“…As such, early HCM diagnosis is rare, with the majority of patients initially diagnosed for hypertension or Type II diabetes, leaving room for a more accurate and reliable noninvasive diagnostic method which would improve overall outcomes [11]. A key part of the definition of HCM is the presence of at least one thickened segment in a nondilated ventricle [12]. However, the location of these segments can vary, and the radiographic limitations of usual diagnostic methods such as transthoracic echocardiography mean there is a role for CMR to more accurately image these segments and identify a previously undiagnosed subset of HCM patients.…”

Heart failure affects 1–2% of the adult population and one of the main contributors to its development is cardiomyopathy. Assessing a patient's risk for adverse events in heart failure is challenging and made more difficult by the heterogenous phenotypic expression of the disease. Cardiac MRI has long been a gold standard measure of myocardial function and anatomy due to its high spatial and temporal resolution. More recently, it has been posited to play a more critical role in the diagnosis and prognosis of cardiomyopathy-related heart failure. Given the limitations of more commonly used imaging modalities, increasing the clinical use of cardiac magnetic resonance imaging could potentially improve the prognosis of specific subgroups of patients at risk of adverse cardiac events.

“…[4–7] It is a useful technique in evaluating patients with hypertrophic cardiomyopathy and is preferred over other imaging modalities. [8,9] The present study revealed that hypertrophic obstructive cardiomyopathy could cause an illusion of aortic stenosis on imaging (cardiac MRI and transesophageal echocardiography). Cardiac physicians should always be vigilant and respond rationally to such patients.…”

A case report and analysis of hypertrophic obstructive cardiomyopathy causing an illusion of aortic stenosis

Rationale: This study aimed to report a case of hypertrophic obstructive cardiomyopathy causing an illusion of aortic stenosis on imaging. Patient concerns: A 71-year-old woman presented with chest tightness after activity for 1 year and coughing for 2 months. A systolic 3/6 grade murmur was found in the third intercostals of the left border of sternum. Transthoracic echocardiography, transesophageal echocardiography, and magnetic resonance imaging (MRI) were all suggestive of aortic stenosis and left ventricular outflow tract stenosis. Diagnosis: The patient was diagnosed with “severe aortic stenosis (bicuspid deformity), left ventricular outflow tract stenosis (moderate), and grade II cardiac function.“ She was advised aortic valve replacement and left ventricular outflow tract dredging. However, no aortic valve lesion was found during the operation, and the diagnosis was changed to “hypertrophic obstructive cardiomyopathy.” Interventions and outcomes: The morrow procedure was performed, and the patient recovered well after the operation. Hypertrophic obstructive cardiomyopathy was found to cause an illusion of aortic stenosis on imaging. Lessons: Special attention and rational treatment should be paid to such patients. In addition, further studies are needed to distinguish between the two diseases to reduce misdiagnosis.

“…МРТ сердца обладает определенными преимуществами перед эхокардиографией в диагностике ГКМП. Сюда относятся точное определение границы эндокарда, возможность построения изображений в различных плоскостях, охват обоих желудочков с более точной оценкой их размеров, функции и степени гипертрофии, лучшая идентификация локальной гипертрофии, визуализация и количественная оценка фиброза миокарда [6].…”

Цель исследования-проанализировать госпитальные результаты хирургического лечения больных с обструктивной гипер трофической кардиомиопатией. Материал и методы. С ноября 2017 г. по март 2019 г. в РНЦХ им. акад. Б.В. Петровского были пролечены 15 больных (8 женщин и 6 мужчин) с обструктивной формой гипертрофической кардиомиопатии и тяжелой недостаточностью митрального клапана. Средний возраст больных составил 55,9±7,1 года. Все больные предъявляли жалобы, связанные с хронической сердечной недостаточностью на уровне III функционального класса по NYHA и относительной коронарной недостаточностью. Результаты. Хирургическая коррекция обструкции выходного тракта ЛЖ, пластика митрального клапана с устранением его переднесистолического движения были технически успешны во всех случаях. Необходимость в протезировании митрального клапана отсутствовала у всех больных. Жалобы, связанные с сердечной недостаточностью, соответствовали I-II классу по NYHA в раннем послеоперационном периоде. Выводы. Тщательное предоперационное планирование с всесторонним анализом гемодинамических и анатомических особенностей ЛЖ и, безусловно, определенный хирургический опыт являются ключевыми факторами не только адекватной коррекции обструкции ВТЛЖ (в том числе с сохранением АВ-проведения), но и сохранения нативного митрального клапана. Ключевые слова: обструктивная гипертрофическая кардиомиопатия, обструкции выходного тракта ЛЖ, митральная недостаточность, SAM-синдром, хирургическое лечение, пластика митрального клапана.

Abstract: [first paragraph of article]Cardiac magnetic resonance imaging (CMR) is a useful technique in the evaluation of patients with suspected or diagnosed hypertrophic cardiomyopathy (HCM), and has an added value over other imaging modalities.
