  Abstract 


Patch degradation after surgical repair of atrial septal defect (ASD) is an uncommon complication. We report a case of surgically repaired ostium secundum ASD that presented with degradation of the patch and a hemodynamically significant shunt, which was subsequently closed by the transcatheter approach.

  Introduction Top


Surgical repair of atrial septal defect is a well-established and highly durable treatment and patch degeneration is rare. We report a case of surgically repaired ostium secundum atrial septal defect that presented with degradation of the patch and a hemodynamically significant shunt, which was subsequently closed by transcatheter approach.


  Case Report Top


A 4-year-old child with a large (22 mm) ostium secundum atrial septal defect (ASD) with deficient posterior and inferior rims [Figure 1]a, right heart dilation, and mild pulmonary hypertension underwent uneventful surgical closure of the defect with a pericardial patch. Postoperative echocardiogram confirmed closure of the defect with no residual shunt [Figure 1]b. On follow-up, 3 months later, she was found to have parasternal heave, wide fixed split S2, and a loud ejection systolic murmur. There was no history of fever in the interim period, no complaint of breathlessness, or other cardiac symptom. The echocardiogram is shown in [Figure 1]c.

Diagnosis

Surgical patch degradation.


  Discussion Top


Surgical repair of ASD is a well-established and highly durable treatment. The pericardium is a suitable material for ASD closure and glutaraldehyde-treated pericardial patches are used to alleviate curling of the edges.[1] However, the postoperative complications may include residual shunt, and uncommonly, patch shrinkage or retraction and degeneration.[2] What differentiated this case from patch dehiscence was that the patch had not given way at the suture line, there was no flap visible and a part of the patch, roughly half the size of the original defect, was missing. Echocardiogram showed a significant left-to-right shunt (10-mm defect), mild right heart dilation, and mild pulmonary hypertension. For a hemodynamically insignificant residual defect, the medical follow-up would suffice.[3] In our case, transcatheter closure of the defect was performed with an 18-mm device [Figure 2]. Postprocedure echocardiogram confirmed good device position [Figure 2]a. The child remained asymptomatic on follow-up.

With the advent of interventional approaches since the 1990s, transcatheter closure with a nitinol occluder device is being increasingly preferred as a minimally invasive approach[3],[4] for ASD closure. As a result, fewer ASD patients are referred for surgical closure and these mainly include patients with large or complex defects. Transcatheter closure of residual postsurgical ASD has been described previously[5] as the preferred approach for residual defects. Residual defects after surgical closure have mainly been attributed to suture dehiscence. Suture dehiscence, may be due to excessive tension, trauma, and kinking stresses at knots,[6] has been associated with primary closure of ASD as opposed to use of a patch,[7] or has been seen in minimally invasive techniques where a limited surgical field may restrict the ability to identify a fractured suture line.[8] In contrast to suture dehiscence, degradation of the pericardial patch after surgery is extremely uncommon, though previously described.[3],[4] Degradation of autologous pericardial valves is more commonly described than ASD patch degradation and may be linked abnormal mechanical shear stresses on the nonpliable leaflets.[9] Risk factors of atherosclerosis such as elevated lipid levels, smoking, or diabetes may play a substantial role in degeneration.[10] Glutaraldehyde treatment of the autologous pericardium also favors degenerative processes and calcification.

In our case, the degradation of the pericardial ASD patch was noted 3 months after surgery. Transcatheter approach was preferred to avoid increased morbidity of reoperation. Although major complications have also been described after transcatheter ASD closure, namely, perforation of the atrial wall, atrial arrhythmias, and device embolization, the rate of such complications is <2%[3] and may be avoided by careful selection of patients.

To summarize, this case illustrates the rare complication of surgical patch degradation and successful percutaneous closure of the resulting defect.
