2-Year Outcomes for Transcatheter Repair in Patients With Mitral Regurgitation From the CLASP Study

ObjectivesThis study reports 2-year outcomes from the multicenter, prospective, single-arm CLASP study with functional mitral regurgitation (FMR) and degenerative MR (DMR) analysis.BackgroundTranscatheter repair is a favorable option to treat MR. Long-term prognostic impact of the PASCAL transcatheter valve repair system in patients with clinically significant MR remains to be established.MethodsPatients had clinically significant MR ≥3+ as evaluated by the echocardiographic core laboratory and were deemed candidates for transcatheter repair by the heart team. Assessments were performed by clinical events committee to 1 year (site-reported thereafter) and core laboratory to 2 years.ResultsA total of 124 patients (69% FMR, 31% DMR) were enrolled with a mean age of 75 years, 56% were male, 60% were New York Heart Association functional class III to IVa, and 100% had MR ≥3+. At 2 years, Kaplan-Meier estimates showed 80% survival (72% FMR, 94% DMR) and 84% freedom from heart failure (HF) hospitalization (78% FMR, 97% DMR), with 85% reduction in annualized HF hospitalization rate (81% FMR, 98% DMR). MR ≤1+ was achieved in 78% of patients (84% FMR, 71% DMR) and MR ≤2+ was achieved in 97% (95% FMR, 100% DMR) (all p < 0.001). Left ventricular end-diastolic volume decreased by 33 ml (p < 0.001); 93% of patients were in New York Heart Association functional class I to II (p < 0.001).ConclusionsThe PASCAL repair system demonstrated sustained favorable outcomes at 2 years in FMR and DMR patients. Results showed high survival and freedom from HF rehospitalization rates with a significantly reduced annualized HF hospitalization rate. Durable MR reduction was achieved with evidence of left ventricular reverse remodeling and significant improvement in functional status. The CLASP IID/IIF randomized pivotal trial is ongoing.     

单侧椎弓根螺钉固定TLIF术治疗老年退行性腰椎滑脱的疗效分析

目的 回顾性评价单侧椎弓根螺钉固定经椎间孔椎体间融合(transforaminal lumbar interbody fusion,TLIF)术或合并对侧经椎板关节突螺钉(translaminar facet screw,TLFS)治疗老年患者退行性腰椎滑脱中期随访的临床效果.方法 2009年1月至2012年6月,收集65岁及以上罹患腰椎退行性滑脱伴腰椎管狭窄的患者29例,男性11例,女性18例;年龄65～ 81岁,平均(73.1±6.1)岁;其中单节段患者16例,双节段患者13例;平均随访时间为39.4±9.8个月(24 ～ 54月).单节段患者采用旁正中入路行单侧椎弓根螺钉固定TLIF术,双节段患者在进行单侧双节段椎弓根置钉固定TLIF术后合并对侧TLFS术.记录手术时间、出血量、住院时间及相关并发症;评价手术前后ODI、VAS及JOA评分;使用X线摄片及三维CT评价节段融合情况及矢状位队列情况.结果 平均手术时间为99.5±32.3 min(单节段86.3±25.5 min,双节段115.8±32.4 min),平均住院为12.9±3.7d(单节段12.8 ±2.0d,双节段13.1±5.1d),平均出血量为210.3±181.0 mL(单节段195.0±192.0 mL,双节段229.2±164.5 mL),并发症发生率为10.3％,24个月时滑脱节段融合率为89.7％.术后ODI、VAS及JOA评分改变较术前有统计学差异,术后腰椎前凸角及滑脱节段前凸角较术前增加(32.0±13.8)°vs (36.5±11.6)°;(4.9±5.5)°vs(6.5±4.4)°,差异有统计学意义;但相关前凸角及其改变与临床各评分及其改变无明确相关性.结论 单侧椎弓根螺钉固定TLIF术治疗老年单节段腰椎退行性滑脱安全有效,并发症低;在此基础上合并使用对侧TLFS术治疗老年双节段腰椎退行性滑脱患者,效果同样良好.     

Percutaneous Mitral Valve Replacement Using a Transvenous,Transseptal Approach: Transvenous Mitral Valve Replacement

ObjectivesThe aim of this paper is to describe the feasibility of a novel transcatheter approach for mitral valve replacement using only venous access.BackgroundFailure of mitral valve prostheses necessitating reoperation can represent a high-risk clinical scenario. Although repeat cardiac surgery remains the standard of care for most failed mitral valve operations, nascent transcatheter options are under development for patients at high or extremely risk of surgery. Most often, this is performed via a transapical approach in the operating room, with associated risk of complications as well as extended length of hospital stay.MethodsWe describe a case series of 4 consecutive patients at high risk of reoperation with degenerative mitral prostheses (bioprosthetic valves or rings) who successfully underwent transvenous, transseptal mitral valve replacement with a commercially available transcatheter heart valve.ResultsFrom April to May 2014, 4 consecutive patients underwent transvenous, transseptal mitral valve replacement with a transcatheter heart valve. The mean age was 72 ± 9.9 years, and the average Society of Thoracic Surgeons risk score was 12.5 ± 7.2%. All patients had severe, life-limiting dyspnea. The 4 procedures were successful without intra- or post-procedural complications; echocardiography indicated a well-seated and functioning mitral valve-in-valve or valve-in-ring. Patients were discharged within 2 days after valve replacement with marked improvement in dyspnea.ConclusionsWe describe an innovative technique of transcatheter mitral valve replacement. This case series demonstrates the feasibility of transcatheter mitral valve replacement using only femoral venous access, with a marked reduction in complications and length of hospital stay compared with transapical access or redo surgery.     

Distal patellar tendon avulsion in association with high-energy knee trauma: A case series and review of the literature

Background

Patellar tendon rupture is rare in the general population. Typically, failure occurs proximally or at the mid-substance. Distal avulsion from the tibial tubercle in adults is rare and not well described in the orthopedic literature.

Arthroscopic repair of the meniscal injury using meniscal repair device

Background:

Total meniscus resection after meniscus tear usually leads to faster degeneration and osteoarthritis of the knee joint. Preservation and repair of the injured menisci are therefore of great clinical importance. The aim of this study was to evaluate the clinical effects of arthroscopic repair of meniscal injuries using the Fast-Fix device.

Materials and Methods:

96 patients (58 males, 38 females) with mean age of 24.3 years (range 12–46 years)) with a meniscus injury were treated with the Fast-Fix device under arthroscopy between July 2007 and June 2009. The right and left knees were involved in 46 and 50 patients respectively. In 12, 46 and 38 patients, the injury was located in the anterior horn, body and posterior horn respectively. In 38, 45 and 13 patients, it was in the red, red-white, and white regions, respectively. All-inside and outside-in techniques were used for these meniscal injuries. Criteria for successful surgery were no locking pain or swelling and a negative McMurray test.

Results:

The mean followup period was 3.7 years (range 2–5 years). The surgical success rate was 91.7% (n = 88). The mean Lysholm score increased from 47.8 ± 10.4 preoperatively to 85.7 ± 12.8 postoperatively. The mean Tegner activity score was 7.4 ± 1.6 (range 5–9) preinjury, 2.1 ± 0.9 (range 0–4) preoperatively and 7.2 ± 2.2 (range 4–10) postoperatively (P < 0.001). A total of 92 patients (95.8%) returned to full-time work. The International Knee Documentation Committee score increased from 32.7 ± 10.7 (range 10.3–51.7) preoperatively to 82.5 ± 5.1 (range 65.1–91.2) postoperatively (P < 0.001).

Conclusions:

The Fast-Fix system is an efficient, safe and effective suture technique for meniscal repair.     

Spontaneous delivery through a cervical tear without cervical os dilatation

Spontaneous delivery through a cervical tear, provoked by prostaglandin‐induced uterine contractions, was described in a G2P0 woman with a history of cervical dilatation and uterine curettage. This rare complication with potentially serious maternal–fetal consequences can be predicted by an aberrant cervical response to prostaglandins in parturients with previous cervical interventions.
