A EchoTalker descobriu um bom motivo para você ter um 3D

Seu ombro!

A fadiga muscular diminuiu 80% com o Apical 4C sem rodar ou mudar

Fácil demais

Nem vamos falar do 3D volume total

Falamos dos cortes 2D que todos aceitam

Só conseguir um 4C no apical e soltar a máquina

Machine-Learning Algorithms to Automate Morphological and Functional Assessments in 2D Echocardiography

Os métodos de aprendizado de máquina não descartam o valor da avaliação ecocardiográfica convencional para diferenciar as doenças cardiovasculares; em vez disso, oferece oportunidades para simplificar o processo de diagnóstico, fornecendo uma solução contemporânea de integração do número crescente de parâmetros de imagem em um banco de dados de imagem clínica

Methods

Based on the echocardiographic findings at the time of diagnosis of moderate AS (aortic valve area between 1.0 and 1.5 cm² and dimensionless velocity index ratio of ≥0.25), a total of 1,245 patients were included and analyzed retrospectively. They were recategorized into 5 groups according to the extent of extra-aortic valvular cardiac abnormalities: none (Group 0), involving the left ventricle (Group 1), the left atrial or mitral valve (Group 2), the pulmonary artery vasculature or tricuspid valve (Group 3), or the right ventricle (Group 4). Patients were followed for all-cause mortality and combined endpoint (all-cause mortality, stroke, heart failure, or myocardial infarction).

Results

The distribution of patients according to the proposed classification was 13.1%, 26.8%, 42.6%, 10.6%, and 6.9% in Groups 0, 1, 2, 3, and 4, respectively. During a median follow-up of 4.3 (2.4 to 6.9) years, 564 (45.3%) patients died. There was a significant higher mortality rates with increasing extent of extra-aortic valvular cardiac abnormalities (log-rank p < 0.001). On multivariate analysis, the presence of extra-aortic valvular cardiac abnormalities remained independently associated with all-cause mortality and combined outcome, adjusted for aortic valve replacement as a time-dependent covariable. In particular, Group 2 and above were independently associated with all-cause mortality.

Conclusions

In patients with moderate AS, the presence of extra-aortic valvular cardiac abnormalities is associated with poor outcome.

A importância de um bom exame de ecocardiografia nas valvopatias é inegável.
