Octopus Papillary Muscle Associated with a Left Lateral Accessory Pathway

CONGENITAL HEART DISEASE, Issue 6 2009
Manisha S. Patel MD
ABSTRACT Left ventricular papillary muscle abnormalities are rare malformations. They have been related to significant mitral valve dysfunction and left ventricular midcavitary obstruction. We report our experience with a young adult who presented with palpitations. An echocardiogram on the patient showed an "octopus-like" left ventricular papillary muscle. Subsequent electrophysiologic testing showed evidence of supraventricular tachycardia via a left lateral accessory pathway associated with the abnormal insertion of the papillary muscle attachments.

Coexisting Idiopathic Left Ventricular Tachycardia and Atrioventricular Reentrant Tachycardia in a Patient with Wolff-Parkinson-White Syndrome

PACING AND CLINICAL ELECTROPHYSIOLOGY, Issue 2 2009
HONG EUY LIM M.D., Ph.D.
We report a patient with Wolff-Parkinson-White syndrome who presented with two distinct tachycardias that represented atrioventricular reentrant tachycardia utilizing left lateral accessory pathway (AP) and idiopathic left ventricular tachycardia (ILVT). Two tachycardias with a complete separate mechanism occurred spontaneously as well as following atrial or ventricular pacing. Successful ablation of the left AP and ILVT resulted in a cure of the double tachycardia. [source]

Precipitation of Ventricular Fibrillation by Intravenous Diltiazem and Metoprolol in a Young Patient with Occult Wolff-Parkinson-White Syndrome

PACING AND CLINICAL ELECTROPHYSIOLOGY, Issue 6 2008
ROBERT J. KIM M.D.
We report the case of a young man who presented with a rapid, narrow-complex atrial fibrillation. A few hours after being administered intravenous metoprolol and diltiazem for rate control, he developed intermittent ventricular preexcitation on the electrocardiogram (ECG) and experienced ventricular fibrillation, from which he was successfully defibrillated. A subsequent electrocardiogram in sinus rhythm demonstrated previously unknown Wolff-Parkinson-White pattern. A left lateral accessory pathway was successfully ablated. Wolff-Parkinson-White syndrome should be included in the differential diagnosis when a young patient presents with atrial fibrillation, even if the ventricular complexes on the ECG are not preexcited.
