Functional assessment of coronary artery disease in patients with severe aortic stenosis: a review

Heart BMJ

A significant proportion of patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI) have concomitant coronary artery disease (CAD). A better understanding of how we assess and interpret coronary physiology in these patients is required to optimise treatment pathways.

A NOTIONal truth : Surgical AVR deteriorates faster than TAVI, for some mysterious reasons!

Dr. S. Venkatesan MD

The surprise however is, TAVI was superior to cardiac surgeons in multiple aspects.The mysterious finding is TAVI had less Structural valve dysfunction , and possibly low bio valvular failure (BVF), if Kaplan -Myer curve trend is little extrapolated. No doubt ,the Aortic interventional world is applauding and everyone is joining the party.

Magenta Medical, Developer of World’s Smallest Heart Pump, Closes $105M Financing Round

DAIC

The pump is delivered into the heart fully sheathed, over a guidewire, through the aorta, and across the aortic valve. It further notes the following on the technology: The Elevate pump is first folded and then inserted percutaneously through a small puncture in the groin to accommodate a commercially available 10 Fr introducer sheath.

Learning some crucial cardiovascular hemodynamic lessons* from Giraffe 

Dr. S. Venkatesan MD

An Aortic Impella device, that is distal to the aortic valve and devoid of LV-related issues. The hemodynamic of the Giraffe’s vascular system is a good physiologic model of circulation, that defy gravity. Shall we think about,axial pumps in ascending Aorta in series with LV.

Diffuse Subendocardial Ischemia on the ECG. Left main? 3-vessel disease? No!

Dr. Smith's ECG Blog

Look at the aortic outflow tract. The diagnostic coronary angiogram identified only minimal coronary artery disease, but there was a severely calcified, ‘immobile’ aortic valve. Aortic angiogram did not reveal aortic dissection. If you see this, you should Doppler the valve. What do you see?

A young woman with palpitations. What med is she on? With what medication is she non-compliant? What management?

Dr. Smith's ECG Blog

Written by Pendell Meyers A woman in her 20s with connective tissue disorder and history of aortic root and valve repair presented with palpitations. Further history revealed she had new onset atrial flutter soon after her aortic surgery, and was put on flecainide approximately 1 month ago. Atrial flutter with 2:1 conduction.
