RESUMO
We present the case of a 71-year-old woman with rheumatic valvular disease who underwent mitro-aortic mechanical valve replacement and tricuspid annuloplasty in 2011. She required a dual-chamber pacemaker in 2012 and developed severe tricuspid regurgitation (TR), leading to percutaneous annuloplasty with Cardioband® system in 2021.
RESUMO
BACKGROUND: Incomplete treatment of congestion often leads to worsening heart failure (HF). The remote dielectric sensing (ReDS) system is an electromagnetic energy-based technology that accurately quantifies changes in lung fluid concentration noninvasively. OBJECTIVES: This study sought to assess whether an ReDS-guided strategy during acutely decompensated HF hospitalization is superior to routine care for improving outcomes at 1 month postdischarge. METHODS: ReDS-SAFE HF (Use of ReDS for a SAFE discharge in patients with acute Heart Failure) was an investigator-initiated, multicenter, single-blind, randomized, proof-of-concept trial in which 100 patients were randomized to a routine care strategy, with discharge criteria based on current clinical practice, or an ReDS-guided decongestion strategy, with discharge criteria requiring an ReDS value of ≤35%. ReDS measurements were performed daily and at a 7-day follow-up visit, with patients and treating physicians in the routine care arm blinded to the results. The primary outcome was a composite of unplanned visits for HF, HF rehospitalization, or death at 1 month after discharge. RESULTS: The mean age was 67 ± 14 years, and 74% were male. On admission, left ventricular ejection fraction was 37% ± 16%, and B-type natriuretic peptide was 940 pg/L (Q1-Q3: 529-1,665 pg/L). The primary endpoint occurred in 10 (20%) patients in the routine care group and 1 (2%) in the ReDS-guided strategy group (log-rank P = 0.005). The ReDS-guided strategy group experienced a lower event rate, with an HR of 0.094 (95% CI: 0.012-0.731; P = 0.003), and a number of patients needed to treat of 6 to avoid an event (95% CI: 3-17), mainly resulting from a decrease in HF readmissions. The median length of stay was 2 days longer in the ReDS-guided group vs the routine care group (8 vs 6; P = 0.203). CONCLUSIONS: A ReDS-guided strategy to treat congestion improved 1-month prognosis postdischarge in this proof-of-concept study, mainly because of a decrease of the number of HF readmissions.

AIMS: Right ventricular (RV) performance determines clinical management in severe tricuspid regurgitation (TR). Right atrial (RA) function complements RV assessment in TR. This study aimed to design a novel index by speckle-tracking echocardiography (STREI index) integrating RA and RV strain information and to evaluate the clinical utility of combining RV and RA strain for prediction of cardiovascular (CV) outcomes. METHODS AND RESULTS: Consecutive patients with at least (≥) severe TR evaluated in the Heart Valve Clinic (n = 300) were prospectively included. An additional independent TR cohort was included for external validation (n = 50). STREI index was developed with the formula: [2 ∗ RV-free wall longitudinal strain (RV-FWLS)] + reservoir RA strain (RASr). The composite endpoint included hospital admission due to heart failure and all-cause mortality. A total of 176 patients with ≥severe TR were finally included. STREI index identified a higher percentage of patients with RV dysfunction compared with conventional parameters. After a median follow-up of 2.2 years (interquartile range: 12-41 months), a total of 38% reached the composite endpoint. STREI values were predictors of outcomes independently of TR severity and RV dimensions. The combination of prognostic cut-off values of RASr (<10%) and RV-FWLS (>-20%) (STREI stratification) stratified four different groups of risk independently of TR severity, RV dimensions, and clinical status (adj HR per stratum 1.89 (1.4-2.34), P < 0.001). Pre-defined cut-off values achieved similar prognostic performance in the validation cohort (n = 50). CONCLUSION: STREI index is a novel parameter of RV performance that independently predicts CV events. The combination of RA and RV strain stratifies better patients' risk, reflecting a broader effect of TR on right heart chambers.

Introducción y objetivos: La insuficiencia tricuspídea (IT) significativa se asocia con un aumento de la morbimortalidad. La valoración clínica del paciente con IT es un reto. Nuestro objetivo es establecer una nueva clasificación clínica, específica para pacientes con IT, denominada clasificación 4A, y evaluar su impacto pronóstico. Métodos: Se incluyó a pacientes evaluados en la clínica valvular, con IT aislada al menos grave y ausencia de antecedentes de insuficiencia cardiaca (IC). Se recogieron síntomas y signos de astenia, edema en extremidades inferiores, dolor o distensión abdominal y anorexia (asthenia, ankle swelling, abdominal pain or distention and anorexia) y se realizó un seguimiento cada 6 meses. La clasificación 4A abarca desde A0 (ninguna A) a A3 (3 o 4 Aes). Se definió un resultado combinado de ingreso hospitalario debido a IC derecha o muerte de causa cardiovascular. Resultados: Se incluyó a 135 pacientes con IT significativa entre 2016 y 2021 (el 69% mujeres; media de edad, 78±7 años). Durante un seguimiento medio de 26 [intervalo intercuartílico, 10-41] meses, 53 pacientes (39%) alcanzaron el resultado combinado. Ingresaron por IC 46 (34%) y murió un 5% (n=7). Al inicio, el 94% de los pacientes se encontraban en NYHA I o II, mientras que el 24% ya presentaba A2 o A3. La presencia de A2 o A3 se asoció con una alta incidencia de eventos. El cambio en la puntuación de la clasificación 4A fue un marcador independiente de IC y muerte cardiovascular (HR ajustada por unidad de cambio de la clasificación 4A=1,95 [1,37-2,77]; p <0,001). Conclusiones: Se muestra una nueva clasificación clínica específica para pacientes con IT basada en signos y síntomas de IC derecha y predictora de eventos.
Introduction and objectives: Significant tricuspid regurgitation (TR) is associated with increased morbidity and mortality. Clinical evaluation of TR patients is challenging. Our aim was to establish a new clinical classification specific for patients with TR, the 4A classification, and evaluate its prognostic performance. Methods: We included patients with isolated TR that was at least severe and without previous episodes of heart failure (HF) who were assessed in the heart valve clinic. We registered signs and symptoms of asthenia, ankle swelling, abdominal pain or distention and/or anorexia and followed up the patients every 6 months. The 4A classification ranged from A0 (no A) to A3 (3 or 4 As present). We defined a combined endpoint consisting of hospital admission due to right HF or cardiovascular mortality. Results: We included 135 patients with significant TR between 2016 and 2021 (69% females, mean age 78±7 years). During a median follow-up of 26 [IQR, 10-41] months, 39% (n=53) patients had the combined endpoint: 34% (n=46) were admitted for HF and 5% (n=7) died. At baseline, 94% of the patients were in NYHA I or II, while 24% were in classes A2 or A3. The presence of A2 or A3 conferred a high incidence of events. The change in 4A class remained an independent marker of HF and cardiovascular mortality (adjusted HR per unit of change of 4A class, 1.95 [1.37-2.77]; P<.001). Conclusions: This study reports a novel clinical classification specifically for patients with TR that is based on signs and symptoms of right HF and has prognostic value for events.(AU)

AIMS: The optimal management of severe tricuspid regurgitation (TR) remains controversial. While right ventricular systolic function is an established prognostic marker of outcomes, the potential role of right atrial (RA) function is unknown. This study aimed to describe RA function by 2D speckle-tracking echocardiography (STE) in at least severe TR and to evaluate its potential association with cardiovascular outcomes. METHODS AND RESULTS: Consecutive patients with at least (≥) severe TR (severe, massive, or torrential TR) evaluated in the Heart Valve Clinic following a comprehensive clinical protocol were included. Consecutive control subjects and patients with permanent isolated atrial fibrillation (AF) were included for comparison (control and AF group, respectively). RA function was measured with 2D-STE and two components of RA function were calculated: reservoir (RASr) and contractile (RASct) strain (AutoStrain, Philips Medical Systems the EPIQ system). A combined endpoint of hospital admission due to heart failure (HF) or all-cause mortality was defined. Patients with ≥ severe TR (n = 140) showed lower RASr compared with controls (n = 20) and with the AF group (n = 20) (P < 0.001). Atrial TR showed lower RASr compared with other aetiologies of TR (P < 0.001). After a median follow-up of 2.2 years (IQR: 12-41 months), RASr remained an independent predictor of mortality and HF. A cut-off value of RASr of <9.4% held the best accuracy to predict outcomes. CONCLUSION: RA function by 2D-STE independently predicts mortality and HF hospitalizations in patients with ≥ severe TR.

INTRODUCTION: Assuming that spinal shape is a genetic expression, its analysis and acquired factors could assess their respective contribution to early spine deterioration. MATERIAL AND METHODS: A geometric morphometric analysis was retrospectively performed on sagittal lumbar MRI of young patients with back pain to identify lumbar spine shape changes. Using Geometric Morphometrics, findings were analyzed with anthropometric, radiological, and clinical variables. RESULTS: 80 cases under 26 years of age were collected, 55 men (mean age 22.81) and 25 women (mean age 23.24). MRI abnormalities were reported in 57.5%: single altered disc (N=17), root compromises (N=8), and transition anomalies (35%).In the non-normal MRI subgroup, shape variation included: increased lordosis, enlarged vertebral body, canal stenosis, and lumbarization of S1. In non-Spanish origin patients, lumbar straightening and segmental deformities were prevalent. Morphometrics findings showed that lumbosacral transition anomalies are frequently underreported. CONCLUSIONS: Genetic factors could be the main determinants of abnormality in MRIs under 26 years. The primary markers are transitional abnormalities, segmental deformities, and canal stenosis. In foreign populations, shape changes could suggest spine overload at an early age.
RESUMO
Objetivo Evaluar la relación del resultado del test Oncotype DX en tumores luminales con el valor del coeficiente de difusión aparente (CDA) en la secuencia de difusión en resonancia magnética (RM) mamaria y con otros parámetros radiológicos y anatomopatológicos. Pacientes y método Se revisaron retrospectivamente las RM mamarias de estadificación de las pacientes con cáncer de mama (CM) con receptores de estrógenos (RE) positivos y HER2 negativo a las que se les había solicitado el test Oncotype DX en los últimos cuatro años. Se recogieron los antecedentes familiares y personales, el tamaño y tipo de realce de la lesión, el CDA, el porcentaje de restricción a la difusión y la anatomía patológica. Todo ello se relacionó con el riesgo de recidiva (bajo: < 18, intermedio: 18-30 y alto: > 30) estimado en el test Oncotype DX. Resultados Se incluyeron 70 pacientes. Las lesiones categorizadas como bajo riesgo de recidiva asociaron valores de CDA significativamente más altos que el resto de grupos (p = 0,04) y las clasificadas como alto riesgo menor expresión de receptores de progesterona (RP) (p = 0,038). El valor de CDA clasificó como riesgo bajo o intermedio-alto según Oncotype DX con un área bajo la curva (AUC) de 0,73 (p = 0,001) para todos los tumores y de 0,76 (p < 0,001) en lesiones con RP positivos. Conclusiones Se encontraron valores más altos del CDA en el grupo clasificado como riesgo bajo de recidiva y menor expresión de RP en el grupo de riesgo alto. El CDA podría ser útil en el pronóstico del CM, aunque son necesarios más estudios. (AU)
Objective To assess the relationship of the Oncotype DX test result with the apparent diffusion coefficient (ADC) value in the diffusion sequence in breast magnetic resonance imaging (MRI) and with other radiological and anatomical-pathological parameters. Patients and methods We reviewed the pre-surgical staging breast MRIs of breast cancer (BC) patients with positive oestrogen receptors (ER) and negative HER2, for which the Oncotype DX test had been requested over the last four years. The ADC and the diffusion restriction percentage were obtained. Personal and family background were collected, along with pathological anatomy findings. We determined the association between all these factors and the risk of recurrence (low: < 18, intermediate: 18-30 and high: > 30) estimated by the Oncotype DX test. Results A total of 70 patients were included. Lesions categorized as being at low risk of recurrence according to the Oncotype DX test were associated with significantly higher ADC values than the rest of the groups (p = 0.04), and those classified as high risk were associated with lower progesterone receptor (PR) expression (p = 0.038). The ADC value classified the risk as low or intermediate-high according to the Oncotype DX test with an area under the curve (AUC) of 0.73 (p = 0.001) for all tumours and 0.76 (p < 0.001) in lesions with positive PR. Conclusions Higher ADC values were found in the group classified as being at low risk of tumour recurrence according to Oncotype DX. Lesions with high risk scores expressed lower PR. The ADC value may be useful in the prognosis of breast cancer, although further studies are required. (AU)

La vertebroplastia y la cifoplastia son procedimientos de punción percutáneos que precisan de la inyección de cemento en el soma de una vértebra fracturada, con el fin de refuerzo y alivio del dolor. Con ocasión de un caso de cifoplastia del soma de L2 que desarrolló una infrecuente embolización diferida de cemento a la arteria pulmonar, se revisa la literatura y analizan los principales problemas médico-legales de estas complicaciones. Se subraya la necesidad de un consentimiento informado detallando la frecuencia y riesgos de estas complicaciones, así como un adecuado control radiológico postoperatorio, no solo local, sino torácico. Igualmente, se enfatiza la posibilidad de repetir el estudio radiológico local y torácico, ante cualquier cambio de la morfología de la fuga local o desaparición de la fuga local, ante la posibilidad de migraciones tardías. (AU)
Vertebroplasty and kyphoplasty are percutaneous puncture procedures that require the injection of cement into the soma of a fractured vertebra for reinforcement and pain relief.As the result of a case of kyphoplasty of the soma of L2 that developed a rare, delayed embolization of cement to the pulmonary artery, we undertook a literature review, and the main medico-legal problems of these complications were analysed.The need for informed consent is stressed, detailing the frequency and risks of these complications, as well as adequate postoperative local and chest X-ray control. Likewise, the possibility is highlighted of repeat local and chest X-rays in the event of any change in the morphology of local leakage or disappearance of local leakage in the event of late migration.

OBJETIVO: Los tumores triples negativos (TN) constituyen el subgrupo de cáncer de mama (CM) más agresivo. Nuestro objetivo es analizar los principales factores radiopatológicos de estos tumores para crear un perfil de riesgo. MATERIALES Y MÉTODOS: Es un estudio constituido por 140 pacientes diagnosticadas de CM TN desde enero del 2007 a diciembre del 2016. Se analizaron los factores radiológicos en resonancia magnética (RM) de estadificación: tamaño, necrosis, hallazgos asociados, adenopatías, parámetros de perfusión y difusión. En biopsias diagnósticas se estudiaron características del componente infiltrante: tipo histológico, Scarf-Bloom, Ki67 y p53 y el componente in situ. Se analizaron las adenopatías histológicamente positivas y en las piezas quirúrgicas: tamaño, invasión linfovascular/perineural y adenosis microglandular. El seguimiento finalizó en abril de 2018. Se evaluó la relación de los factores radiopatológicos con la recidiva y la supervivencia libre de enfermedad (SLE). RESULTADOS: Los tumores con tamaño igual o superior a 25 mm en RM, realce no nodular, edema mamario o retracción del complejo aréola-pezón y adenopatías presentaron más recidivas y menor SLE. Los carcinomas lobulillares infiltrantes, el tamaño posquirúrgico>20 mm y p53 <15% también se asociaron con la recidiva y una menor SLE. Las adenopatías histológicamente positivas se relacionaron con un mayor porcentaje de recidivas, y la invasión linfovascular, con una menor SLE. El análisis multivariante ha definido que el tamaño en RM>25 mm, el realce no nodular, las adenopatías en RM, y la expresión menor del 15% de p53 son variables pronósticas independientes. CONCLUSIONES: El tamaño igual o superior a 25 mm, realce no nodular y adenopatías en RM, y una expresión inferior al 15% de p53 condicionan una menor SLE
OBJECTIVE: Triple-negative tumors are the most aggressive type of breast cancer. We aimed to analyze the main radiologic and histopathologic factors of these tumors to create a risk profile. MATERIALS AND METHODS: We analyzed data from 140 patients diagnosed with triple-negative breast cancer between January 2007 and December 2016, with follow-up through April 2018. We analyzed the following variables in the breast MRI done for staging: size, necrosis, associated findings, adenopathies, and perfusion and diffusion parameters. We analyzed the following variables in histopathologic studies of biopsy specimens: histological type, Scarf-Bloom, Ki67, and p53 in the infiltrating component as well as in the in situ component. We analyzed the following variables in histopathologic studies of positive lymph nodes and surgical specimens: size, lymphovascular/perineural invasion, and microglandular adenosis. We analyzed the relation between the radiologic and histopathologic factors and recurrence and disease-free survival. RESULTS: MRI tumor size>25mm, non-nodular enhancement, breast edema, areola-nipple complex retraction, and lymph-node involvement were associated with recurrence and lower disease-free survival. Invasive lobular carcinoma, postsurgical size>20mm, and p53<15% were also associated with recurrence and lower disease-free survival. Histologically positive lymph nodes were associated with a greater percentage of recurrence and lymphovascular invasion and with lower disease-free survival. The multivariate analysis found that the variables MRI size>25mm, non-nodular enhancement, adenopathies on MRI, and p53 expression <15% were independent predictors of lower disease-free survival. CONCLUSIONS: In triple-negative breast tumors, factors associated with lower disease-free survival are non-nodular enhancement, size>25mm, and adenopathies on MRI, and p53 expression <15% on histopathologic study

Poly-ether-ether-ketone (PEEK) cages have lower modulus of elasticity when compared with Titanium (TTN) cages. This suggests that PEEK-cages could show a lower rate of subsidence after anterior cervical discectomy-fusion (ACDF) and might lead to a lower loss of correction. We investigated the one to five year-results of standalone PEEK-TTN-porous coated cages in a patient cohort from 2014 to 2017. The patients underwent single-level ACDF for disc herniation and degenerative discopathy. Clinical and radiological outcome were assessed in 50 eligible patients after a mean of 27 months. Results: Solid arthrodesis was found in 84%. Neck disability index (NDI), and visual analogue scale (VAS) of neck and arm show comparable results to the literature. Conclusions: Clinical and radiological outcomes of ACDF with PEEK-body-cages with a porous coated surface show good bony integration. The modulus of elasticity, design, shape, size, cage surface architecture, as well as bone density, endplate preparation, radical microdiscectomy and distraction during surgery should be considered as important factors influencing the clinical results. One main advantage, over titanium cages, is the absence of MRI artifacts, allowing an excellent postoperative follow-up.

La donación corporal es la base de los programas de trasplantes, cuya regulación se fundamenta en los derechos del donante y receptor. Sin embargo, si su objetivo no es asistencial, la normativa difiere tanto en vivos como en fallecidos. Las llamadas «técnicas de imagen» permiten obtener ficheros digitales con el cuerpo virtual del paciente, lo que brinda una nueva posibilidad: la donación corporal virtual, no regulada en España y tampoco ajustada a la normativa del resto de las donaciones. Presentamos un programa de donación corporal, analizando sus características, aspectos médico-legales, clínicos, de organización y funcionamiento. Contar con un número ilimitado de especímenes virtuales impulsa una nueva forma de docencia e investigación. Tiene, además, ventajas para la formación de los profesionales en técnicas de autopsia virtual. Creemos que este programa, pionero en España, puede servir para extender iniciativas similares de utilidad ilimitada en docencia e investigación en ciencias forenses, morfológicas y afines
Body donation is in the basis of transplantation programs, founded on receptor and donor rights. Nevertheless, if the purpose is not directed to healthcare, the regulation is different both in live or deceased individuals. "Imaging techniques" generates digital files containing the «virtual body» of the patient, raising a new possibility: virtual body donation, which is not regulated in Spain and would not be compliant with legal requirements for other ways of donation. A pioneer program for virtual body donation is presented, analysing its characteristics, medico-legal issues, organisation and functioning. Having an unlimited number of virtual specimens (normal and pathological) could support a new way for teaching and research. These resources would also have the advantage of learning virtual biopsy (virtopsy). It is thought that these programs, pioneers in Spain, could be useful for introducing similar initiatives that would have unlimited applications in teaching and research both in forensic and morphological sciences

The time interval between the date of trauma and the diagnosis of vertebral column fractures hinders management and increases liability. We have examined the features and implications of this delay. 585 consecutive thoracolumbar fractures (2005-2016), were considered; 382 (65.30%) were males and 203 (34.70%) females. Mean age was 51 yr. Fall from a height (187; 31.97%), simple fall (147; 25.13%) and road accidents (111; 18.97%) were the most frequent causes of trauma. Physical exertion caused 8.38% (N=49). 142 patients (24.27%) were not diagnosed on the injury day (mean = 3.2 days). Delay was longer in females (mean = 5.5 vs. 2.7 days) and shorter in falls from a height (mean = 2.3) or road accidents (2.8). Mean age of diagnosed on the injury day differed from those diagnosed in the first month (49.2 vs 60.1). Plain X-ray signs were found in 7 misdiagnosed cases (46.6%). Delay was more frequent in low mineralization cases. Diagnostic delay of spine fractures is frequent. Some risk profiles can help to reduce it. Careful emergency X-ray examination is encouraged, as well as early magnetic resonance imaging in risk profiles.
