[PMID: 37839658 DOI: 10.1016/j.jtcvs.2023.10.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 09/09/2023] [Accepted: 10/01/2023] [Indexed: 10/17/2023]
Abstract
OBJECTIVE Transatrial transcatheter mitral valve replacement reduces complexity during mitral valve replacements involving high-risk patients with mitral annular calcification. This study examines trends in transatrial transcatheter mitral valve replacement use and outcomes. METHODS Patients in the Society of Thoracic Surgeons database from 2014 to 2021 with mitral annular calcification undergoing transatrial transcatheter mitral valve replacement were included. Exclusion criteria were hypertrophic cardiomyopathy, congenital mitral valve disease, ventricular assist device placement, or prior mitral valve surgery. Primary outcomes were operative mortality and major adverse cardiac events compared between the Early (2014-2017, N = 71) and Recent (2018-2021, N = 151) eras. Parsimonious multivariable regression assessed select possible confounders for trends in major adverse cardiac events. RESULTS Overall, 222 transatrial transcatheter mitral valve replacements at 104 hospitals were identified. Annual volume increased from 6 in 2014 to 43 in 2021. Median hospital volume was 1, maximum hospital volume was 17, and 10 or more replacements were performed at 4 hospitals. Mortality and major adverse cardiac events occurred in 10.4% and 22.5% of patients, respectively. Compared with the Early era patients, Recent era patients were more often elective (79.5% vs 64.8%) and were approached via sternotomy (90.1% vs 80.3%, all P < .05). Despite similar predicted risk of mortality (9.6% ± 11.1% vs 11.0% ± 6.0%; P = .61), Recent patients had reduced mortality (3.3% vs 25.4%, P < .001) and major adverse cardiac events (18.5% vs 31.0%; P = .057). On univariate and multivariable analyses, the Recent surgical era was significantly associated with lower mortality (0.10 [0.04-0.29]; P < .001) and lower major adverse cardiac events (0.48 [0.25-0.94]; P = .032), respectively. There were no preoperative characteristics that were significant confounders for the difference in major adverse cardiac events. CONCLUSIONS Mortality and major adverse cardiac events after transatrial transcatheter mitral valve replacement have decreased significantly in the contemporary era independent of changes in major patient and operative characteristics. Transatrial transcatheter mitral valve replacement will have a future role in patients with mitral annular calcification.

Hybrid Surgery for Severe Mitral Valve Calcification: Limitations and Caveats for an Open Transcatheter Approach. MEDICINA (KAUNAS, LITHUANIA) 2022; 58:medicina58010093. [PMID: 35056401 PMCID: PMC8777627 DOI: 10.3390/medicina58010093] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/18/2021] [Revised: 12/28/2021] [Accepted: 12/31/2021] [Indexed: 11/24/2022]
Abstract
Background and Objectives: Mitral stenosis with extensive mitral annular calcification (MAC) remains surgically challenging in respect to clinical outcome. Prolonged surgery time with imminent ventricular rupture and systolic anterior motion can be considered as a complex of causal factors. The aim of our alternative hybrid approach was to reduce the risk of annual rupture and paravalvular leaks and to avoid obstruction of the outflow tract. A review of the current literature was also carried out. Materials and Methods: Six female patients (mean age 76 ± 9 years) with severe mitral valve stenosis and severely calcified annulus underwent an open implantation of an Edwards Sapien 3 prosthesis on cardiopulmonary bypass. Our hybrid approach involved resection of the anterior mitral leaflet, placement of anchor sutures and the deployment of a balloon expanded prosthesis under visual control. Concomitant procedures were carried out in three patients. Results: The mean duration of cross-clamping was 95 ± 31 min and cardiopulmonary bypass was 137 ± 60 min. The perioperative TEE showed in three patients an inconspicuous, heart valve-typical gradient on all implanted prostheses and a clinically irrelevant paravalvular leakage occurred in the anterior annulus. In the left ventricular outflow tract, mild to moderately elevated gradients were recorded. No adverse cerebrovascular events and pacemaker implantations were observed. All but one patient survived to discharge. Survival at one year was 83.3%. Conclusions: This “off label” implantation of the Edwards Sapien 3 prosthesis may be considered as a suitable bail-out approach for patients at high-risk for mitral valve surgery or deemed inoperable due to extensive MAC.

Surgical implantation of balloon-expandable heart valves for the treatment of mitral annular calcification. J Thorac Cardiovasc Surg 2021:S0022-5223(21)01245-9. [PMID: 34635317 DOI: 10.1016/j.jtcvs.2021.08.047] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/10/2021] [Revised: 08/12/2021] [Accepted: 08/13/2021] [Indexed: 11/22/2022]
Abstract
OBJECTIVES The treatment of mitral valve disease in the presence of mitral annular calcification (MAC) is associated with an increased risk of cardiovascular and all-cause mortality. Various surgical and transcatheter techniques for the treatment of mitral disease with severe MAC have been described. However, these procedures are associated with high risk of operative morbidity and mortality. We describe our experience with open surgical implantation of a balloon-expandable valve (BEV) in patients with severe MAC as an alternative approach. METHODS BEV implantation was performed with direct vision through the left atrium via a median sternotomy or minimally invasive approach. The midportion of the anterior leaflet is excised, and a ventricular septal myectomy performed if there is high risk for left ventricular outflow tract obstruction. The primary outcome was technical success according to the Mitral Valve Academic Research Consortium criteria; secondary outcomes were 30-day and 1-year mortality. RESULTS From October 2015 through October 2020, 51 patients at 2 institutions underwent BEV-in-MAC (mean age, 73.9 ± 8.8 years; 60.8% [31/51] were female; mean Society of Thoracic Surgeons predicted risk of mortality: 6.8% ± 4.8%). Technical success was 94.1% (48/51). Thirty-day and 1-year mortality were 13.7% (7/51) and 33.3% (15/45), and for stroke 3.9% (2/51) and 4.4% (2/45), respectively. CONCLUSIONS Surgical implantation of a BEV in the mitral position offers a treatment option for patients with mitral valve disease complicated by severe MAC who are at increased risk for conventional surgical approaches and at risk for left ventricular outflow tract obstruction with transcatheter approaches.

Abstract
Mitral annular calcification (MAC) is a degenerative process of the fibrous structure of the mitral valve. Surgical mitral valve replacement in the presence of MAC is technically challenging because of a high calcium burden and is associated with prohibitive operative mortality. There is no standard management strategy for patients with severe aortic stenosis and severe mitral valve disease with MAC. We report a case series of 3 patients who underwent concomitant surgical, transatrial implantation of a transcatheter heart valve in the mitral position and transcatheter aortic valve replacement.

Abstract
BACKGROUND Mitral annular calcification (MAC) occurs represents a challenge to surgeons during mitral valve (MV) surgery with increased perioperative risk. CASE PRESENTATION We describe a challenging case of an elderly female patient with multiple comorbidities who presented with symptoms and signs of heart failure with a previous history of mechanical aortic valve replacement 15 years prior to presentation. Echocardiogram showed severe mitral stenosis and regurgitation with severe calcification of the mitral annulus. Given her high-risk profile and unavailability of suitable percutaneous therapeutic options we decided to replace her mitral valve with Sapien 3 valve under direct exposure. The case describes the technical details for the valve implantation and demonstrates the viability of this option in high risk surgical patients without the need for adjunct techniques like predilatation, additional supporting sutures or patches with a review of the literature on open surgical implantation of Sapien 3 valve. CONCLUSION Direct open surgical implantation of Sapien 3 valve can be implanted safely in patients with severe MAC, without predilatation and without the use of other adjunctive techniques like fixation sutures or patches.

Abstract
A 79-year-old woman with severe mitral annular calcification was scheduled for mitral valve replacement. A SAPIEN 3 valve was implanted in mitral position using an open surgical approach. Immediately after cardiopulmonary bypass, bleeding from an unidentified source was encountered. Cardiopulmonary bypass was emergently resumed and a laceration of the left ventricular apex due to the valve delivery system was detected. Risk factors specific to the open surgical approach include a decompressed ventricle, decreased annulus to apical distance, and the absence of continuous fluoroscopic and echocardiographic imaging. These create a clinical scenario where risk of ventricular perforation is increased compared with traditional intravascular transcatheter valve delivery.
