Assessment of myocardial scarring by contrast enhanced magnetic resonance imaging in a patient 11 years after percutaneous transluminal septal myocardial ablation in hypertrophic obstructive cardiomyopathy

Abstract We report on a 60 year-old male who was one of the first patients who underwent percutaneous transluminal septal myocardial ablation (PTSMA) in our institution in 1996. Contrast enhanced cardiac magnetic resonance imaging (MRI) 11 years after the PTSMA demonstrated extensive scarring, in septal and inferior segments of the left ventricle, and an excellent functional result. It has been previously demonstrated that contrast-enhanced MRI allows detailed evaluation of size and location of septal myocardial infarction induced by PTSMA, and that infarction size detected by MRI correlates well with clinical indexes of infarct size. Our case report underlines the importance of ongoing specialized care and reassessment of patients after PTSMA including continuous clinical risk assessment.
