The article abstract, "a case report of surgery for superior vena cava syndrome caused by ascending aortic aneurysm and pacemaker lead", was reviewed.The article presents a case study of a 70-year-old man with aortic regurgitation.It was reported on an unknown date 15 years ago, a 25mm sjm masters series mechanical heart valve was implanted.The patient subsequently underwent dual-chamber (ddd) pacemaker in the left anterior chest due to atrioventricular blockade.It was reported on an unknown date 3 years ago, the patient required a cardiac resynchronization therapy defibrillator (crtd) in the right anterior chest for ventricular tachycardia (vt).Later, it was reported on an unknown date 3 months ago, the patient presented with upper body and facial edema.A computed tomography (ct) revealed an area of contrast defect in the right internal jugular vein and subclavian vein confluence.It was reported that thrombus formation was suspected but it was also noted the patient had dilated peripheral internal jugular vein, distension of the azygos and jugular vein, and dilatation of the right precordial subcutaneous vein which led to diagnosis of superior vena cava syndrome.It was reported three-year-old ct showed dilation in the ascending aorta and sinus of valsalva, leading to new identification of a pseudoaneurysm in the ascending aorta.A decision was made to perform a bentall procedure and innominate vein bypass to treat superior vena cava syndrome.[the primary author was keisuke nakamura, showa university northern yokohama hospital, 35-1 chigasakichuo, tsuzuki ward, yokohama, kanagawa 224-0032, japan].Post-procedure complications: surgical intervention, heart block, tachycardia, edema, pseudoaneurysm.

As reported through a literature review a patient with aortic regurgitation who had a mechanical heart valve implanted.Subsequently, the patient underwent dual-chamber (ddd) pacemaker in the left anterior chest due to atrioventricular blockade.Later, an unknown date, the patient presented with upper body and facial edema.It was reported that thrombus formation was suspected but it was also noted the patient had dilated peripheral internal jugular vein, distension of the azygos and jugular vein, and dilatation of the right precordial subcutaneous vein which led to diagnosis of superior vena cava syndrome.It was reported three-year-old ct showed dilation in the ascending aorta and sinus of valsalva, leading to new identification of a pseudoaneurysm in the ascending aorta.A decision was made to perform a bentall procedure and innominate vein bypass to treat superior vena cava syndrome.A more comprehensive assessment could not be performed as the event was non-contemporaneously reported through a literature review and no device or individual patient information was received for analysis.Based on the available information, the root cause of the reported event could not be conclusively determined.There is no indication of a product quality issue with regards to manufacture, design, or labeling.
