RESUMO
INTRODUCTION: The presence of symptomatic or asymptomatic intravascular/intracardiac foreign body (FB) is underreported in the literature, but it is more commonly encountered in clinical practice. Nowadays, losing a coronary stent or a guidewire has become a rare event. However, due to the constant increase in the total number of worldwide performed coronary interventions (PCI) and especially due to an increase also in the technical difficulties of these procedures (i.e., new devices+complex techniques), this kind of "lost FB complication" may again become clinically relevant. CASE REPORTS: We report two cases where, during challenging PCIs, 0.014-in. guidewires broke, remaining firmly anchored in the coronary tree floating with their proximal part in the aorta. These wires could have been successfully retrieved with a dedicated three-dimensional snare device, which is specifically manufactured for facilitating this kind of retrieval interventions. CONCLUSIONS: Intracoronary lost guidewires, if untreated, may lead to serious cardiovascular complications, suggesting that one should attempt every possible maneuver to retrieve them from the coronary circulation. By describing the peculiarity of the Entrio snare device, we finally suggest that this kind of dedicated three-dimensional snare device is an excellent tool at cardiologists' disposal for retrieving intracardiac and intravascular lost wires.
