Aim: The aim of this study was to analyze the intermediate results of selective stenting of superficial femoral artery (SFA) lesions after a suboptimal balloon angioplasty result.
Methods: We analyzed 70 consecutive patients with claudication or critical limb ischemia due to peripheral arterial occlusive disease who underwent stent implantation of the SFA after unsuccessful balloon-angioplasty. All patients were followed-up immediately after the procedure and 3, 6 and 12 months thereafter. Restenosis was defined as an increase of peak systolic velocity-index >2 as determined by duplex sonography.
Results: Primary patency rates at 3, 6 and 12 months were 83.4%, 66.2% and 59%, respectively. Successful reinterventions were performed for 17 reobstructions, resulting in a secondary patency rate at 3, 6 and 12 months of 91%, 89.3%, and 83.8%, respectively. At 12 months 68.6% of the patients were asymptomatic, 21.6% complained of mild (Fontaine class II a), 5.9% of severe (Fontaine class II b) claudication and 2.9% were in critical limb ischemia.
Conclusions: Our data indicate that selective stenting of the SFA after suboptimal balloon angioplasty results in intermediate patency rates similar to that reported for primarily successful PTA, thereby supporting the widely accepted policy of selective stenting as a rescue procedure after unsuccessful balloon angioplasty.

Advances in chronic thromboembolic pulmonary hypertension (CTEPH) treatment have improved prognosis, shifting focus towards symptom management. This study aimed to identify factors influencing the World Health Organization functional class (WHO-FC) in CTEPH patients. The CTEPH AC registry is a prospective, multicenter database from 35 Japanese institutions, analyzing data from August 2018 to July 2023.

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.

Unlabelled: Pulmonary vein (PV) stenosis is a rare complication following PV isolation (PVI) for atrial fibrillation. Despite the benefit of early intervention, screening is not conducted, emphasizing the importance of maintaining a high index of suspicion. Standardized management approaches are unavailable for this serious complication.
