Coarctation of the Aorta and Late-Onset Sepsis With Supraventricular Tachycardia: A Clinical Case Review.

We report a case of an 11-day-old male infant who presented to our hospital with complaints of breathing difficulty and cough for two days prior to admission. The child had a seizure post-admission which was controlled with phenobarbitone. The child was connected to a mechanical ventilator. The baby also had persistent tachycardia, which upon doing an electrocardiogram (ECG) led to a diagnosis of supraventricular tachycardia (SVT). Additional investigations revealed the existence of late-onset sepsis (LOS), which was treated with appropriate antibiotics. In view of weak femoral pulses with normal brachial pulses, a diagnosis of coarctation of the aorta (CoA) was entertained. The diagnosis was confirmed by an echocardiogram, and the baby was transferred to a higher-level medical center for surgical correction. Regrettably, the baby succumbed to heart failure and shock on the 12th day of life. This case highlights the infrequency of CoA accompanied by SVT. The case delves into the challenges of diagnosing the condition, the necessary medical interventions, and the unforeseen complications that must be considered to reduce mortality in such circumstances.
