The Society for Cardiovascular Angiography and Interventions (SCAI) Think Tank is a collaborative venture that brings together interventional cardiologists, administrative partners, and select members of the cardiovascular industry community annually for high-level field-wide discussions. The 2021 Think Tank was organized into four parallel sessions reflective of the field of interventional cardiology: (a) coronary intervention, (b) endovascular medicine, (c) structural heart disease, and (d) congenital heart disease. Each session was moderated by a senior content expert and co-moderated by a member of SCAI’s Emerging Leader Mentorship program. This document presents the proceedings to the wider cardiovascular community in order to enhance participation in this discussion, create additional dialog from a broader base, and thereby aid SCAI, the industry community and external stakeholders in developing specific action items to move these areas forward.

The Baylor Scott & White Health system is comprised of hospitals throughout Central and North Texas, USA. A preprocedural SARS-CoV-2 screening and testing protocol was implemented at 25 hospitals within the system before aerosolizing or potentially aerosolizing procedures, including any requiring endotracheal intubation or conscious sedation. Patients were screened for any symptoms of SARS-CoV-2 infection and, if asymptomatic, tested within 72 h of the scheduled procedure. Testing was performed via nasopharyngeal swabs evaluated with reverse transcriptase–PCR assays (Table S1). All preprocedural tests were designated as such by the ordering provider to distinguish these tests from those ordered for other reasons. Procedures for patients testing positive were delayed unless considered as an emergency.

Among women with idiopathic dilated cardiomyopathy (IDC), the percent who develop heart failure (HF) in the peripartum period (during pregnancy or within 6 months of parturition) compared with those women who develop HF outside the peripartum period is unclear. We studied 72 women with IDC who underwent orthotopic heart transplantation for severe HF, the onset of which was in the peripartum period in 8 (11%) and outside the period in 64 (89%). Comparison of many clinical and morphologic variables between these 2 groups showed significant differences only in the ages of onset of HF, age when orthotopic heart transplantation was performed, and the frequency of the presence of diabetes mellitus. Examination of the hearts in the 2 groups disclosed no significant differences. Thus, separation of the peripartum IDC cases from the nonperipartum IDC cases by either clinical or cardiac morphologic variables is difficult.

Full text of this article.

This International Consensus Classification and Nomenclature for the congenital bicuspid aortic valve condition recognizes 3 types of bicuspid valves: 1. The fused type (right-left cusp fusion, right-non-coronary cusp fusion and left-non-coronary cusp fusion phenotypes); 2. The 2-sinus type (latero-lateral and antero-posterior phenotypes); and 3. The partial-fusion (forme fruste) type. The presence of raphe and the symmetry of the fused type phenotypes are critical aspects to describe. The International Consensus also recognizes 3 types of bicuspid valve-associated aortopathy: 1. The ascending phenotype; 2. The root phenotype; and 3. Extended phenotypes.

Described herein is a 48-year-old woman with metastatic ovarian cancer who developed aortic regurgitation considered clinically to be the result of infective endocarditis but operative resection of the three aortic valve cusps disclosed the valve lesions to be typical of non-bacterial thrombotic endocarditis (NBTE). Aortic regurgitation as a consequence of NBTE is rare but at least 9 cases have been reported previously.
