Reading and interpreting the graphs In this section I will guide the reader through the interpretation of the different strain/ SR graphs. All relevant definitions are found at the beginning of this document. For the sake of simplicity I present only a single graph in the figures instead of the 6 different regional and additional […]

“How-to”: Image acquisition Several key steps need to be undertaken for optimal derivation/calculation of regional and global deformation. I would like to redirect the reader to earlier published work by our group (open access paper, click link) where we describe our applied methods for the optimal image acquisition. This manuscript also guides the reader through […]
Definitions Displacement (mm) Amount of distance which a predefined region of the heart moves during a predefined time interval. Typically, the displacement of the annular plane (either the mitral or the tricuspid) during systole in the longitudinal direction (towards the transducer). Value is expressed in mm or cm. Velocity (cm/sec) The (maximum) speed of […]
Case The following case represents a 20 year old male with a known high cervical transverse lesion after an accident which left him wheelchair bound. He presented with a pneumonia which was complicated with a purulent pleuritis and a purulent pericarditis. He was treated with broad spectrum antibiotics. The pericardial exudate (empyema) was not evacuated […]
Case 1 Patient with myocarditis. Severe global LV dysfunction in combination with troponin release following a clinical episode of upper tract respiratory infection. Conventional ultrasound LVEF of 20% due to global LV hypokinesia. See images below Deformation imaging Deformation imaging showed marked regional abnormalities with clear reduction of peak systolic strain in […]
In this case, strain features of an acute inferior myocardial infarction caused by a RCA occlusion are presented. Case A 53 year old man was brought to the emergency department because of persisting symptoms of angina pectoris accompanied by perspiration and dyspnea in rest. Initial ECG showed ST elevation in the inferior wall and reciprocal […]
Case: acute anterior myocardial infarction The following case presents the characteristics on speckle strain imaging of acute anterior myocardial infarction caused by occlusion of the LAD. We present the acute findings directly after an emergency PCI and the long term follow up findings in this specific case (with transmural myocardial infarction) A 44 year […]
Case: 55-year old male who was known for several years with asymptomatic concentric left ventricular hypertrophy. This condition was also known in his family, although no genetic testing was performed. He developed complaints of heart failure (NYHA functional class III/IV) for which he was admitted. The ECG showed a decrease in QRS voltage compared to […]
Case: 55-year old man was referred to our outpatient clinic for the endocrinology department. He is known with a neuro-endocrine tumor (NET) in his small intestine with known liver and lymph node metastases. He is currently treated with octreotide. A routine follow up PET-scan showed a “hot-spot” in the LV myocardium (scan shown below). He […]
Case: 50 year old man known at our institution since 2012. He initially presented with an out of hospital cardiac arrest based on ventricular fibrillation. Coronary angiography was completely normal and ultrasound showed a normal LV function with hypokinesia in the inferior wall. CMR at the time of presentation showed a focal epicardial spot of […]
