Abstract:
We describe what we believe to be the first reported case of a neonate with right coronary ostial atresia with the right coronary artery originating from the left circumflex coronary artery, in conjunction with a right coronary artery to right ventricle fistula in a patient with otherwise normal cardiac anatomy. This was found following an evaluation for a continuous murmur at 2 weeks of life with elevated troponin and abnormal electrocardiogram. Thus far the child has required no intervention and is asymptomatic at 17 months of age, but he will require long-term follow-up to monitor the size of the fistula and potential for myocardial insufficiency.

Heart Sounds
Auscultation is the process of listening to these internal body sounds using a stethoscope. The heart produces four types of sounds, but only two—S1 and S2—can usually be heard with a stethoscope.
S1, also known as the "lub" sound, is caused by the closure of atrioventricular (A-V)...

Assessment of the Abdomen I: Inspection and Auscultation
The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.
Inspection of the Abdomen
The first step in any abdominal examination is inspection....
