Tricuspid inflow velocity tamponade
WebInspiratory decrease in mitral inflow E-wave velocity >25%. 2. Expiratory decrease in tricuspid inflow E-wave velocity >40%. 3. Hepatic veins: expiratory increase in diastolic flow reversal. 4. Superior vena cava forward flow is predominantly systolic, with decrease or loss of the diastolic component and increased flow reversals on expiration. 5. WebMar 9, 2015 · The reduction in left heart filling during inspiration causes a reduction in mitral inflow velocity and a shift of the interventricular septum toward the left ventricle. With expiration, left heart filling increases which shifts the interventricular septum back toward the right ventricle, leading to reduced filling to right side of the heart and a late-diastolic …
