The case was managed surgically by retrieving and re-implanting the dislodged valve as a bailout strategy. CoreValve Transcatheter aortic valve replacement Figures Figure 1 Figure 2 Figure 3 INTRODUCTION TAVR, in the modern era of valvular disease management, is considered an attractive alternative to surgery in higher-risk patients with symptomatic aortic stenosis. 1 TAVR is associated with the potential for serious complications. Valve embolization (VE) is defined as the valve prosthesis movement during or after deployment such that it loses contact with the aortic annulus. 2 VE occurs in approximately 0.2% of cases using self-expanding Medtronic CoreValve. 1 VE of a partially or entirely deployed CoreValve prosthesis can be managed interventionally in most cases. 3 Other cases require Aortic Valve (AV) replacement using the conventional surgical approach. CASE REPORT A 78-year-old male was referred to our center with recently diagnosed symptomatic severe aortic stenosis after being evaluated for progressive exertional dyspnea. Transthoracic echocardiography revealed a mean trans-aortic pressure gradient of 56mmHg and AV area of 0.6 cm2 with an ejection fraction of 55%. Coronary angiography revealed minimal non-obstructive coronary artery disease. The patient refused surgical aortic valve replacement (SAVR) despite a low-risk conventional surgery (Society of Thoracic Surgeons Score, 1%); hence, he was scheduled for transfemoral TAVR. Based on the integrated measurements obtained by multi-slice spiral CT angiography, a 34 mm valve prosthesis was suggested; however, regarding the heavy calcification of the AV with a calcium score of 6367, the Heart Team decided to proceed with a 29mm valve prosthesis, to avoid the risk of annular rupture. Transfemoral TAVR was performed with the aid of transesophageal echocardiography (TEE) (Supplementary Video 1). under general anesthesia, followed by a surgical exploration of the right common femoral artery. After loading the delivery system over a J-tipped stiff guidewire and certainty about good planar angle positioning in a 5mm depth under the annulus (Fig. 1 A, Supplementary Video 2), the prosthesis was deployed under rapid pacing. With close monitoring by fluoroscopy, the inflow part of the self-expanding prosthesis was first deployed properly (Fig. 1 B, Supplementary Video 2), followed by expeditious deployment of the outflow part and after the team was satisfied with the valve position, the system was released (Fig. 1 C, Supplementary Video 2). As the delivery system was withdrawn following full deployment, the valve suddenly migrated into the ascending aorta (Fig. 1 D, Supplementary Video 3). TEE showed the migrated valve with its inflow part positioned just beyond the sinotubular junction (Fig. 1 E, Supplementary Video 4). After completely removing the guidewire and pigtail catheter, the final fluoroscopy and TEE images showed the free-floating, fully-expanded CoreValve prosthesis within the distal ascending aorta (Fig. 1 F, Supplementary Video 5 and 6). The patient’s hemodynamics deteriorated suddenly. Hence, the Heart team proceeded with emergent bailout surgery (Fig. 2 ). Median sternotomy was performed, and the “bouncing” valve prosthesis was palpable high in the ascending aorta, with its upper pole near the origin of the innominate artery and the lower pole at a lower point in the distal of the ascending aorta. Under cardiopulmonary bypass, a longitudinal aortotomy was performed (Fig. 2 A). The stent valve was then retrieved without damage (Fig. 2 B, Supplementary Video 7) and immediately submerged in ice-cold sterile saline. Cardiac arrest was achieved following direct intra-coronary administration of cardioplegia. The native AV was explored and showed a heavily calcified tricuspid valve with a bulkier calcification on the right coronary cusp, which seemed to be incompressible and resulted in complete immobility of this cusp (Fig. 2 C). The leaflets of the native AV were totally excised, and the annulus debrided of calcification. The heavy calcification of AV extended to the base of the anterior mitral valve leaflet, so decalcification of this valve was also performed. At the next step, the retrieved valve prosthesis was prepared for reimplantation (Fig. 3 ). Akin to the routine pre-TAVR rinsing and loading procedure, we immersed the prosthesis in a sterile bowl of ice-saline to shrink the nitinol stent frame, especially at the annulus level (Fig. 3 A). Multiple interrupted mattress sutures encircling the prosthesis annulus were placed (Fig. 3 B). After manual crimping of the lower pole of the stent, the prosthesis was lowered to the native aortic annulus and seated properly, and the sutures were tied and secured (Fig. 3 C). Finally, the coaptation of the leaflets was checked, and the aortotomy was closed. The patient was easily weaned off from cardiopulmonary bypass, and the surgery was completed after post-pump TEE, which confirmed the successful result of surgery with normal biventricular function, acceptable leaflet motion, and hemodynamic study (mean trans-aortic pressure gradient of 12mmHg) and a no para or transvalvular leakage (Supplementary Video 8). The operation time was 90 minutes, the extracorporeal circulation time was 62 minutes, and the cross-clamp time was 38 minutes. The patient was transferred to the intensive care unit, extubated 11 hours after surgery, and experienced a non-complicated postoperative course. He was discharged on the fourth day following surgery. Three months after surgery, the patient was asymptomatic, and follow-up TTE was within normal limits. DISCUSSION In this case, we believe that the bulky calcification with asymmetric distribution on the AV leaflets and the undersized valve prosthesis caused the failed valve deployment. Extensive calcification around the native valve is strongly associated with device failure, especially with self-expanding valves with non-uniform distribution of valvular calcium. 4 percutaneous approach can be attempted at first in the majority of patients with aortic embolization of the TAVR valve. 5 Self-expandable valves can be snared and pulled to a more distal aortic location. However, some reports indicate that such conservative approaches could not always be safe and even be life-threatening, especially with the self-expanding valve, which has an upper crown that may protrude through and perforate the aortic wall. 6 In the present case, even though the valve was embolized into the aorta, the heart team decided on the surgical removal approach due to unstable hemodynamics. In almost all previous cases of surgical removal of embolized TAVR valves, conventional bioprosthetic valves were implanted, so the embolized valve was left useless. 7 Mandegar et al. reported on recapturing and repositioning a displaced balloon-expandable Sapien 3 transcatheter heart valve after LV embolization. 8 CONCLUSION Surgical re-implantation of a dislodged CoreValve is safe, and this approach is feasible in low-income areas with limited availability of prosthetic valves in urgent settings.
