OBJECTIVES Intraoperative transesophageal echocardiography (iTEE) has an important role in diagnosing the results of mitral valve (MV) replacement and repair. However, intraoperative Doppler features may be dissimilar from those measured at the postoperative follow-up period due to hemodynamic variations. There are no studies regarding MV surgery and comparisons between iTTE and postoperative transthoracic echocardiography (post-TTE). We aimed to evaluate the Doppler flow profiles observed in iTEE after MV replacement and repair and compare them with those observed in post-TTE. METHODS We conducted an observational study of 76 patients who underwent MV surgery (replacement or repair) over a 10-month period. iTEE was performed with Doppler evaluation (mean pressure gradient [MPG] and functional area). Patients were re-evaluated with TTE 72 hours after surgery (post-TTE). iTEE and post-TTE Doppler values were then compared and correlated. RESULTS The patients' mean age was 59 ± 18 years and 55% were women. The prevalence of severe mitral regurgitation and severe mitral stenosis was 77.6% and 22.4%, respectively. MV repair was performed in 71% of cases. iTEE Doppler parameters correlated with post-TTE parameters, with minimal differences, specially in the MV repair group. The postoperative MPG was +0.4 ± 1 mmHg higher in the MV repair group and +1.0 ± 1.8 mmHg in the MV replacement group. There was global improvement in terms of systolic pulmonary artery pressure, although left ventricular ejection fractions were slightly reduced during the postoperative evaluation. CONCLUSIONS Our study demonstrates the usefulness of iTEE and its importance in establishing possible reference values for postoperative follow-ups.
