Synergistic Coronary Artery Calcium Modification With Combined Atherectomy and Intravascular Lithotripsy.

Background: Severe coronary artery calcification (CAC) remains challenging during percutaneous coronary intervention (PCI) and often requires 1 or more advanced calcium modification tools.

Objectives: We describe the combination use of rotational (RA) or orbital atherectomy (OA), with intravascular lithotripsy (IVL), termed rotatripsy and orbital-tripsy, respectively, for modifying CAC prior to stent implantation during PCI.

Methods: We performed a retrospective analysis of patients treated with rotatripsy or orbital-tripsy at our center between July 2019 and March 2022.

Critical Left Main Coronary Stenosis After Sutureless Aortic Valve Replacement.

Our case illustrates the feasibility of high-risk PCI to salvage LMCA stenosis, possibly caused by coronary injury during direct coronary cardioplegia for a recent triple-valve operation.

Role of copeptin in dual-cardiac marker strategy for patients with chest pain presented to ED.

Objective: The objective of the study is to evaluate the role of copeptin in the diagnosis of acute coronary syndrome (ACS) and its role in dual-cardiac marker diagnostic strategy with troponin.

Design: A prospective cohort study was carried out from May 2012 to October 2012.

Setting: The study was conducted at the emergency department (ED) of a public hospital in a cluster of Hong Kong.
