Delayed Presentation of Carcinoid Heart Disease and Subsequent Modified Healthcare Delivery in the COVID-19 Era.

• CHD is rare and typically affects the right-sided heart valves. • TTE is the reference standard for diagnosis and monitoring of CHD. • Multimodality imaging is part of a comprehensive evaluation of CHD.

Mechanical Circulatory Support in Transcatheter Aortic Valve Implantation in the United States (from the National Inpatient Sample).

Acute circulatory collapse may rarely occur during transcatheter aortic valve implantation (TAVI). In such cases, immediate mechanical circulatory support (MCS) as a bridge to remedial interventions may be required. To define the rate of MCS utilization in TAVI patients and identify the predictors of MCS utilization in a cohort of TAVI patients.
