Right Ventricular Function Evolution With Pregnancy in Repaired Tetralogy of Fallot

Area of Science:

• Cardiology
• Echocardiography
• Congenital Heart Disease

Background:

• Tetralogy of Fallot (TOF) is a complex congenital heart defect.
• Repaired TOF requires lifelong cardiovascular monitoring.
• Pregnancy places unique hemodynamic stress on the cardiovascular system.

Observation:

• This case study tracked right ventricular (RV) 3-dimensional (3D) area strain during pregnancy.
• The patient had a history of surgically repaired Tetralogy of Fallot.
• Changes in RV function were monitored throughout gestation.

Findings:

• Pregnancy was associated with a decline in RV systolic function.
• RV 3D area strain analysis revealed functional impairment.
• The study observed a worsening of RV performance during pregnancy.

Implications:

• Pre-pregnancy RV systolic function assessment is vital for managing pregnant patients with repaired TOF.
• 3D echocardiography offers a valuable tool for evaluating RV function in this population.
• Early identification of RV dysfunction can guide clinical management and improve outcomes.
