In fact, we are the only center in the region to offer all available VAD devices to patients. This means we can match the right person with the right device. VADs as used as:. Our experienced team includes nationally known experts in cardiac surgery, heart failure, transplant and heart-assist device technology. The team works closely together with surgeons, heart failure specialists, anesthesiologists and other specialists throughout the health system to provide the highest level of care for each and every patient.
This allow most patients to remain at home while they wait for a transplant or for their heart to heal. A team member is on call 24 hours a day, 7 days a week for emergency phone consultations or emergency outpatient clinic visits.

Ventricular Assist Devices
Education for You and Your Caregivers You are the most important member of your care team, and we are committed to ensuring you have the information you need to understand every aspect of treatment and of life after VAD implantation. Heart Transplant. Best Heart Hospital in NC. When it comes to your heart care, you want the very best. Duke University Hospital's nationally ranked cardiology and heart surgery program is ranked the best in North Carolina by U. Open in a separate window. Figure 1. RVAD The clinical settings in which RVAD therapy are most commonly employed include acute myocardial infarction, pulmonary embolism, pulmonary hypertension, myocarditis, post-cardiotomy shock, cardiac transplantation, and LVAD implantation.
Second Generation: Continuous Axial Flow Pumps Because first generation pulsatile pumps were limited by their large size, high noise emission, and durability issues leading to frequent malfunction and morbidity, research to develop smaller and more reliable devices were initiated and continued through the s [ 17 ].
Figure 2. Figure 3. Current State of The Art 3. CADs in Clinical Settings Today After five-plus decades of dedicated research aimed at developing blood pump technologies to support the failing heart, a cadre of devices capable of delivering different levels of support at different levels of invasiveness are now available to treat different varieties and severities of cardiac malfunction.
Short-term Circulatory Support Extracorporeal membrane oxygenation ECMO Figure 4 A is a form of cardiopulmonary bypass that is used as a bridge to recovery, transplantation, or mechanical circulatory support [ 49 ]. Figure 4. Pediatric Pumps Conventional continuous flow VADs were designed specifically to treat adult patients, who comprise the vast majority of the end-stage CHF population and so tend to be too large for use in pediatric patients weighing less than 25 kg 55 lbs.
Clinical Complications of Current VADs In spite of the increasing number of VAD options currently available to patients due to revolutionary advances in cardiac support technologies, numerous challenges still persist. Figure 5. Innovations for Effective Long-Term Cardiac Support The rate of DLI, thromboembolic incidents, and bleeding problems must be curtailed if long-term cardiac support is to become a viable treatment option for end-stage CHF patients. Alternative Powering Methods for Untethered Cardiac Support To provide long-term CAD patients better quality-of-life, various powering methods have been proposed to minimize or eliminate extracorporeal power requirements that limit patient autonomy and contribute to patient stress over potential power delivery failures e.
Transcutaneous Energy Transfer System Transcutaneous energy transmission TET technology Figure 6 A that transfers power across intact skin makes devices completely implantable and therefore free of the risk of DLI [ 17 ]. Figure 6. Muscle-powered VADs The use of electrically stimulated skeletal muscle as an endogenous power source to drive circulatory support systems is another alternative that is currently under study. Figure 7. Non-Blood-Contacting Cardiac Assist Devices Despite innumerable CAD designs and material modifications made over the decades in an attempt to eliminate chronic pump thrombosis, the situation still persists while the precise dosage and frequency of long-term antithrombotic therapies remain ambiguous [ 20 , 21 ].
Copulsation Direct Cardiac Compression Sleeve A normal heart with a ventricular ejection volume of about Figure 8. Counterpulsation Extra-Aortic Balloon Pump Another form of circulatory support for CHF patients that provides effective cardiac unloading and patient stabilization is displacement of blood from the aorta during the diastolic phase of the cardiac cycle.
Passive Periventricular Restraint Passive periventricular restraint, which involves wrapping the entire epicardial surface with a sleeve-like prosthetic to provide circumferential diastolic support to the failing heart, is an approach that evolved from a surgical procedure known as cardiomyoplasty CMP in which the ventricles were wrapped with the latissimus dorsi LD muscle flap and stimulated to contract in synchrony with the systolic portion of the cardiac cycle.
CADs in Summary Key characteristics of the large and expanding family of cardiac assist devices developed in the past, used in the present and slated for the future are summarized in Table 1 below. Conclusions Since its inception in the early s, a remarkable amount of research and development has been performed in an effort to improve and expand the field of cardiac assist devices.
