Transcatheter and Surgical Approaches to Complications of Transcatheter Procedures: Current Trends and Future Challenges

Dear Colleagues,

Over the last years, transcatheter procedures [such as transcatheter aortic valve implantation (TAVI), transcatheter mitral and tricuspid valve edge-to-edge repair (M-TEER and T-TEER), transcatheter mitral and tricuspid repair or replacement (TMVR and TTVR), transcatheter left atrial appendage occlusion (LAAO), transcatheter paravalvular leak (PVL) closure, and transcatheter closure of patent foramen ovale (PFO)] have become an important minimally invasive alternative to open-heart cardiac surgery for patients at high surgical risk and suffering from severe valve disease. Modern cardiac imaging, the computational tools for the 3D imaging analysis of cardiac and vascular structures, and the use of fusion technologies during procedures have become important key factors for the success of percutaneous procedures. Similarly, the evolution of devices has helped in improving the hemodynamic results, simplifying the procedural steps and lowering the rate of procedural unsuccess, vascular injury, paravalvular leak, and permanent pacemaker implantation.

However, adverse events still represent a daunting issue of transcatheter procedures, as both short term (e.g., valve mal-positioning) and long term (e.g., device endocarditis) complications damper the benefits of the procedure and might pose patients at extremely high risk for their urgent or emergent treatment. This Special Issue aims to summarize the latest advances in the treatment of transcatheter procedures related complications, focusing on both percutaneous and surgical approaches.

By reading this Special Issue, cardiologists and cardiac surgeons involved in modern heart teams should easily improve their knowledge by learning about the latest trends in transcatheter procedures as presented by experts in the field. Both original research contributions and state-of-the-art reviews are welcome.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Cardiovascular Development and Disease is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
