OBJECTIVE

To study clinical and hemodynamic parameters of small-diameter aortic prostheses using stress echocardiography.

MATERIAL AND METHODS

The study included 89 patients who underwent aortic valve replacement with prostheses ≤21 mm. Mean age of patients was 48.7±10.2 (range 19.0—59.0) years. In long-term period (6.9±3.1 (range 1.9—12) years), all patients underwent a comprehensive examination including ECG, echocardiography and stress echocardiography.

RESULTS

Most patients have a significant decrease in transprosthetic pressure gradients and regression of myocardial hypertrophy in hospital and long-term period. According to stress echocardiography, maximum and mean pressure gradients were 52.0±9.0 (range 40.0—68.0) and 28.6±5.4 (range 25.0—43.0) mm Hg, respectively. These values significantly exceeded data of resting transthoracic echocardiography (23.2±5.0 (range 16.0—29.0) and 15.6±2.5 (range 13.0—18.0) mm Hg, respectively, p<0.05). Pulmonary artery pressure, stroke volume and left ventricular ejection fraction were normal. Signs of moderate prosthesis-patient mismatch were observed in 3 (15%) patients.

CONCLUSION

Stress echocardiography is an important method for hemodynamic assessment after aortic valve replacement with small-diameter prostheses. This method visualizes exercise-provoked prosthesis-patient mismatch and can be recommended in postoperative period, especially in young and middle-aged people.
