Secondary mitral regurgitation (SMR) is associated with increased mortality and heart failure hospitalizations. The management of heart failure patients with SMR is complex and requires a multidisciplinary Heart Team approach. Guideline-directed medical therapies remain fundamental, yet in a proportion of patients SMR persists. In the past decade, transcatheter edge-to-edge repair (TEER) has been shown to improve survival in patients with SMR who remain symptomatic despite medical therapy. Technical advancements across newer generations of devices, improved imaging, and greater operator expertise have collectively contributed to the increased safety and efficacy of this procedure over time. Various emerging transcatheter mitral valve repair and replacement devices are currently under investigation and may offer superior, complementary or synergistic treatment options in patients ineligible for TEER. This review provides a state-of-the-art overview regarding the diagnosis of SMR, and currently available transcatheter mitral valve interventions and describes a contemporary approach to the management of SMR., Competing Interests: Conflicts of interest statement Dr. Safi is a speaker for Medtronic and Abbott.

Background: Molecular testing with gene-expression profiling (GEP) and donor-derived cell-free DNA (dd-cfDNA) is increasingly used in the surveillance for acute cellular rejection (ACR) after heart transplant. However, the performance of dual testing over each test individually has not been established. Further, the impact of dual noninvasive surveillance on clinical decision-making has not been widely investigated., Methods: We evaluated 2,077 subjects from the Surveillance HeartCare Outcomes Registry registry who were enrolled between 2018 and 2021 and had verified biopsy data and were categorized as dual negative, GEP positive/dd-cfDNA negative, GEP negative/dd-cfDNA positive, or dual positive. The incidence of ACR and follow-up testing rates for each group were evaluated. Positive likelihood ratios (LRs+) were calculated, and biopsy rates over time were analyzed., Results: The incidence of ACR was 1.5% for dual negative, 1.9% for GEP positive/dd-cfDNA negative, 4.3% for GEP negative/dd-cfDNA positive, and 9.2% for dual-positive groups. Follow-up biopsies were performed after 8.8% for dual negative, 14.2% for GEP positive/dd-cfDNA negative, 22.8% for GEP negative/dd-cfDNA positive, and 35.4% for dual-positive results. The LR+ for ACR was 1.37, 2.91, and 3.90 for GEP positive, dd-cfDNA positive, and dual-positive testing, respectively. From 2018 to 2021, biopsies performed between 2 and 12-months post-transplant declined from 5.9 to 5.3 biopsies/patient, and second-year biopsy rates declined from 1.5 to 0.9 biopsies/patient. At 2 years, survival was 94.9%, and only 2.7% had graft dysfunction., Conclusions: Dual molecular testing demonstrated improved performance for ACR surveillance compared to single molecular testing. The use of dual noninvasive testing was associated with lower biopsy rates over time, excellent survival, and low incidence of graft dysfunction., (Copyright © 2024 International Society for the Heart and Lung Transplantation.

Background: Thirty-day outcomes with the investigational Intrepid transapical (TA) transcatheter mitral valve replacement (TMVR) system have previously demonstrated good technical success, but longer-term outcomes in larger cohorts need to be evaluated., Objectives: The authors sought to evaluate the 2-year safety and performance of the Intrepid TA-TMVR system in patients with symptomatic, ≥moderate-severe mitral regurgitation (MR) and high surgical risk., Methods: Patient eligibility was determined by local heart teams and approved by a central screening committee. Clinical events were adjudicated by an independent clinical events committee. Echocardiography was evaluated by an independent core laboratory., Results: The cohort included 252 patients that were enrolled at 58 international sites before February 2021 as part of the global Pilot Study (n = 95) or APOLLO trial (primary cohort noneligible + TA roll-ins, n = 157). Mean age was 74.2 years, mean STS-PROM was 6.3%, 60.3% were male, and 80.6% were in NYHA functional class III/IV. Most presented with secondary MR (70.1%), and nearly all had ≥moderate-severe MR (98.4%). All-cause mortality was 13.1% (30-day), 27.3% (1-year), and 36.2% (2-year). The 30-day ≥major bleeding event rate was 22.3%. Heart failure rehospitalization was 9.6% (30-day) and 36.2% (2-year). At 2 years, >50% of patients were alive with improvement in NYHA functional class (82.1%, class I/II), and all patients with available echocardiograms had ≤mild MR., Conclusions: This analysis represents the largest reported TA-TMVR experience with the longest follow-up in high-risk ≥moderate-severe MR patients. Early mortality and heart failure rehospitalizations were significant, exacerbated by early TA-related bleeding events; however, meaningful improvements in clinical outcomes and marked reductions in MR severity were observed through 2 years., Competing Interests: Funding Support and Author Disclosures This work was funded by Medtronic.

Orthotopic transcatheter tricuspid valve replacement (TTVR) devices have been shown to be highly effective in reducing tricuspid regurgitation (TR), and interest in this therapy is growing with the recent commercial approval of the first orthotopic TTVR. Recent TTVR studies report preexisting cardiac implantable electronic device (CIED) transvalvular leads in ∼35% of patients, with entrapment during valve implantation. Concerns have been raised regarding the safety of entrapping leads and counterbalanced against the risks of transvenous lead extraction (TLE) when indicated. This Heart Valve Collaboratory consensus document attempts to define the patient population with CIED lead-associated or lead-induced TR, describe the risks of lead entrapment during TTVR, delineate the risks and benefits of TLE in this setting, and develop a management algorithm for patients considered for TTVR. An electrophysiologist experienced in CIED management should be part of the multidisciplinary heart team and involved in shared decision making., Competing Interests: Funding Support and Author Disclosures Dr Hahn has received speaker fees from Abbott Structural, Baylis Medical, Edwards Lifesciences, Medtronic, Philips Healthcare, and Siemens Healthineers; and has institutional consulting contracts for which she receives no direct compensation with Abbott Structural, Edwards Lifesciences, Medtronic, and Novartis.

Context: Despite calls for integration into routine heart failure (HF) care, optimal palliative care delivery for people living with HF remains unclear., Objectives: Describe an innovative model of an embedded palliative care nurse practitioner (NP) within a HF team. Compare demographics and utilization among people hospitalized with HF receiving referral or embedded consultation., Methods: Using an electronic health record-based palliative care registry, we conducted descriptive analyses and t-tests and χ 2 tests, as appropriate, to examine bivariate associations between sociodemographic, clinical and utilization data of hospitalized people with HF receiving a traditional, referral-based palliative care consultation generated exclusively by the primary team vs. a novel, embedded-based consultation generated by collaboration between a palliative care NP and the advanced HF team at an urban, quaternary care academic medical center in New York City., Results: During the study period from January 1, 2019-December 31, 2021, consultation volume nearly doubled with 363 consults from traditional referrals and an additional 317 consults from the newly embedded NP. People in the embedded group, as compared to referral, were younger (mean age: 60.1 vs. 71.9 years (2019); 59.2 vs. 70.4 (2020); 61.3 vs. 69.6 (2021), p-value < 0.001), more functional (median Karnofsky Performance Status: 40% vs. 30%, p-value = 0.01 (2019); 40% vs 20%, p-value < 0.0001 (2020); 40% vs. 20%, p-value = 0.02 (2021)), more likely had capacity to designate a medical decision maker (56.4% vs. 20.6%, p-value < 0.001 (2020); 76.3% vs. 49.5%, p-value < 0.001 (2021)), received earlier consultation (median days before discharge: 9.5 vs. 4 (2019); 11 vs. 5 (2020); 7 vs. 3 (2021), p-value ≤ 0.001), and more likely to discharge home (60% vs. 26%, p-value ≤ 0.001 (2019); 62.7% vs 20.6%, p-value ≤ 0.001 (2020); 42.3% vs. 28%, p-value = 0.03 (2021))., Conclusion: Hospitalized people living with advanced HF who received an embedded palliative care consult were younger, had higher functional status and less illness severity compared to those served by a traditional, referral-based consult., (Copyright © 2023 American Academy of Hospice and Palliative Medicine.
