Inflow occlusion
| Resumo: | Thrombotic complications and infective endocarditis in the right heart induced by pacemaker leads are a rare condition, which treatment has not been well studied yet. I present three case reports in which the Inflow Occlusion (IO) technique was used to remove thrombi in the right atrium, associated to the pacemaker leads. Transesophageal echocardiography is the method of choice for the detection of pacemaker leads intracardiac thrombi or vegetations. The extraction through open surgery with or without cardiopulmonary bypass surgery (CPB) is a safe procedure without serious complications and is recommended when the leads cannot be extracted percutaneously due to large masses attached. Its total extraction is essential for the full recovery of the patient. CPB is the method of choice in complicated cases in which the mass is large and invades the surrounding tissue or if the foreign body is infected. However, in certain circumstances with comorbidities that can complicate CPB, IO is the preferred technique. It is effective for intracardiac procedures of short duration, such as the removal of thrombi or catheters of the right atrial and leads from the right atrium or ventricle. |
