Windsock pattern
Windsock pattern or windsock lesion is one of the signs of left ventricular outflow tract aneurysm.

# Diagnosis

## Echocardiography

- Sinus of Valsalva Aneurysm: Gross; a beautiful picture of windsock opening of aneurysm beneath anterior leaflet of tricuspid valve into right ventricle
- Sinus of Valsalva Aneurysm: Gross; an excellent picture; cut through aneurysm.
- Sinus of Valsalva Aneurysm: Gross; An infected aneurysm with a ruptured aortic cusp due to endocarditis.
- Sinus of Valsalva Aneurysm: Gross; difficult to orient but aneurysm is visible.
- Sinus of Valsalva Aneurysm Infected: Gross; natural color, close-up view of coronary cusps with extensive ulceration and fibrinous material. Staphylococcus infection of a bicuspid valve.
- Sinus of Valsalva Aneurysm Infected: Gross; natural color fibrin exudate and some valve scarring are easily seen but aneurysm not seen. The bicuspid valve requires careful look to appreciate Staphylococcus caused lesion.
- Ruptured Sinus of Valsalva Aneurysm: Gross; natural color view from left atrium of left sinus aneurysm that is pointing into left atrium through mitral ring at anterior mitral commissure (the most unusual lesion).
- Ruptured Sinus of Valsalva Aneurysm: Gross; natural color view of left ventricular outlet with hemorrhagic lesion in left coronary sinus.
- Ruptured Sinus of Valsalva Aneurysm: Gross; natural color close-up of aneurysm in aortic valve.
- Sinus of Valsalva Aneurysm: Gross fixed tissue shows aneurysm in noncoronary cusp about as well as possible see for picture with probe in aneurysm
- Sinus of Valsalva Aneurysm: Gross fixed tissue close-up view with probe in non coronary sinus aneurysm see for photo without probe
- Sinus of Valsalva Aneurysm Ruptured: Gross fixed tissue view of right side of heart showing site of rupture below tricuspid ring also patent foramen ovale
