This is a multi-center, investigator initiated study that will prospectively and retrospectively examine treatment strategies and outcomes of patients who underwent percutaneous coronary interventions (PCI). The goal of this multi-center, investigator initiated, registry is to collect information on treatment strategies and outcomes of consecutive patients undergoing laser-assisted PCI among various participating centers. The study is a purely observational, chart review study and involves retrieval and compiling of data based on clinically indicated procedures and follow-up clinical and procedural outcomes. The information collected will be used to determine the frequency of laser-assisted PCI performed at the participating sites and examine the procedural strategies utilized, and the procedural (both immediate and subsequent) outcomes.

Chart review and data collection of patients undergoing laser-assisted percutaneous coronary interventions
Procedural success of the PCI
Procedural success is defined as achievement of technical success with no in-hospital major adverse cardiac events (MACE). In-hospital MACE includes any of the following adverse events prior to hospital discharge: death from any cause, myocardial infarction, urgent repeat target vessel revascularization with PCI or coronary bypass surgery, tamponade requiring pericardiocentesis or surgery, or stroke.
Time frame: through hospital discharge post-PCI procedure, approximately 24 hours, but variable based on patient recovery.
Technical success of the PCI
Technical success of the PCI was defined as successful revascularization with achievement of \<30% residual diameter stenosis within the treated segment and restoration of TIMI grade 3 antegrade flow.
Time frame: through end of PCI of procedure, approximately 5 minutes after end of procedure
major adverse cardiovascular events
In-hospital major adverse cardiovascular events (MACE) include any of the following adverse events prior to hospital discharge: death from any cause, myocardial infarction, urgent repeat target vessel revascularization with PCI or coronary bypass surgery, tamponade requiring pericardiocentesis or surgery, or stroke. MACE during clinical follow-up include death, myocardial infarction, target lesion and target vessel revascularization.
Time frame: through hospital discharge post-PCI procedure,approximately 24 hours, but variable based on patient recovery.
