Myocardial blood flow quantification in patients with an implanted cardiodefibrillator during stress and at rest using a wideband perfusion pulse sequence: an initial feasibility study.

ABSTRACT:

Background

Although a recently developed wideband perfusion sequence has shown diagnostically acceptable image quality and accurate myocardial blood flow (MBF) quantification at rest in patients with cardiac implanted electronic devices, its performance during vasodilator stress remains unproven. This study aims to determine whether the sequence produces diagnostically acceptable image quality during stress and is capable of quantitatively detecting abnormal stress MBF and myocardial perfusion reserve (MPR) in patients with implanted cardiodefibrillators (ICDs).

Methods

We enrolled 29 patients with an ICD (mean age=63±15years, 17 males, 12 females) and 11 control patients (mean age=50±17years, 6 males, 5 females; negative coronary artery disease; negative stress perfusion CM
