مستخلص: | Objective: We sought to describe the use of the TandemHeart percutaneous left ventricular assist device (PVAD) in a group of high-risk patients undergoing complex cardiovascular procedures. Background: There is a substantial risk of acute decompensation and death in patients with cardiogenic shock or a reduced cardiac reserve undergoing high-risk cardiovascular interventions. The TandemHeart PVAD provides near-total hemodynamic support in this setting. Methods: Thirty-seven high-risk patients underwent placement of the TandemHeart PVAD during 38 separate procedures between April 2007 and April 2009. PVAD insertion was considered emergent if a patient was not expected to survive more than 6 hours without PVAD support. Technical success was defined as successful initiation of the PVAD and completion of the intended interventional procedure. Results: All 37 patients were in cardiogenic shock or undergoing complex coronary and valvular interventions with a high probability of hemodynamic collapse. The mean (+/- standard deviation) patient age was 73 +/- 14 years; 97% were in either NYHA class III-IV heart failure or cardiogenic shock; and the mean EuroSCORE was 11 +/- 3.4. Indications for ventricular assist device placement included critical aortic stenosis (n = 8), severe left main coronary stenosis (n = 18), severe multivessel coronary stenosis (n = 19) and severe cardiomyopathy (n = 23). Four patients were being managed for fulminant myocarditis, ventricular free-wall rupture, flail mitral valve or severe paravalvular leak. Despite their critical status and frequent (82%) need for post-procedure blood transfusion, this complex and high-risk patient population tolerated PVAD-supported intervention well and technical success was achieved in all patients. Seventy-one percent of patients survived to hospital discharge with improved functional status. Most deaths occurred in patients not expected to survive due to their moribund status and multiorgan failure. Conclusion: This experience demonstrates the utility and effectiveness of TandemHeart PVAD support in patients with advanced disease, critical clinical status and limited therapeutic options. |
