Patent Foramen Ovale Closure Challenged by Left Atrial Chord
In a 22-year-old woman suffering from ischemic stroke affecting the posterior cerebral artery, clinical work-up ruled out cardiovascular and neurological pathologies except patent foramen ovale (PFO) with septal aneurysm and complete bubble filling of the left atrium as demonstrated by echocardiography. The patient was scheduled for transcatheter PFO closure. Peri-interventional 3-dimensional transesophageal echocardiography revealed a PFO tunnel and a left atrial chord keeping the PFO open, with consequent continuous left to right shunting (A to C; Online Video 1). Balloon sizing demonstrated a tunnel diameter of 16 mm (D...

Transesophageal Echocardiography in Cryptogenic Stroke and Patent Foramen Ovale: Analysis of Putative High-Risk Features From the Risk of Paradoxical Embolism Database Structural Heart Disease
Conclusions— We found no evidence that the proposed transesophageal echocardiography risk markers of large PFO size, hypermobile septum, and presence of right-to-left shunt at rest are associated with clinical features suggesting that a CS is PFO-attributable. Additional tools to describe PFOs may be useful in helping to determine whether an observed PFO is incidental or pathogenically related to CS.
