Superficial femoral artery (SFA) is commonly diseased in patients with symptomatic peripheral arterial disease. Endovascular treatments have been more effectively used for SFA occlusions with new techniques and devices. Retrograde popliteal access has been used as an alternative to increase the success rate of percutaneous transluminal angioplasty (PTA) of SFA after a failed antegrade attempt. Although orbital atherectomy (OA) has been used effectively to treat SFA occlusions, there are no reports of use of OA by retrograde popliteal approach.

The presence and severity of calcified coronary plaque negatively impacts angiographic and clinical outcomes following percutaneous coronary intervention (PCI). Severe coronary calcification is associated with suboptimal stent delivery, deployment, apposition and expansion which can lead to in-stent restenosis and/or thrombosis. Severe coronary calcification is associated with incremental hazard for adverse clinical events, including death, during 5-10 years following PCI despite the use of new generation drug- eluting stents.

Objectives: Endovascular therapy (EVT) for calcified nodules in patients with peripheral artery disease (PAD) remains challenging in achieving favorable outcomes. This study aims to investigate the effectiveness of orbital atherectomy (OA) for calcified nodules using an IM catheter to precisely control the device and achieve optimal engagement with the target lesion.
Methods: We performed EVT for a calcified nodule in the right common femoral artery using an OA.
New Frontiers for Orbital Atherectomy-Crossing an Uncrossable Chronic Total Occlusion.

Article Synopsis
- Managing chronic total occlusions (CTOs) in coronary artery disease is challenging, particularly when standard techniques don't work on lesions that are difficult to cross.
- A 62-year-old male patient with exertional chest pain had multiple conventional treatments fail to address a CTO in his right coronary artery, highlighting the difficulty of these types of lesions.
- The use of orbital atherectomy with the DiamondBack 360 system finally allowed successful treatment by crossing the CTO, showcasing its potential as a valuable option for complex cases where traditional methods have failed.
Comparative Efficacy and Safety of Different Balloon Angioplasty Procedures for Infrapopliteal Artery Lesions in Chronic Limb-Threatening Ischemia Patients: A Systematic Review and Network Meta-Analysis.

Background: The optimal endovascular method to treat infrapopliteal chronic limb-threatening ischemia (CLTI) remains to be determined, given the limitations of stent use in infrapopliteal artery disease. We performed a network meta-analysis (NWM) of randomized controlled trials (RCTs) to simultaneously compare the outcomes of different balloon angioplasty procedures for infrapopliteal artery lesions in CLTI patients.
Methods: We searched the Cochrane Central Register of Controlled Trials, Embase, and PubMed.

Coronary artery disease remains the leading cause of morbidity and mortality worldwide despite advancements in percutaneous coronary intervention (PCI). With an increasing ageing population, there is a significant challenge in addressing severe calcification in atherosclerotic plaque during angioplasty. This review article focuses on atherectomy strategies such as rotational atherectomy (RA), orbital atherectomy (OA) and excimer laser coronary angioplasty (ELCA) aimed at modifying calcified lesions and improving PCI outcomes.
