Dobutamine stress echocardiography for noninvasive assessment and risk stratification of patients with rheumatic mitral stenosis

Abstract

In patients with MS, DSE is a safe and highly feasible stress test. A DSE-MG > or =18 mm Hg identifies a subgroup of high-risk patients in whom a more aggressive approach may be warranted; on the other hand, patients with a DSE-MG <18 mm Hg predicts an uneventful clinical course and may justify a more conservative strategy.

Role of the Mitral Valve Resistance in Evaluation of Mitral Stenosis Severity

“…We found that; MVR showed the best correlation with NYHA functional class when compared to the anatomical determinants of MS severity and it is an independent predictor of NYHA class, this explain the major role of MVR in development of dyspnia, thus, MVR could be a complement to the other conventional methods used in assessment of MS. Our results are in agreement with Izgi, et al [10] and others [17][18][19][20].…”

Echocardiographic Assessment of Degenerative Mitral Stenosis: A Diagnostic Challenge of an Emerging Cardiac Disease

“…78 Studies using Doppler echocardiography have also demonstrated that mean and peak TMPG and PA systolic pressure significantly increase with exercise in patients with MS. 79 Dobutamine stress echocardiography has also been confirmed as an effective and safe modality for assessment of severity of RMS. 80 Reis et al found that a TMPG cut-off value of ≥ 18 mmHg during exercise is a predictor of future adverse clinical events in patients with RMS. 80 Because exercise is more physiologic, it is the recommended way of stress for evaluation of MS. ) who claim to be asymptomatic with daily activities would develop dyspnea during a stress test.…”

Exercise Testing and Stress Imaging in Mitral Valve Disease

“…Reis et al [12] included 53 patients with moderate to severe MS and performed a DSE in all patients. After a mean follow-up of 60 months, 29 patients presented with cardiovascular complications.…”
