Catheter ablation is a major treatment for atrial tachycardias. Hereby, the precise monitoring of the lesion formation is an important success factor. This book presents computational, wet-lab, and clinical studies with the aim of evaluating the signal characteristics of the intracardiac electrograms (IEGMs) recorded around ablation lesions from different perspectives. The detailed analysis of the IEGMs can optimize the description of durable and complex lesions during the ablation procedure.

Focal Liver Lesions

Few fields of medicine have witnessed such impressive progress as the diagnosis and treatment of liver tumors. Advances in imaging technology, the development of novel contrast agents, and the introduction of optimized scanning protocols have greatly facilitated the non-invasive detection and characterization of focal liver lesions. Furthermore, image-guided techniques for percutaneous tumor ablation have become an accepted alternative treatment for patients with inoperable liver cancer. This book provides a comprehensive and up-to-date overview of the role of diagnostic and interventional radiology in respect of liver tumors. The volume moves from background sections on methodology and segmental liver anatomy to the main sections on the diagnosis of benign and malignant liver lesions. An integrated approach, focused on the correlation of ultrasound, CT, and MR imaging findings, is presented. Finally, a full section describes the principles, methods, and results of percutaneous tumor ablation techniques.

PDT versus APC in Barrett's Esophagus
56,50 € *
ggf. zzgl. Versand

The aim of endoscopic ablation in the lower third of the esophagus is to eliminate the intestinal metaplasia and hence the risk of developing adenocarcinoma. Different methods have been advocated but, to date, none of them has been shown to be the standard. We used different methods according to individualized selection criteria. We support the use of PDT for patients with grade-4 IPN. Supplementary methods for the rest of Barrett are of particular value. EMR is suitable for elevated lesion with suspicion of IPN, as it provides considerable material for exact histopathological examination. APC is needed for the elimination of the residual islands of Barrett's epithelium. APC alone could be enough for grade-3 IPN within Barrett's muosa less than 5 cm in length, as it showed esophageal stricture when used for longer lesions. Endoscopic ablation therapy is highly effective in eradicating intraepithelial neoplasia (IPN) within Barrett's esophagus. The success in totally eradicating the metaplastic epithelium was much lower. Long-term follow-up is inevitable to prove the effectiveness of ablation therapy in reducing the incidence of adenocarcinoma of the esophagus.

Progress in Catheter Ablation

Catheter ablation is widely accepted as an effective and safe form of therapy for cardiac arrhythmia. In many instances this curative procedure is considered as the first line of therapy if not the ultimate treatment of choice. With the use of radiofrequency (RF) modality, which has revolutionized the technology from a barotraumatic, potentially injurious procedure using high voltage, direct-current (DC) shock to a safe and relatively painless one, catheter ablation procedure now carries a very low risk and is extremely effective for certain types of arrhythmia. Its efficacy rate in curing supraventricular tachycardia involving an accessory pathway or dual atrioventricular nodal pathways has been near perfect and its application for certain types of atrial and ventricular arrhythmia have also been very satisfactory. However, conventional RF ablation has several well known limitations, most notably is its ability to only produce relatively small, point lesions, rendering it effective only for an arrhythmia with a small and/or a superficial target. It was soon recognized that the technology would not likely to have significant utility in arrhythmia with a more widespread target such as atrial fibrillation or those which involve scarred and deep myocardial tissue such as ventricular tachycardia. Indeed, the application of conventional RF technology in these complex but common arrhythmia has yielded unsatisfactory results.

Recurrence of Hepatocellular Carcinoma After Ra...

Hepatocellular carcinoma is a major health problem worldwide, with an estimated incidence ranging between 500,000 and 1,000,000 new cases annually. It is the fifth most common cancer in the world and the third most common cause of cancer-related deaths.For years, partial hepatectomy and liver transplantation have been considered as the main curative treatments. However, only 10% to 20% of HCC are resectable. Anatomic location, size or number of lesions, inadequate liver remnant, or co-morbid condition precludes surgery in the majority of patients. Currently, local ablative therapy competes with partial hepatectomy and liver transplantation as primary treatment for small HCC.Radiofrequency ablation (RFA) is considered a promising alternative to surgery. For irresectable tumors, RFA seems to be the most effective treatment among other locoregional therapies. The main advantages of RFA include low morbidity and mortality rates, effective tumor ablation and preservation of maximal normal liver parenchyma.However, despite the high complete necrosis rate of RFA, early tumor recurrence within one year, either local tumor recurrence or new tumor formation,remains a significant problem.
