Ebstein’s Anomaly, Left Ventricular Noncompaction, and Sudden Cardiac Death

Ebstein's Anomaly, Left Ventricular Noncompaction, and Sudden Cardiac Death

Ebstein's anomaly is a congenital disorder characterized by apical displacement of the septal leaflet of the tricuspid valve. Ebstein's anomaly may be seen in association with other cardiac conditions, including patent foramen ovale, atrial septal defect, and left ventricular noncompaction (LVNC). LVNC is characterized by increased trabeculation within the left ventricular apex. Echocardiograph...

Left ventricular cardiac myxoma and sudden death in a dog

BACKGROUND Myxoma is a very rare benign cardiac tumor in dogs. This is the first description of a cardiac myxoma originating from the left ventricular outflow tract, presumably causing sudden death. CASE PRESENTATION A previously healthy 12-year-old male West Highland white terrier was found dead during its 1-week stay in a kennel. The dog was known to have a cardiac murmur. On necropsy, a pe...

Left Ventricular Diameter and Risk Stratification for Sudden Cardiac Death

BACKGROUND Left ventricular (LV) diameter is routinely measured on the echocardiogram but has not been jointly evaluated with the ejection fraction (EF) for risk stratification of sudden cardiac death (SCD). METHODS AND RESULTS From a large ongoing community-based study of SCD (The Oregon Sudden Unexpected Death Study; population ≈1 million), SCD cases were compared with geographic controls. ...

Hypertension, left ventricular hypertrophy, and sudden cardiac death.

Hypertension (HTN) is the most common cause of hypertensive heart disease, which comprises of left ventricular hypertrophy (LVH), left atrial enlargement, diastolic dysfunction, functional mitral regurgitation and neurohormonal changes. All of these lead to significant arrhythmias such as atrial fibrillation (AF) as well as ventricular arrhythmias, and are known risk factors for sudden cardiac ...
