Valve Diseases

The tricuspid valve is currently the subject of much interest from echocardiographers and surgeons. Functional tricuspid regurgitation is the most frequent aetiology of tricuspid valve pathology, is characterized by structurally normal leaflets, and is due to annular dilation and/or leaflet tethering. A primary cause of tricuspid regurgitation with/without stenosis can be identified only in a minority of cases. Echocardiography is the imaging modality of choice for assessing tricuspid valve diseases. It enables the cause to be identified, assesses the severity of valve dysfunction, monitors the right heart remodelling and haemodynamics, and helps decide the timing for surgery. The severity assessment requires the integration of multiple qualitative and quantitative parameters. The recent insights from three-dimensional echocardiography have greatly increased our understanding about the tricuspid valve and its peculiarities with respect to the mitral valve, showing promise to solve many of the current problems of conventional two-dimensional imaging. This chapter provides an overview of the current state-of-the-art assessment of tricuspid valve pathology by echocardiography, including the specific indications, strengths, and limitations of each method for diagnosis and therapeutic planning.

The Impact

Abstract Purpose The exact correlation between the baseline left atrial (LA) volume (LAV) and atrial fibrillation (AF) radiofrequency catheter ablation (RFCA) outcomes and changes to the LA after AF RFCA has not yet been fully understood. We sought to evaluate the serial changes in the LAV and LA function after RFCA using 3D echocardiography. Methods Consecutive patients who received RFCA of paroxysmal (PAF) or persistent AF (PeAF) at our center between January 2013 and March 2016 were included. Real-time 3D apical full-volume images were acquired, and a 3D volumetric assessment was performed using an automated three-beat averaging method. The LAV index (LAVI) was calculated and the LA ejection fraction (LAEF) was calculated as [LAVmax − LAVmin]/LAVmax. Results Ninety-nine total patients were enrolled, and the mean age was 58.0 ± 8.2 years and 75 (74.7%) were male. There were 59 (59.6%) PAF patients and the remaining 40 (40.4%) had PeAF. AF recurred in 5 of 59 (8.5%) PAF and in 10 of 40 (25%) PeAF patients. The LAVImax increased on 1 day, decreased at 3 months, and then increased again at 1 year but was lower than that at baseline. The LAEF changes were similar to the volume changes but were more prominent in PeAF than PAF patients. The baseline 3D LAVImax was an independent predictor of AF recurrence after RFCA and the cut-off value was 44.13 ml/m2. Conclusion In our study, even after 3 months of scar formation due to ablation, structural remodeling of the LA continued. The changes were more prominent in the non-recurrent, PeAF patients.
