RESUMEN

The role of cardiac implantable electronic device (CIED)-related tricuspid regurgitation (TR) is increasingly recognized as an independent clinical entity. Hence, interventional TR treatment options continuously evolve, surgical risk assessment and peri-operative care improve the management of CIED-related TR, and the role of lead extraction is of high interest. Furthermore, novel surgical and interventional tricuspid valve treatment options are increasingly applied to patients suffering from TR associated with or related to CIEDs. This multidisciplinary review article developed with electrophysiologists, interventional cardiologists, imaging specialists, and cardiac surgeons aims to give an overview of the mechanisms of disease, diagnostics, and proposes treatment algorithms of patients suffering from TR associated with CIED lead(s) or leadless pacemakers.

RESUMEN

Myocarditis is defined as myocardial inflammation and its etiology is highly diverse, including infectious agents, drugs, and autoimmune diseases. The clinical presentation also varies widely, extending beyond the classic clinical picture of acute chest pain, and includes cases of cardiomyopathy of unknown cause whose etiology may be inflammatory. Because certain patients may benefit from targeted treatments, the search for the etiology should begin when myocarditis is first suspected. There remain several areas of uncertainty in the diagnosis and treatment of this disease. Consequently, this consensus document aims to provide clear recommendations for its diagnosis and treatment. Hence, a diagnostic algorithm is proposed, specifying when non-invasive diagnosis with cardiac MR is appropriate vs a noninvasive approach with endomyocardial biopsy. In addition, more novel aspects are discussed, such as when to suspect an underlying genetic etiology. The recommendations cover the management of myocarditis and inflammatory cardiomyopathy, both for general complications and specific clinical entities.

RESUMEN

INTRODUCTION AND OBJECTIVES: In patients with tricuspid regurgitation (TR), edge-to-edge transcatheter tricuspid valve repair (TTVR) is the strategy with the highest penetration worldwide. A dedicated edge-to-edge TTVR system has recently become available in Europe. The present study describes the initial experience with the system in Spain. METHODS: This multicenter study collected individual data from the centers accepted for the use of the novel system within an initial limited release. Between June 2020 and March 2021, all patients undergoing an edge-to-edge TTVR using the TriClip system in Spain were included in the study. The primary endpoint was the achievement of a TR reduction of at least 1 grade at discharge. RESULTS: We included 34 patients. Most of them reported a previous history of atrial fibrillation (91%) and only 1 had a pacemaker lead. The primary endpoint (TR reduction of at least 1 grade at discharge) was met in all patients. Most of the patients required 1 (47%) or 2 clips (44%) with a clear predominance of XT (87%) over NT (13%). The location of the first clip was anteroseptal in >90% of the patients. Only 1 patient had a partial detachment, which was stabilized with additional clips in the same procedure. At discharge, TR severity was≤2 in 91% of patients. At 3 months, mortality was nil. Overall, 88% of patients were in New York Heart Association functional class≤2 and 80% had residual TR≤2. CONCLUSIONS: Edge-to-edge TTVR seemed to be effective and safe with a sustained TR reduction at 3 months. Further studies will be needed to confirm our findings.

RESUMEN

BACKGROUND: Familial hypercholesterolemia (FH) confers an increased risk of premature atherosclerotic disease. Coronary computed tomographic angiography (CTA) can assess preclinical coronary atherosclerosis. OBJECTIVES: To describe coronary CTA findings in asymptomatic molecularly defined FH individuals, to identify those factors related to its presence and extension, and to assess the impact of these results in patients' care and estimated risk. METHODS: Four hundred and forty individuals with FH, without clinical cardiovascular disease, were consecutively enrolled and underwent a coronary CTA that was used to analyze coronary atherosclerosis based on coronary calcium score (CCS), sum of stenosis severity, and plaque composition sum (PCS). For FH patients, cardiovascular risk was estimated using the specific SAFEHEART risk equation. Follow-up was performed using a standardized protocol. RESULTS: Mean age was 46.4 years (231 women, 52%). Coronary calcium was present in 55%, mean CCS was 130.9, 46% had a plaque with lumen involvement, and mean PCS was 1.1. During follow-up, there were 17 (4%) nonfatal events and 2 (1%) fatal events. CCS was independently associated to the estimated risk and low-density lipoprotein-cholesterol life-years, sum of stenosis severity to the estimated risk, and PCS to the estimated risk and low-density lipoprotein-cholesterol life-years. CTA findings induced a positive change in patients' care and in their estimated risk. CONCLUSION: Coronary artery atherosclerosis is highly prevalent in asymptomatic patients with FH and it is independently associated to cardiovascular risk. More advanced disease on CTA was associated with subsequent intensification of therapy and reduction of estimated risk. Further longitudinal studies are required to know if these findings might improve the risk stratification in patients with FH.

RESUMEN

OBJECTIVES: The early prognostic evaluation of acute pancreatitis (AP) is a key step in the appropriate management of the disease. Plasma levels of polymorphonuclear elastase have proved to be an accurate early prognostic marker of AP in research conditions. Whether the test remains sufficiently accurate in routine clinical conditions has been questioned. The aim of our study was to evaluate the accuracy of plasma polymorphonuclear-elastase levels for the early prognostic evaluation of AP in the clinical setting. METHODS: A total of 224 consecutive patients with AP admitted to our Gastroenterology Department were included. A blood sample for polymorphonuclear-elastase quantification was obtained from all of them in the first morning of hospital stay, together with samples for routine haematological and biochemical analysis. Blood samples for polymorphonuclear-elastase evaluation were sent to the laboratory and managed there according to routine protocols. AP was classified as mild or severe according to the Atlanta classification, whereas polymorphonuclear-elastase results were kept blind. Results were shown as mean+/-SD and compared using Student's t-test for unrelated samples. The accuracy of the test for the prognostic evaluation of AP was calculated after drawing the corresponding receiver operator curve. RESULTS: Fifty patients (23%) suffered from severe AP. The plasma levels of polymorphonuclear elastase were 217.8+/-93.5 microg/l in patients with severe AP and 68.1+/-32.7 microg/l in those with mild disease (P<0.001). The sensitivity and specificity of the test for the detection of severe AP were 92 and 91%, respectively, for an optimal cut-off value of 110 microg/l. The positive and negative predictive values for a prevalence of severe disease of 20% were 78 and 96%, respectively. The area under the receiver operator curve was 0.956. CONCLUSION: Quantification of plasma polymorphonuclear-elastase levels is a very accurate method for the early prognostic evaluation of AP, and is easily applicable in the clinical setting.

RESUMEN

AIM: Elderly patients often remain underrepresented in clinical trials. The aim of our study was to analyze the treatment, clinical outcome and risk factors for mortality in patients aged ≥85 years with ST-segment elevation myocardial infarction (STEMI). METHODS: From 2005-2011, 102 patients aged ≥85 years with STEMI admitted to a coronary care unit were retrospectively reviewed. Clinical data, treatment and outcome were recorded. Reperfusion strategy and its influence in hospital morbidity and mortality were evaluated. Morbidity was defined as the presence of heart failure (Killip-Kimball >1), arrhythmias, mechanical complications, stroke or major bleeding. Risk factors for mortality were assessed by multivariate analysis. RESULTS: The mean age was 87.5±2.5 years (range 85-96). Therapeutic strategy on admission was: primary-angioplasty (PCI) for 33 patients (32.3%) fibrinolysis for 30 patients (29.4%) and conservative treatment for 35 patients (34.3%). In the four remaining patients, rescue angioplasty was required. A total of 29 patients (28.4%) died, and morbidity was seen in 63 patients (61.7%). The morbidity and mortality rates in the conservative treatment group (77.1% and 48.5%) were higher than that found in the reperfusion strategy group (primary-PCI and fibrinolysis; 53.7% and 17.9%; P=0.02 and P=0.002, respectively). Regarding mortality, the univariate analysis showed that heart failure on admission (P=0.0001) and previous coronary artery disease (P=0.01) were prognostic variables. Only heart failure was an independent risk factor for mortality (odds ratio=3.64, 95% CI 0.78-21.87, P<0.0001). CONCLUSIONS: Mortality and morbidity in very elderly patients with STEMI are very high, especially in those not receiving reperfusion therapies. Heart failure on admission was an independent risk factor for hospital mortality.

RESUMEN

To establish the etiology of heart failure in patients with congenital heart disease can be challenging. Multiple concomitant anomalies that can be missed after an initial diagnosis could be seen in these patients. In patients with congenital heart disease, a more accurate evaluation of cardiac morphology and left ventricular systolic function could be evaluated by recent non-invasive cardiac imaging techniques. We present a rare case where multimodal cardiac imaging was useful to establish the final diagnosis of left ventricular non-compaction associated with Ebstein's anomaly.

RESUMEN

INTRODUCTION: Primary cardiac tumors are rare entities with an autopsy frequency ranging between 0.001% and 0.3%. Our objective was to review 32 years of experience from a Spanish tertiary surgical center. METHOD: We collected data on 73 patients with a histopathological diagnosis of a primary cardiac tumor in a retrospective analysis from 1979 to 2012. Tissue samples were obtained either at surgery or from necropsy and subsequently divided into benign and malignant groups. RESULTS: Benign neoplasms accounted for 84.9% of cases. The average age at diagnosis was 61 years, and tumors were twice as frequent among women. It was an incidental finding in one quarter of patients. In symptomatic patients, the typical presentation was of cardioembolic stroke or of congestive symptoms. Myxoma (93.5%) was the most common diagnosis, typically affecting the left atrium (74.2%). Surgical resection was curative for 95% of these patients. Malignant tumors represented 15.1% of cases with an average age at diagnosis of 50 years. Over 90% of these patients were symptomatic at presentation with the cardinal symptom being heart failure. Undifferentiated sarcoma was the most frequent malignant tumor (36.4%). Less than 20% of patients were alive 1 year after diagnosis despite the treatment. CONCLUSIONS: In our study, primary cardiac tumors were insidious. The most common was left atrial myxoma in which surgical resection was considered curative. Undifferentiated sarcoma was the most frequent malignant tumor. Malignant neoplasms carried a worse prognosis with unsuccessful total excision and the presence of metastatic disease being markers of an adverse outcome.

RESUMEN

Single coronary artery arising from the right sinus of Valsalva is a rare congenital coronary anomaly. We report the case of a 77- year- old man who was referred for invasive coronary angiography with a diagnosis of a non-ST-segment elevation acute coronary syndrome of inferior-lateral location. Significant lesion was detected in the proximal segment of the right coronary artery (RCA). During the procedure, it was impossible to catheterize the left coronary ostium, being the left anterior descending filled from the RCA. Given the suspicion of agenesis of the left main, 64-multidetector computed tomography was performed which confirmed the existence of a solitary coronary ostium with a single artery arising from the right sinus of Valsalva.

RESUMEN

BACKGROUND: Infliximab has improved the management of perianal Crohn's disease, but intolerance and loss of efficacy can occur. The use of a second antibody can be less effective. OBJECTIVE: Our aim was to determine if the use of adalimumab, based on a multidisciplinary strategy, can enhance outcomes for patients with fistulizing disease and infliximab failure. MATERIAL AND METHODS: Sixteen patients with perianal disease and infliximab failure were treated with adalimumab. Complex fistulas were assessed using magnetic resonance imaging (MRI). Patients with severe conditions as determined by radiology were examined under anesthesia, and seton placement was performed when appropriate. Setons were removed when external discharge had ceased and there was no radiological evidence of fistula activity. RESULTS: Nine patients (56%) underwent MRI. Setons were inserted in seven (43%). The baseline perianal disease activity index (PDAI) decreased after 4 weeks and remained at similar levels 24 and 48 weeks after treatment. The complete response rate was 50% after four weeks and 87.5% of these patients remained in remission after 48 weeks of treatment. CONCLUSIONS: For patients with Crohn's perianal fistulas and infliximab failure, adalimumab as a multidisciplinary approach to management, using MRI to guide surgical drainage when necessary, results in a favourable response and low recurrence rate.

RESUMEN

Introducción: las hojas de Pteris vittata L (helecho) son utilizadas por la población para el tratamiento de la candidiasis y en enfermedades producidas por bacterias en la piel. Objetivo: identificar preliminarmente las familias de metabolitos secundarios presentes en las hojas de la planta y evaluar su posible actividad antimicrobiana. Métodos: se recolectaron las hojas de Pteris vittata L. El material vegetal fue lavado, desinfectado, secado y seguidamente se procedió a su pulverización. Este polvo se utilizó en la elaboración de los diferentes extractos y tintura. La tintura obtenida se concentró y se fraccionó sucesivamente con n-hexano, cloroformo y acetato de etilo. A estos extractos se les realizó el tamizaje fitoquímico, ensayos microbiológicos y cromatografía de capa fina. Resultados: las pruebas in vitro efectuadas a los extractos obtenidos a partir de la tintura 20 por ciento, demostraron que éstos presentan actividad antimicrobiana frente a Escherichia coli, Staphylococcus aureus, destacándose los resultados obtenidos frente a Candida sp para los extractos de acetato de etilo y clorofórmico. En estas fracciones están presentes en mayor proporción alcaloides y quinonas, que podrían ser los responsables de esta actividad, lo cual se corrobora con la identificación de estos metabolitos secundarios mediante la cromatografía de capa fina y el tamizaje fitoquímico realizado. Conclusiones: el estudio combinado mediante la cromatografía de capa fina y el tamizaje fitoquímico de los extractos hexánico, acetato de etilo y clorofórmico permite inferir que la actividad antimicrobiana puede deberse a la presencia de quinonas y alcaloides(AU)


Introduction: Pteris vittata L. leaves (fern) are used by people on the candidiasis treatment and some skin illnesses caused by bacteria. Objective: to identify preliminarily the secondary metabolites present in the leaves of the plant and to evaluate their possible antimicrobial activity. Methods: Pteris vittata L. leaves were collected. The plant material was washed, disinfected, dried and pulverized. The powder obtained was used to make the various extracts and the tincture. The latter was concentrated and successively fractionated with n-hexane, chloroform, and ethyl acetate. The extracts underwent phytochemical screening, microbiological assays and thin-layer chromatography. Results: in vitro tests performed in the obtained extracts from the 20 percent tincture proved that they have antimicrobial activity against Escherichia coli and Staphylococcus aureus, emphasizing the accomplished results against Candida of the ethyl and chloroform acetate extracts. Alkaloids and quinones, which are found in large proportion in the extracts, would be responsible of the above- mentioned antibacterial activity. This was corroborated by the identification of these secondary metabolites through thin-layer chromatography and phytochemical screening. Conclusions: the combined study through thin-layer chromatography and phytochemical screening of the ethyl and chloroform acetate extracts showed that the antimicrobial activity could be possible due to the alkaloids and quinones presence(AU)
