RESUMO

INTRODUCTION AND OBJECTIVES: Severe tricuspid regurgitation (TR) is associated with poor prognosis when left untreated, and a growing number of studies on transcatheter tricuspid valve repair (TTVr) have been published over the last few months. METHODS: We performed a comprehensive systematic review of published literature providing clinical data on TTVr for patients with significant TR. Early and mid-term clinical and echocardiographic outcomes were evaluated. Risk ratios (RR) or mean differences (MD) were obtained when comparing pre- and postprocedural data. A sensitivity analysis was also performed according to the main approach for repair (edge-to-edge vs annuloplasty). RESULTS: A total of 19 studies (all observational or single-arm trials) and 991 patients who underwent isolated TTVr were included. Thirty-day mortality and stroke rates were 2.8% and 0.2%, respectively. Pooled random-effects resulted in a significant reduction of ≥ severe TR (RR, 0.33; 95%CI, 0.26-0.42; P < .001), vena contracta width (MD, 5.9mm; 95%CI, 4-7.9; P <.001), right ventricular end-diastolic diameter (MD, 3.5mm; 95%CI, 2.5-4.5; P <.001), and New York Heart Association (NYHA) class III or IV at last follow-up (RR, 0.32; 95%CI, 0.27-0.37; P <.001). Bleeding complications and residual ≥ severe TR were numerically higher in the annuloplasty-like group compared with edge-to-edge repair (13.3% vs 3.8% for bleeding and 40.4% vs 27.9% for residual severe TR). CONCLUSIONS: Among 991 patients comprising the early experience for several TTVr devices, there was a statistically significant reduction in ≥ severe TR, NYHA class III-IV, vena contracta width and right ventricular end-diastolic diameter after TTVr. Thus far, the edge-to-edge approach seems to be associated with a better safety profile.

RESUMO

Abstract Objective: In recent years, transcatheter aortic valve replace (TAVR) has revolutionized the interventional treatment of aortic stenosis, however, only scarce evidence considers it as treatment for Aortic Regurgitation (AR). At present, the treatment of Pure AR of Native Valve with TAVR does not fall within the recommendations of international guidelines, as it poses multiple challenges with immediate and long-term variable and unpredictable results. The objective of this paper is to present the case of a patient with prohibitive operative risk that benefited of TAVR treatment for AR. Materials and methods: We present the case of a 79-year-old male patient who has severe Pure Native Aortic Valve Regurgitation, considered inoperable. Based on the heart team's decision, TAVR was planned with the use of an Edwards SAPIEN 3 valve. After TAVR, the patient developed complete heart block and a pacemaker was implanted. He improved to NYHA II functional class. At 15-month follow-up, he suffered intracranial hemorrhage and passed away. Results and Conclusions: Management of patients with severe symptomatic AR with high surgical risk continues to be a special challenge. They have high mortality if left untreated with valvular change, despite medical treatment. Even though it is strictly off-label, TAVR might be a reasonable solution for a select type of patients who are considered inoperable due to surgical high mortality risk.


Resumen Objetivo: En años recientes, el reemplazo valvular aórtico vía percutánea (TAVI) ha revolucionado el tratamiento de los pacientes con estenosis aórtica, sin embargo, poca evidencia la considera como opción de tratamiento en pacientes con insuficiencia aórtica (IA), especialmente en pacientes con Insuficiencia Aórtica Pura de Válvula Nativa (IAPVN), dado que esta patología confiere múltiples retos con resultados muy variables tanto a corto como a largo plazo. Dada su alta mortalidad en caso de permanecer sin tratamiento, la primera opción de tratamiento es la cirugía de cambio valvular. Material y Métodos: Presentamos el caso de un masculino de 79 años con IAPVN grave considerado inoperable dadas las comorbilidades. De acuerdo con la decisión del equipo de Cardiología, se decidió realizar TAVI con la colocación de una Válvula Edwards SAPIEN 3. El paciente desarrolló bloqueo AV completo como única complicación y se colocó marcapasos permanente. Permaneció en clase funcional NYHA II. A los 15 meses de seguimiento presentó hemorragia intracraneal y falleció. Resultados y Conclusiones: El manejo de los pacientes con IAPVN grave sintomática con riesgo quirúrgico alto sigue siendo un reto especial. Tienen alta mortalidad si no se realiza cambio valvular a pesar de tratamiento médico. A pesar de que no se recomienda en las guías actuales, la TAVI puede ser una opción razonable para un grupo muy selecto de pacientes que son considerados inoperables.

RESUMO

Resumen La endocarditis infecciosa es un proceso patológico de baja incidencia en la clínica diaria; su principal etiología son los agentes bacterianos, los cuales colonizan con mayor prevalencia de válvula mitral y aortica. En este artículo se presenta el estudio de un perro con diagnóstico previo de síndrome vestibular periférico secundario a probable otitis media-interna. Se presenta con un soplo de aparición súbita, claudicaciones intermitentes, inapetencia, depresión y fiebre, por lo cual se hace la valoración ecocardiográfica, donde se evidencia engrosamiento valvular mitral, acompañado de estructuras hiperecoicas en el borde libre que corresponden a lesiones vegetativas. Por medio de los criterios de Duke modificados se obtiene un diagnóstico definitivo de endocarditis infecciosa, para lo cual se realiza manejo médico intrahospitalario, sin evolución favorable. Los hallazgos clínicos y paraclínicos coinciden con lo reportado en la literatura. Los criterios de Duke modificados permiten orientar el diagnóstico y evidenciar signos clínicos de alarma. El manejo médico antimicrobiano deberá realizarse con base en hemocultivos y pruebas de sensibilidad, siempre teniendo en cuenta la prevalencia de patógenos y el origen primario de la infección. Se debe considerar como una patología con un pronóstico malo y un porcentaje de fatalidad alto. Finalmente, se concluye que la principal limitación del caso es la falta de confirmación histopatológica.


Abstract Infectious endocarditis is a pathological process with low incidence in the daily clinical practice. The main etiology are the bacterial agents that colonize with higher prevalence the mitral and aortic valves. This paper reports the case of a dog with a previous diagnosis of peripheral vestibular syndrome secondary to probable otitis media-interna. The dog has a sudden heart murmur, intermittent claudications, lack of appetite, depression and temperatures. It is performed an echocardiographic assessment that shows mitral valve thickening with hyperecoic structures in the free border that indicates vegetations. Using the Modified Duke Criteria, a definitive diagnosis of infectious endocarditis is concluded. The dog is provided a medical treatment at the clinic without success. The clinical and paraclinical findings match the background found in the literature. Modified Duke Criteria allow guiding the diagnosis process and uncovering the alarm clinical signs. Antimicrobial clinical treatment must be administered based on blood cultures and sensitivity tests and considering both the pathogen prevalence and infection primary origin. Doctors must deem this condition as a bad prognosis pathology with a high mortality percentage. Finally, it is concluded that the main limitation in this case is a lack of histopathological confirmation.

RESUMO

Introducción: la endocarditis infecciosa es una enfermedad que involucra con másfrecuencia las válvulas cardíacas, pero también puede ocurrir sobre cuerdas tendinosas, o el endocardio mural. La lesión característica − vegetación − consiste en una masa de plaquetas, fibrina, microcolonias de microorganismos y escasas células inflamatorias. Objetivo: describir la conducta perioperatoria, así como la evolución clínico-anestesiológica de un paciente que presentó paro cardiaco secundario a insuficiencia mitral aguda por endocarditis bacteriana. Caso clínico: hombre joven con diagnóstico de endocarditis infecciosa e insuficiencia valvular mitral con ruptura de las cuerdas tendinosas, presentó paro cardiorrespiratorio que requirió reanimación cerebrocardiopulmonar con recuperación de la circulación espontánea. Fue llevado al quirófano de emergencia para sustitución valvular mitral y conservación de las cuerdas tendinosas. Se obtuvieron resultados satisfactorios, sin secuelas pulmonares ni neurológicas. Conclusiones: la rápida identificación y tratamiento de la endocarditis bacteriana mejora el pronóstico y evita nefastas complicaciones. La ecocardiografía transesofágica brinda adecuada resolución espacial y precisión en su evaluación y posibilita la mejoría terapéutica(AU)


Introduction: Infectious endocarditis is a disease that involves the heart valves more frequently, but it can also occur on chordae tendineae, or the mural endocardium. The characteristic lesion, vegetation, consists of a mass of platelets, fibrin, microorganisms microcolonies, and few inflammatory cells. Objective: To describe the perioperative behavior, as well as the clinical anesthesiological evolution of a patient who presented cardiac arrest secondary to acute mitral regurgitation due to bacterial endocarditis. Clinical case: A young man with a diagnosis of infective endocarditis and mitral valve insufficiency with ruptured tendinous cords presented cardiorespiratory arrest requiring brain and cardiopulmonary resuscitation with spontaneous circulation recovery. He was taken to the emergency operating room for mitral valve replacement and chordae tendineae conservation. Satisfactory results were obtained, without pulmonary or neurological sequelae. Conclusions: The quick identification and treatment of bacterial endocarditis improves prognosis and prevents nefarious complications. Transesophageal echocardiography provides adequate spatial resolution and accuracy in its evaluation and gives the possibility for therapeutic improvement(AU)

RESUMO

Heart valve disease is a clinical problem that has been studied with classical imaging techniques like echocardiography and MRI. Technological advances in CT make it possible to obtain static and dynamic images that enable not only a morphological but also a functional analysis in many cases. Although it is currently indicated only in patients with inconclusive findings at echocardiography and MRI or those in whom these techniques are contraindicated, multidetector CT makes it possible to diagnose stenosis or regurgitation through planimetry, to evaluate and quantify valvular calcium, and to show the functional repercussions of these phenomena on the rest of the structures of the heart. Given that multidetector CT is being increasingly used in the diagnosis of ischemic heart disease, we think it is interesting for radiologists to know its potential for the study of valvular disease.
