Class I U.S. Food and Drug Administration

Boston Scientific Corporation Watchman FXD Curve Access System Dbl, US recall: Boston Scientific has identified a higher likelihood of air embolism events

Recall published 1+ years ago

Boston Scientific has identified a higher likelihood of air embolism events when procedures are performed without positive pressure-controlled ventilation. According to published literature and clinical data, in percutaneous procedures requiring transseptal access to the left atrium when conscious or deep sedation is used, patients have an approximately three-times higher risk (U.S. study) of negative left atrium pressure and air ingress. This risk is especially prevalent in patients with pre-existing low left atrial pressure, hypovolemia, and partial upper airway collapse.

The hazard: Fall or tip-over hazard

The recall is about structural failure — a frame, joint, leg or lock that does not hold under ordinary use.

What the notice says: Boston Scientific has identified a higher likelihood of air embolism events when procedures are performed without positive pressure-controlled ventilation. According to published literature and clinical data, in percutaneous procedures requiring transseptal access to the left atrium when conscious or deep sedation is used, patients have an approximately three-times higher risk (U.S. study) of negative left atrium pressure and air ingress. This risk is especially prevalent in patients with pre-existing low left atrial pressure, hypovolemia, and partial upper airway collapse.

Why it matters: The product can tip, collapse or give way under normal use. Furniture tip-overs in particular kill and injure young children, usually when a child climbs on an open drawer.

Symptoms and when to call a doctor

After a fall or a tip-over involving a child, watch for a headache that gets worse, repeated vomiting, drowsiness that is hard to rouse, confusion, unequal pupils, clear fluid from the nose or ear, or a seizure, and call 911 if any of these appear. Any fall onto the head in a baby under one, or any loss of consciousness at any age, needs to be assessed the same day.

What to do about Fall

Boston Scientific Corporation — The recall is about structural failure — a frame, joint, leg or lock that does not hold under ordinary use.

  1. Stop using the product and, if it is furniture, move it out of a child’s room until the remedy is done.
  2. Anchor tall furniture to the wall with a tip-over restraint — this is worth doing for every chest and bookcase in the house, not just this one.
  3. Keep TVs, toys and anything else tempting off the top of tall furniture, because that is what draws a child to climb.
  4. Inspect similar units from the same range, since a weak joint or fastener usually affects a whole production run.

How the remedy works

CPSC recalls specify one of three remedies, and which one you get is not negotiable — but how smoothly it goes often is.

  • A refund means the purchase price back, sometimes prorated by age for durable goods. Ask how they calculated it if the figure looks low.
  • Return shipping is the company’s cost. If you are asked to pay it, push back.
  • A repair kit is shipped free and is designed to be fitted at home; if you cannot fit it, ask whether they will arrange installation.
  • A replacement is usually the current model, not the recalled one. Confirm the replacement is not itself under recall.
