Is echocardiography valid and reproducible in patients with atrial fibrillation? A systematic review

- The new 2016 ESC Guidelines on AF recommend echocardiography in all AF patients to guide management (I C).
- In this systematic review, data on the validity and reproducibility of systolic indices in AF patients were extremely limited; the best measure of systolic function and acquisition method in AF are priorities for future research.
- Diastolic parameters in AF have been validated against invasive filling pressure with adequate reproducibility. Elevated E/e’ (>15) is also associated with functional capacity, quality of life, and impaired prognosis.
- Measurement of systolic and diastolic function in AF is optimized when the two preceding cardiac cycles have similar RR-intervals and the heart rate is controlled (<100 beats/min).

Erros comuns:
Subestimar a fração de ejeção
Superestimar o refluxo mitral
Confundir o grau de disfunção diastólica
Superestimar a pressão pulmonar
Detectar alterações segmentares irreais
Superestimar a estenose mitral
