Key result
Cardiac MRI successfully detects a silent thrombus within a rudimentary LV after Fontan palliation.
Why the study?
Thrombosis is a major concern in patients after Fontan surgery, with a reported prevalence of 5-33%, but silent thrombus in a rudimentary left ventricle is rarely reported.
Highlights the role of cardiac MRI in diagnosing silent intracardiac thrombus in patients with Fontan palliation and hypoplastic left ventricle.
May support targeted cardiac MRI in Fontan patients; hypothesis-generating and should not yet change practice.
Thrombosis, especially in the Fontan pathway, is one of the major concerns in patients who underwent Fontan surgery, with reported prevalence of 5-33%. We report a case of thrombus in a rudimentary left ventricle in teenager with no arrhythmia or neurological complications. We also report the special concerns of silent thrombus and role of cardiac MRI in diagnosing an intracardiac thrombus.
