Operations in the atrioventricular valves in the presence of blunt cardiac trauma (Figs. 30–32)
Road accidents, sporting injuries and injuries at work are steadily increasing in our mechanized civilization. As the patients usually suffer multiple traumas, a blunt cardiac trauma is frequently overlooked at first and eventually seals the fate of the patient. It is the most common visceral injury associated with a fatal outcome. Blunt thoracic injury should always raise the suspicion of damage to the ribs, sternum, thoracic viscera, or spinal column. Serial ECG and enzyme measurement have been the historic method of diagnosis. These should raise suspicion, but specificity is low, hence echocardiography, transthoracic or transesophageal, is the investigation of choice, providing us a real time window for assessing myocardial injury and function. Echocardiography is inexpensive, rapid, and the procedure can be performed safely at the bedside.
