Acute and short-term outcome of Intravascular Coronary Lithotripsy and Excimer Laser Coronary Atherectomy for Severe Stent Underexpansion: The Multicenter IVL-ELCA DRAGON Registry.

Background: Intravascular lithotripsy (IVL) and excimer laser-coronary atherectomy (ELCA) could be both used in the percutaneous treatment of coronary stent underexpansion.

Aims: To investigate the effectiveness and safety of IVL vs. ELCA for the treatment of stent underexpansion related to heavy calcifications.

Long-term outcomes of DCB and DES for the treatment of in-stent restenosis in relation to the vessel size.

Background: Percutaneous coronary intervention (PCI) with drug-coated balloons (DCB) or drug-eluting stents (DES) are well-established treatments for in-stent restenosis, however little is known about the impact of vessel size on the outcomes. The study aimed to evaluate the efficacy and safety profile of DCB versus DES in DES in-stent restenosis depending on the vessel size.

Methods: Consecutive patients with DES in-stent restenosis who underwent PCI between January 2010 and February 2018 entered the registry with a long-term follow-up.

Drug-Eluting Balloons and Drug-Eluting Stents in Diabetic Patients Undergoing Percutaneous Coronary Intervention Due to Restenosis-DM-Dragon Registry.

: The rate of in-stent restenosis (ISR) is decreasing; however, it is still a challenge for contemporary invasive cardiologists. Therapeutic methods, including drug-eluting balloons (DEBs), intravascular lithotripsy, excimer laser coronary atherectomy, and imaging-guided percutaneous coronary intervention (PCI) with drug-eluting stents (DES), have been implemented. Patients with diabetes mellitus (DM) are burdened with a higher risk of ISR than the general population.
