Transcatheter Aortic Valve Replacement as a bridge to minimally invasive endoscopic mitral valve surgery in Elderly Patients in the era of ERAS and Fast Track TAVI concepts.

In this bicentric study, we report the outcomes of combined transcatheter aortic valve replacement combined with minimally invasive mitral valve surgery. We included a cohort of six patients (79.6 ± 3.2 years, 83% women) with high-risk profiles and deemed to be non-operable with combined mitral and aortic valvular disease. All patients had unsuitable anatomies for transcatheter mitral valve edge-to-edge repair (TEER). Moreover, most of the patients (5/6) suffered a combined aortic valve lesion, which complicates the efficiency of cardioplegia in the case of CBP through minimally invasive incisions. The first stage was implanting a TAVI valve to achieve aortic valve competency and hence facilitate the infusion of cardioplegia after clamping the aorta during endoscopic mitral valve surgery. After one week, we performed the minimally invasive mitral valve repair. Most patients (n = 5; 83%) underwent successful endoscopic mitral valve repair. Intraoperatively, the mean ischemic time was 42 min, and the total bypass time was 72 min. Postoperatively, the mean intubation time was 0 h. Postoperative complications included reoperation for bleeding in one patient (16.7%) and a new heart block requiring pacemaker implantation in one patient (16.7%). There was neither in-hospital mortality nor 1-year mortality.

Feasibility and Efficacy of Transcatheter Tricuspid Valve Repair in Patients with Cardiac Implanted Electrical Devices and Trans-Tricuspid Leads.

BACKGROUND: Transcatheter tricuspid valve repair using the edge-to-edge-technique (TEER) has emerged as an alternative therapy in patients with severe tricuspid regurgitation (TR) and high surgical risk. This study aimed to evaluate the feasibility and efficacy of tricuspid valve TEER in patients with cardiac implanted electric devices (CIEDs). METHODS: All patients who underwent tricuspid valve TEER at our center were retrospectively included. Patients were classified according to the presence of CIEDs. Procedure success was defined as implantation of at least one clip and the reduction of TR of at least one grade. Procedure success and intrahospital outcome were compared between the two groups. RESULTS: One-hundred and six consecutive patients underwent tricuspid TEER (age 80.1 ± 6.4 years, male = 42; 39.6%). Among them, 25 patients (23.6%, age 80.6 ± 7.3 years, male = 14; 56%) had CIEDs. Patients with CIEDs had a significantly lower left ventricular ejection fraction (LV-EF) compared to those without CIEDs (47.2 ± 15% vs. 56.2 ± 8.2%, p = 0.004, respectively). Moreover, arterial hypertension was more common in patients with CIEDs (96% vs. 79%, p = 0.048). The success of the procedure did not differ between the non-CIED vs. CIED group (93.8% vs. 92%, p = 0.748). Furthermore, the number and position of implanted clips, the duration of the procedure, the post-procedural pressure gradient across the tricuspid valve, and post-procedural TR severity were comparable between both groups. CONCLUSION: Tricuspid valve TEER is feasible and efficient in patients with CIEDs. The success of the procedure, as well as the intrahospital outcome were comparable between patients with and without CIEDs.
