Real-time 3-dimensional echocardiography is a recently developed imaging technique that provides unique information on spatial geometry in real time. We described an asymptomatic patient with hypertrophic obstructive cardiomyopathy for whom 3-dimensional echocardiography was performed after intravenous injection of perfluorocarbon-filled microbubbles. It resulted in enhancement of the left ventricular endocardial border delineation and myocardial perfusion in the hypertrophic septum. A clear visualization of the entire course of the left anterior descending coronary artery and its septal perforator branches was obtained. This case illustrates the potential of real-time 3-dimensional echocardiography to improve the anatomic evaluation of coronary arteries, especially when combined with contrast agents.

Background: Transcatheter tricuspid valve edge-to-edge repair (T-TEER) has been reported to be associated with right ventricular reverse remodeling (RVRR). Data on the temporal evolution of this phenomenon are scarce.
Objectives: The aim of this study was to evaluate RVRR over the course of 2-year follow-up after T-TEER using sequential 3-dimensional echocardiograms (3DE).

Background: Pacemaker and implantable cardioverter-defibrillator (ICD) lead placement traditionally uses fluoroscopy, often with inaccurate lead placement on the free wall rather than on the ventricular septum, with associated longer QRS duration and pacemaker-induced cardiomyopathy while exposing staff and patients to radiation.
Objective: We sought to determine whether transesophageal 3-dimensional echocardiography (3DE) guidance improves lead placement accuracy in the ventricular septum, results in shorter paced QRS durations, and reduces fluoroscopy exposure.
Methods: In a single-center case-control study, 3DE guided right ventricular or atrial pacemaker and ICD leads to the desired location, with fluoroscopy used per operator preference.
Step-by-Step Transcatheter Tricuspid Valve Replacement Using the LuX-Valve Plus System.
JACC Case Rep

Division of Cardiology, Department of Medicine and Therapeutics, Prince of Wales Hospital, Chinese University of Hong Kong, Hong Kong, China.
The LuX-Valve Plus is a novel radial force-independent orthotopic transjugular transcatheter tricuspid valve replacement device proven to be effective in TR reduction. We describe preprocedural assessment for eligibility and procedural planning by means of computed tomography as well as procedural steps of device implantation under multimodality imaging guidance including transesophageal echocardiography (TEE), intracardiac echocardiography (ICE), and fluoroscopy: steering into the right ventricle, leaflet capture by graspers, fine valve adjustment, and septal anchor deployment. Potential pitfalls are avoided by achieving optimal alignment by means of TEE multiplanar reconstruction to steer the delivery system, and using mid-esophageal and deep gastric views of 3-dimensional TEE and supplementary ICE to visualize the graspers for leaflet capture, especially when TEE imaging is technically challenging.

Background: The prognostic value of 3-dimensional (3D)-left ventricular global longitudinal strain (LVGLS) in recipients of heart transplant (HT) reremains unknown. This study aimed to determine whether 3D-LVGLS was the more powerful predictor of poor outcomes in recipients of HT compared with 2-dimensional (2D)-LVGLS.
Methods And Results: All consecutive adult patients who received HT and underwent at least 1 comprehensive 2D and 3D transthoracic echocardiographic examination for clinical surveillance were retrospectively enrolled.
