Diagnostic and interventional cardiac catheterisation performed within the first 72 hours of the postoperative period in congenital heart surgery

Abstract
Cardiac catheterisation in the postoperative period emerges as a primary tool, providing effectiveness and safety in diagnosis, treatment guidance, and resolution of major residual lesions.
This is a retrospective case-control study. We collected the clinical records of patients who underwent cardiac catheterisation between January 2003 and December 2022 within the initial 72 hours after surgery in the pediatric cardiac ICU of a national referral hospital in Mexico City. Descriptive, univariate, and multivariate analyses were performed.
A total of 6,243 surgeries were performed, of which 264 were cardiac catheterizations carried out within the first 72 hours of the postoperative period;these included 73 diagnostic procedures and 191 interventional procedures. One hundred and thirty-five (135) catheterisations targeted recent suture intervention sites. The primary indications for cardiac catheterisation included low cardiac output and the suspicion of major residual lesions. Approximately 65% of interventions occurred within the first 24 hours and solved 426 residual lesions. No significant associations were found between mortality, complications, and the need for surgical reintervention in patients who underwent interventional catheterisation at recent suture sites (OR 1.93;95% CI:0.94–4.07:p = 0.076). Seventeen patients (17) were extubated in the initial 24 hours post-catheterisation. Two major complications were identified: rupture of the systemic-to-pulmonary shunt in the anastomosis, and a pulmonary artery laceration requiring emergency surgery. One patient died.
Cardiac catheterisation has evolved into a vital instrument to diagnose and resolve abnormalities and significant residual lesions without increasing the morbidity and mortality risks.
