[The potential of magnetic resonance imaging for the surveillance of septal alcohol ablation in hypertrophic obstructive cardiomyopathy. A case report]. / Potentialité de l'imagerie par résonance magnétique pour la surveillance du traitement par alcoolisation septale de la cardiopathie hypertrophique obstructive. A propos d'un cas.

We describe here the MRI surveillance of septal alcohol ablation in a case of symptomatic obstructive cardiomyopathy. MRI examinations were performed before, 15 days and 2 months after alcohol ablation using an identical protocol to study the function, regional perfusion and the equilibrium perfusion in order to directly visualize the infarction. MRI seems to be an excellent investigation in the surveillance of such patients, allowing precise quantification of the infarcted zone. The various stages of cellular necrosis in the induced infarct were demonstrated, and the role of remodelling in increasing the functional area of the systolic ejection pathway.
