Does a scoring system based on patient characteristics and echocardiographic findings predict optimal device size for percutaneous PFO closure?
A simple scoring system based on patient and echocardiographic characteristics can help select the optimally sized ASOC device for percutaneous PFO closure.
Hypothesis-generating for PFO device sizing; requires prospective validation before clinical adoption.
BACKGROUND: Patent foramen ovale (PFO) has been linked to cryptogenic stroke, and closure has been reported to improve clinical outcomes. However, there are no clear guidelines to direct device sizing. This study sought to use patient characteristics and echocardiographic findings to create a prediction score for device sizing. METHODS: This was a retrospective review of patients undergoing percutaneous PFO closure at our institution between July 2010 and December 2014. Demographic and clinical characteristics were recorded, and all pre- and intraprocedural echocardiography results were evaluated. CONCLUSIONS: A simple scoring system may be used to select an optimally sized device for percutaneous PFO closure using the ASOC device.

Venturini et al. (2016) conducted an observational in Patent foramen ovale. Scoring system for device sizing was evaluated on Optimal device sizing prediction (p== 0.006). A simple scoring system based on patient characteristics and echocardiographic findings may be used to select an optimally sized ASOC device for percutaneous PFO closure (p=0.006).
