My grandfather now has titanium parts in his heart. His heart is working better than it has in years and he is feeling great. The installation of said parts was done through a small incision to access a major blood vessel, into which a tube was inserted, and the parts were moved into place via wires. After coming home, he wore a 24-hour monitor for blood pressure and heart rate. The monitor sent data to the doctor via wi-fi automatically, who would call him or notify ambulance if a concerning anomaly was detected. Getting a pacemaker is considered an outpatient procedure and you can watch videos of it on YouTube.
