Mortality in hypertrophic cardiomyopathy – Cardiology MCQ – Answer
Disease specific mortality in hypertrophic cardiomyopathy – Correct answer: a) 0.5% per year
Hypertrophic cardiomyopathy (HCM) is the commonest among heritable heart diseases, with prevalence of about one in 500 individuals [1]. HCM is often highlighted as the leading cause of sudden death in young adults and athletes [2].
Still the absolute annual mortality in HCM is not high with availability of current treatment modalities including the implantation of cardioverter-defibrillator to prevent sudden death. It has been reported t...

5 steps to improve your diastolic dysfunction of life
I recently attended a cardiology conference where a dear friend of mine was presenting on the topic of hypertrophic cardiomyopathy. She discussed how fibrosis within the ventricle causes diastolic dysfunction, an inability of the myocardium to relax. My ears perked up. Just the week before, while on vacation, I personally experienced the inability to relax. […]Find jobs at Careers by KevinMD.com. Search thousands of physician, PA, NP, and CRNA jobs now. Learn more.

A 50-something Australian with sudden severe epigastric and chest pain presented looking extremely ill.
A 50-something with sudden severe epigastric and chest pain presented looking extremely ill.Here is her ECG:What do you think?There is ST Elevation in V2-V6, worrisome for ischemia.Or is it?Notice the very large R-waves and the very prominent J-point notching, with small S-waves.This is typical ofBenign T-wave Inversion, which is commonly seen in black patients of African heritage.This case was sent from Australia and the patient was aboriginal. I have never heard of or seen benign T-wave inversion in Australian aboriginal blacks.The cath lab was activated and the patient was taken for angiogram, which was norma...

Ischemic cardiomyopathy: Why is it, still searching for a definition?
The term Ischemic cardiomyopathy(ICM) was originally coined by Dr. Burch from Tulane University, New Orleans, USA in 1970. For many decades there was skepticism regarding the existence of such entity. WHO classification over the years never included this term. ESC working group of 2008 (Elliott P, European Heart 29(2):270–276) decided not to include CAD as a cause for cardiomyopathy. Even the current MOGES system doesn’t invoke CAD as a cause for cardiomyopathy. But, I am sure, most of practicing cardiologists would agree, there is a need for such an entity.
Why there is much reluctance to diagnose Ische...

Do you recognize these ECGs? STEMI? LVH? What?
What do you think of these ECGs?I came across the first one reading it blind for a study. I was certain I knew the diagnosis, and went to the chart to confirm.The first 3 were recorded on one day.ECG 1:ECG 2:ECG 3:ECG 4, recorded 12 days later:These ECGs are classic for abenign variant in Black males. I was certain it would be a relatively young black male without cardiac pathology.Result from chart:It was a black male in his 40s.The first ECG, and then the next two (1-3), were recorded for chest and abdominal pain. The patient was ultimately diagnosed with biliary colic.The patient ruled out for MI by se...

Assessing SCD risk in HCM by CMR
Sudden cardiac death (SCD) is one of the dreaded complications of hypertrophic cardiomyopathy (HCM) and predicting it is always challenging. Clinical risk stratification algorithms lack good sensitivity and specificity. Myocardial disarray has been well documented in those who died suddenly with HCM. Cardiac magnetic resonance imaging with a novel technology known as diffusion tensor cardiac magnetic resonance (DT-CMR) is a promising way for in vivo demonstration of myocardial disarray [1].
DT-CMR can visualise myocardial microstructure by mapping the diffusion of water molecules. But it is technically challenging and ac...

LVOT Obstruction
IVS (interventricular septum) is hypertrophied and bulges into the left ventricular outflow tract (LVOT), narrowing it. Gradient across the LVOT is increased to 26 mm Hg, as seen in the lower image with continuous wave (CW) Doppler. Overall features suggest hypertrophic obstructive cardiomyopathy (HOCM).

15 yo AAM with ST Elevation and T-wave Inversion. Hypertrophic Cardiomyopathy or Normal ( " Variant " )?
Is this normal or hypertrophic cardiomyopathy (HOCM)?The mother of a 15 yo African American male brought her son to the clinic for a sports physical. There was a family history of sudden death. The clinic recorded this ECG and was alarmed:Should the physician be alarmed by this?Answer: No.This is almost certainly a normal ECG in an African American adolescent male. There is some remote possibility of HOCM, but the morphology is classic for anormal variant. Even calling it a normal variant is an ethnocentric terminology, as if the white normal is the true normal. This is normal normal for an Af...

Two cases of ST Elevation with Terminal T-wave Inversion - do either, neither, or both need reperfusion?
Written by Pendell Meyers with edits by Steve SmithI was sent these 2 ECGs with no clinical information other than chest pain:Do either or both of these ECGs show ischemic changes? If so, what should you do and why?Let ' s take them one at a time.What would your response be?I responded: " Awesome classic benign T wave inversion! That ' s the patient ' s baseline normal variant. ... But if it were a good story with exertional syncope or something you ' d have to treat it like it could be HOCM, etc. Tell me more.

MKSAP: 56-year-old man with a family history of hypertrophic cardiomyopathy (HCM)
Test your medicine knowledge with the MKSAP challenge, in partnership with the American College of Physicians.
A 56-year-old man is being evaluated after his 18-year-old son had a syncopal episode during a high school basketball game and was diagnosed with hypertrophic cardiomyopathy (HCM). The patient has had no symptoms, including with physical activity such as golfing or playing tennis. Medical history is unremarkable, and a review of family history is negative for other relatives with HCM, sudden cardiac death, or tachyarrhythmias. He takes no medications.
Findings of a comprehensive physical examination are unremark...

LVOT gradient in HOCM – Doppler echocardiogram
LVOT gradient in HOCM – Doppler echocardiogram
Left ventricular outflow tract gradient in hypertrophic obstructive cardiomyopathy
Left ventricular outflow tract gradient (LVOT) in hypertrophic obstructive cardiomyopathy (HOCM) is usually measured from the apical five chamber view (apical 5C) in echocardiography. Initially the apical 5C view is obtained and then the colour Doppler flow mapping (CFM) is done to locate the flow in LVOT. Continuous wave (CW) Doppler cursor is then aligned along the LVOT colour jet of HOCM. The CW jet in HOCM is described as dagger shaped or sickle shaped, unlike the symmetrical tongue ...

M-mode echocardiogram in left ventricular dysfunction
M-mode echocardiogram in left ventricular dysfunction
M-mode echocardiogram is commonly used to measure left ventricular dimensions and ejection fraction. Ejection fraction is indicative of the left ventricular systolic function. In this case left ventricular systolic function is grossly depressed, with a left ventricular ejection fraction (EF) of only 31.1%. Usually the left ventricular cavity is also significantly dilated when there is severe left ventricular dysfunction. But here it is within the normal range. IVSd: Interventricular septal septum, diastolic; LVIDd: Left ventricular internal diameter, diastolic; LVPWd: ...
