Dilated right coronary sinus identified on point-of-care ultrasound

Point-of-care cardiac ultrasound (POCUS) is a common application in Emergency Medicine. Here we present a case of an incidentally discovered dilated right coronary sinus on ultrasound. This case involved a 55-year-old female who presented with chest pain, shortness of breath, and lightheadedness. He...

Description
Summary:Point-of-care cardiac ultrasound (POCUS) is a common application in Emergency Medicine. Here we present a case of an incidentally discovered dilated right coronary sinus on ultrasound. This case involved a 55-year-old female who presented with chest pain, shortness of breath, and lightheadedness. Her initial presentation was concerning for congestive heart failure (CHF) exacerbation. A bedside ultrasound was performed to assess cardiac function, where a dilated right coronary sinus was discovered. The right coronary sinus is the vein that serves as the venous return for the coronary system. It is a tubular structure located at the posterior atrioventricular groove and it is generally not visible unless it is pathologically dilated. Identification of a dilated right coronary sinus can assist the clinician in making the diagnoses of CHF exacerbation, as well as alter the approach to specific procedures. To the best of our knowledge, this is the first case report describing the identification of a dilated right coronary sinus using POCUS.
