Patient: An 82 year old female patient presented to the ER with symptoms and signs of congestive heart failure.

Initial Examination: She had a history of well controlled hypertension treated with beta blockers and diuretics by her primary care physician. On cardiac auscultation a mid-systolic ejection murmur was noted with diminished S2 heart sound. Her jugular veins were dilated and mild lower limb edema was present.

Kosmos POCUS Examination: Bedside examination with KOSMOS revealed severely impaired left ventricular systolic function. The aortic valve was heavily calcified and had severe stenosis. Moderate functional mitral regurgitation was also present. Patient was treated with intravenous diuresis resulting in improvement of her symptoms. A subsequent coronary angiogram revealed no coronary stenoses. She was scheduled for a TAVI procedure.

PLAX view showing dilated left ventricle with severely impaired overall systolic function. Diffuse hypokinesis of LV walls is seen. The aortic valve is heavily calcified and not opening well. There is symmetric tethering of both mitral valve leaflets due to LV remodeling. There is also mild pericardial effusion.

A4C view showing dilated LV with severely impaired systolic function. The RV has normal size and systolic function. There is also bi-atrial enlargement. A small pericardial effusion is evident.

PW LVOT signal showing reduced forward LV stroke volume

Figure 3
Maximum LVOT velocity measured at 0.54 m/s with PW, suggestive of low flow state.

Video 16
A4C view with color showing mild functional tricuspid regurgitation. There is also color flow inside the RA coming from the IAS, suggestive of a patent PFO with left to right shunt due to increased LA pressure.
