(Press-News.org) Washington, DC (March 24, 2015) - As congenital heart disease (CHD) treatment advances, children with these conditions are living into adulthood, and over time, they may need additional treatment. A new expert consensus paper released today by the Society for Cardiovascular Angiography and Interventions (SCAI), American Association for Thoracic Surgery (AATS), American College of Cardiology (ACC), and The Society of Thoracic Surgeons (STS) provides guidance on transcatheter pulmonic valve replacement, or tPVR, for children and adults who were previously treated for CHD.
Pulmonary valve replacement may be necessary in patients who have had certain types of CHD repaired with reconstruction of the right ventricular outflow tract (RVOT) - an area of the heart that carries blood out of the right ventricle. As patients with CHD live longer than they did in the past, dysfunction of the repair can occur over time. In the past, these patients would require a repeat open-heart surgery. Today, tPVR offers a less invasive option for many patients.
"Transcatheter valve treatments are allowing us to offer less invasive options to patients who were previously treatable only with open-heart surgery, or may not have been eligible for treatment at all," said Ziyad M. Hijazi, MD, MPH, FACC, MSCAI, chair of the writing committee, acting chief medical officer and chairman of the Department of Pediatrics at Sidra Medical and Research Center in Doha, Qatar. "These procedures are complementing standard surgical approaches, allowing physicians to provide greater options for our patients."
As treatment advances, cardiologists and surgeons have the opportunity to collaborate in determining the best treatment option for each patient. The consensus paper stresses that tPVR treatment recommendations should be made by a heart team consisting of interventional cardiologists, cardiac surgeons, noninvasive cardiologists, and cardiac anesthesiologists and radiologists.
"There is strong consensus that these new valve therapies should be performed under the guidance of a multi-disciplinary heart team, involving both interventional cardiologists and surgeons," said Dr. Hijazi. "Increasing evidence shows a team-based approach provides the greatest quality care for patients with complex heart disease, including patients considering tPVR."
The paper further recommends that institutions offering tPVR perform at least 150 congenital/structural catheterization procedures per year, including 100 that are interventional, as well as 100 open-heart congenital surgical procedures. Institutions should have the heart-lung bypass support known as extracorporeal membrane oxygenation (ECMO); echocardiography, cardiac CT and cardiac MRI imaging capabilities; a cardiovascular catheterization laboratory (cath lab); and hemodynamic (blood pressure and electrocardiography) evaluation. Additionally, institutions should participate in a national registry. Because tPVR is a new treatment option, the committee stressed the importance of continuing to collect data on the procedure, including total numbers of tPVR in the United States and numbers of procedures by operator and institution.
Physicians performing tPVR should perform at least 100 interventional cases per year, including 50 congenital/structural interventional cases. They should have experience with balloon valvuloplasty as well as stenting within pulmonary arteries and RVOT. The paper also recommends physicians attend peer-to-peer training and a simulated case if available. The first three procedures performed should be under the guidance of an experienced physician.
"As physician experience with tPVR increases over time, complication rates are declining significantly, reflecting the importance of experience in improving patient outcomes," said Dr. Hijazi.
A committee of cardiac surgeons and interventional cardiologists developed the recommendations, which were created to help physicians and hospitals offer consistent and appropriate care to tPVR patients. The new paper is the third in a series of expert consensus papers for hospitals and physicians performing transcatheter valve procedures. The first two papers discussed aortic and mitral valve procedures.
The document, titled "Operator & Institutional Requirements for Transcatheter Valve Repair and Replacement, Part III - Pulmonic Valve," will simultaneously e-publish in Catheterization and Cardiovascular Interventions (CCI), Journal of Thoracic and Cardiovascular Surgery (JTCVS), Journal of the American College of Cardiology (JACC) and The Annals of Thoracic Surgery.

DETROIT - Major League Baseball pitchers who underwent a second Tommy John surgery saw their performance decline and their career shortened, according to researchers at Henry Ford Hospital.
In a retrospective, case-controlled study, researchers analyzed performance and longevity data of 33 pitchers who had a second surgery following the original elbow reconstruction between 1996 and 2012 and compared them with pitchers of similar age who had no prior Tommy John surgery. Key findings for pitchers after a second surgery:
65 percent returned to pitching at MLB level.

Socio-economic inequalities between First Nations communities, and also between these communities and the non-Aboriginal population of Canada, determine the nature, the intensity and the direction of First Nations migration flows. Pursuing educational careers, finding work, and seeking better health and living conditions are the main reasons for First Nations migration. These are the findings of research by Marilyn Amorevieta-Gentil, Robert Bourbeau and Norbert Robitaille, of the University of Montreal, which were presented ...
DURHAM, N.C. -- For people infected with the human papilloma virus (HPV), the likelihood of clearing the infection and avoiding HPV-related cancer may depend less on the body's disease-fighting arsenal than has been generally assumed.
A new study finds that the body's ability to defeat the virus may be largely due to unpredictable division patterns in HPV-infected stem cells, rather than the strength of the person's immune response.
If the mathematical model behind the findings holds up, it could point to ways of tweaking the way infected cells divide in order to make ...
It's no surprise that some of the most celebrated leaders in the business world also happen to be self-promoting narcissists.
New research from Brigham Young University's Marriott School of Management finds those strong characteristics are not such a bad thing--as long as those leaders temper their narcissism with a little humility now and then.
"Just by practicing and displaying elements of humility, one can help disarm, counterbalance, or buffer the more toxic aspects of narcissism," said Bradley Owens, assistant professor of business ethics at BYU. "The outcome ...
Great leaders are often good communicators. In the process of communication, the relationship between leaders and their followers develops spontaneously according to new research from the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig and the State Key Laboratory of Cognitive Neuroscience and Learning and IDG/McGovern Institute for Brain Research in Beijing. When a member becomes the group leader, the leader's brain activity in the left temporo-parietal junction, known as representing others' mental states, begins to synchronize with that in the ...
Adding two non-invasive imaging tests to traditional cardiovascular disease risk factor assessment more precisely predicts a healthy patient's future risk of heart attack, stroke, or premature death, according to a study led by Icahn School of Medicine at Mount Sinai and published in the March 24 edition of the Journal of the American College of Cardiology (JACC).
"Using imaging tests to detect disease in carotid or coronary arteries before it causes symptoms can better identify healthy individuals at increased risk than our current, traditional risk assessment methods," ...
Numerous studies have documented racial differences in deaths from cancer among non-Hispanic whites and African Americans, but little has been known about survival outcomes for Asian Americans who have been diagnosed with cancer, until now. A new study from Quoc-Dien Trinh, MD and colleagues at Brigham and Women's Hospital (BWH) examined cancer patients in eight different Asian American subgroups and found their cancer-specific mortality (CSM) was substantially lower than that of non-Hispanic white patients. The findings are published in the March 20 issue of the Journal ...
Young adults who were raised in educated households develop higher cognitive ability than those who were brought up in less ideal environments, according to a new study conducted by researchers at Virginia Commonwealth University, the University of Virginia and Lund University in Sweden.
While the study does not refute previous findings that DNA impacts intelligence, it does prove that environmental influences play a significant role in cognitive ability as measured in early adulthood.
The study compared the cognitive ability - as measured by IQ - of 436 Swedish male ...
WINSTON-SALEM, N.C. - March 24, 2015 - Kidney transplantation outcomes from deceased African-American donors may improve through rapid testing for apolipoprotein L1 gene (APOL1) renal risk variants at the time of organ recovery, according to a new study led by researchers at Wake Forest Baptist Medical Center.
Variation in the APOL1 gene is associated with up to 40 percent of all kidney diseases in African-Americans who undergo dialysis or kidney transplantation, and APOL1 kidney disease risk variants are only present on the chromosomes of individuals who possess recent ...
ROCHESTER, Minn. -- Researchers at Mayo Clinic have shown that it is possible to detect endometrial cancer using tumor DNA picked up by ordinary tampons. The new approach specifically examines DNA samples from vaginal secretions for the presence of chemical "off" switches -- known as methylation -- that can disable genes that normally keep cancer in check.
The finding is a critical step toward a convenient and effective screening test for endometrial cancer, which is the most common gynecologic malignancy in the United States. The results are published in the journal ...
