We report the cases of three patients who underwent thoracic endovascular aortic repair for type B aortic dissection in which transesophageal echocardiography (TEE) was used to guide the procedure in addition to fluoroscopy. TEE was found to be advantageous because it can visualize vascular structures along with the guidewire and devices. Furthermore, it provides real-time hemodynamic and hematological information without the need for contrast injection or radiation exposure. Although TEE assessment requires expertise, the efficient use of TEE appears to be helpful for further improving the outcomes of endovascular surgery for aortic dissection.

Coronary sinus injury is a rare but critical complication of retrograde cardioplegia. Even after detection, successful repair with a pericardial patch is not always attained. Malalignment of the infusion cannula relative to the coronary sinus is likely to be partially responsible for the injury. Monitoring the location of the cannula tip can help prevent injury. Transesophageal echocardiography can indicate the vascular structure within which the cannula is located. This finding may be useful in preventing injury to the coronary sinus or middle cardiac vein.

Vascular closure devices (VCDs) are useful for reducing bed rest time after percutaneous catheterization procedure without manual compression at the femoral puncture site. Occlusion of the common femoral artery (CFA) related to VCDs has rarely been reported. Although catheter treatment for CFA occlusion may be the first choice, it may be insufficient. Surgical treatment should be performed immediately when catheter treatment for artery occlusion is deemed difficult. We report a case of surgical angioplasty performed for femoral artery occlusion by using a suturemediated device.
