Abstract
Background
Patients undergoing mitral valve surgery were assessed for morphology and function by Transoesophageal Echocardiography (TEE) at surgery over a 5 year period.
Methods
From January 1994 through May 1998, 591 patients underwent mitral valve surgery. Four hundred and eleven patients (mean age 22+3.6 yrs, range 8 years to 55 years, 186 male) underwent mitral valve reconstruction, 143 patients (mean age 24.5+4.2 yrs. (range 10–55 years, 67 male) underwent Open Mitral commissurotomy (OMC), and 37 patients (mean age 26.5 + 4.7 yrs., range 10–49 yrs, 25 male) underwent. Homgraft Mitral Valve Replacement (HMVR). Assessment of mitral valve was performed in the four chamber view. Doppler color flow mapping provided assessment of severity of Mitral Regurgitation (MR) and tricuspid regurgitation.
Results
The preoperative assessment was predictive for reparability in 405 patients with MR. All of these patients had a satisfactory repair. In six additional patients the post bypass Intraoperative Transoesophageal Echocardiography (ITTE) demonstrated moderate to severe MR and therefore the repair was considered unsatisfactory. The valve was replaced by a prosthesis in these cases in the same session. Mild MR was diagnosed in 38 cases on post repair TEE and was not corrected. All other patients had a satisfactory repair. Gross thickening of the leaflet (6 mm or more) at the base, calcification and central anterior leaflet tear were considered unsuitable for repair.
Conclusion
In conclusion ITEE is easy to learn, the equipment and software are user friendly and the examination can be performed within a short period.
