In two patients with a symptomatic posteroseptally localized accessory atrioventricular pathway, but with distinct electrocardiographic patterns, a coronary sinus diverticulum appeared to be the site of this connection. Radiofrequency catheter ablation in the diverticulum was implemented to interrupt the pathway in both cases. This study demonstrates the necessity to perform coronary sinus angiography when ablation attempts in the posteroseptal region are not immediately successful, or optimal signals are not detected.

D004240 Diverticulum A pouch or sac developed from a tubular or saccular organ, such as the GASTROINTESTINAL TRACT. Diverticulosis,Diverticula
D004562 Electrocardiography Recording of the moment-to-moment electromotive forces of the HEART as projected onto various sites on the body's surface, delineated as a scalar function of time. The recording is monitored by a tracing on slow moving chart paper or by observing it on a cardioscope, which is a CATHODE RAY TUBE DISPLAY. 12-Lead ECG,12-Lead EKG,12-Lead Electrocardiography,Cardiography,ECG,EKG,Electrocardiogram,Electrocardiograph,12 Lead ECG,12 Lead EKG,12 Lead Electrocardiography,12-Lead ECGs,12-Lead EKGs,12-Lead Electrocardiographies,Cardiographies,ECG, 12-Lead,EKG, 12-Lead,Electrocardiograms,Electrocardiographies, 12-Lead,Electrocardiographs,Electrocardiography, 12-Lead
D006329 Heart Conduction System An impulse-conducting system composed of modified cardiac muscle, having the power of spontaneous rhythmicity and conduction more highly developed than the rest of the heart.

D000328 Adult A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available. Adults
D013617 Tachycardia, Supraventricular A generic expression for any tachycardia that originates above the BUNDLE OF HIS. Supraventricular Tachycardia,Supraventricular Tachycardias,Tachycardias, Supraventricular
D014927 Wolff-Parkinson-White Syndrome A form of ventricular pre-excitation characterized by a short PR interval and a long QRS interval with a delta wave. In this syndrome, atrial impulses are abnormally conducted to the HEART VENTRICLES via an ACCESSORY CONDUCTING PATHWAY that is located between the wall of the right or left atria and the ventricles, also known as a BUNDLE OF KENT. The inherited form can be caused by mutation of PRKAG2 gene encoding a gamma-2 regulatory subunit of AMP-activated protein kinase.

D017023 Coronary Angiography Radiography of the vascular system of the heart muscle after injection of a contrast medium. Angiography, Coronary,Angiographies, Coronary,Coronary Angiographies
