Abstract/OtherAbstract:
|
Programmed electrical stimulation (PES) was performed in 17 patients, mean age 31 +/- 8 years, with minor forms of right ventricular dysplasia diagnosed because of (1) premature ventricular beats (PVBs) of left bundle branch block (LBBB) morphology; (2) no clinical or non-invasive evidence of cardiac abnormalities; (3) angiographic evidence of right ventricular wall motion abnormalities and bioptic findings of fibro-adipose infiltration. Fifteen patients had frequent and complex PVBs while two had sustained ventricular tachycardia (VT). During PES, sustained VT was induced in 2/2 patients with spontaneous sustained VT; ventricular repetitive responses were induced in 2/15 cases (13%) with complex and frequent PVBs. In conclusion, in minor forms of right ventricular dysplasia, PES induces VT only in patients with clinical VT; on the contrary, in patients with PVBs it is only possible to induce repetitive ventricular responses in a small proportion of cases; it is therefore not possible to select patients at high risk of developing severe ventricular arrhythmias. |
