Ablation of atrial tachycardia originating from the noncoronary sinus: case report and literature review.

This report describes a patient with atrial tachycardia who underwent radiofrequency catheter ablation. Two applications of radiofrequency energy were received at different sites within 1 week. Initially, right atrium mapping indicated that the earliest activation site was located at the His-bundle region (HBR).

Effect of heparin on activation of platelet function in patients during radiofrequency catheter ablation.

[Effect of radiofrequency ablation on endothelial function and platelet activation].

Objective: To investigate the effect of radiofrequency catheter ablation on endothelial function and platelet activation.

Methods: With radioimmunoassay, enzyme linked immunosorbent assay, cell labeling with monoclonal antibody and flow cytometry technique, thirty-one consecutive patients were checked for levels of plasma endothelin (ET), von willebrand's factor (vWF) and expression of platelet alpha-granule membrane glucoprotein (CD(62P)), platelet lysosome membrane glucoprotein (CD(63)) before, immediately and 47 - 115 hours after radiofrequency catheter ablation.

Results: There was no significant difference in the levels of plasma ET and vWF before and after catheter ablation; The rate of CD(62P) and CD(63) expression rate on platelets was (4.
