| heart block | interference with the electrical conduction of the heart |
| mitral | AV valve; left atrioventricular valve; bicuspid; shaped like a miter |
| angiorrhaphy | suture of a vessel |
| stroke volume | blood volume pumped by the heart with each contraction |

| mediastinum | structures in the chest between the two lungs including lungs, large blood vessels, esophagus, trachea, lymph nodes, and trachea |
| insufficiency | leakage due to inability of the valve to perform at the proper level |
