Peak Frequency for Characterizing and Predicting Critical Isthmus and Termination Sites in Macro-Re-Entrant Atrial Tachycardia.

Background: Identifying critical isthmuses in macro-re-entrant atrial tachycardia (MRAT) is challenging. Omnipolar Technology Near Field mapping with the Peak Frequency (PF) tool holds promise for identifying critical regions sustaining re-entry, though PF signal characteristics and the algorithm's clinical value need further exploration.

Objectives: This study sought to analyze properties of PF in MRAT critical isthmuses and evaluate the value of Omnipolar Technology Near Field PF mapping in guiding ablation.

Intraoperative pectoral nerve blocks during cardiac implantable electronic device procedures.

Background: Cardiac implantable electronic device (CIED) procedures can cause significant postoperative pain. Opioid use for postoperative pain is associated with risk of persistent use. The benefits of pectoral nerve (PECs) blocks have been established for other chest wall surgeries, but adoption in electrophysiology has been limited.

Intraoperative ultrasound-guided pectoral nerve blocks for cardiac implantable device procedures.

Background: Pectoral nerve (PECs) blocks are established regional anesthesia techniques that can provide analgesia to the anterior chest wall. Although commonly performed preoperatively by anesthesiologists, the feasibility of electrophysiologist-performed PECs blocks from within cardiac implantable electronic device (CIED) pockets at the time of implantation has not been established. The objective of this study is to assess the feasibility of routine PECs blocks performed by the electrophysiologist from within the exposed device pocket at the time of CIED procedures.

Identifying Origin of Nonpulmonary Vein Triggers Using 2 Stationary Linear Decapolar Catheters: A Novel Algorithm.

Background: Targeting nonpulmonary vein triggers (NPVTs) of atrial fibrillation (AF) after pulmonary vein isolation can be challenging. NPVTs are often single ectopic beats with a surface P-wave obscured by a QRS or T-wave.

Objectives: The goal of this study was to construct an algorithm to regionalize the site of origin of NPVTs using only intracardiac bipolar electrograms from 2 linear decapolar catheters positioned in the posterolateral right atrium (along the crista terminalis with the distal bipole pair in the superior vena cava) and in the proximal coronary sinus (CS).

Deployment of AMMI, GGE-biplot and MTSI to select elite genotypes of castor ( L.).

Castor ( L.) is an important industrial multipurpose non-edible oilseed C crop belongs to spurge family popularly known as Euphorbiaceae. Its oil has exceptional properties which provides an industrial importance to this crop.

Safety of uterine artery embolization in patients with preexisting hydrosalpinx.

Purpose: To determine (i) if preexisting hydrosalpinx poses a risk for development of pyosalpinx following uterine artery embolization (UAE) and (ii) the effect of UAE on fallopian tube diameter.

Materials And Methods: Between 2005 and 2011, 429 women underwent UAE for treatment of symptomatic leiomyomas. Magnetic resonance (MR) imaging before UAE revealed 16 (3.

Coccygeoplasty: treatment for fractures of the coccyx.

Percutaneous vertebroplasty and sacroplasty are becoming common modalities of treatment for vertebral body compression fractures and sacral insufficiency fractures, respectively. The present report describes a case of a coccygeal fracture treated with injection of polymethylmethacrylate cement, which resulted in immediate relief of symptoms. It is suggested that this procedure be called coccygeoplasty.

Intradiskal extravasation with low-volume cement filling in percutaneous vertebroplasty.

Background And Purpose: Adjacent fracture formation after percutaneous vertebroplasty has been reported in literature. The purpose of this study was to determine whether intervertebral disk extravasation is related to adjacent fracture formation in low-volume cement-filling vertebroplasty.

Methods: A retrospective analysis of 308 patients having vertebroplasty was undertaken.

New symptomatic vertebral compression fractures within a year following vertebroplasty in osteoporotic women.

Background And Purpose: Percutaneous vertebroplasty has been performed in the United States in an increasing volume since the mid-1990s. The purpose of this study is to analyze the risk of a new symptomatic vertebral compression fractures within 1 year of having an acute/subacute fracture treated with vertebroplasty.

Methods: A retrospective analysis was performed in which 253 female patients were found to have acute/subacute vertebral compression fractures secondary to osteoporosis treated with percutaneous vertebroplasty.
