Immediate Reversal of Hypoxemia With PFO Closure in Carcinoid Heart Disease and Platypnea-Orthodeoxia Syndrome
Puntos clave
This research aims to evaluate the effectiveness of percutaneous closure of a patent foramen ovale (PFO) in treating persistent hypoxemia associated with carcinoid heart disease.
Identified cases of persistent hypoxemia with negative pulmonary assessments.
Performed timely percutaneous closure of PFOs on eligible patients.
Monitored patients' oxygen levels post-procedure for improvements.
Patients showed immediate reversal of hypoxemia after the PFO closure.
Improvements in oxygen saturation were sustained over time.
No significant complications noted from the procedure.
Resumen
Consider a PFO in persistent hypoxemia despite a negative pulmonary work-up. Timely percutaneous closure may lead to rapid, sustained improvement.
