Resumen El sarcoma sinovial primario del pericardio es un tumor muy raro y de mal pronóstico y se sabe poco en cuanto al manejo terapéutico. Presentamos el caso de una paciente de 51 años a quien se le realizó resección quirúrgica incompleta, quimioterapia y radioterapia. Hasta donde sabemos, este es el primer caso de un sarcoma sinovial primario de pericardio que luego de operado se mantuvo asintomático durante 5 años hasta que en una TAC de control se le detectaron metástasis cardiacas que comprometían las cavidades derechas y con quimioterapia, la ecocardiografía demostró la reso lución completa de las mismas.

Abstract Primary pericardial synovial sarcoma is an extraor dinarily very rare tumor with a poor prognosis, and little is known about its therapeutic management. We describe the case of a 51-year-old woman patient who underwent incomplete surgical resection, chemotherapy, and radiotherapy. To the best of our knowledge, no pri mary pericardial synovial sarcoma has been described which, after surgery, remains asymptomatic for 5 years, and until a control CT scan detects cardiac metastases that compromised the lumen of the right cavities and with chemotherapy, echocardiography demonstrated complete resolution of cardiac metastases.

Subcostal right ventricular free wall strain in patients with pulmonary hypertension / Strain subcostal de la pared libre del ventriculo derecho en pacientes con hipertensión pulmonar

Abstract Right ventricular longitudinal strain (RVLS) is frequently used as a measure of right ventricular systolic function. Abnormal RV strain is associated with poor prognosis in patients with pulmonary hyper tension (PH); however, the measure is not always easy to obtain in patients with poor apical acoustic windows. Objective: This study aims to analyze the RVLS and determine if there is a difference when measured from the apical and subcostal views. Methods: In this cross-sectional study, we analyzed 22 adult outpatients (≥ 18 years old), 81% female, mean age 49.9 ± 17.3 years, with a diagnosis of PH using right heart catheterization, followed from January 2016 to January 2020. Results: RVLS measured in the RV free wall from the apical views was -15% (-19% to -10%) and subcostal views -14.5% (-18% to -11%) were highly correlated (Person's r = 0.969, p < 0.0001). Segment by segment analysis did not show significant differences either: basal four-chamber vs. sub costal view was -16.5% (-21% to -11%) vs. -15.5% (-20% to -11%), p = 0.99, mid four-chamber view vs. subcotal view was -16.5% (-21% to -12%) vs. -16.5% (-20% to -11%), p = 0.87, apical four-chamber view vs. subcostal view was -12% (-18% to -8%) vs. -13.5% (-19% to -10%), p = 0.93. Conclusion: Subcostal RVLS free wall is a feasible and accurate alternative to conventional RVLS free wall from the apical view in patients with pulmonary hypertension and could be useful in patients with poor acoustic apical four-chamber windows.

Resumen El strain longitudinal del ventrículo derecho (SLVD) permite medir la función sistólica del ventrículo derecho (VD). La disminución del strain (deformación) del VD se asocia con mal pronóstico en pacientes con hipertensión pulmonar (HP), pero no siempre es fácil de obtener en pacientes con mala ventana acústica apical. Objetivo: Este estudio tiene como objetivo analizar el SLVD y determinar si las vistas apical y subcostal son comparables. Métodos: En este estudio transversal, se incluyeron 22 pacientes adultos ambulatorios (≥18 años), 81% mujeres, edad promedio 49.9 ± 17.3 años, con diagnóstico de HP mediante cateterismo cardíaco derecho, seguidos desde enero de 2016 hasta enero de 2020. Se midió la deformación de la pared libre del ventrículo derecho desde las vistas de cuatro cámaras apical y cuatro cámaras subcostal. Resultados: El SLVD medido en la pared libre del VD desde la vista apical fue -15% (-19% a -10%) vs. -14.5% (-18% a -11%) cuando se midió desde la vista subcostal (p = 0,99). El análisis segmento por s egmento tampoco mostró diferencias significativas: el segmento basal apical vs. subcostal fue -16.5% (-21% a -11%) vs. -15.5% (-20% a -11%), p = 0.99, el segmento medio apical vs. la vista subcotal fue -16.5% (-21% a -12%) vs. a -16.5% (-20% a -11%), p = 0.87, el segmento apical vs. la vista subcostal fue -12% (-18% a -8%) frente a -13.5% (-19% a -10%), p = 0.93. Conclusión: En pacientes con HP, el SLVD obtenido en la pared libre subcostal es una alternativa útil en los casos con ventana acústica apical subóptima.

[Experience in infective endocarditis over 30 years in a hospital in Buenos Aires]. / Experiencia en endocarditis infecciosa a lo largo de 30 años en un hospital de Buenos Aires.

Infective endocarditis (IE) is a disease that in recent decades has shown changes in its presentation, diagnosis and treatment. This is a prospective study of 252 patients admitted at a reference hospital in Buenos Aires, Argentina, with a diagnosis of IE and they were grouped according to the decade of admission: Group A: from January 1988 to December 1997 (89 patients -35.3%-), Group B: from January 1998 to December 2007 (88 patients -34.9%-), and Group C: from January 2008 to December 2018 (75 patients -29.8%). The characteristics were analyzed and compared: age, sex, underlying heart disease, blood cultures and germs, presence of vegetations, surgical treatment and in-hospital mortality. Over the three decades, the predisposing heart condition showed that rheumatic valve disease decreased significantly (p < 0.0001) while the IE in cardiac devices also increased significantly (p < 0.0001). The percentage of blood culture-negatives decreased significantly over the years (p < 0.0001). In-hospital mortality showed a downward trend in the last decade (p = 0.069). The development of complications during hospitalization, the indication for surgery, and the presence of heart failure on admission were independent predictors of in-hospital mortality. The presence of vegetations and febrile syndrome on admission were independent predictor for lower mortality. The comparison over the years showed important changes in the epidemiological profile of IE. Probably due to advances in diagnostic techniques, treatment, and the implementation of interdisciplinary IE teams in the last decade, in-hospital mortality shows a strong tendency to decrease.

Se analizaron y compararon las características: edad, sexo, cardiopatía de base, hemocultivos y gérmenes, presencia de vegetaciones, tratamiento quirúrgico y mortalidad intrahospitalaria. Durante las tres décadas, la cardiopatía predisponente mostró que la enfermedad valvular reumática disminuyó significativamente (p < 0.0001) mientras que la EI en los dispositivos cardíacos aumentó significativamente (p < 0.0001). El porcentaje de hemocultivos negativos disminuyó significativamente a lo largo de los años (p < 0.0001). La mortalidad hospitalaria mostró una reducción en la última década (p = 0.069). El desarrollo de complicaciones durante la hospitalización, la indicación de cirugía y la presencia de insuficiencia cardíaca al ingreso fueron predictores independientes de mortalidad hospitalaria. La presencia de vegetaciones y síndrome febril al ingreso fueron predictores independientes de menor mortalidad. La comparación a través de los años mostró cambios importantes en el perfil epidemiológico de la EI. Probablemente por el avance en las técnicas diagnósticas, el tratamiento y la implementación de equipos interdisciplinarios de EI de la última década, la mortalidad intrahospitalaria marca una fuerte tendencia a la reducción.

Hypothyroid cardiomyopathy: A reversible phenocopy of hypertrophic cardiomyopathy.

We present the case of a 46-year-old patient with hypothyroidism secondary to Hashimoto's thyroiditis who was admitted with decompensation in the form of myxedema. A 2-D echocardiogram shows a septal asymmetric hypertrophy, with low-voltage QRS complex in the ECG and a bull's-eye map of longitudinal strain with preserved apical strain with reduction of mid and basal strain that results in "cherry on the top" pattern, similar to the most frequent phenocopy of hypertrophic cardiomyopathy, as is the cardiac amyloidosis, and that, unlike this pathology, reverted after the patient reached the euthyroid state.

[Cardiac metastasis from primary anaplastic thyroid carcinoma]. / Metástasis cardíaca de carcinoma anaplásico de tiroides.

Cardiac neoplasms are rare entities in the clinical practice. Cardiac metastatic involvement is 20 to 40 times more frequent than the primary form, representing 95% of all cardiac tumors; however, they are frequently underdiagnosed because of their clinical and oncologic features. In this report, we present two cases of cardiac metastasis from primary anaplastic thyroid carcinoma: a 69-years-old woman with right ventricular metastasis and a 61-years-old man with right atrial metastasis. Both patients died during their hospitalization and one of them underwent an autopsy.

Las neoplasias cardíacas son entidades poco frecuentes en la práctica clínica cardiológica y dentro de éstas, la afectación metastásica es 20 a 40 veces más frecuente que la forma primaria, correspondiendo al 95% de todos los tumores cardíacos; no obstante, debido a las características clínicas y oncológicas del tumor primario, los tumores cardíacos metastásicos son habitualmente subdiagnosticados. En este trabajo se presentan dos casos de pacientes con carcinoma anaplásico de tiroides, una mujer de 69 años con metástasis en ventrículo derecho y un varón de 61 años con metástasis en aurícula derecha. Ambos pacientes fallecieron durante la internación y a uno de ellos se le realizó autopsia.

Rapidly progressive aortic stenosis treated with transcatheter aortic valve implantation in a patient with Fabry disease: a case report.

BACKGROUND: Fabry disease (FD) is a rare lysosomal storage disease, caused by mutations in the gene encoding the enzyme α-galactosidase A (α-Gal A). Cardiac involvement is one of the main causes of death and it is characterized by progressive concentric left ventricular hypertrophy (LVH), which in most cases is symmetric. Mild thickening of the left-sided valves is seen in as many as a quarter of patients. Severe aortic stenosis is an extremely rare disorder in FD. CASE SUMMARY: In this report, we describe the case of a 57-year-old male, who was diagnosed with a cardiac variant of FD 10 years ago. Since the patient had severe LVH, he was started on enzyme replacement therapy when he was 47 years old with an intravenous infusion of 0.2 mg/kg of agalsidase alpha every 14 days. The patient remained stable and asymptomatic for 9 years, until he presented with dyspnoea in New York Heart Association functional class II-III and severe aortic stenosis (aortic valve area: 0.97 cm2) together with severe systolic dysfunction [ejection fraction (EF): 29%]. Because of the patient's comorbidities and high surgical risk, he underwent successful transfemoral transcatheter aortic valve implantation (TAVI). At 2 months following TAVI, the patient was asymptomatic and, in spite of his Fabry cardiomyopathy, the EF had increased to 45%. DISCUSSION: To our knowledge, this is the first case in the literature to demonstrate a rapid progression of aortic stenosis with severe impairment of left ventricular function and worsening in functional class in a patient with FD, who following TAVI improved his EF, with disappearance of symptoms and ventricular arrhythmias.

Clinical significance of tissue Doppler imaging in chronic Chagas disease.

INTRODUCTION: Chagas disease (ChD) is one of the main parasitic diseases in Latin-America. Its heart involvement is the most important cause of death. The aim of this study is to evaluate if Doppler Tissue Imaging (DTI) may have a predictive value for later events in subjects with chronic ChD. METHODS: we analyses DTI variables of 543 patients with chronic ChD for the evaluation of predicting factors of events. Major adverse cardiovascular events (MACE) were considered as stroke, heart failure resistant to treatment, sustained ventricular tachycardia, implantable cardioverter-defibrillator, sudden death, and cardiovascular death. The following findings were also included in total evens: heart failure, bradycardia, ventricular arrhythmia, new conduction system abnormalities, and new echocardiographic abnormalities. Multivariate analysis with logistic regression was used in order to assess the Doppler and DTI parameters predicting events. Variables with a P-value ≤ .5 in the univariate analysis were included in the multivariate analysis. RESULTS: In patients with chronic ChD, the analysis of DTI parameters showed that S' wave and E' wave of the lateral wall of the left ventricle were significant predictors of MACE (OR: 0.83; 95% CI: 0.71-0.96; P-value: .015 and OR: 0.80; 95% CI: 0.66-0.98; P-value: .031, respectively). CONCLUSIONS: This study found that patients with chronic ChD who had events showed significantly lower parameters in the DTI. What is more, this study showed that even lower DTI parameters are significant predictors of events.

Mechanical dispersion in Fabry disease assessed with speckle tracking echocardiography.

BACKGROUND: Fabry disease (FD) is a rare X-linked storage disorder caused by deficiency of the lysosomal enzyme α-galactosidase A, and it typically causes multiorgan dysfunction. The main cause of death is heart disease resulting from left ventricular (LV) diastolic dysfunction, LV systolic dysfunction, severe LV hypertrophy (LVH), and sudden death. In several cardiac disorders, LV systolic dysfunction and ventricular arrhythmias are associated with mechanical dispersion (MD). MD has until now not been studied in patients with FD. OBJECTIVE: To investigate the prevalence of MD in patients with FD. METHODS: Complete echocardiographic data and speckle tracking echocardiographic data were collected. MD is an index of inter-segmental discoordination of contraction and is defined as the standard deviation (SD) of the time-to-peak longitudinal negative strain in 17 LV segments with a value >49 milliseconds. Patients with FD were divided into the following 2 groups: group I (patients with FD but no LVH, n = 64) and group II (patients with FD and LVH, n = 25). These groups were compared with a group of healthy subjects (group III, n = 50). Parametric variables were expressed as mean ± SD, and nonparametric variables were expressed as median and inter-quartile range. A P value <.05 was considered significant. RESULTS: A total of 113 patients with FD were included in this study. Of these, 24 (21%) were excluded because of poor imaging quality or presence of comorbidities, and the final study population consisted of 89 patients (mean age of 33.5 ± 14.5 years, 64% female). Group II patients were older than group I patients (46 ± 13 years vs 27 ± 11 years, P < .0001). There was no difference in LV ejection fraction between the 3 groups. There was also no difference in MD between groups I and III (32.4 ms [26-39] vs 32 ms [26-39]). In group II, the MD in 19 patients (76%) was 56 ms (39-80). CONCLUSIONS: To the best of our knowledge, this is the first study to assess the prevalence of MD in patients with FD. MD was observed in 76% of patients with FD and LVH. The use of MD in strain echocardiography may be beneficial in the assessment of patients with FD who develop heart failure.

[Clinical examination and the Valsalva maneuver in heart failure]. / Examen clínico y maniobra de Valsalva en la insuficiencia cardíaca.

Congestion in heart failure patients with reduced ejection fraction (HFrEF) is relevant and closely linked to the clinical course. Bedside blood pressure measurement during the Valsalva maneuver (Val) added to clinical examination may improve the assessment of congestion when compared to NT-proBNP levels and left atrial pressure (LAP) estimation by Doppler echocardiography, as surrogate markers of congestion in HFrEF. A clinical examination, LAP and blood tests were performed in 69 HFrEF ambulatory patients with left ventricular ejection fraction ≤ 40% and sinus rhythm. Framingham Heart Failure Score (HFS) was used to evaluate clinical congestion; Val was classified as normal or abnormal, NT-proBNP was classified as low (< 1000 pg/ml) or high (≥ 1000 pg/ml) and the ratio between Doppler early mitral inflow and tissue diastolic velocity was used to estimate LAP and was classified as low (E/e'< 15) or high (E/e' ≥ 15). A total of 69 patients with HFrEF were included; 27 had a HFS ≥ 2 and 13 of them had high NT-proBNP. HFS ≥ 2 had a 62% sensitivity, 70% specificity and a positive likelihood ratio of 2.08 (p=0.01) to detect congestion. When Val was added to clinical examination, the presence of a HFS ≥ 2 and abnormal Val showed a 100% sensitivity, 64% specificity and a positive likelihood ratio of 2.8 (p = 0.0004). Compared with LAP, the presence of HFS = 2 and abnormal Val had 86% sensitivity, 54% specificity and a positive likelihood ratio of 1.86 (p = 0.03). In conclusion, an integrated clinical examination with the addition Valsalva maneuver may improve the assessment of congestion in patients with HFrEF.

Examen clínico y maniobra de valsalva en la insuficiencia cardíaca / Clinical examination and the Valsalva maneuver in heart failure

La evaluación de la congestión en pacientes con insuficiencia cardíaca y fracción de eyección reducida (ICFEr) resulta relevante y estrechamente vinculada al curso clínico. El agregado del comportamiento de la presión arterial durante la maniobra de Valsalva en la cabecera del paciente (VAL) podría mejorar la evaluación clínica de congestión cuando la comparamos con los niveles de NT-proBNP y la estimación de la presión media en la aurícula izquierda por Doppler cardíaco, como subrogantes de congestión. Se realizó un examen clínico con el VAL, un examen de laboratorio y un Doppler cardíaco en 69 pacientes ambulatorios con insuficiencia cardíaca y fracción de eyección ≤ 40% en ritmo sinusal. El score de Framingham ≥ 2 (SFr ≥ 2) se empleó para evaluar congestión clínica. VAL fue clasificado como normal o anormal, el NT-proBNP como bajo (< 1000 pg/ml) o alto (≥ 1000 pg/ml) y la relación entre la velocidad del llenado ventricular rápido y la velocidad del Doppler tisular (E/e') como baja < 15 o alta ≥ 15. Se halló que 13/27 pacientes con SFr ≥ 2 tenían NT-proBNP alto (sensibilidad 62%, especificidad 70% y razón de verosimilitud positiva [LR+] de 2.08, p = 0.01). El agregado del VAL al SFr ≥ 2 mejoró la exactitud diagnóstica (sensibilidad 100%, especificidad 64% y LR+ 2.8 p = 0.0004). Comparado con la E/e', SFr ≥ 2 con VAL anormal mostró sensibilidad 86%, especificidad 56% y LR + 1.86 (p = 0.03). En conclusión, el agregado del comportamiento de la presión durante la maniobra de Valsalva podría mejorar la evaluación clínica de la congestión en la insuficiencia cardíaca.

Bone cement cardiac and pulmonary embolism.

This case describes a complication of bone cement use. A 65-year-old male patient with back spine trauma caused by a fall, underwent a percutaneous vertebroplasty. Five years later, he consulted for palpitations, and the electrocardiogram showed supraventricular arrhythmia. A transthoracic two-dimensional echocardiography showed a hyperechogenic linear structure of 7 cm length, running from the lateral wall of the right ventricle to the right atrium through the tricuspid valve. This foreign body, which was suspicious for bone cement embolism, appeared rigid and was attached at the lateral wall of the right ventricle, with its proximal end free in the right atrium. The tip of the cement embolus was inside the myocardium of the lateral wall of the right ventricle, with risk of cardiac perforation. A fluoroscopy was performed, which confirmed the presence of cement within the right heart, with great mobility in each cardiac cycle. Chest computed tomography (CT) and multidetector CT three-dimensional reconstruction confirmed the presence of cement within the right heart. Chest CT showed two pulmonary embolisms, one in the right upper lobe and one in the left lower pulmonary lobe. This case emphasizes the risk of late clinical manifestations of cardiac and pulmonary embolism of methylmethacrylate after percutaneous vertebroplasty, suggesting that the risk of such embolism might be underestimated. We propose routine chest radiography, two-dimensional echocardiography, and chest CT after every percutaneous vertebroplasty, to detect asymptomatic cardiac and pulmonary embolism and thereby prevent serious delayed cardiopulmonary failures.

Pulmonary Edema Assessed by Ultrasound: Impact in Cardiology and Intensive Care Practice.

Pulmonary edema is a frequent condition found in adult patients hospitalized in cardiology wards and intensive care units. Ultrasonography is a diagnostic modality with a high sensitivity for the detection of extravascular lung water, visualized as B lines, and usually caused by cardiogenic or noncardiogenic pulmonary edema. This paper highlights a simple method for the assessment of patients with pulmonary edema, which allows for a differential diagnosis of its possible mechanism and contributes to therapeutic intervention guiding and monitoring.

Apical left ventricular hypertrophy and mid-ventricular obstruction in fabry disease.

We report the case of a rare cardiac presentation of Fabry disease. Although concentric left ventricular hypertrophy is a major cardiac finding in Fabry disease, there is no case report of dynamic obstruction at mid-left ventricular level. We describe a 59-year-old-woman suffering from a severe form of Fabry disease, mimicking an apical hypertrophic cardiomyopathy with mid-ventricular obstruction. Differentiation of Fabry disease from hypertrophic cardiomyopathy is crucial given the therapeutic and prognostic differences. Fabry disease should always be suspected in an adult, independently of the pattern of left ventricular hypertrophy.
