Feasibility of inpatient cardiac rehabilitation after percutaneous mitral valve reconstruction using clipping procedures: a retrospective analysis

Background: To date, no studies on the feasibility or outcomes of cardiac rehabilitation (CR) after percutaneous mitral valve reconstruction using clipping procedures have been published. The aim of this study was to report on our first experiences with this special target group. Methods: Monocentric retrospective analysis of 27 patients (72 ± 12 years old, 52% female) who underwent multimodal inpatient CR in the first 2 month after MitraClip™ implantation. A six-minute-walking-test, a handgrip-strengthtest and the Berg-Balance-Scale was conducted at the beginning and end of CR. Echocardiography was performed to rule out device-related complications. Results: Adapted inpatient CR started 16 ± 13 days after clipping intervention and lasted 22 ± 4 days. In 4 patients (15%) CR had to be interrupted or aborted prematurely due to cardiac decompensations. All other patients (85%) completed CR period without complications. Six-minute-walking-distance improved from 272 ± 97 to 304 ± 111 m (p < .05) and dependence on rollator walker or walking aids was significantly reduced (p < .05). Results of handgripstrength- test and Berg-Balance-Scale increased (p < .05). Overall, social-medical and psychological consultations were well received by the patients and no device-related complications occurred during rehabilitation treatments. Conclusions: The results indicate that an adapted inpatient CR in selected patients after MitraClip™ implantation is feasible. Patients benefited from treatments both at functional and social-medical level and no device-related complications occurred. Larger controlled studies are needed.
