伴下腔静脉滤器经上腔静脉路径成功消融右侧旁路1例

A case with inferior vena cava filter of right accessory pathway ablation through superior vena cava approach

患者因反复胸闷胸痛7年、心悸2 h入院。临床诊断为阵发性室上性心动过速(PSVT)。患者于20年前植入下腔静脉滤器。电生理检查明确诊断为右侧隐匿性旁道介导的房室折返性心动过速(顺向性)。后通过上腔静脉入路成功消融。对于难以通过下腔静脉入路消融的患者来说,上腔静脉入路可能是一种安全、有效和可行的方法。

A patient was admitted to the hospital with a history of repeated chest tightness and pain for 7 years,accompanied by palpitations lasting 2 hours.Clinical diagnosis revealed paroxysmal supraventricular tachycardia(PSVT).The patient had an inferior vena cava filter implanted 20 years ago.A clear diagnosis was established through electrophysiological examination,indicating right concealed accessory pathway-mediated atrioventricular reentrant tachycardia(anterograde).Successful ablation was performed through the superior vena cava approach.Therefore,the superior vena cava approach may be considered a safe,effective,and feasible method for patients who are challenging to ablate via the inferior vena cava approach.
