Catheter-induced postextrasystolic potentiation in the assessment of severity of low-gradient aortic valve stenosis

, 2023
Background: Deciphering which patients with low-gradient aortic valve disease have severe stenosis can be difficult. We aimed to correlate the postextrasystolic potentiation (PESP) with dobutamine stress echocardiography and multidetector computed ...

Low-flow, Low-gradient Severe Aortic Stenosis: A Review

Heart International, 2023
Aortic stenosis (AS) is a common valve pathology experienced by patients worldwide. There are limited population-based studies assessing its prevalence; however, epidemiological studies emphasize that the burden of disease is growing. Recognizing AS relies on accurate clinical assessment and diagnostic investigations. Patients who develop severe AS are

Sheath‐to‐Artery Diameter Ratio: A Robust Predictor of Early Access‐Site Adverse Events in Percutaneous Procedures

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Vascular access site complications (VASCs) remain an important source of morbidity following percutaneous interventions. Although the sheath‐to‐femoral artery ratio is a recognized risk factor in transcatheter aortic valve implantation (TAVI), its role across a broader range of femoral procedures is less well defined.

PROGRESSION OF AORTIC STENOSIS IN THE ELDERLY DETECTED BY NONINVASIVE METHODS [PDF]

, 1988
One hundred eighty consecutive male patients, mean age of 64.6 years, who were referred to cardiac catheterization for the evaluation of aortic stenosis (AS), were studied using a noninvasive scoring system. The system is based upon 7 variables including:

Low-Flow Low-Gradient Aortic Stenosis [PDF]

Circulation: Cardiovascular Imaging, 2012
Aortic stenosis (AS) remains a common and important clinical entity and, when severe, is associated with significant morbidity and mortality. Fortunately, definitive surgical therapies have been developed that have significantly altered the natural history of this disease. The clinical challenge is to accurately assess AS severity and identify patients

Clinical Outcomes of the Allegra Transcatheter System in Bioprosthetic Aortic Valve Failure: A Multicentre Valve‐in‐Valve Registry

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Introduction The prevalence of bioprosthetic aortic valve failure is increasing due to the broader use of bioprosthetic valves, both surgical and transcatheter, and an ageing population. Registry data indicate a higher risk of coronary obstruction and elevated gradients following valve‐in‐valve transcatheter aortic valve implantation (TAVI ...

Different Types of Aortic Valve Stenosis in Patients Undergoing Transcatheter Aortic Valve Replacement

Structural Heart
Background: Transcatheter aortic valve replacement (TAVR) is an effective treatment in patients with “classical” concordant high-gradient aortic stenosis (AS). However, data on outcomes in patients with discordant AS are scarce.

Balloon Valvuloplasty of Aortic Valve Stenosis in Childhood: Midterm Results in a Children's Hospital, Mansoura University, Egypt

Clinical Medicine Insights: Cardiology, 2012
Background Balloon valvuloplasty was established as an alternative to surgery for treatment of aortic valve stenosis in childhood. Acute complications after balloon dilatation including aortic insufficiency or early death were described.

P152 THE EFFECT OF SURGICAL AORTIC VALVE REPLACEMENT ON AORTIC STIFFNESS AND THE PROGNOSTIC ROLE OF AORTIC STIFFNESS ON SURGICAL SUCCESS

Artery Research, 2018
Purpose/Background/Objectives: Aortic stiffness and hemodynamics are established biomarkers for cardiovascular events. Surgical aortic valve replacement (SAVR) remains the first choice of treatment in most patients with aortic stenosis.

Clinical outcomes of patients with low-flow, low-gradient, severe aortic stenosis and either preserved or reduced ejection fraction undergoing transcatheter aortic valve implantation [PDF]

, 2013
AIMS Our aim was to evaluate the invasive haemodynamic indices of high-risk symptomatic patients presenting with 'paradoxical' low-flow, low-gradient, severe aortic stenosis (AS) (PLF-LG) and low-flow, low-gradient severe AS (LEF-LG) and to compare ...
