Right Ventricular Function Predicts Outcomes After PMVR www.physiciansweekly.com April 21, 2025, 8:15 a.m.
Mitral regurgitation (MR) is a prevalent valvular heart condition often associated with poor clinical outcomes, especially when left untreated or inadequately managed. While percutaneous mitral valve repair (PMVR) with the MitraClip system, in conjunction with guideline-directed medical therapy, has demonstrated clinical and prognostic benefits in select patients with symptomatic severe MR, a considerable proportion of individuals continue to experience major adverse cardiovascular events (MACE)—including death or heart failure-related hospitalizations, within the first year following the procedure. Consequently, early identification of patients who are unlikely to respond favorably remains a critical clinical goal.

3D printing of heart valves www.cell.com March 22, 2025, 11:15 a.m.
The manufacture of artificial heart valves is very challenging owing to their stringent functional requirements. The latest advances in 3D printing technologies hold great promise to revolutionise the manufacture of artificial heart valves. Recent 3D printing innovations go far beyond the fabrication of anatomical moulds, and unlock unprecedented opportunities to manufacture exquisite architectures, hierarchical bioprinting of cells, complex multi-material assembly, and the creation of biomimetic structures. This provides new avenues to enhance the functionality of artificial heart valves with respect to hydrodynamics, durability, biocompatibility, and the ability to be implanted via a minimally invasive transcatheter procedure.
Multimaterial cryogenic printing of three-dimensional soft hydrogel machines www.nature.com March 22, 2025, 11:13 a.m.
Hydrogel-based soft machines are promising in diverse applications, such as biomedical electronics and soft robotics. However, current fabrication techniques generally struggle to construct multimaterial three-dimensional hydrogel architectures for soft machines and robots, owing to the inherent hydrogel softness from the low-density polymer network nature. Herein, we present a multimaterial cryogenic printing (MCP) technique that can fabricate sophisticated soft hydrogel machines with accurate yet complex architectures and robust multimaterial interfaces.
Formulation and Evaluation of PVA/Gelatin/Carrageenan Inks for 3D Printing and Development of Tissue-Engineered Heart Valves advanced.onlinelibrary.wiley.com March 22, 2025, 11:09 a.m.
Congenital and acquired valvular heart diseases (VHDs) are significant causes of mortality worldwide. With valve replacement being the primary solution for VHD, current options display shortcomings, including calcification, thrombogenicity, and hemodynamic alteration, leading to repetitive surgeries. Tissue engineering, however, has shown great potential for fabricating heart valves (HVs) with fewer complications. Here, a series of inks are developed, combining poly(vinyl alcohol), gelatin, and carrageenan for 3D printing of tissue-engineered heart valves (TEHVs). The inks/hydrogels are investigated to characterize their physico-chemical, morphological, mechanical, and rheological characteristics. In vitro and in vivo biocompatibility, immune response, hemolysis, and thrombogenicity of the inks/hydrogels are also evaluated.

Cor triatriatum dexter in Dogs: A Silent Bystander or a Potential Time Bomb? www.mdpi.com Feb. 17, 2025, 11:10 a.m.
Cor triatriatum dexter (CTD) is an uncommon congenital anomaly consequent to an abnormal separation of the atrium during embryological development, determining the persistence of the fibromuscular membrane dividing the right atrium. Based on the severity of the obstruction determined by the membrane, the clinical signs may be silent or appear as heart failure, with consequent ascites, and if there are other associated congenital cardiac anomalies, they could manifest as cyanosis or sudden death. The aim of the present review is to give a professional perspective, considering the defect from different points of view.
Making Heart Valves in Minutes mp.weixin.qq.com Feb. 13, 2025, 9:16 a.m.
Researchers at Harvard University have developed a technique that can make a biomaterial heart valve in minutes. The method is called “Focused Rotary Jet Spinning,” and the researchers describe it as “a marshmallow machine with a hairdryer at the back.” Basically, this technique uses air spray to direct the polymer fibers to a heart valve-shaped frame. This forms a porous scaffold that allows heart cells to enter and grow. These formed structures also have mechanical properties that serve as unidirectional valves within the heart. These scaffolds contain nanoscale signals that stimulate cell entry and proliferation, with the ultimate goal of gradually replacing biological material scaffolds by cells to achieve heart valve regeneration.

PCR London Valves 2024: Live cases at cardiology conferences “do not compromise patient safety” cardiovascularnews.com Dec. 7, 2024, 6:03 a.m.
Whether the educational opportunity that is afforded by a live case justifies any potential safety risk to the patient continues to be a source of debate, Allen said, prompting the analysis looking at procedural safety among 115 live cases. Their researched comprised transcatheter aortic valve implantation (TAVI) and mitral and tricuspid procedures from three high-volume centres over a 14-year period. Researchers compared safety outcomes from the live cases to corresponding clinical trials and real-world daily practice.
Asymptomatic severe degenerative mitral regurgitation heart.bmj.com Nov. 11, 2024, 10:22 a.m.
Degenerative mitral valve disease is common. Up to a quarter of patients with degenerative mitral valve disease may be asymptomatic despite having severe valve regurgitation. Current guideline indications for intervention in asymptomatic patient are centred on left ventricular dimensions and ejection fraction and may include consideration in atrial fibrillation, pulmonary hypertension and those with left atrial dilatation. However, despite intervention according to these recommendations, patients remain at risk of post-operative heart failure and mortality.
Mitral valve repair with resection and non-resection techniques in Barlow's disease www.sciencedirect.com Oct. 27, 2024, 7:37 p.m.
Increasing adoption of non-resection valve repair in Barlow's disease has been observed in recent years. At mid-term follow-up, the clinical and echocardiographic results of MV repair for Barlow's disease were very good with low risk of mitral valve reintervention. At this time point, the results of non-resection techniques were comparable to the “gold standard” resection techniques. Monitoring of the long-term performance of non-resection techniques is warranted before definitive conclusion can be drawn.
