Primary percutaneous thrombus aspiration alone as definitive intervention for left main coronary artery occlusion presenting as acute anterior wall ST elevation myocardial infarction.

Primary angioplasty and stenting remains the standard of care for patients presenting with acute ST-segment elevation myocardial infarction. Recently, thrombus aspiration has been shown to improve the myocardial perfusion and outcomes in STEMI. In a subset of patients thrombus aspiration may result in optimal perfusion and minimal residual stenosis. These patients may be managed without additional stenting. Three patients with anterior wall STEMI were successfully managed with thrombus aspiration alone without additional stenting. All three are doing well at 30 day follow up with significant improvement in left ventricular ejection fraction.

Outcome of primary PCI - an Indian tertiary care center experience.

OBJECTIVE: To assess the feasibility and outcomes of primary percutaneous coronary intervention (PPCI) for ST-segment elevation myocardial infarction (STEMI) in Indian Scenario. METHODS: Between January 2005 and December 2012, consecutive STEMI patients who underwent PPCI within 12 h of onset of chest pain were prospectively enrolled in a PPCI registry. Patient demographics, risk factors, procedural characteristics, time variables and in-hospital and 30 day major adverse cardiovascular events (MACE) [death, reinfarction, bleeding, urgent coronary artery bypass surgery (CABG) and stroke] were assessed. RESULTS: A total of 672 patients underwent PPCI during this period. The mean age was 52 ± 13.4 years and 583 (86.7%) were males, 275 (40.9%) were hypertensives and 336 (50%) were diabetics. Thirty one (4.6%) patients had cardiogenic shock (CS). Anterior myocardial infarction was diagnosed in 398 (59.2%) patients. The median chest pain onset to hospital arrival time, door-to-balloon time and total ischemic times were 200 (10-720), 65 (20-300), and 275 (55-785) minutes respectively. In-hospital adverse events occurred in 54 (8.0%) patients [death 28 (4.2%), reinfarction 8 (1.2%), major bleeding 9 (1.3%), urgent CABG 4 (0.6%) and stroke 1 (0.14%)]. Nineteen patients with CS died (mortality rate - (61.3%)). At the end of 30 days, 64 (9.5%) patients had MACE [death 35 (5.2%), reinfarction 10 (2.1%), major bleeding 10 (1.5%), urgent CABG 4 (0.6%) and stroke 1 (0.1%)]. CONCLUSION: Our study has shown that PPCI is feasible with good outcomes in Indian scenario. Even though the recommended door-to-balloon time can be achieved, the total ischemic time remained long. CS in the setting of STEMI was associated with poor outcomes.
