Struma cordis, ectopic thyroid tissue located in the heart, is extremely rare. To our knowledge, this is the first report of struma cordis obstructing the left ventricular outflow tract. The tumor was removed successfully using cardiopulmonary bypass.

Resolution of a coronary artery thrombus within two weeks was demonstrated by serial coronary arteriography in a man with atherosclerotic coronary artery disease. This observation indicates that subtotal coronary artery thrombosis does not invariably progress to complete occlusion of the affected vessel and that the resolution of coronary artery thrombus can occur rapidly.
A patient with an anomalous intramyocardial course of the LAD coronary artery, causing angina pectoris, is described. The patient had symptomatic relief after an aortocoronary artery bypass operation. Intramural coronary arteries may be clinically significant. In cases where medical management does not provide relief, surgical correction of the anomaly may give symptomatic improvement and improved exercise tolerance.
Concentration of 99mTc-pyrophosphate (99mTc-PPi) in the area of left ventricular aneurysms is discussed. In three cases clinical, laboratory, and electrocardiographic (ECG) evidence did not indicate that these patients currently had an acute myocardial infarction, but each patient had a clinical history and an ECG picture compatible with an old myocardial infarction. Cardiac catheterization revealed a large left ventricular aneurysm in all three cases. The reason for the preferential uptake of the radionuclide in the area of these aneurysms is not certain at this time.
