Abstract

Forty-five patients were included and treated with an ablation catheter with open irrigated tip. RSD was performed by a single operator following the standard technique. Patients included with CKD were on stages 2 (n=22), 3 (n=16), and 4 (n=7). Data were obtained at baseline and monthly until 6th month of follow-up. Twenty-six out of the 45 patients had LVH and nineteen did not present LVH. The LV mass index decreased from 123.70±38.44g/m2 at baseline to 106.50±31.88g/m2 at the 6th month after RSD, P<0.0001. The end-diastolic left ventricular internal dimension (LVIDd) reduced from 53.02±6.59mm at baseline to 51.11±5.85mm 6 months post procedure, P<0.0001. The left ventricular end-diastolic posterior wall thickness (PWTd) showed a reduction from 10.58±1.39mm at baseline to 9.82±1.15mm at 6th month of follow-up, P<0.0001. The end-diastolic interventricular septum thickness (IVSTd) also decreased from 10.58±1.39mm at baseline to 9.82±1.15mm 6 months post procedure, P<0.0001. The left ventricular ejection fraction (LVEF) improved from 58.90±10.48% at baseline to 62.24±10.50% at 6th month of follow-up, P<0.0001. When the ∆ between baseline and the 6th month post RSD in LVH patients and non LVH patients were compared to the same parameters no significant difference was found.
