IVUS and CTA play complementary and critical roles in elucidating procedural difficulties and assessing stent protrusion during follow-up interventions for previously stented left main coronary arteries.
Alerts to stent protrusion risks in LMCA reinterventions; case report leaves open routine imaging protocols.
Periprocedural intravascular ultrasonography guidance for left main coronary artery stenting is well established. However, the role of this tool is also important at follow-up interventions. We present a case of a patient with previous history of left main coronary artery angioplasty. During a recent attempt to treat tight stenosis in the left anterior descending coronary artery, it was not possible to advance the stent into the left main coronary artery. Intravascular ultrasonography explained the difficulties encountered.
