“…The right sinus venosus valve mostly involutes and it's remnants are observed as eustachian valve or thebasian valve. 1 , 2 , 3 The right valve of the sinus venosus goes from the lateral margin of the superior vena cava to the orifices of the inferior vena cava (IVC) and coronary sinus (CS). 4 , 5 , 6 In foetal stage, function of the right valve of the sinus venosus is to direct oxygenated venous return from the IVC via the foramen ovale (FO) to the left chamber of the heart.…”

“…This right atrial network may occasionally mimic thrombus, vegetation or mass. [13][14][15][16] From the therapeutic point of view, Chiari network has been reported to be associated with thromboembolism, 7 infective endocarditis, 6 arrhythmia, 7 and others. Contrarily, the sieve-like structure of Chiari network might play protective role against migration or propagation of thrombus formed in IVC to cause pulmonary embolism.…”

Background: The Chiari network is mobile, serpentine, filament-like structures occasionally seen in right atrium near the opening of inferior vena cava and coronary sinus. Sometimes it may cause diagnostic confusion with right atrial pathologies. Methods: This was a cross sectional study conducted from September 2017 to August 2018 in a private consultation center in Dhaka. All patients who underwent transthoracic echocardiography were included. Chiari network was diagnosed and any relevant clinical condition was recorded. Results: Out of 1832 echo studies, Chiari network was found in 90 subjects giving a prevalence of 4.91%. More than half (55.6%) had otherwise normal heart, 20% had ischaemic heart disease, 7.8% had cardiomyopathy, 6.7% congenital heart disease, while 3.3% had valvular heart disease. Conclusion: The Chiari network is often an incidental diagnosis, though it may not be so rare. Clinicians should be aware of it to avoid diagnostic dilemma and to overcome difficulties while performing cardiovascular interventions. Cardiovasc. j. 2019; 11(2): 93-97

“…Two other structures are frequently found in the right atrium including the Thebesian valve, which can be present at the entrance of the coronary sinus, as well as both the Eustachian valve and Chiari network, which originate at the junction of the IVC and right atrium. 13 The ascending aorta starts at the aortic root and travels from right to left to become the aortic arch. As the arch turns in the caudal direction, the thoracic descending aorta is formed until it reaches the diaphragm where is becomes the abdominal aorta (Fig.…”
