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.

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.

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.

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.

Abstract INTRODUCTION: Chagas disease is one of the most common diseases in Latin America and heart involvement is the main cause of death. This study aimed to determine differences in tissue Doppler imaging (TDI) parameters in the assessment left and right ventricular function in patients with the indeterminate form of Chagas disease compared to those in healthy controls. METHODS: We compared 194 patients with the indeterminate form of Chagas disease to 72 age-matched healthy individuals. We considered p-values <0.05 to be statistically significant. RESULTS: TDI analysis of the right ventricular (RV) showed lengthened isovolumic relaxation time (IRT) and higher RV index of myocardial performance (RIMP) and left ventricle (LV) index of myocardial performance (LIMP) in the Chagas group than in the control group, indicating RV and LV systolic and diastolic myocardial damage. TDI analysis of the myocardial velocities of the interventricular septum and the lateral wall of the LV also showed a systolic and diastolic myocardial damage. CONCLUSIONS: The study results demonstrated early LV systolic and diastolic myocardial damage in the RV and LV in patients with the indeterminate form of Chagas disease by TDI. These early findings of RV and LV dysfunction may help identify patients who will progress to heart failure during the disease course. TDI should be included in initial patient evaluations because it allows adequate follow-up and treatment.
