Key result
Minimally invasive mitral valve replacement through intraluminal aortic clamping was successfully performed in a 50-year-old female with mitral valve obstruction after heart transplantation.
Case Report (n=1)
Minimally invasive mitral valve replacement using intraluminal aortic clamping is a feasible option for patients requiring redo surgery after heart transplantation, avoiding the risks of resternotomy.
Single-case success suggests potential alternative to resternotomy in post-transplant mitral reoperation; leaves open questions of safety and efficacy.
A 50-year-old female presented with progressive heart failure due to obstruction of the mitral valve after heart transplantation in 2008. Through the occlusion catheter (IntraClude Intra-Aortic Occlusion Device), aortic cross-clamping, antegrade cardioplegia, and aortic root venting were performed. Our case reports the first published study on minimally invasive mitral valve replacement for valve stenosis through intraluminal aortic clamping. The hazard of traumatic injuries can be reduced by avoiding resternotomy and circumventing adhesions between the aorta and the pulmonary artery after heart transplantation. Minimally invasive valve surgery is a safe and effective method with regard to short- and long-term results, especially in redo operations.
