Point-of-care ultrasound: Uniting cardiology and nephrology at the bedside

Figure 2 Venous excess ultrasound waveforms illustrate a case of acute kidney injury and hyponatremia, where serial assessment of venous Doppler patterns during daily clinical exams demonstrated progressive improvement with diuretic therapy[22]. Notably, the patient had no pedal edema or visible jugular venous distention and was initially presumed to be hypovolemic. However, point-of-care ultrasound revealed elevated right atrial pressure and severe venous congestion. The patient had heart failure with reduced ejection fraction and a chronically dilated inferior vena cava (IVC), making reliance on IVC diameter alone inadequate for follow-up evaluation.
