Background: Jailed wire (JW) in the side branch (SB) is recommended during coronary bifurcation provisional stenting, but real benefit is unsure. Our objective was to evaluate benefit of a JW technique in the CABRIOLET registry.

Methods: In CABRIOLET, including 500 patients, we compared the primary composite endpoint poor final SB angiographic result (TIMI flowB, thrombosis, residual stenosis>70%, or additional SB stenting) whether JW was performed or not.

We report a case of a complex transcatheter aortic valve implantation (TAVI) complicated by severe calcifications, which prevented the delivery system from advancing through the aortic valve. To address this challenge, we employed an innovative solution using a Snare catheter. This approach enabled stabilization and guidance of the delivery system, facilitating the crossing of the calcified obstruction and the successful completion of the procedure.

Background: Spontaneous coronary artery dissection (SCAD) remains a rare form of acute coronary syndrome (ACS) in young women. It is not always easy to diagnose and its management can be complex, particularly in the case of severe forms.

Case Summary: A 29-year-old Mahorese woman presented with non-ST-elevation acute coronary syndrome 72 h after vaginal delivery of an uncomplicated twin pregnancy.

Background: Despite improvement in devices, in-stent restenosis remains a frequent and challenging complication of percutaneous coronary interventions.

Methods And Results: The RESTO (Morphological Parameters of In-Stent Restenosis Assessed and Identified by OCT [Optical Coherence Tomography]; study NCT04268875) was a prospective multicenter registry including patients presenting with coronary syndromes related to in-stent restenosis. All patients underwent preintervention OCT analysis, which led to analysis of in-stent restenosis phenotype, number of strut layers, and presence of stent underexpansion.

Iatrogenic coronary dissections are rare but potentially serious. Their management is complex, particularly if the dissection occurs without an angioplasty guide in the arterial lumen. In this context, angiography alone is insufficient, and endocoronary imaging is essential (using optical coherence or IVUS) to guide angioplasty when necessary (guide in the true lumen, coverage of the tear).
