Rare Manifestation of COVID-19 Resulting in Coronary Artery Vasculitis.

We present the case of a 59-year-old African American female with end-stage renal disease (ESRD) who presented to the emergency department with chest discomfort. She had a coronary angiogram six months ago that showed no occlusive epicardial coronary artery disease. She had elevated troponin I levels and new regional wall motion abnormalities on echocardiogram.

Iatrogenic Left Ventricle Outflow Tract Ventricular Tachycardia Following Transcatheter Aortic Valve Replacement: A Case Series.

Focal left ventricular outflow tract ventricular tachycardia (LVOT-VT) is rarely reported following transcatheter aortic valve replacement (TAVR). Similarly, unexplained sudden cardiac death after TAVR also is rarely described and may be attributed to VT. We present two cases of patients who underwent TAVR and later presented with VT of suggested LVOT origin.

Optimal antiplatelet and antithrombotic regimen post-transcatheter aortic valve replacement.

Background: There are limited data regarding optimal antiplatelet/antithrombotic therapy following transcatheter aortic valve replacement (TAVR).

Methods: In this single-centre retrospective study including TAVR patients from 2012 to 2020, ischemic and bleeding outcomes were compared between antiplatelet (dual antiplatelet [DAPT] vs. single antiplatelet [SAPT]) and oral anticoagulation (OAC) groups using incidence rate, Kaplan-Meier and Cox proportional hazards analysis.

Reassessing hepatocellular carcinoma staging in a changing patient population.

Objective: Hepatocellular carcinoma (HCC) staging systems were developed using data predominantly from patients who had hepatitis and cirrhosis. Given the recent change in prevalence of viral hepatitis and cirrhosis at oncology centers, which has altered the natural history of HCC, we aimed at comparing the accuracy of HCC staging systems in patients with or without hepatitis and cirrhosis.

Methods: A total of 438 patients were enrolled.
