ABSTRACT
Efficacy of radiofrequency ablation (RFA) of prevertebral sympathetic nodes, concern- ing the arterial pressure lowering in 36 patients, suffering hypertonic disease and coex- istent heart diseases, was analyzed. In 12 mo after RFA a systolic arterial pressure lowering at average throughout the group by (3.24 ± 1.15) kPa, or (24.3 ± 8.6) mm Hg, diastolic arterial pressure--by (1.51 ± 0.45) kPa, or (11.3 ± 3.4) mm Hg was noted. RFA of prevertebral sympathetic nodes have had promoted a stable lowering of arterial pressure in patients, suffering chronic hypersympathicotony.

The method of prediction the enability of closure atrial septal defect before operation or in pre-bypass period during the one and one-half ventricle repair of CHD with hypoplastic right ventricle was presented. The method is based on comparison of the initial blood flow on superior vena cava (SVC) and right-to-left shunt at atrial level. Defect can be closed if flow on SVC and shunt flow are approximately equal. According to prognosis in 16 of 37 patients defect was closed. After operation there were not signes congestive heart insufficiensy and cyanosis. This approach allowes to avoid reoperations at least in half of patients. If shunt flow exceeds flow on SVC, defect must be left open.
