60-something y/o male patient who isn’t physically active but does ADLs. Scheduled for CABG but has AI, PVD, EF 40%, HTN, HLD. Would you suggest an AVR or not…. along with the CABG?
What would you suggest?

Transthoracic echo: a beginner’s guide #tte #cardiac #echo #meded
Knowing how to do a quick focused echo exam can be instrumental in diagnosis as well as treatment. This has helped me determine how severe cardiac tamponade has been in an emergent case prior to induction when there was no prior echo. There are so many more useful answers that a bedside echo can provide. Time to get acquainted.

Mitral Stenosis on TEE
Sometimes you need a refresher on measurements of the mitral valve via TEE. Here’s a great 2D TEE walk through for mitral stenosis.

HeartWare vs. HeartMate LVAD
A couple of weeks ago, I took care of a patient who desperately needed to get better from acute CHF. At that time, we placed the patient on an impella… but the next day, it was deemed that he needed ECMO to reperfuse his organs. After a week on ECMO with continued impella support, ECMO was titrated down and off while maintaining 3.9L/min flow from the impella. During the wean off ECMO, the patient had been extubated and was mentating clearly and interacting appropriately.
Fast forward a couple days after getting extubated, the patient was ripe for an LVAD. But which one? (We ended up placing the patient on HeartWare LVAD).

HeartMate II
Summary
- Cost-effectiveness: HeartWare > HeartMate II (UK NHS study, April 2014)
- LV Geometry: HeartWare = HeartMate II (J CT Surg, 2013)
- Stroke & GI bleed risk: HeartWare > HeartMate II (J Card Surg 2013)
- Risk of device failure: HeartWare < HeartMate II
- ENDURANCE trial: Randomized patients eligible for DT 2:1 to the HeartWare centrifugal flow LVAD versus the HeartMate II axial flow LVAD. The trial did reach its primary noninferiority endpoint of stroke free survival at 2 years (55.0% in the HeartWare patients versus 57.4% in the HeartMate II patients). Of note, a change in the design of the HeartWare device during the trial (sintering of the inflow cannula) appeared to decrease the incidence of pump thrombosis. Overall, the stroke rate was higher in the HeartWare arm whereas device malfunctions requiring exchange or urgent transplantation were more common in the HeartMate II arm. Data analysis suggested that better blood pressure control in the HeartWare arm may decrease the stroke rate and a second cohort of patients is being enrolled with more attention being paid to blood pressures management.
- ROADMAP study: (Risk Assessment and Comparative Effectiveness of Left Ventricular Assist Device and Medical Management in Heart Failure Patients) was an observational study of the Thoratec HeartMate II LVAD compared to optimal medical management in patients with advanced heart failure. Thirty day mortality was the same in both groups (1%) while one year survival was 80% in the LVAD group compared to 64% in the medical group (on an as treated basis). Functional status and quality of life improved significantly more in the LVAD group (analyzed by 6 minute walk, health related quality of life, and NYHA class). Unfortunately, adverse events in the LVAD group remained similar to what was previously reported in the DT trial, with bleeding being the most frequent adverse event.
