Two cases of inferior myocardial infarction associated with anomalous origin of the right coronary artery from the left sinus of Valsalva are described.
Sinus of Valsalva aneurysms are rare cardiac anomalies which may be acquired or congenital, most commonly involving the right or noncoronary sinuses. The congenital aneurysms are more common and often caused by weakness at the junction of the aortic media and the annulus fibrosus. Acquired aneurysms are caused by conditions affecting the aortic wall, such as infections (syphilis, bacterial endo...
We describe a patient with an unusual coronary anatomic variant in which the heart was supplied by a single coronary artery arising above the left sinus of Valsalva.
BACKGROUND The Valsalva manoeuvre is an internationally recommended treatment for supraventricular tachycardia, but cardioversion is rare in practice (5-20%), necessitating the use of other treatments including adenosine, which patients often find unpleasant. We assessed whether a postural modification to the Valsalva manoeuvre could improve its effectiveness. METHODS We did a randomised cont...
BACKGROUND Right-sided infective endocarditis is uncommon. This is primarily seen in patients with intravenous drug use, pacemaker or central venous lines, or congenital heart disease. The vast majority of cases involve the tricuspid valve. Isolated pulmonary valve endocarditis is extremely rare. We report the first case of a pulmonary valve nonbacterial thrombotic endocarditis caused by right ...
An 8-year-old girl with Williams syndrome was found to have a heart murmur. Cardiac CT demonstrated a Valsalva sinus aneurysm (VSA) of the non-coronary cuspid, with left atrium (LA) indentation, resembling the face of Cyclops on a coronal reformatted image. Williams syndrome is related to some congenital disorders with interruption of the tunica media from the aortic root to the annular fibrous...
