Absence of rapid deployment extracorporeal membrane oxygenation (ECMO) team does not preclude resuscitation ecmo in pediatric cardiac patients with good results.

We evaluated the results of using extracorporeal membrane oxygenation (ECMO) as resuscitation for cardiac patients undergoing cardiopulmonary resuscitation (CPR) in our setting where neither perfusionists nor surgeons are always on site, and no circuit may be ready. Between 2003 and 2006, we used ECMO for all cardiac patients who underwent cardiac arrest in the pediatric intensive care unit (PICU) or Cath Laboratory. We reviewed retrospectively 14 consecutive files (15 episodes). Mean CPR time before ECMO institution was 44 minutes (10–110 minutes). The surgeons, perfusionist, and scrub nurse, not on site for three of these patients, had to be called in simultaneously with institution of CPR. Two died on ECMO, the third one was successfully transplanted after 5 days. Globally, 10 patients could be weaned (66%). Eight patients (57%) survived to hospital discharge, seven without obvious neurological damage. One patient was bridged to a left ventricular assist device (LVAD) and was eventually successfully transplanted. He had an ischemic brain lesion with good recuperation and no sequel. We obtained good results with resuscitation ECMO in our setting where a permanently on-site rapid deployment ECMO team is not present at all times.

Isolated cleft of the mitral valve: distinctive features and surgical management.

BACKGROUND Controversy remains as to whether isolated cleft of the mitral valve and cleft of the atrioventricular septal defect are different entities. Our objectives were to provide a precise description of isolated cleft of the mitral valve and to clarify its surgical management and outcome. METHODS Patients with surgical repair of isolated cleft of the mitral valve were included. RESULTS Ten patients (9 female) underwent repair at a mean age of 12.1 +/- 10.5 years and mean weight of 32.1 +/- 17.8 kg. Preoperative echocardiography showed mild or less than mild mitral regurgitation in 6 cases and moderate to severe regurgitation in 4. Intraoperative examination confirmed in all cases a cleft dividing the anterior leaflet of an otherwise normal mitral valve. Attachment of the cleft to the ventricular septum by accessory chordae was found in 3 cases whereas preoperative echocardiography found such attachments in 5. Direct suture of the cleft was performed in 9 cases, associated with repair of tricuspid valve straddling (n = 1), subaortic stenosis (n = 1), and ventricular septal defect (n = 1). One patient with thickened clefts edges required an Alfieri-type repair. After a mean follow-up of 4.9 years (range, 1.3 to 11.9), all patients are asymptomatic without significant mitral regurgitation. CONCLUSIONS Echocardiographic description of isolated cleft of the mitral valve is not always as accurate as intraoperative analysis. This is a distinct morphologic entity from the cleft of the left-sided valve of atrioventricular septal defect, and seems associated with a strong female predominance, with various cardiac and extracardiac features. Surgical repair is successful with excellent midterm results.

Complete Atrioventricular Canal Repair Under 1 Year: Rastelli One-Patch Procedure Yields Excellent Long-Term Results

BACKGROUND Considering more recently proposed techniques, we have evaluated our midterm and long-term results of Rastelli one-patch repair in complete atrioventricular canal. METHODS Between 1984 and 2005, 107 patients with a complete atrioventricular canal underwent a Rastelli one-patch procedure. Two groups were identified: 1984 to 1995 and 1995 to 2005 (respectively, 56 and 51 patients). Mean age at surgery was 5.3 +/- 3.4 months; mean weight was 5.5 +/- 3 kg; trisomy 21 was present in 81 patients; complete atrioventricular canal type A was found in 67 patients, type C in 40 patients. There were 12 cases of potentially parachute mitral valve and 14 associated anomalies treated simultaneously (pulmonary obstruction 11, coarctation 3). The coronary sinus was always left on the right side. After functional and anatomic evaluation, the cleft was closed completely in 8 and partially in 29, and was left intact in 70 cases. RESULTS Early survival was 86% +/- 3%. Five patients underwent early reoperation for residual ventricular septal defect (n = 2) and mitral valve repair (n = 3). Nine patients underwent late reoperations with successful repair: subaortic stenosis (n = 4) and mitral valve repair (n = 5). Late survival at 10 and 15 years was 84% +/- 3%. Freedom from reoperation for mitral regurgitation was 94% +/- 3% at 10 years, and 91% +/- 3% at 15 and 20 years. At last follow-up 30 patients had mild and 3 had moderate mitral regurgitation. CONCLUSIONS Rastelli single-patch repair in complete atrioventricular canal is a safe and reproducible technique. Among survivors, freedom from late reoperation for mitral regurgitation is very satisfactory. A properly taught, learned, and transmitted Rastelli one-patch technique compares very well with any other proposed technique.

Extracorporeal Membranous Oxygenation and Left Atrial Decompression: A Fast and Minimally Invasive Approach

Left atrial decompression for patients under extracorporeal membranous oxygenation is sometimes mandatory, but it may be technically difficult. We describe a safe and minimally invasive technique to perform this while placing a small cannula antegradely in the pulmonary artery trunk.

Isolated Left Common Carotid Artery Connected to the Pulmonary Artery Where Was the Arterial Duct

A three-year-old boy was referred for persistent arterial duct. Transthoracic echocardiography showed a right aortic arch and an unusual Doppler flow in the arch vessels and the pulmonary artery. The tomodensitometry showed a right-sided aortic arch, with successive origin of the right common carotid, the right subclavian artery, and an aberrant (lusoria) left subclavian artery. The left common carotid took origin from the pulmonary trunk. During surgery, a fibrous cord independent from the anomaly was identified. An end-to-side anastomosis between the left carotid and the ascending aorta was done and the fibrous cord was divided. Was this fibrous cord a ductal ligament?

Perventricular Closure of Muscular Ventricular Septal Defects in Infants With Echocardiographic Guidance Only

Objective: To report our experience with perventricular closure of muscular (apical) ventricular septal defects (VSDs) in small infants, with echocardiographic guidance only, in a nonhybrid suite. Methods: Eight infants with nine large muscular (apical) VSDs underwent perventricular device closure in a nonhybrid operating room, with transesophageal and epicardial echocardiography guidance, at a mean age and weight of 3.07 (0.3-7.28) months and 3.7 (2.5-6.2) kg, respectively. Five patients had multiple VSDs. Four had associated cardiac defects. Results: Nine Amplatzer muscular VSD devices with a mean size of 10 (4-14) mm were deployed. Seven patients were discharged from the intensive care unit with a mean length of stay of 8.6 days. Four patients had minimal postprocedural residual shunt; no one had a residual shunt at six-month follow-up. Mid-term results are excellent. Conclusion: Perventricular closure is feasible under echocardiographic guidance only in small patients, even without hybrid suite. This may be a good approach for very symptomatic low-weight infants with apical VSD and may also be useful, in any center, at any time, and in any operating room, to treat an associated apical VSD, even unexpected.

Surgical Closure of Persistent Arterial Duct with Minimal Invasive Anterior Thoracotomy: An Alternative Technique

Surgical approach for persistent ductus arteriosus ligation is typically a left lateral thoracotomy opening the pleural-space with left lung retraction. We describe an alternative approach, with a minimally invasive anterior parasternal incision. This is particularly adapted to preterm infants weighing less than 1.5 kg. This approach ensures a good exposure of vessels. We believe that it is safe, reliable and reproducible. The learning curve should not be an issue for surgeons used to manage low weight patients.

Severe aortic valve regurgitation after percutaneous ventricular septal defect closure

Percutaneous closure of ventricular septal defect is now commonly used. We report a rare case, and especially a rare image of aortic leaflet damage caused by percutaneous ventricular septal device.

Right ventricular outflow repair: the aortic autograft technique procures the best late results in the transposition complex

OBJECTIVE After treatment of transposition of the great arteries (TGA), ventricular septal defect (VSD), pulmonary stenosis, or atresia by various surgical procedures, two main problems led to reoperation: RV-PA conduit or connection stenosis and subaortic stenosis. We report here our mid- and long-term experience of a technique described in 1997 using a segment of aortic autograft as a RV-PA conduit. METHODS Between 1993 and 2005, 25 patients with TGA, VSD, PS, or atresia were corrected with a technique using an intra-ventricular rerouting with conal septum resection (as in reconstruction-endo-ventriculaire (REV)) and interposition of tubular segment of autograft aorta between RV and PA without Lecompte maneuver (as in Rastelli), using in some cases an additional monocusp patch. The patients age at correction ranged from 2.5 months to 11 years (mean 2.2 years); seven patients were under 1 year and 13 had a previous shunt procedure. Patients were regularly followed by two-dimensional (2D) annual echocardiogram, occasionally by catheterization and more recently by MNR. RESULTS There was one postoperative death essentially due to RV failure. There was one late death after 15 years. There were 23 long-term survivors with a mean follow-up of 12.8 years. All patients were in class I category and all of them were in sinus rhythm. Three of them needed a reoperation at 4, 5, and 6 years for subaortic stenosis and one of them with abnormal chordae in the left ventricle (LV) outflow, Only one patient needed a reoperation for RV-PA stenosis, 13 years after correction done at age 2.5 months, the autograft tissue not being implied and found normal at histology. Mean RV pressure by echo at last follow-up was 41 mm Hg. Ten patients exhibit a mild-to-moderate pulmonary regurgitation. Freedom from reoperation for RV-PA obstruction is 90% at 10 and 15 years. CONCLUSION Compared with all other techniques (Rastelli, REV, and Nikaidoh) our autograft technique provides the best-reported outcome for RV-PA outflow freedom from reoperation, the aortic segment employed being a living tissue susceptible to growth. However, it remains most often a long-term valveless procedure and does not avoid occasional unexpected LV-AO stenosis.

Surgical treatment of an extracranial carotid artery aneurysm in a child by an arterial autograft

We report a symptomatic aneurysm of the left common carotid artery (LCCA) in a 6-year-old boy. The patient had been diagnosed and treated 3 years earlier for an isolation of the LCCA with a right-sided aortic arch. At the age of 3 years, the LCCA was reimplanted in the ascending aorta. Three years later, the patient developed a voluminous aneurysm of the LCCA complicated by stroke. An arterial graft was used for the carotid reconstruction with good long-term patency and no aneurysm evolution.
