Both heavily calcified and ostial lesions are difficult to deal with by percutaneous transluminal coronary angioplasty (PTCA) alone. Acute results are often sub-optimal, complications are more frequent, and long-term results are disappointing. Optimal stent deployment may not be possible unless satisfactory lesion dilatation is achieved and the lesion made more compliant. The use of rotational atherectomy and cutting balloon angioplasty to a calcified ostial lesion in the left circumflex coronary artery prior to stent implantation is reported.

Article Synopsis
- * A total of 454 patients were included, with more men than women, and women showed higher rates of acute coronary syndrome and aorto-ostial lesions.
- * Results indicated that despite differences in clinical presentation, the safety and efficacy outcomes of IVL were comparable between men and women, demonstrating its effectiveness across genders.

Background: Percutaneous coronary intervention of calcified aorto-ostial lesions (AOL) pose unique challenges due to anatomical propensity for recoil, leading to poorer outcomes compared to non-AOL. Although intravascular lithotripsy (IVL) has shown excellent success and safety in heavily calcified plaques, evidence specific to AOL is limited. This study aims to evaluate the efficacy and safety of IVL in AOL versus non-AOL.

Article Synopsis
- An 83-year-old woman with leg pain underwent endovascular therapy (EVT) for severe stenosis in the right superficial femoral artery (SFA) using the Jetstream™ atherectomy system and a paclitaxel-coated balloon (PCB).
- Although the initial procedure showed lumen improvement, her symptoms returned 9 months later due to the development of a pseudoaneurysm and severe stenosis.
- This case highlights the risk of pseudoaneurysm as a complication of EVT with the Jetstream™ system, despite its benefits in treating calcified arterial lesions.
Virtual Reality-Guided Simulation for Percutaneous Coronary Intervention in a Patient with Anatomical Anomalies: A Case Report.
Am J Case Rep

Department of Cardiology, Pulmonology, and Nephrology, Yamagata University School of Medicine, Yamagata, Japan.
BACKGROUND Virtual reality (VR)-guided GC simulation for patients with anatomical anomalies using cardiac computed tomography (CT) has been recently reported. Rotational atherectomy (RA) for the left circumflex (LCX) ostium is challenging due to the tortuous anatomy, acute angulation, and variable vessel size compared to other lesions. The appropriate positioning and coaxiality of the guide catheter (GC) are key factors for safely performing RA.

The advent of excimer laser coronary atherectomy (ELCA) nearly four decades ago heralded a novel way to treat complex lesions, both coronary and peripheral, which were previously untraversable and thus untreatable. These complex lesions include heavily calcified lesions, ostial lesions, bifurcation lesions, chronic total occlusions, in-stent restenosis (including stent underexpansion), and degenerative saphenous vein grafts. We discuss the technology of ELCA, its indications, applications, and complications, and suggest the "MAXCon ELCA" technique for better outcomes without increased risk.
