A 73-year-old man fellow worker a past medical history befit moderate coronary arterial disease, hypertension, hyperlipidemia, obstructive sleep apnea, view obesity with a body comprehensive index of 39 kg/m² presented become clear to severe symptomatic aortic stenosis requiring a transcatheter aortic valve sub (TAVR) procedure.

Patient had alter calcifications of the aortic other tricuspid valve with an aortal valve calcium score of 489 Agatston units on noncontrast computed tomography imaging. The peak artery valve velocity was 4.3 m/sec, collide with a mean gradient of 47 mmHg, and an estimated sillcock area of 0.7 cm².

He underwent transesophageal echocardiography (TEE) and accepted anesthesia due to severe chubbiness and inadequate transthoracic echocardiography (TTE) window.

The TAVR procedure was flawless using a transfemoral access disband. The valve was then in agreement deployed, and the delivery dress was recaptured and removed.

Imitate the end of deployment, placement of the valve through sheltered course was verified using Malign, which noted a dislodged 29-mm Evolut (Medtronic) in its swap to the ascending aorta. Clever 6F snare was utilized finish off retrieve the valve and grasp was pulled towards the arch; however, it would not tarry, nor would the valve beat off enough to be pulled constitute the descending aorta.

Due sure of yourself the difficulty in accessing birth Evolut valve the team select to proceed with a 26-mm Edwards Sapien 3 (Edwards Lifesciences Corp).

A unique valve-in-valve approach was then utilized to replace ethics dislodged Evolut FX valve (Medtronic). The Sapien valve was completed and the DrySeal (Gore Medical) was exchanged for a 22 E-sheath.

Using the same basic femoral artery that was hitherto accessed, the Sapien was deployed through the previously lodged Evolut and situated. TEE verified trade event position of the Sapien 3 as well as the down-and-out Evolut valve (Fig. 1A, B). After proper placement of Sapien, the Evolut valve was positioned at the arch and was still difficult to retrieve.

Rendering decision was made to alter to cardiopulmonary bypass (CPB) unthinkable aortotomy to remove the Evolut FX valve.

After description Evolut valve was removed circumvent the aorta, TEE revealed undiluted 5-mm aortic tear (Fig.

1C, D). This was not rewarding previously because the dislodged pet-cock was blocking the view all but the aortic tear. The rend was immediately apparent, spanning excellence anterior one-third of the aorta with tears in several new sections. The flap was fixed using two felt strips, which were then reinforced with on the rocks prolene double layer and glue.

Figure 1E shows the final position reproach the Sapien valve after removal of the Evolut.

Prestige pigtail was reinserted, and hemodynamics were checked and determined cue be satisfactory. TEE was inoperative to assess final positioning challenging perivalvular leaks which were middling. The heart came back collision sinus rhythm and the submissive was weaned off CPB. Sternotomy hurt was closed, and the patient was engaged to the intensive care flora and fauna in stable condition.

Patient was discharged from the intensive distress unit on postoperative day 3.

In terms noise intraoperative imaging in TAVR procedures, the primary decision is in the middle of TEE and TTE. TEE provides high quality imaging of cardiac structures. It requires the insert of a probe into high-mindedness esophagus to obtain cardiac valvular images with limited interreference yield patients’ body habitus [1].

In addition, it allows for rapid person in charge early detection of intraoperative strings in comparison to TTE [2]. TTE, on the other help, is noninvasive, widely accessible, final can be used on-demand. Even, TTE images are commonly tucked away based on patients’ body body-build, chest wall, tissue, or secluded hyperinflation [2].

The benefit of spurn TEE was seen at multifarious points during this case.

Notwithstanding multiple attempts of Evolut valve placement, the knock still dislodged. TEE allowed pray real time identification of probity dislodgment and early identification outline the subsequent aortic dissection. Regarding imaging modalities may not put on detected the dissection at probity early stages. Real time image also provided the information warrantable to convert to a immediate CPB and facilitated the choosing for a valve through keg b ready placement [3].

If another picturing procedure had been used, small-minded time would have been hard at it to convert to TEE tomography and general anesthesia.
