Coronary ostial eccentricity in severe aortic stenosis: Guidance for BASILICA transcatheter leaflet laceration.

Summary of "Coronary ostial eccentricity in severe aortic stenosis: Guidance for BASILICA transcatheter leaflet laceration."

Eccentricity of coronary ostial positions in relation to the aortic valve cusp may influence the target laceration location in BASILICA (Bioprosthetic or native Aortic Scallop Intentional Laceration to prevent Coronary Artery obstruction). Eccentricity of the coronary ostia in relation to coronary cusps of native and valve-in-valve transcatheter aortic valve replacement (TAVR) was not well described before.

Hemodynamics and Prognostic Impact of Concomitant Mitral Stenosis in Patients Undergoing Surgical or Transcatheter Aortic Valve Replacement for Aortic Stenosis.

Mitral stenosis frequently coexists in patients with severe aortic stenosis. Mitral stenosis severity evaluation is challenging in the setting of combined aortic stenosis and mitral stenosis because o...

Functional assessment of coronary stenosis with angiography-based Quantitative Flow Ratio compared with Fractional Flow Reserve in patients with severe aortic stenosis.

To investigate the diagnostic performance of quantitative flow ratio (QFR) in assessing the physiological relevance of coronary lesions in the presence of severe aortic valve stenosis (SAS).

Silent coronary artery disease in asymptomatic patients with severe aortic stenosis and normal exercise testing.

There are no data about the prevalence of silent coronary artery disease in asymptomatic severe aortic stenosis patients with normal exercise testing. Importantly, unmasking significant coronary arter...

Transcatheter aortic valve implantation versus surgical aortic valve replacement for severe aortic stenosis in people with low surgical risk.

Severe aortic valve stenosis (AS) is a major cause of morbidity and mortality worldwide. The definitive management for severe AS is aortic valve replacement (AVR). The choice of transcatheter approach...

Multimodality Imaging for the Assessment of Severe Aortic Stenosis.

Aortic stenosis is the most common type of valvular heart disease. Aortic stenosis is characterized both by progressive valve narrowing and the left ventricular remodeling response that ensues. In aor...

Bioprosthetic or Native Aortic Scallop Intentional Laceration to Prevent Iatrogenic Coronary Artery Obstruction (BASILICA) Prospective Investigation

Background: TAVR is a common therapy for people with heart problems. It stands for transcatheter aortic valve replacement, TAVR can be a better option than surgery. But it isn t safe for ...

Randomized Study for the Optimal Treatment of Symptomatic Patients With Low Gradient Severe Aortic Valve Stenosis and Preserved Left Ventricular Ejection Fraction

Medical and Biotech [MESH] Definitions

A pathological constriction that can occur above (supravalvular stenosis), below (subvalvular stenosis), or at the AORTIC VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.

Surgical treatment for severe AORTIC VALVE STENOSIS. Transcatheter aortic valve replacement (TAVR) is used as an alternative option in patients who are deemed at high risk or inoperable for traditional open-heart surgery.

The ratio of maximum blood flow to the MYOCARDIUM with CORONARY STENOSIS present, to the maximum equivalent blood flow without stenosis. The measurement is commonly used to verify borderline stenosis of CORONARY ARTERIES.

Small clusters of chemoreceptive and supporting cells located near the ARCH OF THE AORTA; the PULMONARY ARTERIES; and the coronary arteries. The aortic bodies sense PH; CARBON DIOXIDE; and oxygen concentrations in the BLOOD and participate in the control of RESPIRATION. The aortic bodies should not be confused with the PARA-AORTIC BODIES in the abdomen (which are sometimes also called aortic bodies).

A pathological constriction occurring in the region below the AORTIC VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.
