Measuring the Quality of Care Given to Heart Surgery Patients at Cedars-Sinai

The ability to replace blocked or narrowed arteries or poorly working valves in the heart has been an enormous advancement in the treatment of heart disease.

According to the American Heart Association, coronary artery bypass surgeries made up nearly 65% of all open heart surgeries done in 2006. Valve replacement surgeries made up nearly 15%.

The tables below compare the number of surgeries and mortality rates at Cedars-Sinai with those of three other medical centers.

Isolated Coronary Artery Bypass Graft (CABG) Surgery

Coronary artery bypass surgery uses arteries or veins from one part of a patient¿s body to create a bypass around blocked or narrowed arteries in the heart. This increases the flow of blood to the heart muscle. Having this procedure helps reduce chest pain (angina) and reduces the risk of death from coronary artery disease.

Isolated coronary artery bypass surgery is when no other heart procedure is done at the same time as the bypass surgery.

The table below shows how Cedars-Sinai compares to three other California medical centers in terms of the number of coronary artery bypass surgeries done and the mortality rate for the procedure.

Aortic Valve Replacement Surgery

The aortic valve separates the left ventricle from the aortic artery. When it opens, the heart pumps oxygen-enriched blood through the body. A variety of diseases or birth defects can cause the aortic valve to either not close properly or not fully open when the heart beats.

The table below shows how Cedars-Sinai compares to three other California medical centers in terms of the number of aortic valve replacement surgeries done and the mortality rate for the procedure.

Mitral Valve Replacement Surgery

The mitral valve separates the left atrium from the left ventricle. When the mitral valve is closed, the left atrium fills with oxygen-enriched blood. When the mitral valve opens, that blood is pumped into the left ventricle. The left ventricle is the strongest chamber of the heart, when it pumps blood is sent through the aortic valve into the body.

The table below shows how Cedars-Sinai compares to three other California medical centers in terms of the number of mitral valve replacement surgeries done and the mortality rate for the procedure.
