A incrível bicicleta Echotalk para ecostress com a mão direita

Beto Matos-Souza

O colega Lamberto Sales fez o curso de ecostress e usa o braço direito!
Usou a cabeça, 400 reais e a bicicleta ficou assim. Pode copiar.
Agora só não faz Eco de esforço quem for ruim da cabeça!

O velho PHT da Mitral.

Mitral valve area by the pressure half-time method does not correlate with mean gradient in mitral valve repair patients

.
Eur J Echocardiogr (2011) 12 (2):124-130.
.
Methods and results Forty-two patients with a repaired mitral valve were identified. Mitral valve area was calculated by both the pressure half-time method and the continuity equation. The two mitral valve areas were then directly compared and also correlated with mean gradient. The two mitral valve areas were significantly different from one another with a mean of 1.81 ± 0.53 cm2 by continuity equation and 2.65 ± 0.69 cm2 by pressure half-time. The continuity equation correlated well with mean gradient (ρ = −0.63), whereas the correlation for pressure half-time was weak (r = −0.08).
.
Conclusion A non-linear, inverse correlation was found between mitral valve area by the continuity equation and mean gradient. No correlation was found between the pressure half-time method for mitral valve area and mean gradient. The continuity equation likely provides a better estimate of mitral valve area in repaired mitral valves.
.
The actual burden of iatrogenic mitral stenosis, following a mitral valve repair, is likely related to the aetiology of the mitral insufficiency, the repair strategy employed, and the size of the annuloplasty product implanted. Incorporating this information into the echocardiography report, along with mean gradient and mitral valve area by the continuity equation, will likely provide an improved understanding of the performance of a repaired mitral valve.

Uma boa pergunta é por que?
Sim, por que após a plastia mitral o PHT passa a funcionar mal?
Já sabemos que para próteses, o PHT também não é eficiente.
Será que a abordagem do anel mitral mexe com a curva de enchimento ventricular e altera o PHT…

The use of pocket-size imaging devices: a position statement of the 

European Association of Echocardiography



Pocket-size imaging devices are a completely new type of echo machines which have recently reached the market. They are very cheap, smartphone-size hand-held echo machines with limited technical capabilities. The aim of this European Association of Echocardiography (EAE) position paper is to provide recommendations on the use of pocket-size imaging devices in the clinical arena by profiling the educational needs of potential users other than cardiologists experts in echo. EAE recommendations about pocket-size imaging devices can be summarized in:

(1) pocket-size imaging devices do not provide a complete diagnostic echocardiographic examination. The range of indications for their use is therefore limited.


(2) Imaging assessment with pocket-size imaging devices should be reported as part of the physical examination of the patient. Image data should be stored according to the applicable national rules for technical examinations.


(3) With the exception of cardiologists who are certified for transthoracic echocardiography according to national legislation, specific training and certification is recommended for all users. The certification should be limited to the clinical questions that can potentially be answered by pocket-size devices. 


(4) The patient has to be informed that an examination with the current generation of pocket-size imaging devices does not replace a complete echocardiogram.

.
As regras estão postas:
1) Esta claro que o exame não é completo.
2) É chamado ecoscópio por isso.
3) O treinamento é fundamental, mas não precisa ser ecocardiografista completo, pois o aparelho é incompleto.
4) Por enquanto, é necessário.
