La diálisis nueva post TAVI aumenta la mortalidad.

The need for dialysis after TAVR increases mortality

The need for dialysis after TAVR increases mortality

Courtesy of Dr. Carlos Fava. Stage III or higher renal impairment is frequent before TAVR, and the need for new dialysis after the procedure may reach up to 20%. Within that percentage, 5% may require permanent dialysis, which increases mortality up to 9 times at one year. In that sense, factors leading to that complication have not

Los marcapasos post TAVI aumentan los costos pero no los eventos adversos

Pacemaker Implantation After TAVI Raises Costs But Not the Incidence of Adverse Events

This new meta-analysis did not manage to prove whether permanent pacemaker implantation after transcatheter aortic valve replacement (TAVR) raises the rates of mortality, infarction, or stroke. Implantation could only be associated to a lesser recovery of ventricular function after the procedure, something that had already been observed in previous studies. Patients who required a pacemaker undoubtedly

La angioplastia “ad hoc” durante el TAVI no impacta en su seguridad ni en resultados a largo plazo

“Ad Hoc” PCI during TAVR: No Impact on Safety or Long Term Outcomes

According to a recent study published in Circulation Cardiovascular Interventions, screening for coronary artery disease (CAD) with an invasive coronary angiography  (as part of the protocol prior TAVR)  and performing PCI and TAVR in the same session, has no impact on periprocedural safety or on long term outcomes. Study outcomes offer new hope, especially as regards using TAVR

La válvula CoreValve Evolut R arroja resultados positivos en una población importante de pacientes La Evolut R, al igual que su predecesora CoreValve, es una válvula autoexpandible, supra-anular, de pericardio porcino en un stent de nitinol. Entre las mejoras de esta válvula se pueden enumerar su mejor perfil y la posibilidad de re-envainarla. Esto la hace completamente reposicionable e incluso recapturable. Faltaba ver si estas ventajas técnicas se traducirían en ventajas clínicas (lo cual es -en definitiva- lo que importa) en una población grande de pacientes del mundo real. El estudio FORWARD (CoreValve Evolut R FORWARD) es un registro prospectivo que incluyó 1038 pacientes de 53 centros y cuatro continentes. Los pacientes tuvieron una edad media de 81.8 ± 6.2 años y un STS de 5.5 ± 4.5%, lo cual constituye un riesgo intermedio y coincide con la tendencia actual de la práctica clínica. La capacidad de reposicionar la válvula debió ser utilizada en el 25.8% de los pacientes, característica que permitió el implante de una sola válvula en el lugar correcto en el 98.9% de los casos. A 30 días, la mortalidad fue del 1.9% y el stroke incapacitante del 1.8%. Solo el 1.9% de los pacientes presentó insuficiencia aórtica moderada a severa; la tasa de marcapaso definitivo fue del 17.5%. Ambos datos están por debajo de lo que mostró el estudio SURTAVI con la CoreValve en una población similar (3.4% y 25.9% respectivamente) y la mejora se puede atribuir a la posibilidad de reposicionar el dispositivo. Conclusión La nueva generación de la válvula autoexpandible es segura y efectiva en pacientes con estenosis aórtica severa no seleccionados del mundo real. Comentario editorial La mortalidad por cualquier causa del 1.9% está claramente por debajo del 5.5% esperado según el score de STS y en sintonía con la del 1.1% descripta en el registro que testeó la última generación de la válvula balón expandible SAPIEN 3 en una población similar. El 98% de los pacientes fueron tratados por acceso femoral, lo cual también es la tendencia mundial gracias a la significativa disminución del perfil de los dispositivos. Afortunadamente, la enorme mayoría de las mejoras técnicas que han incorporado los nuevos dispositivos (tanto este como la competencia) han logrado traducirse en mejoras clínicas para los pacientes, logrando reducir la insuficiencia paravalvular, la tasa de marcapaso y las complicaciones vasculares.

Positive Outcomes of CoreValve Evolut in Large Population

The Evolut R, as well as its predecessor the CoreValve, is a self-expandable valve, supra-annular, made of porcine pericardium in a nitinol frame. Amongst its improvements, it has a better profile and the option to resheath. This makes it fully repositionable and even recapturable.   We only needed to confirm these technical advantages would translate into clinical

Predicción de mortalidad en TAVI - Marcapaso

A Simple Electrocardiography to Predict Mortality in TAVR

Conduction abnormalities, such as new left bundle branch block, atrioventricular block, and need for a pacemaker, are still among the most frequent complications in transcatheter aortic valve replacement (TAVR). New valve generations have (mostly) not managed to reduce significantly electrical abnormalities; furthermore, some modifications such as external skirts, which are extremely effective for the reduction

Diálisis post TAVI, una complicación grave que se hace menos frecuente

Post TAVR Dialysis: a Severe Complication Less and Less Frequent

The prevalence of pre-procedural kidney failure in patients undergoing transcatheter aortic valve replacement (TAVR) can be as high as 50 – 60% (stage 3 kidney failure or worse); it has been strongly associated with acute kidney deterioration and, ultimately, an increase of post TAVR mortality. A recent meta-analyzis of several small studies carried out in a single

Sangrado y mortalidad en el reemplazo valvular aórtico por catéter

Bleeding and Mortality in Transcatheter Aortic Valve Replacement

Transcatheter aortic valve replacement (TAVR) is much less invasive than surgical replacement. This is associated with a substantial reduction in bleeding events (up to 60% less). However, clinically relevant bleeding is still present in one every four patients who undergo TAVR, which is associated with morbidity and mortality.   Cases of bleeding are not uniform: they may

¿Cómo objetivar la fragilidad en pacientes con estenosis aórtica?

How to standardize frailty in aortic stenosis patients

Frailty is the patient’s diminished capacity to recover after pathological or iatrogenic processes. It has a fundamental role when considering valve replacement, be it surgical (SAVR) or transcatheter (TAVR).   This was clearly observed in the PARTNER I and Core-Valve Pivotal trials, which showed that despite a 95% technical success, 2 in 5 patients showed poor quality

La revascularización incompleta se asocia a mortalidad en el TAVI

Incomplete Revascularization Is Associated with Mortality in TAVR

Courtesy of Dr. Carlos Fava. TAVR has proven to be beneficial for inoperable and high-risk patients, as well as for intermediate-risk patients. However, while many comorbidities have been analyzed, the presence, severity, and impact of coronary disease has not been well studied yet. This study analyzed 1270 patients who underwent TAVR. They presented >50% lesions in a major epicardial

El deterioro de las válvulas por catéter es raro y no debería impedir el avance a poblaciones más jóvenes

Valve Deterioration after TAVI Is Rare and Should Not Prevent Advancement to Younger Populations

Durability ─or better yet, lack of deterioration─ is still a matter of debate when considering transcatheter aortic valve intervention (TAVI), especially now that it is being explored as a real alternative for younger patients. A recently published meta-analysis offers more evidence and suggests TAVI deterioration is mostly rare within the first 5 years.   According to
