Insights
Type A aortic dissection involving the left main coronary artery caused cardiogenic shock. Intravascular ultrasound guided prompt diagnosis and stenting, restoring blood flow and preventing dissection spread.
Area of Science:
- Cardiology
- Vascular Surgery
- Medical Imaging
Background:
- Type A aortic dissection (TAAD) can compromise coronary arteries, leading to acute coronary syndromes and cardiogenic shock.
- Left main coronary artery (LMCA) involvement in TAAD presents a critical challenge due to its pivotal role in supplying the left ventricle.
- Prompt diagnosis and intervention are crucial for managing life-threatening complications of LMCA dissection.
Abstract:
A 65-year-old man developed chest pain under cardiogenic shock. Coronary angiography revealed severe stenosis from the ostium of the left main coronary artery (LMCA) to the left anterior descending artery (LAD). Intravascular ultrasound (IVUS) identified a large hematoma that originated from the aorta and extended into the LAD, thereby compressing the true lumen. Type A aortic dissection (TAAD) that involved the LMCA was diagnosed by IVUS. Coronary stenting was performed via the LMCA to the proximal LAD, which resulted in coronary blood flow restoration and no further propagation of dissection. Elective surgical aortic repair was performed 2 wk after the stenting. LMCA stenting under IVUS guidance is effective for prompt diagnosis and precise stent deployment in patients with cardiogenic shock due to TAAD with LMCA dissection.
