Surgical closure of ASD’s and concomitant procedures needed in adults: A 3-year Cardiac Centre experience

Abstract

Objective: The study aims to evaluate the surgical closure of Atrial Septal Defect (ASD) and concomitant surgical procedures needed at Cardiac Care Centre. Introduction: An ASD is a hole of variable size in the atrial septum. A patent foramen ovale that is functionally closed by overlapping of limbic tissue superiorly and the valve of the fossa oval inferiorly (in response to the normal left-to-right atrial pressure gradient) is excluded. ASDs generally permit left-to-right shunting at the atrial level. Partial anomalous pulmonary venous connection (PAPVC) is a condition in which some but not all pulmonary veins connect to the right atrium or its tributaries, rather than to the left atrium. Methodology: A prospective cohort study was done at Tabba heart institute. 115 consecutive patients were reviewed and investigated. All the patients with surgical closure of ASD and concomitant surgical procedures who returned for follow-up from June 2011 to May 2016 in the study were included as population sample. Results: Total ASD repair only patients were 80 and patients who needed concomitant procedures too were 35. The size of the defect ranged from 3mm to 58mm, with a mean of 26.96±11.02mm. The relative frequencies of different ASDs were secundum 57 (80.2%), primum 4 (5.6%), and sinus venosus 10 (14.08%). Major post-operative complications by Age group and by procedure were evaluated and presented. Conclusion: It was concluded from our results that surgical repair of atrial septal defects and its variants is associated with very low morbidity in different age groups due to its excellent results.
