Stroke, Volume 56, Issue Suppl_1 , Page AWP242-AWP242, February 1, 2025. To our knowledge, no studies have directly compared the right and left TRA for carotid artery stenting (CAS). Typically, the right radial artery is used in neurointerventions. All carotid stenoses were successfully dilated.

Stroke, Volume 56, Issue Suppl_1 , Page ATP247-ATP247, February 1, 2025. Of the 32 patients, 9(28.1%) had dissection with diagnostic angiograms, 6(18.8%) endovascular thrombectomy, 15(46.9%) aneurysm treatment, and 2(6.3%) angioplasty with or without stenting. Only 4(12.5%) were treated with hyperacute stenting.

Stroke Journal

JANUARY 30, 2025

Stroke, Volume 56, Issue Suppl_1 , Page AWMP93-AWMP93, February 1, 2025. Patients were selected based on the presence of angiographically proven symptomatic carotid occlusion, adequate landing zone and concurrent impairment of cerebrovascular reserve or recurrent ischemia despite maximal medical therapy.

It is not clear by her note what she meant by this (whether or not she recognized this EKG as diagnostic of transmural ischemia, and if so, of what territory) but emergent reperfusion therapy was not pursued. The proximal and mid LAD stenoses were stented and the OM 2 was left alone. Subendocardial ischemia does not localize.

His triage EKG is shown below: There is left bundle branch block, so the EKG must be evaluated for ischemia by Smith-modified Sgarbossa criteria. There is evidence of transmural ischemia of the posterior wall as well. Leads V1 to V4 have down-up shaped T waves typical of ischemia and atypical of LBBB.

Can you localize the culprit lesion on angiogram without taking ECG findings into account?

Dr. Smith's ECG Blog

MARCH 25, 2025

There is low voltage in the precordium which always makes reading ischemia harder. In ACS, chest pain is the warning sign of ongoing ischemia. Smith : As Willy says, and as we've said many times before, morphine will resolve pain without resolving ischemia. ECG 1 What do you think? To me, this ECG is not diagnostic.

Current treatment is with anti-thrombotics and/or anticoagulation.Lesser option is to alter the flow disturbance caused by the web (surgery or stent). 2025 Jan;110(Pt A):114-122.

He eventually underwent CAG, where a circumflex occlusion was stented. This case highlights how T-waves are very important in the assessment of ischemia and dynamic changes in acute coronary syndrome. I have often seen colleagues worry about T-wave inversions as a sign of ongoing ischemia. Clin Cardiol [Internet].

At cath there was a 100% proximal LAD occlusion, which was opened and stented. In this situation, even after the ischemia is relieved and myocardial blood flow is restored myocardial contractile function remains impaired for a variable period of time (usually days to a few weeks). Transient ischemia may lead to "stunning".
