Unravelling the puzzle of antithrombotic therapies for complex percutaneous coronary intervention.

Percutaneous coronary intervention (PCI) has remarkably evolved in the last decades. This has resulted in a larger number of patients treated with PCI, including those with more complex anatomic lesions. Several studies demonstrated that PCI involving complex lesions is associated with increased rate of procedural complications and adverse clinical outcomes. In this setting, optimal adjunctive antithrombotic regimens still need to be defined. In this review, we sought to summarize and discuss the recent evidence deriving from analyses appraising antithrombotic therapies in patients undergoing complex PCI.
