Investigation of balloon dilation devices for treatment of Eustachian tube dysfunction

Current Directions in Biomedical Engineering, 2018
The presented three different balloon dilation devices for treating Eustachian tube dysfunction were compared regarding their geometries and designs. The balloon dilation behaviour was investigated by an in vitro test setup consisting of a test chamber ...

When Subtle Guiding Catheter‐Induced Stent Deformation Leads to Abluminal Guidewire Passage: Successful IVUS Tip‐Detection‐Guided Bailout

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Incomplete stent apposition at the proximal coronary artery may predispose to subtle guiding catheter–induced stent deformation, creating a gap between the stent and the vessel wall that facilitates inadvertent abluminal guidewire passage. We report a case in which balloon dilatation over an unrecognized abluminal guidewire resulted in severe ...

Paclitaxel-coated balloon dilation for central airway obstruction

Respiratory Medicine Case Reports, 2018
Introduction: Central airway obstruction (CAO) often requires repeated interventional procedures which offer variable efficacy, a time-limited effect, and have inherent limitations. Paclitaxel has been used to prevent restenosis in blood vessels.

Mechanisms and Management of Acquired Aseptic Intracardiac Communications After Transcatheter Aortic Valve Implantation: Single‐Center Case Series Insights

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Acquired aseptic intracardiac communications (AICCs) are rare but clinically relevant structural complications following transcatheter aortic valve implantation (TAVI), typically resulting from mechanical injury to the aortic annulus, interventricular septum, or adjacent structures.

In-Office Balloon Dilation for Idiopathic Subglottic Stenosis: A Pilot Study

Journal of Otolaryngology - Head and Neck Surgery
Importance Idiopathic subglottic stenosis is a debilitating and recurrent disease, often requiring reintervention. Balloon dilation is a well-recognized, minimally invasive treatment to alleviate symptoms, and is typically performed in the operating room.

Case report: Combination technique of balloon dilation, membrane excision, and topical mitomycin C for the treatment of nasopharyngeal stenosis in a cat

Frontiers in Veterinary Science
A two-year-old neutered male Turkish Angora cat presented with respiratory signs, including chronic snoring sounds and dyspnea with open-mouth breathing. Nasopharyngeal stenosis (NPS) was diagnosed based on endoscopy and computed tomography (CT).

Intravascular Lithotripsy in Left Main Stem Percutaneous Coronary Intervention

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background IVL is increasingly used for coronary calcium modification; however, prospective data for its use in LMS lesions are lacking. Aims To evaluate the feasibility, safety, and mechanical efficacy of intravascular lithotripsy (IVL) for calcium modification in calcified distal left main stem (LMS) percutaneous coronary intervention ...

Optimal dilation duration of 10 mm diameter balloons after limited endoscopic sphincterotomy for common bile duct stones: a randomized controlled trial

Scientific Reports
Limited endoscopic sphincterotomy (EST) combined with endoscopic papillary balloon dilation (EPBD) is widely used. However, the optimal duration of small balloon dilation in choledocholithiasis remains controversial.

A contemporary simple risk score for prediction of severe acute kidney injury after heart transplantation

ESC Heart Failure, Volume 12, Issue 2, Page 1166-1175, April 2025.
A contemporary simple risk score for prediction of severe AKI after HT. Abstract Background The aim of this study was to develop a simple risk score to estimate severe acute kidney injury (AKI) risk based on a large contemporary heart transplantation (HT) cohort.
