Atrioventricular (AV) node ablation represents an established therapeutic option in the management of atrial fibrillation (AF) and other atrial tachyarrhythmias, particularly in patients with symptomatic tachycardia who remain unresponsive or intolerant to pharmacological therapy. The procedure is often considered in…

Atrioventricular nodal re-entrant tachycardia (AVNRT) occurs in patients with dual AV nodal physiology. They have two functionally distinct pathways known as the slow and fast pathway. The slow pathway has a shorter refractory period. During the common form of AVNRT, an atrial premature beat travels down the slow…

'Weilin Wang'] BACKGROUND & AIMS Metastasis in retroperitoneal lymph nodes is one of the signs of advanced stage or terminal stage of malignancy. We performed a trial to assess the safety and efficacy of ultrasonography (US)-guided local neodymium-doped yttrium aluminum garnet (Nd:YAG) laser ablation for metastatic…

The atrioventricular node (AVN) is considered a “black box”, and the functioning of its dual pathways remains controversial and not fully understood. In contrast to numerous clinical studies, there are only a few mathematical models of the node. In this paper, we present a compact, computationally lightweight…

In this case, focal PFA was used to modify the sinus node near the phrenic nerve safely, achieving acute procedural success without phrenic nerve injury; however, symptom recurrence was observed a few months after the procedure. Several factors contribute to the challenges and lower success rates of endocardial…

Pulsed field ablation (PFA) has emerged as a non-thermal alternative to traditional thermal ablation techniques for the treatment of atrial fibrillation (AF). This study presents a patient-specific 3D computational framework to model the effects of PFA on pulmonary vein isolation (PVI). The modeling framework is…

The field of oncology has witnessed remarkable progress with the integration of high-tech innovations in tumor ablation. Tumor ablation therapies, such as radiofrequency ablation (RFA), microwave ablation (MWA), cryoablation (Cryo), irreversible electroporation (IRE), and electrochemotherapy (ECT) have evolved beyond…

Atrial fibrillation (AF) is a significant burden worldwide, and the existing treatments leave much to be desired. There are, however, opportunities to improve the safety and efficacy of the most popular treatment, radiofrequency (RF) cardiac ablation, using conductive hydrogels as an ablation mediator. Lesions were…

Outcome of persistent atrial fibrillation (AF) ablation remains suboptimal. Techniques employed to reduce arrhythmia recurrence rate are more likely to be embraced if cost-effectiveness can be demonstrated. A single-centre observational study assessed whether use of general anaesthesia (GA) in persistent AF ablation…

Results: It performs better than a literature method concerning the theoretical characteristic of monotonic convergence of the bioheat PDE and a in vitro gold standard with significant improvements (p < 0.05) in terms of Pearson correlations. It shows no failure modes or theoretically inconsistent individual simulation…

Focal tumor ablation with ethanol could provide benefits in low-resource settings because of its low overall cost, minimal imaging technology requirements, and acceptable clinical outcomes. Unfortunately, ethanol ablation is not commonly utilized because of a lack of predictability of the ablation zone, caused by…

We investigate the non-thermal material dynamics of strongly excited silicon during ultra-fast laser ablation. In contrast to metals, silicon shows strongly excitation-dependent interatomic bonding strengths, which gives rise to a number of unique material dynamics like non-thermal melting, Coulomb explosions and…

Microwave ablation is a therapeutic procedure to eliminate abnormal tissue within a body selectively. There are two types of ablations; the thermal one aims to raise the temperature at the target, while the non-thermal one induces a temporarily high electric field at the target to disrupt cellular membrane integrity.…

The modification of polymer surfaces using laser light is important for many applications in the nano-, bio- and chemical sciences. Such capabilities have supported advances in biomedical devices, electronics, information storage, microfluidics, and other functional material applications. In most cases, these…

The primary objective of our study was to investigate the efficiency of high intensity focused ultrasound (HIFU) ablation in two distinct cellular configurations, 2D monolayers and 3D spheroids of epithelial breast cancer cell lines. The study also compares empirical findings from experiments with results obtained…

- Current interstitial techniques of tumor ablation face challenges that ultrasound technologies could meet. The ablation radius and directionality of the ultrasound beam could improve the efficiency and precision. Here, a 9 gauge MR-compatible dual-mode ultrasound catheter prototype was experimentally evaluated for…

Polymer flows through pores, nozzles and other small channels govern engineered and naturally occurring dynamics in many processes, from 3D printing to oil recovery in the earth's subsurface to a wide variety of biological flows. The crosslinking of polymers can change their material properties dramatically, and it is…

Graph Neural Networks (GNNs) have emerged as a powerful tool in predicting molecular properties based on structural data. While GNNs excel in identifying local patterns within molecules, their ability to capture global properties remains limited due to inherent structural challenges such as oversmoothing and their…
