The Mitral/Aortic Flow Velocity Integral Ratio in Mitral Regurgitation.
The development of echocardiography was driven, in part, by a need to diagnose mitral regurgitation in patients undergoing finger fracture commissurotomy in the 1950s. Decades later, color Doppler became the cornerstone for noninvasive evaluation of mitral regurgitation. The authors present 2 cases of calcific mitral stenosis in which reliance on color Doppler in transthoracic echocardiography resulted in erroneous conclusions as to the severity of coexisting mitral regurgitation. The possible application of the Mitral to Aortic Flow Velocity Integral Ratio in such cases as a possible adjunct to grading mitral regurgitation is also discussed.

The Year in Cardiothoracic and Vascular Anesthesia: Selected Highlights from 2019.
This highlights in our specialty for 2019 begin with the ongoing major developments in transcatheter valve interventions. Thereafter, the advances in left ventricular assist devices are reviewed. The recent focus on conduit selection and robotic options in coronary artery bypass surgery are then explored. Finally, this special articles closes with a discussion of pulmonary hypertension in noncardiac surgery, anesthetic technique in cardiac surgery, as well as postoperative pneumonia and its outcome consequences.

Quantitative Transthoracic Echocardiography of the Response to Dobutamine in Cardiac Surgery Patients With Low Cardiac Output Syndrome.
To quantify the acute effects of dobutamine in postoperative low cardiac output syndrome (LCOS) using transthoracic echocardiographic, hemodynamic, and blood biomarker monitoring and to assess its association with clinical outcomes. ⋯ Early transthoracic echocardiographic assessment and the acute response to inotropic therapy may provide rapid and highly valuable information in the diagnostic workup and risk evaluation of patients with suspected LCOS after cardiac surgery.

The Association Between Pulsatile Cardiopulmonary Bypass and Acute Kidney Injury After Cardiac Surgery: A Before-and-After Study.
To investigate the association between pulsatile perfusion and cardiac surgery-associated acute kidney injury. ⋯ There was no association found between kidney injury and pulsatile perfusion. It is likely that there is either no association between pulsatile perfusion and reduced kidney injury or that the difference is extremely small.
