An Alternative Method to Calculate Simplified Projected Aortic Valve Area at No...
Ferreira,Joana Sofia Silva Moura; Moreira,Nádia; Ferreira,Rita; Mendes,Sofia; Martins,Rui; Ferreira,Maria João; Pego,MarianoAbstract Background: Simplified projected aortic valve area (EOAproj) is a valuable echocardiographic parameter in the evaluation of low flow low gradient aortic stenosis (LFLG AS). Its widespread use in clinical practice is hampered by the laborious process of flow rate (Q) calculation. Objetive: This study proposes a less burdensome, alternative method of Q calculation to be incorporated in the original formu...

Lowering Pulmonary Wedge Pressure after Heart Transplant: Pulmonary Compliance ...
Moreira,Nádia; Baptista,Rui; Costa,Susana; Franco,Fátima; Pêgo,Mariano; Antunes,ManuelAbstractBackground:Right ventricular (RV) afterload is an important risk factor for post-heart transplantation (HTx) mortality, and it results from the interaction between pulmonary vascular resistance (PVR) and pulmonary compliance (CPA). Their product, the RC time, is believed to be constant. An exception is observed in pulmonary hypertension because of elevated left ventricular (LV) filling pressures.Objecti...
