A new perspective on aortic pressure for transcatheter closure of patent ductus arteriosus in the pediatric population.

Background: Hemodynamic assessment is not routinely performed when closing a patent ductus arteriosus (PDA). Significant PDA flow causes a drop in the aortic pressure distal to the shunt. Closure of PDA should increase distal systemic blood flow and significantly elevate distal aortic pressure, changing the systolic pressure gradient (ΔP) between the proximal and distal aorta.

Case Report: Heart aneurysm of unknown origin in a two-year-old child diagnosed in the course of Multisystem Inflammatory Syndrome in Children.

We present a case of a 22-month-old boy with a hypokinetic and thin-walled aneurysm of the left ventricle apex. The lesion was diagnosed during routine echocardiography examination in the course of MIS-C, and its occurrence due to MIS-C is plausible. Cardiac magnetic resonance imaging revealed an akinetic aneurysm of the LV apex with a full-wall ischemic scar.

Wolfram Syndrome. Case report.

Wolfram syndrome is a rare neurodegenerative and genetic disorder, characterized by insulin-dependent diabetes mellitus, caused by non-autoimmune loss of β cells, as well as optic atrophy; the disease is also known as DIDMOAD (diabetes insipidus, diabetes mellitus, optic atrophy, and deafness). Patients that demonstrate diabetes mellitus are also affected by: optic atrophy in the first decade of their life, diabetes insipidus and sensorineural deafness in the second decade, and urinary tract and neurological abnormalities in the third decade of their life. Patients with Wolfram syndrome usually die due to central respiratory failures caused by brain stem atrophy in their third or at the beginning of their fourth decade of life.
