STEMI Disaster: Stent malfunction, LAD Dissection, and Stent Loss
A routine STEMI turned bad quickly when the stent balloon ruptured and the partially expanded stent was dragged out of the LAD. There was a large LAD dissection and eventually LAD shutdown. We discuss the case and how we used the "STAR technique" (sub-intimal tracking and re-entry) from CTO PCI as a bail-out.

PCI for STEMI + refractory VF with LUCAS CPR
Переглядів 1,5 тис.День тому
A young man presented with STEMI after shoveling snow. He arrested in the hallway on the way to the Cath Lab, and had refractory VF. We performed multi-vessel PCI of the LAD and RCA with the patient in nearly continuous VF supported by the LUCAS mechanical CPR device.

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.

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.

    Erratum: In "Step 9" / Slide 20 / 14:40 mark, re-wiring the side branch again should be through 2 stent layers, not 3.

    One of our astute viewers thought that the IVUS image actually showed that the IVUS catheter was in false lumen, and that the true lumen was to the right of the dissection flap. I thought we were true lumen throughout, but I must admit that sometimes I still have trouble telling things apart. Color doppler might have helped. In this case, we principally wanted to make sure that we ended in true lumen. This was clear in the full IVUS run (which I don't show). Fortunately for us, there are no branches to worry about in the LIMA, so it's less critical if part of the stent was in false lumen as long as the ends are in true lumen.... What I am sure of is this: The more I do this, the more I realize how much I still have yet to learn.
