As the clinical use of cryoablation for the treatment of cancer has increased, so too has the need for knowledge on the dynamic environment within the frozen mass created by a cryoprobe. While a number of factors exist, an understanding of the iceball size, critical isotherm distribution/penetration, and the resultant lethal zone created by a cryoprobe are critical for clinical application. To this end, cryoprobe performance is typically characterized based on the iceball size and temperature penetration in phantom gel models...

Papillary muscles (PMs) were reported to be origin of ventricular arrhythmia (VA). Radiofrequency (RF) ablation was reported to be acutely effective in eliminating VA. However, the recurrence rate is high. Recently, cryoablation guided by intracardiac echocardiography, 3-dimensional mapping system, and image integration was introduced as alternative strategy for this challenging ablation. We present a case of ventricular tachycardia originating from anterior PM of left ventricle treated by cryoablation guided only by intracardiac echocardiography...

Background Image-guided thermal ablation can be used for the treatment of medically inoperable primary and metastatic lung cancer. These techniques are based on the heating up or freezing (cryoablation) of a volume of tissue around a percutaneous applicator that induces necrosis of the tumor. Method The English-language literature concerning thermal ablation of the lung was reviewed. Radiofrequency ablation (RFA) is the most widely performed and investigated of these techniques. Microwave ablation (MWA) represents a relatively new alternative that shares the same indications and is conducted in a very similar fashion as RFA...

Image-guide thermal ablations are nowadays increasingly used to provide a minimally invasive treatment to patients with renal tumours, with reported good clinical results and low complications rate. Different ablative techniques can be applied, each with some advantages and disadvantages according to the clinical situation. Moreover, percutaneous ablation of renal tumours might be complex in cases where there is limited access for image guidance or a close proximity to critical structures, which can be unintentionally injured during treatment...

OBJECTIVE: Although the Cox-maze operation is the standard surgical procedure for permanent atrial fibrillation(AF), conversion to sinus rhythm is limited by patient characteristics, including the duration of AF, atrial size, and voltage of fibrillation waves. A surgical strategy based on structural alteration of the electrical substrates of AF is required to achieve better outcomes of AF surgery. Complex fractionated atrial electrogram (CFAE) plays an important role in the electrical substrate of AF...

Balloon breach during cryoablation: To date, this is the first published report of a double-wall breach while using the cryoballoon ablation catheter during the treatment of a patient with atrial fibrillation; however, there have been previous balloon breaches in both the second and third-generation cryoballoon ablation catheter usage. In this report, we describe the case of a double-wall balloon breach and the intraoperative care that was necessary to stabilize the patient. Additionally, we review other known cases of double-wall balloon breaches, and we examine the safety systems of the cryoballoon catheter that mitigate some of the potential patient complications...

"Focal therapy/Partial Ablation" for prostate cancer now garners significant attention and controversy. Critics and skeptics point to the known multifocality nature of prostate cancer, countered by proponents of focal therapy with the "dominant index lesion versus secondary lesions" theory. Tay et al. used the C.O.L.D. Registry to retrospectively assess oncologic and functional outcomes of partial cryoablation, comparing with a propensity score-matched group who had whole gland ablation. It should be emphasized that the authors selected for partial ablation only patients with low volume, intermediate risk disease...

BACKGROUND: Cryoballoon ablation of atrial fibrillation (AF) involves successful electrical pulmonary vein isolation (PVI). Pulmonary vein (PV) ostial occlusion with cryoballoon is classically assessed using PV angiography. A pressure-guided technique to assess ostial occlusion has been evaluated in small cohorts with mixed results. We evaluated the efficacy of this pressure-guided PVI technique and its impact on reducing contrast and fluoroscopy time as compared to the traditional approach...

EDITORIAL
Antonis S Manolis
Over the recent years, the advent of single-shot techniques, such as circular catheter and cryoballoon ablation, has ushered in a new era in the catheter ablation approach and rhythm control strategies of patients with atrial fibrillation (AF). These techniques make it easier to navigate the heart and have the potential to decrease the threshold for, expand the access to, and increase patient and physician acceptance of rhythm-control therapies, that may lead to reduction of the AF disease burden and its socioeconomic impact...
