"My interventional cardiologist is different
from the ones you are talking about. He uses the latest thing."
Well, in a series of randomized trials the latest things which
included: Covered stent grafts had a worse outcome in native vessels,
saphenous vein grafts, and perforated coronaries. Beta-radiation
therapy for treatment of in-stent restenosis, debulking prior
to beta-radiation, cutting balloons, X-Sizer, Heparin eluting
stents, low pressure stents, Intravascular low power laser photostimulation,
and Excimer laser coronary angioplasty (ELCA) all had either no
advantage or worse outcomes. Many of the worse outcomes were things
like death. New, new is not always better.
New Therapy of the Day
In native vessels? Worse outcome
In saphenous vein grafts? Worse outcome
In coronaries that you punctured with the PCI wire?
Bad problem, which you can salvage, if they dont die.
