"FDA Alert: Abiomed Heart Pump Recall Linked to 49 Deaths"

The FDA has issued an alert regarding the Impella heart pump, linking it to 49 deaths and numerous injuries, citing the risk of puncturing the heart's wall. Despite this, the device will remain in use. The manufacturer, Abiomed, was faulted for delayed notice of complications, and the FDA has received additional reports of heart-wall tears linked to patient deaths since the initial notice in 2021. This alert adds to concerns about the deadly side effects of cardiac devices, particularly those that take over the heart's blood-circulating function.

"MIT engineers develop biohybrid robotic replica of the heart's right chamber"

MIT engineers have developed a robotic replica of the heart's right ventricle that combines real heart tissue with synthetic, balloon-like artificial muscles. The replica can mimic the beating and blood-pumping action of live hearts, allowing scientists to study right ventricle disorders and test devices and therapies aimed at treating those disorders. The model accurately replicates the anatomy and function of the right ventricle, including its intricate valves and structures. It can be tuned to simulate healthy and diseased states, such as pulmonary hypertension and myocardial infarction, and can be used to test cardiac devices, such as mechanical valves. The researchers hope to eventually pair the replica with an artificial model of the left ventricle to create a fully tunable, artificial heart.
