CATHETERIZATION & CARDIOVASCULAR INTERVENTIONS. Comparison of the ipsi‐lateral versus contra‐lateral retrograde approach of percutaneous coronary interventions in chronic total occlusions

Kambis Mashayekhi MD, Michael Behnes MD, Zivile Valuckiene MD, Leszek Bryniarski MD, Ibrahim Akin MD, Hans Neuser MD, Franz‐Josef Neumann MD, PhD, Nicolaus Reifart MD, PhD
