Summary of "Impact of suture techniques for aortic valve replacement on prosthesis-patient mismatch."

Many variables may affect the hemodynamic performance of the aortic valve prosthesis, and suture technique remains an important factor for determining maximum valve performance. The objective of this study was to determine the suture technique that produces better hemodynamic performance for aortic valve replacement (AVR).

First Two Brazilian Cases: Correction of Ascending Aortic Aneurysm and Aortic Valve Stenosis with Sutureless/Rapid Deployment Aortic Prosthesis.

Ascending aortic aneurysm is usually associated with aortic valve diseases, especially aortic stenosis. The standard technique involves the substitution of the dilated aortic segment with a Dacron tub...

Transcatheter aortic valve replacement becomes an equivalent alternative to surgical aortic valve replacement also in low-surgical-risk patients. Prosthetic valve endocarditis following transcatheter ...

Prosthesis-Patient Mismatch after Surgical Aortic Valve Replacement: Neither Uncommon nor Harmless.

Prosthesis-patient mismatch (PPM) after surgical aortic valve replacement (SAVR) is an issue that has been overlooked (not to say neglected). Cardiac surgeons must bear in mind that this is a real pro...

Impact of valvular resistance on aortic regurgitation after transcatheter aortic valve replacement according to the type of prosthesis.

The impact of aortic valvular resistance (VR) on the degree of post-transcatheter aortic valve replacement (TAVR) aortic regurgitation (AR) remains unclear. The objective of the study was to investiga...

Mechanical versus biological valve prosthesis for surgical aortic valve replacement in patients with infective endocarditis.

The optimal choice of valve prosthesis in surgical aortic valve replacement for infective endocarditis (IE) is controversial. We studied outcomes after mechanical versus biological prosthetic valve su...

Medical and Biotech [MESH] Definitions

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 downward displacement of the cuspal or pointed end of the trileaflet AORTIC VALVE causing misalignment of the cusps. Severe valve distortion can cause leakage and allow the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to aortic regurgitation.

Pathological condition characterized by the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to regurgitation. It is caused by diseases of the AORTIC VALVE or its surrounding tissue (aortic root).

A type of constriction that is caused by the presence of a fibrous ring (discrete type) below the AORTIC VALVE, anywhere between the aortic valve and the MITRAL VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.

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.
