Abstract

Ventricular septal rupture (VSR) is an uncommon and devastating complication with a high mortality rate due to limited available interventions required by expert hands in a small window of opportunity. Most commonly seen following delayed myocardial infarctions (MI), the rate of VSR has decreased partly from protocol driven reperfusion therapy; however, cases are still present, particularly when diagnosis is delayed. We present a case of a critically ill patient in cardiogenic shock following a large anterolateral wall ST-elevation MI complicated by a large VSR whom was transferred to our academic institution for percutaneous repair. Of note, such intervention was initially performed by Lock in 1988 and a comprehensive review published in 2016 noted only 273 such cases. This review noted patient cases since that initial percutaneous closure by Lock with a majority of cases utilizing an Amplatzer system; others being Clamshell and CardioSEAL. Our patient underwent the percutaneous VSR closure utilizing an Amplatzer Occluder delivery system with successful insertion of an 18 mm muscular VSD Amplatzer closure device. Although the rarely performed procedure was successful and provided invaluable insights into the treatment and management of VSR, the patient succumbed to multiple critical disease processes in the following days post intervention. Patient consent and ethics committee approval for publication, as per Saint Louis University case publication guidelines, were confirmed and approved.

Abstract

Magnetite Co[Fe.sub.3][O.sub.4], a spinel structure (Fd3m), has interesting properties such as room-temperature ferrimagnetism, high Curie temperature, and spin polarization. The reasonable electrical conductivity of magnetite opens the possibility of modifying the saturation magnetization by inserting [Li.sup.+] ions into the structure, in a process similar to that used in conventional lithium batteries. In this study, we have measured the effects of electrochemical lithiation on the structure and magnetic properties of magnetite nanoparticles. A decrease in [M.sub.s] of up to 75% was observed upon addition of 2 moles of Li per formula unit, along with changes in remanence and coercivity. The insertion of [Li.sup.+] changes the moment by altering both the valence states and the locations of the Fe ions within the structure, and a model is proposed to explain the observations. Index Terms--Ferrimagnetic, magnetite, nanoparticles, spinel.
