The Influence of the Aortic Root Geometry on Flow Characteristics of a Bileaflet Mechanical Heart Valve [PDF]

arXiv, 2018
Bileaflet mechanical heart valves have one of the most successful valve designs for more than 30 years. These valves are often used for aortic valve replacement, where the geometry of the aortic root sinuses may vary due to valvular disease and affect valve performance. Common geometrical sinus changes may be due to valve stenosis and insufficiency. In

Aortic Stenosis and Small Aortic Annulus.

Circulation, 2019
The presence of a small aortic annulus poses a considerable challenge in the management of patients with severe aortic stenosis, especially in elderly women, where it is a very frequent finding.

Iatrogenic mitral stenosis following transcatheter aortic valve replacement (TAVR)

Indian Heart Journal, 2015
A 57 year old female underwent transcatheter aortic valve replacement (TAVR) for severe aortic stenosis. Mild iatrogenic mitral stenosis was noted intraoperatively. Attempts to reposition the device were hampered by aortic angulation.

The accessory renal arteries: A systematic review with meta‐analysis

Clinical Anatomy, EarlyView.
Abstract The accessory renal arteries (ARAs) are a well‐described variant of the renal vasculature with clinical implications for radiologists, surgeons, and clinicians. The aim of the present systematic review with meta‐analysis was to estimate the pooled prevalence of ARAs, including their variant number, origin, and termination, and to highlight ...

Aortic Valve Stenosis

Arteriosclerosis, Thrombosis and Vascular Biology, 2020
Aortic valve stenosis is the most prevalent heart valve disease worldwide. Although interventional treatment options have rapidly improved in recent years, symptomatic aortic valve stenosis is still associated with high morbidity and mortality.

Fractional Flow Reserve Directed Percutaneous Coronary Intervention Optimization Using High‐Definition Intravascular Ultrasound in Non‐ST‐Segment Elevation Acute Coronary Syndrome Versus Chronic Coronary Syndrome

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Intravascular ultrasound (IVUS)‐guided optimization of suboptimal fractional flow reserve (FFR) following percutaneous coronary intervention (PCI) results in a significant increase in both post‐PCI FFR and minimal lumen and stent areas (MLA and MSA, respectively).

The International TrifectaTM and EpicTM Valve‐in‐Valve Registry: Insights Into Clinical & Hemodynamic Outcomes

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Little is known about the clinical and hemodynamic outcome of valve‐in‐valve transcatheter aortic valve replacement (ViV‐TAVR) for failed Trifecta surgical aortic bioprotheses. Aims We aimed to compare outcomes of valve‐in‐valve transcatheter aortic valve replacement (ViV‐TAVR into failed TrifectaTM vs.

Association of Left Ventricular Global Longitudinal Strain With Asymptomatic Severe Aortic Stenosis: Natural Course and Prognostic Value

JAMA cardiology, 2018
Importance The optimal timing to operate in patients with asymptomatic severe aortic stenosis (AS) remains controversial. Left ventricular global longitudinal strain (LV GLS) may help to identify patients who might benefit from undergoing earlier aortic ...

Enhanced Drug Effect With Cutting Balloon Followed by Drug Coated Balloon in a Rabbit Model

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Drug‐coated balloon (DCB) are effective treatment options for patients with coronary artery disease and using of scoring or cutting balloon before the DCB usage were recommended. However, the effectiveness of lesion preparation with cutting balloons (CB) followed by DCB (CB + DCB) has not been evaluated before.
