Outcomes of total surgical correction for tetralogy of fallot in Benghazi

Abstract EN

Tetrology of Fallot (TOF) is the most common cyanotic congenital heart disease, ac- counting for 10% of all types of congenital heart disease.

Despite decreased mortality rates by im- provement in surgery and post-cardiac intensive care, there continues to be late postoperative com- plications.

This study aimed to evaluate the outcomes after total repair of tetralogy of Fallot, includ- ing 44 children who underwent complete surgical repair between 2000 to 2018.

Data were collect- ed from medical records and directly from patients during their visit to the clinic, that included: history, clinical examination, gender, age at operation, results of ECG, Holter monitoring, echocar- diography, cardiac catheterization, cardiac CT scan.

Follow-up ranged from 6 months to18 years.

Results revealed that the M/F ratio was 1.4:1.

Also, two patients had a previous palliative systemic artery to PA shunt.

A TAP was inserted in 22 (50%) patients.

Postoperative complications were: severe PR 29%, small residual VSD 18.1%, and two patients had significant VSD which needed surgical intervention, residual RVOT 8.1%, RBBB 97.7%, There was three death (6.8%), and 36.3% of patients will need surgical intervention in the future.

It was concluded that follow-ups up to adulthood to monitor potential complications are necessary.

QRS duration is used for monitoring ventricular arrhythmia and sudden death.

Echocardiography is a non-invasive tool in diagnosis, be- fore and at the time of surgery, as well as in follow-ups.
