  reviewOpen accessSenior authorCorresponding

  The central anatomical locus in the context of atrial fibrillation (AF) ablation has been the pulmonary veins. Despite the attainment of a modest long-term success rate through pulmonary vein isolation (PVI), the pursuit of achieving a therapeutic efficacy nearing a definitive cure has spurred an investigation into alternative strategies and anatomical loci beyond the pulmonary veins. Despite extensive exploration, none of these alternative targets have succeeded in establishing themselves as routine ablation sites comparable to the pulmonary veins. Consequently, there exists an imperative for further inquiry and refinement of ablation strategies to propel advancements within the domain of AF ablation, thereby augmenting patient outcomes. Simultaneously, the examination of the autonomic system's role in AF pathophysiology introduces an additional ablation target aimed at rectifying sympathovagal imbalance. This discourse presents a contemporary review of renal denervation (RDN) as an emergent and auspicious technique poised to complement PVI, thereby contributing substantively to the augmentation of long-term success within the ambit of AF rhythm-control strategies.

• Differences in lower extremity kinematics during single-leg lateral drop landing of healthy individuals, injured but asymptomatic patients, and patients with chronic ankle instability- a cross-sectional observational study

  PLoS ONE · 2024-03-21 · 4 citations

  articleOpen accessCorresponding

  The lower-extremity kinematics associated with forward jump landing after an ankle injury is known to differ for patients with Chronic Ankle Instability (CAI), copers (injured but asymptomatic patients), and healthy individuals. However, the differences in the lower extremity kinematics of these groups associated with a Single-leg Lateral Drop Landing (SLDL) are unknown. The purpose of this study is to characterize the lower limb and foot kinematics during SLDL in CAI patients and to compare these characteristics with those of the copers and healthy individuals. This was a cross-sectional observational study. Nineteen participants, each, were selected from the CAI, Coper, and control groups. The lower-extremity kinematics during SLDL was measured using three-dimensional motion analysis over an interval progressing from 200 ms before landing to 200 ms after landing. Either one-way ANOVA or the Kruskal-Wallis test was used to compare the attributes of the respective groups, with each parameter measured every 10 ms. The maximum values and excursions of the parameters were established over time intervals progressing from 200 ms before landing to 200 ms after landing. Significant observations were subjected to post hoc analysis. Compared to the Coper group, the CAI group exhibited significantly smaller hip adduction angles at 160 ms, ankle dorsiflexion angles in the 110-150 ms interval, and maximum ankle dorsiflexion angles after landing. Compared to the control group, the CAI group exhibited significantly smaller excursions of MH inversion/eversion after landing. Our findings confirm the necessity of focusing on the kinematics of hip adduction/abduction and plantar/dorsiflexion during SLDL in evaluating patients with ankle injuries.

• Differences in Diaphragmatic and Chest Wall Excursion During Quiet Breathing According to Body Position: Dynamic Analysis by MRI

  Cardiopulmonary Physical Therapy Journal · 2024-10-01 · 1 citations

  article

  Background and Purpose: The diaphragm is the largest contributor to respiration but is highly influenced by position. Therefore, despite understanding the importance of “positioning” in respiratory physiotherapy, research on diaphragmatic excursion between body positions remains insufficient. This study examined the differences in diaphragm and chest wall excursion between supine, prone, and left and right side-lying positions to investigate the most suitable position for ventilation. Methods: Diaphragmatic excursion, as well as the lateral and anteroposterior diameters of the chest walls of 40 healthy adults (20 males and 20 females), was dynamically imaged during quiet breathing in 4 positions using magnetic resonance imaging, and the amount of excursion was calculated. The Friedman test was used for statistical analysis to compare differences in diaphragmatic and chest wall excursions. Results: The median age was 21.0 years, the median BMI was 20.8 kg/cm 2 , and all pulmonary function values were normal and within the reference values based on Japanese predicted normal values. The diaphragm and chest wall exhibited significantly greater excursion in the prone position than in other positions ( P < .001). In the side-lying position, the anteroposterior diameter excursion of the lower chest wall on the unloaded side was significantly greater ( P < .005). However, there was no significant difference between the side-lying and supine positions ( P > .05). Conclusions: Diaphragmatic and chest wall excursion during quiet breathing was found to be significantly greater in the prone position than in other positions. This suggests that the prone position is the optimal “positioning” for increased ventilation and may contribute to the prevention of respiratory complications.

• Neurolymphomatosis secondary to primary central nervous system lymphoma: illustrative case

  Journal of Neurosurgery Case Lessons · 2024-07-01

  articleOpen access

  BACKGROUND: Neurolymphomatosis (NL) is a rare disease defined as an invasion of lymphoma into peripheral nerves, nerve roots, or nerve plexuses, including the cranial nerves. No clear treatment protocols have yet been defined for this pathology. OBSERVATIONS: A woman in her 40s had a primary central nervous system lymphoma diagnosed from an intracranial tumor biopsy and underwent chemotherapy and radiation therapy. After she complained of pain in the trunk and extremities, magnetic resonance imaging and [18F]fluorodeoxyglucose (FDG) positron emission tomography (PET) performed 25 months after initial diagnosis revealed multiple lesions in the nerve ganglia, plexuses, and peripheral nerves from the cervical to the sacral spinal cord. Cerebrospinal fluid cytology revealed atypical lymphocytes and lymphoma dissemination in the spinal cavity. Based on these findings, NL was diagnosed. An intrathecal antineoplastic regimen temporarily reduced abnormal uptake of FDG, but the lesion recurred. After additional high-dose methotrexate therapy, FDG accumulation in the previously identified lesions disappeared. However, peripheral neuropathic pain and paraplegia remained. The patient died 9 months after the initial diagnosis of NL. LESSONS: The authors reported a case of NL following primary central nervous system lymphoma. In this case, FDG-PET proved useful for diagnosis, and high-dose methotrexate therapy was temporarily effective. https://thejns.org/doi/suppl/10.3171/CASE24107.

• Trends Favoring an Anatomical Approach to Radiofrequency Catheter Ablation of Idiopathic Ventricular Arrhythmias Originating From the Left Ventricular Summit

  Circulation Arrhythmia and Electrophysiology · 2024-04-17 · 10 citations

  article1st authorCorresponding

  BACKGROUND: Epicardial radiofrequency catheter ablation (RFCA) of idiopathic ventricular arrhythmias (VAs) originating from the left ventricular summit (LVS) is challenging because of the anatomic barriers. On the other hand, RFCA at the endocardial sites near the earliest epicardial activation site of LVS-VAs (anatomic approach) has proven successful. The evolving trends in the approaches and outcomes of RFCA of LVS-VAs at a single center were evaluated. METHODS: We studied 88 consecutive patients with idiopathic LVS-VAs at our institute from 2009 to 2019. These patients were divided into 3 periods: 2009 to 2012 (early), 2013 to 2015 (middle), and 2016 to 2019 (recent). The data were compared among the 3 periods. RESULTS: The RFCA success rate did not significantly change from the early to middle period but significantly increased from the middle to recent period ( P =0.0315). The transpericardial approach usage significantly decreased over the 3 periods. The anatomic approach usage significantly increased over the 3 periods. The use of the transpericardial approach did not affect the RFCA outcomes over the 3 periods. The success rate of the anatomic RFCA tended to increase from the early to middle period and significantly increased from the middle to recent period ( P =0.0412). The number of endocardial locations where RFCA was successful increased over the 3 periods. CONCLUSIONS: Over the 10-year period, the transpericardial approach became decreasingly performed, whereas the anatomic approach became increasingly performed with a satisfactory improvement in the RFCA outcomes of LVS-VAs. The anatomic RFCA became more successful by identifying more and various endocardial locations as target sites.
