Bioprosthetic valves are used in aortic valve replacement to avoid lifelong anticoagulation. Bovine pericardial valves have excellent haemodynamics and equivalent freedom from reoperation compared with a porcine bioprosthesis [ 1]. However, early failure (parastent post-cusp tear) can take place due to mechanical stress. We report an acute structural failure on a Trifecta pericardial valve (St Jude Medical, Inc.) explanted after 34 months from a 71-year old woman.

Department of Heart Disease, Haukeland University Hospital, Jonas Lies vei 65, Bergen, 5021, Norway.
Background: There are several high-risk treatment options for valve failure of a biological full root replacement. When tailoring the best treatment option for the patient, implantation of a rapid deployment valve (RDV) should be considered.
Case Presentation: Six patients presented with aortic regurgitation in a full root Freestyle bioprosthesis.

Background: Acute mitral regurgitation due to papillary muscle rupture is a severe complication of acute myocardial infarction. Transcatheter edge-to-edge repair is emerging as an effective alternative to surgical treatment, with encouraging outcomes. Leaflet adverse events are rare and are associated with relapse of significant mitral regurgitation.

Article Synopsis
- The study aimed to streamline the process of 3D printing patient-specific mitral valves in soft materials, which is typically lengthy and complex.
- Researchers developed a technique using transesophageal echocardiography data and various software tools, focusing on adjusting curing times, model thinness, and lattice structures during printing.
- Results showed that realistic and flexible mitral valves could be printed in 1.5 to 4.5 hours, with optimal modifications leading to better functionality for simulation training purposes.
Rheumatic mitral stenosis is a common rheumatic heart diseases in sub-Saharan Afrleading to increased morbidity and mortality. Percutaneous mitral balloon valvuloplasty is the mainstay of less invasive therapy in those with moderate to severe valve stenosis, being symptomatic despite optimal medical therapy. Though generally save with experienced hand and setup, post procedural complications include development of mitral regurgitation, tear and thrombosis.

Article Synopsis
- Managing horizontal cleavage tears in the medial meniscus is complex, with various nonoperative and surgical treatments available, each having its own pros and cons.
- Existing repair methods have been successful but can lead to issues like recurrent cysts and reduced meniscal volume.
- A new surgical technique using a strip of autologous quadriceps tendon, combined with an all-inside compression suture, is proposed as a solution for young patients, aiming to improve the healing process and address previous treatment limitations.
