Open heart surgery or echocardiographic transthoracic or percutaneous closure in secundum atrial septal defect: a developing approach in one Chinese hospital

Cosmetic and shoulder functional outcomes in posterolateral minithoracotomy atrial septal defect closure: A retrospective study

BACKGROUND AND AIM

Transcatheter device closure has become the first treatment option for atrial septal defects (ASD). Surgical ASD closure, although still implemented, is cosmetically inferior to transcatheter closure. This study aimed to evaluate the feasibility as well as short- and long-term clinical outcomes of the right posterolateral minithoracotomy approach for surgical ASD closure.

METHODS

In total, 102 consecutive patients underwent posterolateral minithoracotomy for ASD between January 2014 and December 2021 at our center. Early surgical outcomes, cosmetic findings, and skin perception were evaluated over 1 year of postoperative follow-up using a self-satisfaction survey (1: very good, 2: good, 3: normal, 4: not good, 5: bad), Cavendish score, and shoulder joint function (angles of flexion, extension, and abduction).

RESULTS

No patient required conversion to median sternotomy. Only one patient required reoperation due to bleeding. Postoperative echocardiography revealed no residual shunt at discharge in all patients. The mean follow-up period was 3.7 years (range: 0.3-7.1 years), during which the questionnaire was answered by 69 of 98 patients who were evaluated after more than 1 year. The mean self-satisfaction survey scores for cosmetic findings and skin perception were 1.3 ± 0.6 and 1.2 ± 0.5, respectively. The Cavendish score was under Grade 1 in all patients. Shoulder flexion and abduction were normal at 180° in all patients, except one, while extension was normal at 50° in all patients, except three.

CONCLUSIONS

Our procedure achieved not only good early surgical outcomes but also excellent long-term cosmetic and shoulder function results.

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.
