4 Major Types of Hypertrophic Heart Diseases
HTN Heart Disease, Hypertrophic Cardiomyopathy, Aortic Stenosis, Cor Pulmonale
3 Characteristics of HTN HD
Diastolic Dysfunction, Impaired Compliance and Ventricular Filling
4 major types of Hypertrophic Heart Diseases in order or prevalence
HTN Heart Disease, Hypertrophic Cardiomyopathy, Aortic Stenosis, Cor Pulmonale
Acute-on-Chronic Cor Pulmonale =
RV Dilatation + Hypertrophy
Age of presentation with Calcifications in Sinuses of Valsalva
Over 70
Age range for Bicuspid Aortic Stenosis
young and middle-aged adults
Age range for Degenerative Calcific Aortic Stenosis
> 70
Age range for Rheumatic Aortic Stenosis
young and middle-aged adults
Chronic Cor Pulmonale is characterized by
RV (and often R atrial) Hypertrophy
Criteria for Dx of HTN HD
LV Hypertrophy in absence of other CV pathology; Hx or pathologic evidence of HTN
Diastolic Dysfunction, Impaired compliance and Ventricular Filling are characteristic of
HTN HD
Dilation in HTN HD
Usually doesn’t occur until late in process
Do the same tx’s for atherosclerosis prevention work for calcific aortic stenosis
NO
Fibrosis is a feature of
HCM
Fibrosis of HCM can provide the anatomical substrate for
Reentrant Ventricular Tachycardia
How does rheumatic vavlulitis stenose the semilunar valve
Inflammation and fibrosis start at the commissure and moves inward
Hypertrophic CM is associated with asymmetric __
hypertrophy of septum
If aortic valve stenosis is due to previous rheumatic valvulitis, 95% of cases have simultaneous
mitral stenosis
In Acute Cor Pulmonale, the RV usually shows only
Dilation
In some cases of what are myocytes oriented in abnormal directions (not parallel)
HCM
Microscopic findings in HTN HD
Transverse diameter of myocytes is increased; Boxcar nuclei
Myocyte disarray is seen in many cases of
Hypertrophic CM
Normal LV thickness
1.2 - 1.4 cm
Normal Ventricular wall thickness
1.2 - 1.4 cm
