Cardiac CTA as a Replacement for Esophageal Echocardiography After LAAC

Objective Monitoring of the device after Left Atrial Appendage Closure (LAAC) is crucial for evaluating the positioning of the occluder, peri-device leak (PDL), and device-related thrombus (DRT). Currently, data on the role of Cardiac CT Angiography (CCTA) after LAAC is limited. We compared CCTA with Transesophageal Echocardiography (TEE) in patients who successfully underwent LAAC. Methods … Read more

Understanding The Basic Architecture Of High-Speed DAC

The DAC is not merely the reverse process of the ADC. The simplest architecture of a DAC is the current steering circuit. A DAC is designed to inject or extract a certain amount of current into or from a load. Ohm’s law relates this current to the output voltage. In this example, if the full-scale … Read more
