        Morphological and morphometric study of pulmonary vein anatomy in relation to cardiac invasive and electrophysiological procedures

        Harshal Oza,Bhavik Doshi 대한해부학회 2023 Anatomy & Cell Biology Vol.56 No.4

        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 complicationsduring cardiac procedures. The aim of this study was to evaluate the PV anatomy along with anatomical variations inthe Indian population. Total 100 formalin fixed cadaveric hearts were examined. The number and pattern of the PVswere observed along with the measurement of their horizontal and vertical diameters. The ovality index for each PV wascalculated. Classical PV pattern was observed in 62% cases. Variant pattern like additional right middle PV pattern and leftcommon PV pattern were found in 20% and 10% cases respectively. A separate pattern with presence of both right middlePV and left common PV was observed in 6% cases. In the classical pattern right superior PV was the largest followed by rightinferior, left superior and left inferior PV. The additional right middle PV had the smallest diameter whereas the left commonPV had the largest diameter. Almost all the veins had greater vertical diameters in comparison to horizontal diameters. Thevariant PVs were oval and had greater ovality index compared to the normal PVs. In classical pattern 54.8% hearts whereas invariant pattern 79% hearts had one or more oval PV. The given data can help clinicians for planning and execution of variousinterventional and electrophysiological procedures involving PVs.
