Abstract

Pulmonary veins (PVs) and their myocardial sleeves play an important role in the development of atrial fibrillation. Hence, detailed knowledge of PV anatomy is required to improve the procedural success rate and prevent complications during cardiac procedures. The aim of this study was to evaluate the PV anatomy along with anatomical variations in the Indian population. Total 100 formalin fixed cadaveric hearts were examined. The number and pattern of the PVs were observed along with the measurement of their horizontal and vertical diameters. The ovality index for each PV was calculated. Classical PV pattern was observed in 62% cases. Variant pattern like additional right middle PV pattern and left common PV pattern were found in 20% and 10% cases respectively. A separate pattern with presence of both right middle PV and left common PV was observed in 6% cases. In the classical pattern right superior PV was the largest followed by right inferior, left superior and left inferior PV. The additional right middle PV had the smallest diameter whereas the left common PV had the largest diameter. Almost all the veins had greater vertical diameters in comparison to horizontal diameters. The variant PVs were oval and had greater ovality index compared to the normal PVs. In classical pattern 54.8% hearts whereas in variant pattern 79% hearts had one or more oval PV. The given data can help clinicians for planning and execution of various interventional and electrophysiological procedures involving PVs.

肺静脉解剖的形态学和形态计量学研究与心脏侵入性和电生理程序的关系。
肺静脉及其心肌袖在心房颤动的发展中起着重要作用。因此,需要详细了解PV解剖结构,以提高手术成功率并预防心脏手术中的并发症。本研究的目的是评估印度人群的PV解剖结构以及解剖变异。共检查了100具福尔马林固定的尸体心脏。观察PV的数量和模式以及对其水平和垂直直径的测量。计算每个PV的椭圆度指数。62%的病例观察到典型的PV模式。在20%和10%的病例中分别发现了变异型,如附加的右中PV型和左共同PV型。在6%的病例中观察到同时存在右中PV和左共同PV的单独模式。在经典模式中,右上PV最大,其次是右下PV、左上PV和左下PV。附加的右侧中间PV的直径最小,而左侧共同PV的直径最大。与水平直径相比,几乎所有静脉的垂直直径都更大。与正常PV相比,变异PV是椭圆形的,并且具有更大的椭圆度指数。在经典模式中,54.8%的心脏有一个或多个椭圆形PV,而在变异模式中,79%的心脏有。给定的数据可以帮助临床医生规划和执行涉及PV的各种介入和电生理程序。
