Abstract

Background and aim: Magnetic resonance imaging (MRI) provides excellent anatomical coverage for local and regional indices of aortic function and structure. However, blood pressure (BP) assessments is usually necessary for the calculation of these functional MRI parameters. Unfortunately, most pressure devices are not safe in high magnetic field. The aim of our study was to evaluate the use of the new SphygmoCor XCEL device (AtCor Medical, Australia) with a 6m hose to estimate central BP.

Methods and results: A SphygmoCor XCEL device with a 2m hose and a 2nd device with a 6m hose were fitted simultaneously on both arms of 38 subjects (63% men, median age:36.8years (28.5–58.4)). After 5 minutes rest supine, BP was recorded and then cables were changed (cuffs unchanged). Brachial, central BP, augmentation pressure (AP) and augmentation index (Aix) were recorded.

Brachial SBP, DBP, PP, central SBP, DBP PP, AP and Aix from the 2m and 6m device were strongly correlated (R2=0.96, 0.91, 0.78, 0.97, 0.85, 0.95, 0,96 respectively, p<0.001 for all.). Bland Altman plots showed no statistical difference between 2 and 6m for brachial and central SBP, DBP, PP values. However there was a difference between AP and Aix recorded with 2m and 6m hose (−2.65±1.5mmHg, p=0.043 and −5.25±2.93%, p=0.038 respectively).

Conclusion: SphygmoCor Xcel device with a 6m hose, brachial and central BP shows no statistical difference with the standard 2m hose, allowing data to be collected during MRI exams. However other parameters using waveform morphology such as AP and Aix are not so reliable.
