Why the study?
Does myocardial perfusion imaging detect apical hypertrophic cardiomyopathy missed by routine transthoracic echocardiography in patients with chest pain?
Does myocardial perfusion imaging detect apical hypertrophic cardiomyopathy missed by routine transthoracic echocardiography in patients with chest pain?
Increased apical tracer uptake on myocardial perfusion imaging can incidentally detect apical hypertrophic cardiomyopathy that was missed on routine non-contrast echocardiography.
No takes yet. Share an insight, caveat, or question.
Apical tracer uptake on SPECT may incidentally detect apical HCM missed by echocardiography; hypothesis-generating and requires prospective validation before clinical adoption.
Irwin et al. (2010) studied this question.
