Echocardiography in the Era of Multimodality Cardiovascular Imaging
Figure 2
A patient with moderate mitral stenosis but worsening exertional dyspnoea underwent exercise SE. At rest, mean transmitral gradient was 5 mm Hg (a), and transtricuspid pressure gradient was 24 mm Hg (b). After 7-minute BRUCE protocol treadmill exercise, mean transmitral gradient significantly increased to 27 mm Hg (c) and transtricuspid pressure gradient had more than doubled to 51 mm Hg (d). The patient subsequently underwent balloon mitral valvuloplasty with excellent symptomatic relief.
