Imagine being the first person to get a mechanical heart valve—back in 1960, that was pure sci-fi! Dr. Dwight Harken and his team literally stopped a man’s heart, swapped out a busted valve for a metal one, and hoped for the best. Against all odds, it worked, and that quiet December surgery changed medicine forever. Now, millions live thanks to that bold move. Kinda wild how some revolutions start with a single risky bet in an OR, right? #Health #BodyHealth #MedicalHistory
