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 summarize the results of surgical treatment for 79 patients with coarctation of the aorta (CoA) combined with complex anomalies (CA) in recent years.MethodsThe data from 79 patients with CoA combined with CA admitted to Guangzhou Women and Children's Medical Center between January 19, 2010 and September 7, 2017 were collected and analyzed. There were 52 males and 27 females. The median age was 71 days, and the median weight was 4.3 kg. There were 26 patients combined with tracheostenosis and 7 patients with preoperative tracheal intubation. Extended end-to-side anastomosis was used to correct the CoA, and the associated cardiac abnormalities were treated simultaneously by an incision through median sternotomy. All operations were performed by the same group of surgeons.ResultsThe median deep hypothermic circulatory arrest was 18 (13-28) minutes, the median aorta cross-clamp time was 62 (15-199) minutes, the median cardiopulmonary bypass time was 145 (71-674) minutes, the median ventilation time was 72 (9-960) hours, the median length of ICU stay was 144 (12-1 944) hours, and the median length of hospital stay was 24 (2-93) days. Early death occurred in 9 patients and late death occurred in 5 patients. Reoperation occurred in 28 patients and recoarctation developed in 10 patients. After operation, transcoarctation gradient was reduced, and the transcutaneous oxygen saturation, C-reactive protein (CRP), lactate and creatinine were increased. Compared to the survival group, both preoperative and postoperative transcutaneous oxygen saturation were worse and the postoperative levels of plasma brain natriuretic peptide (BNP) and CRP were higher in the death group.ConclusionCorrecting the CoA and the associated CA simultaneously with extended end-to-side anastomosis by an incision through median sternotomy is effective and safe, and the outcomes of immediate and medial-term are satisfactory. Improving oxygenation and limiting elevation of BNP and CRP levels may reduce the death rate.
