Abbreviations: AR, aortic regurgitation; AV, aortic valve; MDCT, multi-detector computed tomography; TTE, transthoracic echocardiography; LMA, left main coronary artery; RCA, right coronary artery; PS off-axis view, parasternal off-axis view (a superiorly positioned parasternal short-axis view).
a Mean (±SD) heart rate during MDCT study for the cohort was 65 ± 9 beats per minute (bpm); all patients were in sinus rhythm during MDCT except for patient no. 1, 5, 7 and 11 who were in rate-controlled atrial fibrillation (maximum heart rates during study were 76, 68, 60 and 57 bpm, respectively).
b In the standard TTE acoustic windows, none of the patients’ LMA ostia could be visualized and only five patients’ (no. 1, 7, 11, 12 and 14) RCA ostia could be visualized.
