Transcatheter versus surgical closure of atrial septal defects: a systematic review and meta-analysis of clinical outcomes.

BACKGROUND: Atrial septal defects are a common form of CHD and dependent on the size and nature of atrial septal defects, closure may be warranted. The paper aims to compare outcomes of transcatheter versus surgical repair of atrial septal defects. METHODS: A comprehensive electronic literature search was conducted. Primary studies were included if they compared both closure techniques. Primary outcomes included procedural success, mortality, and reintervention rate. Secondary outcomes included residual defect and mean hospital stay. RESULTS: A total of 33 studies were included in meta-analysis. Mean total hospital stay was significantly shorter in the transcatheter cohort across both the adult (95% confidence interval, mean difference -4.05 (-4.78, -3.32) p < 0.00001) and paediatric populations (95% confidence interval, mean difference -4.78 (-5.97, -3.60) p < 0.00001). There were significantly fewer complications in the transcatheter group across both the adult (odds ratio 0.45, 95% confidence interval, [0.28, 0.72], p < 0.00001) and paediatric cohorts (odds ratio 0.26, 95% confidence interval, [0.14, 0.49], p < 0.00001). No significant difference in overall mortality was found between transcatheter versus surgical closure across the two groups, adult (odds ratio 0.76, 95% confidence interval, [0.40, 1.45], p = 0.41), paediatrics (odds ratio 0.62, 95% confidence interval, [0.21, 1.83], p = 0.39). CONCLUSION: Both transcatheter and surgical approaches are safe and effective techniques for atrial septal defect closure. Our study has demonstrated the benefits of transcatheter closure in terms of lower complication rates and mean hospital stay. However, surgery still has a place for more complex closure and, as we have demonstrated, shows no difference in mortality.

Congenitally Malformed Hearts: Aspects of Teaching and Research Involving Medical Students.

To appreciate congenital heart disease fully, a detailed understanding of the anatomical presentation, as well as the physiology, is required. This is often introduced at an advanced stage of training. Professor Anderson has been influential in the Clinical Anatomy Intercalated BSc programme at the University of Birmingham, in particular in his teaching on Sequential Segmental Analysis. This article describes the experiences of the latest cohort of students on this programme, who undertook varying research projects using the Birmingham Cardiac Archive, with the guidance of Professor Anderson. The projects outlined include various aspects of isomerism, encompassing both the cardiac and abdominal manifestations, as well as details of congenitally corrected transposition of the great arteries and prenatally diagnosed right aortic arch and double arch. These studies all aimed to increase the knowledge base of their respective cardiac malformations and provide a basis for further research.

Outcomes of cardiac surgery in Jehovah's Witness patients: A review.

OBJECTIVE: To review current literature evidence on outcomes of cardiac surgery in Jehovah's Witness patients. METHODS: A comprehensive electronic literature search was done from 2010 to 20th August 2020 identifying articles that discussed optimisation/outcomes of cardiac surgery in Jehovah's Witness either as a solo cohort or as comparative to non-Jehovah's Witnesses. No limit was placed on place of publication and the evidence has been summarised in a narrative manner within the manuscript. RESULTS: The outcomes of cardiac surgery in Jehovah's Witness patients has been described, and also compared, to non-Witness patients within a number of case reports, case series and comparative cohort studies. Many of these studies note no significant differences between outcomes of the two groups for a number of variables, including mortality. Pre-, intra and post-operative optimisation of the patients by a multidisciplinary team is important to achieve good outcomes. CONCLUSION: The use of a bloodless protocol for Jehovah's Witnesses does not appear to significantly impact upon clinical outcomes when compared to non-Witness patients, and it has even been suggested that a bloodless approach could provide advantages to all patients undergoing cardiac surgery. Larger cohorts and research across multiple centres into the long term outcomes of these patients is required.
