JAHA:成年先心病患者房性心动过速的特征研究

2019-02-18 不详 MedSci原创

房性心动过速(AT)在成年先天性心脏病患者中比较常见,且不容易治疗。本研究旨在使用超高密度标测来评估AT的机制,并研究基质特征是否与消融结果相关。本研究共在23例成年先心病患者中通过超高密度标测检测到50个AT,并将患者分成两组:A组为单个AT诱导的患者(n=12),B组为≥2个AT诱导的患者(n=11)。经过平均12个月时间的随访,与A组患者相比,B组患者的手术时间、低压区(0.05–0.5 m

房性心动过速(AT)在成年先天性心脏病患者中比较常见,且不容易治疗。本研究旨在使用超高密度标测来评估AT的机制,并研究基质特征是否与消融结果相关。

本研究共在23例成年先心病患者中通过超高密度标测检测到50个AT,并将患者分成两组:A组为单个AT诱导的患者(n=12),B组为≥2个AT诱导的患者(n=11)。经过平均12个月时间的随访,与A组患者相比,B组患者的手术时间、低压区(0.05–0.5 mV)和按体积索引的低压区更高(159 [147–180] vs 412 [352–420] min, P<0.001, 22.6 [12.2–29.8] vs 54.2 [51.1–61.6] cm2, P=0.014 和0.17 [0.12–0.21] versus 0.26 [0.23–0.27] cm2/mL, P=0.024 ),致密疤痕(<0.05 mV)和心房容积在两组患者中无明显差异。

研究结果显示,对于伴发房性心动过速的成年先心病患者,更大的低压区而非致密疤痕与多发AT呈相关性。
