Complications Following Percutaneous Mitral Valve Edge-to-Edge Repair Using MitraClip.

ABSTRACT: Percutaneous mitral valve edge-to-edge repair with MitraClip (Abbott, Abbott Park, Illinois) has emerged as an effective and safe treatment for symptomatic mitral regurgitation in suitable patients. The safety of the MitraClip procedure is well established, and the rate of major complications is 4.35%. We present 4 cases of mitral regurgitation in patients who had complications following the MitraClip procedure. (Level of Difficulty: Intermediate.).

Project description:ObjectiveIn the current study, we present our mid-term experience with modified edge-to-edge repair technique through a transventricular and transaortic route in patients requiring left ventricular remodeling or aortic root/valve surgery.MethodsFrom December 2006 through April 2015, 49 high-risk patients (median age: 69 years; median European System for Cardiac Operative Risk Evaluation II: 11.4 [6.54-14.9]) underwent transventricular (N = 7; 14%) or transaortic (N = 42; 86%) edge-to-edge mitral valve repair. The Alfieri stitch technique was modified by MitraClip type overcorrection and solid buttressing behind the posterior leaflet. Indication was grade 2+ functional mitral valve incompetence and dilated or impaired left ventricle (N = 25; 52%), or grade 3+ (N = 22; 45%) and grade 4+ functional mitral valve regurgitation (N = 2; 4%). Surgical procedure included aortic root surgery in 65%, aortic valve replacement with surgical revascularization in 18%, and Dor-plasty with surgical revascularization in 14%.ResultsIntraoperative mortality and early neurologic complications were absent in our series. Ninety-day mortality was 12.2% (N = 6). Median clinical and echocardiographic follow-up-time was 50.7 (21.5-44.1) and 39.2 (33.7-44.1) months, respectively. Median postoperative transvalvular gradient was low (2.72 [1.91-4.22] mm Hg) and did not increase during follow-up (P = .268), although peak gradient rose slightly from 7.41 to 8.12 mm Hg (P = .071). The actuarial reoperation free rate at the index valve was 96.8%.ConclusionsTransventricular or transaortic Alfieri mitral repair mimicking mitral clip overcorrection represents a quick and safe technique in the setting of high-risk patients undergoing left ventricular remodeling or aortic root/valve surgery and can be performed with low risk of creating mitral stenosis at midterm. The technique is straightforward, with reliable identification of the center of the valve leaflets being the limitation.

Project description:BackgroundTranscatheter edge-to-edge repair (TEER) of the mitral valve (MV) can be performed using the PASCAL or MitraClip devices. Few studies offer a head-to-head outcome comparison of these two devices.Material and methodsPubMed, EMBASE, Cochrane Library, Clinicaltrials.gov and WHO's International Clinical Trials Registry Platform, from 1 January 2000 until 1 March 2023, were searched. Study protocol details were registered in the International Prospective Register of Systematic Reviews (PROSPERO ID: CRD42023405400). Randomized Controlled Trials and observational studies reporting head-to-head clinical comparison of PASCAL and MitraClip devices were eligible for selection. Patients with severe functional or degenerative mitral regurgitation (MR) who had undergone TEER of the MV with either PASCAL or MitraClip devices were included in the meta-analysis. Data from six studies (five observational and one randomized clinical trial) were extracted and analyzed. The main outcomes were a reduction in MR to 2+ or less, improvement of New York Heart Association (NYHA) and 30-day all-cause mortality. Peri-procedural mortality, success rate and adverse events were also compared.ResultsData from 785 and 796 patients that underwent TEER using PASCAL and MitraClip, respectively, were analyzed. Thirty-day all-cause mortality (Risk ratio [RR] = 1.51, 95% CI 0.79-2.89), MR reduction to maximum 2+ (RR = 1.00, 95% CI 0.98-1.02) and NYHA improvement (RR = 0.98, 95% CI 0.84-1.15) were similar in both device groups. Both devices had high and similar success rates (96.9% and 96.7% for the PASCAL and MitraClip group, respectively, p value = 0.91). MR reduction to 1+ or less at discharge was similar in both device groups (RR = 1.06, 95% CI 0.95-1.19). Composite peri-procedural and in-hospital mortality was 0.64% and 1.66% in the PASCAL and MitraClip groups, respectively (p value = 0.094). Rates of peri-procedural cerebrovascular accidents were 0.26% in PASCAL and 1.01% in MitraClip (p value = 0.108).ConclusionsBoth PASCAL and MitraClip devices have high success and low complication rates for TEER of the MV. PASCAL was not inferior to MitraClip in reducing the MR level at discharge.
