The Ross Heart Failure Classification was developed to provide a global assessment of heart failure severity in infants, and has subsequently been modified to apply to all pediatric ages. The modified Ross Classification incorporates feeding difficulties, growth problems, and symptoms of exercise intolerance into a numeric score comparable with the NYHA classification for adults.
Cardiology
Edinburgh Claudication Questionnaire
The Edinburgh Claudication Questionnaire has been shown to be 91 percent specific and 99 percent sensitive for diagnosing intermittent claudication in symptomatic patients.
Diagnosis of Autoreactive Pericarditis
Recently, the term “autoreactive pericarditis” has been introduced to describe patients with identification of elements indicative of an autoimmune response who would otherwise be classed as idiopathic.
Definitions and Classification of Office Blood Pressure Levels (2013 ESH/ESC)
The recommended classification is unchanged from the 2003 and 2007 ESH/ESC guidelines. Hypertension is defined as values >/=140 mmHg systolic blood pressure (SBP) and/or >/=90 mmHg diastolic blood pressure (DBP), based on the evidence from randomized controlled trials (RCTs) that in patients with these blood pressure (BP) values treatment-induced BP reductions are beneficial.
Indications for Ambulatory Electrocardiography (AECG)
There are numerous potential clinical uses of the 12-lead ECG. The ECG may reflect changes associated with primary or secondary myocardial processes (e.g., those associated with coronary artery disease, hypertension, cardiomyopathy, or infiltrative disorders), metabolic and electrolyte abnormalities, and therapeutic or toxic effects of drugs or devices. Electrocardiography serves as the gold standard for the noninvasive diagnosis of arrhythmias and conduction disturbances, and it occasionally is the only marker for the presence of heart disease.
Diagnostic Criteria for Marfan Syndrome (MFS)
Marfan syndrome is currently diagnosed using criteria based on an evaluation of the family history, molecular data, and 6 organ systems.
Indications for Aortic Valve Replacement (AVR) in Aortic Stenosis (AS)
Aortic valve stenosis is usually defined by restricted systolic opening of the valve leaflets, with a mean transvalvular pressure gradient of at least 10 mm Hg.
Classification for Chagas Cardiomyopathy
Chagas’ disease is caused by a protozoan parasite, Trypanosoma cruzi, that is transmitted to humans through the feces of infected bloodsucking insects in endemic areas of Latin America, or occasionally by nonvectorial mechanisms, such as blood transfusion. Cardiac involvement, which typically appears decades after the initial infection, may result in cardiac arrhythmias, ventricular aneurysm, congestive heart failure, thromboembolism, and sudden cardiac death.
Clinical Indications and Contraindications to Percutaneous Coronary Intervention (PCI)
Percutaneous coronary interventions (PCI) include percutaneous transluminal coronary angioplasty (PTCA) with or without stenting. Primary indications are treatment of angina pectoris (stable or unstable), myocardial ischemia, and acute MI (particularly in patients with developing or established cardiogenic shock).
