RESUMO

Isolation of the pulmonary veins by applying radiofrequency is an effective treatment for atrial fibrillation. One of the potential complications with higher clinical compromise utilizing this invasive technique is the occurrence of stenosis of one or more pulmonary veins. This complication can be treated by angioplasty with or without stent implantation, with an adequate clinical improvement, but with a high rate of restenosis.

RESUMO

Total anomalous pulmonary venous drainage is a rare and diverse anomaly, accounting for 1% to 3% of patients with congenital heart disease. Newborns with diagnosis of an obstructed total anomalous pulmonary venous dainage are extremely ill soon after birth and often present with severe cyanosis, pulmonary hypertension and low cardiac output requiring urgent surgical intervention. Transcatheter palliative stenting of the obstructive vertical vein can be an acceptable alternative as a bailout intervention before complete surgical correction is undertaken. This report of two cases highlights the feasibility, safety and effectiveness of the interventional palliative procedure and confirms that this technique can be an acceptable and attractive bridge in the algorithm of medical decisions during the evaluation of these critical patients.


El drenaje venoso pulmonar anómalo total es una enfermedad poco frecuente y de presentación diversa y se observa en el 1% a 3% de las cardiopatías congénitas. Si se asocia a obstrucción, se convierte en una afección grave en el recién nacido, mostrando cianosis intensa, hipertensión arterial pulmonar y bajo gasto cardíaco con indicación de intervención quirúrgica de urgencia. El implante de stent por cateterismo de forma paliativa para aliviar la obstrucción puede ser una alternativa aceptable de tratamiento como intervención de rescate antes de la corrección quirúrgica definitiva. Presentamos dos casos de intervención percutánea paliativa mostrando que esta técnica puede ser eficaz como puente al tratamiento quirúrgico definitivo para ser incorporado en la toma de decisiones de estos pacientes críticos.

RESUMO

BACKGROUND: We recommend the use of models to estimate mortality hospital risk in cardiac surgery (CC). The aim of this study was to validate a risk stratification system, widely used as the EuroSCORE (ES), in our institution. MATERIAL AND METHODS: We retrospectively analyzed the records of patients undergoing CC consecutively between January 2006 and November 2008. The ES was calculated retrospectively based on data from medical records. Mortality was considered until the time of discharge. In all patients, the ES was calculated by logistic and additive. To study the validity of the model, we analyzed their ability to calibration and discrimination through the goodness of fit test of Hosmer and Lemeshow and area under the ROC curve, respectively. RESULTS: 153 patients were included, mean age 64.1 ± 9.5 years, 77.8% men. The CRM was 60.8%, 24.8% and 14.4% valvular surgery combined (bypass + valve). Overall mortality was 3.9%. The area under the curve of the logistic model was 0.87 and the Hosmer Lemeshow test was 0.84. The area under the curve of the additive model was 0.86 and the Hosmer Lemeshow test was p = 0.89. A score greater than 7 points is additive had a sensitivity of 66% and 91,5% specificity for predicting hospital mortality. CONCLUSION: The ES is a useful model and can be used to estimate the risk of hospital mortality in CC in the city of Cordoba.

RESUMO

Introduction: High sensitivity cardiac Troponin T (hs-cTnT) dosage is recommended for myocardial infarction diagnosis, by applying the 99th percentile obtained from a healthy population by the manufacturer. The objective is to validate the 99th percentile in a population from our hospital (99L), compared with the manufacturer´s 99th percentile (99F) by using coronary angiography as gold standard. Materials and Methods: Retrospective analysis of every hs-cTnT (Roche) obtained from patients admitted with acute coronary syndromes (ACS) who underwent coronary angiography between 2015 and 2018. Results: 415 patients were included for analysis (118 females, 64.2 yo). 99F sensitivity (Sn) for significant coronary artery disease (stenosis >70%) was 83.6%, with a specificity (Sp) of 44.5%. Positive predictive value (PPV) and negative predictive value (NPV) were 77% and 55% respectively. 99L Sn was 69.7% and Sp 58.6%. PPV was 79% and NPV 46%. ROC curve was 0.641 for 99F and 0.641 for 99L. Conclusion: Given the importance of hs-cTnT in ACS diagnosis, the 99F should be the preferred upper reference limit since the sensitivity is better, although lower compared to prior studies.


Introducción: El dosaje de troponina ultrasensible (TnT US) se recomienda para el diagnóstico de infarto de miocardio, para lo cual se utiliza como punto de corte el percentil 99 (p99) obtenido por el fabricante (99F) en población sana. El objetivo de este estudio es validar el p99 obtenido en la población de este hospital (99L) frente al 99F, utilizando la cinecoronariografía (CCG) como gold standard. Materiales y Métodos: análisis retrospectivo de TnT US Roche realizada a todos los pacientes que ingresaron por SCA (síndrome coronario agudo) a los que se les realizó CCG entre 2015 y 2018. Se utilizó para el procesamiento estadístico el programa IBM SPSS Statistics 24 y tablas de sensibilidad y especificidad para métodos diagnósticos (EviCardio). Resultados: se incluyeron 415 pacientes, 118 de sexo femenino, con edad de 64,2 ± 12,5 años. La sensibilidad del 99F para diagnóstico de enfermedad coronaria severa (obstrucción ≥ 70%) fue de 83,6% y la especificidad, 44,5%. El valor predictivo positivo (VPP) fue de 77% y el negativo (VPN) 55%. La sensibilidad del 99L se calculó en 69,7% y la especificidad, 58,6%. El VPP fue 79% y el VPN 46%. El ABC (área bajo la curva) resultó ser 0,641 para el 99Fy 0,641 para el 99L Conclusiones: Debido a la importancia de la sensibilidad en el uso de la TnT US como herramienta diagnóstica ante la sospecha de SCA, debemos seguir utilizando el 99F ya que mostró mayor sensibilidad que 99L (aunque menor a la reportada en estudios previos).

RESUMO

OBJECTIVES: The aim of this study was to assess the additional utility of measuring left atrial (LA) pressure as a complement to transesophageal echocardiography (TEE) and Doppler imaging. BACKGROUND: The efficacy of the MitraClip (MC) is assessed intraoperatively by TEE. However, TEE measures are operator dependent and can be influenced by left ventricular (LV) function and changes in LA compliance. METHODS: Fifty patients undergoing MC therapy with continuous left-sided heart pressure measurements were analyzed. LA V-wave pressure (LAvP), LA mean pressure (LAmP), LV systolic pressure, and LV end-diastolic pressure were measured continuously. LA pressures were indexed to LV pressures to account for changes in afterload during the procedure. RESULTS: Most patients (70%) had degenerative mitral regurgitation (MR). TEE MR grade decreased from 3+ to 0+. LAvP (p < 0.001), LAmP (p = 0.007), LV end-diastolic pressure (p = 0.001), LAvP index (p < 0.001), and LAmP index (p = 0.001) decreased significantly, and LV systolic pressure(p = 0.009) significantly increased after MC therapy. In multivariate Cox regression analysis, intraprocedural increase of LAmP index, but not post-MC ≥2+ residual MR, was significantly associated with rehospitalization due to heart failure (hazard ratio: 3.377; 95% CI: 3.180 to 3.585; p = 0.007) and with New York Heart Association functional class III to IV (hazard ratio: 1.497; 95% CI: 1.006 to 2.102; p = 0.005) in the follow-up period. CONCLUSIONS: This study demonstrates the value of real-time monitoring of LA pressure during MC therapy to predict clinical outcomes. An increase in LAmP was a predictive of worse clinical outcomes at short-term follow-up, independent from echocardiographic findings.

RESUMO

BACKGROUND: Chronic kidney disease (CKD) has a negative impact on outcomes after transcatheter aortic valve replacement (TAVR). Data on outcomes in renal transplant recipients (RTRs) undergoing TAVR are scarce. We compared the outcomes in RTRs undergoing TAVR with matched patients who have native kidneys and similar kidney function. METHODS: This retrospective cohort study used data from 16 TAVR centres (13,941 patients). The study cohort included 216 patients (72 RTRs and 144 matched controls). RESULTS: The mean estimated glomerular filtration rate (eGFR) was 39.2 ± 23.6 vs 44.5 ± 23.6 mL/min for RTRs and control patients (P = 0.149), with a similar CKD stage distribution. After TAVR, the eGFR declined among RTRs but remained stable for up to 1 year in controls (P = 0.021). Long-term hemodialysis was required in 19 (26.4%) RTRs and 20 (13.8%) controls (hazard ratio [HR] = 2.09 95% confidence interval [CI], 1.03-3.86; P = 0.039) and was most often initiated during the periprocedural period (14 RTRs vs 16 controls; P = 0.039). After a median follow-up of 2.3 years, risk of death (29.2% vs 31.9%) and death/hemodialysis (40.3% vs 36.8%) was similar between the groups. The contrast volume/eGFR ratio was the strongest predictor of hemodialysis initiation (odds ratio [OR] = 1.64; 95% CI, 1.36-1.97 per 1 unit increase; P < 0.001), with a greater effect among RTRs than controls (P for interaction = 0.022). CONCLUSION: s: TAVR appears safe in RTRs with mortality rates similar to matched patients with native kidneys. However, RTRs carry an increased risk of progressive renal impairment and need for hemodialysis initiation after TAVR. Our data highlight the importance of minimizing contrast load during TAVR, particularly in RTRs.

RESUMO

We report the case of an 11-year-old girl with heterotaxy syndrome, dextrocardia, and azygos continuation of an interrupted inferior vena cava who had developed pulmonary arteriovenous fistulas after a Kawashima procedure consisting of bilateral superior cavopulmonary anastomoses. She presented with profound cyanosis, fatigue, and failure to thrive. An operative procedure to direct hepatic vein effluent to the pulmonary circulation was performed with placement of an extracardiac conduit between the hepatic veins and the left pulmonary artery. Persistence of cyanosis led to investigation, which led to the discovery of an unintentionally excluded right hepatic vein. A percutaneous transhepatic catheter intervention was performed in which a vascular plug was implanted to occlude the "missed" right hepatic vein, redirecting the flow through intrahepatic venovenous channels to the conduit. Clinical condition and arterial oxygen saturation were substantially improved one year after the two-step hepatic vein inclusion procedure.

RESUMO

INTRODUCTION: Are the current data on the Cardioband in the clinical area enough to consider it a tool for mitral regurgitation treatment? Severe secondary mitral valve insufficiency frequently affects high-risk surgical patients. The Cardioband system is a novel percutaneous surgical-like device for direct annuloplasty. It is implanted into the beating heart by transvenous femoral access, with minimal impact on hemodynamic and cardiac function during implantation. So far, it has demonstrated safety and feasibility in high-risk patients with functional mitral regurgitation; it has imparted significant annular reduction and regurgitation improvements. In well-selected patients, it could be an option for mitral valve repair. AREAS COVERED: This is a bibliographic review based on scientific publications and medical congress reports. It includes the most current information related to Cardioband in mitral regurgitation. EXPERT COMMENTARY: This novel, less-invasive and effective tool is an option for the open repair or replacement of the mitral valve in high-risk surgical patients. Although the current results of Cardioband are promising, more data and longer follow-up times are necessary to confirm its safety and efficacy and to evaluate the durability of the results.

RESUMO

RESUMEN Introducción: El manejo inicial de pacientes con tetralogía de Fallot (TOF) asociado a una anatomía desfavorable y flujo vascular pulmonar significativamente reducido es controversial y continúa siendo un desafío clínico. Material y métodos: Estudio multicéntrico, retrospectivo, observacional. Se incluyeron pacientes consecutivos (neonatos y lactantes menores) con diagnóstico de TOF asistidos en cuatro centros diferentes de la ciudad de Córdoba, Argentina, que recibieron stent en tracto de salida de ventrículo derecho (TSVD) como abordaje inicial de su cardiopatía congénita. La indicación de intervención paliativa inicial fue consensuada en reunión del equipo cardiovascular en cada centro participante. Una anatomía compleja (ramas pulmonares con Z score ≤ -2,5), presentación en shock cardiogénico o en crisis de cianosis, bajo peso o comorbilidades significativas (enterocolitis necrotizante, prematurez, insuficiencia renal, convulsiones) inclinaron la decisión hacia un abordaje percutáneo inicial. Resultados: Entre agosto de 2017 hasta mayo de 2018, 6 pacientes con TOF sintomáticos recibieron stent en TSVD. La edad media fue 39,3 días (9-87), el peso medio fue 3,60 kg (2,2-5,4) y el 66% eran de sexo femenino. Los stents utilizados fueron coronarios o periféricos con un diámetro que varió entre 4,0 y 6,0 mm. La saturación periférica previa a la colocación del stent fue de 66,4% (42-77) incrementado a 90,6% (86-96) previo al alta (p < 0,001). No se registraron complicaciones durante la intervención. El tiempo de internación fue de 7 días (1-13) y el tiempo de seguimiento fue de 106,8 días (4-292). No hubo mortalidad a los 30 días. Conclusión: El implante de stent en TSVD en pacientes con TOF y anatomía desfavorable es una opción razonable en neonatos y lactantes menores como alternativa a la realización de una anastomosis de Blalock-Taussig modificada o corrección primaria inicial.


ABSTRACT Background: The initial management of patients with Tetralogy of Fallot (TOF) associated with unfavorable anatomy and significantly reduced pulmonary blood flow is controversial and still a clinical challenge. Methods: We conducted a multicenter, retrospective and observational study in consecutive neonates and young infants with diagnosis of TOF treated at four different centers of the city of Cordoba, Argentina, who underwent RVOT stenting as the first approach to alleviate their congenital heart defect. The indication of a primary palliative intervention was decided by the cardiovascular surgery team in each participating center. An initial percutaneous approach was considered under the following circumstances: complex anatomy (pulmonary branches with Z score ≤-2.5), cardiogenic shock, cyanotic spells, low weight or significant comorbidities (necrotizing enterocolitis, prematurity, kidney dysfunction or convulsions). Results: From August 2017 to May 2018, 6 patients with symptomatic TOF underwent RVOT stenting. Mean age was 39.3 days (9-87), mean weight was 3.60 kg (2.2-5.4) and 66% were girls. Coronary or peripheral stents were used with diameter between 4.0 mm and 6.0 mm. Systemic arterial oxygen saturation was 66.4% (42-77) before the procedure and increased to 90.6% (86-96) before discharge (p<0.001) There were no complications during the procedure. Patients were hospitalized for an average of 7 days (1-13) and mean follow-up was 106.8 days (4-292). There were no deaths at 30 days. Conclusions: Right ventricular outflow tract stenting in patients with TOF and unfavorable anatomy is a reasonable option for neonates and young infants as an alternative to the modified Blalock-Taussig shunt or initial primary corrective surgery.

RESUMO

Introducción: El foramen oval permeable se encuentra en alrededor del 50% de los pacientes que han sufrido un accidente cerebrovascular criptogénico. La recurrencia de un accidente cerebrovascular isquémico luego del cierre percutáneo del foramen oval permeable es de alrededor del 1% anual. Objetivo: Evaluar la prevalencia de recurrencia de accidente cerebrovascular isquémico en nuestra población tratada con cierre percutáneo del foramen oval permeable. Material y métodos: Se incluyeron en forma retrospectiva desde enero de 2007 hasta septiembre de 2015 todos los pacientes con diagnóstico de accidente cerebrovascular isquémico criptogénico a quienes mediante técnica percutánea se les ocluyó un foramen oval permeable. En el seguimiento se detectaron los casos en los que se diagnosticó recurrencia de evento en la forma de un nuevo accidente cerebrovascular isquémico y/o ataque isquémico transitorio posterior al cierre percutáneo. Resultados: Se incluyeron 28 pacientes, con edad promedio al momento del procedimiento de 47 años (20-71 años), el 50% eran mujeres, el 79% habían tenido un accidente cerebrovascular y el 21% un ataque isquémico transitorio. El puntaje de RoPE fue de 7,07 puntos (3-10 puntos). El cierre percutáneo fue exitoso en todos los casos. En un período de seguimiento (mediana 989 días, intervalo intercuartil 670-1.766 días) se identificaron dos pacientes (7%) que tuvieron un nuevo accidente cerebrovascular. En ambos pacientes se repitió un ecocardiograma transesofágico y se encontró foramen oval permeable cerrado sin fugas residuales. Conclusiones: La frecuencia de recurrencia de accidente cerebrovascular es baja luego del cierre percutáneo del foramen oval permeable y posiblemente un buen número de los casos recurrentes no sean prevenibles con su cierre.

RESUMO

Introducción: La angioplastia con implante de stent se considera el tratamiento de elección para la mayoría de los casos de estenosis congénita o adquirida posquirúrgica de ramas de arterias pulmonares en pacientes portadores de cardiopatías con-génitas. Sin embargo, aún persisten dudas sobre la efectividad clínica y la incidencia de complicaciones de esta técnica que necesitan ser esclarecidas. Material y métodos: Estudio multicéntrico descriptivo, retrospectivo, observacional. Los procedimientos se realizaron desde enero de 2005 hasta abril de 2015. Un total 25 pacientes fueron sometidos a angioplastia con implante de stent en ramas de arterias pulmonares, los cuales fueron seguidos evolutivamente en su estado clínico y por diferentes métodos de imágenes. Se definió buena efectividad clínica al mejoramiento clínico sintomático y/o anatómico persistente del paciente intervenido. Resultados: La cohorte de 25 pacientes tenía una edad promedio de 9,48 años (2 meses-34 años), un peso promedio de 27,54 kg (3-104) y el 44% era de sexo femenino. Las cardiopatías congénitas de base intervenidas fueron en su mayoría tetralogía de Fallot y sus variantes, seguida por corazones con fisiología univentricular poscirugías de Glenn bidireccional y/o de Fontan-Kreutzer. La presión sistólica del ventrículo derecho y de la arteria pulmonar disminuyeron significativamente posintervención (de 68,35 mm Hg a 45,8 mm Hg y de 47,4 mm Hg a 32,08 mm Hg, respectivamente) (p < 0,0001). El diámetro mínimo de la lesión a tratar se incrementó significativamente posprocedimiento (de 3,98 mm a 9,82 mm; p < 0,0001). La incidencia de complicaciones fue del 8% (2 pacientes) y se registró buena efectividad clínica en 22 pacientes (88%). Conclusiones: La angioplastia con colocación de stent en las ramas de arterias pulmonares resultó una técnica segura y eficaz, aunque desafiante, con una marcada mejoría clínica y anatómica de las lesiones tratadas. Representa una alternativa a la cirugía, con disminución del riesgo de reintervenciones en pacientes con cardiopatías congénitas.

RESUMO

El aislamiento de las venas pulmonares mediante la aplicación de radiofrecuencia es un tratamiento efectivo de la fibrilación auricular. Una de las complicaciones potenciales y de mayor compromiso clínico de esta técnica invasiva es la estenosis de una o varias venas pulmonares. Esta complicación puede ser tratada mediante angioplastia con o sin colocación de stent, logrando una adecuada mejoría clínica, aunque con un alto índice de recurrencia por re-estenosis.


Isolation of the pulmonary veins by applying radiofrequency is an effective treatment for atrial fibrillation. One of the potential complications with higher clinical compromise utilizing this invasive technique is the occurrence of stenosis of one or more pulmonary veins. This complication can be treated by angioplasty with or without stent implantation, with an adequate clinical improvement, but with a high rate of restenosis.
