Right ventricular-pulmonary artery coupling (RVPAC) predicts outcomes after transcatheter tricuspid valve edge-to-edge repair (T-TEER), but its role in patient selection remains unclear.
The aim of this study was to evaluate the prognostic implications of RVPAC in a European registry of patients with tricuspid regurgitation undergoing either T-TEER or medical management.
Among 1,885 patients with tricuspid regurgitation (n = 585 medical, n = 1,300 T-TEER), 946 were propensity matched (1:1). RVPAC, assessed as the ratio of tricuspid annular plane systolic excursion to systolic pulmonary artery pressure was analyzed for its association with 1-year mortality.
RVPAC was significantly associated with mortality (HR: 0.11; 95% CI: 0.04-0.29; P < 0.01), with an optimized cutoff of 0.41 mm/mm Hg. Mortality differed significantly by RVPAC in both treatment groups (log-rank P < 0.01). Across RVPAC tertiles (<0.32, 0.32-0.46, and >0.46 mm/mm Hg), tricuspid annular plane systolic excursion increased (14 mm [Q1-Q3: 12-17 mm] vs 18 mm [Q1-Q3: 15-20 mm] vs 21 mm [Q1-Q3: 18-24 mm]; P < 0.01), while systolic pulmonary artery pressure (60 mm Hg [Q1-Q3: 50-70 mm Hg] vs 45 mm Hg [Q1-Q3: 40-52 mm Hg] vs 34 mm Hg [Q1-Q3: 29-41 mm Hg]; P = 0.30) and kidney function (43 mL/min/m [Q1-Q3: 30-57 mL/min/m] vs 49 mL/min/m [Q1-Q3: 38-67 mL/min/m] vs 53 mL/min/m [Q1-Q3: 40-69 mL/min/m]; P = 0.03) declined. Mortality was highest in the low RVPAC tertile, with no difference between treatment modalities (HR: 1.04; 95% CI: 0.68-1.61; P = 0.85). T-TEER was associated with better survival than medical management in the intermediate RVPAC tertile (HR: 0.54; 95% CI: 0.31-0.94; P = 0.03). This difference persisted but weakened in the high RVPAC tertile, with the overall most favorable outcomes (HR: 0.69; 95% CI: 0.35-1.36; P = 0.27).
Poorer RVPAC reflects higher baseline risk and mortality, regardless of treatment. T-TEER is associated with better survival across a range of RVPAC values, including those less than previously suggested thresholds.
右心室-肺动脉耦合(RVPAC)可预测经导管三尖瓣缘对缘修复术(T-TEER)后的预后,但它在患者选择中的作用仍不明确。
本研究旨在评估RVPAC在欧洲一项三尖瓣反流患者登记研究中的预后意义,这些患者接受了T-TEER或药物治疗。
在1885例三尖瓣反流患者中(585例接受药物治疗,1300例接受T-TEER),946例进行了倾向匹配(1:1)。分析RVPAC(评估为三尖瓣环平面收缩期位移与收缩期肺动脉压之比)与1年死亡率的相关性。
RVPAC与死亡率显著相关(HR:0.11;95%CI:0.04-0.29;P<0.01),最佳截断值为0.41mm/mm Hg。两个治疗组中,RVPAC不同,死亡率有显著差异(对数秩检验P<0.01)。在RVPAC三分位数(<0.32、0.32-0.46和>0.46mm/mm Hg)中,三尖瓣环平面收缩期位移增加(14mm[第一四分位数-第三四分位数:12-17mm]对18mm[第一四分位数-第三四分位数:15-20mm]对21mm[第一四分位数-第三四分位数:18-24mm];P<0.01),而收缩期肺动脉压(60mm Hg[第一四分位数-第三四分位数:50-70mm Hg]对45mm Hg[第一四分位数-第三四分位数:40-52mm Hg]对34mm Hg[第一四分位数-第三四分位数:29-41mm Hg];P=0.30)和肾功能(43mL/min/m[第一四分位数-第三四分位数:30-57mL/min/m]对49mL/min/m[第一四分位数-第三四分位数:38-67mL/min/m]对53mL/min/m[第一四分位数-第三四分位数:40-69mL/min/m];P=0.03)下降。低RVPAC三分位数组的死亡率最高,治疗方式之间无差异(HR:1.04;95%CI:0.68-1.61;P=0.85)。在中等RVPAC三分位数组中,T-TEER与比药物治疗更好的生存率相关(HR:0.54;95%CI:0.31-0.94;P=0.03)。这种差异在高RVPAC三分位数组中持续存在但减弱,总体预后最有利(HR:0.69;95%CI:0.35-1.36;P=0.27)。
RVPAC较差反映了较高的基线风险和死亡率,与治疗无关。在一系列RVPAC值范围内,包括那些低于先前建议阈值的值,T-TEER与更好的生存率相关。
