An interatrial mass supplied from dual coronary circulation
Abstract:
A 69-year-old woman has been complaining from presencop and palpitation for 4 months. Cardiac examination revealed middiastolic rulman, which changed by position. Transthoracic and transesophageal echocardiography showed normal left ventricular function, mild mitral regurgitation and large right and left atrial masses. This mass prolapsed through the mitral valve into the left ventricle during diastole and caused dynamic obstruction. Coronary angiography revealed that the masses were supplied via left and right coronary artery without any significant stenosis of the coronary arteries. Prediagnosed, however, as multiple myxomas, the results of the pathology indicated a completely different origin.

Coronary Circulation
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...

Physiology of the Heart: The Cardiac Cycle
Diastole: The Relaxation Phase
During diastole, all four heart chambers relax. The atrioventricular (AV) valves open, and the semilunar valves close. This phase sees the lowest chamber pressures, promoting ventricular filling. Venous blood enters the heart through the...

Anatomy of the Heart
The heart has three layers: the innermost endocardium, the muscular myocardium, and the outer epicardium, all working together for optimal cardiac function.

The Cardiac Cycle
The Process
Electrical signals—sent from the sinoatrial (SA) node in the right atrial wall to the atrioventricular (AV) node between the right atrium and right ventricle—cause both atria to simultaneously contract. When the signal reaches the AV node, it pauses for approximately a tenth of a second, allowing the atria to contract and empty blood into the...
