The two methods, therefore, cross-validate and have the same end point - optimal VAD tip location. the radiographic cavoatrial junction, thus confirming both chest x-ray and ECG methods of catheter tip verification. node, were at the center of the SWEET SPOT™, i.e. In this same trial, the vast majority of the Sherlock 3CG guided catheter tips - whose technology targets the S.A. As such, it also became the standard of acceptability for our recently completed Sherlock 3CG trial. It was initially adopted practice wide by my group - Inland Imaging, Spokane, Washington in 2007 as the sole acceptable chest x-ray standard for VAD tip location - which it still is. As such, it allows for the necessary significant flexibility in acceptable VAD tip location based not only on patient, chest x-ray and catheter variables as just mentioned but also inserter variables such as societal affiliations, personal experience and personal convictions. It also encompasses the various leading societal recommendations for catheter tip location (see below). It is independent of patient factors such as age, size, patient position for chest x-ray, lung volume or type of VAD. The SWEET SPOT™ is the best anatomically based and radiographically confirmed practical approximation of the cavo-atrial junction. The SWEET SPOT™ extends from the lower third of the SVC to the most inferior extent of the right atrium - stopping at the frontal CXR's cardiophrenic angle (see Figure 01).
It was designed to be twice as wide as the lower third of the SVC to allow for the curving course of many catheter tips as they enter the right atrium - especially with left-sided access. on a frontal CXR, the initial outward bulge of the lower right cardiomediastinal margin due to the transition from the smaller, more tubular superior vena cava to the more capacious and rotund right atrium. It is centered over what I believe is the most accurate radiographic estimation of the cavo-atrial junction, i.e. The SWEET SPOT™ also has a fixed center point. This template is very easy to memorize and just as easy to teach. The template (see Figure 01) is simply compared in size to the CXR at hand. Depending on patient anatomy, it can exceed 8 x 4 cm. As such, it has no fixed length or width but does have fixed proportions with the craniocaudal length being twice the width on a frontal chest x-ray. This is tailored to the individual patient's chest x-ray. The SWEET SPOT™ is a rectangular template superimposed on a frontal CXR, whose margins and internal area are acceptable for VAD catheter tip position.
