Angioplasty and stenting have become routine practice for the treatment of significant obstructive atherosclerotic vascular disease. This method of revascularization has a longer history concerning coronary artery disease but is becoming an increasingly used modality of revascularization in the peripheral circulation. Neointimal formation is the pathological basis for restenosis after revascularization procedures such as angioplasty, stenting, and bypass grafting. While restenosis is less of a problem in the coronary circulation with the advent of drug-eluting stents, it continues to be a problem however in the peripheral arterial system. Current treatments to prevent restenosis include pharmacologic, mechanical and cellular approaches which we will discuss in this manuscript.

Background: Aortic coarctation (CoA) is a congenital anomaly leading to upper-body hypertension and lower-body hypotension. Despite surgical or interventional treatment, arterial hypertension may develop and contribute to morbidity and mortality. Conventional blood pressure (BP) measurement methods lack precision for individual diagnoses and therapeutic decisions.

Background: There is a paucity of data regarding drug-coated balloon (DCB) treatment in the context of left main (LM) true bifurcation lesions.
Aims: The aim of this study was to evaluate the safety and efficacy of DCB-based treatment for unprotected LM true bifurcation lesions.
Methods: A total of 39 patients with LM true bifurcation lesion (Medina: 1,1,1/0,1,1/1,0,1) who were successfully treated with DCB alone or in combination with drug-eluting stent (DES) were retrospectively enrolled into the DCB-based group.

We present a case of an 86-year-old female with chronic mesenteric ischemia secondary to long-segment flush occlusion of the superior mesenteric artery and near-total occlusion of the celiac artery. The superior mesenteric artery was unable to be revascularized by conventional antegrade approaches. Successful transcollateral crossing of the occluded superior mesenteric artery and body-flossing, followed by antegrade balloon angioplasty, shockwave lithotripsy, and stent implantation were performed.

Background: Bioresorbable scaffolds (BRS) were developed to overcome limitations related to late stent failures of drug-eluting stents, but lumen reductions over time after implantation of BRS have been reported. This study aimed to investigate if lesion preparation with a scoring balloon compared with a standard noncompliant balloon minimizes lumen reduction after implantation of a Magmaris BRS assessed with optical coherence tomography and intravascular ultrasound.
Methods: Eighty-two patients with stable angina were randomized in a ratio of 1:1 to lesion preparation with a scoring balloon versus a standard noncompliant balloon before implantation of a Magmaris BRS.

Percutaneous coronary interventions in highly calcified atherosclerotic lesions are challenging due to the high mechanical stiffness that significantly restricts stent expansion. Intravascular lithotripsy (IVL) is a novel vessel preparation technique with the potential to improve interventional outcomes by inducing microscopic and macroscopic cracks to enhance stent expansion. However, the exact mechanism of action for IVL is poorly understood, and it remains unclear whether the improvement in-stent expansion is caused by either the macro-cracks allowing the vessel to open or the micro-cracks altering the bulk material properties.
