Fibrosis, Valvular and Ventricular Function in Patients With Transposition of the Great Arteries

Brief Summary

      The aim of this project is to better evaluate the systemic right ventricular (RV) function in
      patients with transposition of the great arteries (TGA).

Detailed Description

      Patients with TGA frequently develop supraventricular and ventricular arrhythmia, conduction
      problems, systemic atrioventricular valve (SAVV) regurgitation, and congestive heart failure
      (CHF), all at young age. However, there is variation in time of onset of these adverse
      events. We want to evaluate ventricular and valvular function at rest, markers of RV fibrosis
      and cardiac reserve.

Study Type


Primary Outcome

Correlation between fibrosis and systemic right ventricular (RV) function

Secondary Outcome

 Correlation between systemic RV function and systemic atrioventricular valve (SAVV) regurgitation ≥3/4

             resting systolic blood pressure > 200 mm Hg and/or diastolic blood pressure > 110 mm
             Hg, New York Heart Association (NYHA) class III or IV, or non-cardiac co-morbidity
             that could aggravate by exercise
