovascular Surgery of West China Hospital, Sichuan University were enrolled. After preoperative evaluation, all patients underwent priority emergency interventional surgery to improve distal malperfusion, and then underwent two-stage hybrid surgery to repair proximal aortic lesions. The perioperative clinical and imaging data were retrospectively analyzed. Results Five patients were collected, including 4 males and 1 female, with a median age of 58 years. The main manifestations were lower limb ischemia and renal insufficiency in 3 patients, and poor intestinal perfusion in 2 patients. All patients were given priority to interventional surgery to implant graft stents or bare stents and necessary branch artery intervention, and then successfully performed two-stage hybrid surgery, including type Ⅰhybrid surgery for 2 patients, type Ⅱ hybrid surgery for 1 patient and type Ⅲ hybrid surgery for the other 2 patients, with a success rate of 100.0%. All patients were discharged successfully, and the function of the organs with poor perfusion returned to normal. Only 1 patient recovered to grade 4 muscle strength of the diseased lower limbs upon discharge. No adverse events such as amputation, exploratory laparotomy and intestinal resection or long-term hemodialysis occurred. Conclusion The application of two-stage retrograde hybrid repair in the surgical treatment of acute aortic dissection involving the aortic arch complicated with distal malperfusion syndrome is safe and effective, and is helpful to improve the perioperative survival rate, and clinical outcomes of such patients.
