Ventricular Assist Devices (VADs) are small pumps that take over the work of the heart in pumping the blood through the body. Patients who need a heart transplant, but for whom there is no donor heart available, might be given a VAD for what’s called a bridge-to-transplant while they wait for a donor.
PediMag, the pediatric version of the adult device, CentriMag, is an external device designed for short-term use in infants with heart failure. PediMag can also be used to support children after heart transplant surgery if they experience organ rejection and need time for their hearts to rest and heal, according to Jonathan M. Chen, MD, Surgical Director of Pediatric Heart Transplantation at Morgan Stanley Children’s Hospital of New York. Dr. Chen has extensive experience treating children with heart failure and has recently authored an account of his first successful use of the PediMag as a biventricular bridge-to-transplant in an infant.

Here’s an important equation that all of us — doctors include — should know about healthcare, but don’t:
More ≠ Better
“More does not equal better” applies to diagnostic procedures, screening tests meant to identify problems before they appear, medications, dietary supplements, and just about every aspect of medicine.
That scenario is spelled out in alarming detail in the Archives of Internal Medicine. Clinicians at the Cleveland Clinic describe the case of a 52-year-old woman who went to her community hospital because she had been having chest pain for two days. She wasn’t having symptoms of a heart attack, such as shortness of breath, unexplained nausea, or a cold sweat, and her electrocardiogram and other tests were fine. The woman’s doctors concluded that her chest pain was probably due to a muscle she had pulled or strained during her recently begun exercise program to lose weight.
To “reassure her” that she wasn’t having a heart attack, the emergency department team recommended she have a CT scan of her heart. This noninvasive procedure can spot narrowings in coronary arteries and other problems that can interfere with blood flow to the heart. When it showed a suspicious area in her left anterior descending artery (a key artery nourishing the heart), she underwent a coronary angiogram. This involves inserting a thin wire called a catheter into a blood vessel in the groin and deftly maneuvering it into the heart. Once in place, equipment on the catheter is used to make pictures of blood flow through the coronary arteries. Read more »

Mr. Ron Murray, a tranplant heart recipient, tells his story:
From the video:
“If the transplant issue ever comes up for anyone listening, that’s almost the first thing they would think, too. If I had time to think about it over that year, I would have realized ‘Oh, my God.’ I would have apprehension all built up about how I would react to…I mean is it going to change my way of thinking? Is it going to alter my own thoughts? None of that holds up, ultimately.
When I realized that there was going to be forever an emotional component, and maybe a spiritual component to this thing that I hadn’t thought about, is when I became –- God, I don’t even know if I can tell you about it –- that I began to grieve for the donor, that brought me to tears several of those nights.
