Article Abstract
Implantable cardiac monitors have undergone considerable miniaturization. However, they continue to be associated with complications such as infection, bleeding/bruising, and device extrusion or migration. In this paper, we demonstrate the feasibility of using a small, flexible, injectable, subcutaneous microelectrode-based device to record electrocardiograms (ECGs). We describe the fabrication process and demonstrate the ease of insertion of the injectable ECG device in vivo swine model. We also demonstrate our device's high-density channel microelectrode array's ability to detect the P, R, and T waves. The amplitude of these waves showed excellent correlation with distance of the bipolar electrodes used to detect them. Given the success of our initial studies, this device has the potential to improve the safety profile of implantable cardiac monitors and simplify the implantation procedure to allow for placement in a primary care setting.

Limited vascularization and ischemia are major contributors to the chronicity of wounds, such as ulcers and traumatic injuries, which impose significant medical, social, and economic burdens. These challenges are particularly pronounced in patients with spinal cord injury (SCI), a disabling condition associated with vascular dysfunction, infections, and impaired peripheral circulation, complicating the treatment of pressure injuries (PIs) and the success of reconstructive procedures like grafts and flaps. Regenerative medicine aims to address these issues by identifying effective cellular therapies to restore vascular beds.

Background: Transcatheter pulmonary valve implantation (TPVI) has emerged as a viable alternative to surgical pulmonary valve replacement for patients with congenital heart disease and right ventricular outflow tract dysfunction. However, its adoption in low-resource settings has been limited.
Case Summary: We report the first successful TPVI procedures in Tanzania.
Improved Cardiac Structure and Ventricular-Arterial Coupling After Baroreflex Activation Therapy.

Cardiovascular Division, Department of Medicine, Froedtert and Medical College of Wisconsin, Milwaukee, Wisconsin, USA. Electronic address:
Baroreflex activation therapy (BAT) improves functional status, quality of life, and exercise capacity in patients with heart failure with reduced ejection fraction; however, its direct effects on reversing adverse cardiac remodeling as assessed by improvements in cardiac structure, function, and coupling with the arterial system remain unclear. We present 2 cases of patients who initially presented with decompensated heart failure, and despite initial medical therapy and continued outpatient follow-up, were unable to tolerate full escalation of guideline-directed medical therapy. The patients remained symptomatic, with high biomarker levels, poor functional capacity, severe heart failure symptoms, and objectively had decreased stroke volume, low left ventricular ejection fraction, and high left ventricular mass.

A middle-aged female presenting with progressive heart failure was admitted to the emergency department. She had a history of mitral and aortic valve replacement and a reoperation involving the Konno procedure. Echocardiography suggested a possible paraprosthetic leakage, which was confirmed during surgery.

The immediate results of PCI were assessed according to the TIMI scale; complications were assessed both clinically, by the incidence of severe complications (major adverse cardiovascular events, MACE), and angiographically, by the incidence of early and late ST and SR, and de novo stenosis that developed during the two-year observation period.
