BACKGROUND Direct PTCA is often used in patients with acute MI. Short-term results are favorable.(More)
Despite theoretical advantages of Directional Coronary Atherectomy (DCA) vs. PTCA, the first two controlled studies comparing both methods, the Coronary Angioplasty Versus Excisional Atherectomy Trial (CAVEAT), and the Canadian Coronary Atherectomy Trial (CCAT), showed no clinical benefit of DCA, A second generation of trials, the Optimal Atherectomy(More)

Methods. Three of the authors' earlier studies are employed to illustrate the use of this conceptual lens.(More)
Trotz theoretischer Vorteile gegenüber der Ballondilatation zeigte sich im Langzeitverlauf nach direktionaler koronarer Atherektomie (DCA) bei der CAVEAT-(Coronary Angioplasty Versus Excisional Atherectomy Trial) und der CCAT-Studie (Canadian Coronary Atherectomy Trial) keine Reduktion der angiographischen Restenoserate.
