  • Minimally Invasive Mitral Valve Replacement Combined with Atrial Fibrillation Radiofrequency Ablation via Right Minithoracotomy

    ObjectiveTo summarize clinical advantages and outcomes of minimally invasive mitral valve replacement (MVR) combined with atrial fibrillation (AF) radiofrequency ablation via right minithoracotomy. MethodsEight patients with mitral valve disease and AF who received surgical therapy in the First Hospital of China Medical University between October 2009 and October 2012 were included in the study. There were 4 males and 4 females with their age of 34-67 (52.4±17.5) years. All the patients underwent minimally invasive MVR combined with AF radiofrequency ablation via right minithoracotomy. Clinical outcomes were summarized. ResultsThere was no in-hospital death or conversion to conventional sternotomy in this group. Two patients received biological valve replacement and 6 patients received mechanical prosthesis. Operation time was 207.9±18.1 minutes, cardiopulmonary bypass time was 81.7±23.9 minutes, and chest drainage amount was 126.7±34.5 ml. AF recurred in 1 patient on the 3rd postoperative day. All the patients were in sinus rhythm at discharge. These patients were followed up for 18.3±7.4 months. During follow-up, 1 patient had AF recurrence. Seven patients were in NYHA class Ⅰ, and 1 patients was in NYHA class Ⅱ. ConclusionMinimally invasive MVR combined with AF radiofrequency ablation via right minithoracotomy can achieve satisfactory clinical results and esthetic appearance, and is a good choice for patients with mitral valve disease and AF.

  • Mitral Valve Repair for Mitral Bileaflet Prolapse

    ObjectiveTo conclude the outcomes of mitral valve repair for mitral bileaflet prolapse. MethodsWe retrospectively analyzed the clinical data of 14 patients with mitral bileaflet prolapse in our hospital between June 2010 and March 2013. There were 10 males and 4 females with at age of 46.9±12.0 years. We used one technique in 4 patients, two techniques in 9 patients, three techniques in 1 patient. ResultsMean follow-up time was 13.1±7.2 months. There was no perioperative death. No reoperation occurred. No or trace mitral regurgitation (MR) was found in 13 patients.

  • The effect of mild hypothermia on multiple organ dysfunction system post-cardiac surgery: a case control study

    Objective To summarize the effect of mild hypothermia on post-cardiac surgery patients with multiple organ dysfunction system(MODS). Methods We retrospectively analyzed the clinical data of 90 patients with MODS after cardiac surgery under cardiopulmonary bypass(CPB) from May 2010 through June 2014 in our hospital. There were 57 males and 33 females at 61±6 years. The patients were divided into two groups including a NT group (without pre-hypothermia treatment,n=32) and a HT group(with pre-hypothermia treatment,n=58). Results Of the 90 patients, totally 18 patients died, 8 patients (13.8%) in the HT group, 10 patients (31.2%) in the NT group with a statistical difference (P<0.05). In the NT group, 12 patients (37.5%) were treated by intra-aortic balloon pump (IABP), and 9 patients (15.5%) in the HT group with a statistical difference between the two groups (P<0.05). The patients' heart rate (HR) decreased significantly after the application of hypothermia. The HR of difference between the two groups at 36 h was significant (P<0.05). The mean aortic pressure (MAP) in the HT group was lower than that of the NT group significantly at 0 h, because we used sedation and muscular relaxation agent. But the MAP in the HT group was significantly higher than that of the NT group after hypothermia 36 h (P<0.05). In the HT group, pressure of oxygen (PO2), mixed venous oxygen saturation (SvO2), and lactic acid (Lac) were improved significantly compared with those of the NT group significantly (P<0.05). There was no statistical difference in prothrombin time (PT) or activated partial thromboplastin time (APTT) between the two groups (P>0.05). But there was a statistical difference in platelet (PLT) between the two groups at 36 h (P<0.05). The aspartate aminotransferase (AST), alannine aminotransferase (ALT), creatinine (Cr) were improved significantly in the HT group (P<0.05). Conclusion Mild hypothermia can improve the organ function effectively. It can slow the MODS development speed and win the time of protection and further treatment for cells and organs. It is an effective and safety therapeutic technique for MODS after cardiac surgery.

    Objective To investigate the effects and feasibility of regional citrate anticoagulation continuous venous-venous hemodialysis(RCA-CVVHD) in acute hepatic & kidney injury after cardiovascular surgery. Methods Ten patients with acute kidney injury combined with acute hepatic injury after cardiovascular surgery were involved in this study. There were 5 males and 5 females at age of 35-69(58.2±12.7) years. All of them were treated by RCA-CVVHD. Blood samples were collected before treatment, 12 h, 24 h, 48 h, and 72 h after treatment. Results There was no statistical difference between post- and pre-treatment regarding with pH value (7.47±0.12 vs. 7.50±0.06 vs. 7.48±0.04 vs. 7.48±0.03 vs. 7.45±0.05, P>0.05) or BE value (0.91±9.97 mmol/L vs. 2.36±3.92 mmol/L vs. –0.22±3.09 mmol/L vs. 1.87±3.58 mmol/L vs. –1.05±1.12 mmol/L, P>0.05). There was a statistical difference in iCa (1.09±0.09 mmol/L vs. 1.15±0.08 mmol/L vs. 1.17±0.08 mmol/L vs. 1.24±0.09 mmol/L vs. 1.16±0.06 mmol/L), Na+ (149.44±6.84 mmol/L vs. 144.33±3.35 mmol/L vs. 143.13±3.52 mmol/L vs.141.25±5.52 mmol/L vs. 136.71±4.92 mmol/L), and tCa/iCa (2.07±0.11 vs. 2.10±1.12 vs. 2.17±0.69 vs. 2.23±1.05 vs. 2.30±0.11), respectively. Conclusion RCA-CVVHD used in patients with acute hepatic impairment is safe and feasible.
