Transcatheter closure of patent vertical vein after repair of total anomalous pulmonary venous connection: a case series.

BACKGROUND AND

OBJECTIVES

Total anomalous pulmonary venous connection is a rare cyanotic CHD that requires surgical repair. An unligated vertical vein after total anomalous pulmonary venous connection surgery may help to decrease the episodes of post-operative pulmonary hypertensive crises, low cardiac output syndrome, and mortality. The aim was to assess long-term outcome and our post-operative transcatheter vertical vein closure experiences in five patients with repaired total anomalous pulmonary venous connection patients.

METHODS

A retrospective study was conducted in five cases with an unligated vertical vein following repair of supra-cardiac total anomalous pulmonary venous connection at our hospital from 2011 through 2018. Patients characteristics, cardiac catheterisation findings, surgical, and transcatheter procedural details were retrospectively analysed.

RESULTS

Transcatheter closure of the unligated vertical vein was technically successful in all the patients. Procedure-related complications were not observed in any of the patients. No long-term complication was found.

CONCLUSIONS

We suggest that transcatheter closure of the patent vertical vein is an effective and well-tolerated alternative to the surgical approach.
