To evaluate the safety and efficacy of cutting balloon angioplasty, we reviewed the early angiographic and clinical outcomes of 160 consecutive patients with 173 lesions undergoing this procedure. Angiographic core laboratory analysis was available in 150 of these lesions. Eccentricity was the most common (49%) unfavorable pre-procedural morphologic feature; other morphologic findings included length ³ 10 mm (28%), calcification (23%), angulation ³ 45 degrees (13%), irregularity (7%), ostial location (3%), and thrombus (1%). ÒStand-aloneÓ cutting balloon angioplasty was performed in 106 (71%) lesions and an adjunct balloon or new device was used in 44 (29%) lesions to treat a residual stenosis > 40% after cutting balloon angioplasty. The reference artery size was 2.80 +/- 0.42 mm. The minimal lumen diameter increased from 1.02 +/- 0.30 mm to 2.01 +/- 0.42 mm (p < 0.001) and the % diameter stenosis was reduced from 64 +/- 9% to 29 +/- 12% (p < 0.001). Angiographic success (< 50% diameter stenosis ) was obtained in 145 (97%) lesions. The residual stenosis was higher in lesions treated with stand-alone cutting balloon angioplasty than in those undergoing adjunct balloon or new device angioplasty (31 +/- 10 versus 24 +/- 14; p = 0.0006). The average cutting balloon:artery ratios in those lesions with and without dissections after cutting balloon use (1.00 +/- 0.11 versus 0.97 +/- 0.13, respectively; p = 0.29). A significant inverse relationship between the cutting balloon:artery ratio and the final % diameter stenosis was noted (R = 0.33; p = 0.0003). There were no major in-hospital complications after cutting balloon use. This series demonstrates the safety and efficacy of cutting balloon angioplasty as an alternative to conventional balloon angioplasty in patients with non complex coronary artery disease. A multicenter, randomized comparison of cutting balloon angioplasty with conventional balloon angioplasty for prevention of restenosis is currently underway.

Background/aims: Radial incision and cutting (RIC) is an alternative dilation method for stenosis of the lower gastrointestinal tract. However, its safety and efficacy for the small intestine requiring balloon-assisted enteroscopy (BAE) remain limited. Therefore, this pilot study aimed to evaluate the safety and efficacy of RIC using BAE.

Anastomotic stricture can severely compromise patients' quality of life by leading to difficulties in food intake. Although endoscopic balloon dilation has become a standard treatment for gastrointestinal strictures, its efficacy is often limited due to the risk of perforation and the potential for recurrent stricture, necessitating multiple interventions.

Objectives: The Wolverine cutting balloon (CB) (Boston Scientific) is a specialized balloon catheter with microsurgical blades that is used for balloon-resistant lesions. The Manufacturer and User Facility Device Experience (MAUDE) database serves as a repository for reports of medical device complications. The aim of this study was to analyze complications associated with CB use during percutaneous coronary intervention in real-world contemporary practice.

Coronary calcification is a major factor leading to stent under-expansion, and subsequent adverse events. This meta-analysis aimed to evaluate the short and long‑term outcomes of rotational atherectomy (RA), followed by modified balloon (cutting or scoring) (MB) versus plain balloon before drug‑eluting stent implantation for calcified coronary lesions. We searched PubMed, Web of Science (WOS), Scopus, and the Cochrane Library Central Register of Controlled Trials (CENTRAL), from inception until 30 January 2024.
