“…Transcatheter CAF closure can be performed using various devices including detachable coils, 13 Amplatzer vascular plug, 12 Amplatzer duct occluder, 8 detachable balloons, 14 and covered stents, 15 while the vast majority of the fistulas were closed using microcoils. 10,16 -18 Microcoils have made an important contribution to the technique of transcatheter CAF closure.…”

BackgroundTranscatheter closure of coronary artery fistulae (CAF) has emerged as an alternative to surgery, but there are no long‐term outcome results.ObjectiveWe report immediate and long‐term results in 24 patients after transcatheter closure of congen‐ ital CAF.MethodsA total of 24 patients aged 5 to 56 years old with congenital CAF underwent attempted percutaneous transcatheter closure using various devices between November 1998 and August 2008. The immediate closure results and clinical follow‐up were reviewed.ResultsOf the 24 patients, 20 (83.3%) underwent successful transcatheter closure using various devices. An angiogram right after device deployment revealed complete occlusion in 15 patients (75%) and trivial‐ to mild‐ residual flow in 5 patients (25%). Four patients (20%) had transient ST‐T wave changes after the procedure. The left ventricular end‐diastolic volume decreased from 165±31.4 mm3 to 128.6±24.4 mm3 (P = 0.012) 24 hours after procedure, and the cardiothoracic ratio from 0.57±0.02 to 0.53±0.01 (P = 0.003). Follow‐up was 100% complete and ranged from 3 months to 10 years. There were no early or late deaths. All patients were asymptomatic with complete closure of CAF except 1 patient (5%) who had a recurrence of shunt at 6‐month follow‐up, which was re‐closed by percutaneous technique.ConclusionTranscatheter closure of CAF is feasible and safe in anatomically suitable vessels and is a promising alternative to surgery in most patients.

“…Controlled release coils or delivery techniques may widen the spectrum of applicable patients [32]. Small diameter coils can be delivered through 3F microcatheters coaxially placed through a coronary guide catheter [27]. In some large, high flow fistulas, we have found that it may be advantageous to first pass a small catheter and/or guidewire completely through the fistula.…”

Coronary artery fistulas are rare persisting vascular connections from a coronary artery to a cardiac chamber or major central blood vessel. The true incidence is difficult to discern because at least 75% may be asymptomatic and clinically undetectable until an echocardiogram or coronary arteriogram is performed. Small coronary artery fistulas that are not clinically detectable are not clearly associated with significant long term complications. Medium or large fistulas are associated with significant long term problems including angina, arrhythmias, myocardial infarction, endocarditis, and progressive dilation. Treatment options include surgical and catheter approaches to significant fistulas. The long term outlook after fistula closure is not well defined and deserves further study.

“…In that condition, the longer the blind pouch, the greater the risk for this complication [22]. Alternatively, some authors have recommended distal placement of the occlusion site to reduce the likelihood of recanalization [25]. Given the rarity of the condition, and even more rare reporting of long-term outcomes, it is difficult to know what strategy would be associated with more favorable long-term outcomes.…”

“…Distal migration of the embolic device is not uncommon. There has been only one previous report commenting on the use of detachable coils in the management of coronary fistulae [25] using interlocking detachable coils. Even in that series, there was a 23% incidence of distal embolization.…”
