Hypertrabeculation is a feature of the left ventricle that, by itself, does not coincide with left ventricular non compaction (LVNC), which represents a specific cardiomyopathy. Nowadays, in the absence of gold standard diagnostic criteria, the clinician must integrate imaging aspects together with medical history. The family inheritance for LVNC, presence of neuromuscular disorders, symptoms or signs of heart failure, thromboembolic events, unexplained syncope, pathological findings at rest ECG, Holter ECG, stress test, systolic/diastolic dysfunction at rest echocardiogram, late gadolinium enhancement at cardiac magnetic resonance, and identification of specific mutations are all considered features useful for the diagnosis...

Mental state monitoring is a critical component of current and future human-machine interfaces, including semi-autonomous driving and flying, air traffic control, decision aids, training systems, and will soon be integrated into ubiquitous products like cell phones and laptops. Current mental state assessment approaches supply quantitative measures, but their only frame of reference is generic population-level ranges. What is needed are physiological biometrics that are validated in the context of task performance of individuals...

BACKGROUND: Several characteristics of the ventricular fibrillation (VF) waveform during cardiac arrest are associated with defibrillation success, including peak amplitude in the seconds prior to defibrillation. It is not known if immediate pre-defibrillation amplitude is associated with successful defibrillation, return of spontaneous circulation (ROSC) or survival to hospital discharge (SHD). METHODS: We analyzed automated external defibrillation recordings of 80 patients with out-of-hospital VF cardiac arrest who received 284 defibrillations...

Incorrect prosthesis size has direct impact on patient outcome after transcatheter aortic valve implantation (TAVI) procedure. Currently, annular diameter, area or perimeter may be used for prosthesis size selection. The aim was to evaluate whether the use different annular dimensions would result in the selection of different prosthesis sizes, when assessed in the same TAVI-candidate during the same phase of a cardiac cycle. Fifty consecutive TAVI-candidates underwent retrospectively ECG-gated computed tomography angiography (CTA)...

We report a 57-year-old man presenting with symptoms of sharp pricking, exertional retrosternal chest pain multiple times, each episode lasting for a few seconds. On evaluation, the ECG of the patient showed normal sinus rhythm with T wave inversions in leads V1-V3. Troponin T test was negative. Transthoracic echocardiography showed a globular mass in the interventricular septum. Cardiac MRI was suspicious of the lesion to be a hydatid cyst. Surgical excision of the lesion followed by histopathology was confirmatory of hydatid cyst...

Aging in humans represents declining in cardio-protective systems, however its mechanisms are not known yet. We aimed to analyse how aging affects key mechanisms responsible for contractile dysfunction via comparing the improperly synchrony between electrical and mechanical activities in male aged-rats (24-month old) comparison to those of adult-rats (6-month old). We determined significantly increased systemic oxidative stress with decreased antioxidant capacity, clear insulin resistance and hypertrophy in aged-rats with normal fasting blood glucose...
