ABSTRACT

O implante de prótese valvar aórtica por cateter (TAVI, do inglês transcatheter aortic valve implantation) constitui o tratamento de escolha para pacientes com estenose aórtica considerada inoperável e surge como opção terapêutica à cirurgia em indivíduos com alto e moderado risco operatório. Embora excelentes resultados clínicos sejam obtidos com as próteses primeiramente disponibilizadas para uso clínico, a ocorrência de complicações ­ como acidente vascular cerebral (AVC), regurgitação (leak) paraprotética, distúrbios de condução com implante de marca-passo (MP) e complicações vasculares ­ deve ser prevenida. As novas próteses têm como características primordiais: menor calibre dos instrumentais, implante valvar mais seguro e previsível e a incorporação de características no arcabouço das próteses que reduzam a ocorrência de refluxo paravalva


Transcatheter aortic valve implantation (TAVI) is the treatment of choice for patients with aortic stenosis that is considered inoperable, and has emerged as a treatment option to surgery in individuals with high to moderate surgical risk. Although excellent clinical results have been obtained with the prostheses primarily provided for clinical use, the occurrence of complications ­ such as cerebral stroke, paraprosthetic regurgitation (leak), pacemaker (MP) implant conduction disorders, and vascular complications ­ should be prevented. The main characteristics of the new prostheses are: narrower instruments, a safer, more predictable valve implant, and the incorporation of characteristics in the framework of the prostheses that reduce the occurrence of paravalvular leaks

ABSTRACT

This study was performed by echocardiography to assess the degree of aortic regurgitation [AR] before and after percutaneous balloon mitral valvuloplasty [PBMV] in patients with mitral stenosis [MS] and associated mild to moderate aortic regurgitation. A total of 60 patients with symptomatic mitral stenosis and mild to moderate aortic regurgitation aged 18-65 years underwent balloon mitral valvuloplasty and the degree of aortic regurgitation was assessed by echocardiography before and after the procedure. Successful PBMV was done with significant increase in the mitral valve area and decrease in both mean and maximum pressure gradient across the mitral valve and systolic pulmonary artery pressure. There was no significant increase in aortic regurgitation severity after PBMV. The severity of AR is not increased after PBMV in patients with MS and associated mild to moderate AR

ABSTRACT

Valvular Heart Disease (VHD) is an important cardiovascular problem in the adult population. The knowledge of the physiology involved, prompt recognition and diagnosis are of paramount importance for the primary care physician who is in the front line of patient care. This article is the second of a series of two that deals with valvular problems in the adults in concise and practical form (11). Each topic will be presented using the following format: description, etiology, pathophysiology, natural history, essential of diagnosis and management. In this second and final article we will discuss aortic valve disorders.

ABSTRACT

O tratamento das valvopatias deve sempre considerar o dano secundário ao miocárdio. Na indicação cirúrgica, deve-se sempre avaliar judiciosamente a evolução da disfunção ventricular, ocasionada pela remodelação e pela fibrose intersticial. Se não for corrigida em tempo adequado, a valvopatia irá se comportar, no futuro, como verdadeira "miocardiopatia". Após a correção da valvopatia existe o remodelamento reverso, com melhora da função global do coração. O grau desse remodelamento reverso relaciona-se com o prognóstico pós-operatório. O atual arsenal terapêutico dos inibidores da enzima de conversão, betabloqueadores, inibidores da angiotensina II e aldactone desempenha um papel na melhora da remodelação reversa no pós-operatório.

ABSTRACT

La insuficiencia aórtica es una valvulopatía producida por múltiples entidades que van a desencadenar un proceso fisiopatológico común, el cual finalmente producirá daño miocárdico, aparición de síntomas y desarrollo de mortalidad. El manejo de esta patología va dirigido inicialmente a retardar el desarrollo de daño miocárdico con el uso de vasodilatadores, pero una vez este se ha desarrollado o, el paciente presenta síntomas, se debe realizar el tratamiento definitivo que corresponde al cambio valvular aórtico. El médico debe estar en capacidad de realizar un adecudo seguimiento para detectar precozmente los indicios del desarrollo de disfunción ventricular izquierda con el fin de indicar el reemplazo valvular pero, si dicha disfunción ya se ha desarrollado no se debe contraindicar por este solo motivo el tratamiento quirúrgico

ABSTRACT

El reemplazo valvular aótico en patología aórtica pura determinada una mejoría inmediata y muy significativa del FE, asi como también del la función. La mortalidad operatoria es muy aceptable y guarda un relación directa con el EF avanzado y con el grado de depresión de la FE del IV. Esta mortalidad puede ser reducida mucho mas si los pacientes son referidos para su intervención mas preocozmente antes que se necuntren en el FE IV y antes de que la función sistólitica del IV medida por la FE este severamente comprometiada como courría en los dos casos que fallecieron.
