Multi-institutional evaluation of the indications and radiation dose of functional cardiovascular computed tomography (CCT) imaging in congenital heart disease

Abstract Ventricular volumes and ejection fraction are often used in clinical decision making in patients with congenital heart disease (CHD). The referral diagnosis, radiation exposure and image quality of functional cardiac computed tomography (CT) in a relatively large cohort of patients of CHD has not been reported. This is a retrospective evaluation of functional CT studies performed in CHD patients from three institutions (1/2007–3/2013). Patient and scanner characteristics, radiation dose estimates and image quality were compared. Two hundred ninety-eight functional CT studies were evaluated. The most common referral diagnosis were tetralogy of Fallot (33 %), transposition complexes (24 %) single ventricle heart disease (15 %), and left sided obstruction (15 %). The reason for cardiac CT was presence of pacemaker (60 %), need for detailed coronary artery imaging (18 %), metallic artifact in CMR (12 %), evaluation of prosthetic valve function (4 %), and claustrophobia or BMI too large for the available MR scanner (6 %). 266 (89.3 %) scans allowed quantification of ventricular function, 25 (8.4 %) scans allowed qualitative assessment of function, and 7 (2.3 %) of the scans were non-diagnostic for functional analysis. Median DLP was 399 mGy cm (186, 614), and median effective dose was 5.5 mSv (2.6, 8.5). Radiation dose and image quality varied across institutions. Cardiac CT function...

If you have a CT heart scan score (also called coronary calcium score), what effect do statin cholesterol drugs have on stopping or slowing the increase in score? (Increasing scores pose increasing risk for heart attack and other cardiac events.) NONE. If you do nothing at all, the score increases by 25% per year, on average. If you take a statin drug, aspirin, and follow a low-fat diet, what my colleagues call “optimal medical therapy,” the score increases . . . 25% per year—no difference. Yet this is the “solution” that conventional doctors push on their patients, a “treatment” t...

Authors: Elwazir MY, Bois JP, Abouezzeddine OF, Chareonthaitawee P Abstract Infiltrative heart disease is an encompassing term referring to different pathological entities that involve infiltration of the myocardium by either abnormal substances or inflammatory cells. These infiltrates can impair cellular function, induce necrosis and fibrosis, or otherwise disrupt myocardial architecture resulting in a wide spectrum of structural and functional impairment. Depending on the specific disorder and stage of disease, patients may present with minimal cardiac abnormalities, or may have findings of advanced restrictive a...

The majority of doctors will tell you that there is nothing you can do to reverse fatty liver and that health problems such as cirrhosis and liver failure may be in your future that they will address with the awful “solution” of liver transplant. The truth is the opposite: fatty liver is easily and readily reversible in virtually everybody, provided you take action before irreversible changes take place and are given the right information and tools. In this video, I discuss the three basic phenomena that drive fat deposition, liver damage, and inflammation that lead to this condition: Carbohydrate consumption ...

Researchers are using artificial intelligence to measure a common marker of heart disease via lung cancer screenings. The research was presented at the annual meeting of the Radiological Society of North America (RSNA). Low-dose chest CT is approved for lung cancer screening in high-risk people, such as long-time smokers. While these CT scans are intended to diagnose lung cancer, coronary artery calcium, a measure of plaque in the arteries, is also visible on CT. The coronary artery calcium score derived from CT is a well-established measure that helps doctors decide who should get cholesterol-lowering preventive medicatio...

Positron emission tomography (PET) is an advanced radionuclide technique that has been available for decades. Originally used as a research tool that contributed to advances in the understanding of cardiovascular pathophysiology, it is now becoming established in clinical practice and is increasingly used in the diagnosis...

This study clearly goes against what has been the common wisdom for the last 30, 40 years” and may lead to less testing and invasive treatment for such patients in the future, said Dr. Glenn Levine, a Baylor College of Medicine cardiologist with no role in the research. Some doctors still may quibble with the study, but it was very well done “and I think the results are extremely believable,” he said. About 17 million Americans have clogged arteries that crimp the heart’s blood supply, which can cause periodic chest pain. Cheap and generic aspirin, cholesterol-lowering drugs and blood pressure medic...

We present a death from acute pyelonephritis in a setting of hypertensive heart disease, in which the unenhanced PMCT performed before postmortem examination was able to show florid bilateral perinephric fat stranding. This PMCT finding subsequently guided the pathologist to pay special attention to the kidney and take appropriate microbiology specimens to confirm the diagnosis. Perinephric fat stranding on PMCT may be a useful sign to alert the pathologist to consider acute pyelonephritis during the postmortem examination.

Authors: Pramono LA, Yuwono A Abstract Congenital hypothyroidism is the most treatable cause of mental retardation. It is also the most prevalent congenital endocrine disorder in childhood. A dramatic improvement can be made by early detection, diagnosis, and adequate treatment of levothyroxine in patients with congenital hypothyroidism. Severe cognitive impairment is associated with persistent disease in patients who have delayed or no treatment at all. In a modern era with complete healthcare facilities in a big city like Jakarta, the prevalence late-diagnosed congenital hypothyroidism is supposed to be very low....
