Off-Pump Methacrylate Cement Pulmonary Embolectomy.
Ann Thorac Surg Short Rep
March 2023
Department of Anesthesiology, Yale School of Medicine, New Haven, Connecticut.
Methacrylate is polymer used as a bone cement in orthopedic procedures that can rarely embolize, resulting in atrial perforation and pulmonary artery occlusion. Retrieval of emboli typically requires cardiopulmonary bypass and deep hypothermic circulatory arrest. In this report, we describe the off-pump removal of a massive left pulmonary artery methacrylate embolus using surface ultrasound localization, partial cross-clamping of the main pulmonary artery, and snaring of the of the left pulmonary venous return.

Removal of a foreign body in the pulmonary circulation is typically attempted by an endovascular approach as the first attempt. The pulmonary artery must be occluded either manually or with cardiopulmonary bypass during the procedure. Here, we report a case of video-assisted thoracic surgery to remove a foreign body from the right pulmonary artery under percutaneous balloon artery occlusion.

The mediastinal vasculature can be affected by various etiologies in cancer patients. Both direct and indirect sequela of cancer may result in life-threatening clinical presentations. Tumor growth may cause vessel narrowing and decreased blood flow from either extrinsic mass effect, invasion into the vascular wall, or tumor thrombus within the lumen.

There are limited tools available to predict the long-term prognosis of persons with coronary chronic total occlusions (CTO). A previously-described blood biomarker panel to predict cardiovascular (CV) events was evaluated in patients with CTO. From 1251 patients in the CASABLANCA study, 241 participants with a CTO were followed for an average of 4 years for occurrence of major adverse CV events (MACE, CV death, non-fatal myocardial infarction or stroke) and CV death/heart failure (HF) hospitalization.

Cardiology Department, Reina Sofia University Hospital, Cordoba, Spain.
Background: The therapeutic management of patients with multivessel disease and severe left ventricular dysfunction is complex and controversial.
Aims: The aim of this study was to analyze the clinical outcomes and the changes in left ventricular ejection fraction (LVEF) in patients with severe left ventricular dysfunction and at least one chronic total occlusion (CTO) undergoing percutaneous coronary intervention (PCI) with hemodynamic support provided by Impella.
Methods: Retrospective, multicenter study enrolling patients with severe left ventricular dysfunction and severe coronary artery disease with at least one CTO who required percutaneous mechanical circulatory support with Impella, from January 2019 to December 2023.
