The coronary sinus (CS) has been largely ignored by physicians due to a lack of adequate data about the importance of CS enlargement in patients with heart failure (HF). We aimed to assess whether CS dilatation develops in patients with HF and to ...

2015年7月12日 · Its recognition is important when an enlarged coronary sinus occurs and consequently a differential diagnosis must be made. PLSVC should always be suspected in presence of a dilated coronary sinus, incidentally discovered by echocardiography.

An echo-free structure in the posterior atrioventricular groove suggested an enlarged coronary sinus, which was confirmed in parasternal long-axis view (Fig. 1) and modified apical 4-chamber view with posterior tilt (Fig. 2). The mitral valve area was 0.6 cm 2 by planimetry.

2024年10月27日 · The coronary sinus is the largest cardiac venous structure. It returns the majority of the blood supply for the left ventricle to the right atrium. The coronary sinus courses along the posterior wall of the left atrium into the left atrioventricular groove. It normally drains into the right atrium.

The coronary sinus (from Latin corona 'crown' [citation needed]) is the largest vein of the heart. [1][2] It drains over half of the deoxygenated blood from the heart muscle into the right atrium.

Coronary sinus dilation was observed in 81% of a selected group of patients with pulmonary hypertension in the absence of structural disease of the tricuspid valve. Coronary sinus dilation is related to RAP and RA size, but not to RV size, degree of TR, RVP, PA pressure, or PVR.

We report a patient with persistent left superior vena cava with an enlarged coronary sinus and normal right superior vena cava. Keywords: Vena cava superior, Echocardiography, Coronary sinus. Persistent left superior vena cava (PLSVC) is a rare venous abnormality.

2022年11月17日 · What is the coronary sinus? The CS is a large coronary vein that measures between 3–5 centimeters (cm) in length and 1–2 cm in diameter. This large venous structure is responsible for...

2023年11月3日 · The coronary sinus is the largest cardiac venous structure. It arises from the confluence of the oblique vein (of Marshall) of left atrium and the great cardiac vein. The sinus then courses for about 2 or 3 cm within the inferior atrioventricular groove, between the left atrium and left ventricle.

2012年11月23日 · Therefore, the presence of unroofed coronary sinus syndrome is highly probable in patients with an enlarged coronary sinus without PLSVC. However, patients with right atrial hypertension or anomalous pulmonary venous connection with the coronary sinus may have an enlarged coronary sinus.
