ABSTRACT

BACKGROUND: Patients who have undergone the Fontan procedure are at risk of developing hepatic dysfunction. However, broad recommendations regarding liver monitoring are limited. The purpose of this study was to characterize the frequency of liver disease in adult Fontan patients using multimodality imaging (hepatic magnetic resonance imaging [MRI], acoustic radiation force impulse [ARFI] elastography, or hepatic ultrasound). METHODS: In a prospective cross-sectional analysis of adult patients palliated with a Fontan procedure, hepatic MRI, ARFI, and hepatic ultrasound were used to assess for liver disease. The protocol compared (1) varying prevalence of liver disease based on each imaging technique, (2) agreement between different techniques, and (3) association between noninvasive imaging diagnosis of liver disease and clinical variables, including specific liver disease biomarkers. RESULTS: Thirty-seven patients were enrolled. The ARFI results showed high wave propagation velocity in 35 patients (94.6%). All patients had some abnormality in the hepatic MRI. Specifically, 8 patients (21.6%) showed signs of chronic liver disease, 10 patients (27%) had significant liver fibrosis, and 27 patients (73%) had congestion. No correlation was found between liver stiffness measured as propagation velocity and hepatic MRI findings. Only 7 patients had an abnormal hepatic ultrasound study. CONCLUSIONS: There is an inherent liver injury in adult Fontan patients. Signs of liver disease were observed in most patients by both hepatic MRI and ARFI elastography but not by ultrasound imaging. Increased liver stiffness did not identify specific disease patterns from MRI, supporting the need for multimodality imaging to characterize liver disease in Fontan patients.

ABSTRACT

Introduction. Artifactual variations in the ST segment may lead to confusion with acute coronary syndromes. Objective. To evaluate how the technical characteristics of the recording mode may distort the ST segment. Material and Method. We made a series of electrocardiograms using different filter configurations in 45 asymptomatic patients. A spectral analysis of the electrocardiograms was made by discrete Fourier transforms, and an accurate recomposition of the ECG signal was obtained from the addition of successive harmonics. Digital high-pass filters of 0.05 and 0.5 Hz were used, and the resulting shapes were compared with the originals. Results. In 42 patients (93%) clinically significant alterations in ST segment level were detected. These changes were only seen in "real time mode" with high-pass filter of 0.5 Hz. Conclusions. Interpretation of the ST segment in "real time mode" should only be carried out using high-pass filters of 0.05 Hz.

ABSTRACT

Describimos el caso de una mujer joven seguida en la consulta de Neurología por episodios de vértigo, pérdida de campo visual y síncopes. La batería de pruebas analíticas solicitada resultó anodina, descartándose un substrato trombofílico. Las pruebas de imagen pusieron de manifiesto la presencia de lesiones isquémicas occipitales de probable origen microembólico o vasculítico. Ante la repetición de nuevos episodios neurológicos focales se practicó una ecocardiografía transtorácica seguida de un ETE. Esta última constató la presencia de una masa valvular aórtica asociada a regurgitación significativa. Analizando las características ecocardiográficas de la masa, así como el contexto clínico de la paciente, se llegó al diagnóstico de probable fibroelastoma papilar aórtico y se pautó anticoagulación oral. Un año más tarde hemos comprobado la desaparición de la masa valvular aórtica así como la disminución del grado de regurgitación (AU)

ABSTRACT

Patients undergoing cardiac transplantation are at increased risk of dyslipidemia (60% to 80%). Lipid-lowering treatment in these patients should be aggressive given the known role of dyslipidemia in chronic transplant rejection. The objective of this study was to evaluate the efficacy and safety of pravastatina therapy and its effect upon cyclosporine levels in a population of dyslipidemic cardiac transplant patients.A total of 20 cardiac transplant patients were enrolled in this 39-week length prospective observational study. Patients had serum cholesterol levels exceeding 200 mg/dl, and received pravastatin therapy at the adequate dose to obtain an optimal lipid profile without significant adverse effects. Pravastatin, at a mean dose of 50 18 mg/day, produced a significant reduction in total cholesterol levels (from 291 32 to 203 25 mg/dl, p < 0.05), LDL cholesterol (from 187 34 to 102 15 mg/dl, p < 0.05) and an increase in HDL-cholesterol levels (from 48 16 to 55 14, p < 0.05). A slight asymptomatic increase in CPK levels was observed but no differences in cyclosporine levels. Pravastatin has shown to be an effective and safe therapy in dyslipidemic cardiac transplant patients.

ABSTRACT

Los pacientes sometidos a trasplante cardíaco tienen un mayor riesgo de dislipidemia (60 por ciento-80 por ciento).Debido al conocido papel de la dislipidemia en el desarrollo de enfermedad vascular del injerto, el tratamiento hipolipidemiante debería ser especialmente agresivo en estos pacientes. El objetivo de este estudio ha sido evaluar la eficacia y seguridad del tratamiento con pravastatina y su efecto sobre los niveles de ciclosporina sobre una población de pacientes trasplantados dislipidémicos.Incluimos, en este estudio prospectivo observacional de 39 semanas de duración, a 20 pacientes trasplantados cardíacos con cifras de colesterol basales por encima de 200 mg/dl, que recibieron tratamiento con pravastatina a la dosis necesaria para alcanzar un óptimo perfil lipídico o aparición de efectos adversos significativos. Pravastatina, a una dosis media de 50 ñ 18 mg/día, produjo una reducción significativa de los niveles de colesterol (de 291 ñ 32 a 203 ñ 25 mg/dl, p < 0,05), colesterol LDL (de 187 ñ 34 a 102 ñ 15 mg/dl, p < 0,05) e incrementó el colesterol HDL (de 48 ñ 16 a 55 ñ 14, p < 0,05).Observamos un ligero incremento de las cifras de creatinfosfocinasa (CPK) asintomático y sin mayor relevancia clínica, y los niveles de ciclosporina no experimentaron diferencias significativas.La pravastatina se ha mostrado en nuestro estudio como un tratamiento seguro y eficaz en pacientes trasplantados cardíacos con dislipidemia (AU)

ABSTRACT

Objetivo. El propósito de este estudio fue analizar el efecto del fosinopril sobre la presión arterial, perfil lipídico, función renal, hepática y masa ventricular en pacientes con hipertensión ligera o moderada. Material y método. Se incluyeron 24 pacientes de 66ñ8 años, 14 mujeres y 10 varones, 16 con hipertensión arterial aislada y 8 asociada a cardiopatía isquémica. Medicación concomitante: aspirina 9; nitratos 8; bloqueadores beta 5; antidiabéticos orales 4; hipolipidemiantes 4; calcioantagonistas 3; diuréticos 3 y ranitidina 2 pacientes. Esta medicación no se modificó a lo largo del estudio. Se incluyeron pacientes consecutivos y estables diagnosticados de hipertensión arterial esencial. Se realizaron controles a la semana de retirar la medicación antihipertensiva (revisión 1), semanas 4 (revisión 2), 12 (revisión 3) y tras 7 días de retirar el fosinopril (revisión 4).Resultados. Hubo diferencias significativas (p<0,05) en la presión arterial sistólica y diastólica al comparar el valor basal (PAS: 159ñ11 mmHg; PAD: 99ñ8 mmHg) y a las 4 (PAS: 137ñ10 mmHg; PAD: 82ñ7 mmHg) y 12 semanas (PAS: 136ñ12; PAD: 85ñ8, incluso tras retirar el fármaco (PAS: 151ñ12 mmHg; PAD: 96ñ10 mmHg). No hubo cambios en los triglicéridos, colesterol total ni colesterol HDL. Tampoco en los parámetros de función hepática y renal. Se encontró un descenso significativo en el colesterol LDL a las 12 semanas (132ñ9 frente a 141ñ12) y tras la suspensión del fármaco (133ñ12 frente a 141ñ12). La Lp(a) mostró cambios significativos, con respecto al basal, en todas las revisiones (revisión 2: 5ñ22 frente a 8ñ23; revisión 3: 4ñ22 frente a 8ñ23) aunque experimentó un efecto rebote al retirar el fosinopril (10ñ21 frente a 8ñ23). No se apreciaron cambios en los parámetros de función diastólica ni en la fracción de eyección; no obstante, la masa ventricular sí experimentó un descenso significativo 253ñ58 frente a 276ñ59). Conclusiones. Según estos resultados, creemos que el fosinopril debe ser considerado un fármaco de primera línea en el tratamiento de la hipertensión arterial. Es capaz, por un lado, de reducir la masa ventricular y, por otro, de mejorar de forma significativa el perfil lipídico del paciente sin producir alteraciones en la función hepática o renal (AU)

ABSTRACT

Early infectious endocarditis occurs in 3% of prostheses in the first 12 months after valvular surgery and is more aggressive than late prosthetic endocarditis. Mortality remains high, especially in early cases, despite combined medical and surgical treatment. Clinical manifestations of early cases are due to both bacteremia and prosthetic malfunction, and is mainly caused by staphylococci. We present a case report of early prosthetic endocarditis in aortic prostheses complicated with severe aortic regurgitation and right atria-aortic root fistula with auriculoventricular and intraventricular disturbance in electrocardiogram.
