Abstract

A closed-heart method for treating ventricular tachycardia in a myocardial infarct patient afflicted with ventricular tachy-cardia is disclosed.The method comprises, first, defining a thin layer of spared myocardial tissue positioned between the myo-cardial infarct scar tissue and the inner surface of the myocardium (the endocardium) of the patient, and then ablating the thin layer of spared myocardial tissue by a closed-heart procedure with an ablation catheter. Apparatus for carrying out the method is also disclosed. Also disclosed is a method for prognosing the likelihood of ventricular tachycardia occurring in a myocardial in-farct patient not previously diagnosed as afflicted with ventricular tachycardia. The method comprises detecting a thin layer of spared myocardial tissue positioned between the myocardial infarct scar tissue and the inner surface of the myocardium (the en-docardium) in the patient.
