Transcatheter Closure of Atrial Septal Defect with Amplatzer Device in Adolescence and Adults: Short Term Results: MCVTC Experience

Abstract

Introduction: Atrial septal defect (ASD) is one of the common congenital heart diseases accounting for 8% to 10% of total congenital heart disease at birth and one of the most common diseases in adulthood. Ostium Secundum (OS) ASD has been successfully closed surgically for over several decades. But even though the results are better, it is associated with discomfort, morbidity, and a thoracotomy scar. Transcatheter closure in these patients has advanced rapidly in recent years and represents a growing field in invasive cardiology. Methods: This prospective study was conducted at Manmohan cardiothoracic vascular and transplant center, Maharajgung, Kathmandu, Nepal. Fifty-two (52) patients with a diagnosis of OS ASD assessed for device closure. Patients underwent transthoracic and trans oesophageal echocardiography for the defect location, size, number, and associated anomalies. All patients with OS ASD fulfilling the inclusion criteria enrolled for device closure. The procedure conducted under fluoroscopy and transesophageal guidance. The cases were followed up at 3 and 6 months, reassessed clinically and by echocardiography for any complications. Results: The patients with ASD who enrolled in this study belonged to the age group of 14 to 63 years. The device closure attempted in 46 patients, and the remaining six patients excluded from the procedure due to unsuitable anatomy after GA guided TEE done. Among 46 patients, 44 (95%) had successful device closure. The mean age of the patient was 35.7+ 10 and 33 (71.7%) female, with 13 (28.3%) males. Conclusions: The transcatheter device closure of ASD in adolescents and adults has a high success rate with fewer complications and found to be safely documented during immediate and short term follow up. However, long terms follow up is required to conclude it.
