Late cardiac perforation following transcatheter atrial septal defect closure

Transcatheter closure of secundum atrial septal defect (ASD) has become an alternative to surgery. We present a patient with hemodynamic collapse secondary to cardiac perforation occurring 6-months after the placement of an Amplatzer Septal Occluder and discuss the utilization/complications of this device.     

Early cardiac perforation after atrial septal defect closure with the Amplatzer septal occluder

We report a case of aortic perforation after transcatheter closure of an atrial septal defect by an Amplatzer septal occluder. During emergency surgery, perforations of the dome of the right atrium and the noncoronary sinus of Valsalva of the aorta were repaired. Atrial septal defect was primarily closed. A short anterosuperior rim should be considered a risk factor for aortic perforation in transcatheter atrial septal defect closure.

Repair of aortic-left atrial fistula following the transcatheter closure of an atrial septal defect

We describe the surgical treatment of an aortic-left atrial fistula that appeared 6 months after the placement of an Amplatzer septal occluder for closure of a large secundum atrial septal defect. Successful repair of the fistula was accomplished by a combined transatrial-transaortic approach similar to that used to repair the rupture of a sinus of Valsalva aneurysm.     

Different approaches for minimally invasive closure of atrial septal defects

Background. To improve the acceptance of cosmetic results after closure of atrial septal defects, anterior or lateral thoracotomies are preferred rather than median sternotomies. Along with the availability of minimally invasive techniques, a further reduction in incision length appeared feasible while preserving thoracic stability.

Methods. Various minimally invasive approaches differing in the type of incision and mode of cannulation have been applied under conditions of normothermic ventricular fibrillation. In technique 1 (n = 5), a right parasternal mini-incision was combined with a central aortic and bicaval cannulation. Technique 2 (n = 2) was composed of an anterior submammary mini-incision with femoral arterial and central bicaval cannulation. To optimize the surgical access, the transincisional cannulation of the superior vena cava was replaced by a percutaneous cervical cannulation (technique 3, n = 17).

Results. Effective atrial septal defect closure assessed by intraoperative echocardiography was achieved in all patients. Central neurologic complications were completely absent. Besides temporary atrial fibrillation in one case, no other cardiac complications occurred. There were no cases with complicated wound healing.

Conclusions. Along with modified cannulation techniques and intraoperative echocardiography, minimally invasive techniques can be safely applied for atrial septal defect closure. Submammary incisions were highly accepted and allowed for adequate surgical exposure.     

Off-pump coronary artery bypass grafting with device closure of atrial septal defect

Patients with coronary artery disease and atrial septal defect may have unique clinical characters. We describe an off-pump combined approach for intraoperative device closure of atrial septal defect during coronary artery bypass grafting.     

Surgical patch closure of atrial septal defects

BACKGROUND: Development of nonsurgical techniques for closure of atrial septal defects (ASD) has prompted reevaluation of current surgical outcomes with an emphasis on less invasive methods. METHODS: This retrospective review is based on a single surgeon's experience between July 1, 1988 and December 21, 2002 with 176 consecutive adult (n = 47) and pediatric (n = 129) surgeries, in which ASD was the primary anatomical diagnosis to ascertain current optimal methods and outcomes expected for surgical closure. Patch closure with pericardium was used in all cases. Surgical methods encompassed three phases. The first phase was defined by traditional sternotomy; the second phase involved a series of technical modifications to shorten incisions and reduce surgical trauma; the third phase consisted of standardized less invasive techniques based upon age and gender with "bikini line" incisions for adult females, limited median sternotomy for adult males, and mini-median sternotomy for children. All patients underwent echocardiography to assess ASD closure. RESULTS: There were no deaths. The most frequent perioperative complications were atrial fibrillation (adult 10%, pediatric 1.2%) and post pericardiotomy syndrome (adult 2%, pediatric 4.7%). All patients had secure and complete closure of ASDs with no residual shunts (trivial or otherwise) documented by echocardiography. No less invasive procedures required conversion. CONCLUSIONS: Surgical technique evolved from standard sternotomy to limited access incisions using modified cannulation techniques and incision locations determined by age and gender of the patient without deterioration in outcome quality. Both standard and less invasive surgical methods can achieve secure closure of the septum with biological patches, which are incorporated into the tissue structure of the heart and which are free from materials-related failure modes. Patient satisfaction is enhanced by utilizing the least invasive, least traumatic, and most cosmetically appealing techniques for access and cardiopulmonary bypass.     

Surgical closure of atrial septal defect

Background: Closure of ostium secundum atrial septal defect (ASD) vis median sternotomy (MS) is a simple procedure for most cardiac surgeons. Minimally invasive cardiac surgery (MICS) has recently been applied in the management of intracardiac lesions. Methods: We report our experience in surgical closure of isolated ASD via MICS in 60 patients and via MS in 58 patients. There was no difference between these two groups in gender, age, body weight, ratio of systemic to pulmonary blood flow, and pulmonary arterial pressure. Results: The duration of cardiopulmonary bypass was significantly longer in the MICS group than in the MS group [27 to 126 min (42 ± 12) and 14 to 158 min (27 ± 11), respectively; (p < 0.001]. However, the length of incision, incidence of temporary pacemaker wire insertion rate, duration of endotracheal intubation, timing of oral intake, postoperative day drainage amount, incidence of parenteral analgesic injection, postoperative length of stay, and return to normal activity interval were significant shorter and lower in patients of the MICS group than in those of the MS group. All the patients recovered rapidly from the surgery. Follow-up was complete in all patients, with no late complications and no residual shunt. Conclusion: Our results suggest that MICS is a good option for surgical closure of ASD. Received: 4 June 1997/Accepted: 29 October 1997
