Is there a right atrial appendage?

The right atrial appendage is generally the preferred location for the atrial lead. With the available retained guidewire, a new pacemaker introducer sheath is advanced over the wire into the SVC.

Where is the right atrial appendage located?

right atrium
The right atrial appendage forms a muscular pouch on the superoanterior aspect of the right atrium, overlapping the right side of the aortic root. This deep, trabeculated pocket facilitates quick, stable implantation [1].

Does everyone have a left atrial appendage?

The left atrial appendage (LAA) is a finger-like extension originating from the main body of the left atrium. Atrial fibrillation (AF) is the most common clinically important cardiac arrhythmia, occurring in approximately 0.4% to 1% of the general population and increasing with age to >8% in those >80 years of age.

What is right auricular appendage?

What is Koch’s triangle?

Koch’s triangle, named after the German pathologist and cardiologist Walter Karl Koch, is an anatomical area located in the superficial paraseptal endocardium of the right atrium, which its boundaries are the coronary sinus orifice, tendon of Todaro, and septal leaflet of the right atrioventricular valve.

Does everyone have an LAA?

The LAA is hollow, so it fills with blood when the left atrium receives blood and it empties when blood travels out of the left atrium. In most people the left atrial appendage is of little or no concern.

How common is left atrial enlargement?

A review of 15 studies over the last 12 years found that left atrial enlargement is present in 16 to 83 percent of people with either treated or untreated high blood pressure.
