Objective To summarize the clinical characteristics of coarctation of the aorta (CoA) associated with intracardiac anomalies in infants. Methods The data from August 2009 to August 2017 of 86 infants who were diagnosed with CoA associated with intracardiac anomalies were analyzed. Preoperative diagnosis, surgical findings and post-operation follow-up were analyzed retrospectively. There were 56 males and 30 females at age of 1–346 (95.1±78.0)d. All the included patients underwent single-stage repair of CoA associated with intracardiac anomalies. Results Mean operative time was 279.0±56.4 min, mean cardiopulmonary bypass time was 162.3±51.0 min, and mean aorta cross-clamp time was 74.7±25.2 min. Mean length of ICU stay and ventilation time was 7.4±4.7 days and 101.1±75.4 hours, respectively. The residual transcoarctation gradient before discharge was lower than pre-operative transcoarctation gradient significantly (42.3±17.7 mm Hg vs. 22.1±9.4 mm Hg, P<0.001), and 7 early deaths were observed after surgery. The mean follow-up time of 79 hospital survivors was 31.0±27.4 months. And no late death was found. Transcoarctation gradient of hospital survivors in the last time follow-up was 21.2±11.0 mm Hg. Transcoarctation gradient of 29 patients was higher than 20 mm Hg. However, only 4 patients with significant clinical symptom of lower limbs retardation were recommended for ballon angioplasty consultant. The cumulative recoarctation-free survival in 2-year follow-up was 69.2%. Conclusions To avoid early second-stage operations, single-stage repair of CoA associated with intracardiac anomalies is effective and safe, and the outcomes of early to mid term follow-up are satisfactory.
ObjectiveTo discuss outcomes of arch reintervention for post-repair recoarctation in children.MethodsFrom 2009 to 2019, 48 patients underwent reintervention for post-repair recoarctation in Shanghai Children’s Medical Center. Of the 48 patients, 22 patients had surgical repair, 25 patients had balloon angioplasty (BA), and 1 patient had a stent implantation. The clinical data were analyzed, and the difference in time-to-event distribution between the surgical group and the BA group was determined by a log-rank test.ResultsThe median age at reintervention was 15.0 months (range, 3.0 months-15.1 years). The median weight at reintervention was 9.8 kg (range, 3.0-58.0 kg). The time to reintervention after initial repair was 12.5 months (range, 2.0 months-7.8 years). One patient (2.1%) died in hospital and 1 patient (2.1%) experienced arrhythmia after surgical repair. One late mortality (2.1%) occurred after surgical reintervention. One patient (2.1%) experienced aortic dissection after BA. No patient died after BA. Freedom from residual coarctation or new recurrences was 66.7%, 61.3%, and 56.9%, respectively, at 1, 2, and 5 years after reintervention. Freedom from residual coarctation or new recurrences was 90.0%, 81.8%, and 70.1%, respectively, at 1, 2, and 5 years after surgical repair. Freedom from residual coarctation or new recurrences was 52.0%, 48.0%, and 48.0%, respectively, at 1, 2, and 5 years after BA. Compared with BA, surgery-based reintervention had a lower incidence of residual coarctation or recurrences (χ2=4.400, P=0.036).ConclusionReintervention for recoarctation has favorable early outcomes. Compared with balloon angioplasty, surgical repair has a more lasting effect in relieving the recoarctation.

Methods From May 1998 to November 2006, 29 patients with CoA -HA were admitted to this institute. Subclavian flap angioplasty was performed in three patients, excision of coarctation and end-to-side anastomoses in six pat ients,and end-to-end anastomoses in the remaining 20 pat ients. Their clinical data were retrospect ively reviewed and the long-term follow -up results obtained through telephone o r letters. Results Three patients died of operations, of whom one died of low cardiac output syndrome, one died of sepsis and one died of multiple organs failure. In two months’to eight years’follow -up , no later death and severe neurological complications were found. Two patients suffered from recurrent coarctation, but had no sense of symptoms and free from re-operation. In all pat ients neither systemic hypertension, nor arterial aneurysm and aortic valve regurgitation were found. Conclusions Mortality of surgical corrections is accepted fo r CoA -HA in infants. Preoperative heart dysfunction and prolonged mechanical ventilation are the high risks of operative death. Recurrent coarctation is the major later comp lication.
Abstract： Objective To investigate the clinical results of offpump anatomic surgical repair for complex coarctation in adults. Methods We retrospectively analyzed the clinical data of 7 patients with complex coarctation who underwent onestage anatomic surgical repair between January 2005 and December 2008 in Fu Wai Hospital. There were 5 males and 2 females with the age ranged from 16 to 41 years, average at 24.4 years. Among all the patients, there were 2 patients of coarctation with hypoplastic aortic arch, 1 of coarctation with aortic arch aneurysm, 3 of coarctation with descending thoracic aortic aneurysm, and 1 of coarctation with B type aortic dissection. All patients were diagnosed by color echocardiography, CT or agnetic resonance imaging（MRI）. All off-pump operations were performed under general anesthesia and ambient temperature. Median sternotomy was performed in 1 patient and left thoracotomy in 6 patients. Aortic arch patching enlargement was performed in 4 patients and descending thoracic aorta replacement in 3 patients (including 1 combined with abdominal aorta replacement and 1 case of Stanford B type aortic dissection, trunk stent was transplanted at the same time). Results There was no hospital mortality or severe surgical complications. Seven patients were followed up for a period ranged from 6 to 49 months with an average time of 20.1 months. No late death or recoarctation occurred. Hoarseness occurred in one patient and presented no improvement during the 11 months follow-up. Conclusion Onestage offpump anatomic surgical repair is safe and feasible in treating adult patients with complex coarctation, and it shows a good immediate and longterm result.
Objective A meta-analysis was performed for a comparison of outcomes between surgery and balloon angioplasty (BA) for native coarctation of the aorta (NCA) in pediatric patients. Methods Electronic databases, including PubMed, EMbase, Medline, Cochrane Library, Weipu Data, Wanfang Data and CNKI were searched systematically for the literature aimed mainly at comparing the therapeutic effects for NCA administrated by surgery and BA. Corresponding data sets were extracted and two reviewers independently assessed the methodological quality. Results Ten studies meeting the inclusion criteria were included, involving a total of 723 subjects. It was observed that compared with BA, surgery was significantly associated with a lower incidence of recoarctation (OR, 0.43; 95%CI, 0.30–0.63; P<0.001), repeat intervention due to recoarctation (OR, 0.40; 95%CI, 0.27–0.61;P<0.001) and lower residual transcoarctation gradient in mid to long term follow up (WMD –0.85; 95%CI, –12.34 to –3.76;P<0.001). Compared with BA, surgery was significantly associated with a longer hospitalization time (WMD, 19.40; 95%CI, 15.82–22.99;P<0.001). Incidence of aneurysm formation (OR, 0.64; 95%CI, 0.26–1.57;P=0.33), complications(OR, 1.77; 95%CI, 0.95–3.28; P=0.07), perioperative mortality (OR, 2.57; 95%CI, 0.87–7.61, P=0.09) and immediate transcoarctation residual gradient (WMD –1.66; 95%CI, –4.23–0.90; P=0.2) were not statistically different between surgery and BA. Conclusions Compared with BA, surgery was significantly associated with a lower incidence of recoarctation, repeat intervention due to re-CoA and residual transcoarctation gradient in mid to long term follow up. On the contrary, BA was significantly associated with a shorter hospitalization time. Incidence of aneurysm formation, perioperative mortality, complications and immediate transcoarctation residual gradient were similar between surgery and BA.
Objective To summarize the experiences of the surgical management for adult patients with aortic coarctation. Methods Clinical data of 40 adult patients diagnosed with aortic coarctation undergoing surgical repair in our center between July 2004 and March 2015 were retrospectively analyzed. There were 28 males and 15 females with a mean age of 26.3±11.0 years (ranging 16-57 years). We evaluated the effect of surgery by the change of pressure gradient between upper limb and lower limb, mechanical ventilation time, and length of ICU stay and hospital stay. Results Forty surgeries were finished successfully. One patient died after surgery. The follow-up ranged from 12 to 36 months. The mean pressure gradient reduced significantly after surgery. There were 6 patients suffering blood hypertension at their discharge, and all of them still need antihypertensive drugs. Conclusion Surgical repair is an effective treatment for adult with aortic coarctation. Extra-anatomic ascending-to-descending aortic bypass and concomitant repair of intracardiac anomalies is safe and effective.
