Prognostic implications of inferior vena cava haemodynamics in ambulatory patients with tetralogy of Fallot.

ABSTRACT:

Aims

Right atrial pressure (RAP) provides a composite measure of right ventricular diastolic dysfunction, right atrial compliance, and volume status, and these three variables are typically abnormal in adults with repaired tetralogy of Fallot (TOF). RAP is a well-established prognostic metric in patients with pulmonary hypertension, and recent data suggest that RAP is associated with clinical outcomes in TOF. The purpose of this study was to determine the role of inferior vena cava (IVC) haemodynamics (size and collapsibility) for the assessment of RAP and its potential application for risk stratification and prognostication in the TOF population.

Methods and results

Adult TOF patients with echocardiographic assessment of IVC haemodynamics were divided into patients with (de
