Key result

Intravascular ultrasound imaging successfully guided the diagnosis of catastrophic catheter-induced right coronary artery vasospasm, which was promptly reversed by intracoronary isosorbide dinitrate.

Overview

IVUS may aid diagnosis of catheter-induced coronary spasm in ambiguous cases; leaves open need for prospective validation before routine use.

Structured PICO

P
Population
A 46-year-old man with stable angina who developed severe catheter-induced right coronary artery vasospasm leading to cardiogenic shock during angiography, followed for 6 months.
I
Intervention
Intravascular ultrasound (IVUS) imaging guidance followed by intracoronary administration of 1 mg isosorbide dinitrate.
O
Outcome
Restoration of coronary flow and hemodynamic status.

IVUS imaging is a valuable tool for diagnosing catheter-induced coronary vasospasm and guiding appropriate vasodilator therapy to avoid unnecessary stenting.

Limitations

  • Single case report

Kodaira et al. (2017) conducted a case report in Catheter-induced coronary artery vasospasm (n=1). Intravascular ultrasound (IVUS) guidance and intracoronary isosorbide dinitrate was evaluated on Restoration of coronary flow. Intravascular ultrasound imaging successfully guided the diagnosis of catastrophic catheter-induced right coronary artery vasospasm, which was promptly reversed by intracoronary isosorbide dinitrate.
