Mitral regurgitation Occurs in 60–90 % of patients with aortic stenosis Generally reduced after aortic valve replacement Early data indicate no increased mortality in patients with versus without mitral regurgitation…
Major vascular complications 1. Any thoracic aortic dissection 2. Access site or access-related vascular injury (dissection, stenosis, perforation, rupture, arteriovenous fistula, pseudoaneurysm, hematoma, irreversible nerve injury, or compartment syndrome) leading…
Fig. 23.1 Digital subtraction angiography (a) provides a more accurate characterization of vessel lumen and calcification (arrow) than routine angiography (b) in this patient with severe, calcified distal right common…
Fig. 10.1 (a–c) Distinguishing true AS from pseudo AS. In patients with LF-LG AS, as the continuity equation is less accurate and is known to underestimate the valve area, distinguishing…
