ABSTRACT

BACKGROUND/AIMS: We assessed the feasibility of renal sympathetic denervation (RDN) treatment in patients with resistant hypertension using the Iberis® RDN system. This study was a prospective, multicenter, single-arm feasibility registry. METHODS: We collected data from patients who underwent RDN treatment using the Iberis system. From November 2014 to February 2016, 16 patients from 6 centers in Europe were enrolled in this registry. RESULTS: Consistent reductions in the 24-h systolic blood pressure (SBP) and diastolic blood pressure were obtained. At any follow-up point, more than 70% of the patients were responders. The change in the 24-h SBP at 1 month was strongly correlated with that at 12 months. CONCLUSION: The Iberis system is safe and effective in patients for the treatment of resistant hypertension. Furthermore, our results suggest that we can estimate the effect of RDN in the long term at the 1-month follow-up point using the 24-h SBP.

ABSTRACT

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is an alternative therapy for high-risk patients with symptomatic aortic stenosis. TAVI without balloon aortic predilation (BPD) has been found to be as feasible and safe as the standard approach with predilation. The aim of this study was to show the usefulness of transesophageal echocardiographic (TEE) criteria during patient selection for TAVI without BPD and compare the results with those from a control group. METHODS: Two hundred forty-nine consecutive patients with severe symptomatic aortic stenosis underwent echocardiographic evaluation before TAVI. Two-dimensional and three-dimensional TEE imaging was used to evaluate the aortic annulus and root, leaflet mobility and degree of calcification, orifice characteristics, valve area, and aortic regurgitation. After TEE data were reviewed, patients were considered to be favorable candidates, or not, for TAVI without BPD on the basis of specific echocardiographic criteria. RESULTS: The mean age was 82 ± 5 years. Seventy-nine patients underwent TAVI without BPD, and 170 patients underwent TAVI with BPD. The mean aortic valve area was 0.61 ± 0.16 cm(2), and the mean aortic annular diameter was 2.2 ± 0.25 cm. In the group without BPD, Edwards SAPIEN XT valves were implanted in 64.6% (n = 51) and Medtronic CoreValve prostheses in 35.4% (n = 28). In this group, residual paravalvular aortic regurgitation immediately after valve deployment was seen in 53.2% of patients, without differences from those who underwent TAVI with BPD. Permanent pacemaker implantation was less frequent in the group of patients without BPD (6.3% vs 14.1%, P = .030). Procedure-related mortality was significantly lower in patients without BPD (2.5% vs 11.8%, P = .018). CONCLUSIONS: Thorough TEE assessment of aortic valve features permits the selection of patients with ideal conditions for TAVI without BPD, regardless of the type of prosthesis. Using the echocardiographic criteria described here, it is possible to achieve a good rate of procedural success with a low complication rate in patients undergoing TAVI without BPD.

ABSTRACT

The most common etiology of tricuspid stenosis is rheumatic, and in most cases it is associated with valvular regurgitation. Interestingly, there have been reports of tricuspid stenosis without associated valvular regurgitation, mostly related to pacemaker leads. Percutaneous tricuspid valvuloplasty may be a therapeutic alternative to surgery in cases of pure tricuspid stenosis without other concomitant valvulopathies. We report the case of a 52-year-old woman with pacemaker lead-related tricuspid stenosis successfully treated with percutaneous valvuloplasty guided by 3D echocardiography.

ABSTRACT

Tras el implante de prótesis percutánea aórtica CoreValve®, pueden aparecer trastornos de conducción auriculoventricular que precisan marcapasos permanente (un 40-45% de los pacientes). El objetivo de nuestro estudio es detectar si alguna variable ecocardiográfica de 2 o 3 dimensiones podría predecir la aparición de trastornos de conducción auriculoventricular. Para ello se estudió en 26 pacientes consecutivos la relación de la prótesis con el septo interventricular; 12 pacientes (46,1%) presentaron trastornos de conducción auriculoventricular tras el procedimiento. Una penetración protésica en el tracto de salida del ventrículo izquierdo > 12 mm y una superficie de contacto del stent de la prótesis con el septo interventricular en diástole > 90% se asociaron fuertemente con la aparición de trastornos de conducción auriculoventricular (87,5%; p=0,034). La superficie de contacto del stent resultó ser el único predictor independiente de dicha complicación (odds ratio=1,12; intervalo de confianza del 95%, 1,01-1,25; p=0,03). Los resultados indican que la implantación más alta de las prótesis y la reducción de la longitud del stent podrían reducir la frecuencia de esta complicación (AU)


Atrioventricular conduction disorders can appear after the implantation of percutaneous aortic CoreValve® prostheses in patients requiring permanent pacemakers (40%-45% of these patients). The aim of our study was to detect if 2- or 3-dimensional echocardiographic variables could predict the appearance of atrioventricular conduction disorders. For this purpose, the relationship of the prosthesis with the interventricular septum was studied in 26 consecutive patients. Twelve patients (46.1%) developed atrioventricular conduction disorders. A prosthetic penetration >12 mm in the left ventricular outflow tract and a contact surface >90% between the interventricular septum and the stent of the prosthesis in diastole were strongly associated with the appearance of conduction disturbances (87.5%; P=.034). The percentage of the prosthetic stent in contact with the interventricular septum in end diastole was the only independent predictor of atrioventricular conduction disorders (odds ratio=1.12; 95% confidence interval, 1.01-1.25; P=.03). The results suggest that a higher implantation of the prosthesis and a reduced stent length might decrease the incidence of this complication (AU)

ABSTRACT

Se revisan los avances más relevantes relacionados con el tratamiento de reperfusión en pacientes con infarto agudo de miocardio. En primer lugar, se revisa el papel que tuvo la fibrinolisis intravenosa, pero sobre todo se actualiza el papel de las terapias coadyuvantes antitrombóticas y antiplaquetarias, la evidencia del uso de stents convencionales frente a stents farmacoactivos en el infarto, de los dispositivos de aspiración trombótica y en especial el gran cambio que ha supuesto la introducción de la angioplastia coronaria percutánea primaria como estrategia más eficiente de reperfusión en el infarto agudo de miocardio; se resalta el papel de los modelos de organización en red de la asistencia a pacientes con infarto agudo de miocardio basados en realizar angioplastia primaria en el menor tiempo posible, sobre el principio de llevar al paciente desde el sitio del primer contacto con el sistema sanitario directamente al laboratorio de hemodinámica, para conseguir el menor tiempo de isquemia-reperfusión (AU)


This paper contains a review of the most significant developments in reperfusion therapy for patients with acute myocardial infarction. Firstly, the role of intravenous fibrinolysis is considered. However, the main focus is on recent developments in the use of adjuvant antithrombotic and antiplatelet therapy; comparisons of bare metal and drug-eluting stent use in infarctions; the role of thrombus aspiration devices; and, in particular, the significant progress brought about by the introduction of primary percutaneous coronary angioplasty, which is most effective reperfusion strategy for acute myocardial infarction. In addition, the article also highlights the role of organizational models for health-care networks for patients with acute myocardial infarction, which operate on the basis of carrying out primary angioplasty as quickly as possible. The guiding principle is that the patient should be transferred directly from the site of first contact with the health-care system to the catheterization laboratory in order to achieve the shortest ischemia-reperfusion time (AU)

ABSTRACT

La estenosis valvular aórtica severa degenerativa tiene mal pronóstico con tratamiento médico. Se ha demostrado que la cirugía de sustitución valvular es un tratamiento muy eficaz y seguro en los pacientes sometidos a él. Sin embargo, son muchos los pacientes que, por diferentes razones (edad, comorbilidades graves, riesgo quirúrgico excesivo, etc.), nunca llegan a ser operados. En estos pacientes se ha propuesto una terapia alternativa mediante la implantación transcatéter de prótesis valvular aórtica. Están disponibles dos modelos de prótesis transcatéter (Edwards y Medtronic CoreValve). El modelo Edwards se implanta por vía transfemoral y transapical; la Medtronic CoreValve ha tenido como vía de acceso la transfemoral con alguna experiencia por vía transapical. Con ambos modelos se han observado buenos resultados, progresivamente mejores, en registros individuales y multicéntricos. Los resultados pendientes del estudio aleatorizado PARTNER determinarán el verdadero papel de la prótesis transcatéter en diferentes contextos. Nuevos modelos (Direct Flow, Sadra Lotus, HLT) están en diferentes estadios de evaluación clínica, dispuestos a incrementar el arsenal de esta nueva tecnología que, sin duda, tendrá un impacto muy importante en el tratamiento de la estenosis valvular aórtica severa degenerativa (AU)


Patients with severe degenerative aortic stenosis who receive medical treatment have a poor prognosis. Surgical valve replacement has been shown to be very safe and effective in patients who receive such treatment. Nevertheless, a significant number do not undergo surgery for various reasons (e.g. age, serious comorbid conditions and excessive surgical risk). For this group, the alternative therapeutic approach of transcatheter aortic valve prosthesis implantation has been proposed. Two different types of transcatheter aortic valve prosthesis are available: the Edwards and Medtronic CoreValve prostheses. The Edwards aortic valve can be implanted using either transfemoral or transapical access, while transfemoral access is usually used with the Medtronic CoreValve, though some experience has been gained with transapical access. Both types of valve have demonstrated increasingly good clinical results in both single-center and multicenter studies. The findings of the randomized PARTNER study, which are still awaited, will be decisive in defining the true role of transcatheter valve implantation in various clinical settings. New types of valve (e.g. the Direct Flow, Sadra Lotus and HLT valves) are in different stages of clinical evaluation and are set to increase the armamentarium of this new technology, which will, without doubt, have a substantial impact on the treatment of severe degenerative aortic valve stenosis (AU)

ABSTRACT

Este informe refleja el interés de la Sección de Hemodinámica y Cardiología Intervencionista de la Sociedad Española de Cardiología en incrementar la calidad, seguridad y aplicabilidad del intervencionismo cardíaco, proporcionando claves científicas que contribuyan a optimizar las funciones de planificación o formación en este campo y que ayuden a reforzar la capacidad y el prestigio de los cardiólogos intervencionistas españoles. El documento ha sido redactado con el propósito de describir la verdadera dimensión de la cardiología intervencionista actual, identificar referencias de calidad y establecer los niveles mínimos aceptables para actuar o impartir enseñanza avanzada en esta disciplina. Para ello, se ha buscado un marcador sólido de calidad global dentro de las distintas técnicas percutáneas y se han analizado los resultados de las intervenciones, así como su relación con circunstancias de diversa índole. Dicho análisis ha identificado a la angioplastia coronaria como el patrón de referencia en el que deben basarse los requerimientos técnicos o cognitivos del intervencionismo cardíaco de cualquier tipo, los estándares de calidad y las recomendaciones sobre capacitación o formación. Por otra parte, se ha constatado la influencia crucial que ejercen la experiencia y el conocimiento sobre los resultados, especialmente en los escenarios anatomoclínicos más desfavorables o técnicamente más complejos. Sobre esta base, el informe establece recomendaciones concretas sobre requisitos de cualificación o formación. También aboga por la consideración de la cardiología intervencionista como una subespecialidad de la cardiología que debería requerir una acreditación específica (AU)
