FIGURE 6.5 Pulmonary vein (PV) isolation guided by electroan-atomical mapping. A posteroanterior view of the left atrium is displayed with locations of the PVs indicated by brown tubes. Yellow tags show locations of radiofrequency lesion around the left and right PVs. (From Ref. 182, with permission.)... [Pg.110]

Using an in vivo sheep model we macroscopically evaluated the effect of vessel size on the radiofrequency lesion creation in the lung with respect to the potential for a perfusion-mediated heat-sink effect and vascular injury, with histological correlation and assessing the type and severity of complications.

Gross and histological analysis of all radiofrequency lesions was performed to determine the extent of both vascular injury and the heat sink effect and to assess for complications. [Pg.183]

Up regulation of 3H-LSD binding (i.e., an increase in the B, ) was found in the hippocampus 2 weeks after 5-HT-depleting radiofrequency heat lesions of the midbrain dorsal and median raphe nuclei (103). [Pg.80]

In follow-up to these findings with brain injury, the experiment program with LCM was expanded to next examine the use of LCM to deliver 7P-hydroxycholesterol (7P-OHC) to a radiofrequency (thermal) lesion in the rat brain. With diO-labeled LCM, it was first reaffirmed that LCM target the injury area specifically and not the adjacent normal tissue. With immuno-histochemistry and fluorescent immunochemistry, it was then demonstrated that the 7(3-0 HC, delivered in LCM, exerts an antigliosis effect in the rat brain injury model (ref 534) (see below).

Appearance of the hand after two sessions of Only Touch and three sessions of Easy TCA (for further details, see chapter 15). The flat warts have disappeared. Note that the flat wart treated with radiofrequency is still healing. The fine visible flaking all over the hand comes from an Easy TCA peel applied to even out the Only Touch and treat the subclinical lesions. [Pg.101]

Seborrheic keratoses (Figure 30.12) are very common and are found on areas of skin that have been exposed to the sun as well as unexposed areas. The lesions are always benign, but can sometimes be difficult to distinguish from malign melanomas. Beyond a certain thickness, the kera-totic layer makes them unresponsive to peels, even to phenol. They can be treated by shave excision with a snare and radiofrequency (Elhnan unit) immediately before applying... [Pg.239]

Successful AF ablation depends upon achieving lesions that are reliably transmural (135,136). Radiofrequency energy consists of alternating electrical current which can be delivered to the myocardial tissue through a transvenous electrode catheter. The tissue resistivity results in dissipation of RF energy as heat, which conducts passively to deeper tissue layers. Most tissues exposed to temperatures of 50°C or higher for more than several seconds will show irreversible coagulation necrosis and... [Pg.109]
