@mderdem3 @WilliamZoghbi @DeBakeyCVedu @Sadeer_AlKindi @SachinGoelMD @SLittleMD @NadeenFaza Star ⭐️ Well deserved Saliha and colleagues for this important research effort.

Post call , after hours and some sleepless nights, this is how much this project took 🙂 I am grateful for this recognition by Dr @WilliamZoghbi , Dr @HeartToProve and @DeBakeyCVedu . This would not have been possible without supervision of Dr @Sadeer_AlKindi , thank you 🙏🏻

Hot off the press! My Editorial in JACC on Atrial functional MR. Among 72 definitions of AfMR (!!) in the literature, Koschatko et al demonstrated that the one provided by JACC CV Imaging Expert Panel in 2022 was the most powerful in predicting outcome. pubmed.ncbi.nlm.nih.gov/41949521/

Extremely grateful to share that I matched at @MethodistHosp for Internal Medicine training. Truly thankful to my incredible mentor @almallahmo for his guidance and unwavering support, and to the entire Houston Methodist family for their trust and support. This wouldn’t have been possible without Dr @WilliamZoghbi @HeartToProve @ mahmoudalrifai Excited to continue learning and growing with the Methodist community! #Match2026

Anatomical basis of electrical alternans in cardiac tamponade

Coronary-cameral fistula — complication of septal myectomy

Pulmonary vein Doppler tracks LA–LV hemodynamics beat-to-beat: •S wave → LA relaxation + annular descent (systolic suction) •D wave → LV filling (mirrors mitral E) •Ar wave → atrial contraction (retrograde) Blunted S, dominant D, ↑Ar? → elevated LA pressure & reduced compliance. Simple waveform. High-yield physiology. 🫀

Intracardiac lipoma (dark delineating rim around the mass is a signal cancellation artifact at the interface of fat and water residing protons)

I’m just answering the general gradient vs AVA question. A valve that can potentially result in such load on the myocardium is a pretty sick one. Also, I would use the transvalvular flow rate on resting echo before using the AV calcium score — Very underutilized parameter.

@HeartToProve @echo_stepbystep Right but the myocardium does not consistently feel the PVcs either. A sick heart can also increase SV after a PVC but you wouldn’t use that for their CO. Just food for thought. Perhaps an AV calcium score is the answer here (new ESC guidelines).

Sometimes Dobutamine stress echo is not needed in low-flow low-gradient AS

@DMohananey @echo_stepbystep The question is: does the myocardium “feel” the pressure gradient, or the human made AVA?

@HeartToProve @echo_stepbystep Alright so this is interesting- I have had the same internal debate for some time. Do you also need a post PVC LV VTI? Because if the SV rises to the degree where the AVA is now >1; you would say that is moderate AS if you were doing a DSE.

Intra- and extra- cardiac shunt can coexist. Differentiate mainly via flow pattern not cycle timing. •PFO: transient/intermittent bolus which can be late if RAP>LAP occurs late. •Transpulmonary: continuous trail of bubbles; can occur early for example in liver cirrhosis patients with large stroke volumes.
