TL;DR: External low‐frequency ultrasound in combination with microbubbles has been reported to recanalize thrombotically occluded arteries in animal models.

Geometric Accuracy of Intravascular Ultrasound Imaging
TL;DR: Variations in blood flow velocity, temperature, eccentric, noncentral catheter placement, and the effect of imaging in different mediums--saline solution, blood, and electrode gel--were studied to assess the potential sources of error of diagnostic intravascular ultrasound imaging.

Noninvasive Transthoracic Low Frequency Ultrasound Augments Thrombolysis in a Canine Model of Acute Myocardial Infarction – Evaluation of the Extent of ST-Segment Resolution
Yochai Birnbaum,Huai Luo,Shaul Atar,Michael C. Fishbein,Andrea V. Brasch,Tomoo Nagai,Dharmendra Pal,Toshihiko Nishioka,Jang-Seong Chae,Claudio Zanelli,Thomas Peterson,Robert J. Siegel +11 more
TL;DR: The combination of tPA with noninvasive transcutaneous delivery of low frequency high-intensity ultrasound resulted in greater resolution of ST-segment elevation when reperfusion occurs and 90 minutes thereafter, as well as a higher rate of angiographic epicardial coronary artery reperfusions.

Hemodynamic Outcomes of Transcatheter Aortic Valve Replacement and Medical Management in Severe, Inoperable Aortic Stenosis: A Longitudinal Echocardiographic Study of Cohort B of the PARTNER Trial

TL;DR: TAVR results in immediate and sustained relief in pressure overload and improved LV systolic function, with continued regression of hypertrophy over 3 years, and is the preferred treatment in eligible inoperable patients.
