- The conceptual framework of proportionate versus disproportionate mitral regurgitation (MR) translates poorly to individual patients with heart failure (HF) and secondary MR. A novel index, the ratio of MR severity to left atrial volume (LAV), may identify patients with "disproportionate" MR and a higher risk of events. The objectives, therefore, were to investigate the prognostic impact of MR severity to LAV ratio on outcomes among HF patients with severe secondary MR randomized to transcatheter edge-to-edge repair (TEER) with the MitraClipTM device plus guideline-directed medical therapy (GDMT) vs. GDMT alone in the COAPT trial.The ratio of preprocedural regurgitant volume (RVol) to LAV was calculated from baseline transthoracic echocardiograms. The primary endpoint was 2-year covariate-adjusted rate of HF hospitalization (HFH).Among 567 patients, the median RVol/LAV was 0.67 (IQR 0.48-0.91). In patients randomized to GDMT alone, lower RVol/LAV was independently associated with an increased 2-year risk of HFH (adjHR: 1.77; 95% CI: 1.20-2.63). RVol/LAV was a stronger predictor of adverse outcomes than RVol or LAV alone. Treatment with TEER plus GDMT compared with GDMT alone was associated with lower 2-year rates of HFH both in patients with low and high RVol/LAV (Pinteraction=0.28). Baseline RVol/LAV ratio was unrelated to 2-year mortality, health status, or functional capacity in either treatment group.Low RVol/LAV ratio was an independent predictor of 2-year HFH in HF patients with severe MR treated with GDMT alone in the COAPT trial. TEER improved outcomes regardless of baseline RVol/LAV ratio.Trial Name: Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients With Functional Mitral Regurgitation (The COAPT Trial) (COAPT) ClinicalTrial.gov Identifier: NCT01626079 URL: https://clinicaltrials.gov/ct2/show/NCT01626079.

- Background: Risk scores may identify patients with mitral regurgitation (MR) who are at risk for adverse events, but who may still benefit from transcatheter edge-to-edge repair (TEER). We sought to cross-validate the MitraScore and COAPT risk score to predict adverse events in patients undergoing TEER. Methods: MitraScore validation was carried out in the COAPT population which included 614 patients with FMR who were randomized 1:1 to guideline-directed medical therapy (GDMT) with or without TEER and were followed for 2 years. Validation of the COAPT risk score was carried out in 1007 patients from the MIVNUT registry of TEER-treated patients with both FMR and degenerative MR who were followed for a mean of 2.1 years. The predictive value was assessed using the area under the receiver operating characteristic curve (AUC) plots. The primary outcome was all-cause mortality. Results: The MitraScore had fair to good predictive accuracy for mortality in the overall COAPT trial population (AUC, 0.67); its accuracy was higher in patients treated with TEER (AUC, 0.74) than GDMT alone (AUC, 0.65). The COAPT risk score had fair predictive accuracy for death in the overall MitraScore cohort (AUC, 0.64), which was similar in patients with FMR and degenerative MR (AUC, 0.64 and 0.66, respectively). There was a consistent benefit of treatment with TEER plus GDMT compared with GDMT alone in the COAPT trial population across all MitraScore risk strata. Conclusions: The COAPT risk score and MitraScore are simple tools that are useful for the prediction of 2-year mortality in patients eligible for or undergoing treatment with TEER.

- Background The incidence and implications of worsening renal function (WRF) after mitral valve transcatheter edge-to-edge repair (TEER) in patients with heart failure (HF) are unknown. Therefore, the aim of this study was to determine the proportion of patients with HF and secondary mitral regurgitation who develop persistent WRF within 30 days following TEER, and whether this development portends a worse prognosis. Methods and Results In the COAPT (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients With Functional Mitral Regurgitation) trial, 614 patients with HF and severe secondary mitral regurgitation were randomized to TEER with the MitraClip plus guideline-directed medical therapy (GDMT) versus GDMT alone. WRF was defined as serum creatinine increase ≥1.5× or ≥0.3 mg/dL from baseline persisting to day 30 or requiring renal replacement therapy. All-cause death and HF hospitalization rates between 30 days and 2 years were compared in patients with and without WRF. WRF at 30 days was present in 11.3% of patients (9.7% in the TEER plus GDMT group and 13.1% in the GDMT alone group; P=0.23). WRF was associated with all-cause death (hazard ratio [HR], 1.98 [95% CI, 1.3-3.03]; P=0.001) but not HF hospitalization (HR, 1.47 [ 95% CI, 0.97-2.24]; P=0.07) between 30 days and 2 years. Compared with GDMT alone, TEER reduced both death and HF hospitalization consistently in patients with and without WRF (Pinteraction=0.53 and 0.57, respectively). Conclusions Among patients with HF and severe secondary mitral regurgitation, the incidence of WRF at 30 days was not increased after TEER compared with GDMT alone. WRF was associated with greater 2-year mortality but did not attenuate the treatment benefits of TEER in reducing death and HF hospitalization compared with GDMT alone.

- Background Use of the modified American College of Cardiology (ACC)/American Heart Association (AHA) lesion classification as a prognostic tool to predict short- and long-term clinical outcomes after percutaneous coronary intervention in the modern drug-eluting stent era is uncertain. Methods and Results Patient-level data from 7 prospective, randomized trials were pooled. Clinical outcomes of patients undergoing single lesion percutaneous coronary intervention with second-generation drug-eluting stent were analyzed according to modified ACC/AHA lesion class. The primary end point was target lesion failure (TLF: composite of cardiac death, target vessel myocardial infarction, or ischemia-driven target lesion revascularization). Clinical outcomes to 5 years were compared between patients treated for noncomplex (class A/B1) versus complex (class B2/C) lesions. Eight thousand five hundred sixteen patients (age 63.1±10.8 years, 70.5% male) were analyzed. Lesions were classified as A, B1, B2, and C in 7.9%, 28.5%, 33.7%, and 30.0% of cases, respectively. Target lesion failure was higher in patients undergoing percutaneous coronary intervention of complex versus noncomplex lesions at 30 days (2.0% versus 1.1%, P=0.004), at 1 year (4.6% versus 3.0%, P=0.0005), and at 5 years (12.4% versus 9.2%, P=0.0001). By multivariable analysis, treatment of ACC/AHA class B2/C lesions was significantly associated with higher rate of 5-year target lesion failure (adjusted hazard ratio, 1.39 [95% CI, 1.17-1.64], P=0.0001) driven by significantly higher rates of target vessel myocardial infarction and ischemia-driven target lesion revascularization. Conclusions In this pooled large-scale analysis, treating complex compared with noncomplex lesions according to the modified ACC/AHA classification with second-generation drug-eluting stent was associated with worse 5-year clinical outcomes. This historical classification system may be useful in the contemporary era for predicting early and late outcomes following percutaneous coronary intervention.

- Although a 1-year duration of dual antiplatelet therapy (DAPT) is used in many patients after drug-eluting stent (DES) implantation, the evidence supporting this duration is uncertain.The authors investigated the risk-benefit profile of 1-year vs≤6-month DAPT after DES using 2 novel scores to risk stratify bleeding and ischemic events.Ischemic and bleeding risk scores were generated from ADAPT-DES (Assessment of Dual Antiplatelet Therapy With Drug-Eluting Stents), a multicenter, international, "all-comers" registry that enrolled 8,665 patients treated with DES. The risk-benefit profile of 1-year vs≤6-month DAPT was then investigated across risk strata from an individual patient data pooled dataset of 7 randomized trials that enrolled 15,083 patients treated with DES.In the derivation cohort, the ischemic score and the bleeding score had c-indexes of 0.76 and 0.66, respectively, and both were well calibrated. In the pooled dataset, no significant difference was apparent in any ischemic endpoint between 1-year and≤6-month DAPT, regardless of the risk strata. In the overall dataset, there was no significant difference in the risk of clinically relevant bleeding between 1-year and≤6-month DAPT; however, among 2,508 patients at increased risk of bleeding, 1-year compared with≤6-month DAPT was associated with greater bleeding (HR: 2.80; 95%CI: 1.12-7.13) without a reduced risk of ischemic events in any risk strata, including those with acute coronary syndromes. These results were consistent in a network meta-analysis.In the present large-scale study, compared with≤6-month DAPT, a 1-year duration of DAPT was not associated with reduced adverse ischemic events in any risk strata (including acute coronary syndromes) but was associated with greater bleeding in patients at increased risk of bleeding.

- Little is known regarding the risk of cerebrovascular events (CVE) in patients with heart failure and severe secondary mitral regurgitation treated with transcatheter edge-to-edge repair (TEER).The study sought to examine the incidence, predictors, timing, and prognostic impact of CVE (stroke or transient ischemic attack) in the COAPT (Cardiovascular Outcomes Assessment of the Mitraclip Percutaneous Therapy for HeartFailure Patients with Functional Mitral Regurgitation) trial.A total of 614 patients with heart failure and severe secondary mitral regurgitation were randomized to TEER plus guideline-directed medical therapy (GDMT) vs GDMT alone.At 4-year follow-up, 50 CVEs occurred in 48 (7.8%) of the 614 total patients enrolled in the COAPT trial; Kaplan-Meier event rates were 12.3% in the TEER group and 10.2 in the GDMT alone group (P=0.91). Within 30days of randomization, CVE occurred in 2 (0.7%) patients randomized to TEER and 0% randomized to GDMT (P=0.15). Baseline renal dysfunction and diabetes were independently associated with increased risk of CVE, while baseline anticoagulation was associated with a reduction of CVE. A significant interaction was present between treatment group and anticoagulation such that TEER compared with GDMT alone was associated with a reduced risk of CVE among patients with anticoagulation (adjusted HR: 0.24; 95%CI: 0.08-0.73) compared with an increased risk of CVE in patients without anticoagulation (adjusted HR: 2.27; 95%CI: 1.08-4.81; Pinteraction=0.001). CVE was an independent predictor of death within 30days after the event (HR: 14.37; 95%CI: 7.61, 27.14; P< 0.0001).In the COAPT trial, the 4-year rate of CVE was similar after TEER or GDMT alone. CVE was strongly associated with mortality. Whether anticoagulation is effective at reducing CVE risk after TEER warrants further study.(Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for HeartFailure Patients With Functional Mitral Regurgitation [The COAPT Trial] and COAPT CAS [COAPT); NCT01626079).
