Pressure Tracings in Hypertrophic Cardiomyopathy With Dynamic Midventricular Obstruction

Pressure Tracings in Hypertrophic Cardiomyopathy With Dynamic Midventricular Obstruction

A 50-year-old man was admitted for evaluation of syncope. Clinically, he had an irregular pulse and an ejection systolic murmur loudest at the left sternal border. Transthoracic echocardiography revealed hypertrophic cardiomyopathy (HCM) with midventricular obstruction and apical aneurysm with maximum pressure gradient greater than 74 mm Hg. Coronary angiogram showed normal coronary arteries. L...

Clinical implications of midventricular obstruction in patients with hypertrophic cardiomyopathy.

OBJECTIVES We investigated the prevalence, clinical characteristics, and prognosis of hypertrophic cardiomyopathy (HCM) patients with midventricular obstruction (MVO). BACKGROUND Previous descriptions of patients with MVO have been confined to case reports or small patient series, and this subgroup of HCM patients has therefore remained underrecognized. METHODS The study population included...

A notch in time: midventricular hypertrophic cardiomyopathy.

Hypertrophic cardiomyopathy with midventricular obstruction and apical aneurysm formation in a single family: case report

BACKGROUND Hypertrophic cardiomyopathy (HCM) is an extremely heterogeneous disease. An under recognized and very often missed subgroup within this broad spectrum concerns patients with left ventricular (LV) apical aneurysms in the absence of coronary artery disease. CASE PRESENTATION We describe a case of HCM with midventricular obstruction and apical aneurysm formation in 3 patients coming f...

Hemodynamic Consequences of Hypertrophic Cardiomyopathy with Midventricular Obstruction: Apical Aneurysm and Thrombus Formation

BACKGROUND Hypertrophic cardiomyopathy (HCM) with midventricular hypertrophy is an uncommon phenotypic variant of the disease. Midventricular hypertrophy predisposes to intracavitary obstruction and downstream hemodynamic sequelae. CASE REPORT We present a case of HCM with midventricular hypertrophy and obstruction diagnosed after a CT scan of the abdomen incidentally revealed a filling defec...
