Totally Endoscopic Aortic Valve Replacement and Transaortic Mitral Valve Repair

The authors present the case of a 77-year-old woman in NYHA class 3, due to severe AS and severe secondary MR. The operation was performed with the authors’ totally endoscopic technique, which has been previously published on CTSNet (1-4). A 3D 30-degrees Karl Storz endoscope was used. Under stereoscopic vision, the mitral valve was approached through the aortotomy after the excision of the calcific aortic valve. A self-expanding metal net (Fehling) was deployed in the aortic annulus in order to facilitate the exposure of the mitral valve leaflets and subvalvar apparatus. A horizontal mattress Teflon buttressed CV4 Gore-Tex suture was used to capture the middle of the P2 and A2 segments of the mitral valve. Then, the Trifecta (Abbott) aortic prostheses was inserted over 12 Ethibond sutures and secured using the Cor-Knot device.

Postoperative TOE confirmed a well-functioning aortic prosthesis and a satisfactory mitral valve repair with less than 1+ MR, a peak mitral gradient of 5.9 mmHg and a valve area of 3.2 cm2. Cross-clamp and CPB times were 91 and 123 minutes respectively.

The authors believe that this technique is indicated in cases of severe secondary mitral regurgitation due to dilated cardiomyopathy secondary to aortic valve disease.
