Patient selection: symptomatic aortic stenosis
Patient evaluation: Doppler echocardiography
Factors associated with an unfavorable outcome following TAVI without predilation:
(1) aortic valve area < 0.4 square cm
(2) eccentric and/or irregular orifice (not central)
(3) calcification Grade 3 (severe)
(4) restricted mobility of aortic cusps Grade 3 (severely restricted)
(5) calcifications of the left ventricular outflow tract (LVOT)
(6) calcium nodules near coronary ostia or at the LVOT
(7) aortic regurgitation Grade 3 (severe)
where:
• Grades for calcification, mobility and regurgitation went from 0 to 3.
The presence of unfavorable factors was associated with complications. The absence of unfavorable factors was associated with procedural success.
