At first glance, the results of the CLOSURE-AF study would seem to spell doom for left atrial appendage closure devices for patients at risk of stroke, but there is some noise in the signal, including that the devices used in the study no longer represent the state of the med-tech art.

The ink is barely dry on the draft Medicare physician fee schedule for 2026, but three cardiology societies blasted the draft for cutting rates for left atrial appendage closure procedures – a move they said needlessly endangers patients.

The U.S. FDA expanded the approval for use of Boston Scientific Corp.’s Watchman Flx and Watchman Flx Pro left atrial appendage closure (LAAC) devices to include post-ablation patients, bringing good news to the company as it preps for its second quarter earnings report on July 23.

Three years after the U.S. FDA approval of Abbott Laboratories’ Amplatzer Amulet, results of its investigational device exemption trial failed to notably differentiate Abbott’s left atrial appendage occluder system from Boston Scientific Corp.’s market-dominant Watchman device beyond the ability to forego anticoagulants quickly after implantation.

Conformal Medical Inc. plugged the gap in funding needed to complete enrollment in the pivotal CONFORM trial for its left atrial appendage occlusion (LAAO) technology with completion of an oversubscribed $35 million series D fundraising round. The Conformal left atrial appendage seal (CLAAS) system is designed to close off the left atrial appendage in individuals with non-valvular atrial fibrillation to cut the risk of stroke and avoid the use of anticoagulants.

The 2022 Transcatheter Cardiovascular Therapeutics annual meeting highlighted mostly positive outcomes from major trials conducted by nearly all the big players in the cardiac device market. Here’s our round-up of the meeting’s high points, with updates from Abbott Laboratories, Abiomed Inc., Boston Scientific Corp., Edwards Lifesciences Corp., Inari Medical Inc., Medtronic plc and Recor Medical Inc.
