Os malefícios da "Luva Chupeta" de látex na Unidade Neonatal / The harmful effects of the latex "Glove Pacifier" in the Neonatal Unit / Los efectos nocivos del "Guante Chupete" de látex em La Unidad Neonatal

Na Iniciativa Hospital Amigo da Criança-Neofoi proposto o uso da chupeta na Unidade Neonatal (UN) de modo terapêutico, e sempre com supervisão de um profissional de saúde. Mas observa-se que o aparato conhecido como "Luva Chupeta" fabricado com o uso de uma luva de látex está sendo utilizado como alternativa para acalentar o recém-nascido (RN). Apesar de poucos estudos, é evidente que esse dispositivo deve ser contraindicado na UN, uma vez que pode provocar alergia ao látex, transmitir infecções, provocar acidentes graves como aspiração laringotraqueal do algodão devido ao rompimento da luva de látex, e dependendo do tamanho do material, obstruir as vias aéreas, e levar a óbito. Além do mais, o dispositivo pode interferir negativamente no crescimento e no desenvolvimento craniofacial e causar prejuízos associados à amamentação e na saúde materno infantil. A substituição da "Luva Chupeta" por outras estratégias, até mesmo pela chupeta convencional ou ortodôntica, para lidar com a dor e situações de estresse do RN deve ser decisiva para evitar os riscos de acidentes graves. O Protocolo de uso de bicos, Protocolo de manejo da dor do RN, adoção do Método Canguru na UN para promoção do desenvolvimento e comportamento do RN, e a capacitação/monitoramento das práticas adotas pela Equipe Materno Infantil, quanto ao cuidado ofertado são alternativas mais complexas, mas que devem ser analisadas por aqueles que desejam oferecer confiabilidade aos seus processos institucionais.

In the Baby-Friendly Hospital-Neo Initiative, the use of pacifiers in the Neonatal Unit (UN) was proposed in a therapeutic way, and always under the supervision of a health professional. However, it should be noted that the device known as "Pacifier Glove" manufactured using a latex glove is being used as an alternative to cherish the newborn. Despite few studies, it is clear that this device should be contraindicated in the UN, since it can cause allergy to latex, transmit infections, cause serious accidents such as laryngotracheal aspiration of cotton due to the rupture of the latex glove, and depending on the size of the material, obstruct the airways, and lead to death. Furthermore, the device may interfere with craniofacial growth and development and cause harm associated with breastfeeding and maternal and child health. The substitution of the "Pacifier Glove" for other strategies, even for the conventional or orthodontic pacifier, to deal with the pain and stress situations of the baby should be avoided to avoid the risk of serious accidents.The teat use protocol, the baby's pain management protocol, the adoption of the Kangaroo Method in the neonatal unit to promote the baby's development and behavior, and the training/monitoring of the practices adopted by the Maternal and Child Team, regarding the care offered, are alternatives more complex, but which must be analyzed by those who wish to offer reliability to their institutional processes.

En la Iniciativa Hospital Amigo del Niño-Neo, se propuso terapéuticamente el uso del chupete en la Unidad Neonatal (UN), y siempre bajo la supervisión de un profesional de la salud. Pero se observa que el dispositivo conocido como "chupete Gluva", fabricado con el uso de un guante de látex, está siendo utilizado como una alternativa para cuidar al recién nacido (NB). A pesar de los pocos estudios, es evidente que este dispositivo debe estar contraindicado en la NU, ya que puede causar alergia al látex, transmitir infecciones, ocasionar accidentes graves como aspiración laringotraqueal de algodón por rotura del guante de látex, y dependiendo de la El tamaño del material obstruye las vías respiratorias y provoca la muerte. Además, el dispositivo puede interferir negativamente con el crecimiento y desarrollo craneofacial y causar daños asociados con la lactancia materna y la salud maternoinfantil. La sustitución del "Dummy Glove" por otras estrategias, incluso el chupete convencional u ortodóncico, para hacer frente a las situaciones de dolor y estrés del RN debe ser determinante para evitar el riesgo de accidentes graves. El Protocolo de Uso del Pezón, el Protocolo de Manejo del Dolor del RN, la adopción del Método Canguro en la NU para promover el desarrollo y comportamiento del RN, y la capacitación/seguimiento de las prácticas adoptadas por el Equipo Materno Infantil, en cuanto a los cuidados ofrecidos, son más alternativas eficientes, complejas, pero que deben ser analizadas por quienes deseen brindar confiabilidad a sus procesos institucionales.

Actualización sobre las contraindicaciones en cirugía refractiva láser corneal / Update on contraindications in laser corneal refractive surgery

Los más de 25 años de experiencia con las técnicas de cirugía refractiva (desde que se aprobara por la Food and Drug Administration [FDA] de EE. UU. el uso del láser excímer en el remodelamiento de la córnea en 1995), sumado a los avances tecnológicos en oftalmología (láser de femtosegundo, ablación guida por topografía, sistemas de imagen de segmento anterior) y el mayor entendimiento de los errores refractivos, las aberraciones de alto orden y la biomecánica corneal, hacen que la cirugía refractiva corneal con láser sea un método seguro y eficaz para la corrección de estos defectos. Sin embargo, a día de hoy, siguen existiendo ciertas circunstancias que suponen una contraindicación para su aplicación, además de otras que podrían asociarse a complicaciones, y que deben ser analizadas con detenimiento.Esta revisión repasa las contraindicaciones actuales para la cirugía refractiva corneal con láser recogidas en los Protocolos de Práctica Preferente (PPP) de la Academia Estadounidense de Oftalmología y de la Sociedad Española de Oftalmología. Estos protocolos están basados en la mayor evidencia científica disponible en la actualidad y permiten extraer recomendaciones claras, mejorando el perfil de seguridad de estas técnicas.Las contraindicaciones pueden diferenciarse en relativas o absolutas; entre estas últimas están: la edad inferior a 18 años, la ausencia de estabilidad refractiva y la existencia de ciertas afecciones oculares (entre las que destacan determinadas distrofias corneales, queratocono, ojo seco mal controlado) o sistémicas (procesos autoinmunes activos o diabetes mellitus mal controlada)...(AU)

More than 25 years of experience with refractive surgery techniques (since the FDA [Food and Drug Administration] of the United States approved the use of the excimer laser in the remodeling of the cornea in 1995), added to the technological advances in ophthalmology (femtosecond laser, topography-guided ablation, anterior segment imaging systems) and increased understanding of refractive errors, higher order aberrations, and corneal biomechanics make corneal laser refractive surgery a safe method and effective for the correction of these defects. However, to date, there are still certain circumstances that represent a contraindication for its application, in addition to others that could be associated with complications, and that must be carefully analyzed.This review analyzes the current contraindications for laser corneal refractive surgery listed in the Preferred Practice Protocols (PPPs) of the American Academy of Ophthalmology and the Spanish Ophthalmology Society. These protocols are based on the best scientific evidence currently available and allow clear recommendations to be drawn, improving the safety profile of these techniques.Contraindications can be differentiated into relative or absolute; among the latter are: age less than 18 years, the absence of refractive stability and the existence of certain ocular pathologies (including certain corneal dystrophies, keratoconus, poorly controlled dry eye) or systemic pathologies (active autoimmune processes or poorly controlled diabetes mellitus). Other circumstances such as the use of certain drugs (amiodarone, isotretinoin), extreme values of mean central keratometry and pachymetry, history of previous uveitis or glaucoma, pregnancy and lactation, are considered relative contraindications according to the PPPs. However, there are studies that demonstrate the safety of refractive surgery in some of these cases. (AU)

[Nerve biopsy in the diagnosis of peripheral neuropathies]. / La biopsie nerveuse dans le diagnostic des neuropathies périphériques.

The indications for nerve biopsy have diminished in recent years. This examination nevertheless remains essential in certain cases of peripheral neuropathies, making it possible to specify the diagnosis or the mechanism of injury for a therapeutic purpose. It is a simple but "invasive" procedure, which can only be performed once on the same nerve. The indications are thus discussed on a case-by-case basis and based on a range of clinical, electrophysiological, biological or even genetic arguments. This involves close collaboration between clinical physicians and pathologists. The main difficulty of this biopsy concerns the fragility of the sample and the techniques necessary for its interpretation, requiring it to be carried out in expert centers. Nerve biopsy is closely related to skin biopsy in the search for small fiber neuropathy. It is a particular technique, but very well codified. The purpose of this review is to recall the indications and contraindications of nerve biopsy, and to explain what the contributions are but also the limits of this examination as well as of skin biopsy.

Técnica minimalista para valvuloplastía aórtica percutánea / Minimally invasive balloon aortic valve valvuloplastyBackground

RESUMEN: ANTECEDENTES: La valvuloplastía aórtica es un procedimiento paliativo o como puente al reemplazo aórtico percutáneo o quirúrgico. Nuestro abordaje incluye una técnica minimalista y la utilización de balones de mayor tamaño que lo estándar. OBJETIVO: Evaluar los resultados clínicos inmediatos y alejados de pacientes tratados mediante esta técnica modificada. MÉTODOS: Se incluyó a todos los pacientes sometidos a balonplastía aórtica entre Julio del 2012 y Agosto del 2019 en nuestro centro. El procedimiento se realizó bajo sedación consciente mediante un único acceso femoral y sin instalación de un marcapasos transitorio. El éxito de la intervención se definió como caída de gradiente basal en 50% o más en ausencia de complicación mayor. RESULTADOS: Se realizaron un total de 52 procedimientos en 49 pacientes. La edad promedio fue 76 ± 9,9 años. Un tercio de los pacientes tenía una fracción de eyección del ventrículo izquierdo ≤35% y similar proporción tenía un perfil de riesgo STS score > 10 puntos. La duración total promedio fue de 31,1 + 10,0 min. Se utilizó un balón #28 en el 84.6% de los casos. El éxito del procedimiento se alcanzó en 94,2% de los casos. Ocurrieron 2 muertes intraoperatorias (3,9%), ambas en pacientes de muy alto riesgo y 2 (3,9%) complicaciones vasculares mayores. La sobreviva en el seguimiento alejado fue 32,7%. CONCLUSIÓN: La valvuloplastia aórtica percutánea con técnica modificada, utilizando balones de mayor tamaño que lo habitual, es una técnica segura que logra óptimos resultados hemodinámicos.

ABSTRACT: Aortic balloon valvuloplasty (ABV) is a palliative procedure or a bridge to percutaneous or surgical aortic valve replacement. Our group proposes a minimalist approach that reduces the use of resources and also stands out for using larger balloons. AIM: To assess the safety and the immediate results of patients undergoing aortic balloon valvuloplasty using a minimally invasive procedure. METHODS: All patients who underwent ballon aortic valvuloplasty (BAV) between July 2012 and Au- gust 2019 were included. The procedure was performed under conscious sedation using a single femoral access and without the installation of a temporary pacemaker. Success was defined as a 50% drop in the mean aortic gradient plus the absence of major complications. RESULTS: 52 procedures in 49 patients were performed; the average age was 76 ± 9,9 years. A third of patients included had a left ventricular ejection fraction ≤35% and a similar proportion had a high risk profile with an STS score> 10 points. A 28 mm balloon was used in 84.6% of cases. The procedure was successful in 94,2% of cases. There were 2 (3,85%) intraoperative deaths in very high-risk patients and 2 (3,85%) major vascular complications. The survival rate at late follow up was 32,7%. CONCLUSION: Aortic balloon valvuloplasty with a minimally invasive technique using larger than usual balloons is a safe technique that achieves optimal hemodynamic results.

Bilateral Lung Transplant for Treatment of Idiopathic Pulmonary Fibrosis With Undetected Lung Adenocarcinoma: A Case Report.

BACKGROUND: Lung transplant has become a curative therapy for various forms of progressive lung disease refractory to medical management. Idiopathic pulmonary fibrosis (IPF) is a rare condition characterized by accumulation of activated fibroblasts and secretion of extracellular matrices within the lung parenchyma. End-stage IPF is a fatal condition, with limited medical therapies other than lung transplantation. IPF has been demonstrated as a known risk factor for the development of lung cancer, and current lung transplant standards define history of malignancy within the past five years as an absolute exclusion criterion. CASE REPORT: We present the case of a patient with biopsy-confirmed idiopathic pulmonary fibrosis treated with bilateral lung transplant, discovered to have stage four lung adenocarcinoma in the explanted lungs. The patient subsequently received pseudoadjuvant chemotherapy and remained recurrence-free until 23 months post-transplant. CONCLUSION: This case highlights the challenge of ruling out malignancy in patients with end-stage lung disease. There remains a paucity of clinical studies on lung transplantation for lung cancer and more evidence is required before supporting this clinical decision.

Radiotherapy for patient with cardiac implantable electronic device, consensus from French radiation oncology society.

Radiotherapy in patients with cardiac implantable electronic device such as pacemakers or defibrillators, is a clinical situation that is becoming increasingly common. There is a risk of interaction between the magnetic field induced by accelerators and the cardiac implantable electronic device, but also a risk of device dysfunction due to direct and/or indirect irradiation if the cardiac implantable electronic device is in the field of treatment. The risk can be dose-dependent, but it is most often independent of the total dose and occurs randomly in case of neutron production (stochastic effect). The presence of this type of device is therefore described as a contraindication for radiotherapy by the French national agency for the safety of medicines and health products (Agence nationale de sécurité du médicament et des produits de santé, ANSM). Nevertheless, since radiotherapy is often possible, it is advisable to respect the recommendations of good practice, in particular the eligibility criteria, the monitoring modalities before, during and after irradiation according to the type of treatment, the dose and the characteristics of the cardiac implantable electronic device. It is sometimes necessary to discuss repositioning the device and/or modifying the treatment plan to minimize the risk of cardiac implantable electronic device dysfunction. We present the update of the recommendations of the French society of oncological radiotherapy on in patients with cardiac implantable electronic device.

Is Uterine Myomectomy a Real Contraindication to Vaginal Delivery? Results from a Prospective Study.

OBJECTIVES: The main goal of our research was to explore correlations between a history of uterine myomectomy and maternal-fetal outcomes, throughout a comparison between vaginal deliveries in patients with or without a history of uterine myoma excision. MATERIALS AND METHODS: A prospective study was carried out at two tertiary care hospitals between January 2019 and January 2020. Women were assigned into two groups according to the history of laparoscopic or laparotomic myomectomy (Group 1) or without myomectomy (Group 2). RESULTS: 80 women successfully delivered after myomectomy. Pregnancies with previous laparoscopic or laparotomic myomectomy were associated with a minor rate of spontaneous labor onset (RR 1.17; 95% CI 1.04 - 1.31) and with an increased rate of emergency cesarean section (RR 1.22; 95% CI 1.09 - 1.36). Moreover, myomectomy group had a significant number of indications to emergency cesarean section correlated to suspected uterine rupture (RR 1.19; 95% CI 1.02-1.39). There were no uterine ruptures or neonatal deaths recorded. First stage of labor was longer in the myomectomy group (316 vs 204 mins, p = 0.01). No differences in the rates of the prolonged first and second stage of labor, postpartum hemorrhage and vaginal laceration, and no neonatal adverse outcomes were found between groups. CONCLUSIONS: Pregnancies after myomectomy might be associated with an elevated rate of emergency cesarean section only due to a higher percentage of suspected uterine rupture, without a real hazard of adverse obstetric or neonatal outcomes.

Resuscitative Endovascular Balloon Occlusion of Aorta: A Systematic Review.

BACKGROUND: The data on resuscitative endovascular balloon occlusion of the aorta (REBOA) use continue to grow with its increasing use in trauma centers. The data in her last 5 years have not been systematically reviewed. We aim to assess current literature related to REBOA use and outcomes among civilian trauma populations. METHODS: A literature search using PubMed, EMBASE, and JAMA Network for studies regarding REBOA usage in civilian trauma from 2016 to 2020 is carried out. This review followed preferred reporting items for systematic reviews and meta-analysis guidelines. RESULTS: Our search yielded 35 studies for inclusion in our systematic review, involving 4073 patients. The most common indication for REBOA was patient presentation in hemorrhagic shock secondary to traumatic injury. REBOA was associated with significant systolic blood pressure improvement. Of 4 studies comparing REBOA to non-REBOA controls, 2 found significant mortality benefit with REBOA. Significant mortality improvement with REBOA compared to open aortic occlusion was seen in 4 studies. In the few studies investigating zone placement, highest survival rate was seen in patients undergoing zone 3. Overall, reports of complications directly related to overall REBOA use were relatively low. CONCLUSION: REBOA has been shown to be effective in promoting hemodynamic stability in civilian trauma. Mortality data on REBOA use are conflicting, but most studies investigating REBOA vs. open occlusion methods suggest a significant survival advantage. Recent data on the REBOA technique (zone placement and partial REBOA) are sparse and currently insufficient to determine advantage with any particular variation. Overall, larger prospective civilian trauma studies are needed to better understand the benefits of REBOA in high-mortality civilian trauma populations. STUDY TYPE: Systematic Review. LEVEL OF EVIDENCE: III- Therapeutic.

Patient-Specific Computational Analysis of Hemodynamics in Adult Pulmonary Hypertension.

Pulmonary hypertension (PH) is a progressive disease characterized by elevated pressure and vascular resistance in the pulmonary arteries. Nearly 250,000 hospitalizations occur annually in the US with PH as the primary or secondary condition. A definitive diagnosis of PH requires right heart catheterization (RHC) in addition to a chest computed tomography, a walking test, and others. While RHC is the gold standard for diagnosing PH, it is invasive and posseses inherent risks and contraindications. In this work, we characterized the patient-specific pulmonary hemodynamics in silico for diverse PH WHO groups. We grouped patients on the basis of mean pulmonary arterial pressure (mPAP) into three disease severity groups: at-risk ([Formula: see text], denoted with A), mild ([Formula: see text], denoted with M), and severe ([Formula: see text], denoted with S). The pulsatile flow hemodynamics was simulated by evaluating the three-dimensional Navier-Stokes system of equations using a flow solver developed by customizing OpenFOAM libraries (v5.0, The OpenFOAM Foundation). Quasi patient-specific boundary conditions were implemented using a Womersley inlet velocity profile and transient resistance outflow conditions. Hemodynamic indices such as spatially averaged wall shear stress ([Formula: see text]), wall shear stress gradient ([Formula: see text]), time-averaged wall shear stress ([Formula: see text]), oscillatory shear index ([Formula: see text]), and relative residence time ([Formula: see text]), were evaluated along with the clinical metrics pulmonary vascular resistance ([Formula: see text]), stroke volume ([Formula: see text]) and compliance ([Formula: see text]), to assess possible spatiotemporal correlations. We observed statistically significant decreases in [Formula: see text], [Formula: see text], and [Formula: see text], and increases in [Formula: see text] and [Formula: see text] with disease severity. [Formula: see text] was moderately correlated with [Formula: see text] and [Formula: see text] at the mid-notch stage of the cardiac cycle when these indices were computed using the global pulmonary arterial geometry. These results are promising in the context of a long-term goal of identifying computational biomarkers that can serve as surrogates for invasive diagnostic protocols of PH.

Clinically non-functioning pituitary adenomas.

Clinically non functioning pituitary adenomas (NFPAs) include all pituitary adenomas that are not hormonally active. They are not associated with clinical syndromes such as amenorrhea-galactorrhea (prolactinomas), acromegaly, Cushing's disease or hyperthyroidism (TSH-secreting adenomas) and are therefore usually diagnosed by signs and symptoms related to a mass effect (headache, visual impairment, sometimes pituitary apoplexy), but also incidentally. Biochemical work up often documents several pituitary insufficiencies. In histopathology, the majority of NFPAs are gonadotroph. In the absence of an established medical therapy, surgery is the mainstay of treatment, unless contraindicated or in particular situations (e.g. small incidentalomas, distance from optic pathways). Resection, generally via a trans-sphenoidal approach (with the help of an endoscope), should be performed by a neurosurgeon with extensive experience in pituitary surgery, in order to maximize the chances of complete resection and to minimize complications. If a tumor remnant persists, watchful waiting is preferred to routine radiotherapy, as long as the tumor residue does not grow and is distant from the optic pathways. NFPA can sometimes recur even after complete resection, but predicting the individual risk of tumor remnant progression is difficult. Postoperative irradiation is only considered in case of residual tumor growth or relapse, due to its potential side effects.

Not All Kirsten Rat Sarcoma Viral Oncogene Homolog Mutations Predict Poor Survival in Patients With Unresectable Colorectal Liver Metastasis.

Objective: To assess the characteristics of Kirsten rat sarcoma viral oncogene homolog (KRAS) mutations and investigated whether all KRAS mutations predict poor prognosis in patients with unresectable colorectal liver metastasis (CRLM). Methods: Correlations between KRAS-mutation status and clinicopathological characteristics of 93 patients with unresectable CRLM at our institution between 2010 and 2018 were retrospectively analyzed. Kaplan-Meier and Cox proportional hazard models were used to evaluate the prognostic significance of KRAS mutations. Results:KRAS were primarily single-point mutations, identified in 41.9% of patients. There were no significant differences in clinicopathological characteristics between wild-type KRAS and mutant KRAS. Patients with mutant KRAS had significantly worse overall survival (OS) and progression-free survival (PFS) than those with wild-type KRAS. Moreover, patients with codon 12 mutations had worse OS and PFS than those with wild-type KRAS, whereas mutations in codon 13 were not associated with a worse prognosis. Among the 5 most common mutations in codons 12, G12V, and G12D were associated with worse OS, furthermore, G12C mutation seemed to associated with worse PFS than patients with wild-type KRAS. Conclusion:KRAS codon 12 mutations were predictive for a poor prognosis in patients with unresectable CRLM. G12D and G12V mutations were associated with worse OS, whereas G12C mutation seemed to be associated with decreased PFS.

Transvaginal natural orifice specimen extraction surgery (NOSES) in 3D laparoscopic partial or radical nephrectomy: a preliminary study.

BACKGROUND: With the development of minimally invasive technology, more and more people pay attention to aesthetics of the wound after operation. This study is aim to introduce a new surgical technique of transvaginal natural orifice specimen extraction surgery (NOSES) in 3D laparoscopic partial or radical nephrectomy and evaluate the safety, feasibility and clinical effect. METHODS: Eleven patients who underwent 3D laparoscopic partial nephrectomy (n = 7) or radical nephrectomy (n = 4) and NOSES were included in this study. The surgical procedures and techniques, especially the NOSES operation, are reported in detail. In addition, the basic clinical data, perioperative related data, perioperative complications were analyzed. RESULTS: All 11 patients were performed successfully without conversion to open surgery. The mean total operative time was 133 (84, 150) min. NOSES time was 15 (13, 16) min, and the postoperative hospital stay was 5 (5, 5) d. The mean visual analogue score (VAS) was 3 (2, 4) point and 1 (0, 1) point at 24 h and 48 h after operation, respectively. No patient had recurrence, metastasis and death during the follow-up period of 3 to 17 months. The median Vancouver Scar Scale (VSS) was 1 (1, 1) point. The mean of Female Sexual Function Index (FSFI) was 21.60 (20.20, 21.60), 21.80 (19.80, 21.80) respectively between preoperative and postoperative 3 months, which has no statistical difference (P = 0.179). There was no statistical difference in the Pelvic Floor Distress Inventory-short form 20 (PFDI-20) score between preoperative and postoperative 3 months (P = 0.142). CONCLUSIONS: Transvaginal NOSES is safe and feasible in 3D laparoscopic partial or radical nephrectomy. Furthermore, it results in low incision-related pain without affecting the pelvic floor and sexual function.

Recommendations regarding cardiac stereotactic body radiotherapy for treatment refractory ventricular tachycardia.

BACKGROUND: Ventricular tachycardia (VT) is a potentially lethal complication of structural heart disease. Despite optimal management, a subgroup of patients continue to suffer from recurrent VT. Recently, cardiac stereotactic body radiotherapy (CSBRT) has been introduced as a treatment option in patients with VT refractory to antiarrhythmic drugs and catheter ablation. OBJECTIVE: The purpose of this study was to establish an expert consensus regarding the conduct and use of CSBRT for refractory VT. METHODS: We conducted a modified Delphi process. Thirteen experts from institutions from Germany and Switzerland participated in the modified Delphi process. Statements regarding the following topics were generated: treatment setting, institutional expertise and technical requirements, patient selection, target volume definition, and monitoring during and after CSBRT. Agreement was rated on a 5-point Likert scale. The strength of agreement was classified as strong agreement (≥80%), moderate agreement (≥66%) or no agreement (<66%). RESULTS: There was strong agreement regarding the experimental status of the procedure and the preference for treatment in clinical trials. CSBRT should be conducted at specialized centers with a strong expertise in the management of patients with ventricular arrhythmias and in stereotactic body radiotherapy for moving targets. CSBRT should be restricted to patients with refractory VT with optimal antiarrhythmic medication who underwent prior catheter ablation or have contraindications. Target volume delineation for CSBRT is complex. Therefore, interdisciplinary processes that should include cardiology/electrophysiology and radiation oncology as well as medical physics, radiology, and nuclear medicine are needed. Optimal follow-up is required. CONCLUSION: Prospective trials and pooled registries are needed to gain further insight into this promising treatment option for patients with refractory VT.
