Intraventricular muscle bundle as a novel cause of left ventricular aneurysm
Abstract Background There are a variety of causes of left ventricular aneurysm, but it is rarely due to a disturbance in intraventricular hemodynamics. To the best of our knowledge, there have been no reports of ventricular aneurysm at the left ventricular apex caused by an abnormal left ventricular...

| description | Abstract Background There are a variety of causes of left ventricular aneurysm, but it is rarely due to a disturbance in intraventricular hemodynamics. To the best of our knowledge, there have been no reports of ventricular aneurysm at the left ventricular apex caused by an abnormal left ventricular muscle bundle. Case presentation We report two cases of patients with congenital abnormal left ventricular muscle bundles which caused disturbances in intraventricular hemodynamics. This process eventually led to a left ventricular aneurysm at the apex of the heart. In both cases, transthoracic echocardiography (TTE) and cardiac magnetic resonance imaging (CMR) indicated ventricular aneurysm formation at the apex of the left ventricle. There were also abnormal muscular bundles connecting the ventricular septum and the posterior wall of the left ventricle. The only differences between these two cases were the comorbidities and severity of symptoms. Conclusion Ventricular aneurysm at the apex of the left ventricle is common. However, it is rare for a ventricular aneurysm to form due to intraventricular hemodynamic disturbances caused by an abnormal muscle bundle as opposed to that due to original ventricular wall damage, which is more common. There is currently a lack of relevant studies on the treatment and prognosis of such patients. Whether surgical resection of a ventricular aneurysm leads to a better prognosis remains uncertain. |
