报告手术治疗双腔右心室20例,合并室间隔缺损16例。均在体外循环下成功切除异常肌束,疏通右室梗阻修补合并室缺。认为手术中鉴别诊断对双腔右心室的疗效有决定意义,以右室流出道切口暴露右室操作方便,异常肌束切除应适度,疏通仍不满意者可采取用自体心包补片加宽右室流出道的方法予以解决。 相似文献

We report the case of a neonate with a complex cardiac anomaly that consisted of a double outlet right ventricle, intact ventricular septum, small left ventricle, and pulmonary stenosis who underwent surgical repair with a successful outcome. We have not previously found a case report of a patient with double outlet right ventricle and intact ventricular septum who is still alive and in good health at an intermediate postoperative follow-up. 相似文献

Double-outlet right ventricle (DORV) is a heart malformation that describes an anomalous ventriculoarterial connection which can be associated with considerable variant of associated lesions. When this malformation is present with two ventricles, biventricular repair is feasible in the vast majority of cases. This report describes the surgical techniques for biventricular repair in all forms of encountered DORV, as well as the surgical strategy employed at our institution. Copyright © 2000 by W.B.

We report a 13-month-old male child with anomalous origin of the right pulmonary artery from the ascending aorta and a double outlet right ventricle. Aortic wall was used for elongation of the pulmonary artery and side-to-end connection to the pulmonary trunk. Special emphasis is made on this particular operative technique for strictly laterally originating right pulmonary artery that requires no prosthetic material, avoids extreme stretching, and may enable normal growth potential. 相似文献

Double outlet right ventricle (DORV) with noncommitted ventricular septal defect (VSD) (DORVncVSD) represents the most extreme form of DORV, raising challenging surgical difficulties for biventricular repair. The considerable distance between the VSD and the aorta is primarily because of the very abnormal location of the aorta. The definition of DORVncVSD includes: (1) a VSD distant (greater than aortic diameter) from both arterial valves; (2) both great vessels arising fully from the right ventricle; and (3) a double conus. Double outlet right ventricle with noncommitted ventricular septal defect is a primitive right ventricle, as seen during embryologic development, characterized by the presence of the entire conotruncus from the right ventricle. One surgical technique for repair of DORVncVSD is rerouting of the VSD to the aorta by a long intraventricular tunnel. This technique is limited by the presence of conal tricuspid chordae and by the distance between the tricuspid and pulmonary valves, and is associated with an important risk of subaortic obstruction. Rerouting through the pulmonary artery followed by arterial switch seems a more satisfactory surgical solution. When the VSD is distant from the aorta, it is almost always quite close to the pulmonary artery. Rerouting to the pulmonary artery creates a smaller channel, and its application is not limited by the presence of tricuspid chordae or the tricuspid-to-pulmonary valve distance. However, the arterial switch frequently involves relocating complex coronary arteries. Copyright © 2002 by W.B. Saunders Company 相似文献

To evaluate the development of an anomalous muscle bandle of the right ventricle (RV) and results of surgical intervention, responses of the RV to atrial pacing and the isoproterenol tests were examined in both the pre- and postoperative periods. Although cardiac output did not increase in proportion to the rate of atrial pacing or the dose of isoproterenol, the pressure gradient through the RV increased abnormally from 38 mmHg to 59 mmHg (atrial pacing) and 116 mmHg (isoproterenol). On the other hand, postoperative evaluation showed normal RV responses in these tests. Since the response of the right ventricle to these tolerance tests in patients with DCRV in pre- and postoperative periods has not been well elucidated, a precise evaluation is reported in this paper. 相似文献

Transatrial repair of double-chambered right ventricle 总被引:1,自引:0,他引:1

Double-chambered right ventricles (DCRVCs) traditionally have been repaired via a right ventriculotomy. We describe the cases of 8 children (aged 7 months to 6 years; weight, 6.3 to 21.5 kg), who underwent repair of DCRV via a right atriotomy. Six patients had ventricular septal defects. Peak systolic gradients in the right ventricular outflow tract were 26 to 135 mm Hg. The QP/QS were 1.1 to 2.5. Cardiopulmonary bypass times were 52 to 89 min (mean, 65.5 min) with aortic cross-clamp times of 20 to 56 min (mean, 39 min). Mean intraoperative gradients following repair were 5.8 mm Hg. Three patients had transient postoperative atrioventricular block requiring temporary pacing. Two patients required minimal inotropic support (dopamine, 2.5 to 5 micrograms/kg/min). The children have all been asymptomatic after hospitalization with follow-up times of 5 months to 4.5 years. No patient requires cardiac medications or has significant, persistent dysrhythmias; however, 1 patient required reoperation. Transatrial repair of DCRV allows excellent operative anatomical visualization and should be considered as an alternative to the transventricular approach in patients with this congenital heart defect. 相似文献

Primary repair of pulmonary artery sling with double outlet right ventricle and distal tracheal stenosis 总被引:3,自引:0,他引:3
Oshima Y Yamaguchi M Yoshimura N Ogawa K Nishijima E Tsugawa C 《The Journal of cardiovascular surgery》2002,43(6):849-851
The fate of patients with pulmonary artery sling depends on associated tracheal lesions. Distal tracheal stenosis involving the carina frequently results in lethal obstruction due to secretion or inflammatory edema. Further-more, associated complex cardiac anomalies with excessive pulmonary flow make the situation more complicated. We present a case of successful simultaneous one-stage repair of pulmonary artery sling, double outlet right ventricle and distal tracheal obstruction. Pulmonary artery sling was relieved by relocation of the left pulmonary artery (left pulmonary artery to main pulmonary artery) and a tracheoplasty (resection and end-to-end anastomosis). We advocate early aggressive simultaneous repair of pulmonary artery sling with tracheal stenosis and concomitant repair of intracardiac anomalies whenever possible. 相似文献

Sixty cases of tetanus with a mortality of 46.6 per cent are presented. Prophylactic antitoxin did not prevent tetanus in 5 per cent of the cases. Patients receiving some surgical treatment of the infected wounds were four times as likely to recover as those not receiving any surgical care. The immediate administration of 50,000 units of antitoxin intravenously and the simultaneous administration of toxoid at five day intervals for two doses would maintain the blood antitoxin level at an adequate level. 相似文献
