Márcio Galindo Kiuchi is a Brazilian, 36 years old doctor, master in basic sciences and a PhD in medical sciences, qualifications awarded by the Federal University of Rio de Janeiro and Fluminense Federal University, respectively. Also, he is cardiologist, this title granted by the Federal Fluminense University. He is also electrophysiologist, specialist in pacemakers, implantable cardiac defibrillators and cardiac resynchronization therapy. His doctoral thesis was on percutaneous renal sympathetic denervation
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.
