We report the ablation procedure of a concealed accessory pathway (AP) localized within a persistent left superior vena cava (PLSVC) in which the use of the LocaLisa system was of great value. The AP was the source of symptomatic AV re-entrant tachycardia and located in the initial portion of a PLSVC. The LocaLisa system allowed correct catheter placement and monitoring of stability. Five cooled-radiofrequency applications within the PLSVC suppressed the AP. PLSVC is a very unusual site of APs. The use of a navigation system may be extremely helpful in improving catheter ablation placement and stability in a very dilated vessel.
OBJECTIVES: To review the evolution and current status of probe ablative methods of minimally invasive nephron-sparing surgery (MINSS) for renal tumours. METHODS: The English language literature of the past 10 yr was reviewed by using the National Library of Medicine database and the following keywords: chemoablation, cryoablation, high-intensity focused ultrasound, kidney, laser interstitial thermotherapy, microwave thermotherapy, nephron-sparing surgery, radiofrequency ablation, radiosurgery, renal, and tumour. Over 300 papers were identified, 50 of which were selected for this review on the basis of their contribution in advancing the field with regards to (1) evolution of concepts, (2) development and refinement of techniques, and (3) intermediate- and long-term clinical outcomes. RESULTS: Open partial nephrectomy is the reference standard for nephron-sparing surgery against which all MINSS techniques should be measured. Although the initial outcomes of cryoablation and radiofrequency ablation (RFA) are encouraging, long-term studies are necessary to confirm lasting efficacy. The optimal modality for tumour targeting, monitoring therapy, and follow-up remains to be determined. These ablative techniques should be reserved for carefully selected patients, the data should be prospectively accrued, and the long-term cancer cure rates should be compared with the reference standard. CONCLUSIONS: Promising long-term data are available for cryoablation. RFA is still considered developmental, and instances of incomplete cell kill, despite nonenhancement, are concerning. Other modalities are still experimental.
