Transapical transcatheter aortic valve replacement using Ken-Valve for severe aortic stenosis combined with severe aortic regurgitation: A case report / 中国胸心血管外科临床杂志

@#Transcatheter aortic valve replacement (TAVR) for severe aortic stenosis is growing rapidly. The use of new heart valves prosthesis has improved surgical safety and efficacy. This report described a 72-year-old male patient with severe aortic stenosis combined with severe aortic regurgitation, who was evaluated at moderate-high risk of surgery and received a transapical TAVR using the Ken-Valve heart valve. The transcatheter operation time was 8 min, and the blood loss was 50 mL. The tracheal intubation was removed immediately after the surgery. Transesophageal echocardiography on the 4th postoperative day showed that the aortic valve leaflets worked well, and there was no valve orifice and paravalvular leakage. The patient was discharged on the 5th day after the surgery without complications. Transapical TAVR using Ken-Valve was an easy surgical procedure for aortic valve disease, and had short operation time.

Early and mid-term outcomes of total thoracoscopic Box Lesion radiofrequency ablation in patients with atrial fibrillation / 中国胸心血管外科临床杂志

@#Objective    To evaluate the early and mid-term outcomes of total thoracoscopic Box Lesion radiofrequency ablation in patients with atrial fibrillation. Methods    The clinical data of 31 patients with atrial fibrillation who underwent total thoracoscopic Box Lesion radiofrequency ablation between November 2011 and March 2018 at the Department of Cardiac Surgery in our hospital were retrospectively analyzed, including 23 males and 8 females at an average age of 66.17±8.32 years. All patients did not have concomitant severe organic heart disease which required surgical intervention. Results    There were 20 patients with paroxysmal atrial fibrillation, 8 with persistent atrial fibrillation, and 3 with long-standing persistent atrial fibrillation. Twenty-nine patients got the 3-year follow-up, and 2 patients were lost to the follow-up 6 months after the surgery. The procedure was successfully performed in all patients, with an average operation time of 113.00±26.00 min. There was no perioperative death or related complication. All patients were restored to sinus rhythm immediately after surgery. Five patients got atrial fibrillation during postoperative hospitalization, which reverted to sinus rhythm after electrical cardioversion. The rate of sinus rhythm maintenance was 62.9%, 55.9% and 52.4%in postoperative 1, 2 and 3 years, respectively. No patient died during the period, and no procedure-related complication was observed. Conclusion    Total thoracoscopic Box Lesion radiofrequency ablation effectively shortens operation time, and reduces surgical trauma and procedure-related complications, meanwhile, ensures the surgical outcomes.
