title: Right coronary arteriography: experience with standard-torque and limited-torque techniques in children and young adults.
abstract: Coronary spasm and intimal injury may occur during selective right coronary arteriography. The safety and efficacy of right coronary arteriography in children and young adults were retrospectively reviewed for this report. Right coronary arteriography was performed in 200 patients. A standard-torque technique was used in 150 patients, a limited-torque technique was used with a reshaped left coronary catheter in 53 patients. The standard-torque technique was associated with proximal coronary spasm in nine patients, nonsustained ventricular tachycardia in one patient, and ST segment changes in one patient. The limited-torque technique was associated with no complications. The standard-torque technique was effective in one patient when the limited-torque technique failed to define distal coronary branches clearly. The limited-torque technique was effective in nine patients when the right coronary artery could not be engaged while attempting the standard-torque technique. In conclusion, right coronary arteriography may be performed in a safe and potentially more effective manner using a new catheter design and a limited-torque technique.
