Intensive care and anesthesia management for HARPOON beating heart mitral valve repair.

ABSTRACT: Patients with severe mitral valve regurgitation secondary to degenerative disease are known to benefit from mitral valve repair surgery. Novel techniques for achieving mitral valve repair on the beating heart have been developed and are being introduced into clinical practice. The HARPOON Beating Heart Mitral Valve Repair System (MVRS) in recent studies has demonstrated efficacy and safety for the repair of degenerative mitral valve disease on the beating heart. The device uses transoesophageal echocardiographic guidance to implant artificial expanded polytetrafluoroethylene (ePTFE) cords on prolapsed mitral valve leaflets in the beating heart. It requires general anaesthesia and there are specific intensive care and anaesthesia considerations for the safe management of these cases. This article describes the general principles of intensive care and anaesthesia management employed for the initial patients treated with the HARPOON Beating Heart MVRS, the outcomes for these patients, and the potential challenges for the future management of these cases.

Project description:BACKGROUND:In the COAPT (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation) trial, transcatheter mitral valve repair (TMVr) led to reduced heart failure (HF) hospitalizations and improved survival in patients with symptomatic HF and 3+ to 4+ secondary mitral regurgitation (MR) on maximally-tolerated medical therapy. Given the advanced age and comorbidities of these patients, improvement in health status is also an important treatment goal. OBJECTIVES:The purpose of this study was to understand the health status outcomes of patients with HF and 3+ to 4+ secondary MR treated with TMVr versus standard care. METHODS:The COAPT trial randomized patients with HF and 3+ to 4+ secondary MR to TMVr (n = 302) or standard care (n = 312). Health status was assessed at baseline and at 1, 6, 12, and 24 months with the Kansas City Cardiomyopathy Questionnaire (KCCQ) and the SF-36 health status survey. The primary health status endpoint was the KCCQ overall summary score (KCCQ-OS; range 0 to 100; higher = better; minimum clinically important difference = 5 points). RESULTS:At baseline, patients had substantially impaired health status (mean KCCQ-OS 52.4 ± 23.0). While health status was unchanged over time in the standard care arm, patients randomized to TMVr demonstrated substantial improvement in the KCCQ-OS at 1 month (mean between-group difference 15.9 points; 95% confidence interval [CI]: 12.3 to 19.5 points), with only slight attenuation of this benefit through 24 months (mean between-group difference 12.8 points; 95% CI: 7.5 to 18.2 points). At 24 months, 36.4% of TMVr patients were alive with a moderately large (≥10-point) improvement versus 16.6% of standard care patients (p < 0.001), for a number needed to treat of 5.1 patients (95% CI: 3.6 to 8.7 patients). TMVr patients also reported better generic health status at each timepoint (24-month mean difference in SF-36 summary scores: physical 3.6 points; 95% CI: 1.4 to 5.8 points; mental 3.6 points; 95% CI: 0.8 to 6.4 points). CONCLUSIONS:Among patients with symptomatic HF and 3+ to 4+ secondary MR receiving maximally-tolerated medical therapy, edge-to-edge TMVr resulted in substantial early and sustained health status improvement compared with medical therapy alone.
