Plain-English summary
The WATCHMAN TruSeal Access System ANT, material number M635TS70040, GTIN 08714729965756, is being recalled across all non-expired batches. The system is intended to provide vascular and transseptal access for WATCHMAN Left Atrial Appendage Closure Devices with delivery systems. The recall covers 340,185 units distributed worldwide.
Boston Scientific identified a higher likelihood of air embolism events when procedures are performed without positive pressure-controlled ventilation. The company states that, according to published literature and clinical data, in percutaneous procedures requiring transseptal access to the left atrium under conscious or deep sedation, patients have an approximately three times higher risk in a US study of negative left atrium pressure and air ingress. The risk is described as especially prevalent in patients with pre-existing low left atrial pressure, hypovolemia and partial upper airway collapse. The FDA classified the action as Class I, its most serious category.
Hospitals and proceduralists should follow the manufacturer's updated instructions on ventilation during these procedures.
