Book excerpt: "This book provides the first authoritative account of the use of stentless bioprostheses in cardiac surgery." "The concept of the stentless heart valve was borne from the observation of natural heart valves in the operating theatre. Many surgeons now believe that the porcine stentless bioprosthesis offers significant advantages over the traditional stented valve, including improved durability (minimum calcification, no tears), biocompatability and automatic ventricular function preservation." "These issues, along with the suitability of the various valves now available are discussed in full by leading experts in the field." "The text is divided into three main sections; historical background, stentless valve technology and clinical experience. Each chapter is fully referenced and complemented by photographs and operative line illustrations, the majority of which are in full colour." --Book Jacket.

Download or read book Aortic Valve Replacement and the Stentless Freedom SOLO Valve written by Laurens Willem Lodewijk Maria Wollersheim and published by . This book was released on 2016 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aortic valve stenosis has become the most prevalent valvular heart disease in Europe and North America, and is generally caused by age-related calcification of the aortic valve. For most patients, severe symptomatic aortic stenosis needs effective mechanical relief in the form of valve replacement before it becomes a lethal obstruction to outflow. This dissertation focuses on the evaluation and performance of the stentless Freedom SOLO bioprosthesis. We found several clinical and hemodynamic advantages for the Freedom SOLO. Due to the implantation technique, there are few patients that require the implantation of a permanent pacemaker. In addition, the postoperative valvular gradients are excellent and remain stable during midterm follow-up, with large effective orifice areas. Furthermore, structural valve deterioration and aortic valve reoperation are infrequent. However, because of its specific design and implantation technique, not every patient profits from this valve and therefore patient selection is crucial. Based on our extensive implant experience we presented our contraindications for the use of the Freedom SOLO. We discussed several options in the event of a degenerated Freedom SOLO and reported for each technique the pitfalls. Additionally, 4D flow MRI, a new imaging modality, was used to compare stentless and stented valves in a pilot study. At this moment, the Freedom SOLO should be considered for use in patients with a small aortic root, or in patients that in any other way are at risk for prosthesis-patient mismatch, or in patients that could profit from the superior hemodynamic performance and the large effective orifice area.

Download or read book Calcific Aortic Valve Disease written by Elena Aikawa and published by BoD – Books on Demand. This book was released on 2013-06-12 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to population aging, calcific aortic valve disease (CAVD) has become the most common heart valve disease in Western countries. No therapies exist to slow this disease progression, and surgical valve replacement is the only effective treatment. Calcific Aortic Valve Disease covers the contemporary understanding of basic valve biology and the mechanisms of CAVD, provides novel insights into the genetics, proteomics, and metabolomics of CAVD, depicts new strategies in heart valve tissue engineering and regenerative medicine, and explores current treatment approaches. As we are on the verge of understanding the mechanisms of CAVD, we hope that this book will enable readers to comprehend our current knowledge and focus on the possibility of preventing disease progression in the future.

Download or read book Aortic Valve Transcatheter Intervention written by Marco Zimarino and published by John Wiley & Sons. This book was released on 2021-05-07 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aortic Valve Transcatheter Intervention Calcific aortic stenosis (AS) is the most common heart valve anomaly, with a largely age-dependent prevalence, a calculated annual incidence rate in the range of 4-5% in general populations and up to 6% in patients aged 75 years and over. Surgical aortic valve replacement (SAVR) was previously the only option available to patients with symptomatic, severe aortic stenosis. After the first-in-human transcatheter aortic valve implantation (TAVI) was performed by Alain Cribier in 2002, the treatment strategy for patients with symptomatic AS has been revolutionized. Since then, TAVI has grown exponentially, as a result of accruing evidence demonstrating safety and efficacy, and reduced invasiveness compared with SAVR. TAVI devices are continuously expanding to include several valve design options. As this strategy is continuously evolving to treat younger patients and lower-risk populations, aside from the long-term durability of the valve systems, procedural safety will become the focus of newer-generation devices. This book is a practical handbook devoted to the optimization of TAVI procedures, through a focused containment of complications. Through an integrated evaluation of the clinical status, imaging techniques and laboratory findings, the authors provide readers with clear messages on preventive and therapeutic recommendations.

Download or read book Cardiovascular Calcification and Bone Mineralization written by Elena Aikawa and published by Springer Nature. This book was released on 2020-07-01 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book covers the basic science and clinical aspects of cardiovascular calcification and bone mineralization. Cardiovascular calcification is the leading predictor of cardiovascular morbidity and mortality, with a predictive value more significant than blood lipid levels. The presence of calcific mineral in cardiovascular tissues alters biomechanical performance, increasing workload on the heart and potentiating atherosclerotic plaque rupture and subsequent heart attack and stroke. This book examines the role of calcification in cardiovascular disease covering topics such as calcification in the atherosclerotic plaques and aortic valves arteries and valves, aortic valve replacement, peripheral artery disease, imaging of early calcification and target discovery. In addition, various forms of ectopic calcification as well as mechanisms of bone mineralization are discussed. Cardiovascular Calcification and Bone Mineralization is an essential resource for clinicians, researchers, and other medical professionals in cardiology, pathology, and biomedical engineering.

Download or read book Transcatheter Aortic Valve Implantation written by Arturo Giordano and published by Springer. This book was released on 2019-07-01 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides comprehensive information on transcatheter aortic valve implantation (TAVI), which was introduced for the treatment of aortic valve disease less than two decades ago. It explains how TAVI has delivered satisfactory results even in high and intermediate risk patients and outlines how it continues to evolve, thus requiring awareness of state of the art approaches to indication, risk stratification, device choice, procedure, and follow-up. In addition, it reports on the complex and multidisciplinary approach needed to maximize the efficacy, safety, and appropriateness of TAVI, providing detailed clinical, interventional and surgical perspectives focusing on the development of this cardiovascular intervention. Starting with the history of TAVI, addressing the interventional anatomy of aortic valve disease, and reporting on the expert authors’ day-to-day experiences, this highly informative book offers an essential update for all cardiologists and surgeons interested in transcatheter aortic valve implantation, as well as any clinician, decision-maker and stakeholder involved in patient selection, procedural management, and follow-up.

Download or read book In Situ Aortic Root in Vitro Testing of the Stented and Stenless Porcine Aortic Heart Valves written by Sean Parker and published by . This book was released on 1999 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Background - The stent, Delrin® support frame, for porcine heart valves has been blamed for reduced durability of these valves due to the additional stress caused by the relative stiffness of the stent. There is a tendency among surgeons to do away with the stent in the aortic position and use porcine stentless valves which are sewn directly in the aortic position after removing diseased valve. These stentless valves are extremely difficult to test and no appropriate holder has been designed for this purpose. New approach for in vitro testing of these valves has been developed at Sheihigh, Inc., Millburn NJ. The stentless valves are sewn in real porcine heart; the aortic root is dissected out and the aortic root is connected to a holder then inserted in the Pulse Duplicator System. This aortic root is kept fresh with antiseptic solutions but not fixed with glutaraldehyde since it can become stiffer than the natural aorta. Method - In vitro hemodynamics, blood flow performance, of porcine bioprostheses were tested under physiological conditions using the pulse duplicator system. The system is comprised of a test chamber in which the porcine bioprosthesis is inserted, a pressure transducer, a flow probe, an amplifier pair, and real time software to analyze the fluid dynamics of stented and unstented porcine bioprostheses. Thirteen Shethigh Porcine valves were tested in the Pulse Duplicator System for this study which include 7 - 25mm valve, 4 stented and 3 stentless, and 6 - 23mm valves, 3 stented and 3 stentless. Results - Preliminary results from testing three of each stented and stentless 23mm valves at a rate of approximately 90 Beats Per Minute (BPM) showed an average of a 6% increase in the Effective Orifice Area (EOA) of the Stentless bioprosthesis over the standard Stented bioprosthesis. The EOA ranged from a high of 2.41cm2 for the 25mm stentless to a low of 21 8cm2 for the 25mm stented bioprosthesis. The mean EOA for the stented bioprostheses was 1.94cm2 and 2.06cm2 for the stentless bioprostheses. Conclusion - The series of tests which were performed using aortic roots and sizers to size the aortic root to implant the valve into the proper size root revealed that sizing the root is critical when trying to achieve a maximum Effective Orifice Area. Sizing of the stented valve implanted is not as critical due to the stent providing a predefined area for the valve, but then there is no means for the valve to distend at high flow rates. The stentless bioprosthesis is superior to the standard bioprosthesis in the sense there is no stress on the valve comparable to the stented bioprosthesis. At high flow rates the EOA of the stentless valve is not limited to the inside diameter of the valve because it is allowed to distend outward at times of high flow rates. Using stentless valves is of importance at times of high flow rates in order to eliminate the stenosis, the abnormal narrowing of the orifice, opening, in a heart valve, which is produced in stented valves.
