Arterial revascularization techniques. Patients with critical limb ischemia are at risk of major amputation. The latest developments in endovascular technology and techniques provide a less invasive and valuable alternative to conventional open surgery. Major improvements in angioplasty balloons and stents have been achieved in recent years. New devices such as atherectomy catheters and dedicated guidewires have been developed and are available to treat chronic-total-occlusions (CTO) of the peripheral arteries. In parallel, new techniques have been developed to achieve more complex endovascular revascularisation; these include intraluminal recanalisation, and the SAFARI technique, which is the combination of antero and retrograde approaches to treat the femoral, popliteal and pedal arteries. Currently, only limited data are available to support these last advances in the literature. The continued uptake of these new techniques in the future will be associated with shorter hospital stay and faster recovery.

Lateral costal artery as a culprit for the steal phenomenon after coronary artery bypass grafting: a case report and review of the literature.
J Cardiothorac Surg

Department of Heart Surgery, East Slovak Institute for Cardiovascular Diseases, Ondavská 8, Košice, 040 12, Slovakia.
Background: The left internal thoracic artery (LITA) has been widely accepted as the standard for revascularizing the left anterior descending artery during coronary artery bypass grafting (CABG) surgery. However, in 10-20% of cases, the LITA may lead to unsecured side branches to the chest wall, particularly the lateral costal artery (LCA), potentially resulting in postoperative chest angina.
Case Presentation: We report the case of a 58-year-old patient who experienced persistent angina eight months after having undergone coronary artery bypass grafting (CABG) due to the steal phenomenon caused by a thick lateral costal artery (LCA).
Coronary artery disease and percutaneous coronary intervention in patients with severe chronic kidney disease.

Coronary artery disease (CAD) is the leading cause of mortality among patients with chronic kidney disease (CKD), presenting unique challenges in diagnosis and management. Advanced CKD patients often present with atypical symptoms, and conventional diagnostic and interventional approaches carry risks, including contrast-induced nephropathy and the potential need for renal replacement therapy. These risks have led to the phenomenon of "renalism," where necessary procedures may be deferred due to concerns over renal injury.

Introduction And Objectives: Patients undergoing percutaneous coronary intervention in vessels with moderate-to-severe tortuosity are at higher risk of adverse outcomes, but data are scarce in the era of newer-generation stents. We compared outcomes following percutaneous coronary intervention in vessels with moderate-to-severe tortuosity using a bioresorbable-polymer sirolimus-eluting stent (BP-SES) vs a durable-polymer everolimus-eluting stent.
Methods: A total of 2350 patients from the BIOFLOW II, IV, and V randomized trials were stratified into 2 groups based on target-vessel tortuosity: none-to-mild and moderate-to-severe.
Introduction: Lung transplantation (LT) is a lifesaving procedure in patients with end stage lung failure. The prevalence of coronary artery disease (CAD) in patients with lung disease is comparably high, and coronary angiography is widely used for coronary anatomy assessment prior to LT. Detection of significant CAD usually results in revascularization to minimize post-transplant cardiovascular events.

Utilization of cangrelor following coronary artery stent placement as a bridge to cardiac surgery has been previously described in the literature. However, the use of cangrelor as bridge therapy to cardiac surgery for endovascular revascularization is lacking. We describe a case involving a 47-year-old female who developed a left lower extremity tibioperoneal trunk non-obstructing arterial dissection following extracorporeal membrane oxygenation decannulation, requiring repair with a Viabahn endoprosthesis.
