A "Fish" Made From Human Cardiac Cells Swims Like a Beating HeartIn a small but significant step towards creating an artificial heart, scientists at Harvard and Emory universities have developed a synthetic fish that can keep swimming like a beating heart for more than 100 days — with its tail flipping rhythmically from side to side."Our ultimate goal is to build an artificial heart to replace a malformed heart in a child," Harvard University bioengineer Kevin Kit Parker says.This “biohybrid” fish comprises the heart’s two main attributes — voluntary movement (automaticity) and messaging triggered by mechanical motion (mechanoelectrical signaling). The two sides of its fins are composed of two layers of living heart muscle cells or cardiomyocytes each.

First Surgical Implant of Total Artificial Heart in the USAA team of surgeons at Duke University Hospital has successfully implanted a new-generation commercially-available total artificial heart, the first of such achievement in the USA. The patient was a 39-year-old man who suffered a heart failure.The Aeson artificial heart was developed by French company CARMAT, who obtained FDA approval in the USA to enroll patients with end-stage biventricular heart failure for a study.  The artificial heart uses biological valves derived from bovine tissues and operates on an external power supply.CARMAT’s artificial heart is designed to provide a temporary device for patients waiting for heart transplant surgeries. “Because of the shortages of donor hearts, many patients die while waiting for a heart transplant,” said transplant surgeon Jacob Schroder, who led the implant procedure. “We are hopeful for new options to help these patients, many like [the patient] who have devastating disease and cannot otherwise be considered for a transplant.”#heart #surgery #transplant #hearttransplant #transplantsurgery #artificialheart #CARMAT
