Abstract:
We report an 84-year-old patient who suddenly developed nausea, vomiting, hypotension, and needed intubation, assisted ventilation and pharmacological vasopressor support. Admission EKG showed anterior and lateral leads ST segment depression and 2 mm ST segment elevation in avR lead. Angiogram showed unprotected left-main coronary-artery (LM) sub-occlusive disease and totally occluded ostial right-coronary-artery (RCA), distally filled through the left-coronary system. Unprotected LM disease was immediately treated with bare metal stent. The stent jailed the left-circunflex coronary-artery (LCx) ostium but did not compromise the arterial flow. Lately, the patient was discharged in a very good health condition. Ten months angiographic follow-up showed an extremely compromised LCx ostium treated successfully with drug eluted stent (DES) and mid left anterior descendent (LAD) severe lesion, treated with DES.
