Commando procedure, the surgical replacement of mitral and aortic valves combined with reconstruction fibrosa fibrous body, is a technical challenge in patients small annuli. In this study, we evaluated safety early outcomes "Chimney" modality annuli, after prior valve surgery, using self-assembled valved conduit.From April 2021 to 2022, 30 consecutive cases conduit other cardiac procedures, were fully performed for re-operative roots. Data obtained through medical record review, at Asian Heart Hospital Wuhan, China.The patient's mean age was 52.7 ± 13.53 years, 93.3% females. All had previous heart 90% which double (DVR). death occurred 3.3% (n = 1) patients, due malignant arrhythmias multiorgan failure. Postoperative echocardiogram exams showed that sizes prostheses 24.23 1.60 mm 28.33 1.21 mm, respectively. intact intervalvular (IVF) repair no patient any aberration left chamber communication. With exception one postoperative sick sinus syndrome re-sternotomy bleeding, there significant complications, such as mortality, renal failure requiring ongoing dialysis, or mediastinitis. Echocardiography sixth month gradients 16.26 6.44 mmHg 11.24 4.90 mmHg, respectively.In comparison standard operation, procedure proved be feasible therapeutic option operations. This approach enables enlargement annuli implantation necessary prosthesis.
