After open-heart surgery in 1996, Thomas Mason learned he could never undergo another open-heart procedure. In 2009, after being diagnosed with aortic stenosis, Mason knew afternoons in his workshop would be few and far between. Thankfully, he was referred to Dr. Tom Kalapura,an expert in transcatheter aortic valve replacement (TAVR), a procedure that allows replacement of heart valves without opening the chest. “I had no pain and couldn’t believe how great I felt,”Mason says. After 36 weeks in St. John Cardiac Rehab, he’s back at his workbench, wearing the smile of a man with many more years of tinkering and creating to enjoy.
