Objective

To assess a new aortic anastomotic device for the repair of acute type A aortic dissection (ATAAD) designed to facilitate and expedite ATAAD repair, potentially minimizing the occurrence of distal anastomotic new entry (DANE) and progression of the disease.

Methods

Ten repairs were conducted in an iatrogenically induced ATAAD model using fresh human cadavers and the felt sandwich technique. Five were repaired with conventional 4-0 polypropylene, and 5 were repaired with the new device. With the device, pins were stapled circumferentially through the sandwich and fixed outside with a cap. The sandwich anastomosis was timed. The aortic arch and vascular prosthesis were explanted and connected to a pressure pump filled with glycerol/H₂O solution pressurized at 170/90 mm Hg over 5 minutes. Fluid loss was measured. The anastomoses were checked for DANE, false lumen perfusion (FLP), and dissection progression.

Results

Fifty-four pins (100%) were successfully deployed, with a median of 11 pins (interquartile range [IQR], 10-11.5) per cadaver. Sandwich median time was significantly shorter with the stapler (02:22 [IQR, 01:49-03:05] min/sec vs 06:40 [IQR, 06:23-07:47] min:sec; P = .008). The time for end-to-end anastomosis with the vascular prosthesis (P = .31), as well as measured fluid loss (P = 1.00), were similar in the 2 groups. The suture group showed DANE in 2 specimens, FLP in 3 specimens, and dissection progression in 1 specimen, whereas the stapler group showed none of these conditions. Microscopy showed tearing at stitch channels in all sutured samples and no tears in the stapler group (P = .008).

Conclusions

The new aortic anastomotic device was safe and faster than the conventional technique and may produce more homogeneous and stronger sealing, potentially reducing DANE through less tissue trauma. Further studies in humans are needed to confirm the potential benefits of this novel device.

目的：评估一种用于急性a型主动脉夹层（ATAAD）修复的新型主动脉吻合装置，旨在促进和加速ATAAD修复，潜在地减少远端吻合口新入段（DANE）的发生和疾病的进展。方法：采用新鲜人尸体和毡夹技术对医源性ATAAD模型进行10次修复。5例用常规4-0聚丙烯修复，5例用该装置修复。使用该装置，将销钉周向钉穿夹芯，并用帽固定在夹芯外。定时夹芯吻合。取出主动脉弓和血管假体，连接到压力泵上，泵入甘油/ h2o溶液，加压170/90mmHg，加压5分钟。测量失液量。检查吻合口DANE、假腔灌注（FLP）及夹层进展情况。结果：54个针100%成功部署[平均11 (IQR10-11.5) /具尸体]。使用订书机的三明治中位时间明显缩短[02:22 (01:49-03:05)vs 06:40 (06:23-07:47) min:sec, p=0.008]。与血管假体端到端吻合的时间相似（p=0.31），测量的液体损失（p=1.00）。缝合组2例出现DANE， 3例出现FLP， 1例出现夹层进展。订书机组没有上述症状。镜检显示所有缝合标本的缝合通道均有撕裂，订书机组无撕裂（p=0.008）。结论：该装置比传统技术安全、快速，可产生更均匀、更强的密封，可能通过减少组织损伤来减少DANE。需要进一步的人体研究来证实这种新设备的潜在益处。

Objective

Our study aims to compare the long-term survival and clinical outcomes of ring and band prostheses for annuloplasty repair of functional mitral regurgitation.

Methods

From March 2005 to November 2017, 160 patients with moderate to severe functional mitral regurgitation underwent undersized annuloplasty using semirigid complete ring (N = 69) or partial band (N = 91) prostheses of the same material and manufacturer. Primary outcomes were long-term survival and clinical outcomes, and secondary outcomes included comparison of postoperative echocardiography data.

Results

Both groups had comparable baseline characteristics, cardiac function, functional mitral regurgitation severity, and perioperative complications. Complete ring and partial band groups experienced equivalent 10-year freedom from cardiovascular mortality (65.2% vs 68.3%, P = .39) and functional mitral regurgitation recurrence (78.5% vs 71.4%, P = .27). At a mean follow-up of 58 ± 46 months, both groups had a parallel increase in ejection fraction (+7% ± 16% vs +5% ± 15%, P = .35) and reduction of left ventricle internal diameter end-diastole (−0.5 ± 0.8 cm vs −0.4 ± 0.9 cm, P = .61). The complete ring group had greater reduction in left ventricle internal diameter end-systole (−0.6 ± 0.9 cm vs −0.2 ± 0.9 cm, P = .007) but higher mean (5.6 ± 3.4 mm Hg vs 5.0 ± 7 mm Hg, P = .025) and peak (16.7 ± 19.4 mm Hg vs 12.9 ± 10.7 mm Hg, P = .048) transvalvular pressure gradients. Mean transvalvular pressure gradient predicted postoperative mortality at 10 years (hazard ratio, 1.19; 95% CI, 1.0037-1.357; P = .013).

Conclusions

Complete ring and partial band annuloplasty for functional mitral regurgitation confer equivalent 10-year survival and mitral regurgitation recurrence. Complete ring repair was associated with increased left ventricle reverse remodeling yet higher long-term valvular gradients.

Objective

Celsior solution (CS) (IGL Group) is used for cold preservation of hearts from brain death donors but not for those from circulatory death donors (DCD). Plasma membrane repair proteins are crucial for maintaining myocardial integrity during ischemia. We compared the effects of CS cold preservation with normal saline (NS) on myocardial membrane disruption and pyroptosis in human DCD hearts, with varying warm ischemia times (WIT) and cold storage durations.

Methods

Twenty-four human DCD hearts (WIT ≤30 minutes [n = 12] and WIT >30 minutes [n = 12]) were procured and divided into 4 groups based on preservation solutions and WIT (n = 6 per group): NS + WIT ≤30 minutes, CS + WIT ≤30 minutes, NS + WIT >30 minutes, and CS + WIT >30 minutes. All hearts received del Nido cardioplegia before cold storage in CS (n = 12) or NS (n = 12) for 6 hours. Left ventricle biopsies were performed at 0, 2, 4, and 6 hours to assess myocardial membrane proteins (annexin A1, dysferlin, and mitsugumin 53), calcium levels, pyroptotic proteins (NACHT, LRR, and PYD domains-containing protein 3 and gasdermin D, N-terminal fragment), edema, and injury scores.

Results

Before cold storage, DCD hearts with a WIT >30 minutes showed impaired membrane integrity, increased pyroptosis, calcium overload, significant edema, and injury. After cold storage, neither normal saline nor CS improved myocardial integrity in hearts with a WIT >30 minutes. However, cold CS storage did help preserve myocardial membrane integrity and reduce pyroptosis, edema, and injury for up to 4 hours in hearts with a WIT of 30 minutes or less.

Conclusions

CS effectively preserves DCD hearts with WIT ≤30 minutes for up to 4 hours, highlighting its potential in optimizing DCD heart preservation.

目的：冻干液（CS）用于脑死亡供者的心脏冷保存，但不适用于循环死亡供者的心脏冷保存。质膜修复蛋白在缺血时维持心肌完整性至关重要。我们比较了CS冷保存与生理盐水（NS）在不同热缺血时间（WIT）和冷保存时间下对人DCD心脏心肌膜破坏和焦亡的影响。方法：取24颗人DCD心脏（WIT≤30,n=12, WIT bbb30, n=12），根据保存溶液和WIT分为4组（n=6/组）：(i) NS+WIT≤30分钟（min），（ii） CS+WIT≤30分钟，（iii） NS+WIT>30分钟，（iv） CS+WIT>30分钟。所有心脏在冷藏前均接受del Nido心脏骤停，对照组（n=12）或对照组（n=12）保存6小时。在0、2、4和6小时进行左心室活检，以评估心肌膜蛋白（膜联蛋白A1、Dysferlin和MG53）、钙水平、焦亡蛋白（NLRP3、GSDMD-NT）、水肿和损伤评分。结果：在冷藏前，体外循环30分钟的DCD心脏表现出膜完整性受损、焦亡增加、钙超载、明显水肿和损伤。冷藏后，生理盐水和低温均不能改善心肌完整性。然而，低温低温储存确实有助于保持心肌膜的完整性，减少心肌坏死、水肿和损伤，并在心肌缺血30分钟或更短时间内保存长达4小时。结论：Celsior可有效保存WIT≤30 min的DCD心脏长达4小时，突出了其优化DCD心脏保存的潜力。
