摘要
主动脉瓣钙化（AVC）是低流量、低梯度（LFLG）主动脉瓣狭窄（AS）的一种经指南认可的诊断工具，但其在LFLG亚型中的预后价值仍存在争议。在这项纳入457例经导管主动脉瓣置换术（TAVR）患者的回顾性队列研究中，在经典LFLG AS中，严重AVC与心力衰竭再住院率显著降低相关（校正风险比[HR]， 0.41; P = 0.023），而在矛盾LFLG AS中则无相关（校正风险比，0.76;P = 0.422）。当进行多巴酚丁胺应激超声心动图（DSE）时，AVC也与真重度AS相关。这些发现表明，即使在DSE结果不可用或不确定的情况下，仅AVC可以识别可能从TAVR获益的典型LFLG AS患者。
Aortic valve calcification (AVC) is a guideline-endorsed diagnostic tool in low-flow, low-gradient (LFLG) aortic stenosis (AS), but its prognostic value across LFLG subtypes remains debated. In this retrospective cohort of 457 patients undergoing transcatheter aortic valve replacement (TAVR), severe AVC was associated with significantly fewer heart failure rehospitalizations in classical LFLG AS (adjusted hazard ratio [HR], 0.41; P = .023) but not in paradoxical LFLG AS (adjusted HR, 0.76; P = .422). AVC also correlated with true-severe AS when dobutamine stress echocardiography (DSE) was performed. These findings suggest that AVC alone can identify classical LFLG AS patients likely to benefit from TAVR, even when DSE results are unavailable or inconclusive.
