Clinical Significance of Greater Implantation Height with SAPIEN 3 Transcatheter Heart Valve.

CONCLUSIONS: Among TAVR patients who received the SAPIEN 3 heart valve, a higher AIH (≥0.85) was not associated with a lower rate of PPM implantation or increased operative mortality. Prior RBBB was the only independent risk factor for new PPM implantation. Long-term follow up is crucial in determining the clinical significance of PPM implantation.

Authors: Liu J, Guan H, Zhou L, Cui Y, Cao W, Wang L Abstract AIM: To determine whether VKORC1 rs9923231, CYP2C9 rs1057910, CYP4F2 rs2108622 and ORM1 rs17650 genotypes contribute to warfarin therapy in patients during initiation and maintenance anticoagulation treatment after heart valve surgery. METHODS: 287 Chinese patients with warfarin treatment more than three month after heart valve replacement operations were enrolled. Blood was collected from each subject for DNA extraction and genotyping. Analyzing the relationship between genotypes and warfarin curative effect. RESULTS: Their mean age was 48.0 &pl...

Authors: Pozzoli A, Taramasso M, Haager P, Miura M, Gülmez G, Lin SI, Gavazzoni M, Rickli H, Maisano F Abstract The Portico™ transcatheter aortic valve implantation (TAVI) system (Abbott Vascular, Santa Clara, CA, USA) was specifically designed to reduce some of the limitations associated with first-generation TAVI devices. Most of the currently available clinical evidence was obtained from randomized studies that compared TAVI to aortic valve replacement using first-generation transcatheter heart valve devices. The aim of this review is to describe the characteristics of the repositionable and retrievab...

Conclusion: The overall long-term clinical outcomes in these predominantly elderly patients undergoing AF ablation concomitantly with bioprosthetic valve replacement were satisfactory; however, AF recurrence was frequent. Older age, a history of prior cardiac surgery, and large LA size were associated with an increased risk of AF recurrence. PMID: 31089442 [PubMed]

This study, a prospective, single-arm observational clinical trial of 133 patients conducted at two clinical sites in Europe, also yielded positive results. There were no events of SVD throughout the study period, Edwards noted. The company also plans to further evaluate the new tissue platform through the RESILIENCE trial, a longer-term study that will follow 250 patients under the age of 65. That study will examine calcification levels, hemodynamic deterioration, and valve failure at years five, seven, nine and 11 as early potential predictors of valve durability.

This article was derived from the meeting's discussions. The Task Force identified the following areas for improvement and clarification: reporting of physical dimensions and characteristics of SHVs determining and labelling of SHV size, in vivo and in vitro testing and reporting of SHV hemodynamic performance and thrombogenicity. Furthermore, a thorough understanding of the regulatory background and the role of the applicable ISO standards, together with close cooperation between all stakeholders (including regulatory and standard-setting bodies), is necessary to improve the current situation. Cardiac surgeons s...

Intraoperative surgical prosthetic heart valve (SHV) choice is a key determinant of successful surgery and positive postoperative outcomes. Currently, many controversies exist around the sizing and labeling of SHVs rendering the comparison of different valves difficult. To explore solutions, an expert Valve Labelling Task Force was jointly initiated by the European Association for Cardio-Thoracic Surgery (EACTS), The Society of Thoracic Surgeons (STS) and the American Association for Thoracic Surgery (AATS).

Early onset prosthetic valve stenosis is an uncommon complication after valve replacement surgery and is often caused by thrombus formation. Frequently it can be diagnosed by echocardiography and managed with optimizing anticoagulation and/or thrombolysis. We review a unique case of early bi-leaflet mechanical heart valve (BMHV) dysfunction where the patient rapidly progressed to cardiogenic shock requiring emergent re-do mitral valve surgery. Intraoperatively, the valve leaflets were found to be almost completely immobile secondary to thrombus formation directly on the hinges of the valve.
