Role of Critical Care Medicine Training in the Cardiovascular Intensive Care Unit: Survey Responses From Dual Certified Critical Care Cardiologists.

Background Cardiovascular intensive care units ( CICUs ) have evolved from coronary care wards into distinct units for critically ill patients with primary cardiac diseases, often suffering from illnesses that cross multiple disciplines. Mounting evidence has demonstrated improved survival with the incorporation of dedicated CICU providers with expertise in critical care medicine ( CCM ). This is the first study to systematically survey dual certified physicians in order to assess the relevance of CCM training to contemporary CICU care.

Use of ultrasound enhancing agents in transesophageal echocardiography to improve interpretive confidence of left atrial appendage thrombus.

Background: The value of ultrasound enhancing agents (UEA) in patients undergoing transesophageal echocardiography (TEE) for the exclusion of left atrial appendage (LAA) thrombi prior to direct current cardioversion (DCCV) is evolving.

Methods: We retrospectively identified 88 consecutive TEEs, where a commercial UEA was used during LAA interrogation. De-identified non-enhanced (pre-UEA) and enhanced cine loop images (post-UEA) from the same subjects were randomly reviewed by four expert readers in a blinded fashion.

Automated volumetric flow quantification using angle-corrected color Doppler image.

We have developed a fully automated method for measuring volumetric blood flow with angle-corrected blood velocity from a color Doppler image. By computing the blood flow vector through a conduit, the angle of incidence between the direction of ultrasound beam and the direction of blood flow can be measured to correct the underestimated blood velocity. This correction immediately contributes to the improvement of measurement accuracy.
