AI Article Synopsis

  • * A 66-year-old man with severe mitral valve regurgitation underwent MVP, where a ruptured chorda led to quadrangular resection and further evaluation through the RC-beating test.
  • * The RC-beating test revealed significant leakage that prompted additional surgical adjustments, ultimately resulting in no residual leakage and confirming the test's effectiveness in detecting mitral valve issues.

Article Abstract

Intraoperative evaluation is important for successful mitral valve plasty (MVP). We performed a saline injection test and a retrograde cardioprotective beating test (RC-beating test) for intraoperative evaluation. The concept of the RC- beating test is evaluation of residual mitral valve regurgitation( MR) under cardiac beating. A 66-year-old man with severe MR underwent MVP. The P3 chorda was ruptured and we performed quadrangular resection. The saline injection test showed trivial regurgitation. We then performed the RC-beating test and it revealed severe leakage from the posterior commissure(PC). Since the PC had a sclerotic change, another quadrangular resection was performed. Moreover,as the anterior leaflet( A3) was slightly elongated, the region was resected in an obtuse-angled triangle shape and repaired by suturing the edges. The final RC-beating test showed no residual leakage. The RC-beating test is useful for detecting residual mitral valve leakage.

Background: A subset of patients with mitral valve prolapse (MVP), a highly heritable condition, experience sudden cardiac arrest (SCA) or sudden cardiac death (SCD). However, the inheritance of phenotypic imaging features of arrhythmic MVP remains unknown.

Methods: We recruited 23 MVP probands, including 9 with SCA/SCD and 14 with frequent/complex ventricular ectopy.

With the emergence of less invasive transcatheter valvular therapies, there remains a limited understanding of the feasibility and durability of these approaches in patients with osteogenesis imperfecta and whether they can offer a suitable alternative to conventional surgery. In this context, and with a focus on mitral repair, we report on a case of mitral transcatheter edge-to-edge repair in a patient with osteogenesis imperfecta and conduct a comprehensive review of the characteristics and outcomes of reported osteogenesis imperfecta cases undergoing surgical or transcatheter mitral repair. Given the high burden of complications of surgery in this population, transcatheter mitral repair could potentially serve as a suitable alternative to conventional surgery in this challenging population.

Transcatheter mitral valve replacement (TMVR) may emerge as a surgical alternative for high-risk patients with severe mitral annular calcification (MAC), yet several questions remain to be addressed. We present the case of a 67-year-old high-risk female patient with severe MAC (MAC score = 8) and mitral stenosis (effective orifice area = 121.3 mm).

Bivalvular infective endocarditis is a clinical presentation that is associated to a greater extent with adverse outcomes. The involvement of the intervalvular mitral-aortic fibrosa is a rare complication associated with high mortality rates, requiring high complexity surgery. We report a case of a young male presenting to the emergency department with bivalvular endocarditis and mitral-aortic intervalvular fibrosa involvement.
