Persistence of residual shunt at 6 and 12 months after transoesophageal echocardiography-guided percutaneous closure of a patent foramen ovale for cryptogenic stroke.

ABSTRACT:

Background

Young patients suffering from cryptogenic stroke alongside a patent foramen ovale (PFO) are often considered for percutaneous device closure to reduce the risk of stroke recurrence. Residual right-to-left shunt after device closure may persist in approximately a quarter of the patients at 6 months, and some may close at a later time point. This study aimed to assess the prevalence and persistence of residual right-to-left shunt after percutaneous PFO closure.

Methods

Consecutive patients undergoing transoesophageal echocardiography-guided PFO closure for cryptogenic stroke between 2006 and 2021, with echocardiographic follow-up including contrast bubble study and Valsalva manoeuvre, were enrolled. Follow-up transthoracic echocardiography was performed at 6 months
