主动脉移位术纠治婴幼儿完全性大动脉错位伴室间隔缺损和肺动脉狭窄

目的探讨主动脉移位术纠治完全性大动脉错位伴室间隔缺损和肺动脉狭窄(TGA/VSD/PS)的临床应用。方法2004年8月到2005年7月,采用主动脉移位术连续纠治6例TGA/VSD/PS,其中男5例,女1例;年龄4~24个月,平均(11.33±6.86)个月;体重5.6~11.0kg,平均(8.43±2.19)kg。结果无手术死亡。体外循环转流112~204min,平均(153.83±33.70)min,主动脉阻断73~139min,平均(89.16±18.61)min。术后随访2~12个月。6例病儿活动良好,X线胸片示心影较术前略大,肺血增多;心电图示窦性心律,心脏超声检查示主动脉瓣反流轻微2例,轻度1例。射血分数0.74~0.86,短轴缩短率0.34~0.52。结论当前TGA/VSD/PS普遍采用Rastelli手术,但长期随访发现术后并发症较多,结果尚不理想。主动脉移位术重建左心室流出道和右心室流出道,避免了Rastelli手术后左心室流出道梗阻和心外管道梗阻的并发症。

169例动脉调转手术治疗大动脉转位的早、中期结果

目的 探讨大动脉调转手术(ASO)治疗完全性大动脉转位(TGA)的早、中期结果,分析其随访死亡、术后主动脉瓣反流及肺动脉狭窄的危险因素.方法 2004年1月至2007年12月,169例行动脉调转术病儿入选,其中男129例,女40例,平均年龄(11.7±26.3)个月.病儿分两组:Ⅰ组为室间隔完整组(56例),Ⅱ组为室间隔缺损组(113例).所有术后生存病儿均进行超声随访,平均随访时间(27.7±14.6)个月.危险因素采用Logistic回归模型分析.结果 全组住院死亡19例(11.24%),两组间差异无统计学意义.随着整体治疗水平的提高,住院病死率由2004年的16.67%下降到2007年的3.92%.1、3及5年生存率分别为94.00%、91.33%及91.33%,两组间差异无统计学意义.Logistic回归分析发现,ASO术后随访死亡的危险因素为手术年龄大于6个月;术后主动脉瓣反流的危险因素为合并室间隔缺损、年龄大于6个月、术后新主动脉瓣Z值>1;术后肺动脉狭窄的危险因素为手术年龄小于1个月和肺动脉采用补片成形.结论 ASO手术具有良好的早、中期结果,是治疗完全性大动脉转位的理想术式.TGA病儿应该尽早手术治疗,手术年龄大于6个月是随访死亡及主动脉瓣反流的重要危险因素;新主动脉根部与主动脉远端不匹配是术后主动脉瓣反流的危险因素;病儿的生长发育与肺动脉成形材料无生长特性的矛盾是导致术后肺动脉狭窄的危险因素.

Half-turned truncal switch operation for transposition of great arteries with ventricular septal defect and pulmonary regurgitation

A three-month-old girl weighing 4.2 kg, diagnosed with transposition of the great arteries (TGA) and ventricular septal defect (VSD) was referred to us. She had normal-sized pulmonary annulus and moderate pulmonary regurgitation. Because her pulmonary valve was not suitable for systemic circulation due to valvular incompetence, the half-turned truncal switch operation was selected. The postoperative course was uneventful without left or right ventricular outflow obstructions over a year of follow-up. Our report demonstrated that the TGA and VSD with normal pulmonary annulus is not contraindicated for half-turned truncal switch operation.

What is necessary for improvement of arterial switch operation?

We report long-term results of the arterial switch operation (ASO) and postoperative complications related to operative procedure. Between 1998 and 2007, ASO were performed in 42 patients [transposition of the great arteries (TGA) with intact ventricular septum:21, TGA with ventricular septal defect (VSD):13, Taussig-Bing anomary (TBA):7, and double outlet right ventricle with noncommitted VSD:1]. Hospital death occurred in 1 patient (2.4% mortality rate) due to low cardiac output syndrome (LOS) caused by prolonged aortic clamp, who had TGA with VSD, coactation of aortic arch and right ventricular outflow obstruction. Four patients required re-operation (freedom from re-operation rate was 84.7%). Two had pulmonary stenosis and 1 needed right ventricular outflow tract (RVOT) reconstruction with transannular patch. His pulmonary valve used for previous VSD closure was diminished. The other required muscle resection of RVOT. Five patients presented grade II or more neo-aortic insufficiency and 2 of them were TBA. Both these TBA, rerouting of left ventricular outflow tract (LVOT) to the aorta was challenging, they showed LVOT obstruction postoperatively. One underwent aortic valve plasty and the other had residual VSD closure. None had coronary event or abnormality in coronary arteriography. Selection of surgical procedure should be based on morphologic features in order to improve surgical outcome.     

One stage repair of aortic arch anomalies and intracardiac defects

Between August 1985 and May 1990, 27 neonates and infants underwent combined correction of intracardiac and aortic arch anomalies through a median sternotomy. Coarctation (CoA) was combined with VSD (6), AVSD (2), Taussig-Bing (TB) heart (5), transposition of the great arteries (TGA) (1), TGA + VSD (2), congenitally corrected TGA + VSD (1) and VSD + myxoid stenotic outlet valves (1). Interrupted aortic arch (IAA) was combined with VSD (10) and TB heart (1). Two patients had IAA type B as well as CoA. Age at operation varied from 2 to 243 days with a mean age of 51 days. Twenty patients (70%) were younger than 30 days. One TGA + VSD and all TB hearts had maligned outlet septum and right ventricular outflow tract obstruction (RVOTO). Posterior outlet septum deviation and left ventricular outflow tract obstruction (LVOTO) occurred in 8 patients with malalignment VSD and IAA (7) or CoA (1). Aortic arch reconstruction was performed using extended end-to-end anastomoses. In 3 patients, arch hypoplasia necessitated patch implantation. VSDs were closed through the right atrium unless the anatomy dictated otherwise. One TB heart was reconstructed with a Kawashima procedure. All other TB hearts and all TGAs were corrected with arterial switch operation. Obstructing outlet septum was resected whenever necessary. Follow-up was complete and included echo-Doppler control. Eleven patients had postoperative heart catheterisation. Early mortality was 18.5% (5 patients). Persisting LVOTO or RVOTO was responsible. There was no late mortality. Five patients were reoperated upon: 3 for stenotic anastomoses and 2 for a subaortic membranous stenosis. Successful balloon dilatation of recoarctation was performed four times.(ABSTRACT TRUNCATED AT 250 WORDS)     

Clinical results of arterial switch operation for double-outlet right ventricle with subpulmonary VSD.

OBJECTIVE: An arterial switch operation is considered a good alternative for the repair of double-outlet right ventricle (DORV) with atrioventricular concordance connection and subpulmonary ventricular septal defect (VSD) when intraventricular rerouting is not feasible. The clinical results of an arterial switch operation with ventricular septal defect closure for this anomaly were studied. METHODS: Between 1986 and 1997, 27 patients ranging from 10 days to 5 years of age (mean 0.4 years) underwent an arterial switch operation with ventricular septal defect closure for the correction of double outlet right ventricle with subpulmonary VSD. The 50% rule was used to define double-outlet right ventricle. Arch anomalies were associated in nine cases, and were corrected either previously or simultaneously. A subarterial muscle resection was performed in 14 without any subsequent stenosis of the ventricular outflow tract. The relationship of the great arteries was mostly anteroposterior in 15 and mostly side by side in 12. The left coronary artery (main trunk or circumflex artery) courses behind the pulmonary artery in 15/27 (six/15 in the anteroposterior relation and ten/12 in the side by side relation). The Lecompte maneuver was used to reconstruct the pulmonary artery in all but five cases with a side by side relationship of the great arteries. RESULTS: There was one operative death (3.7%) and three late deaths. The actuarial survival rate was 83 +/- 8% at 9 years. Right ventricular outflow tract obstruction including peripheral pulmonary stenosis developed in seven cases operated on in the early era. The reoperation free rate was 46 +/- 20% at 9 years. CONCLUSION: Although double-outlet right ventricle with subpulmonary VSD has complex features, including an aortic arch obstruction and coronary artery anomalies, an optimal definitive surgical repair using an arterial switch operation can be performed safely with a thorough understanding of this variable anomaly. The prevention of right ventricular outflow tract obstruction at the time of an arterial switch operation may thus help improve the rate of late morbidity.     

Anatomical repair of double outlet right ventricle associated with complete atrioventricular septal defect and pulmonary stenosis: extending the indications for aortic translocation

The combination of double outlet right ventricle (DORV) and complete atrioventricular septal defect (CAVSD) remains a surgical challenge for anatomical repair. Inasmuch as the ventricular septal defect is noncommitted in this combination, the major concern regarding anatomical repair is the reconstruction of the unobstructed left ventricular outflow tract without compromising right ventricular volume and the right ventricular outflow tract. We report on a patient who underwent an anatomical repair using aortic root translocation for DORV with CAVSD and pulmonary stenosis (PS).     

Arterial switch operation with ventricular septal defect repair and aortic arch reconstruction

The arterial switch operation for transposition of the great arteries or double outlet right ventricle with ventricular septal defect (VSD) and aortic arch obstruction is a challenging procedure. One-stage neonatal repair is preferred; however, palliation may be indicated in the newborn who presents with Swiss cheese septum or the patient with extracardiac complications such as necrotizing enterocolitis or subarachnoid hemorrhage. The aortic arch repair is performed with continuous cerebral perfusion and includes patch enlargement of the transverse aortic arch and ascending aorta to control for the important diameter mismatch between the aorta and the pulmonary root. The VSD is no longer closed through the pulmonary valve. Instead, the VSD is approached through the aortic valve after harvesting of the coronary buttons and/or through the tricuspid valve and, if necessary, through an infundibulotomy. The coronary artery transfer is often complex because of the presence of unusual coronary artery patterns and requires precise technique. Subaortic obstruction is often present and requires correction. The right ventricle can be mildly hypoplastic but is not a contraindication to repair unless there is important tricuspid stenosis.     

Intraventricular Tunnel Repair of Double Outlet Right Ventricle

Double outlet right ventricle (DORV) may be divided into subsets according to the position and commitment of the ventricular septal defect (VSD) to the great arteries. In DORV with subaortic VSD, an intraventricular tunnel repair is the recommended operation. The current hospital mortality is 5% with an actuarial survival of 83% at 15 years. DORV with doubly committed VSD should also be repaired with an intraventricular tunnel, and the surgical results are similar to those for DORV and subaortic VSD. In DORV with subpulmonary VSD, an intraventricular tunnel repair is advisable when the distance from the tricuspid to the pulmonary valve exceeds the distance from tricuspid to aortic valve. Otherwise, a spiral intraventricular tunnel or an arterial switch procedure should be considered. In DORV with doubly committed VSD, the results of surgical treatment have been less good, and alternative forms of surgical treatment require further evaluation. The surgical treatment of DORV with pulmonary stenosis and the surgical details of the intraventricular tunnel repair are discussed.     

Arterial switch operation: late results and a future perspective

Intermediate results of the arterial switch operation for variety of cardiac anomaly with the transposed great arteries were studied to elucidate late results and problems. Seventy-five survivors of the arterial switch operation at our institute between 1991 and January 2007 were studied retrospectively. Mean follow-up time was 7.5 years. There were 2 late deaths, 3 reoperations, and 9 cases of catheter intervention, resulting in actuarial survival of 97%, and event-free rate of 83% at 16 years. Seventy patients (93%) were medication free and had no restriction on physical activities. Moderate pulmonary stenosis in 2 patients and mild pulmonary stenosis in 14 were observed. Moderate aortic regurgitation in 2 and mild aortic regurgitation in 20 were observed. Risk factors for right ventricular outflow obstruction were a diagnosis of double outlet right ventricle (DORV), association with aortic arch obstruction, and prior pulmonary artery banding (PAB). Risk factors for branch pulmonary artery stenosis (PS) were not clear; however, scar formation with use of xenograft patch and in-fold formation by redundant autologous pericardial patch for closure of the defects in the old aortic root seemed to be related with the stenosis. Risk factors for aortic regurgitation were age at operation and prior PAB. Early primary arterial switch operation may resolve these problems.
