Acute Stent Recoil

We discuss a case of acute stent recoil during ostial RCA PCI, and go over strategies to prevent and deal with stent recoil, including the "pulse post-dilation" technique and double-stenting.

We discuss a case of restenosis of an ostial RCA stent that protrudes well out into the aorta. I go over the "Double-Wire Technique" to cannulate the mouth of the protruding stent as well as tips for stenting through the side of a protruding stent.

We discuss a case of post-MI cardiogenic shock from dynamic left ventricular outflow tract obstruction (LVOTO). We discuss how to manage cardiogenic shock with dynamic LVOTO, and also review other common reasons for post-MI shock.

Nested Bifurcation Stenting of Left Main Trifurcation

Просмотров 3,2 тыс.2 месяца назад

We discuss a case of Left Main Trifurcation PCI that required the use of the "nested bifurcation PCI" technique. This is useful when only 6 French guide catheters are available. We review how nested bifurcation PCI is done and also briefly go over the literature for left main trifurcation stenting.

STEMI: Could not engage anomalous RCA!

Просмотров 4,2 тыс.3 месяца назад

We discuss a case of anomalous RCA STEMI in which it was impossible to engage the RCA with a guide catheter. We review guide catheters to use with anomalous coronary arteries, discuss wiring with diagnostic catheters, and go over techniques to exchange catheters over coronary wires.

We discuss wiring techniques for tortuous coronary arteries, and talk about the use of the Sasuke dual lumen catheter in tortuous vessels as a tool for wire re-direction and potentially for wire re-entry from a dissection plane into true lumen.

Просмотров 4,3 тыс.8 месяцев назад

We review two ominous T wave abnormalities that are important to recognize early: the de Winter T waves (STEMI-equivalent indicating acute LAD occlusion) and the better known Wellens T waves (suggesting severe LAD stenosis). We discussed diagnostic criteria and management. Chao-Wei Hwang, M.D., Ph.D. Johns Hopkins University School of Medicine Cardiac Cath Lab, Frederick Health Hospital

STEMI from SCAD

Просмотров 3,1 тыс.8 месяцев назад

We discuss a case of SCAD (spontaneous coronary artery dissection) that resulted in a STEMI. We go over PCI techniques for SCAD, which are often opposite for what we normally do for PCI. We also review the mechanism for SCAD formation as well as strategies for medical management and SCAD prevention.
