| Abstract | Significant muscular (infundibular) right ventricular outflow tract obstruction may arise spontaneously or as part of a condition, such as tetralogy of Fallot. Muscular obstruction is usually excised surgically. We describe a novel transcatheter ablation technique wherein heat is selectively applied to subpulmonary muscular obstruction, causing tissue dessication with initial oedema that may actually cause a transient increase in stenoses and gradients, followed by eventual atrophy. This technique has not been previously used, to the best of our knowledge, in this setting although it has been used for the treatment of muscular subaortic stenosis in hypertrophic obstructive cardiomyopathy. We describe its application and results in 3 Maltese patients. |
