FDA Announces Recall of Boston Scientific's Cryoablation Product ---POLARx ExistsRisk of esophageal injury (Atrial Esophageal Fistula), and has already created7 patients were injured and 4 died. Therefore, the FDA ruledBoco'sPOLARxand POLARx-FIT Cryoablation CatheterLevel 1 Recall.

However, this Level 1 recall does not involve a product recall but requires Boston Scientific to update.POLARxInstructions for Use, urging customers to continue to comply with these updated instructions.

The following is the updated content from Boston Scientific.

This Boston Scientific update manualEmphasized the importance of "validating balloon position, esophageal monitoring, and phrenic nerve monitoring."In addition, it was warned that ablation should not be repeated immediately at the same location, and ablation should be stopped if the balloon temperature drops to -65°C.

This recall does not involve removing these devices from the market.On the contrary, Boston Scientific has updated the instructions for use and urged customers to continue to comply with these updated instructions.

ActuallyAtrial-esophageal fistula is a severe complication inevitably associated with cryoablation, and at least the probability of its occurrence can be reduced through collaborative approaches. MedtronicArctic FrontThis complication also existed in the series of products, and in the early stages, it also led to patient deaths. Later, through continuous optimization of the product and its usage methods, it was possible to...The incidence of atrial-esophageal fistula, a complication, has significantly decreased.

This is why PFA technology was welcomed by doctors as soon as it came out. Because PFA is extremely safe, it does not have serious complications that thermal ablation may cause (which could lead to patient death). Even if Boston Scientific or Medtronic continuously upgrades and optimizes cryoablation technology, this product will eventually be eliminated by history.

Fortunately, both Boston Scientific and Medtronic are pioneers in PFA and can fully afford to lose their cryoablation products because their PFA products will capture more of the electrophysiology ablation market for them.
