Abstract:
Patients after arterial switch operation for transposition of the great arteries are at risk for coronary artery stenosis or obstruction due to intraoperative manipulation. This case describes an infant with impaired left ventricular function 8 months after arterial switch operation. A hemodynamically significant left coronary artery stenosis was excluded by determination of coronary flow reserve using an intravascular Doppler guidewire.
