AI Article Synopsis

  • * A total of 587 patients were analyzed, with no significant differences in primary outcomes such as death or re-hospitalization at 1 month and 1 year between those with and without AI.
  • * Results showed that two-thirds of patients with combined AI and MR experienced an improvement in AI severity post-procedure, suggesting that m-TEER can be an effective treatment option for high-risk patients dealing with both conditions.

Article Abstract

The presence of concomitant aortic insufficiency (AI) and mitral regurgitation (MR) is common and may further accelerate cardiac dysfunction. However, there exists no US regulatory-approved transcatheter device for the treatment of AI. The effectiveness of isolated transcatheter mitral therapy in this population is not well-understood; thus, we aimed to evaluate outcomes for patients with combined AI and MR compared with isolated MR who underwent mitral transcatheter edge-to-edge repair (m-TEER). Retrospective data were obtained from the Northwell m-TEER registry. A total of 587 patients who underwent m-TEER at 4 high-volume transcatheter aortic valve replacement/transcatheter edge-to-edge repair centers within the Northwell Health system were included. All patients had severe MR and were divided into 2 groups: group 1 with ≥3+ AI (AI+) and the group 2 with <3+ AI (AI-). Echocardiographic outcomes were evaluated at 1 month. Clinical outcomes were evaluated at 1 month and 1 year. The primary end point was death or rehospitalization at 1 year. A total of 587 patients were included in the study, with 92 in the AI+ group. Baseline characteristics were similar in both groups. Approximately 2/3 of patients in the AI+ group demonstrated an improvement in AI severity after isolated mitral therapy. There was no difference in the primary outcome at 1 month or 1 year. There was also no significant difference in New York Heart Association functional class at 1 month between the groups. In conclusion, patients who underwent m-TEER with combined MR and AI (AI+ group) fared well compared with those with isolated mitral valve dysfunction (AI- group), with no discernible differences in survival, New York Heart Association class, or rehospitalization rates at 1 month or 1 year. Hence, isolated m-TEER is a reasonable treatment approach in patients with a high surgical risk with combined AI and MR.

Purpose: To report the outcomes of the early feasibility study of transapical transcatheter mitral valve replacement (TMVR) with the SATURN System (InnovHeart, Milano, Italy) to treat patients with severe functional mitral regurgitation.

Description: Five high surgical risk patients underwent transapical transcatheter mitral valve replacement with the SATURN System at a single center. One-year follow-up is complete for all patients.

We report a case of a woman who underwent mitral ring and tricuspid annuloplasty. Two months later, she presented with acute heart failure secondary to severe aortic regurgitation, which was a complication of the cardiac surgery. Given the high surgical risk of reoperation in this the patient, she underwent transcatheter aortic valve implantation, with a good result.

Severe mitral annular calcification increases the risk associated with conventional mitral valve replacement. We report a case of surgical mitral valve replacement after migration of 3 transcatheter mitral valves in a patient with severe mitral annular calcification.

Objective: The concept of proportionate and disproportionate functional mitral regurgitation suggests that transcatheter edge-to-edge mitral repair may benefit patients with a smaller left ventricle relative to a higher regurgitant burden. The clinical relevance of proportionality remains unknown in mitral operations for ischemic mitral regurgitation. We aimed to characterize the association between mitral regurgitation proportionality and outcomes after mitral valve operations.

Background: Secondary mitral regurgitation (SMR) is a condition affecting the left ventricle (LV) rather than the mitral valve (MV). If the MV remains structurally unchanged, enlargement of the LV or impairment of the papillary muscles can occur. Several mechanical interventions are available to dictate the resolution of MR.
