Abnormally rapid heartbeats caused by reentry of atrial impulse into the dual (fast and slow) pathways of ATRIOVENTRICULAR NODE. The common type involves a blocked atrial impulse in the slow pathway which reenters the fast pathway in a retrograde direction and simultaneously conducts to the atria and the ventricles leading to rapid HEART RATE of 150-250 beats per minute.
Recording of regional electrophysiological information by analysis of surface potentials to give a complete picture of the effects of the currents from the heart on the body surface. It has been applied to the diagnosis of old inferior myocardial infarction, localization of the bypass pathway in Wolff-Parkinson-White syndrome, recognition of ventricular hypertrophy, estimation of the size of a myocardial infarct, and the effects of different interventions designed to reduce infarct size. The limiting factor at present is the complexity of the recording and analysis, which requires 100 or more electrodes, sophisticated instrumentation, and dedicated personnel.

Non-thermal ablation of rabbit liver VX2 tumor by pulsed high intensity focused ultrasound with ultrasound contrast agent: Pathological characteristics. (4/191)

AIM: To investigate the pathological characteristics of non-thermal damage induced by pulsed high intensity focused ultrasound (PHIFU) combined with ultrasound contrast agent (UCA), SonoVue (Bracco SpA, Milan, Italy) in rabbit liver VX2 tumor. METHODS: Liver VX2 tumor models were established in 20 rabbits, which were divided randomly into PHIFU combined with ultrasound contrast agent group (PHIFU + UCA group) and sham group. In the PHIFU + UCA group, 0.2 mL of SonoVue was injected intravenously into the tumor, followed by ultrasound exposure of I(SP) 5900 W/cm(2). The rabbits were sacrificed one day after ultrasound exposure. Specimens of the exposed tumor tissues were obtained and observed pathologically under light microscope and transmission electron microscope. The remaining tumor tissues were sent for 2,3,5-Triphenyltetrazolium chloride (TTC) staining. RESULTS: Before TTC staining, tumor tissues in both the sham and the PHIFU + UCA groups resembled gray fish meat. After TTC staining, the tumor tissues were uniformly stained red, with a clear boundary between tumor tissue and normal tissue. Histological examination showed signs of tumor cell injury in PHIFU + UCA group, with cytoplasmic vacuoles of various sizes, chromatin margination and karyopyknosis. Electron microscopic examination revealed tumor cell volume reduction, karyopyknosis, chromatin margination, intercellular space widening, the presence of high electron-density apoptotic bodies and vacuoles in cytoplasm. CONCLUSION: The non-thermal effects of PHIFU combined with UCA can be used to ablate rabbit liver VX2 tumors.  (+info)

Background: Irreversible electroporation (IRE) is a local ablation technique utilizing high voltage, low energy direct current to create nanopores in cell membrane which disrupt homeostasis and leads to cell death. Previous reports have suggested IRE may have a role in treating borderline resectable and unresectable Stage 3 pancreatic tumors. Methods: Patients with Stage 3 pancreatic ductal adenocarcinoma (PDAC) will be enrolled in either a randomized, controlled, multicenter trial (RCT) or a multicenter registry study. Subjects enrolled in the RCT must have no evidence of disease progression after 3 months of modified FOLFIRINOX (mFOLFIRINOX) treatment prior to being randomization to either a control or IRE arm. Post-induction and post-IRE treatment for the control and IRE arms, respectively, will be left to the discretion of the treating physician. The RCT will enroll 528 subjects with 264 per arm and include up to 15 sites. All subjects will be followed for at least 24 months or until death. The

10. Multilateral action necessarily demands an organizational framework. The United Nations, in particular, is and should remain the primary venue for cooperation and coordination between nations, though regional forums have an important role to play in this regard as well. The United Nations is an imperfect institution, and many ideas for institutional reform have been mooted. Institutions, however, reflect the capacity of their members to work together. No state can expect that its policies will be accepted at all times by the community of nations. The UNs achievements are the result of the dedication of its major members, and its failures are due to lack of support by member states. Institutional changes in the United Nations are very unlikely to occur even in the medium term - the urgent and central task of todays leaders must be to work effectively with the organizations that exist and the tools at hand. The vital role of the Security Council remains central to todays international ...

A new method for the ablation of undesirable tissue such as cells of a cancerous or non-cancerous tumor is disclosed. It involves the placement of electrodes into or near the vicinity of the undesirable tissue through the application of electrical pulses causing irreversible electroporation of the cells throughout the entire area of the undesirable tissue. The electric pulses irreversibly permeate the cell membranes, thereby invoking cell death. The irreversibly permeabilized cells are left in situ and are removed by the body immune system. The amount of tissue ablation achievable through the use of irreversible electroporation without inducing thermal damage is considerable.
To report on the first short-term oncologic outcomes of percutaneous irreversible electroporation for small renal masses.Patients with cT1a renal masses treated with irreversible electroporation from April 2013 through December 2016 were reviewed.
Irreversible electroporation is a minimally invasive technique for the non-thermal destruction of cells in a targeted volume of tissue, using brief electric pulses, (~100 µs long) delivered through electrodes placed into or around the targeted region. These electric pulses destabilize the integrity of the cell membrane, resulting in the creation of nanoscale defects that increase a cells permeability to exchange with its environment. When the energy of the pulses is high enough, the cell cannot recover from these effects and dies in a non-thermal manner that does not damage neighboring structures, including the extracellular matrix. IRE has been shown to spare the major vasculature, myelin sheaths, and other supporting tissues, permitting its use in proximity to these vital structures. This technique has been proposed to be harnessed as an advantageous non-thermal focal ablation technique for diseased tissues, including tumors. IRE electric pulses may be delivered through small (ø ≈ 1 mm) ...

PurposeNumerical simulations are used for treatment planning in clinical applications of irreversible electroporation (IRE) to determine ablation size and shape. To assess the reliability of simulations for treatment planning, we compared simulation results with empiric outcomes of renal IRE using computed tomography (CT) and histology in an animal model.MethodsThe ablation size and shape for six different IRE parameter sets (70-90 pulses, 2,000-2,700 V, 70-100 µs) for monopolar and bipolar electrodes was simulated using a numerical model. Employing these treatment parameters, 35 CT-guided IRE ablations were created in both kidneys of six pigs and followed up with CT immediately and after 24 h. Histopathology was analyzed from postablation day 1.ResultsAblation zones on CT measured 81 ± 18 % (day 0, p ≤ 0.05) and 115 ± 18 % (day 1, p ≤ 0.09) of the simulated size for monopolar electrodes, and 190 ± 33 % (day 0, p ≤ 0.001) and 234 ± 12 % (day 1, p ≤ 0.0001) for bipolar electrodes. ...

Exposing a biological cell to an electric field results in structural changes in the cell plasma membrane. If the electric field is sufficiently high, the changes in the trans-membrane voltage cause the membrane to become permeable to molecules which otherwise cannot cross it. The described phenomenon is termed electroporation [1] and can be either reversible or irreversible. If the electric field at given pulse characteristics exceeds the reversible electroporation threshold, the cell eventually returns to its normal state and survives; this is called reversible electroporation. However, if the electric field exceeds the threshold of irreversible electroporation or the cell is exposed to the electric field too long, the changes in the membrane lead to irreversible electroporation (IRE) characterized by cell death.. Both reversible and irreversible electroporation have found their use in treatment of tumors [2]. Combination of reversible electroporation and cytotoxic drugs used in chemotherapy ...
Background: Tumor ablative therapies like percutaneous cryoablation or microwave ablation have been developed to reduce tumor burden when surgical resection is not feasible. Ablation can treat multiple lesions, save more uninvolved tissue with considerably minimal morbidity and the 5 year survival rate approaches that of surgical resection. Infectious complications associated with ablative therapy have not been previously studied. Methods: This retrospective, cross-sectional study was conducted at the Karmanos Cancer Center. Patients who underwent cryoablations or microwave ablation for hepatic and/or renal tumors between January 1, 2003 and October 31, 2012 were included. Infectious complications occurring within 60 days of index procedure were recorded. Results: 377 Patients underwent tumor ablative procedures. 362 cryoablations, 15 microwave ablations were performed for 205 (54%) renal and 172 (46%) liver lesions. Mean age of the cohort was 63.5 ± 13 years, 196 (52%) were men and 201 (53%) ...

Background and aim: Imaging guided microwave ablation (MWA) for hepatocellular carcinoma (HCC) hasbecome a widely used method over recent years. Tumors close to the diaphragm, gastrointestinal tract, gallbladder,pancreas, hepatic hilum and major bile duct or vessels are generally considered relative contraindications for microwaveablation. This study was conducted to assess the effectiveness and safety of ultrasonography-guided MWA in treatingpatients with HCC in difficult anatomical sites in comparison to those in conventional sites. Patients and methods:Eighty-eight patients were included and divided into two groups: the study group of 44 with 46 lesions lying |5mmfrom the diaphragm, hepatic capsule, gall bladder (GB) or large vessel; and the control group of 44 patients with50 lesions in non-risky sites. Each lesion was ablated using an ultrasound guided microwave probe using a detailedprotocol. Results: Most of the patients were males, with a mean age of 57.8 years. In the study group, two
The selective infusion of ethanol into the coronary circulation supplying the site of origin of incessant ventricular tachycardia has been demonstrated to abolish this arrhythmia in selected patients. The present study was designed to evaluate the efficacy and safety of the intracoronary ethanol ablation technique in patients with paroxysmal ventricular tachycardia related to prior myocardial infarction. Twenty-three patients with sustained monomorphic ventricular tachycardia that was refractory to conventional antiarrhythmic drug therapy were prospectively studied. After induction of ventricular tachycardia by programmed electrical stimulation, the response of the arrhythmia to the infusion of radiographic contrast medium or saline solution into the ostia of the native coronary arteries and coronary artery bypass grafts was assessed. If ventricular tachycardia was reliably interrupted by injections into the proximal coronary artery or bypass graft, the vessel was cannulated with a steerable guide wire

The inner conductor and the outer conductor cooperate to emit an electromagnetic field sufficiently strong to cause tissue ablation in a direction generally away from the flared interior wall of the outer conductor.
PURPOSE: To evaluate preliminary outcomes after microwave ablation (MWA) of hepatocellular carcinoma (HCC) up to 5 cm and to determine the influence of tumor size. MATERIALS AND METHODS: Electronic records were searched for HCC and MWA. Between January 2011 and September 2014, 173 HCCs up to 5 cm were treated by MWA in 129 consecutive patients (89 men, 40 women; mean age, 66.9 y ± 9.5). Tumor characteristics related to local tumor progression and primary and secondary treatment efficacy were evaluated by univariate analysis. Outcomes were compared between tumors ≤ 3 cm and tumors | 3 cm. RESULTS: Technical success, primary efficacy, and secondary efficacy were 96.5%, 99.4%, and 94.2% at a mean follow-up period of 11.8 months ± 9.8 (range, 0.8-40.6 mo). Analysis of tumor characteristics showed no significant risk factor for local tumor progression, including subcapsular location (P = .176), tumor size (P = .402), and perivascular tumor location (P = .323).

Hypertrophic cardiomyopathy (HCM) is a genetic disease occurring in approximately one in 500-1000 of the general population. HCM is often undiagnosed or misdiagnosed, and asymptomatic cases are often unrecognized. Asymmetric left ventricular (LV) hypertrophy (LVH) most often develops during the period of rapid body growth of adolescence, but it may be present in childhood or, rarely, before birth. Progressive LVH after age 20 is uncommon, but initial diagnosis even in old age is not. The hypertrophy predominantly involves the LV, and is often more marked than in any other cardiac disease. Hypertrophy may involve the right ventricle (RV), and an atrial myopathy may be progressive (left atrial enlargement [LA) and increased risks of atrial fibrillation [AF]). RV and LA involvement may be secondary to the LV disease, and/or a primary consequence of the basic molecular defect. The LVH represents hypertrophy and hyperplasia of several cell types, including cardiac myocytes, fibroblasts, and smooth muscle

Differentiated thyroid cancer (DTC) is the most common endocrine malignancy with the highest mortality although with appropriate treatment has a good long-term prognosis and cure rate. Over the last 30 years there is a worldwide trend showing an increasing incidence of thyroid cancer. In DTC patients, total thyroidectomy has been for many decades routinely followed by the administration of radioiodine (131I) activity to destroy remnant thyroid tissue. Several reasons are in favour to routine ablation of postoperative thyroid remnants. The combination of both surgery and radioiodine has proven as a safe and effective treatment, resulting in improved life expectation and reduced recurrence rate for DTC patients. Recently, however, 131I ablation is not uniformly recommended for cancers smaller than 10 mm, and its use is debated for papillary tumours with diameter between 10 and 20 mm. Indeed, the decision about subsequent 131I thyroid remnant ablation is recommended as individualized and ...
TY - JOUR. T1 - Novel methods for renal tissue ablation. AU - Olweny, Ephrem O.. AU - Cadeddu, Jeffrey A. PY - 2012/9/1. Y1 - 2012/9/1. N2 - PURPOSE OF REVIEW: To provide an overview of the current research on renal tissue ablation, highlighting novel ablation techniques and technologies. RECENT FINDINGS: As long-term data on renal radio frequency ablation (RFA) and cryoablation confirming their oncologic efficacy emerge, ongoing research aims at improving the treatment profiles of these techniques as well as developing novel methods for renal tissue ablation. SUMMARY: Although nephron-sparing surgery is the gold standard treatment for small renal masses confirmed malignant, ablative therapies are an option in elderly patients, who may be poor surgical candidates. RFA and cryoablation have each been used for renal tissue ablation for over a decade but their efficacy in ablation of central lesions or lesions more than 3cm in size is limited. Increasing ablation size and improving efficiency of ...
Papillary thyroid carcinoma (PTC) is the most common subtype of thyroid malignancy and has a good prognosis and low mortality rate. Surgery is the standard treatment for patients with primary and recurrent thyroid cancer. Although patients with PTC usually exhibit excellent treatment outcome, the incidence of recurrence in the neck ranges from 20% to 59%. When a patient with thyroid cancer is contraindicated for surgery, ultrasound (US)-guided ablation techniques, including ethanol ablation (EA) and thermal ablations, are suggested alternatives. In this review, we evaluated the indications, devices, techniques, clinical outcomes, and complications associated with US-guided EA and thermal ablations based on available scientific evidence and expert opinions regarding the use of ablation for primary and recurrent thyroid cancers.
0010] Some or all of these embodiments may provide one or more of the following advantages. First, the thermochemical ablation techniques may provide minimally invasive ablation of solid tumors (e.g., liver cancer, lung cancer, renal cancer, breast cancer, prostate cancer, sarcomas, or the like) or other tissues including varicoceles, varicose veins, or the like. Such techniques may be useful, for example, to treat patients who are not surgical candidates due to the nature of the tumors or other intervening factors. Second, the thermochemical ablation techniques may induce chemical reactions to generate heat either to be the primary ablation source or to augment another ablation source (e.g., RF ablation, microwave ablation, denaturant sources such as sclerosants, detergents, or urea, or other ablation sources). Third, the chemical reactions may be induced by mixing at least one acid reagent and at least one base reagent, thereby reducing or eliminating the acid or base load applied to the ...

Rezūm uses the stored thermal energy in water vapor (steam) to treat the extra prostate tissue that is causing symptoms such as frequency, urgency, irregular flow, weak stream, straining and getting up at night to urinate.. Inside a hand-held device, radiofrequency energy is applied to a few drops of water to create vapor (steam). The water vapor is injected into the prostate tissue that is blocking the flow of urine from the bladder, where it immediately turns back to water, releasing the energy stored in the vapor into the cell membranes. At this point, the cells are gently and immediately damaged, causing cell death. Over time, the body absorbs the treated tissue through its natural healing response. ...
A minimally invasive therapy that uses water vapor to ablate prostate tissue can effectively treat recalcitrant urinary retention in men.
In this work we investigate the luminescent properties of HfO2 films doped with Eu-3*, Tb3+ and Eu3+ + Tb3+ ions excited through photoluminescence and cathodoluminescence. These films were synthesized by the pulsed laser ablation technique and structurally studied by X-ray diffraction and Raman spectroscopy; the surface morphology was observed by scanning electron and atomic force microscopies. The optical transmittance was measured as well. The crystalline phase observed was the monoclinic of the HfO2. The surface morphology of the films exhibited a low roughness, as measured by atomic force microscopy. These films show a high transparency in the visible region. The emission spectra show bands centered at 598, 614 (strongest emission), and 631 nm for the HfO2:Eu3+ films under excitation of 267.nm. HfO2:Tb3+ films when excited at 277 nm exhibit emission bands centered at 491, 543 (dominant emission), 551 and 586 nm. In the case of co-doping with Eu3+ and Tb3+ ions white emission was observed ...
