Concurrent Patent Foramen Ovale and Pulmonary Arteriovenous Malformation Etiology
Key Points
To investigate the relationship between patent foramen ovale and pulmonary arteriovenous malformations as congenital abnormalities.
Review of medical literature on PFO and PAVM
Analysis of incidence rates
Assessment of clinical implications related to shunting
Identified PFO and PAVM as co-occurring conditions
Documented increased risk of paradoxical embolism in individuals with both
Highlighted need for further research on their etiology
Abstract
Patent foramen ovale (PFO) and pulmonary arteriovenous malformations (PAVMs) are congenital vascular abnormalities that can lead to right-to-left shunting, potentially causing paradoxical embolism.
