JACC: CARDIOVASCULAR INTERVENTIONS. Renal Denervation Using an Irrigated Radiofrequency Ablation Catheter for Management of Drug-Resistant Hypertension. A Demonstrated Value?

Edward D. Frohlich, MD

Ahmed et al. (1) clearly define the 3-fold purpose of their paper: 1) new therapeutic approach for renal denervation; 2) description of their irrigated radiofrequency ablation catheter technique; and 3) the indication for the use of this procedure (i.e., management of drug-resistant hypertension). Each of these highlighted points are worthy of editorial discussion. J Am Coll Cardiol Intv. 2012;5(7):766-768. doi:10.1016/j.jcin.2012.02.019.

Purpose: Balloon-occluded retrograde transvenous obliteration (BRTO) of bleeding gastric varices (GV) is well described in the literature. Using Ethanolamine oleate as the sclerosing agent in BRTO, but it is not readily available in the United States in the desired concentrations. The authors aim is to describe their initial experience with BRTO using sodium tetradecyl sulfate (STS) foam as an alternative sclerosing agent.

JOURNAL OF INTERVENTIONAL CARDIOLOGY. A Case of a Bloated Face: SVC Syndrome Relieved by an Endovascular Approach

MOLLY SZERLIP M.D., F.A.C.P., GUNDEEP SINGH M.D., ULRICH C. LUFT M.D.

Superior vena cava (SVC) syndrome, or obstruction of blood returning from the head and upper extremities, is a syndrome that is rapidly increasing in the cardiovascular patient population due to the increasing use of transvenous devices such as permanent pacemakers, implantable cardioverter defibrillators (ICDs), and indwelling venous access devices for hemodialysis.This syndrome in the past has been seen predominately in the cancer population with malignancy being the most common reason for SVC syndrome. The management of this syndrome has largely been with a medical/supportive care approach or with surgical bypass. Given the advancement in the field of endovascular interventions and the increasing expertise in performing these procedures, an endovascular approach to relieving the SVC obstruction is rapidly becoming the treatment of choice for these patients. We describe a case of a patient who had a chronic indwelling port-a-cath who developed SVC syndrome, which was treated with an endovascular approach with stenting of the SVC/brachiocephalic vein junction. (J Interven Cardiol 2012;25:78–81) You have free access to this content Journal of Interventional CardiologyVolume 25, Issue 1, Article first published online: 22 MAY 2011.

RADIOLOGY. Principles of and Advances in Percutaneous Ablation

Muneeb Ahmed, MD, Christopher L. Brace, PhD, Fred T. Lee Jr, MD and S. Nahum Goldberg, MD

Image-guided tumor ablation with both thermal and nonthermal sources has received substantial attention for the treatment of many focal malignancies. Increasing interest has been accompanied by continual advances in energy delivery, application technique, and therapeutic combinations with the intent to improve the efficacy and/or specificity of ablative therapies. This review outlines clinical percutaneous tumor ablation technology, detailing the science, devices, techniques, technical obstacles, current trends, and future goals in percutaneous tumor ablation. Methods such as chemical ablation, cryoablation, high-temperature ablation (radiofrequency, microwave, laser, and ultrasound), and irreversible electroporation will be discussed. Advances in technique will also be covered, including combination therapies, tissue property modulation, and the role of computer modeling for treatment optimization.
