A commentary on “Operator and institutional experience reduces room-to-balloon times for transradial primary percutaneous coronary intervention,” by Barringhaus, et al.
We highlight the diagnostic dilemma and therapeutic challenges encountered in a patient presenting to the emergency room with chest pain when coronary artery disease coexisted with takotsubo cardiomyopathy.
We report on the usefulness of the bidirectional kissing-balloon technique for a retrograde approach to chronically totally occluded coronary arterial bifurcation lesions.
Increased level of serum catecholamines in the acute phase was reported to be a feature of takotsubo cardiomyopathy (TC). We report a TC case with pheochromocytoma, which caused a stir in the diagnosis of TC and suggests the importance of screening f…
Fractional flow reserve (FFR)-based coronary interventions of intermediate-severity lesions are safe, cost effective, and have prognostic importance. Well-developed collateral circulation might result in overestimation of the FFR value in the donor a…
Kissing-balloon inflation is sometimes technically challenging due to inability to deliver the side-branch balloon across the structure of the main vessel stent(s). We describe an improved in-stent anchoring technique to facilitate balloon delivery t…
The inability to reposition or retrieve balloon-expandable transcatheter aortic valves once they have been deployed requires implantation of the valve in the descending aorta or open surgical procedures to extract the valve. We describe the challengi…
The use of adjunctive thrombectomy during primary percutaneous coronary intervention has steadily increased with recent trials demonstrating an improved clinical and mortality benefit for manual aspiration thrombectomy. The use of an in-dwelling guid…
A single-center retrospective evaluation of embolic reduction strategies concurrent to infrainguinal atherectomy intervention. An embolic reduction strategy using the Proteus catheter alone, particularly when Proteus and lesion lengths meet, or with…
Both diabetes mellitus (DM) and coronary artery spasm (CAS) are associated with endothelial dysfunction; thus, a higher incidence of CAS is expected in diabetic patients. We evaluated the impacts of DM and the status of blood sugar control on CAS wit…
