Dr. Schaffer

"Unexpected blockage in "widow maker" and need for two bypasses plus replacement of aortic valve was present after echo test. It was explained a team of experts would work to design the necessary operation for resolution of both.

Dr. Justin Schaffer introduced himself and explained his close relationship with the doctor who was attempting to repair my valve with an intervention. Avoiding major surgery was no longer an option. He explained the extent of success of Baylor Scott and White and the major experience his surgery team had. He had been consistently successful with doing a coronary artery bypass graft (CABG) procedure.

Dr. Schaffer was clear concise and drew a diagram of the challenges are and options. The two doctors sat down, designed and debated for long hours the most efficient procedure to give me best outcome. Both doctors had confidence in their team and support staff to erase any anxiety I had. Their success rate is the best in Texas and rated no 1.

Their goal was to get me to live to 100 like my mom. At 78, this was hitting the lottery as I always expected to die young in my 60’s like my father’s lineage. 7 out of 10 died early from high triglycerides and heart failure.

I was impressed from start to finish that the care I received was beyond excellent. God brought me here to Texas, to these Doctors, to this facility, to change the course of outcomes after almost 60 years. I got the miracle I always prayed for at Baylor Scott White Heart Hospital."
