AI Article Synopsis
- Subvalvular aortic stenosis (SAS) is a common heart issue in dogs, but long-term success rates for surgeries to correct it have been disappointing.
- Cutting balloon valvuloplasty, a technique used in humans for similar conditions, is being investigated as a potential treatment for dogs with severe SAS.
- The report details this technique, the materials needed, and practical tips for performing the procedure safely and effectively.
Article Abstract
Subvalvular aortic stenosis (SAS) is one of the most common congenital cardiac malformations in dogs. Unfortunately, the long term success rate and survival data following either open heart surgery or catheter based intervention has been disappointing in dogs with severe subaortic stenosis. Medical therapy is currently the only standard recommended treatment option. A cutting balloon dilation catheter has been used successfully for resistant coronary artery and peripheral pulmonary arterial stenoses in humans. This catheter is unique in that it has the ability to cut, or score, the stenotic region prior to balloon dilatation of the stenosis. The use of cutting balloon valvuloplasty combined with high pressure valvuloplasty for dogs with severe subaortic stenosis has recently been reported to be a safe and feasible alternative therapeutic option. The following report describes this technique, outlines the materials required, and provides some 'tips' for successful percutaneous subaortic balloon valvuloplasty.

Introduction: Carotid artery stenosis is a significant contributor to ischemic strokes, and its surgical management includes carotid artery endarterectomy (CEA), transfemoral carotid artery stenting (TF-CAS), and trans carotid artery revascularization (TCAR). CEA has traditionally been preferred, but TF-CAS and TCAR are also excellent alternative options if the anatomy of the vessels allows them. This study reports our short- and mid-term outcomes after carotid artery revascularization in symptomatic patients at a stroke center.

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.
