NewHeart Watanabe Institute Successfully Performs Minimally Invasive Ascending Aortic Replacement

The NewHeart Watanabe Institute in Tokyo has successfully performed an ascending aortic replacement using Minimally Invasive Cardiac Surgery (MICS) on a female patient in her 70s. Led by Dr. Toru Koakutsu, the procedure utilized a small 8cm incision, significantly smaller than the traditional 20cm sternotomy. By employing selective cerebral perfusion and mild hypothermia (32°C), the team ensured patient safety and reduced complications. The patient recovered rapidly, beginning walking exercises the next day and being discharged after 13 days.
