Abstract:
Objective: To explore the clinical effcacy and short-term survival rate of partial cardiac auto-transplantation for treating the patients with giant left atrium.
Methods: A total of 7 patients with rheumatic heart disease received partial cardiac auto-transplantation in our hospital from 2012-08 to 2013-05 were retrospectively studied. The patients were at the age of (54.9±5.0) years including 3 male, all of them combined with giant left atrium and pre-operative atrial ifbrillation (AF), 6 of them received radio-frequency ablation. All patients were monitored for their baseline condition, operative status, peri-operative mortality and complication occurrence for clinical analysis.
Results: All 7 patients received mitral valve replacement, 5 had aortic valve replacement and 2 had aortic valve-plasty, the mean aortic cross clamp time was (271.7±29.0) min. The average left atrial diameter decreased from (91.7±3.5) mm to (64.8±8.1) mm, left ventricular ejection fraction (LVEF) improved from (38.3±6.5) % to (47.4±6.1) % at discharge, allP<0.05; 4 patients recovered to sinus rhythm and no peri-operative death occurred. The patients were followed-up for (20.7±3.9) months, 1 year post-operational survival rate was 100%, 1 patient died at 17 months after operation and the average left atrial diameter was (56.3±3.4) mm in rest 6 patients at the last examination during follow-up period.
Conclusion: Partial cardiac auto-transplantation may obviously reduce left atrial diameter with good clinical effect in certain patients with giant left atrium.
