A patient came to me with two giant coronary-right ventricular fistulas.
Cardiac surgeons refused to perform open surgery on the patient due to the high risk.
Interventional methods for fistula closure described in the literature were not suitable. Closure via a vein was impossible because several small holes drained the fistulas from the cavity. Antegrade closure through the artery was also impossible because the coils would have slipped into the dilated vessel.
In another conversation with the patient and imaging doctor Khalikova Gulchachak, the idea was to immobilise the coil with a stent so it would not migrate along the bloodstrea
