Massive perinatal left ventricle infarction treated with tissue plasminogen activator: No ECMO - A case report.

Neonatal myocardial infarction due to coronary thrombus is a rare cause of acute heart failure and is associated with high morbidity and mortality. We present a rare case of a full-term newborn who developed coronary artery thrombus treated with intracoronary recombinant tissue plasminogen activator infusion while undergoing therapeutic hypothermia. Also, we describe a unique treatment strategy to support systemic circulation sparing the patient from neonatal extracorporeal membrane oxygenation and its complications.

Infantile Scimitar Syndrome With Contralateral Pulmonary Vein Stenosis and Refractory Pulmonary Hypertension.

Infantile scimitar syndrome is associated with pulmonary hypertension which can be difficult to manage. We present a three-month-old infant with scimitar syndrome, who eventually developed refractory pulmonary hypertension, posing a significant management challenge. Further workup demonstrated contralateral pulmonary vein stenosis, which is rarely described in scimitar syndrome.

Echocardiographic Findings in Children with Native Mitral Valve Masses Complicated by Systemic Embolization.

• Case of mitral valve IMT with embolization. • Case of mitral valve endocarditis with embolization. • Use of 2D and 3D echocardiography for management of mitral valve masses.

Mechanism of Action of Veverimer: A Novel, Orally Administered, Nonabsorbed, Counterion-Free, Hydrochloric Acid Binder under Development for the Treatment of Metabolic Acidosis in Chronic Kidney Disease.

Current management of metabolic acidosis in patients with chronic kidney disease (CKD) relies on dietary intervention to reduce daily endogenous acid production or neutralization of retained acid with oral alkali (sodium bicarbonate, sodium citrate). Veverimer is being developed as a novel oral treatment for metabolic acidosis through removal of intestinal acid, resulting in an increase in serum bicarbonate. Veverimer is a free-amine polymer that combines high capacity and selectivity to bind and remove hydrochloric acid (HCl) from the gastrointestinal (GI) tract.

Mechanisms of Metabolic Acidosis-Induced Kidney Injury in Chronic Kidney Disease.

Retrospective analyses and single-center prospective studies identify chronic metabolic acidosis as an independent and modifiable risk factor for progression of CKD. In patients with CKD, untreated chronic metabolic acidosis often leads to an accelerated reduction in GFR. Mechanisms responsible for this reduction include adaptive responses that increase acid excretion but lead to a decline in kidney function.
