Cardiovascular magnetic resonance imaging and clinical performance of somatostatin receptor positron emission tomography in cardiac sarcoidosis: CMR and SSTR PET in cardiac sarcoidosis

Cardiac affection constitutes a major limiting condition in systemic sarcoidosis. The primary objective of this study was to investigate the persistence rate of cardiac sarcoid involvement by cardiovascular magnetic resonance (CMR) imaging in patients diagnosed with cardiac sarcoidosis (CS). Moreover, we examined the additional insights into myocardial damages characteristics gained by somatostatin receptor scintigraphy.

Nitinol stent insertion in tracheomalacia

A 69-year-old man was admitted to our hospital with progressive dyspnoea accompanied by inspiratory stridor. He presented a history of surgical aortic valve replacement 3 years previously, complicated by prolonged postoperative mechanical ventilation requiring percutaneous tracheostomy. Presently, bronchoscopy evidenced tracheomalacia (TM) with subtotal tracheal stenosis. CT scan confirmed long segment narrowing >20 mm of the upper trachea (figure 1). Operative retracheostomy resulted in repeated tube dislocation …

Epicardial adipose tissue, aortic stiffness and myocardial fibrosis in healthy individuals: a quantitative cardiac magnetic resonance study

Background Epicardial adipose tissue, aortic stiffness and myocardial fibrosis have been linked to cardiovascular risk and disease; however, often different modalities are used for their measurement. Cardiac magnetic resonance (CMR) may be used to determine these parameters in a single examination by the measurement of epicardial fat volumes (EFV), aortic pulse wave velocity (PWV) as a parameter of aortic stiffness, and T1-relaxation time (T1) as a marker for myocardial fibrosis. This quantitative CMR-study was performed to identify relationships between these parameters in healthy individuals and to correlate them with age, body mass index (BMI) and gender.
