Paradoxical systolic and diastolic flow abnormalities in hypertrophic cardiomyopathy with mid-cavity systolic obstruction.
Systolic obstruction of the left ventricular outflow tract, either at rest or during provocation, is a frequent finding in patients with hypertrophic cardiomyopathy. Mid-cavity obstruction is uncommon, and intraventricular diastolic pressure gradients in association with either mid-cavity of apical hypertrophy are reported only rarely. We describe a patient with hypertrophic cardiomyopathy with...
متن کاملHypertrophic cardiomyopathy and diastolic dysfunction.
Hypertrophic cardiomyopathy (HCM) is a disease state with characteristic pathologic changes most likely to result in abnormalities of diastolic function. Indeed, HCM may well be considered a “poster child” for diastolic dysfunction, because pronounced ventricular hypertrophy is associated with a reduced left ventricular (LV) cavity. The pressurevolume relationship would almost certainly be shif...
متن کاملSystolic Heart Failure in a Patient With Hypertrophic Obstructive Cardiomyopathy
• Percutaneous transluminal septal myocardial ablation and surgical myectomy are good options for patients who do not respond to medications. CASE STUDY LB,a 61-year-old man, well known in our cardiology practice, came to the emergency department early one morning after experiencing 24 hours of profound weakness and increasing dyspnea out of proportion to his usual shortness of breath. He had a...
متن کاملSystolic and diastolic mechanics in stress cardiomyopathy.
BACKGROUND Stress cardiomyopathy (SCM) is a peculiar form of reversible left ventricular dysfunction seen predominantly in women and occurs in response to emotional or physical stress. Because dysfunction in SCM is reversible and that of acute myocardial infarction (MI) is not, we hypothesized that these fundamental mechanistic differences between SCM and MI would be associated with different s...
متن کاملDelineation of Systolic and Diastolic Heart Murmurs via Wavelet Transform and Autoregressive Modeling
This paper describes a signal processing algorithm that utilizes wavelet transform and autoregressive modeling to identify heart sounds and to generate clinical features that characterize systolic and diastolic heart murmurs. A wavelet transform (WT) based on the Daubechies wavelet was adopted to facilitate the identification of the first and second heart sounds (S1 and S2) and to isolate systo...
