In recent years，West China Hospital of Sichuan University actively participated in medical assistance and rescue in Wenchuan，Yushu and Lushan earthquakes. However，professional roles of cardiovascular surgeons in medical assistance and rescue in earthquakes remain unclear because of the particularity of cardiovascular surgery, which often affects the assembly of medical assistance and rescue teams. Thus，we need to explore the necessity for cardiovascular surgeons to join medical rescue teams within 72 hours after earthquake. In this article，medical rescue work of cardiovascular surgeons within 72 hours after 2008 “5•12” Wenchuan earthquake and 2013 “4•20” Lushan earthquake is analyzed and compared to identify professional roles of cardiovascular surgeons in medical rescue within 72 hours after earthquake. It is necessary for cardiovascular surgeons to join medical rescue teams within 72 hours after earthquake.
Baoxing airborne medical team of West China Hospital participated in the medical rescue in 2013 “4?20”Lushan earthquake. The medical team excellently fulfilled their rescue task for 1 week in the earthquake-struck areas where there was power and communication failure and lack of water and food supply. We found some experiences and problems in airbornemedical team assembly and member selection, which may provide quotable experiences for future disaster assistance and rescue teams.
Surgical treatment of atrial septal defect (ASD) mainly includes occlusion or repair under cardiopulmonary bypass. Surgical treatment of atrial fibrillation includes transcatheter radiofrequency ablation or Maze surgery under cardiopulmonary bypass. There are many treatments for ASD patients combined with atrial fibrillation, but each has its own advantages and disadvantages. We reported an ASD patient combined with atrial fibrillation treated by totally endoscopic "one-stop" radiofrequency ablation and simultaneous transthoracic ASD occlusion of atrial fibrillation, with good postoperative results.
Objective To investigate whether angiotensin converting enzyme (ACE) have significant relation to permanent atrial fibrillation (Af) with mitral valvular diseases. Methods 124 consecutive lone mitral valvular disease patients who need surgery were studied. At baseline, all patients underwent a physical examination, 12lead electrocardiography and echocardiography. The plasma ACE level was measured in all patients by a radioimmunoassay technique. Patients who had permanent Af formed the Af group, and those who still kept sinus rhythm (SR) comprised the SR group. In Af group, patients were separated into two groups by the subgroup of mitral valvular disease ［mitral stenosis(MS) and mitral regurgitation(MR)］, then formed MSAf group and MRAf group. Results Af was diagnosed in 47.58% (59/124) of lone mitral valvular disease patients. Patients who had Af were older (by 6 years) than sinus rhythm patients and more frequently had a history of stroke. Mitral stenosis patients were easy to have Af (60.53% vs. 27.08%，Plt;0.05). The plasma level of ACEwas significantly higher in Af group than that in SR group (72.60 ±22.03 U/L vs. 56.40±17.96 U/L，Plt;0.05). In Af group, the ACE level in MSAf group was higher than that in MRAf group (82.92±18.75 U/L vs. 66.25±21.10 U/L，Plt;0.05). Mitral stenosis patients more frequently had a history of stroke than that of mitral regurgitation patients. Af correlated significantly with the level of ACE (r=0.089, P=0.021) and left atrial dimension (r=0.447, P=0.033). Conclusion We validated and extended the hypothesis that increasing ACE level predicted an increasing risk of Af in mitral valvular diseases. It was expressed significantly in mitral stenosis patients especially.
