BACKGROUND: Aortic valve replacement (AVR) is a safe and effective method in the treatment of aortic valve diseases. This study aimed to increase the understanding on re-treatment of aortic diseases after aortic valve surgery through a retrospective analysis of 47 related cases.
METHODS: Forty-seven patients (38 males and 9 females) with previous aortic valve surgery have received reoperation on aorta from January 2003 to June 2012, and the mean interval time of re-intervention to aortic disease was 6 years ((6.0 ± 3.8) years). The secondary aortic surgery included aortic root replacement (14 cases), ascending aorta replacement (10 cases), aortic root/ascending aorta plus total arch replacement with stented elephant trunk implantation (21 cases), and total thoracoabdominal aorta replacement (2 cases). All these patients have received outpatient re-exams or follow-up by phone calls.
RESULTS: After the initial aortic valve replacement, patients suffered from aortic dissection (25 cases, 53%), ascending aortic aneurysm (12 cases, 26%) or aortic root aneurysm (10 cases, 21%). Diameter in ascending aorta increased (5.2 ± 7.1) mm per year and aortic sinus (3.3 ± 3.1) mm per year. The annual growth value of diameter in ascending aorta was higher in patients with rheumatic heart disease than that in Marfan syndrome (P < 0.05). All 47 patients have received reoperation on aorta. One patient died in operating room because aortic dissection seriously involved right coronary artery. Seven patients had renal insufficiency after operation; neurological complications occurred in 14 patients including 7 patients with stroke and the others with transient brain dysfunction. All patients were followed up, the mean survival time was (97.25 ± 17.63) months, 95% confidence interval was 55.24-73.33 months. Eight cases were died during follow-up and five-year survival rate was 83%.
CONCLUSION: To reduce the aortic adverse events after first aortic valve surgery, it is necessary to actively treat and strictly follow-up patients with previous aortic operation especially patients with Marfan syndrome and rheumatic heart disease.
