Mechanical Aortic Valve Thromboembolism During Pregnancy on Low Molecular Weight Heparin.

A 31-year-old pregnant woman with a mechanical aortic valve developed a thrombus on her mechanical aortic valve due to subtherapeutic low molecular weight heparin dosage. She received intravenous heparin followed by warfarin. low molecular weight heparin dosing in pregnancy should be individualized, considering weight, physiological changes, and adjusted based on levels.

An Unusual Long-Term Complication of Bariatric Surgery.

Roux-en-Y gastric bypass (RNYGB) has become the standard of care in treating obesity, a global health concern with associated comorbidities contributing to rising health care costs [1]. The positive outcomes of RNYGB have been well documented along with adverse effects such as nutrient deficiencies, hernia, postprandial dumping syndrome, chronic kidney disease and hypoglycemia. A lesser-known long term complication of RNYGB is liver failure. Here, we present a case where RNYGB performed 10 years prior contributed to acute liver failure.

Venous Stent Migration of the Right Ventricle.

Peripheral migration of a venous stent to the heart is a rare but known complication, with the heart being the most common site of landing. Echocardiographic modalities are essential in clinical diagnosis and management, particularly with limited data and consensus regarding the best management approach.

Effects of medically generated electromagnetic interference from medical devices on cardiac implantable electronic devices: A review.

As cardiac implantable electronic devices (CIED) become more prevalent, it is important to acknowledge potential electromagnetic interference (EMI) from other sources, such as internal and external electronic devices and procedures and its effect on these devices. EMI from other sources can potentially inhibit pacing and trigger shocks in permanent pacemakers (PPM) and implantable cardioverter defibrillators (ICD), respectively. This review analyzes potential EMI amongst CIED and left ventricular assist device, deep brain stimulators, spinal cord stimulators, transcutaneous electrical nerve stimulators, and throughout an array of procedures, such as endoscopy, bronchoscopy, and procedures involving electrocautery. Although there is evidence to support EMI from internal and external devices and during procedures, there is a lack of large multicenter studies, and, as a result, current management guidelines are based primarily on expert opinion and anecdotal experience. We aim to provide a general overview of PPM/ICD function, review documented EMI effect on these devices, and acknowledge current management of CIED interference.
