Background .– 2D speckle imaging is a useful tool to evaluate right ventricular (RV) function at rest; however, the response of the RV to exercise has not been well established….
Background .– Previous care reports have suggested that dobutamine stress echocardiography may induce coronary artery spasm. The aim of this study was to assess the prevalence of coronary artery spasm…
Background .– The cardiac consequences of extensive athletic activity in men over the age of 50 years are unknown. Aims .– We intend to describe the remodelling that occur due…
After a positive stress echocardiography (stress echo), a coronary angiography is usually performed. When no significant lesion is found, the result is considered as a “false positive” test. Nevertheless, in…
We report a case of Takotsubo cardiomyopathy (TC) occurring after a transesophageal echocardiography (TOE). TC is a recently described syndrome characterized by transient left ventricular (LV) dysfunction, mimicking ST-segment elevation…
Purpose .– To analyse the relationship between changes in the transvalvular impedance signal (TVI) and echocardiographic markers of cardiac hemodynamics, during physical stress. Methods .– A semi-supine self-limited exercise echocardiography…
Purpose .– Right atrial (RA) strain (ε, %) analysis by two-dimensional speckle tracking (2DST) may represent a new tool to evaluate RA function. The aim of our study was to…
Background .– Because pulmonary hypertension (PH) seriously worsens prognosis of patients with EF < 35%, new drugs are currently being tested to improve hemodynamic and outcomes. The purpose of this…
Background and aim .– Assessment of right ventricular (RV) function is of prognostic value in patients undergoing cardiac surgery. In recent American guidelines, 2 definitions for the diagnosis of RV…
Objectives .– Pulmonary hypertension (PH) and right ventricular (RV) systolic dysfunction are two prognostic factors in advanced heart failure (AdHF). RV and pulmonary artery coupling is one of the main…
