Dynamic systolic compression of the coronary arteries is almost always due to the existence of myocardial bridging that is most commonly localized in the middle segment of the left anterior descending coronary artery. However, it has rarely been reported in patients with pericardial adhesions, tumor, foreign body, or pseudoaneurysms. Only rare case reports exist regarding dynamic coronary compression by a dyskinetic left ventricular aneurysm. We present a patient with a myocardial bridge-like systolic compression of the distal left anterior descending caused by postinfarction dyskinetic left ventricular aneurysm.

Hypothesis: Monodisperse phospholipid-coated microbubbles, with a size and resonance frequency tuned to the ultrasound driving frequency, have strong potential to enhance sensitivity, efficiency, and control in emerging diagnostic and therapeutic applications involving bubbles and ultrasound. A key requirement is that they retain their gas volume and shell material during physiologic pressure changes and withstand the overpressure during intravenous injection. The shell typically comprises a mixture of a phospholipid (e.

Posterior reversible encephalopathy syndrome (PRES) is a clinical manifestation of various underlying causes, characterized by the combination of clinical and imaging findings associated with the posterior cerebral areas and relating to arterial hypertension and endothelial dysfunction. No association was made so far between PRES and McCune-Albright syndrome (MAS), a rare genetic disorder resulting in fibrous dysplasia. A 33-year-old female with MAS was presented to the emergency department of the 417 Army Share Fund Hospital in Athens (Greece) after seizure activity with two episodes of ocular upward deviation and transient facial palsy, each lasting a few minutes, followed by a postictal phase.

Background: Pulmonary hypertension caused by extrinsic pulmonary vascular compression secondary to mediastinal neuroendocrine tumours is a very rare condition, posing a diagnostic challenge. There is no clear consensus regarding the best treatment strategy due to the lack of clinical data, leading to poor prognoses for these patients.
Case Summary: We present the case of a 38-year-old man hospitalized with signs of pulmonary hypertension and acute heart failure.

A young man presented with complaints of angina on exertion and dyspnoea on exertion for the last 3 months. On evaluation, he was found to have a cystic mass in the left ventricle with severe left ventricular systolic dysfunction. A cardiac MRI revealed a multiloculated mass in the left ventricle with multiple septa with internal enhancement and CT coronary angiography revealed compression of a coronary artery by the cystic mass.

Aims: 4D blood flow measurements by cardiac magnetic resonance imaging (CMR) can be used to simplify blood flow assessment. Compressed sensing (CS) can provide better flow measurements than conventional parallel imaging (PI), but clinical validation is needed. This study aimed to validate stroke volume (SV) measurements by 4D-CS in healthy volunteers and patients while also investigating the influence of the CS image reconstruction parameter on haemodynamic parameters.
