Aortic Valve Replacement by Subannular Endomyocardial Implantation of Valve Prosthesis in Behçet’s Disease

The novel anastomosis technique, “subannular endomyocardial implantation of valve prosthesis (SEIV),” focuses on excluding aortic annular tissue from suture line to avoid vascular inflammation in Behçet’s disease (BD). We aimed to validate that SEIV could prevent prosthetic valve detachment (PVD) after aortic valve replacement (AVR) in BD patients and retrospectively analyzed the medical records of five BD patients who underwent AVR. There was no operative death. Two complete atrioventricular blocks occurred; in one of them, a permanent pacemaker (PPM) was inserted before discharge. The other one was discharged without a PPM; however, he died suddenly 32 days postoperatively. The median follow-up period was 3.3 years. There was a case of PVD with newly developed Valsalva sinus aneurysm requiring the Bentall operation at 3.6 years postoperatively. In conclusion, SEIV might prevent PVD in BD patients who underwent AVR. However, aortic root pathology related to BD activity and resulting PVD may occur later.
