Advances in pediatric surgical and interventional techniques and medical care over the past 50 years have revolutionized the care of children with congenital heart disease. Survival to adulthood is now expected and, as such, there is a growing population of adults which is exceeding the pediatric population with congenital heart disease. Noninvasive cardiac imaging with modalities such as echoc...

Introduction Direct intramyocardial therapies aimed at treating myocardial regions affected by severe ischemia may benefit from CMR-guided interventional procedures. Although interventional MR approaches using active devices are considered to be the method of choice, potential tissue heating and altered mechanical properties are some of their limitations. Methods that have the capacity to visua...

The importance of intravascular ultrasound (IVUS) as an adjunctive technology facilitating optimal coronary interventional procedural technique has become increasingly evident over the past decade. IVUS is currently appreciated as an invaluable tool enabling better assessment of reference vessel size and coronary lesion morphology, including gross plaque characteristics and lesion length. Accor...

Magnetic resonance imaging (MRI) is a cutting edge imaging modality in detecting diseases and pathologic tissue. The superior soft tissue contrast in MRI allows better definition of the pathology. MRI is increasingly used for guiding, monitoring and controlling percutaneous procedures and surgery. The rapid development of interventional techniques in radiology has led to integration of imaging ...

BACKGROUND AND PURPOSE An animal spinal tumor model is needed to better simulate the clinical situation and to allow percutaneous puncture, which may provide an experimental platform for the new nonvascular interventional therapies. We established a rabbit spinal tumor model through a CT-guided percutaneous puncture inoculation technique for nonvascular interventional therapy. MATERIALS AND M...

Background: The femoral artery is conveniently located close to the surface; thus, it may be catheterized without much trouble. Interventional cardiology procedures and long-term hemodialysis access both make use of artery. Arteriography Doppler imaging its primary branch, profunda femoris superficial utilised create skin flaps for in reconstructive surgery breast, upper lower limbs.Methods: Ra...

As practicing interventional pain physicians, we were pleased to see the point-by-point evaluation of the recent ACOEM guidelines (1,2). Although the 400page ACOEM chapters at first glance appear impressive, through this analysis it becomes clear that the ACOEM chapters are fatally flawed. Unfortunately, insurance companies have been quick to accept any information that allows them to deny paym...

The IDEAL framework describes the stages of evaluation for surgical innovations. This paper considers the role of observational studies in the exploration and assessment stages. At the exploration stage, the surgical intervention is usually more widely used, and observational studies should collect prospective data from multiple surgeons, deal with factors such as case mix and learning, and pre...
