Maria Misericordia, Udine, Italy. 6 Istituto Italiano Ricerche Mediche, Verona, Italy. 7 Telethon Institute of Genetics and Medicine (TIGEM), Naples, Italy. 1 Leonardo: Results AIM: An innovative xenon-chlorine (excimer) pulsed laser catheter (ELCA X80) has been recently used for the treatment of complex coronary lesions, as calcified stenosis, chronic total occlusions and non-compliant plaques. Such complex lesions are difficult to adequately treat with balloon angioplasty and/or intracoronary stenting. The aim of this study was to examine the acute outcome of this approach on a cohort of patients with coronary lesions.

METHODS AND RESULTS: Eighty patients with 100 lesions were enrolled through four centers, and excimer laser coronary angioplasty was performed on 96 lesions (96%). Safety and effectiveness data were compared between patients treated with standard laser therapy and those treated with increased laser therapy. Laser success was obtained in 90 lesions (93.7%), procedural success was reached in 88 lesions (91.7%), and clinical success in was obtained in 87 lesions (90.6%). There was no perforation, major side branch occlusion, spasm, no-reflow phenomenon, dissection nor acute vessel closure. Increased laser parameters were used successfully for 49 resistant lesions without complications. Leonardo: Conclusion This study suggests that laser-facilitated coronary angioplasty is a simple, safe and effective device for the management of complex coronary lesions. Furthermore, higher laser energy levels delivered by this catheter improved the device performance

without increasing complications. The use of excimer laser for complex coronary artery lesions (2015) Ben-Dor I, Maluenda G, Pichard AD, Satler LF, Gallino R, Lindsay J, Waksman R. Abstract Excimer laser coronary atherectomy (ELCA) has been used for coronary intervention for more than 20 years. Advances in delivery systems for laser energy using the xenon-chlorine pulsed laser catheter deliver higher energy density with lower heat production. The Spectranetics CVX-300 (Spectranetics, Colorado Springs, CO, USA) excimer laser catheter system has been used for the treatment of complex coronary lesions. We report our experience with the use of this advanced system for stenoses for which were unsuitable for standard percutaneous coronary intervention; for example, balloon-resistant lesions, chronic total occlusions, and for underexpanded stents in calcified lesions. ELCA may also be valuable for thrombus-containing lesion.

We find ELCA to be indispensable in the catheterization laboratory for specific complex or calcified lesions. Its role should be explored in a large randomized trial of thrombus containing lesions and saphenous vein grafts. LASER NEL TRATTAMENTO DELLA RESTENOSI INTRASTENT The state of the excimer laser for coronary intervention in the drug-eluting stent era (2011) Badr S1, Ben-Dor I, Dvir D, Barbash IM, Kitabata H, Minha S, Pendyala LK, Loh JP, Torguson R, Pichard AD, Waksman R. Interventional Cardiology Unit Medstar Hospital Center Washington OBJECTIVES: This study aims to determine how excimer laser coronary atherectomy (ELCA) performs in the drug-eluting stent (DES) era.

BACKGROUND: For more than 20 years, ELCA has been used for coronary intervention. With developments in the coronary intervention field, the role of ELCA is in question. METHODS: The study includes 119 patients with 124 lesions who underwent percutaneous coronary intervention (PCI) with ELCA in our institution from January 2004 to May 2011. The state of the excimer laser for coronary intervention in the drug-eluting stent era (2011) Badr S1, Ben-Dor I, Dvir D, Barbash IM, Kitabata H, Minha S, Pendyala LK, Loh JP, Torguson R, Pichard AD, Waksman R. Interventional Cardiology Unit Medstar Hospital Center Washington RESULTS: The main indications for ELCA use were saphenous vein graft (SVG) (45

lesions), acute myocardial infarction (AMI) (7 lesions), chronic total occlusion (CTO) (32 lesions), in-stent restenosis (ISR) (15 lesions), and calcified de-novo lesions (25 lesions). High success rates were recorded for the SVG, AMI, CTO, ISR, and calcified lesion indications (91.1%, 85.7%, 93.8%, 86.7%, and 80%; respectively). ELCA related complications were reported in 10 patients (8%); four dissections, three no-reflow phenomena, two perforations, and one thrombus formation. CONCLUSION: ELCA is an alternative solution with acceptable performance in the treatment of complex coronary lesions not ideally suitable for balloon angioplasty.

PER LIMPIANTO DI STENT BIOASSORBIBILI RAFFAELLO Pilot Study 2017 Objective The objective of this Pilot Study is to suggest that Laser Angioplasty may yield better lesion preparation leading to a larger final lumen following stent implantation. These findings will be particularly relevant when applied to bioresorbable scaffold implants. Laser for complex lesion preparation Non-compliant balloons, Angiosculpt balloon, Cutting balloon and Rotational Atherectomy are the currently available devices to ensure optimal lesion preparation.

None of them with the exclusion of Rotational Atherectomy that requires a dedicated wire, have demonstrated predictable effectiveness in complex fibrocalcific lesions. Laser angioplasty with the current advanced devices has the potential to fill this gap. Inclusion criteria: Long lesions requiring stents 38 mm or longer No extreme calcifications requiring, according to the judgment of the investigator, rotational atherectomy Estimated vessel size 2.5 mm or larger Possibility to perform optical coherence (OCT) study prior to the procedure RAFFAELLO Pilot Study

Procedure: A baseline OCT exam will be performed Laser angioplasty with Spectranetics Turbo-Elite 0.9 cath. 80/80 will be performed with a minimum of 2 passes with saline flush Repeat OCT High-pressure balloon dilatation Stent or BRS implantation Postdilatation as needed Repeat final OCT The endpoint of this study will be minimal instent luminal cross sectional area. This value will be compared with matched cases performed with standard technique. We propose performing 10 Pilot cases. This study will be performed in San Raffaele by two dedicated operators dr. Antonio Colombo and dr. Azeem
