(a) An electrocardiogram performed before transcatheter aortic valve implantation (TAVI) shows sinus rhythm with second-degree AV block (Mobitz type 1), right bundle branch block, and left ventricular hypertrophy with repolarization abnormalities. (b) Post TAVI, a pacemaker check showed sinus rhythm with complete heart block.

A temporary pacemaker check revealed ventricular paced rhythm (99.4%) with underlying sinus rhythm and complete heart block (Figure 1(b)).
(a) The parasternal long-axis view on transthoracic echocardiography shows bulky calcification of the aortic valve (arrow). (b) The apical five-chamber view on transthoracic continuous-wave Doppler analysis shows a mean gradient of 48 mmHg.

Mild-to-moderate aortic valve regurgitation (Figure 2) also was seen.
This periprocedural fluoroscopic image shows deployment of a self-expanding TAVI Evolut PRO+ (Medtronic, Minneapolis, MN, USA) device at a depth of 3 mm in the aortic valve during rapid pacing.

TAVI 26-mm Evolut PRO+ (Medtronic, Minneapolis, MN, USA) was deployed during rapid pacing at a depth of 3 mm in the aortic valve (Figure 3). This led to a marked improvement of the transvalvular gradient with only mild paravalvular aortic regurgitation.
