[Outpatient PCI in France: data from the France PCI registry].

Percutaneous coronary intervention (PCI) is the preferred method of revascularization for chronic coronary syndromes. Outpatient PCI has demonstrated, in addition to its reliability and safety, the comfort of patients and the reduction of costs that weigh on our healthcare systems. Nevertheless, it remains largely underutilized in France, with significant disparities between centers, particularly between private and public ones.

Optical coherence tomography to guide percutaneous coronary intervention of the left main coronary artery: the LEMON study.

Background: Intravascular ultrasound (IVUS)-guided PCI improves the prognosis of left main stem (LMS) PCI and is currently recommended by international guidelines. Although OCT resolution is greater than that of IVUS, this tool is not yet recommended in LMS angioplasty due to the absence of data.

Aims: This pilot study aimed to analyse the feasibility, safety and impact of OCT-guided LMS PCI.
