Determination of the Coronary Flow Reserve of the LAD in Patients with HOCM Using the Intracoronary Doppler Catheter

Abstract

So far, from the published data concerning the characteristics of coronary flow in HOCM patients, only the retrograde flow was reproducible in our patient group. However, a decrease of the coronary flow reserve compared to a healthy control group of the literature could not be observed. Nevertheless ischemia in the subordinate vessels and on the base of microcirculation cannot be excluded.

Myocardial stress perfusion magnetic resonance in children with hypertrophic cardiomyopathy

“…Theoretical issues regarding post-denervation hypersensitivity to adenosine would also be potentially reduced with regadenoson, which is a more selective agonist. Although other modalities to assess myocardial perfusion have also been used such as positron emission tomography, 14 , 15 cardiac catheterisation using intracoronary Doppler catheter, 16 and also echocardiography, 17 stress perfusion cardiac MRI is considered the test of choice in many centres at present, and it is gaining popularity for use in the paediatric population.…”
