Change in Lung Fluid Volume during Exercise in Patients with Exercise-Induced Mitral Regurgitation

open access: yesMedicina, 2022
Exercise-induced mitral regurgitation (MR) can be diagnosed during stress echocardiography testing. Remote dielectric sensing (ReDSTM) is a noninvasive electromagnetic-based modality to measure lung fluid levels.

Load dependence of the effective regurgitant orifice area in a sheep model of aortic regurgitation

open access: yes, 1991
Treatment of patients with aortic regurgitation with vasodilators reduces regurgitant volume, ventricular dilation and left ventricular mass. Although these effects are presumably due to afterload reduction, it is also possible that the aortic ...

Echocardiographic analysis of acute effects of percutaneous mitral annuloplasty on severity of secondary mitral regurgitation

open access: yesESC Heart Failure, 2020
Aims Percutaneous mitral annuloplasty (PMA) represents a new treatment option for secondary mitral regurgitation (SMR) being associated with higher morbidity and mortality.

Quantification of mitral regurgitation orifice area by 3-dimensional echocardiography: comparison with effective regurgitant orifice area by PISA method and proximal regurgitant jet diameter

open access: yes, 2002
Background: The evaluation of mitral regurgitation (MR) by 3-dimensional (3D) echo has generally been performed by reconstruction of Doppler regurgitant jets but there are little data on measuring anatomic regurgitant orifice area (AROA) directly from 3D

Association of Effective Regurgitant Orifice Area to Tricuspid Annular Plane Systolic Excursion Ratio with Outcomes After Tricuspid Annuloplasty

open access: yes, 2023
Background: Assessment of secondary tricuspid regurgitation (TR) severity does not correct for right heart function. We hypothesized that TR severity may be proportional or disproportional to the degree of right ventricular dysfunction and investigated ...

Effective aortic regurgitant orifice area: Description of a method based on the conservation of mass

open access: yes, 1991
The natural history of aortic regurgitation is incompletely understood in part because of the lack of a simple method to estimate the defect size. A method of determining the effective regurgitant orifice area that combines Doppler catheter and Doppler ...

Atrial Functional Tricuspid Regurgitation

open access: yesJACC: Advances
Background: Despite increasing clinical recognition of atrial functional tricuspid regurgitation (AF-TR), there remains limited literature regarding the characteristics, outcomes, and adverse prognosticators for this valve lesion.

Silk Fibroin for Cardiovascular Medical Devices: Review of Material Properties, Applications, and Clinical Potential

open access: yesAdvanced NanoBiomed Research, EarlyView.
Silk fibroin is an attractive natural biomaterial that can be engineered into diverse cardiovascular constructs, including vascular grafts, cardiac patches, heart valves, and stent coatings. Its tunable biological and mechanical properties have driven substantial preclinical progress; however, widespread clinical translation in cardiovascular ...

Evaluation of effective regurgitant orifice area of mitral valvular regurgitation by multislice cardiac computed tomography

open access: yes, 2010
SummaryObjectiveThe purpose of our study was to assess the diagnostic accuracy of multislice computed tomography (MSCT) for the identification and quantification of mitral valve regurgitation in comparison with transthoracic echocardiography (TTE ...

Hyperbranched poly‐L‐lysine surface‐engineered bioprosthetic heart valves with anti‐calcification, anti‐infection, and durability

open access: yesBMEMat, EarlyView.
The challenges of bioprosthetic heart valves (BHV) with respect to calcification, infection, and poor durability are tackled by surface engineering of hyperbranched poly‐L‐lysine (HBPL), providing a translational solution to improve long‐term valve performance.
