Hospital mortality was 2.2%, as one patient died due to a fungal infection. Twelve patients( 26.7%) experienced complications during hospitalization. The 3- and 5-year overall survival rates were 97.7% and 88.0%, respectively. Freedom from reoperation was 93.7% and 93.7% at 3 and 5 years, respectively. One patient underwent re-aortic valve replacement due to a stuck valve, and one underwent re-Bentall due to a seroma.

{"title":"[Precautions for Coronary Artery Reconstruction in Aortic Root Replacement].","authors":"Goro Takahashi, Yoshikatsu Saiki","doi":"","DOIUrl":"","url":null,"abstract":"Aortic root replacement is based on the Bentall procedure, and if appropriate cases are selected, valve-sparing surgery has good results. However, peri-operative myocardial infarction has been reported as a serious morbidity, and coronary artery reconstruction must be performed preventing this complication. Our results also indicate that prevention of kinking of the right coronary artery was associated with an improved prognosis. We believe that the enlarged sinus of Valsalva was replaced by a composite graft, the ostium of the right coronary artery was consequently located distance away from the graft. By reconstructing the right coronary artery in a left posterior and cephalic position, i.e., by traction toward the left shoulder, we can compensate for this misalignment and prevent kinking. Bentall procedure with a prosthetic composite graft has been a gold standard procedure as an aortic root replacement. When appropriate cases are selected, valve-sparing surgery can yield better results. However, peri-operative myocardial infarction has been reported as a serious morbidity. In addition, our present clinical analysis revealed that prevention of kinking of the right coronary artery is associated with an improved long-term prognosis. The technical aspects of coronary artery reconstruction are therefore of paramount importance. In particular, the more likely the right coronary artery is to be misaligned and kinked. The larger the sinus of Valsalva, the more likely the right coronary artery is to be misaligned and kinked. After excision of the enlarged sinus of Valsalva and replacement with an adequate size of prosthetic composite graft, the optimal position for the reattached right coronary button should be altered from the preoperatively deviated position due to the aneurysmal sinus of Valsalva. We believe that reconstructing the right coronary artery in a cephalad position and in a slightly counterclockwise direction by rotating the tip of the right coronary button towards the left shoulder may compensate for potential misalignment and help prevent kinking of the critical branch.","PeriodicalId":17841,"journal":{"name":"Kyobu geka.

These patients consisted of 39 men and 6 women, with a mean age of 72 years. There were 5 patients with aortic dissection and 40 patients with non-dissection, and 6 patients had reoperation. There were 19 concomitant surgeries, including coronary artery bypass grafting, valve surgery, and aortic procedure. The bioprosthetic valves used were Magna EASE in 17 patients, Inspiris in 25 patients, Trifecta in 2 patients, and Avalus in 1 patient. All Valsalva grafts used were J Graft Valsalva.Results: The mean intubation time was 19 hours, and the mean intensive care unit( ICU) stay was 6 days. The number of in-hospital deaths was 3 patients, and the mean length of hospital stay was 18 days. The remote mortality rate was 4( 1 heart failure, 2 lung cancer, and 1 pancreatic cancer). There have been no case of reoperation, structural valve deterioration (SVD), or thromboembolism to date, and the rates of freedom of reoperation, SVD, and thromboembolism were all 100%. The 1-, 3-, 5-, and 7-year survival rates were 91.1%, 86.4%, 83.6%, and 83.6%, respectively.Conclusion: The surgical and long-term outcomes of the bio-Bentall procedure in patients over 65 years of age were stable. In patients who may outlive the bioprosthetic valve life, it is important to perform an appropriate and durable Bentall procedure, including valve-in-valve, prioritizing the future of each patient.","PeriodicalId":17841,"journal":{"name":"Kyobu geka.

To understand the dynamics of the aortic root after reconstruction, the R-R interval on the electrocardiogram was divided into 10 equal parts, and the percentage change in area of the basal ring/Valsalva sinus/sino-tubular junction (STJ) level was calculated to evaluate the extensibility of the aortic root. For the basal ring, changes in ellipticity and circumference were also compared.Results: Basal ring, Valsalva sinus, and STJ area changes with cardiac cycle were similar to those in the control group. Basal ring showed a regular circle in systole and an oval in diastole, and its circumference was enlarged in systole.Conclusions: The use of 4D-CT made it possible to evaluate the extensibility of the aortic root after remodeling procedure. In particular, the mobility of the basal ring is large, suggesting that it guarantees the physiological opening and closing of the valve and contributes to its durability.","PeriodicalId":17841,"journal":{"name":"Kyobu geka.

Emergency surgery was performed to stop bleeding and confirm the source of bleeding, and dark red pericardial fluid and hematoma were observed in the pericardial sac. There was no postoperative recurrence of cardiac tamponade. He died 1 year and 2 months after the operation. Case 2:A 77-year-old woman underwent thoracoscopic left upper lobectomy and lymph node dissection for lung cancer. The patient did well until the 6th postoperative day. On the 7th postoperative day, she complained of sudden severe back pain, immediately after which she lost consciousness and went into cardiopulmonary arrest. The echocardiography revealed cardiac tamponade, and emergency pericardiocentesis was performed. The patient died without circulatory improvement despite drainage of approximately 200 ml of bloody pericardial fluid. The pathological findings of autopsy revealed penetrating atherosclerotic ulcer at the descending aorta. We speculated that severe back pain caused the afterload of left ventricle and the increase in left atrial pressure through mitral regurgitation, which might result in a bleeding from the staple-line of superior pulmonary vein in the pericardium.","PeriodicalId":17841,"journal":{"name":"Kyobu geka.
