Hypertrophic Cardiomyopathy: Assessment with MR Imaging

A cardiac MRI focuses on the heart and attached blood vessels. It allows measurement of the volume and thickness of the heart's chambers and walls. An MRI also measures blood flow through the heart chambers and across the valves and can identify inflammation or blockages in the blood vessels Hypertrophic cardiomyopathy (HCM) is the most common genetic disease of the heart. HCM is characterized by a wide range of clinical expression, ranging from asymptomatic mutation carriers to sudden cardiac death as the first manifestation of the disease. Over 1000 mutations have been identified, classically in genes encoding sarcomeric proteins They are classified as dilated CMP, hypertrophic CMP, restrictive CMP, arrhythmogenic right ventricular (RV) CMP, specific CMP, and nonclassified CMP [1]. Cardiac MRI has become an important imaging technique for the diagnosis and follow-up of CMP The following are key perspectives from the 2020 American Heart Association/American College of Cardiology (AHA/ACC) guideline for the management of patients with hypertrophic cardiomyopathy (HCM): Shared decision making is recommended for all aspects of HCM care including genetic testing, activity, lifestyle, and therapy choices

The diagnosis and prognosis of hypertrophic cardiomyopathy (HCM) is generally clarified by noninvasive imaging, including screening by echocardiography and often refinement by cardiac magnetic resonance (CMR). Herein we will review the imaging modalities and findings relevant to the diagnosis and management of HCM Hypertrophic cardiomyopathy (HCM) is a genetic cardiovascular disease, defined by an increase in the left ventricular wall thickness (end-diastolic left ventricular wall thickness ≥ 15 mm or the equivalent relative to the body surface area in children) that is not solely explained by abnormal loading conditions MRI of hypertrophic cardiomyopathy: part 2, Differential diagnosis, risk stratification, and posttreatment MRI appearances Cardiovascular MRI is a useful imaging tool for the diagnosis of HCM and follow-up of patients after either surgical myomectomy or septal ablation therapy

  5. Hypertrophic cardiomyopathy (HCM), the most common genetic cardiomyopathy, is present in one in 500 of the general population and is caused by over 1,400 mutations in at least 11 genes encoding the cardiac sarcomere.1-4 Although the majority of patients with HCM remain asymptomatic with near-normal longevity, a small, but important, subset of patients are at increased risk for a wide range.

Hypertrophic cardiomyopathy (HCM) is distinguished by hypertrophy of either ventricle in the absence of a known cause, such as hypertension or aortic stenosis. The purpose of this chapter is to discuss the clinical features of HCM and imaging evaluation, with a focus on magnetic resonance imaging (MRI) for morphologic and functional assessment. Hypertrophic cardiomyopathy (HCM) is the most common genetic cardiomyopathy (prevalence of 1:500 in the general population) caused by mutations in genes encoding proteins of the cardiac sarcomere [1-5].A clinical diagnosis of HCM is confirmed when unexplained increased LV wall thickness is imaged (range 13-60 mm with average 22 mm) in the presence of a nondilated LV chamber [1, 3, 6] These findings are characteristic of hypertrophic cardiomyopathy - midcavity obstruction type. There is no evidence of left ventricular outflow tract obstruction (LVOT) obstruction. Discussion: The term cardiomyoapthy refers to a spectrum of myocardial disorders of varying etiology and pathopysiology that have in common diminished systolic and/or diastolic ventricular function ESC Clinical Practice Guidelines aim to present all the relevant evidence to help physicians weigh the benefits and risks of a particular diagnostic or therapeutic procedure on Hypertrophic Cardiomyopathy. They should be essential in everyday clinical decision making

Ischemic Cardiomyopathy

Hypertrophic cardiomyopathy is a chronic, genetic heart disease that causes the heart muscle to become thickened and enlarged, or hypertrophied. Hypertrophic cardiomyopathy also causes abnormal heart cells that are disorganized and, in some cases, scarred. In some patients, the mitral valve may be affected Hypertrophic obstructive cardiomyopathy is an inherited myocardial disease defined by cardiac hypertrophy (wall thickness ≥15 mm) that is not explained by abnormal loading conditions, and left ventricular obstruction greater than or equal to 30 mm Hg. Typical symptoms include dyspnoea, chest pain, palpitations, and syncope Hypertrophic cardiomyopathy (HCM) is a genetic disease characterized by abnormal myocardial hypertrophy, which can lead to a wide clinical spectrum, including sudden cardiac death and heart failure. Cardiac MRI has a significant role in establishing the diagnosis of HCM. In the three principal management issues related to HCM; testing of family members of affected individuals; assessing the. Asymmetric septal hypertrophy. Asymmetric septal hypertrophy is the most common type of hypertrophic cardiomyopathy in which the abnormal ventricular muscle thickening is confined to the interventricular septum, causing the walls of the lower heart chambers (typically the left ventricle) to become thick and stiff 1).The hypertrophy in this phenotype of hypertrophic cardiomyopathy is usually.

Difference Between Cardiomegaly and Cardiomyopathy

Hypertrophic Cardiomyopathy. Hypertrophic cardiomyopathy (HCM) is defined as hypertrophy of the myocardium more than 1.5 cm, without an identifiable cause . Other causes of left ventricular (LV) hypertrophy, such as long-standing hypertension, amyloidosis, and aortic stenosis must first be excluded before HCM can be diagnosed SNOWMASS, COLO. - Since the 2011 release of the current American College of Cardiology/American Heart Association guidelines on hypertrophic cardiomyopathy, several new evidence-based tools have emerged as being helpful in decision making regarding which patients should receive an implantable cardioverter-defibrillator (ICD) for primary prevention of sudden cardiac death, Dr. Rick A. Hypertrophic cardiomyopathy (HCM) is a genetic condition characterized by left ventricular hypertrophy that is not caused by other cardiac or causative systemic diseases. Patients can be asymptomatic or have chest pain, dyspnea, dizziness, or syncope. Sudden cardiac death may occur. The diagnosis can be established with a resting ECG and. Apical hypertrophic cardiomyopathy (HC) is a subtype of HC in which myocardial hypertrophy predominantly involves the apex of the left ventricle. Apical hypertrophic cardiomyopathy (HC) was first described by Sakamoto et al (1). in 1976. Apical HC accounts for 25% of all cases of HC in Japan, whereas in non Hypertrophic cardiomyopathy is most often caused by abnormal genes in the heart muscle that make the walls of the heart chamber (left ventricle) contract harder than normal. This extra work causes walls to thicken over time (hypertrophy) and start to become stiff and, in almost 2 out of 3 patients, leads to high pressures in the heart, often referred to as outflow tract obstruction
