Prevalence of Guideline Discordant Aspirin use and Associated Adverse Events in Patients on Warfarin for Mechanical Valve Replacement
Antithrombotic therapy guidelines change over time due to evolving research and available treatments. For concomitant aspirin in patients on vitamin K antagonists for ischemic stroke prevention in mechanical heart valves, guidelines have shifted. In 2020, citing the fact that previous studies included many patients with older-generation valve prostheses and acknowledging the increased risk of major bleeding, the American College of Cardiology (ACC) and American Heart Association (AHA) reversed their previous recommendations to routinely add aspirin to VKA therapy.

Prevalence of Guideline-Discordant Aspirin Use and Associated Adverse Events in Patients on Warfarin for Mechanical Valve Replacement
For patients on warfarin for mechanical heart valve replacement, the 2020 American College of Cardiology and American Heart Association Guidelines recommend only adding aspirin in patients with a specific indication for antiplatelet therapy. This contrasts with prior guidelines, which recommended concomitant aspirin therapy. We sought to assess the prevalence of guideline-discordant aspirin use among patients on warfarin for mechanical heart valve replacement and to compare adverse event rates among patients with and without concomitant aspirin.

The “fender” technique for redo-TAVR in a degenerated supra-annular valve with high-risk of coronary obstruction
A 77-year-old woman affected by diabetes mellitus and end-stage kidney disease on dialysis was admitted to our department for congestive heart failure and evidence of structural deterioration (1) of an Acurate Neo S (Boston Scientifics) aortic transcatheter heart valve (THV) implanted 4 years prior. At transthoracic echocardiography, sclerotic degeneration of THV's leaflets with significant increase in valve gradients (mean gradient 45 mmHg, valve area 0.97 cm2) and mild central aortic regurgitation was observed (Figure 1, Panel A-B).

Multicentre, open-label, randomised, controlled trial to compare early intervention with calcimimetics and conventional therapy in preventing coronary artery calcification in patients with secondary hyperparathyroidism (UPCOMING): a study protocol
Introduction Coronary artery and heart valve calcification is a risk factor for cardiovascular death in haemodialysis patients, so calcification prevention should be started as early as possible. Treatment with concomitant calcimimetics and low-dose vitamin D receptor activators (VDRAs) is available, but not enough evidence has been obtained on the efficacy of this regimen, particularly in patients with short dialysis duration. Therefore, this study will evaluate the efficacy and safety of early intervention with upacicalcet, a calcimimetic used to prevent coronary artery calcification in this patient population. Methods ...

Partial Heart Transplantation - How to Change the System
Partial heart transplantation is the first clinically successful approach to deliver growing heart valve implants. To date, 13 clinical partial heart transplants have been performed. However, turning partial heart transplantation into a routine procedure that is available to all children who would benefit from growing heart valve implants poses formidable logistical challenges. Firstly, a supply for partial heart transplant donor grafts needs to be developed. This challenge is complicated by the scarcity of donor organs.

Partial heart transplantation: a new option for paediatric heart valve replacement
Nature Reviews Cardiology, Published online: 23 January 2024; doi:10.1038/s41569-024-00991-6Heart valve replacement in newborn babies remains an unsolved problem because currently used heart valve implants do not grow. This lack of implant growth mandates serial re-operations until adult-size valve implants can be fitted. Partial heart transplantation is a new approach to solve this problem by transplanting only the part of the heart that contains the necessary valve. (Source: Nature Reviews Cardiology)

3D printing of heart valves
Trends Biotechnol. 2024 Jan 17:S0167-7799(23)00323-2. doi: 10.1016/j.tibtech.2023.11.001. Online ahead of print.ABSTRACT3D printing technologies have the potential to revolutionize the manufacture of heart valves through the ability to create bespoke, complex constructs. In light of recent technological advances, we review the progress made towards 3D printing of heart valves, focusing on studies that have utilised these technologies beyond manufacturing patient-specific moulds. We first overview the key requirements of a heart valve to assess functionality. We then present the 3D printing technologies used to engineer hea...

Impact of transcatheter heart valve type on outcomes of surgical explantation after failed transcatheter aortic valve replacement: the EXPLANT-TAVR international registry
CONCLUSIONS: In the EXPLANT-TAVR global registry, BEV and SEV groups had different indications for surgical explantation, with more root replacements in SEV failure, but no differences in midterm mortality and morbidities. Further refinement of TAVR explantation techniques are important to improving outcomes.PMID:38224255 | PMC:PMC10786178 | DOI:10.4244/EIJ-D-23-00722 (Source: EuroIntervention)

Outcomes of Valve-In-Valve Transcatheter Aortic Valve Replacement
Structural valve degeneration (SVD) is increasingly seen given the higher rates of bioprosthetic heart valve (BHV) usage for surgical and transcatheter aortic valve replacement (TAVR). Valve-in-valve TAVR (VIV-TAVR) is an attractive alternate for patients who are otherwise at high risk for reoperative surgery. We compared patients undergoing VIV-TAVR and native-valve TAVR through a retrospective analysis of our institutional TVT database from 2013 to 2022. Patients undergoing either a native-valve TAVR or VIV-TAVR were included. (Source: The American Journal of Cardiology)

Transcatheter aortic valve implantation using coplanar and cuspal overlap techniques in Indian patients
CONCLUSION: In this study we achieved lower rates of PPI and new onset LBBB using COT technique in Indian patients using self-expandable prostheses. However valve deployment time, stroke rate and pericardial effusion were seen more in COT group. All cause mortality was low in cuspal overlap technique.PMID:38218314 | DOI:10.1016/j.ihj.2024.01.007 (Source: Indian Heart J)
