This MurmurMD case discussion features Dr. Chris Brown and Dr. Christian McNeely walking through a high-risk PCI case where the hardest part was not just the calcium, it was deciding when and how to intervene safely.
The patient was an 82-year-old frail female who presented with chest pain and NSTEMI. Angiography showed heavily calcified distal left main disease, proximal circumflex disease, a tight calcified mid-LAD, moderate LV dysfunction, and an occluded RCA. She was transferred for surgical evaluation, but then developed neurologic changes while on heparin and was found to have a small amount of bleeding in a prior meningioma resection bed.
That created a difficult clinical problem: surgery was no longer feasible, anticoagulation and antiplatelet therapy carried real neurologic risk, and the coronary anatomy still needed treatment.
The discussion focuses on practical decision-making in a case with limited bailout options: waiting for stable neuro imaging, rechallenging heparin, checking rapid CYP2C19 genotype to support a short-DAPT plan, using Impella support, planning access with CTA, modifying severe calcium with rotational atherectomy and Shockwave IVL, preserving the circumflex with a nano-crush style strategy, and carefully managing closure and anticoagulation reversal.
KEY TOPICS
• Frail elderly NSTEMI patient with severe calcified left main/LAD/circ disease
• Neurologic complication after heparin in prior meningioma resection bed
• Timing PCI after stable serial neuro imaging
• Short-DAPT planning and rapid CYP2C19 testing
• Why hemodynamic support was used
• CTA planning for calcified tortuous iliac access
