Department of Cardiology, Inselspital, Bern University Hospital, University of Bern, Bern, Switzerland. Electronic address:

As transcatheter aortic valve replacement becomes a more dominant treatment option across all risk profiles, the frequency of encountering patients with multivalvular disease will increase. Furthermore, percutaneous interventions to treat other valvular lesions are also evolving. Understanding the clinical implications and treatment options for a second valvular lesion is becoming increasingly important to guide heart team decisions, and this paper aims to review the evidence around these situations.

Mitral regurgitation after transcatheter aortic valve replacement.

J Thorac Dis 2020 May;12(5):2926-2935

Department of Cardiovascular Surgery, Università Campus Bio-Medico di Roma, Rome, Italy.

Patients undergoing transcatheter aortic valve replacement (TAVR) might have an associated significant MR that can potentially lead to left ventricular (LV) failure after procedure. Considering the specific alterations in the mitral valve in TAVR scenario and the widespread use of TAVR in recent years, it appears important to know and understand the anatomical, functional and clinical implications to develop adequate strategies for the future. Patients with severe mitral regurgitation (MR) have been generally excluded from randomized clinical trials, making poor the impact that associated MR can have on clinical outcomes after TAVR.

Anticipating the management of Streptococcus agalactiae infective endocarditis.

JAAPA 2020 May;33(5):1-4

In the Department of Anesthesiology and Critical Care Medicine at Johns Hopkins Medical Institutions in Baltimore, Md., Gregory Schalla is a PA resident and Michael Grant is an assistant professor. The authors have disclosed no potential conflicts of interest, financial or otherwise.

A patient who presented after falling out of bed had signs of right-sided stroke, which, after imaging, was suspicious for embolism with cardiac origin. Further investigation revealed a large aortic valve vegetation with mild aortic insufficiency, and the patient eventually developed heart failure requiring surgical intervention. Infective endocarditis is slowly becoming more prevalent, and clinicians should have a high index of suspicion when patients present with common complications of this disease, such as valvular dysfunction, heart failure, or stroke.

Evaluating the Portability of an NLP System for Processing Echocardiograms: A Retrospective, Multi-site Observational Study.

AMIA Annu Symp Proc 2019 4;2019:190-199. Epub 2020 Mar 4.

Weill Cornell Medicine, New York, NY.

While natural language processing (NLP) of unstructured clinical narratives holds the potential for patient care and clinical research, portability of NLP approaches across multiple sites remains a major challenge. This study investigated the portability of an NLP system developed initially at the Department of Veterans Affairs (VA) to extract 27 key cardiac concepts from free-text or semi-structured echocardiograms from three academic edical centers: Weill Cornell Medicine, Mayo Clinic and Northwestern Medicine. While the NLP system showed high precision and recall easurements for four target concepts (aortic valve regurgitation, left atrium size at end systole, mitral valve regurgitation, tricuspid valve regurgitation) across all sites, we found moderate or poor results for the remaining concepts and the NLP system performance varied between individual sites.

The impact of the aortic cusps fusion pattern and valve disease severity on the aortic wall mechanics in patients with bicuspid aortic valve.

Int J Cardiovasc Imaging 2020 Apr 17. Epub 2020 Apr 17.

Department of Cardiology, Congenital Heart Diseases and Electrotherapy, Silesian Center for Heart Diseases, Faculty of Medical Science in Zabrze, Medical University of Silesia, Katowice, Poland.

The ascending aorta dilatation in the bicuspid aortic valve (BAV) patients is often attributed to congenital abnormalities of the aortic wall, but it may be related to hemodynamic disturbances in the course of BAV disease. At present, ascending aortic diameter is used as almost sole but weak predictor of aortic dissection and rupture in BAV. We examined the association between aortic wall mechanics and severity of aortic valve disease including different cusps fusion patterns using conventional echocardiography and tissue Doppler imaging (TDI).

Randomised comparison of a balloon-expandable and self-expandable valve with quantitative assessment of aortic regurgitation using magnetic resonance imaging.

Neth Heart J 2020 May;28(5):253-265

Department of Cardiology, University Medical Centre Utrecht, Utrecht, The Netherlands.

Introduction: Transcatheter aortic valve implantation (TAVI) is a safe and effective treatment for inoperable, intermediate- or high-risk patients with severe symptomatic aortic stenosis and has been associated with excellent clinical outcomes. A clinically relevant remaining problem is aortic regurgitation (AR) post-TAVI, which is associated with increased mortality. Therefore, we conducted a prospective randomised trial to assess the safety and efficacy of a first-generation self-expandable valve (SEV; CoreValve) and a third-generation balloon-expandable valve (BEV; Sapien 3) with respect to clinical outcomes and AR as determined quantitatively by magnetic resonance imaging (MRI).

Predictors of Bicuspid Aortic Valve-Associated Aortopathy in Childhood: A Report From the MIBAVA Consortium.

Circ Cardiovasc Imaging 2020 03 17;13(3):e009717. Epub 2020 Mar 17.

Division of Cardiology, Department of Paediatrics, The Hospital for Sick Children, University of Toronto, Canada (M.G., R.R., C.M., S.M., Ch.-P.S.F., C.M., L.M.).

Background: Bicuspid aortic valve (BAV) is the most prevalent congenital heart defect affecting 1% to 2% of the population. It is associated with ascending aorta dilatation. Valve morphology, aortic stenosis (AS), and aortic insufficiency (AI) have been proposed as potential risk factors; however, evaluating their role is difficult, as these factors are inherently related.

Long-Term Risk Factors for Dilatation of the Proximal Aorta in a Large Cohort of Children With Bicuspid Aortic Valve.

Circ Cardiovasc Imaging 2020 Mar 17;13(3):e009675. Epub 2020 Mar 17.

Department of Pediatrics, Centre Hospitalier Universitaire Sainte-Justine, Montreal, Canada (A.F., N.D.).

Background: Patients with bicuspid aortic valve (BAV) have a higher risk of developing aortic valve dysfunction and progressive proximal aorta dilatation, which can lead to aortic dissection. To this day, identification of children at risk of developing severe aortic dilatation during their pediatric follow-up is still challenging because most studies were restricted to adult subjects. The overarching goal of this study was to identify risk factors of aortic dilatation in children with BAV. Read More
