Presentation
Chiari networks are present in the right atrium in a minority of the population and are usually of no clinical significance. [ncbi.nlm.nih.gov]

In congenital heart disease cyanosis is generally due to right to left shunting through congenital cardiac defects, bypassing the pulmonary alveoli, or due to acquired intrapulmonary shunts (central cyanosis). [cachnet.org]

Withdrawn
When the cannula is withdrawn slightly, the fibers appear snagged to its tip. The balloon is often not easily visualized because of thin wall and filling with saline/blood cardioplegia, which has similar acoustic properties to blood. [journals.lww.com]

Excitement
Some dream of meeting their favorite celebrity, enjoying the fun and thrills of a theme or amusement park, traveling to an exciting destination, being a VIP on a day of shopping, or receiving the latest in electronics. [kidswishnetwork.org]
Electrocardiogram of the patient at presentation showing regular wide-complex tachycardia (left panel), which was reverted to sinus rhythm showing pre-excitation (right panel). [ncbi.nlm.nih.gov]
Workup
As a part of the workup for respiratory distress at the referring hospital, a chest CT scan had been obtained [Figure 1]. [annals.in]

Staphylococcus Aureus
She had a history of infective endocarditis caused by methicillin-sensitive Staphylococcus aureus a year ago. Echocardiography did not reveal the presence of any vegetation on any of the cardiac valves. [ncbi.nlm.nih.gov]
Blocks

2:1 Atrioventricular Block
An 82-year-old woman with 2:1 atrioventricular block underwent a pacemaker implantation procedure, but a tined lead became entrapped by the Chiari network. [ncbi.nlm.nih.gov]
Treatment
Transoesophageal echocardiogram confirmed entrapment of a thrombus within the Chiari network, which was not visualised following treatment on repeat scanning 1 month later. [ncbi.nlm.nih.gov]
Following thrombolytic treatment the right atrial serpiginous thrombus and apical thrombus disappeared. The patient was discharged 10 days later in excellent general condition on oral anticoagulant treatment. [heart.bmj.com]
Surgical treatment was performed forthe mass removal and differential diagnosis of the mass. There was no evidence of other tumor, but Chiari's network. [e-sciencecentral.org]
Prognosis
Treatment and prognosis A cor triatriatum is usually fatal within the first two years of life. The membrane can be surgically resected. [radiopaedia.org]

Although the paradoxical embolism following Chiari network is uncommon, the characteristics of the Chiari network described here might explain the pathophysiology of a paradoxical embolism [4]. Also, how to deal with Chiari network is controversial. [oatext.com]

Prevention
The network perhaps functioned as an inferior vena cava filter preventing massive pulmonary embolus. [ncbi.nlm.nih.gov]
Also preventing from right atrium catheter implantation, pace wire lead insertion and CPB cannulation are related to Chiari network [12-14]. In thrombophilia it acts such as inferior vena cava filter and prevents emboli [15]. [oatext.com]
