Percutaneous repair of inadvertent subclavian artery cannulation： a case report

Although catheterization of the subclavian vein is a common procedure, it might be associated with life-threatening complications including accidental cannulation of subclavian artery. Rash sheath removal could result in fatal hemorrhage. We report a case of inadvertent 6F sheath cannulation of the right subclavian artery during a radiofrequency catheter ablation procedure and successful repair of the cannulation by Angio-Seal STS plus （St. Jude Medical, St. Paul, MN, US）, a collagen-base vascular closure device.

Percutaneous versus Open Achilles Tendon Repair: A Case-Control Study

Purpose: We investigated whether percutaneous suturing of Achilles tendon ruptures showed better results and superiority in terms of clinical outcomes when compared to open suturing. Methods: We conducted a case-control study. Between 2009 and 2014, we performed surgical revisions of closed acute Achilles tendon ruptures in our hospital in 146 patients, of which 71 patients (2012-2014) received percutaneous suturing using Dresden instruments, and 75 patients (2009-2012) underwent open suturing. After a minimum period of 1 year post surgery, we performed clinical follow-up in 25 patients of each of the groups using the AOFAS hind foot score and the SF-12 questionnaire. Furthermore, we implemented a clinical questionnaire with a reference population of 200 healthy individuals. Results: Mean age in the total population of 146 patients was 47 years (range 21 to 83 years) at the time of surgery. The duration of the surgical procedure with percutaneous suturing was significantly shorter (24 versus 43 minutes, p < 0.0001), the complication rate was significantly lower (2.81% versus 10.7%, p < 0.0001), and the time of hospitalisation was significantly shorter (3 versus 4 days, p < 0.0001) when compared to open suturing. During follow-up, no significant differences between the two groups were observed in terms of descriptive parameters. Furthermore, ultrasound examinations of both follow-up populations did not show any significant difference. From a clinical perspective, the good to very good results achieved with open suturing (as measured with the AOFAS hind foot score and the SF-12 questionnaire) have not been significantly improved with percutaneous suturing. The additional use of a new clinical score (with the reference population) demonstrated good to very good consistency with the established scores. Conclusion: In our population, percutaneous Achilles tendon suturing showed significantly lower complication rates and significantly shorter procedure times when compared to open suturing. However, percutaneous suturing did not show clinical improvements of the good to very good results that were achieved with open suturing (as measured with the AOFAS back foot score and the SF-12 questionnaire). The implementation of a new and simple score for the clinical evaluation of Achilles tendon injuries resulted in good to very good consistency with the established questionnaires and, thus, offered a straightforward and rapid alternative when compared to the more elaborate scores.

One-year outcome of percutaneous mitral valve repair in patients with severe symptomatic mitral valve regurgitation

AIM To investigate one-year outcomes after percutaneous mitral valve repair with Mitra Clip~? in patients with severe mitral regurgitation(MR). METHODS Our study investigated consecutive patients with symptomatic severe MR who underwent Mitra Clip~?implantation at the University Hospital Bergmannsheil from 2012 to 2014. The primary study end-point was all-cause mortality. Secondary end-points were degree of MR and functional status after percutaneous mitral valve repair.RESULTS The study population consisted of 46 consecutive patients(mean logistic Euro SCORE 32% ± 21%). The degree of MR decreased significantly(severe MR before Mitra Clip~? 100% vs after Mitra Clip~? 13%; P < 0.001),and the NYHA functional classes improved(NYHA III/IV before Mitra Clip~? 98% vs after Mitra Clip~? 35%; P < 0.001). The mortality rates 30 d and one year after percutaneous mitral valve repair were 4.3% and 19.5%,respectively. During the follow-up of 473 ± 274 d,11 patients died(90% due to cardiovascular death). A preprocedural plasma B-type natriuretic peptide level > 817 pg/m L was associated with all-cause mortality(hazard ratio,6.074; 95%CI: 1.257-29.239; P = 0.012).CONCLUSION Percutaneous mitral valve repair with Mitra Clip~? has positive effects on hemodynamics and symptoms. Despite the study patients' multiple comorbidities and extremely high operative risk,one-year outcomes after Mitra Clip~? are favorable. Elevated B-type natriuretic peptide levels indicate poorer mid-term survival.

Very large aortic pseudoaneurysm repair using a septal occluder

A 63-year-old man,with previous coronary artery bypass surgery presented with infectious aortitis and a large ascending aorta pseudoaneurysm,causing compression of the left internal mammary graft.Percutaneous intervention with stenting of the graft followed by closure of the pseudoaneurysm using an atrial septal defect occluder was successfully carried out.

Echocardiographic and clinical outcomes of central versus non-central percutaneous edge-toedge repair of degenerative mitral regurgitation

ABSTRACT Objectives We aimed to assess the clinical and echocardiographic results of MitraClip implantation in non-central de- generative mitralregurgitation （dMR） compared to central dMR. Background It is unknown if the use of the MitraClip therapy in non-central dMR is as safe and effective as in central dMR.
