Percutaneous closure of atrial septal defect: a consensus document of the joint group of experts from the Association of Cardiovascular Interventions and the Grown-Up Congenital Heart Disease Section of the Polish Cardiac Society

Abstract

ABSTRACT Atrial septal defect is the most common congenital heart lesion in adults. Although atrial septal defect closure is recommended in those with right heart enlargement or paradoxical embolism, data informing such indications in adults are quite limited. This population has many unique characteristics and needs. In recent years, significant progress has been made with regard to diagnostic modalities that facilitate the diagnostic workup of these patients. However, the decision‑making process, especially in selected adult patients population (advanced age, various concomitant diseases, poor LV function [both systolic and diastolic], pulmonary hypertension, concomitant arrhythmias or multiple defects, or deficient rims) is still not easy. Available data are predominantly focused on imaging endpoints and short‑term morbidity and mortality rather than long‑‑term. The evidence base for outcomes with or without defect closure comes from various studies with different observation periods. Moreover, the clinical experience in diagnosing and treating that subgroup of patients is inhomogeneous between individual physicians (cardiologists, imaging specialists, operators) and between small and large experience centers. In the view of the above, the joint group of experts from the Association of Cardiovascular Interventions and the Grown‑Up Congenital Heart Disease Section of the Polish Cardiac Society developed the following consensus opinion in order to standardize the principles of diagnosis, indications for treatment, methods of performing procedures, and tenets of postoperative care in Poland.
