Introduction

This is an online calculator modeled after the CHOP fetal cardiovascular profile scoring system proposed in:

The twin-twin transfusion syndrome: spectrum of cardiovascular abnormality and development of a cardiovascular score to assess severity of disease.

Am J Obstet Gynecol 2007;197:392.e1-392.e8.

• CHOP Fetal CV Profile Score Calculator

Details

The score rates various indices of both donor and recipient cardiovascular performance/remodeling, as measured by fetal echo:

• Donor
• umbilical artery flow, as a marker of placental vascular resistance

• Recipient
• cardiac size and ventricular hypertrophy
• ventricular function
• tricuspid and mitral reguritation
• inflow Doppler characteristics
• ductus venosus and umbilical venous flows, as markers of ventricular compliance
• RV outflow obstruction
• pulmonary valve insufficiency

The only calculations involved are the sum of the various individual scores and the subsequent grading of of the total score- from '1' to '4'.
