Key result
Restrictive RV physiology after TOF repair reduces cardiac output and elevates CVP, driving multiorgan consequences.
Why the study?
Restrictive right ventricular physiology frequently occurs after surgical repair of tetralogy of Fallot and leads to reduced cardiac output, elevated central venous pressure, and multiorgan consequences.
This review outlines the pathophysiology, end-organ consequences, and management of restrictive right ventricular physiology in children following tetralogy of Fallot repair.

May prompt closer post-TOF surveillance for multiorgan effects; extends pathophysiologic framework while leaving targeted interventions open.
Restrictive right ventricular physiology (RRVP) occurs due to impaired right ventricular compliance and associated diastolic dysfunction. This results in reduced cardiac output and elevated central venous pressure with downstream consequences for the liver, kidneys, gut, and lymphatic system. RRVP is frequently seen after surgical repair of tetralogy of Fallot (TOF), though it occurs across a range of congenital heart defects with long‐standing RV pressure overload. This review provides a clinically oriented description of the pathophysiology, patients at risk, end‐organ consequences, and management of RRVP in the immediate post‐operative period after TOF repair.

Aldawsari et al. (2026) conducted a review in Restrictive right ventricular physiology after tetralogy of Fallot repair. Restrictive right ventricular physiology was evaluated. Restrictive right ventricular physiology after tetralogy of Fallot repair results in reduced cardiac output and elevated central venous pressure with downstream multiorgan consequences.
