Abstract : The present paper aims to evaluate immediate and short term complications of trans-catheter aortic valve implantation for four years’ period in Al-Najaf Cardiac Center, Iraq. A 53 patients with symptomatic severe aortic stenosis, mean age of (72.9 ± 5.6) years and (54.72%) males, they had high Society of Thoracic Surgeon (STS) score, Underwent trans-catheter aortic valve implantation procedure in Al-Najaf Cardiac Center from January 2015 to August 2019. The procedure was done under local anesthesia and conscious sedation via femoral approach, using both balloon expandable and self-expandable valves. All patients followed immediately post procedure and during period of hospitalization and thereafter periodically for procedure and valve related complications. Immediate and short term mortality was 5.66%, with majority occurs immediately after procedure due to severe paravalvular leak, rupture annulus and cholesterol embolization. Major vascular complications, moderate-severe paravalvular leak and conduction abnormalities were 5.88%, 15.45% and 37.73% respectively. Permanent pacemaker need for only two patients. We observed increase risk of pericardial effusion with balloon expandable valve (p value=0.019). Occurrence of other complications not significantly differs regarding type of valve. This study showed favorable rate of survival with procedural complication rates similar to international registered results
