| Aortic stenosis/calcification | 119 | 37 | 76 | 88 | 74 | 89 |
| Mitral regurgitation | 123 | 48 | 71 | 81 | 71 | 81 |
| Tricuspid regurgitation | 107 | 49 | 65 | 90 | 84 | 75 |
n total, the total number who underwent both PHHE and reference imaging; n pathology, total number with the described pathology; LV, left ventricle; RV, right ventricle; LA, left atrium; PPV, positive predictive value; NPV, negative predictive value.
