Value of Subtype Classification of Intracardiac Partial Anomalous Pulmonary Venous Connection on Guiding the Surgical Options

Objectives:To investigate the clinical value of the subtype classification of intracardiac partial anomalous pulmonary venous connection(PAPVC)on the decision making on surgical procedures.Methods:This study retrospectively analyzed 46 children diagnosed as intracardiac PAPVC by transthoracic echocardiography at Beijing Children's Hospital from 2009 to 2019.Subtype classification was performed according to the pathological and anatomical characteristics of PAPVC,including pulmonary venous drainage site,atrial septal defect,and surgical methods.Results:There were 33 cases with pulmonary veins of typeⅠPAPVC with draining into the vena cava-right atrial junction.This type was further divided into overriding typeⅠPAPVC(n=26)and non-overriding typeⅠPAPVC(n=7)according to the presence or absence of vena cava sinus atrial septal defect.There were 10 cases of typeⅡPAPVC with draining into the right atrium posterior wall and 3 cases of typeⅢPAPVC with draining into the coronary sinus.Patch closure was performed for overriding type.Non-overriding type was treated with an open technique to establish the rim of the pulmonary veins.TypeⅡwas treated with a flap to cover above the orifices of the pulmonary veins.TypeⅢwas treated with incision of the coronary sinus wall.Conclusions:The subtype classification of PAPVC can guide the decision making on surgical procedures.
