BACKGROUND: Transcatheter tricuspid valve replacement (TTVR) abolishes tricuspid regurgitation (TR) and has emerged as a definitive treatment for TR. OBJECTIVES: The purpose of this multicenter, observational study was to determine the clinical characteristics and short-term outcomes of patients with TR screened for TTVR. METHODS: Patients underwent TTVR screening at 7 centers on a compassionate-use basis. The primary endpoints were NYHA functional class and TR grade at 30-day follow-up. Secondary endpoints included all-cause mortality, heart failure hospitalization, technical success, and reasons for TTVR screening failure. RESULTS: A total of 149 patients (median age 79 years [Q1-Q3: 72-84 years], 54% women) underwent TTVR screening. The TTVR screening failure rate was 74%, mainly related to large tricuspid annular diameter. Patients undergoing TTVR (n = 38) had significant functional improvements (NYHA functional class I or II from 21% to 68%; P < 0.001), with TR ≤1+ in 97% at 30-day follow-up (P < 0.001 from baseline). Technical success was achieved in 91%, with no intraprocedural mortality or conversion to surgery. At 30-day follow-up, mortality was 8%, heart failure hospitalization 5%, major bleeding 18%, and reintervention 9%. Patients who failed screening for TTVR and subsequently underwent "bailout" transcatheter edge-to-edge repair (n = 26) had favorable outcomes (NYHA functional class I or II from 27% to 58%; P < 0.001), with TR ≤1+ in 43% at 30-day follow-up (P < 0.001 from baseline). CONCLUSIONS: This first real-world report of TTVR screening demonstrated a high screening failure rate, mainly related to large tricuspid annular diameter. Patients undergoing TTVR had superior TR reduction and symptom alleviation compared with bailout tricuspid transcatheter edge-to-edge repair, at the cost of greater procedural complications.
背景:经导管三尖瓣置换术(TTVR)消除了三尖瓣反流(TR),已成为 TR 的一种明确治疗方法。
目的:这项多中心观察性研究的目的是确定接受 TTVR 筛查的 TR 患者的临床特征和短期结局。
方法:7 家中心以同情使用为基础对患者进行 TTVR 筛查。主要终点为 30 天随访时的纽约心脏协会(NYHA)心功能分级和 TR 分级。次要终点包括全因死亡率、心力衰竭住院、技术成功率和 TTVR 筛查失败的原因。
结果:共 149 例患者(中位年龄 79 岁[四分位间距(IQR):72-84 岁],54%为女性)接受了 TTVR 筛查。TTVR 筛查失败率为 74%,主要与三尖瓣环直径较大有关。接受 TTVR 治疗的患者(n=38)心功能显著改善(NYHA 心功能分级 I 或 II 级从 21%增至 68%;P<0.001),30 天随访时 TR 均≤1+的比例为 97%(与基线相比,P<0.001)。技术成功率为 91%,无术中死亡或转为外科手术。30 天随访时死亡率为 8%,心力衰竭住院率为 5%,主要出血率为 18%,再次介入率为 9%。因 TTVR 筛查失败而随后接受“抢救”经导管缘对缘修复术的患者(n=26)结局良好(NYHA 心功能分级 I 或 II 级从 27%增至 58%;P<0.001),30 天随访时 TR 均≤1+的比例为 43%(与基线相比,P<0.001)。
结论:这是 TTVR 筛查的首个真实世界报告,结果显示筛查失败率较高,主要与三尖瓣环直径较大有关。与抢救性经导管三尖瓣缘对缘修复术相比,接受 TTVR 的患者 TR 减轻和症状缓解更优,但手术并发症更多。
