Respiratory dependent compression of a venous bypass: therapy by stenting.
Although coronary artery bypass surgery has provided major advances in the treatment of coronary artery disease, narrowing of bypass vessels still constitutes a drawback of this therapy. Although this event is most frequently caused by intraluminal processes, obstruction from external structures is extremely rare. We report such a case in which external bypass compression was provoked by deep inspiration causing typical anginal symptoms. Percutaneous coronary intervention including stent placement provided bypass patency independent from the patient's respiratory phase. Disappearance of symptoms and absence of myocardial ischemia in perfusion scans confirmed successful treatment.
