A case of aortic valve leaflet tear and perforations after neocuspidization.

ESC Heart Fail 2019 Feb 18. Epub 2019 Feb 18.

Department of Cardiovascular Surgery, Chiba-Nishi General Hospital, Matsudo, Japan.

Although aortic valve (AV) replacement is a curative procedure for severe aortic stenosis, prosthetic heart valves have many disadvantages and cause serious complications. A new promising surgical procedure-aortic valve neocuspidization (AVNeo)-has recently been developed; it is an original method of AV reconstruction with autologous pericardium. It has been reported to yield excellent medium-term results with respect to durability and complications. Read More

Bicuspid Aortic Valve: An Update in Morphology, Genetics, Biomarker, Complications, Imaging Diagnosis and Treatment.

Front Physiol 2018 30;9:1921. Epub 2019 Jan 30.

Department of Ultrasound, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China.

The bicuspid aortic valve, a kind of heart disease that comes from parents, has been paid attention around the world. Although most bicuspid aortic valve (BAV) patients will suffer from some complications including aortic stenosis, aortic regurgitation, endocarditis, and heart dysfunction in the late stage of the disease, there is none symptom in the childhood, which restrains us to diagnose and treatment in the onset phase of BAV. Hemodynamic abnormalities induced by the malformations of the valves in BAV patients for a long time will cause BAV-associated aortopathy: including progress aortic dilation, aneurysm, dissection and rupture, cardiac cyst and even sudden death.

Aortic angle is associated with neo-aortic root dilatation and regurgitation following arterial switch operation.

Int J Cardiol 2019 Apr 11;280:53-56. Epub 2019 Jan 11.

Unité Médico-Chirurgicale de Cardiologie Congénitale et Pédiatrique, Centre de référence Malformations Cardiaques Congénitales Complexes - M3C, Paris, France; Radiology Department, Hôpital Universitaire Necker Enfants Malades, Paris, France.

Introduction: Neo-aortic root dilatation and regurgitation are common progressive long-term complications of the arterial switch operation (ASO) for transposition of the great arteries (TGA) with increasing clinical burden. While several risk factors have been identified, most are constitutional. The acute aortic angle commonly seen after ASO might alter aortic dynamics and facilitate progression of the neo-aortic root dilatation and aortic regurgitation, but insufficient data is available.

Patient-specific simulation of transcatheter aortic valve replacement: impact of deployment options on paravalvular leakage.

Biomech Model Mechanobiol 2018 Nov 20. Epub 2018 Nov 20.

Department of Biomedical Engineering, Stony Brook University, T15-090 Health Sciences Center, Stony Brook, NY, 11794-8151, USA.

Transcatheter aortic valve replacement (TAVR) has emerged as an effective alternative to conventional surgical valve replacement in high-risk patients afflicted by severe aortic stenosis. Despite newer-generation devices enhancements, post-procedural complications such as paravalvular leakage (PVL) and related thromboembolic events have been hindering TAVR expansion into lower-risk patients. Computational methods can be used to build and simulate patient-specific deployment of transcatheter aortic valves (TAVs) and help predict the occurrence and degree of PVL. Read More

The Division of Cardiology, Mayo College of Medicine, Mayo Clinic, Rochester, MN, United States of America.

Compared with the vast literature concerning the echocardiographic assessment of mitral, or aortic disease, the data concerning the evaluation of tricuspid regurgitation (TR) is very limited. In this review we summarized the present data concerning the assessment of TR. We review the present knowledge concerning the pathogenesis of TR showing that it is extremely multi-factorial, thus, when assessing patients with TR by echocardiography it is imperative to focus on four major aspects: evaluation of severity of TR, assessment of the etiology of TR, evaluation of the mechanism of TR and suitability for surgical or per-cutaneous repair.

Feasibility study of a synchronized diastolic injection with low contrast volume for proper quantitative assessment of aortic regurgitation in porcine models.

Catheter Cardiovasc Interv 2018 Nov 15. Epub 2018 Nov 15.

Imperial College London, London, United Kingdom.

Objectives: To evaluate the in vivo feasibility of aortography with one accurately timed diastolic low-volume contrast injection for quantitative assessment of aortic regurgitation (AR) post transcatheter aortic valve replacement (TAVR).

Background: With the rise of a minimalistic approach for TAVR, aortography (re)emerges as a pragmatic tool for AR assessment. In a mock circulation system, we have validated the accuracy of a single diastolic injection triggered by electrocardiogram (ECG) with low-contrast volume. Read More

Contemporaneous management of valvular heart disease and aortopathy in aircrew.

Heart 2019 Jan;105(Suppl 1):s57-s63

Royal Air Force Aviation Clinical Medicine Service, RAF Centre of Aviation Medicine, RAF Henlow, Bedfordshire, UK.

Valvular heart disease (VHD) is highly relevant in the aircrew population as it may limit appropriate augmentation of cardiac output in high-performance flying and predispose to arrhythmia. Aircrew with VHD require careful long-term follow-up to ensure that they can fly if it is safe and appropriate for them to do so. Anything greater than mild stenotic valve disease and/or moderate or greater regurgitation is usually associated with flight restrictions. Read More

Urgent transcatheter aortic valve replacement for severe acute aortic regurgitation following open mitral valve surgery.

Catheter Cardiovasc Interv 2018 Nov 8. Epub 2018 Nov 8.

Structural Heart and Valve Center, New York Presbyterian Hospital/Columbia University Medical Center, New York, New York.

Transcatheter aortic valve replacement (TAVR) is not currently approved for pure native valve aortic incompetence, and is typically performed on a compassionate basis in selected patients who are at high risk for conventional surgery. We describe the first use of TAVR to treat iatrogenic severe acute pure aortic incompetence following mitral valve surgery. A 71-year-old gentleman developed life-threatening acute aortic regurgitation (AR) within hours of a very challenging fifth open heart mitral valve replacement. Read More

Decision Making With Imaging in Asymptomatic Aortic Regurgitation.

JACC Cardiovasc Imaging 2018 Oct;11(10):1499-1513

Heart and Vascular Institute, Department of Cardiovascular Medicine, Cleveland Clinic, Cleveland, Ohio.

The authors review the optimal sequence of multimodality imaging studies in patients with chronic asymptomatic aortic regurgitation (AR). The initial questions in evaluating such patients are: 1) is AR severe; and 2) does it significantly impact the left ventricle? Although transthoracic echocardiography is usually able to answer these questions, a cardiovascular magnetic resonance imaging study might be necessary if the data from echocardiography are conflicting or inadequate. If AR is severe and the left ventricle is severely dilated, surgery is indicated. Read More

Two rare cases of congenital aortic stenosis showing a discrepancy between preoperative imaging diagnosis, intraoperative findings, and histopathological diagnosis.

J Cardiol Cases 2018 Jul 16;18(1):13-16. Epub 2018 Apr 16.

Department of Cardiology, Kokura Memorial Hospital, Kitakyushu, Japan.

Unicuspid aortic valve (UAV) is an extremely rare congenital heart valve abnormality while bicuspid valve (BAV) has been reported as one of the most common cardiac anomalies. With a UAV usually showing similar presentations to a BAV, such as aortic regurgitation or aortic stenosis (AS), it is challenging to differentiate them from each other in clinical settings. Despite some features shared between both valve disorders, there can be a clinical significance in distinguishing UAV from BAV for the management of patients with these heart anomalies. Read More
