BACKGROUND Device complications in complex percutaneous coronary interventions are rare but potentially deadly. Surgical removal is often required. However, an evaluation of surgical therapy beyond case reports is practically not existent. METHODS We prospectively followed all cases of retained guide wires and/or other devices referred to us for surgical removal between 2015 and 2019 and retrospectively searched our database for such cases between 2010 and 2014. RESULTS From 2015 on, eight cases were referred for surgical removal from six different cardiology departments. In the 5 years before, there was not a single case. Six patients were operated emergently. Patients were 60.5 ± 5.42 years old, overweight (body mass index 30.1 ± 3.77) and except for one case (left ventricular-assist device) showed preserved ejection fraction (EF) (mean EF 57 ± 18.01). The retained devices were mostly located in the right coronary artery (50%), followed by the circumflex artery (37.5%) and diagonal branch (12.5%). The devices were remnants of guide wires (n = 4), balloon catheters (n = 3), and in one case a rotablator. Full sternotomy was performed in six patients and two received a left-sided minithoracotomy (n = 2). The operations were performed on-pump in five (62.5%) and off-pump in three patients. Complete extraction of the foreign bodies was possible in all patients. Two patients died; one in unrelated multiorgan failure and one due to retained-device-related right heart failure. The other patients survived and had uneventful postoperative courses. CONCLUSIONS Retained foreign bodies from cardiac interventions can be completely removed surgically using individualized approaches. There appears to be a trend toward a rising incidence of such interventional complications.
