The Supera peripheral stent has been designed to resist stent fracture, which can develop from the torsion and compressive forces in the femoropopliteal artery. We report on a case of Supera peripheral stent fracture in the early period after the index procedure in a patient with femoropopliteal artery disease. An individualised approach, considering the lesion location, patient's age and exercise capacity is important for the treatment of femoropopliteal artery disease.

Endovascular treatment of femoropopliteal artery (FPA) disease with Drug-coated balloons (DCBs) may face complications such as arterial recoil, dissection, and residual stenosis. Angiography has limited accuracy for evaluating blood flow through revascularized target lesions. Thus, there is a need for post-procedure hemodynamic assessment in treated limbs.

Background: Supera interwoven nitinol stents (IWNS) and Eluvia fluoropolymer-based drug-eluting stents (DES) were designed to improve the patency of the femoropopliteal (FP) artery; however, which type of stent yields superior outcomes in calcified FP lesions remains unclear.
Aims: To compare the safety and efficacy of Supera IWNS and Eluvia DES in severely calcified FP lesions.
Methods: This study retrospectively analyzed 257 consecutive patients who underwent endovascular therapy using either IWNS (n = 123) or DES (n = 134) for FP lesions with peripheral arterial calcium scoring system (PACSS) grade 3 or 4 severe calcification between April 2018 and December 2021 at eight cardiovascular centers in Japan.

The broad spectrum of clinical manifestations caused by peripheral arterial disease [PAD] and the morphologic heterogeneity of associated atherosclerotic lesions present a considerable management challenge. Endovascular interventions are recognized an effective treatment for PAD. Within this revascularization strategy the role of atherectomy debulking modalities continue to evolve.

Background: Fractional flow reserve (FFR) can be estimated by analysis of intravascular imaging in a coronary artery; however, there are no data for estimated FFR in an extremity artery. The aim of this concept-generating study was to determine whether it is possible to estimate the value of peripheral FFR (PFFR) by intravascular ultrasound (IVUS) analysis also in femoropopliteal artery lesions.
Methods: Between April 2022 and February 2023, PFFR was measured before endovascular therapy in 31 stenotic femoropopliteal artery lesions.
