CASE REPORT
A 13-year-old male patient, applied to pediatric cardiology at the outer center with chest pain 3 months ago. In transthoracic echocardiography performed there, 1st degree aortic regurgitation was detected, and secondary penicillin G prophylaxis was initiated considering the insidious rheumatic carditis. Laboratory tests performed in the outer center at that time were normal. The patient applied to our outpatient clinic for his second control, and he did not have any complaints. An anamnesis taken by us revealed that there was no history of acute rheumatic fever (ARF) in any period. The patient’s physical examination was completely normal. In laboratory examination, hemogram, biochemical parameters, acute phase reactants and anti-streptolysin O titre were normal. 12-lead electrocardiogram (ECG) was normal. On transthoracic echocardiography, the aortic valve was quadriquspid (Figure 1) and there was a 1st degree aortic regurgitation (Figure 2). The patient was diagnosed with quatricuspid aortic valve and it was thought that aortic regurgitation was due to valve anomaly. Secondary penicillin prophylaxis, which was started for rheumatic carditis in the outer center, was stopped. The patient was followed up at regular intervals.
