Sinotubular junction | Radiology Reference Article | Radiopaedia.org
The sinotubular junction (STJ) is the region of the ascending aorta between the aortic sinuses (of Valsalva) and where the normal tubular configuration of the aorta is attained.

Sinotubular Junction - Radiology In Plain English
The Sinotubular Junction (STJ) serves as a connection point between the aortic root and the ascending aorta. It’s an important area where the aortic valve joins the aorta, facilitating the flow of oxygen-rich blood from the heart to the rest of the body.

Sinotubular junction (STJ) - Clinical Anatomy
The sinotubular junction (STJ) is a well-defined circular ridge found between the superior or tubular segment of the ascending aorta and the inferior, bulbous segment of the ascending aorta, known as the aortic root.

Anatomy of the aortic root: implications for valve-sparing surgery
The distal part of the sinuses toward the ascending aorta together with the commissures form a tubular structure called the “sinotubular junction” which separates the aortic root from the ascending aorta (Figure 1) (14).

Aortic Anatomy - E-Echocardiography
The geometry of the sinotubular junction is important for the normal function of the aortic valve apparatus. The aortic valve cusps insert from the aortic annulus to the sinotubular junction.

18.10B: Ascending Aorta - Medicine LibreTexts
The sinotubular junction is the point in the ascending aorta where the aortic sinuses end and the aorta becomes a tubular structure. At the junction of the ascending aorta with the aortic arch, the caliber of the vessel increases with a bulging of its right wall.

Sinotubular junction diameter - e-Anatomy - IMAIOS
The sinotubular junction (or “sinotubular ridge”) is the part of ascending aorta where the sinuses taper superiorly and meet the tubular ascending aorta. Normative reference value of sinotubular junction: 22-36 mm (15±1mm/m²)

The site where the bulbous portion of the aorta meets the narrower tubular-shaped aorta is termed sinotubular junction. Effacement of this junction suggests annuloaortic ectasia and often is seen in patients with Marfan syndrome.

Thoracic aortic aneurysm: How to counsel, when to refer
The sinotubular junction marks the boundary between the root and the tubular ascending aorta. This transition point can be affected by aneurysmal disease; some aneurysms efface it, leading to loss of normal tapering in size from the root to the ascending aorta.
