Classical supravalvar aortic stenosis and peripheral pulmonary stenosis [PDF]

, 2014
Supravalvar aortic stenosis as well as peripheral pulmonary stenosis are rare forms of congenital heart disease, which occur, however, relatively frequently in association.

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 ...

Predictors of Outcomes in Low-Flow, Low-Gradient Aortic Stenosis [PDF]

Circulation, 2008
Background— Patients with low-flow, low-gradient aortic stenosis have a poor prognosis with conservative therapy but a high operative mortality if treated surgically. Recently, we proposed a new index of aortic stenosis severity derived from dobutamine stress echocardiography, the projected aortic ...

Estenosis aórtica de bajo flujo y bajo gradiente

Revista Colombiana de Cardiología, 2019
Resumen: La estenosis valvular aórtica es la valvulopatía más frecuente y en los últimos años ha sido admirable el avance tanto en su aproximación diagnóstica como terapéutica, dado el advenimiento del reemplazo de válvula aórtica transcatéter y ...

Clinical Impact of Adherence to Fractional Flow Reserve Guidance in Acute Coronary Syndrome

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Fractional flow reserve (FFR) is established to guide revascularization in stable coronary disease and non‐culprit lesions in acute coronary syndromes (ACS). However, real‐world adherence to FFR guidance across the spectrum of ACS presentations, including ambiguous culprit scenarios, remains incompletely characterized.

Dilemma in the therapeutic management of low-gradient aortic stenosis

, 2017
Purpose of review : Grading of aortic stenosis is essential in aortic stenosis management patients. However, despite clear thresholds provided in the guidelines, up to 30% of patients have discordant grading of aortic stenosis. The management of patients

Gutter Rotation Technique for Percutaneous Ipsilateral Retrieval of a Ruptured SAPIEN‐3 Balloon

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Balloon rupture during transcatheter aortic valve replacement (TAVR) with balloon‐expandable valves is a rare but potentially serious complication that may result in incomplete valve expansion, difficult device retrieval, and vascular injury.

Low-Flow Severe Aortic Stenosis

, 2017
The definition of severe aortic stenosis has classically and retrospectively been based on the natural history of patients with medically managed aortic stenosis and preserved left ventricular function in an era where surgical aortic valve replacement ...

Paradoxical Normal‐Flow Aortic Stenosis Despite Reduced Left Ventricular Ejection Fraction: Insights From the Randomized COMPARE‐TAVI 1 Trial

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background The hemodynamic profile and remodeling patterns of paradoxical low‐flow, low‐gradient aortic stenosis are well understood. However, some patients with severe aortic stenosis exhibit eccentric remodeling with enlarged left ventricular cavities,

Spatial Mismatch Between Angiographic Obstruction and Plaque Destabilization in Acute Coronary Syndromes: A Conceptual Narrative Review

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT The identification of the “culprit lesion” in acute coronary syndromes (ACS) traditionally relies on coronary angiography, assuming that the most severe stenosis, abrupt occlusion, or largest filling defect marks the site of plaque destabilization.
