Intraoperative echocardiographic assessment of mitral regurgitation after mitral clip implantation: literature review

REC: Interventional Cardiology (English Ed.), 2022
Initially, percutaneous mitral clip emerges as an alternative to surgery in patients with severe mitral regurgitation (MR) and high surgical risk. Nonetheless, it is now also considered a first-line treatment in patients with left ventricular ejection ...

Assessment of Mitral Regurgitation Severity by measuring of Vena Contracta Area Using Transesophageal and Transthoracic Three-Dimensional Echocardiography [PDF]

Al-Azhar International Medical Journal, 2020
Background: Mitral regurgitation (MR) is one of the most common derangement of native valves and increases in prevalence with age. We aimed to compare the accuracy of the vena contracta area measurement (VCA) by 3-dimensional transesophageal (3D-TEE ...

Comprehensive assessment of the aortic valve in critically ill patients for the non-cardiologist. Part II: Chronic aortic regurgitation of the native valve

Anaesthesiology Intensive Therapy, 2021
Inadequate diastolic closure of the aortic valve causes aortic regurgitation (AR). Diastolic regurgitation towards the left ventricle (LV) causes LV volume overload, resulting in eccentric LV remodelling.

ASSESSMENT OF MITRAL REGURGITATION SEVERITY BY DIFFERENT ECHOCARDIOGRAPHIC METHODS IN COMPARISON WITH LEFT VENTRICLE ANGIOGRAPHY

The Iraqi Journal of Medical Sciences, 2016
Background:Proximal isovelocity surface area method and mitral regurgitatant jet estimation (with its ratio to left atrium) are reliable methods for estimation of mitral regurgitation severity aiding in management strategy, precluding the use of other ...

Quantification of Flow Rates and Flow Volumes in Valve Regurgitation Using 3-D High Frame-Rate Ultrasound

IEEE Open Journal of Ultrasonics, Ferroelectrics, and Frequency Control, 2023
Valve regurgitation is a cardiac condition caused by the incomplete closure of a cardiac valve. Untreated, this condition may result in cardiac failure.

Prevalence and Prognostic Importance of Massive Tricuspid Regurgitation in Patients Undergoing Tricuspid Annuloplasty With Concomitant Left-Sided Valve Surgery: A Study on Rheumatic Valvular Heart Disease

Frontiers in Cardiovascular Medicine, 2022
BackgroundThe presence of tricuspid regurgitation (TR) is very common in patients with concomitant left-sided valve disease. Recent studies have advocated an additional grading of massive TR that is beyond severe. The present study sought to characterize

Usefulness of Vena Contracta for Identifying Severe Secondary Mitral Regurgitation: A Three-Dimensional Transesophageal Echocardiography Study

Reviews in Cardiovascular Medicine, 2023
Background: In secondary mitral regurgitation (SMR), effective regurgitant orifice area by the proximal isovelocity surface area method (EROAPISA) evaluation might cause an underestimation of regurgitant orifice area because of its ellipticity compared ...

Disproportionate Mitral Regurgitation Determines Survival in Acute Heart Failure

Frontiers in Cardiovascular Medicine, 2021
Objectives: To assess the prevalence and impact of mitral regurgitation (MR) on survival in patients presenting to hospital in acute heart failure (AHF) using traditional echocardiographic assessment alongside more novel indices of proportionality ...
