Abstract	Over the past 50 years, many researchers have reported heterotopic abdominal heart transplantation in mice and rats, with some variations in the surgical technique. Modifying the transplantation procedure to strengthen the myocardial protection could prolong the ischemia time while preserving the donor's cardiac function. This technique's key points are as follows: transecting the donor's abdominal aorta before harvesting to unload the donor's heart; perfusing the donor's coronary arteries with a cold cardioplegic solution; and topical cooling of the donor's heart during the anastomosis procedure. Consequently, since this procedure prolongs the acceptable ischemia time, beginners can easily perform it and achieve a high success rate. Moreover, a new aortic regurgitation (AR) model was established in this work using a technique different from the existing one, which is created by inserting a catheter from the right carotid artery and puncturing the native aortic valve under continuous echocardiographic guidance. A heterotopic abdominal heart transplantation was performed using the novel AR model. In the protocol, after the donor's heart is harvested, a stiff guidewire is inserted into the donor's brachiocephalic artery and advanced toward the aortic root. The aortic valve is punctured by pushing the guidewire further even after the resistance is felt, thus inducing AR. It is easier to damage the aortic valve using this method than with the procedure described in the conventional AR model. Additionally, this novel AR model does not contribute to the recipient's circulation; therefore, this method is expected to produce a more severe AR model than the conventional procedure.

Abstract	Objectives: To evaluate the influence of prolonged cardiopulmonary resuscitation (CPR) on outcomes in heart transplantation with higher risk donor hearts (HRDHs). Methods: Patients transplanted in our hospital between May 2006 and December 2019 were divided into 2 groups, HRDH recipients and non HRDH recipients. HRDH was defined as meeting at least one of the following criteria: (1) donor left ventricular ejection fraction ≤ 50%, (2) donor-recipient predicted heart mass ratio < 0.8 or > 1.2, (3) donor age ≥ 55 years, (4) ischemic time > 4 h and (5) catecholamine index > 20. Recipients of HRDHs were divided into 3 groups according to the time of CPR (Group1: non-CPR, Group 2: less than 30 min-CPR, and Group 3: longer than 30 min CPR). Results: A total of 125 recipients were enrolled in this study, composing of HRDH recipients (n = 97, 78%) and non HRDH recipients (n = 28, 22%). Overall survival and the rate of freedom from cardiac events at 10 years after heart transplantation were comparable between two groups. Of 97 HRDH recipients, 54 (56%) without CPR, 22 (23%) with CPR < 30 min, and 21 (22%) with CPR ≥ 30 min were identified. One-year survival rates were not significantly different among three groups. The 1-year rate of freedom from cardiac events was not also statistically different, excluding the patients with coronary artery disease found in early postoperative period, which was thought to be donor-transmitted disease. Multivariate logistics regression for cardiac events identified that the CPR duration was not a risk factor even in HRDH-recipients. Conclusion: The CPR duration did not affect the outcomes after heart transplantation in HRDH recipients.

Abstract	Background: Quadricuspid aortic valve is a rare congenital heart disease that may be associated with a different anatomical relationship between the coronary artery ostium and the commissure. Case presentation: Herein, we report a case of a 59-year-old woman who underwent aortic valve replacement for a quadricuspid aortic valve with severe aortic regurgitation. Intraoperatively, the aortic valve had four cusps of almost equal size and the right coronary artery arose adjacent to the commissure between the right coronary cusp and one of the two non-coronary cusps. The annular stitches were placed in a non-everting mattress fashion with pledgets on the ventricular side, and stitches near the right coronary ostium were transitioned to the subannular ventricular myocardium to maintain the distance from the ostium. A one-step smaller-sized prosthesis was selected to avoid an oversized prosthetic valve potentially compressing the right coronary ostium. Conclusions: When performing aortic valve replacement for a quadricuspid aortic valve, careful observation of the coronary location and means to avoid coronary ostium obstruction are essential.

Abstract	A 42-year-old gentleman underwent total aortic arch replacement with Triplex graft (Terumo corporation, Tokyo, Japan) for acute type A dissection. Sixteen months later, a computed tomography revealed a rapidly enlarging low-density area around the graft, with no contrast enhancement. The area was compressing the mediastinal structures, such as the superior vena cava and right pulmonary artery. Suspecting lymphorrhea or perigraft seroma (PGS), surgical drainage was performed. Although fluid accumulation around the graft was cloudy and yellowish, Gram stain was negative. A fatty preparation was administered from the nasogastric tube, demonstrating no leakage of chyle. Intraoperative lymphangiography with indocyanine green also showed no lymphatic leak. Therefore, PGS was suspected. Fibrin glue was applied to the graft and the surgery was completed. PGS drainage after arch replacement, especially with Triplex graft, is extremely rare. We discuss the strategies of diagnosis and treatment for this uncommon complication after aortic surgery.

Abstract	A calcifying fibrous tumor (CFT) is a rare, benign tumor that commonly develops in the internal viscera. It is histologically characterized by hyalinized collagenous tissue with calcifications and lymphoplasmacytic infiltrates. There have been few reports of CFTs occurring in the heart. and the therapeutic approach of such cases has not been well established; however, complete surgical resection appears to be the best treatment option for cardiac CFT, since this lesion can cause cardiac symptoms and recurrence has been recently noted. To our knowledge, this report describes the largest cardiac CFT for which complete surgical resection was successfully performed.

Abstract	Background: A left ventricular assist device (LVAD) is an effective therapeutic option for advanced heart failure. Late right heart failure (LRHF) is a complication after LVAD implantation associated with increasing morbidity and mortality; however, the assessment of right heart function, including right heart reserve function after LVAD implantation, has not been established. We focused on a fluid loading test with right heart catheterization (RHC) to evaluate right heart pre-load reserve function and investigate its impact on LRHF. Methods: Patients aged > 18 who received continuous-flow LVAD between November 2007 and December 2022 at our institution and underwent RHC with saline loading (10ml/kg for 15 min) 1 month after LVAD implantation were included. Results: Overall, 31 LRHF or deaths (RHF group) have occurred in 149 patients. Comparing the RHF and non-RHF groups, pulmonary artery pulsatility index (PAPi) at rest (1.8±0.89 vs. 2.5±1.4, p=0.02) and right ventricular stroke work index (RVSWi) change ratio with saline loading (0.96±0.32 vs. 1.1±0.20, p=0.03) was significantly different. The PAPi at rest and RVSWi change ratio with saline loading were identified as the postoperative risks for LRHF or death. The cohort was divided into three groups based on whether the PAPi at rest and RVSWi change ratio were low. The event-free curve significantly differed between the three groups (p<0.001). Conclusions: Hemodynamic assessment with saline loading can evaluate the right ventricular pre-load reserve function of patients with LVAD. The low RVSWi change with saline loading was a risk factor for LRHF following LVAD implantation.

Abstract	Root infection or dissection involving coronary artery frequently necessitates an emergent Bentall procedure, with low left ventricular ejection fraction (LVEF). In contrast, concerning an elective Bentall for aneurysm, surgeons should balance the risk and benefit of surgery, especially in low LVEF cases. We investigated the association between preoperative LVEF and outcomes after Bentall. We analyzed 98 patients undergoing Bentall between April 2000 and March 2020. The patients were stratified into three groups: (a) 65 with LVEF ≥ 60%, (b) 21 with LVEF 45 to < 60%, and (c) 12 with LVEF < 45%. Baseline characteristics, survivals, and major adverse cardiovascular events (MACE) were compared. To assess potential non-linear relationship between LVEF and mortality, cubic spline analysis was conducted. Median age was similar (a vs b vs c, 52 vs 50 vs 44). In all groups, elective root aneurysm was 50-60%, indicating the rest were complicated and sick. Operative mortality was the highest in group c (4.6% vs 9.5% vs 16.7%, p = 0.294). Survival and MACE-free rate were the worst in group c, though their 10-year survival was 40%. LVEF was an independent risk for mortality, and cubic spline analysis showed potential non-linear association between LVEF and mortality. Although LVEF is an independent predictor of mortality after Bentall, long-term survival was occasionally achieved in low LVEF cases. While surgeons should carefully balance the risk of low LVEF and the benefit of surgery in elective cases, we should perform a non-elective procedure as needed, even if LVEF is low.

Abstract	We report the case of a 47-year-old man who was diagnosed with severe right ventricular outflow tract (RVOT) stenosis due to a space-occupying lesion; the diagnosis was made using computed tomography. He underwent mass reduction, pulmonary valve replacement, and RVOT reconstruction with a bovine pericardial patch. The pathological diagnosis was undifferentiated pleomorphic sarcoma originating from the myocardium. As the mass resection was incomplete, he received heavy particle therapy. He did not want to receive adjuvant chemotherapy. Four months later, severe RVOT stenosis recurred because the residual mass had invaded the prosthetic valve in the pulmonic position and one of the cusps was fixed in the closed position. He presented with dyspnea and marked lower leg edema. We performed superior vena cava (SVC) to right pulmonary artery (RPA) shunting as a palliative operation to improve his heart failure symptoms. After surgery, his symptoms improved; his hemodynamics have been stable for one year. SVC-RPA shunting is a palliative operation but can be used to effectively treat severe RVOT stenosis caused by unresectable cardiac tumors. <
