  1. For prevalence and impact the numbers indicate the following levels: 1 = low, 2 = medium, 3 = high. For difficulty, scoring is reversed with numbers indicating the following levels: 1 = high, 2 = medium, and 3 = low. For prevalence and impact the numbers indicate the following levels: 1 = low, 2 = medium, 3 = high. For difficulty scoring is reversed with numbers indicating the following levels: 1 = high, 2 = medium, and 3 = low. This allows for a composite score where the higher numbers correspond to increasing relevance and applicability of POCUS
  2. LV left ventricular, LA left atrium, MV mitral valve, AV aortic valve, TV tricuspid valve, TEE transesophageal echocardiogram, RV right ventricle, TAPSE tricuspid annular plane systolic excursion, PHT pressure half-time, dTR pressure gradient measured in tricuspid regurgitation
