Major Complications and Failure Modes of the Angiosculpt Scoring Balloon Catheter: Analysis of the MAUDE Database.

Since its Food and Drug Administration approval in January 2007, the Angiosculpt scoring balloon catheter has been widely utilized in severely calcified stenotic vascular lesions. We sought to characterize the complication rates, failure modes, and outcomes associated with the Angiosculpt catheter. Using queried events from October 2013 to December 2020 from the Food and Drug Administration Manufacturer and User Facility Device Experience database, we analyzed the Angiosculpt scoring balloon catheter complication rates and mode of failure.

Outcomes of beta blocker use in cocaine-associated chest pain: a meta-analysis.

Objectives: Beta blockers (β-blockers) remain a standard therapy in the early treatment of acute coronary syndromes. However, β-blocker therapy in patients with cocaine-associated chest pain (CACP) continues to be an area of debate due to the potential risk of unopposed α-adrenergic stimulation and coronary vasospasm. Therefore, we performed a systematic review and meta-analysis of available studies to compare outcomes of β-blocker versus no β-blocker use among patients with CACP.
