Outcome of moderate-severe tricuspid regurgitation after pulmonary endarterectomy or balloon pulmonary angioplasty.

INTRODUCTION AND OBJECTIVES: The management of persistent moderate-severe tricuspid regurgitation (TR) in patients with chronic thromboembolic pulmonary hypertension after treatment with pulmonary endarterectomy (PEA) or balloon pulmonary angioplasty (BPA) is not well defined. This study aimed to analyze the progression and predictors of significant persistent postintervention TR and its prognostic impact. METHODS: This single-center observational study included 72 patients undergoing PEA and 20 who completed a BPA program with a previous diagnosis of chronic thromboembolic pulmonary hypertension and moderate-to-severe TR. RESULTS: The postintervention prevalence of moderate-to-severe TR was 29%, with no difference between the PEA- or BPA-treated groups (30.6% vs 25% P=.78). Compared with patients with absent-mild postprocedure TR, those with persistent TR had higher mean pulmonary arterial pressure (40.2±1.9 vs 28.5±1.3mmHg P <.001), pulmonary vascular resistance (472 [347-710] vs 282 [196-408] dyn.s/cm5; P <.001), and right atrial area (23.0 [21-31] vs 16.0 [14.0-20.0] P <.001). The variables independently associated with persistent TR were pulmonary vascular resistance> 400 dyn.s/cm5 and postprocedure right atrial area> 22cm2. No preintervention predictors were identified. The variables associated with increased 3-year mortality were residual TR and mean pulmonary arterial pressure> 30mmHg. CONCLUSIONS: Residual moderate-to-severe TR following PEA-PBA was associated with persistently high afterload and unfavorable postintervention right chamber remodeling. Moderate-to-severe TR and residual pulmonary hypertension were associated with a worse 3-year prognosis.

Rehabilitación en pacientes con artroplastia total de cadera durante la pandemia del COVID-19. Resultados funcionales / Rehabilitation in patients with total hip arthroplasty during the Covid-19 pandemic. Functional outcomes

Introducción: La pandemia del COVID-19 revolucionó muchos aspectos de la vida de las personas y aquellos pacientes que necesitaban una rehabilitación luego de una artroplastia total de cadera (ATC) no fueron la excepción. Objetivo: Determinar si existe alguna diferencia en los resultados funcionales entre la rehabilitación supervisada y la autoadministrada después de una ATC. Materiales y métodos: Se recolectaron datos de 2 grupos de pacientes: los operados de ATC unilateral que realizaron rehabilitación supervisada y aquellos operados durante la pandemia, que recibieron rehabilitación sin supervisión, autoadministrada. Se compararon los resultados funcionales de ambos grupos a los 3 meses y al año de la cirugía mediante el Harris Hip Score modificado (HHSm) y el Forgotten Joint Score (FJS). Resultados: No se encontraron diferencias significativas en el HHS entre ambos grupos a los 3 ni a los 12 meses (p 0,18). Por el contrario, se observó una diferencia estadísticamente significativa (p <0,001) en el FJS, fue superior para la fisiokinesioterapia no supervisada, tanto a los 3 meses como al año. Ambos puntajes mejoraron a los 12 meses, en los dos grupos (p <0,001). Conclusiones:Tanto la rehabilitación supervisada como la no supervisada deben ser consideradas después de una ATC. Nuestros resultados han demostrado que la supervisión no implica una rehabilitación más pronta ni eficaz, esto otorga la posibilidad de una rehabilitación no supervisada para aquellos pacientes que así lo requieran. Nivel de Evidencia: IV

Introduction: The COVID-19 pandemic had a significant impact on many parts of people's lives, including those who needed rehabilitation after primary hip arthroplasty. Objective: To determine if there is a difference in functional outcomes between supervised and self-administered rehabilitation after THA. materials and methods: Data were collected from two groups of patients: those who were operated on for unilateral THA and received supervised rehabilitation, and those who were operated on during the pandemic and experienced unsupervised, self-directed rehabilitation. The functional outcomes of both groups were compared three months and one year following surgery using the modified Harris Hip Score (mHHS) and the Forgotten Joint Score (FJS). Results: No significant differences were found in HHS between the two groups at 3 and 12 months (p 0.18). On the contrary, a statistically significant difference (p <0.001) was observed in the FJS, which was superior for unsupervised THA, both at 3 months and at 1 year. After 12 months, both scores showed significant improvement in the two groups (p < 0.001). Conclusion: After a THA, both supervised and unsupervised rehabilitation options should be considered. Our findings indicate that supervision does not result in faster or more successful rehabilitation, therefore enabling unsupervised rehabilitation for patients who require it. Level of Evidence: IV

Scimitar syndrome: complete anatomical and functional diagnosis with gadolinium-enhanced and velocity-encoded cine MRI.

We report an asymptomatic 8-year-old girl with anomalous pulmonary venous connection to the IVC and systemic arterial supply (scimitar syndrome). We present for the first time a description of gadolinium-enhanced 3D MR angiography that provided concurrent non-invasive complete anatomical (arterial and venous supply) and 'functional' (calculation of left-to-right shunt using phase-contrast-MRI performed in the ascending aorta, main pulmonary artery and anomalous pulmonary vein) diagnosis, avoiding the need for more traditional invasive techniques. As the shunt quantification was less than 2:1, conservative management was decided upon.
