In this report, we evaluate 56 consecutive adult patients who underwent standard two-dimensional (2D) and live three-dimensional transthoracic echocardiography (3D TTE), as well as left heart catheterization with aortography (45 patients) or cardiac surgery (11 patients), for evaluation of aortic insufficiency. Similar to the method we previously described for mitral insufficiency, aortic regurgitant vena contracta area (VCA) was obtained by 3D TTE by systematic and sequential cropping of the acquired 3D TTE data set. Assessments of aortic regurgitation (AR) by aortography and surgery are compared to measurements of VCA by 3D TTE and to 2D TTE measurements of vena contracta width (VCW). Aortographic or surgical grading correlated well with 2D TTE measurements of VCW (r = 0.92), but correlated better with 3D TTE measurements of VCA (r = 0.95), with improved dispersion between angiographic grades demonstrated by the 3D TTE technique. Live 3D TTE color Doppler measurements of VCA can be used for accurate assessment of AR and are comparable to assessment by aortography.

Transcatheter mitral valve implantation in severe mitral annular calcification: a case report.
Eur Heart J Case Rep
January 2025
HerzZentrum Hirslanden, 8032 Zurich, Switzerland.
Background: Mitral annular calcification (MAC) is characterized by severe calcification of mitral annulus and might be associated with both mitral regurgitation and stenosis. It is technically challenging for both surgical and percutaneous approach and is burdened by high mortality.
Case Summary: The present case report describes a complex case of mitral steno-insufficiency (baseline transvalvular gradient = 5 mmHg, effective regurgitant orifice area 0.
Impact of Right Ventricular to Pulmonary Artery Coupling on Survival Following Indirect Mitral Annuloplasty.
Catheter Cardiovasc Interv
December 2024
Department of Cardiology, Heart & Vascular Center, Rheinland Klinikum Neuss, Neuss, Germany.
Background: Right ventricular-to-pulmonary artery (RV-PA) coupling is an important predictor of long-term survival following transcatheter edge-to-edge repair. However, its impact on survival in patients undergoing indirect mitral annuloplasty is unknown. The study aimed to assess the impact of baseline RV-PA coupling on survival following indirect mitral annuloplasty in heart failure patients.

Article Synopsis
- - The MITRA-PRO registry shows that evaluating residual mitral regurgitation (MR) using 3D-Vena Contracta Area (VCA) is key for predicting patient survival after mitral valve repairs (TEER).
- - A study of 823 patients found that lower levels of residual MR (measured by 3D-VCA) correlate with reduced 1-year mortality, establishing 0.07 cm as a critical threshold for patient survival post-procedure.
- - The findings suggest that 3D-VCA is an effective tool for assessing MR during TEER, with lower residual MR levels associated with better survival outcomes.
Evaluation of Right Heart Structure and Function in Pacemaker-dependent Patients by Two-Dimensional Speckle Tracking Echocardiography: A 1-Year Prospective Cohort Study.
Rev Cardiovasc Med
November 2024
Cardiac Pacing and CIED Center, Beijing Anzhen Hospital, Capital Medical University, 100029 Beijing, China.
Article Synopsis
- Left bundle branch area pacing (LBBAP) is a secure method for heart pacing, but past studies primarily evaluated left heart function without considering the right heart's impact, prompting this study to investigate various pacing methods on right heart metrics.
- The study involved 90 patients with normal left ventricular function who were split into three groups: LBBAP, right ventricular septal pacing (RVSP), and right ventricular apical pacing (RVAP), examining various right heart indicators and interventricular synchrony.
- Results showed no significant changes in the LBBAP group for several heart function metrics, whereas significant declines were noted in the RVAP group, suggesting varying impacts of different pacing locations on heart function.
Echocardiographic Evaluation of Chronic Aortic Regurgitation: Comparison With Cardiac Magnetic Resonance and Implications for Guideline Recommendations.

Houston Methodist DeBakey Heart and Vascular Center, Houston, Texas, USA. Electronic address:
Background: Guidelines for echocardiographic evaluation of aortic regurgitation (AR) have not been validated against an independent quantitative standard.
Objectives: The aim of this study was to evaluate the accuracy of the ASE (American Society of Echocardiography) AR guidelines against cardiac magnetic resonance (CMR) and to develop simplified approaches for detection of significant AR.
Methods: Patients with AR underwent echocardiography and CMR <4 hours apart.
