Comparison of Ultrasound with Fluoroscopy to Assess Diaphragmatic Paralysis After Congenital Heart Disease Surgery

Inclusion Criteria: * Patients who had congenital heart disease (CHD) surgery in National Cardiovascular Center Harapan Kita (NCCHK) * Suspected of diaphragmatic paralysis based on clinical symptoms and X-ray examination. The conditions indicating diaphragmatic paralysis in patients after CHD surgery were mechanical ventilation dependence, increased respiratory effort and reduced peripheral oxygen saturation when breathing spontaneously, recurrent respiratory tract infection, and chest X-ray showing right hemidiaphragm \>2 cm higher than left diaphragm or left diaphragm at the same level or higher than right diaphragm Exclusion Criteria: * Patients who could not achieve oxygen saturation targets with the help of minimal pressure support such as continuous positive airway pressure (CPAP) or pressure support intermittent mandatory ventilation (P SIMV) * Refusal from the patient/family to be included in the study * Past medical history of diaphragmatic disorder.
