Successful Transfemoral Transcatheter Aortic Valve Replacement in a Patient with Double Aortic Arch: An Interesting Imaging Case.

Transcatheter aortic valve replacement (TAVR) has become a mainstay of treatment in the management of severe aortic stenosis. It is a challenging procedure that requires expertise in obtaining proper access, delivery of catheters to and beyond the aortic valve, and finally accurate deployment of the aortic bioprosthesis. Patients with aortic anomalies portend an added challenge in performing TAVR procedures. We present the case of a patient incidentally found to have a right dominant double aortic arch who underwent successful TAVR for severe aortic stenosis.

COVID-19 cardiovascular epidemiology, cellular pathogenesis, clinical manifestations and management.

Coronavirus Disease 2019 (COVID-19) is a rapidly progressing global pandemic that may present with a variety of cardiac manifestations including, but not limited to, myocardial injury, myocardial infarction, arrhythmias, heart failure, cardiomyopathy, shock, thromboembolism, and cardiac arrest. These cardiovascular effects are worse in patients who have pre-existing cardiac conditions such as coronary artery disease, hypertension, diabetes mellitus, and coagulation abnormalities. Other predisposing risk factors include advanced age, immunocompromised state, and underlying systemic inflammatory conditions. Here we review the cellular pathophysiology, clinical manifestations and treatment modalities of the cardiac manifestations seen in patients with COVID-19.

A Unique Case of Mitral Valve Dehiscence Post-mitral Valve Repair Diagnosed Using 3D Transesophageal Imaging.

This is an interesting cardiovascular imaging case of a 70-year-old male who presented with heart failure symptoms after recent mitral valve repair with Carpentier-Edwards ring. Ring dehiscence was noted on transesophageal echocardiographic imaging which aided in guiding clinical and surgical courses.
