Background: Catheter ablation is assuming a larger role in the management of patients with cardiac arrhythmias. Conventional fluoroscopic catheter mapping has limited spatial resolution and involves prolonged fluoroscopy. The non-fluoroscopic electroanatomic mapping technique (CARTO) has been developed to overcome these drawbacks.

Objectives: To report the early and late outcome in patients with different arrhythmias treated with radiofrequency ablation combined with the CARTO mapping and navigation system.

Methods: The study cohort comprised 125 consecutive patients with different cardiac arrhythmia referred to our center from January 1999 to July 2005 for mapping and/or ablation procedures using the CARTO system. Forty patients (32%) had previous failed conventional ablation or mapping procedures and were referred by other centers. The arrhythmia included atrial fibrillation (n=13), atrial flutter (n=38), atrial tachycardia (n=25), ventricular tachycardia (n=24), arrhythmogenic right ventricular dysplasia (n=9), and supraventricular tachycardia (n=16).

Results: During the study period, a total of 125 patients (mean age 49 ± 19 years, 59% males) underwent electrophysiological study and electroanatomic mapping of the heart chambers. Supraventricular arrhythmias were identified in 92 patients (73 %) and ventricular arrhythmias in 33 (27%). Acute and late success rates, defined as termination of the arrhythmia without anti-arrhythmic drugs, were 87% and 76% respectively. One patient (0.8%) developed a clinically significant complication.

Conclusions: The CARTO system advances our understanding of arrhythmias, and increases the safety, efficacy and efficiency of radiofrequency ablation.

Background: Sentinel lymph node mapping is the standard of care for patients with malignant melanoma and breast cancer. Recently, SLN[1] mapping was introduced to the field of gastric cancer.

Objectives: To evaluate SLN mapping in patients with gastric cancer.

Methods: In 43 patients with gastric cancer, open intraoperative subserosal dye injection in four opposing peritumoral points was used. Ten minutes following dye injection, stained LNs were located, marked and examined postoperatively from the surgical specimen.

Results: SLN mapping was performed in 43 with gastric cancer; 782 lymph nodes were harvested and evaluated. SLNs were stained in 34 of the patients (79.1%) with a mean of 2.85 SLNs per patient. The false negative rate was 20.9%, the positive predictive value 100%, the negative predictive value 78.6% and the sensitivity 86.9%.

Conclusions: SLN mapping in patients with gastric cancer is feasible and easy to perform. SLN mapping may mainly affect the extent of lymph node dissection, and to a lesser degree gastric resection. However, more data are needed.
