F.G.

Relevant Clinical History and Physical Exam

83 yo female hypertensive, poorly controlled diabetic. 3 hours prior complained of chest pain and shortness of breath hence brought to ER, after which she had sudden cardiac arrest. ACLS done and ROSC achieved after 8 minutes. On PE pupils were isocoric & sluggishly reactive, GCS 10, fine bibasal crackles, no appreciable murmurs, apex beat at the 5th ICS, anterior axillary line. BP 90-100/60 on norepinephrine 0.3mcg/kg/min & dobutamine 5mkd. 

Relevant Test Results Prior to Catheterization

ECG 12 leads: ST segment elevation in leads aVR and V1 with diffuse ST segment depression in other leadsChest Xray: Congestion; atherosclerotic aortaHS Troponin I: 1053 pg/mL









Relevant Catheterization Findings

LM 4.5mm with 95% distal stenosis with heavy calcification at the distal LMCA extending to ostio-proximal LAD and LCx. LAD 4mm type II vessel with TIMI 2 flow. It has a diffuse long segment proximal stenosis of 70%. Ramus intermedius fair sized diffusely diseased vessel. LCx 4mm vessel with diffusely diseased proximal segment of 80%. RCA 3.5mm dominant diffusely diseased vessel with worst stenosis of 70%. It has a pre-stenotic mid segment dilatation.

Interventional Management

Procedural Step

Support: IABP left femoral arteryAccess 1: right femoral arteryGuide & guidewire: 6F, Asahi Sion to LADPredilation of proximal LAD: 2.5x15mm balloon exchanged to 2.5x8mm due to undilatable focal segment1st rotational atherectomy using 1.25mm burr with floppy wireAccess 2: right radial arteryGuide & guidewire: 6F, Asahi Sion Blue to terminal OMPredilation of LCx: 2.0x20mm balloon upsized to 2.5x6mm due to undilatable focal segment
2nd rotational atherectomy using 1.25mm burr with extra support wireIVUS run: mixed to circumferential calcified plaques from mid LAD to distal LM and mid LCx to distal LM,LAD MLA 2.76mm2,LCx MLA1.90mm2,LM MLA 2.76mm2Stent1: 2.5x28mm DES at proximal terminal OM to midLCxStent2: 2.5x24mm DES at mid to proximal LAD

Case Summary

A heavily calcified left main bifurcation and undilatable left anterior descending artery and left circumflex artery presenting as NSTEACS with cardiogenic shock is a nightmare. A rotational atherectomy of both main vessels can be done to prepare the lesion and improve the hemodynamics. Employing a DK crush technique using double guide catheter lessens the chance of wire entanglement and may improve efficiency.
