Impact of social characteristics on the treatment of patients with ischaemic events and patent foramen ovale.

2012 
OBJECTIVE: Percutaneous closure of a patent foramen ovale (PFO) is a technically simple and safe procedure. PFO is a common finding present in up to one third of the population. Although several conditions such as stroke, migraine, and sleep apnoea have been associated with a PFO, as underlined by observational studies, no causal relationship has been documented so far. As this setting may potentially leave more space for the involved physicians for the choice of treatment, we hypothesized that social characteristics of the patient with a PFO might play a role. METHODS: We retrospectively analysed the data of 153 patients with a cerebrovascular and/or peripheral ischaemic event with the diagnosis of a PFO as documented in echocardiography from 2000 until 2005 at the University Hospital in Zurich, Switzerland. RESULTS: Forty-four patients (= 23%) underwent catheter-based PFO closure. There was no significant difference with respect to age ( or =60 years: P= 0.234, ns), gender (P = 0.356, ns) and insurance status (<40 years: P= 0.15, ns; 40-59 years: P= 0.37, ns; 60 years: P = 0.26, ns) between those who underwent percutaneous PFO closure and those who did not. CONCLUSION: We conclude from this single-centre experience that social characteristics of patients only have a marginal impact on the indication of percutaneous closure of a PFO, if at all.
