The role of echocardiography in the diagnosis of valvular disease
Echocardiography can clear the cardiac cavity size, blood flow velocity, the valve opening area, opening and closing conditions and valvular calcification, vegetation and so on, especially for valvular regurgitation is very sensitive. Echocardiography can clear how much the amount of pericardial effusion and in cardiac surgery and to determine the quality of artificial valve, activity after valve surgery, there is no card flap phenomenon has good identification effect, can be used in intraoperative transesophageal echocardiography technique to determine the effect of the operation, how to clear the valve leakage and the annuloplasty effect, if there is a problem, can further correct treatment of reoperation. So echocardiography is the main diagnostic method of valve surgery. Moreover, this method is non-invasive and can be repeated.
The role of chest radiography in the diagnosis of valvular disease
Chest X-ray can not only observe the size of the heart, also can clear the number and thickness of lung markings, to which the heart cavity changes, but also understand the pulmonary circulation situation, there is no obvious aortic calcification, in order to evaluate the extent of the disease. Postoperative chest X-ray examination can be used to determine the presence of non aspiration fluid, lung, and preoperative and postoperative cardiac changes. The image of heart valve disease often increases, such as esophageal barium meal examination found that esophageal compression, left atrial enlargement, a large amount of pericardial effusion, cardiac imaging has changed shape flask.
The role of electrocardiogram in the diagnosis of valvular disease
ECG is the most commonly used means of cardiac surgery, you can understand the patient's heart rate and rhythm changes, for a variety of arrhythmia, can be based on changes in the ECG drug, and observe the effect of medication. Can also be based on changes in the understanding of the extent of the disease and its progress, can also be used to evaluate the effect of cardiac surgery.
The role of coronary angiography in the diagnosis of valvular disease
For patients over the age of 50 years or with symptoms of coronary artery stenosis, coronary angiography was performed routinely before surgery, and the results of coronary artery bypass grafting (CABG) were determined according to the results. Because, after 50 years of age is a high incidence of coronary heart disease. If the combination of severe coronary artery stenosis without coronary artery bypass surgery, myocardial ischemia and surgical intervention, the heart may not be able to jump after surgery, or low cardiac output syndrome, it is difficult to correct.
