摘要

房颤导管消融术前影像学检查常发现肺静脉（PV）变化。然而，以前未报道的罕见变异存在。本病例是首次报道的三个pv来自共同主干的实例。增强心脏计算机断层扫描显示左上、左下和右下pv起源于总干。此外，三维电解剖图显示了有趣的发现，显示导管消融前三个pv及其共同干是疤痕区域。罕见的普通PV可能在PV窦腔或主干内没有致心律失常的底物。

A catheter ablation case of confluent inferior and left superior pulmonary veins: a rare pulmonary vein variation.

Pulmonary vein (PV) variations are commonly detected by preoperative imaging modalities in catheter ablation for atrial fibrillation. However, rare variations that have not been previously reported exist. The present case is the first reported instance of three PVs originating from a common trunk. Contrast-enhanced cardiac computed tomography revealed that the left superior, left inferior, and right inferior PVs originated from the common trunk. Additionally, 3-dimensional electroanatomical mapping revealed interesting findings, showing that the three PVs and their common trunk were scarred areas prior to catheter ablation. The rare common PV may have no arrhythmogenic substrate in the PV antrum or common trunk.

期刊介绍： The Journal of Interventional Cardiac Electrophysiology is an international publication devoted to fostering research in and development of interventional techniques and therapies for the management of cardiac arrhythmias. It is designed primarily to present original research studies and scholarly scientific reviews of basic and applied science and clinical research in this field. The Journal will adopt a multidisciplinary approach to link physical, experimental, and clinical sciences as applied to the development of and practice in interventional electrophysiology. The Journal will examine techniques ranging from molecular, chemical and pharmacologic therapies to device and ablation technology. Accordingly, original research in clinical, epidemiologic and basic science arenas will be considered for publication. Applied engineering or physical science studies pertaining to interventional electrophysiology will be encouraged. The Journal is committed to providing comprehensive and detailed treatment of major interventional therapies and innovative techniques in a structured and clinically relevant manner. It is directed at clinical practitioners and investigators in the rapidly growing field of interventional electrophysiology. The editorial staff and board reflect this bias and include noted international experts in this area with a wealth of expertise in basic and clinical investigation. Peer review of all submissions, conflict of interest guidelines and periodic editorial board review of all Journal policies have been established.
