Iatrogenic left main coronary artery dissection and intramural hematoma caused by diagnostic transradial cardiac catheterization.

The growing use of the transradial approach for percutaneous coronary interventions has been shown to decrease the risk of major vascular complications.

The adjunctive use of intravascular ultrasound may assist in the accurate diagnosis and treatment process.
