We found a modest decrease in RVIT dimensions (P < 0.05), but increase in RVOT dimensions with advancing age (P < 0.05). A small decrease in RVOT fs with age was also found (P < 0.05). Estimated pulmonary pressures and pulmonary vascular resistance increased (P < 0.001) as did RVOT wall thickness (P < 0.001), but RV diastolic function was not altered (P < 0.001) with age. Despite correction for the BSA, males showed larger RVIT dimensions (P < 0.001 for both), but RVOT end-diastolic dimension was larger in females (P < 0.05). RVIT and RVOT fractional shortening were increased in females (P < 0.01 for both).
In a cohort of normal individuals, age has significant impact on right ventricular structure and function, inlet area falls and outflow tract dimensions increase and fractional shortening also increase in females. In addition, RV outflow tract wall thickens significantly and Doppler markers of pulmonary vascular resistance show a consistent rise. The age-related changes should carefully be considered when commenting on normality and when using absolute values.
Vemos frequentemente laudos patológicos e conclusões com cinco ou mais linhas, em pacientes acima de 65 anos.
Muitos dos achados são comuns na faixa etária e não deveriam ser abordados na conclusão.
Envelhecer não é uma condenação certa à doença. O laudo de ecocardiografia deve respeitar a fisiologia e não assustar pacientes e médicos solicitantes!
