Correction

In the article by Piazza et al, "Anatomy of the Aortic Valvar Complex and Its Implications for Transcatheter Implantation of the Aortic Valve," which appeared in the August 2008 issue of the journal (Circulation: Cardiovascular Interventions 2008;1:74–81), the following corrections should be made.

On page 74, in the Abstract, the 3rd sentence should read: Such an appreciation of the anatomy helps better understand the optimal positioning for the prosthetic valve within the root of the aorta with respect to the coronary arteries, mitral valve, and the conduction system and may circumvent complications that can arise during its implantation.

On page 75, Figure 2 has been replaced to correct ascending aortic to read ascending aorta.

On page 78, in the Section entitled, "Location of the Coronary Arteries," the first sentence in paragraph 2 should read: In a recent study examining the aortic root with multislice computed tomography in 169 patients (ie, 150 patients with no or mild aortic stenosis and 19 patients with moderate or severe aortic stenosis), the mean distance from the level of the basal attachment point of the aortic valvar leaflets to the ostium of the left coronary and right coronary artery was 14.4±2.9 mm and 17.2±3.3 mm, respectively.²⁸

On page 80, in the section entitled, "What Imaging of the Aortic Valvar Complex Is Required Before Transcatheter Valvar Implantation?" 2nd paragraph, items 5 to 8 should read: (5) diameter of the left ventricular outflow tract; (6) the height and width of the sinus of Valsalva; (7) the height of takeoff of the coronary artery ostia with respect to the level of the basal attachment of the aortic valvar leaflets; and (8) thickness of the ventricular septum. Also, paragraph 5, last sentence should read: Of note, the diameter from the basal attachment of one leaflet to the basal attachment of an adjacent leaflet can vary depending on the view or projection used for measurement.

Same section, paragraph 6, first sentence should read: Indeed, in a study of 150 patients with no or mild aortic stenosis and 19 patients with moderate or severe aortic stenosis undergoing evaluation of the aortic root with multislice computed tomography, the mean distance from the basal attachment of one leaflet to the basal attachment of an adjacent leaflet was 26.3±2.8 and 23.5±2.7 mm on the coronal and sagittal views, respectively, indicating an oval shape of the aortic root at this level.²⁸

Last, on page 81, the authors for Reference 33 should read: Piazza N, Onuma Y, Jesserun E, Kint PP, Maugenest AM, Anderson RH, de Jaegere P, Serruys PW.

These errors have been corrected in the current online version of the article (http://circinterventions.ahajournals.org/cgi/content/full/1/1/74). The publisher regrets these errors.
