Percutaneous Coronary Intervention Under Cover of Left Ventricular Assist Device (Impella 2.5).

ABSTRACT

Impella 2.5 is a temporary left ventricular assist device that is being increasingly used in high risk Percutaneous Coronary intervention (PCI). It reduces the cardiac workload and provides assistance to myocardium and vital organs in states of severe left ventricular dysfunction and cardiogenic shock. We report the first case of successful percutaneous coronary stenting performed in a high risk patient using impella 2.5. A 65-year old diabetic and hypertensive male with a known double vessel coronary artery disease and a reduced left ventricular function (ejection fraction, 20%) was admitted with intractable angina. He was on optimal medical treatment for 2 months. His coronary angiogram done 2 months back had revealed double vessel coronary artery disease (subtotally occluded co-dominant left circumflex and moderate 60% stenosis in left anterior descending artery and a normal co-dominant right coronary artery). He was considered a high risk both for Coronary Artery Bypass Graft (CABG) surgery and PCI due to co-morbidities and reduced left ventricular function. As he had failed a trial of optimal medical therapy and the cardiac surgeon's reluctance for surgery, the patient and his family was counseled for high risk PCI with left ventricular assist device using the impella 2.5.
