Percutaneous Carillon Mitral Contour System Deployment Followed by CRT-D Implantation: First Case Report from Oman

Mitral valve regurgitation (MR) is a common problem in patients with cardiac issues especially those with dilated cardiomyopathy (DCM) due to mitral annular dilatation and malcoaptation of the mitral valve leaflets. Although DCM is associated with high mortality rates, there has been no global agreement about the best method of treatment. Treatment of MR in such cases can be done by surgery, which has many limitations due to high-risk concerns. MR may also be managed by other alternatives such as mitral-clip and transcoronary venous mitral annuloplasty using the Carillon® Mitral Contour System®. Combined therapy with a cardiac resynchronization therapy defibrillator (CRT-D) and mitral contour can be used in such cases with valuable improvement in general condition in many patients. In our case, we used the Carillon Mitral Contour System for treatment of severe MR in a 64-year-old patient with severely impaired systolic function after implantation of a CRT-D.
