New LAA occluder technology and the debate on echo vs. CT image guidance

View of an Amulet left atrial appendage (LAA) occluder on 4D intra-cardiac echo (ICE) from a GE NuVision ICE catheter. Since ICE is operated by the interventionalist, it can be used to reduce the number of people needed to perform an LAA occlusion procedure.

At TVT 2022, there was debate whether CT imaging is needed for preplanning LAA procedures, and several new devices in development were discussed.

FDA may allow clinical trials of pig organ transplants into human patients

The most successful case to date of a pig organ being transplanted into a human occurred back in January, when specialists at the University of Maryland Medical Center (UMMC) in Baltimore transplanted a modified pig heart into 57-year-old David Bennett. The FDA approved the heart transplant transplant through an emergency authorization typically reserved for experimental procedures seen as a patient’s last chance at survival. Bennett did die of heart failure two months later.#pigheart

The FDA would approve trials on a case-by-case basis, according to an anonymous source close to the situation.
