Echocardiography in Transcatheter Aortic Valve Replacement.

Heart Lung Circ 2019 Mar 8. Epub 2019 Mar 8.

Department of Cardiology, Leiden University Medical Center, Leiden, The Netherlands. Electronic address:

Transcatheter aortic valve replacement (TAVR) is a safe and efficient alternative for surgical valve aortic replacement in patients with symptomatic severe aortic stenosis who are inoperable or have a high risk for surgery. Randomised clinical trials have shown that TAVR is not inferior to surgical aortic valve replacement in intermediate-risk patients and ongoing trials will demonstrate the effects of TAVR in asymptomatic severe aortic stenosis patients and in patients with heart failure and moderate aortic stenosis. Continuous developments in procedural and post-procedural management along with increased operator experience and technical improvements and ongoing advances in imaging modalities (particularly in three-dimensional techniques), have reduced the procedural risks and the incidence of complications such as paravalvular aortic regurgitation.

Four-dimensional Flow MRI: Principles and Cardiovascular Applications.

Radiographics 2019 Mar 22:180091. Epub 2019 Mar 22.

From the Departments of Medical Imaging (A.A., N.C., G.A., S.S., V.M., M.Z.), Cardiology (P.G.), and Vascular Medicine (A.S.), Saint Joseph Hospital, 185 rue Raymond Losserand, 75014 Paris, France; and Department of Pediatric Cardiology, Necker Enfants Malades Hospital, Paris, France (D.S.).

In-plane phase-contrast (PC) imaging is now a routine component of MRI of regional blood flow in the heart and great vessels. In-plane PC MRI provides a volumetric, isotropic, time-resolved cine sequence that enables three-directional velocity encoding, a technique known as four-dimensional (4D) flow MRI. Recent advances in 4D flow MRI have shortened imaging times, while progress in big-data processing has improved dataset pre- and postprocessing, thereby increasing the feasibility of 4D flow MRI in clinical practice.

Int J Cardiovasc Imaging 2019 Feb 28. Epub 2019 Feb 28.

Division of Cardiology, Department of Medicine, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, Republic of Korea.

The management of asymptomatic patients with severe aortic regurgitation (AR) and preserved left ventricular (LV) systolic function remains controversial. We evaluated the predictive value of exercise stress echocardiography (ESE) in asymptomatic severe AR with preserved LV systolic function for identifying high risk patients who might benefit from early referral for surgery. Symptom-limited treadmill ESE was performed in 67 asymptomatic patients with severe AR (effective regurgitant orifice area > 30 mm, regurgitant volume > 60 ml) and preserved LV systolic function without LV dilatation [ejection fraction (EF) ≥ 50% and LV end-systolic diameter ≤ 50 mm].

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.

Assessment of Unicuspid Aortic Valve Stenosis Using Multimodality Imaging, X-ray Radiography and Raman Analysis.

Int Heart J 2019 Mar 10;60(2):482-488. Epub 2019 Jan 10.

Department of Biotechnology and Pharmaceutical Technology, Yuanpei University of Medical Technology.

Unicuspid aortic valve (UAV) is an extremely rare form of congenital cardiac malformation, leading to aortic stenosis (AS), aortic regurgitation (AR), or both. We report the case of a 55-year-old man with unicommissural UAV associated with severe AS and mild AR using different multimodality imaging approaches. The excised UAV isolated after aortic valve replacement exhibited an eccentric "teardrop" opening with a slit-shaped unicommissural structure. Read More

To repair or not to repair: a case report of atrioventricular groove hematoma during mitral valve surgery.

J Cardiothorac Surg 2019 Jan 9;14(1). Epub 2019 Jan 9.

Department of Thoracic and Cardiovascular Surgery, Yokohama Sakae Kyosai Hospital, 132 Katsura-cho, Sakae-ku, Yokohama, Kanagawa, 247-8581, Japan.

Background: Atrioventricular groove hematomas during mitral valve surgery range from simple hematomas to complex atrioventricular disruptions that cause frank rupture with massive bleeding and subsequent mortality. A small or moderate-sized hematoma is reported to be present in the left atrioventricular groove in 10 to 30% of all patients immediately after mitral valve replacement. Despite the fact that atrioventricular groove hematomas are inherently unstable and unpredictable, conservative strategies are recommended due to the high mortality associated with additional surgical repair.

Early failure of aortic bioprostheses: what are the mechanisms?

Curr Opin Cardiol 2019 Mar;34(2):173-177

Division of Cardiac Surgery, St. Michael's Hospital, University of Toronto, Toronto, Ontario, Canada.

Purpose Of Review: The purpose of this study is to review the contemporary evidence surrounding aortic bioprosthetic valve deterioration, with a focus on early failure of surgically implanted valves.

Recent Findings: Structural valve deterioration (SVD) remains the most frequent cause of premature bioprosthetic aortic valve failure. However, recent evidence suggests that SVD represents a spectrum, and that clinically silent hemodynamic valve deterioration frequently precedes and predisposes to overt SVD. Read More
