Estimation of Prevalence of the Left Ventricular Noncompaction Among Adults.

The prevalence of left ventricular noncompacted myocardium (LVNC) is not clearly defined yet. The goal of this study was to prospectively assess the prevalence of LVNC in a population of patients assessed for cardiovascular disease and to analyze the coincidence between observers using the echocardiographic criteria for diagnosis of LVNC. We included patients prospectively during a 1-year period.

Lateral left ventricular wall rupture following acute myocardial infarction: pathophysiological interpretation by multimodality imaging approach.

Lateral left ventricular wall rupture (LVWR) is a rare complication following acute myocardial infarction (AMI) less than 1%. After cardiogenic shock, LVWR constitutes the most common cause of in-hospital death in AMI patients. Around 40% of all LVWR occurred during the first 24 hours and 85% within the first week.

Papillary muscle rupture associated to essential thrombocytosis.

Essential thrombocytosis (ET) falls under the umbrella of myeloproliferative disorders, which also includes chronic myelogenous leukemia, polycythemia vera, and myelofibrosis with myeloid metaplasia. Essential thrombocytosis results from a clonal proliferation of megakaryocites within the bone marrow, leading to an absolute elevation of platelets that can cause both hemorrhagic and thrombotic complications.

The short peritoneal equilibration test in pediatric peritoneal dialysis.

The peritoneal equilibration test (PET) is the gold standard method for defining peritoneal membrane permeability and for prescribing peritoneal dialysis (PD) therapy on an individual basis. However, it is laborious, consumes nursing time, and requires many hours to be performed. Therefore, several authors have attempted to validate a short PET protocol, with controversial results.
