Congenital ventricular diverticulum presenting as sustained monomorphic ventricular tachycardia

Abstract

Congenital ventricular diverticulum is a rare congenital cardiac defect. Most patients with this abnormality will remain asymptomatic and without complications during long-term follow-up. However a subgroup of these patients may experience life threatening complications such as ventricular arrhythmias, systemic embolism, sudden death, spontaneous rupture, and valvular regurgitation. We present a case of a patient with a congenital ventricular diverticulum presenting with sustained monomorphic ventricular tachycardia and evaluated by 64-slice CT. This is an uncommon but possibly life threatening arrhythmia described in less than 10 cases in the medical literature. The natural history of such patients as well as the appropriate treatment is unclear. Most of the literature advocates early surgical intervention. We decided to provide the patient with an implantable cardioverter defibrillator (ICD) and not surgical intervention due to the close proximity of the defect to the mitral valve.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
