Sigmoid ventricular septum treated with endocardial ablation to improve left ventricular outflow: cases report

Frontiers in Cardiovascular Medicine

BackgroundSigmoid Ventricular Septum (SVS) is a type of hypertrophic cardiomyopathy characterized by a reduced angle between the basal interventricular septum and the ascending aorta, and SVS can lead to dynamic Left Ventricular Outflow Tract obstruction (LVOTO) during hypercontractile states.

H/o MI and stents with brief angina has this ED ECG. And what is Fractional Flow Reserve?

Dr. Smith's ECG Blog

A middle-aged man complained of 15 minutes of classic angina that resolved upon arrival to the ED. It is proven better than angiography alone in stable angina , and also has been shown to improve decisions on stenting non-culprit lesions in ACS. Here is his initial ECG: What do you think?

Hypertrophic Cardiomyopathy

All About Cardiovascular System and Disorders

Hypertrophic cardiomyopathy is a genetic disorder with a guarded prognosis which occurs in about 1:500 individuals. The most common symptom of hypertrophic cardiomyopathy is dyspnoea which occurs in 90% of cases and is due to elevated left ventricular diastolic pressures as a consequence of the diastolic dysfunction.

Concerning EKG with a Non-obstructive angiogram. What happened?

Dr. Smith's ECG Blog

The commonest causes of MINOCA include: atherosclerotic causes such as plaque rupture or erosion with spontaneous thrombolysis, and non-atherosclerotic causes such as coronary vasospasm (sometimes called variant angina or Prinzmetal's angina), coronary embolism or thrombosis, possibly microvascular dysfunction.

"A patient just arrived as a transfer for NSTEMI."

Dr. Smith's ECG Blog

Given her lack of risk factors for coronary disease, and the fact that she was a 53 year old woman with compatible history and echo findings, stress cardiomyopathy rose to the top of my differential. Of course, stress cardiomyopathy is a diagnosis of exclusion. But it is a diagnosis of exclusion.

Dynamic, Reversible, Ischemic T-wave inversion mimics Wellens'. All trops negative.

Dr. Smith's ECG Blog

This appears to be a classic Wellens' ECG, Pattern A, with terminal T-wave inversion in V2-V4, preserved R-waves, and it appears to be Wellens' syndrome, as it occurred after resolution of typical angina pain. When this happens, troponins are negative, there is no wall motion abnormality, and it is true unstable angina.
