A 59-year-old male was admitted through the emergency room after falling from a ladder at a height of 12 feet. He sustained multiple fractures including a complicated proximal humeral and radial fracture. His cardiovascular physical examination was significant for a 2/4 diastolic murmur. His admission ECG (Figure 1) showed sinus rhythm with a heart rate of 59 bpm, first degree atrioventricular block and premature atrial contractions. His portable chest x-ray ( Figure 2) was significant for cardiomegaly, multiple rib fractures, and multiple calcifications projecting over the cardiac silhouette. Because of these abnormal findings and in preparation for his orthopedic surgery, the patient underwent a transthoracic echocardiogram, which revealed a massively enlarged aortic root with large sinuses of Valsalva aneurysms measuring Ϸ10 cm in diameter (Figure 3). Moderate to severe aortic regurgitation was present, and left ventricular function was normal. The patient was further evaluated by computerized tomography of the ascending aorta ( Figure 4A and 4B). This imaging modality further confirmed the findings in the echocardiogram. The presence of a layered thrombus was also noted within the dilated sinuses. Because of these features, the coronary arterial anatomy was not reliably imaged.Further investigation revealed a previous aortogram done 3 years previously at a different institution where the patient presented with complaints of mild nonexertional chest discomfort that later subsided. This previous study revealed similar findings of a dilated aortic root that already existed at
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
