Minimally Invasive Atrial Septal Defect Closure: A Single Center Experience

Abstract

Minimally Invasive Atrial Septal Defect Closure: A Single Center Experience Summary and Abstract Objective:In this study, we wanted to share the results of minimally invasive atrial septal defect closure in our clinic. Materials and methods: Thirty-six patients who underwent minimally invasive atrial septal defect closure in our clinic between September 2016 and September 2022 were included in the study. Patients who underwent atrial septal defect closure accompanying another cardiac anomaly were excluded from the study. Redo cases in which the sternum was opened before were excluded from the study. Demographic data, physical examination findings, transthoracic echocardiographic and angiographic examination data of the patients were obtained retrospectively from the database of our hospital. Patients with genetic anomalies were noted. This study was approved by the Medical and Health Sciences Research Board of our institution (Project no:KA22/400). Results: Thirty-six patients (male:11(31%), female:25(69%)) were included in the study. The median age of the patients was 57 months (IQR: 43-83 months) and the median body weight was 16 kg (IQR: 12.7-21.7 kg). Chromosomal anomaly was detected in two (5.5%) patients. A secundum atrial septal defect was detected in 31 (86%) patients, high venosum atrial septal defect in four (11%), and low venosum atrial septal defect in one (3%). Partial sternotomy was performed in 20 patients (56%), and total sternotomy was performed in 16 (44%). The median cardiopulmonary bypass time of the patients was 46.5 minutes (IQR: 36.8-57.2 minutes), and the median X-clamp times were 21.5 minutes (IQR: 15-28.7 minutes). Nine (25%) patients' defects were closed with a patch, and 27 (75%) patients' defects were closed primarily. No mortality was observed in any patient. The median hospital stay was 5 days (IQR: 4-5 days). Discussion: In our study, no mortality or morbidity was found in cases of atrial septal defect closure performed with minimally invasive method. Minimally invasive atrial septal defect closure can be performed with similar safety and better cosmetic results compared to the standard method.
