title: Doppler markers of elevated left atrial and ventricular filling pressure in a critically ill patient.
abstract: Accurate assessment of intracardiac flows by Doppler echocardiography may add important hemodynamic information in the critically ill patient. Detailed analysis of flow gradients through different sites and their correlation with timing of cardiac events may help us in better understanding the pathophysiology of the underlying disease. We report the clinical case of a 78-year-old patient with septic shock, in whom an A-dip of aortic regurgitation, shortening of diastolic filling, and diastolic mitral regurgitation were detected by Doppler analysis. Pathophysiologic explanation of these phenomena and their evolution after inotropic drug infusion are reported.
