Takotsubo Stress Cardiomyopathy, with Echocardiogram

Dr. Smith's ECG Blog

SCM may happen from a wide variety of psychological or physiological stresses, including respiratory failure (although in this case a psychological stress led to poor myocardial function and then pulmonary edema, then respiratory failure) and intracranial bleeding. The apparent trigger was stress from losing custody of children.

Development and Evaluation of a Deep Learning–Based Pulmonary Hypertension Screening Algorithm Using a Digital Stethoscope

Journal of the American Heart Association

GradCAM++ technique highlighted physiologically meaningful PCG segments in example pulmonary hypertension recordings.ConclusionsWe demonstrated the feasibility of using digital stethoscopes in conjunction with deep learning algorithms as a lowcost, noninvasive, and easily accessible screening tool for early detection of pulmonary hypertension.

Abstract TMP39: Paucity of Evidence-Based Patent Foramen Ovale Severity Ratings in Transesophageal Echocardiogram Clinical Reports

Stroke Journal

Introduction:The presence of a large physiologic shunt, defined as >20 left atrial microbubbles within 3 cardiac cycles on transesophageal echocardiography (TEE), is a key, randomized controlled trial-validated, indication for patent foramen ovale (PFO) with a closure device in patients with otherwise cryptogenic ischemic stroke.

Case Report: Multimodality evaluation and clinical management of a single coronary artery

Frontiers in Cardiovascular Medicine

The echocardiogram showed normal cardiac structure and function, however, there was a concern for possible anomalous origin of the left coronary artery. A 14-year-old male with no significant medical history presented with intermittent palpitations for 2–3 months that occurred at rest and were associated with light-headedness.

Abstract 4134456: Hybrid Cardiac Targeting Peptide Ameliorates HFpEF Phenotype in Mice

Circulation

After 5 weeks of the diet, HFD mice and their littermate controls underwent baseline exercise testing and echocardiograms. Echocardiograms were performed under 1.5% inhalational isoflurane. Gene and protein expression studies in heart tissue are underway. Further work is warranted with a larger sample size.

Abstract 4123391: CardioMEMS and Mavacamten: A Synergistic Approach in Managing Hypertrophic Obstructive Cardiomyopathy with HFpEF Phenotype

Circulation

However, surgery was deferred because of decompensated HFpEF, as evidenced by significant leg edema on exam, and severely elevated left and right-side filling pressure, with restrictive physiology on right heart catheterization. LVOT obstruction resolved on follow up echocardiogram.
