Cardiovascular Journal of Africa: Vol 33 No 3 (MAY/JUNE 2022)

CARDIOVASCULAR JOURNAL OF AFRICA • Volume 33, No 3, May/June 2022 AFRICA 161 LAD recanalisation was surprisingly difficult, highlighting the severity of the coronary artery disease in this young patient. The LAD recanalisation might be considered a CTO-like procedure, since it necessitated utilisation of a microcatheter and guidewire escalation to cross the occlusion. We ended up with a provisional stenting technique, as recommended by the current European Bifurcation Club.12 Provisional stenting reduces complication rates driven by multi-stenting strategies13 and offers additional ‘bailout’ side-branch stenting if good results are not achieved (> 70% stenosis, TIMI flow < III or dissection > B).14 Conclusion Cardiogenic shock is a major complication of myocardial infarction, particularly in young adults, if not addressed early. Prompt management with rapid diagnosis and revascularisation may help to prevent it and to improve outcomes. However, absolute smoking cessation as well as the avoidance of illicit drug use may be the best prevention in this group of young people. References 1. World Health Organization.
