Is T-Wave Alternans a Repolarization Abnormality Marker in COVID-19? An Investigation on the Potentialities of Portable Electrocardiogram Device.

Background: Cardiac arrhythmias are significantly associated with poor outcomes in coronavirus disease 2019 (COVID-19) patients. Microvolt T-wave alternans (TWA) can be automatically quantified and has been recognized as a representation of repolarization heterogeneity and linked to arrhythmogenesis in various cardiovascular diseases. This study aimed to explore the correlation between microvolt TWA and COVID-19 pathology.

COVID arm as a common cutaneous manifestation after mRNA-1273 vaccination: a systematic review.

Background: By August 2022, CoronaVirus Disease-2019 (COVID-19) had caused 600 million illnesses and 6.5 million fatalities globally. A massive vaccination program is being implemented worldwide to suppress this condition.

Small residual patent ductus arteriosus after surgical ligation in young adult: to close or not to close - a dilemmatic case report.

Percutaneous transcatheter closure has gained acceptance for patent ductus arteriosus (PDA) management ever since its introduction, including the management residual left-to-right shunts following surgical ligations. It is preferred than the more invasive surgical closure. While large PDA is closed to prevent heart failure, the decision to close a small hemodynamically insignificant PDA is still a debatable issue.

Arrhythmia Risk Profile and Ventricular Repolarization Indices in COVID-19 Patients: A Systematic Review and Meta-Analysis.

Introduction: Coronavirus disease 2019 (COVID-19) has been associated with cardiac arrhythmias. Several electrocardiographic markers have been used to predict the risk of arrhythmia in patients with COVID-19. We aim to investigate the electrocardiographic (ECG) ventricular repolarization indices in patients with COVID-19.

A Systematic Review of Jailed Balloon Technique for Coronary Bifurcation Lesion: Conventional-Jailed Balloon Technique vs Modified-Jailed Balloon Technique.

Background: In this systematic review, we aim to evaluate the latest evidence on the efficacy and safety of conventional jailed balloon technique and modified jailed balloon technique for bifurcation lesion, and also whether the former or latter is more effective for preventing side branch occlusion during main branch stenting in bifurcation lesions.

Methods: We performed comprehensive search on studies assessing the efficacy and safety of conventional jailed balloon and modified jailed balloon technique for bifurcation lesion from several electronic databases.

Results: There were 908 patients from six studies comprising of 615 in conventional jailed balloon technique group and 293 in modified jailed balloon technique group.

Transjugular Seldinger approach for permanent pacemaker implantation in octogenarian with inaccessible upper limbs venous system.

In up to 13.7% of device implants, lead entry through the cephalic, axillary, or subclavian veins might be unfeasible. Transjugular permanent pacemaker (PPM) implantation may be considered as a bailout strategy in the difficult anatomy of conventional veins, before resorting to epicardial pacing lead, which requires general anesthesia and thoracotomy.
