Echo video 1.mp4 12.53 LAD stent thrombosis.mp4Relevant Test Results Prior to Catheterization
EKG showed normal sinus rhythm with ST segment elevation at V1-V4, Q wave in II III aVF.
Echocardiogram showed impaired LV systolic function, EF29.90% by Teichholz, 33.00 % by modified Simpson-biplane, global wall hypokinesia with anteroseptal wall hypokinesia at basal to apical LV part, Impaired RV systolic function. No significant VHD

On Lucas CPR Proceed directly to PCI of LAD,
Guiding : EBU 7/3.5 to LCA
Guide wire : Turntrac to LAD
Pre dilatation : SC balloon 2.0 x 15 inflated mLAD upto 12 atm, inserted IVUS to LAD IVUS revealed neoatherosclerotic mLAD stent, SC balloon 3.0 x 15 mm inflated mLAD upto 12 atm, Rapamycin eluting stent 3.5 x 31 mm deployed mLAD upto 12 atm with POT Puff sign. Acceptable angiographic result.
Case Summary
Key principles in cardiac arrest management during PCI: prompt recognition of the arrest rhythm, initiation of high‐quality CPR, immediate consideration for mechanical support when appropriate, and rapid revascularization.
The LUCAS device can provides consistent mechanical chest compressions and can be effectively employed for CPR in the cardiac catheterization laboratory setting.
The role of LUCAS and similar devices continues to evolve.
There is growing support for their use not only as a bridge during resuscitation but also in procedural facilitation for complex coronary interventions in patients with cardiac arrest.
Intravascular imaging is beneficialindetermining mechanism of CAD, informing therapeutic strategy and confirmingeffective treatment of PCI.
