Without exposing patients to radiation, disease. Without exposing patients to radiation, echocardiograms provide detailed images that echocardiograms provide detailed images that can provide a wealth of helpful information — can provide a wealth of helpful information — including the size and shape of the heart, its including the size and shape of the heart, its pumping strength, and the location and extent of pumping strength, and the location and extent of any damage to its tissues. The new 3D any damage to its tissues. The new 3D technology can help doctors make better technology can help doctors make better diagnostic decisions because they can view the diagnostic decisions because they can view the data from any angle and see views not obtainable data from any angle and see views not obtainable from conventional two dimensional echo.from conventional two dimensional echo.

Using MRI, physicians can obtain images of the Using MRI, physicians can obtain images of the heart and blood vessels from different angles and heart and blood vessels from different angles and create moving images of the heart throughout its create moving images of the heart throughout its beating cycle. This allows for better assessment beating cycle. This allows for better assessment of complex cardiovascular anatomy compared to of complex cardiovascular anatomy compared to other imaging techniques. Cardiac MRI provides other imaging techniques. Cardiac MRI provides accurate assessment of ventricular function, accurate assessment of ventricular function, cardiac masses, valvular function, congenital cardiac masses, valvular function, congenital heart disease, coronary artery disease, heart disease, coronary artery disease, characterization of aorta and other blood vessels characterization of aorta and other blood vessels and is becoming recognized as the "gold and is becoming recognized as the "gold standard" for myocardial viability.standard" for myocardial viability.Cardiac MRI can help in the diagnosis and Cardiac MRI can help in the diagnosis and treatment of patients with following conditions:treatment of patients with following conditions: Coronary artery disease , Congestive heart Coronary artery disease , Congestive heart failure and cardiomyopathy, Congenital heart failure and cardiomyopathy, Congenital heart disease , Pericardial disease Cardiac masses and disease , Pericardial disease Cardiac masses and thrombi Arrhythmia , Aortic disease, Peripheral thrombi Arrhythmia , Aortic disease, Peripheral vascular disease, Valve diseasevascular disease, Valve disease

The Left main coronary artery or Left Main Trunk (LMT)The Left main coronary artery or Left Main Trunk (LMT) originates from the left coronary cusp and bifurcates to give rise to originates from the left coronary cusp and bifurcates to give rise to the Left anterior descending (LAD) and Left Circumflex (LCx) the Left anterior descending (LAD) and Left Circumflex (LCx) coronary arteries. Occasionally, a third branch vessel, the Ramus coronary arteries. Occasionally, a third branch vessel, the Ramus Intermedius (RI) arises from the LMT. Intermedius (RI) arises from the LMT.

The Left anterior descending coronary artery (LAD)The Left anterior descending coronary artery (LAD) provides provides blood supply to the anterior wall of the left ventricle. As it courses blood supply to the anterior wall of the left ventricle. As it courses through the anterior intraventricular groove it provides multiple through the anterior intraventricular groove it provides multiple septal branches to the interventricular septum and diagonal septal branches to the interventricular septum and diagonal branches to the anterior lateral wall. branches to the anterior lateral wall.

The Left Circumflex coronary artery (LCx)The Left Circumflex coronary artery (LCx) courses around the courses around the lateral or left atrio-ventricular groove and gives rise to multiple lateral or left atrio-ventricular groove and gives rise to multiple marginal or lateral branches. The branches are termed obtuse marginal or lateral branches. The branches are termed obtuse marginal (OM) or lateral branches depending on institutional marginal (OM) or lateral branches depending on institutional preference. preference.

The Right Coronary artery (RCA)The Right Coronary artery (RCA) arises from the right coronary arises from the right coronary cusp. This vessel follows the right AV groove and provides branches cusp. This vessel follows the right AV groove and provides branches to the right ventricle. The most proximal branches of the RCA are to the right ventricle. The most proximal branches of the RCA are the conus-branch which supplies the Right ventricular outflow tract the conus-branch which supplies the Right ventricular outflow tract and a branch that supplies the sino-atrial (SA) node (60% of and a branch that supplies the sino-atrial (SA) node (60% of patients). patients).

STRESS NUCLEAR PERFUSION STRESS NUCLEAR PERFUSION IMAGINGIMAGING

Also called a nuclear stress test, this Also called a nuclear stress test, this procedure is an imaging test that measures procedure is an imaging test that measures the extent of blood flow to the heart (i.e., the extent of blood flow to the heart (i.e., myocardial perfusion). myocardial perfusion). Doctor use this in conjunction with a Doctor use this in conjunction with a patient’s stress test, and it can be conducted patient’s stress test, and it can be conducted on a tread-mill, a stationary bicycle or by on a tread-mill, a stationary bicycle or by means of infusion of intravenous drugs to means of infusion of intravenous drugs to accelerate the heart rate. After the patient accelerate the heart rate. After the patient receives a small dose of radioactive tracer receives a small dose of radioactive tracer (thallium or technetium), physicians use a (thallium or technetium), physicians use a gamma camera to visualize the distribution gamma camera to visualize the distribution of blood in the myocardium.of blood in the myocardium.

PET permits assessment of myocardial assessment of myocardial perfusion and metabolism perfusion and metabolism with superior accuracy. The with superior accuracy. The results help physicians results help physicians identify the extent of heart identify the extent of heart disease and know when to disease and know when to suggest revascularization to suggest revascularization to the patient. CT helps to the patient. CT helps to further increase the accuracy further increase the accuracy of PET by allowing perfect of PET by allowing perfect alignment of the cardiac alignment of the cardiac silhouette and chest cage.silhouette and chest cage.
