Key result
An esophageal temperature-guided safety algorithm for high-intensity focused ultrasound failed to prevent lethal complications, including one atrial-to-esophageal fistula and one unexplained death.
Why the study?
Does an esophageal temperature-guided safety algorithm prevent severe complications during high-intensity focused ultrasound for pulmonary vein isolation in patients with atrial fibrillation?
Observational (n=28)
Does an esophageal temperature-guided safety algorithm prevent severe complications during high-intensity focused ultrasound for pulmonary vein isolation in patients with atrial fibrillation?
An esophageal temperature-guided safety algorithm failed to prevent lethal complications during HIFU for PVI, indicating the technology currently does not meet safety standards for AF treatment.
No takes yet. Share an insight, caveat, or question.
Esophageal temperature monitoring may not avert fatal HIFU complications; leaves open whether alternative energies or protocols can achieve safe PVI.
Neven et al. (2010) conducted an observational in Atrial fibrillation (n=28). High-intensity focused ultrasound (HIFU) with esophageal temperature-guided safety algorithm was evaluated on Safety and complications. An esophageal temperature-guided safety algorithm for high-intensity focused ultrasound failed to prevent lethal complications, including one atrial-to-esophageal fistula and one unexplained death.
