Abstract
OBJECTIVE Implantation of a transcatheter valve-in-mitral annular calcification (ViMAC) has emerged as an alternative to traditional surgical mitral valve (MV) replacement. Previous studies evaluating ViMAC aggregated transseptal, transapical, and transatrial forms of the procedure, leaving uncertainty about each technique's advantages and disadvantages. Thus, we sought to evaluate clinical outcomes specifically for transatrial ViMAC from the largest multicenter registry to-date. METHODS Patients with symptomatic MV dysfunction and severe MAC who underwent ViMAC were enrolled from 12 centers across the United States and Europe. Clinical characteristics, procedural details, and clinical outcomes were abstracted from the electronic record. The primary end point was all-cause mortality. RESULTS We analyzed 126 patients who underwent ViMAC (median age 76 years [interquartile range {IQR}, 70-82 years], 28.6% female, median Society of Thoracic Surgeons score 6.8% [IQR, 4.0-11.4], and median follow-up 89 days [IQR, 16-383.5]). Sixty-one (48.4%) had isolated mitral stenosis, 25 (19.8%) had isolated mitral regurgitation (MR), and 40 (31.7%) had mixed MV disease. Technical success was achieved in 119 (94.4%) patients. Thirty (23.8%) patients underwent concurrent septal myectomy, and 8 (6.3%) patients experienced left ventricular outflow tract obstruction (7/8 did not undergo myectomy). Five (4.2%) patients of 118 with postprocedure echocardiograms had greater than mild paravalvular leak. Thirty-day and 1-year all-cause mortality occurred in 16 and 33 patients, respectively. In multivariable models, moderate or greater MR at baseline was associated with increased risk of 1-year mortality (hazard ratio, 2.31; 95% confidence interval, 1.07-4.99, P = .03). CONCLUSIONS Transatrial ViMAC is safe and feasible in this selected, male-predominant cohort. Patients with significant MR may derive less benefit from ViMAC than patients with mitral stenosis only.

JTCVS Tech 2023; 22:1-12. [PMID: 38152201 PMCID: PMC10750984 DOI: 10.1016/j.xjtc.2023.10.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2023] [Revised: 09/11/2023] [Accepted: 10/04/2023] [Indexed: 12/29/2023] Open
Abstract
Objectives Mitral annular calcification remains a formidable lesion in cardiac surgery with significant perioperative morbidity and mortality, particularly when en bloc annular decalcification is implemented. Respect strategies and hybrid approaches have provided safe alternatives. We report the short-term results of our institution's experience with mitral valve replacement in patients with extensive annular calcification. Methods This is a retrospective review of 72 consecutive patients with extensive annular calcification who underwent open surgical mitral valve replacement from January 1, 2013, to September 31, 2022. Degree of annular calcification was graded as partial, horseshoe, or circumferential. We excluded patients with calcification involving less than one-third of the annulus and patients with rheumatic heart disease. Results Mean patient age was 71.6 ± 10.9 years, and 50 (69.4%) were female. There were 51 patients (70.8%) with New York Heart Association class 3 or greater and 47 patients (65.3%) with pulmonary hypertension. There were 41 patients (56.9%) with partial, 12 patients (16.7%) with horseshoe, and 19 patients (26.4%) with circumferential calcification. Fifty-six patients (77.8%) underwent conventional valve replacement. Sixteen patients underwent a hybrid procedure using balloon-expandable devices. Concomitant procedures were performed in 61 patients (84.7%). In-hospital mortality and 1-year survival were 3.57% and 82.8% in the standard valve replacement cohort and 25.0% and 54.7% in the hybrid cohort, respectively. Conclusions Conventional mitral valve replacement using respect strategies is safe and associated with good outcomes in patients with extensive annular calcification. Hybrid approaches using novel devices should remain as a bailout in select patients because of higher perioperative risks and poor short-term outcomes.

Abstract
OBJECTIVES The objectives of this study were to examine operative and long-term results of combined aortic and mitral valve replacement when reconstruction of the fibrous skeleton of the heart is needed because of calcification, abscess, previous operations, or patient-prosthesis mismatch. METHODS From 1985 to 2020, 182 consecutive patients underwent combined aortic and mitral valve replacement with reconstruction of the intervalvular fibrous skeleton in all cases and also the posterior mitral annulus in 63 patients. Bovine pericardium or Dacron grafts were used for the reconstructions. Median follow-up was 7.5 (interquartile range, 2.1-12.6) years and 98% complete. RESULTS Patient mean age was 62 years; 69% had 1 or more previous valve operations, and 92% were functional class III or IV. The indications for reconstruction were extensive calcification of the fibrous skeleton in 34%, abscess in 13%, tissue damage secondary to previous operations in 39%, and patient-prosthesis mismatch of the mitral valve in 13%. Bovine pericardium was used in two-thirds of cases and Dacron grafts in one-third. Operative mortality was 13.2% and postoperative complications were common. Survival at 1, 10, and 20 years was 81.8%, 51.1%, and 23.7%, respectively. Fourteen patients required reoperation and 3 transcatheter interventions. The cumulative probability of reinterventions at 1, 10, and 20 years were 3.3%, 5.8%, and 9.1%, respectively. Most patients experienced symptomatic improvement postoperatively. CONCLUSIONS Reconstructions of the fibrous skeleton of the heart are associated with high operative mortality but the long-term results are satisfactory because most patients would not have survived without surgical intervention.
