Quality of Life in Operated Adult Patients With Tetralogy of Fallot and Correlation With Myocardial Strain Analysis by CMR

"This study involves no experimental intervention. All data were collected retrospectively from patients with repaired Tetralogy of Fallot (TOF) who underwent standard clinical follow-up. As part of routine care, patients received comprehensive multimodal functional assessment, including:~Cardiac Magnetic Resonance Imaging (CMR) with feature-tracking strain analysis~Transthoracic Echocardiography~Exercise stress testing (treadmill ECG using Bruce protocol)~12-lead ECG and 24-hour Holter monitoring~Laboratory evaluation including NT-proBNP levels~NYHA functional class assessment"
