  • assessment of aortic
  • There was a strong correlation between BP-mode and 3DTEE for assessment of aortic annulus diameter (r-value 0.88) with small mean difference (−0.2±0.9 mm) whereas the other modalities showed larger 95% confidence interval and modest correlation (2DTTE vs. 3DTEE, -6.3 to 0.9 mm, r=0.64 and 2DTEE vs. 3DTEE, -4.8 to 3.2 mm, r=0.61).

  • preoperative
  • We identified 47 patients with an preoperative aortic root diameter exceeding 60 mm (group A), 58 patients with an diameter between 50 and 60 mm (group B), and 18 patients with a diameter less than 50 mm (group C). The groups were compared regarding mortality, long-term survival, freedom from reoperation, freedom from severe and moderate aortic valve insufficiency (AI), and postoperative morbidity.

  • Conclusions- Our data show that the preoperative diameter of the aortic root has no impact on the longevity of the repair. (ahajournals.org)
  • 1-3 Tambeur and coworkers assumed a positive correlation between aortic root diameter and increased mechanical leaflet stress and speculated that valve-sparing aortic root replacement procedures in patients with a preoperative aortic root diameter in excess of 55 mm might lead to premature failure of the repair. (ahajournals.org)
  • To address the potential impact of preoperative aortic root diameter on the longevity of the repair we analyzed the affect of preoperative aortic root diameter on aortic valve function after valve-sparing aortic root reimplantion. (ahajournals.org)
  • embolization
  • It is therefore likely that anticoagulation with warfarin prevents thrombus formation (and subsequent embolization) on aortic plaques, just as it does in the left atrium, rather than directly affecting plaque size. (annals.org)
  • atherosclerosis
  • Aortic plaques are a manifestation of the general process of atherosclerosis in which there is a progressive accumulation of cholesterol and other lipids in the intimal-medial layer of the aorta with secondary inflammation, repetitive fibrous tissue deposition, and eventually luminal surface erosions and appearance of often mobile thrombi protruding into the lumen of the aorta.

  • This paper provides an extensive review of aortic atherosclerosis and the latest guidelines for its management. (springer.com)
  • Lumen
  • Thoracic Aortic Stent Migration to False Lumen in Aortic Dis. (lww.com)
  • Cardioplegic fluid may be infused through a lumen of the aortic occlusion device to stop the heart while the patient's circulatory system is supported on cardiopulmonary bypass. (google.com)
  • plaques
  • Aortic plaques may give rise to two types of emboli: thromboemboli and atheroemboli (cholesterol crystal emboli). (springer.com)
  • The mobile components of these complex plaques have been found to be thrombi , and serial transesophageal studies of the aorta have shown that these thrombi appear and disappear in different locations over time. (annals.org)
  • proximal
  • The distal end of the 4-branched graft was sutured to the proximal end of the OSG and distal aortic arch. (lww.com)
  • TAVI
  • The study population consisted of 50 patients retrospectively (24 men and 26 women, mean age 85±8 years of age) who all had undergone echocardiography examination prior to TAVI. (biomedcentral.com)
  • A multi-dimensional method is preferred to assess aortic annulus diameter in TAVI patients since there is risk of underestimation using single plane. (biomedcentral.com)
  • The impact of integration of this method in the algorithm of aortic annulus sizing on the outcome of patients undergoing TAVI should be examined in future studies. (nih.gov)
  • Endovascular
  • A side-firing fiberoptic laser is introduced through the aortic occlusion device in the endovascular technique to perform TMR. (google.com)
