Abstract

Introduction: During the transcatheter aortic valve replacement (TAVR) procedure, hemodynamic measurements can be used to evaluate transcatheter heart valve (THV) performance. We hypothesized that the occurrence of a significant decrease in invasive aortic pressure immediately after annular contact by a self-expanding THV indicates effective annular sealing. This phenomenon could thus be used as a marker for the occurrence of paravalvular leak (PVL).

Methods: Thirty-eight patients undergoing TAVR procedure with a self-expandable Evolut R or Evolut Pro (Medtronic) valve prosthesis were included in the study. Drop in aortic pressure during valve expansion was defined as a decrease in systolic pressure of 30 mmHg immediately after annular contact. The primary endpoint was the occurrence of more than mild PVL immediately after valve implantation.

Results: A pressure drop was seen in 60.5% (23/38) of patients. More than mild PVL requiring balloon post-dilatation (BPD) was significantly more frequent in patients who did not have a systolic pressure decrease > 30 mmHg during valve implantation (46.7% [7/15] vs. 13.0% [3/23], respectively; p = 0.03). Patients without a systolic pressure decrease > 30 mmHg also had a lower mean cover index on computed tomography analysis (16.2% vs. 13.3%; p = 0.016). The 30-day outcomes were similar between the two groups, and echocardiography at 30 days demonstrated more than none/trace PVL in 21.1% (8/38) of patients, with no difference between the two groups.

Conclusion: A decrease in aortic pressure after annular contact is associated with an increased probability of good hemodynamic outcome after self-expanding TAVR implantation. In addition to other methods, this parameter could be used as an additional marker for optimal valve positioning and hemodynamic outcome during the implantation procedure.

术中压力变化对自扩张TAVR血流动力学结果的影响。
在经导管主动脉瓣置换术(TAVR)过程中,血流动力学测量可用于评估经导管心脏瓣膜(THV)的性能。我们假设,自扩式THV接触环后,有创主动脉压立即显著降低,表明环密封有效。因此,这种现象可以作为发生瓣旁漏(PVL)的标志。方法:38例采用自膨胀Evolut R或Evolut Pro(美敦力)瓣膜假体行TAVR手术的患者为研究对象。瓣膜扩张期间主动脉压下降的定义是在环接触后立即收缩压下降30 mmHg。主要终点是瓣膜植入后立即出现轻度以上的PVL。结果:60.5%(23/38)患者出现血压下降。在瓣膜植入期间收缩压下降不> 30 mmHg的患者中,需要球囊扩张(BPD)的轻度以上PVL更为常见(分别为46.7%[7/15]和13.0% [3/23];p = 0.03)。收缩压降低不大于30 mmHg的患者在计算机断层扫描分析中的平均覆盖指数也较低(16.2% vs 13.3%;p = 0.016)。两组30天的结果相似,30天的超声心动图显示21.1%(8/38)的患者超过无/微量PVL,两组之间无差异。结论:自扩式TAVR植入后,环形接触后主动脉压降低与良好血流动力学结果的可能性增加有关。除其他方法外,该参数可作为植入过程中最佳瓣膜定位和血流动力学结果的附加标记。

期刊介绍: Aims and Scope Cardiology and Therapy is an international, open access, peer reviewed (single-blind), rapid-publication journal dedicated to the publication of high-quality clinical (all phases), observational, real-world, and health outcomes research around the discovery, development, and use of cardiovascular therapies and interventions, including devices. Studies relating to diagnosis and diagnostics, pharmacoeconomics, public health, quality of life, as well as patient care, management and education are also encouraged. Areas of focus include, but are not limited to, ischaemic heart disease and acute cardiac care, myocardial, valvular, pericardial and congenital heart disease, vascular and pulmonary disease (including hypertension), arrhythmias, heart failure, non-invasive diagnostic techniques, and invasive and interventional cardiology as well as cardiovascular surgery. The journal is of interest to a broad audience of pharmaceutical and healthcare professionals and publishes original research, reviews, case reports/case series, trial protocols and short communications such as commentaries and editorials. Cardiolology and Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an international and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of quality research, which may be considered of insufficient interest by other journals. Rapid Publication The journal’s publication timelines aim for a rapid peer review of 2 weeks. If an article is accepted it will be published 3–4 weeks from acceptance. The rapid timelines are achieved through the combination of a dedicated in-house editorial team, who manage article workflow, and an extensive Editorial and Advisory Board who assist with peer review. This allows the journal to support the rapid dissemination of research, whilst still providing robust peer review. Combined with the journal’s open access model this allows for the rapid, efficient communication of the latest research and reviews, fostering the advancement of cardiovascular therapies. Personal Service The journal’s dedicated in-house editorial team offer a personal “concierge service” meaning authors will always have an editorial contact able to update them on the status of their manuscript. The editorial team check all manuscripts to ensure that articles conform to the most recent COPE, GPP and ICMJE publishing guidelines. This supports the publication of ethically sound and transparent research. Digital Features and Plain Language Summaries Cardiology and Therapy offers a range of additional features designed to increase the visibility, readership and educational value of the journal’s content. Each article is accompanied by key summary points, giving a time-efficient overview of the content to a wide readership. Articles may be accompanied by plain language summaries to assist readers who have some knowledge of, but not in-depth expertise in, the area to understand the scientific content and overall implications of the article. The journal also provides the option to include various types of digital features including animated abstracts, video abstracts, slide decks, audio slides, instructional videos, infographics, podcasts and animations. All additional features are peer reviewed to the same high standard as the article itself. If you consider that your paper would benefit from the inclusion of a digital feature, please let us know. Our editorial team are able to create high-quality slide decks and infographics in-house, and video abstracts through our partner Research Square, and would be happy to assist in any way we can. For further information about digital features, please contact the journal editor (see ‘Contact the Journal’ for email address), and see the ‘Guidelines for digital features and plain language summaries’ document under ‘Submission guidelines’. For examples of digital features please visit our showcase page https://springerhealthcare.com/expertise/publishing-digital-features/ Publication Fees Upon acceptance of your article for publication, authors will be required to pay the mandatory Rapid Service Fee of £3650/€4500/$5100. The journal will consider fee discounts for developing countries and this is decided on a case by case basis. Open Access All articles published by Cardiology and Therapy are published open access. Peer Review Process Upon submission, manuscripts are assessed by the editorial team to ensure they fit within the aims and scope of the journal and are also checked for plagiarism. All suitable submissions are then subject to a comprehensive single-blind peer review. Reviewers are selected based on their relevant expertise and publication history in the subject area. The journal has an extensive pool of editorial and advisory board members who have been selected to assist with peer review based on the afore-mentioned criteria. At least two extensive reviews are required to make the editorial decision, with the exception of some article types such as Commentaries, Editorials and Letters which are generally reviewed by one member of the Editorial Board. Where reviewer recommendations are conflicted, the editorial board will be contacted for further advice and a presiding decision. Manuscripts are then either accepted, rejected or authors are required to make major or minor revisions (both reviewer comments and editorial comments may need to be addressed). Once a revised manuscript is re-submitted, it is assessed along with the responses to reviewer comments and if it has been adequately revised it will be accepted for publication. Accepted manuscripts are then copyedited and typeset by the production team before online publication. Appeals against decisions following peer review are considered on a case by case basis and should be sent to the journal editor. Preprints We encourage posting of preprints of primary research manuscripts on preprint servers, authors’ or institutional websites, and open communications between researchers whether on community preprint servers or preprint commenting platforms. Posting of preprints is not considered prior publication and will not jeopardize consideration in our journals. Authors should disclose details of preprint posting during the submission process or at any other point during consideration in one of our journals. Once the preprint is published, it is the author’s responsibility to ensure that the preprint record is updated with a publication reference, including the DOI and a URL link to the published version of the article on the journal website.
