Catheterization laboratory activity before and during COVID-19 spread: A comparative analysis in Piedmont, Italy, by the Italian Society of Interventional Cardiology (GISE).

Background: COronaVIrus Disease 19 (COVID-19) led to the reorganization of Cardiology Units in terms of working spaces and healthcare personnel. In this scenario, both outpatient visits and elective interventional cardiology procedures were suspended and/or postponed. We aimed to report the impact of COVID-19 on interventional coronary and structural procedures in Piedmont, Italy.

Immediate and medium-term outcomes following the treatment of very long (> or =50 mm) chronic total coronary artery occlusions.

Objective: The follow-up patency rates and associated clinical and angiographic variables following stenting of very long (> or =50 mm) and chronic (>6 months) total coronary artery occlusive lesions are not well documented. The aim of the present study was to evaluate the early results and mid-term outcomes following angioplasty of such lesions.

Methods: Between January 2000 and June 2002, we treated 278 chronic coronary occlusions.
