TL;DR: Two-dimensional transthoracic echocardiography showed hypertrophy of the left ventricle, mid-ventricular obstruction and an apical aneurysm and color-flow imaging at the obstruction site on the apical four-chamber view demonstrated systolic flow reversal in addition to a paradoxical jet flow.

Abstract: A 69-year-old man presented to our hospital with chest pain. Two-dimensional transthoracic echocardiography showed hypertrophy of the left ventricle, mid-ventricular obstruction and an apical aneurysm. Color-flow imaging at the obstruction site on the apical four-chamber view demonstrated systolic flow reversal in addition to a paradoxical jet flow. The systolic flow reversal may have been caused by a decreased apical contractility and pressure during systole.

TL;DR: A 93-year-old woman was transferred to our hospital for lightheadedness. Transthoracic apical four-chamber echocardiography showed a large apical aneurysm and paradoxical flow as mentioned in this paper .

Wall stress and patterns of hypertrophy in the human left ventricle.
TL;DR: The hypothesis that hypertrophy develops to normalize systolic but not diastolic wall stress is suggested, and it is proposed that increased syStolic tension development by myocardial fibers results in fiber thickening just sufficient to return the systolics stress (force per unit cross-sectional area) to normal.

TL;DR: Patients with left ventricular apical aneurysms represent an underappreciated subset in the heterogeneous HCM disease spectrum with important clinical implications, often requiring a high index of suspicion and cardiovascular magnetic resonance for identification.

Mid-Ventricular Hypertrophic Obstructive Cardiomyopathy : Presenting with Acute Myocardial Infarction
TL;DR: The case of a patient who presented with ventricular fibrillation, ST-segment elevation on electrocardiography, and cardiac-enzyme elevation, in the presence of normal coronary arteries is reported, showing an hourglass appearance of the left ventricle with an aneurysm in the apex.
