Multimodality images of a giant blood cyst originating from the bicuspid aortic valve.

چکیده
A 22-year-old male patient was admitted to our institution because of repeated chest pain and syncope. Physical examination was unremarkable except for a systolic murmur on cardiac auscultation. Transesophageal echocardiogram showed a large, very mobile cystic mass (21×17 mm) attaching to the bicuspid aortic valve, which caused severe left ventricular outflow tract obstruction with normal ventricular size and function (Figure 1A and 1B and Movies I and II in the online-only Data Supplement). Additional cardiac MRI revealed there was a cyst-like mass attached on the aortic valve (Figure 1C through 1E and Movie III in the online-only Data Supplement). Finally, a bluish blood-filled cyst (23×17 mm) originating from the bicuspid aortic valve with a broad base was confirmed during surgical operation (Figure 2A and 2B). Surgical resection of the cyst with concurrent aortic valve replacement was done for this patient. Additional histological examination confirmed that the cystic cavity was surrounded by a fibromyxoid wall with an internal lining of endothelial cells (Figure 2C). The patient was discharged uneventfully 7 days after surgery. Cardiac cyst originated from bicuspid aortic valve is an extremely rare type of cardiac mass. It may cause obstruction of the left ventricular outflow tract (and lead to progressive damage of the valve leaflet itself. Multimodality imaging including echocardiography and cardiac MRI plays an essential role in perioperative evaluation for this rare condition.

Bicuspid Aortic Valve: An Unusual Cause of Aneurysm of Left Coronary Sinus of Valsalva
Bicuspid aortic valve is traditionally considered an innocuous congenital anomaly. Due to a better and widespread availability of non-invasive imaging techniques, it has come to the fore that 30% of these cases develop complications, viz., valve abnormality (aortic regurgitation and stenosis), and aneurysm of aortic root and ascending aorta. Sinus of Valsalva aneurysm is an uncommon complicatio...

Painless Aortic Dissection—Diagnostic Dilemma With Fatal Outcomes: What Do We Learn?
Aortic dissection is the most catastrophic clinical condition that involves the aorta. It has a high mortality as well as high rate of misdiagnosis due to frequent unusual presentation. Typically, it presents with acute chest, back, and tearing abdominal pain. However, it can present atypically with minimal or no pain, making diagnosis difficult. Physicians should always suspect acute aortic di...

We present an unusual case of an intracardiac Eustachian valve cyst observed concurrently with atresia of the coronary sinus ostium, a persistent left superior vena cava (LSVC) and a bicuspid aortic valve. There have been several echocardiographic reports of Eustachian valve cysts; however, there is no report of multidetector computed tomography (MDCT) findings related to a Eustachian valve cys...

A patient who had undergone closure of the perimembranous ventricular septal defect and aortic valve replacement for bicuspid aortic valve with a mechanical prosthesis was being admitted to our department. He was afebrile, blood cultures were negative and there was no sign of endocarditis. Transthoracic echocardiogram showed a normally functioning aortic prosthesis with a aortic root by the occ...
