| Popis: | An 87-year-old man was admitted due to congestive heart failure. He had a history of coronary artery bypass surgery, chronic atrial fibrillation, chronic kidney disease, and chronic obstructive pulmonary disease on home oxygen therapy. Transthoracic echocardiography showed preserved left ventricular ejection fraction (LVEF = 54%) with no remarkable LV hypertrophy but low-gradient severe aortic stenosis (AS) (mean pressure gradient [MPG] 28 mm Hg, aortic valve area [AVA] 0.7 cm2, Panel A ) with severely calcified and reduced mobility aortic … |
