“…The full-length of exercise imaging as mentioned before may have contributed to the high number of patients that developed SAM of the mitral valve in association with IVG, compared to other authors’ data [57,58] (Additional file 1 and 2) [7]. It could have also contributed to the increased magnitude of the IVG.…”

“…The results of our study, in which 36% of the patients with normal coronary angiogram and positive treadmill exercise test developed significant intra-ventricular gradients, suggest that ST-segment depression may be related with the development of IVG during exercise, which is possibly involved in the genesis of electrocardiographic changes. The possible association between cardiac X syndrome and IVG during exercise was described before [57,58], however the inclusion of patients more prone to develop IVG such as hypertensive ones with left ventricular hypertrophy limits their findings [41]. …”

Exercise stress echocardiography is the most frequently used stress test in our laboratory. Exercise echocardiography is used mainly in the study of patients with coronary artery disease. However, the technique is increasingly being used to study other diseases.In our centre, we use an original methodology, published by us in 2000, in which we evaluate heart function during exercise in the treadmill. After the exercise, patients are maintained in orthostatic position when appropriate or lying down in left lateral decubitus for further evaluation. Since this method seems to increase the quality and the quantity of information obtained in so many clinical arenas, we now present a detailed review of this methodology and its applications.

“…3 In this context, IVG is more frequently described in athletes or in situations with increased inotropic stimuli as during dobutamine stress echocardiogram. 6,7 Exercise stress echocardiogram plays a relevant role in the evaluation of symptomatic athletes, with reproduction of symptoms and the potential detection of significant IVGs. 1,8 …”

“…The main sign of intraventricular dynamic obstruction is present in most cases, and when SAM occurs ( Figure 1 ), the configuration of the ventricular cavity or of the mitral valve apparatus is altered. Notably, a significant number of patients with intraventricular gradients [ 15 , 17 ] have mid-ventricular (MV) obstruction without SAM.…”

This review aims to serve as a guide for clinical practice and to appraise the current knowledge on exercise stress echocardiography in the evaluation of intraventricular obstruction in HCM, in patients with cardiac syndrome X, in athletes with symptoms related to exercise, and in patients with normal left ventricular systolic function and exercise-related unexplained tiredness. The appearance of intraventricular obstruction while exercising is considered rare, and it usually occurs in patients with hypertrophy of the left ventricle. The occurrence of intraventricular obstruction when exercising has been evidenced in patients with hypertrophic cardiomyopathy, athletes, patients with cardiac syndrome X, patients with syncope or dizziness related to exercise, and patients with dyspnea and preserved ejection fraction. The clinical significance of this observation and the exercise modality that is most likely to trigger intraventricular obstruction remains unknown. Supine exercise and lying supine after exercise are less technically demanding, but they are also less physiologically demanding than upright exercise. Importantly, in everyday life, human beings generally do not become supine after exercise, as takes place in post-exercise treadmill stress echocardiograms in most echocardiography labs. The presence of induced intraventricular obstruction might be considered when patients have exercise-related symptoms that are not understood, and to assess prognosis in hypertrophic cardiomyopathy.
