the tricuspid valve (tv) is a complex structure. Unlike mitral and aortic valves, simultaneous visualization of the 3 TV leaflets cannot be achieved with 2-dimensional echocardiography (2DE) due to valve orientation with reference to the imaging planes. No 2D echo plane is parallel to the tricuspid valve. Therefore, there is no short-axis view for the tricuspid valve on 2DE. Three-dimensional echocardiography (3DE) supplements 2DE with detailed images of TV morphology. Tricuspid regurgitation (TR) secondary to blunt chest trauma is rare. 3DE provides a “surgeon view” of the valve to aid surgical planning. While functional TR secondary to right ventricular dilation is most common cause of TR, valve injury from device-lead or catheter placement/removal is increasing in incidence. 2DE is unable to completely visualize the intracardiac course of a lead or catheter as it usually does not lie in a single imaging plane. 3DE has the ability to define 3D spatial relationship of the TV with nearby intracardiac devices in real time. This report illustrates the diagnostic capability of 3DE in providing incremental anatomic information of the TV and its relation to adjacent structures and/or devices for prevention and management of traumatic TR (Figs. 1 to 4).⇓⇓⇓
