Abstract
Between February 1986 and June 1987,306 consecutive patients were included in a programme of non-invasive preoperative assessment of valvular heart disease using M-mode and cross-sectional echocardiography and Doppler ultrasound. In 285 cases (93%), echocardiography provided all the necessary preoperative information. Coronary angiography was performed in 74 patients because of angina and in 55 because of their age. Invasive investigation was needed in 21 cases because of discrepancies between clinical data and echo-Doppler results. The results were definitely misleading in six patients, mainly due to erroneous assessment of valvular regurgitation. One hundred and ninety one patients underwent valve surgery (179 evaluated exclusively by echocardiography, 79 with coronary angiography as the sole invasive procedure). No discrepancies were observed between echo-Doppler diagnosis and macroscopic evaluation of valvular heart disease at surgery. Operative mortality (3.6%) was not significantly different from that observed during the preceeding period when preoperative catheterisation was performed (3.3%). It is concluded that echo-Doppler techniques are perfectly satisfactory for the preoperative assessment of patients with valvular heart disease. Cardiac catheterisation is only infrequently required, although coronary angiography remains mandatory in a selected group of these patients.
