Abstract

Purpose: Percutaneous coronary interventions after transcatheter aortic valve implantation have been found to be associated with difficulty in guiding catheter cannulation.

Methods and findings: Fixation of the guide catheter to the aortic valve frame using a coronary guidewire and snare was demonstrated to be a simple and reliable method of increasing guide catheter stability.

Introduction

A 78-year-old male moderately overweight patient presented with chief complaints of chest pain, shortness of breath for the past 2 months.

Prior treatments include: Transcatheter Aortic Valve Implantation (TAVI) 3 years prior and ICD implanted 1 year prior due to the cardiac arrest. Normal function of the left ventricle and normal gradient of the aortic valve were revealed by echocardiography. However, coronary angiography showed the ostial stenosis of LAD (VIDEO 1).

Methods and results

After insertion of the introducer, the guide catheter was advanced to the ostium of the coronary artery through the closest aortic valve frame cell. Then a coronary wire was inserted through the guiding catheter and the aforementioned cell (VIDEO 2). It was then moved through another cell in the valve frame into the lumen of the ascending aorta. The distal end of this coronary wire was trapped by the snare, which had been delivered from a second arterial access, at the level of the arch or ascending aorta (VIDEO 3). The distal part of the coronary wire was gripped firmly throughout the Percutaneous Coronary Interventions (PCI) process. The snare was then fixed (VIDEO 4). This approach helps achieve reliable and stable fixation of the guide catheter.

VIDEO 4. Writing of LAD and Cx. Two coronary guidewires were inserted sequentially in the distal parts of the LAD and intermedia. Predilation with a 2.0-20.0 mm balloon of the distal left main and proximal parts of LAD was performed.

Provisional stenting of the left main and the proximal part of the Left Anterior Descending (LAD) artery was performed without any challenges. Initial coronary angiography revealed severe calcinosis of the bifurcation of the left main, LAD, and the 90º angle between them, which could present difficulties for balloon and stent insertion. Two coronary guidewires were inserted sequentially in the distal parts of the LAD and intermedia (VIDEO 5). Predilation with a 2.0 mm-20.0 mm balloon at 12 atm of the distal left main and proximal parts of LAD was performed, but success was minimal (VIDEO 6). For this reason, predilation with a 2.25-15.0 non-compliant balloon at 17 atm was performed and a Resolute Onyx stent 3.0 mm- 22.0 mm was implanted in the left main and proximal part of LAD (VIDEO 7). Proximal optimization therapy with a 3.5-12.0 noncompliant balloon was performed as the next stage (VIDEO 8). The final result is shown in the VIDEO 9.

Echocardiography was performed after the procedure to assess the function of the aortic valve which did not reveal any damage of the flaps (VIDEO 10). The patient noted a significant improvement in his well-being and was discharged three days after the procedure.

Discussion and conclusion

Coronary angiography and PCI will become increasingly required in patients after TAVI [1]. Several reports have shown that there are technical difficulties with coronary engagement, particularly in patients with Evolut [2,3]. This difficulty may be due to the following factors the frame waist is narrower than the aorta and there was more space between the frame and the coronary ostia, TAVI commissural post, bulky old leaflet. Some authors suggest the use of an Extension Catheter Guidion for stenting [4]. The most interesting finding in this case was that the frame can actually help in supporting the guiding catheter. This finding was unexpected and suggests that the fixation of the guiding catheter improve coronary engagement significantly after using this technique. A possible explanation for this benefit might be during PCI treatment of the chronic total occlusion and complex stenosis. This method finding cannot be applied to patients after TAVI with other valve types.

The patient was seen 3 months following stenting. No clinical concerns were noted; the patient exhibited no initial symptoms and reported no complaints. In conclusion, fixation of the guide catheter to the aortic valve frame using a coronary guidewire and snare was demonstrated to be a simple and reliable method of increasing guide catheter stability.

Learning objectives

Case; The clinical case described here a method of effective guide catheter fixation after TAVI. To obtain insure reliable support of guiding catheter for PCI after TAVI.
