Another Way Antibiotic Therapy Can Kill You
An analysis revealed fluoroquinolone antibiotic use was associated with later aortic diseases and mortality in patients without known aortic disease.

STEMI in Post-Transcatheter Aortic Valve Replacement Patients
This large series of post-transcatheter aortic valve replacement patients with ST-elevation myocardial infarction demonstrates elevated rates of percutaneous coronary intervention failure and high short- and intermediate-term mortality rates.

Using His Bundle Pacing for Cardiac Resynchronization: Does It Hold Up to the Standard?
In a randomized trial of patients with heart failure and left bundle branch block, cardiac resynchronization therapy via permanent His bundle pacing produced similar short-term outcomes to traditional biventricular pacing, albeit with higher pacing thresholds.

Can Mitral Regurgitation Prevent Atrial Thrombosis Caused by Atrial Fibrillation?
A study of nonrheumatic patients with atrial fibrillation who were inadequately or not anticoagulated undergoing transesophageal echocardiography before cardioversion showed moderate-to-severe mitral valve regurgitation attenuates the risk of finding left atrial thrombi or spontaneous echo contrast and could be considered a thromboembolic risk modifier.

Is a History of Palpitations Useful for Detecting Atrial Fibrillation?
An analysis of the utility of implanted loop recorders to detect subclinical atrial fibrillation in high-risk individuals showed that among common arrhythmia-compatible symptoms, only palpitation was predictive of discovering episodes of atrial fibrillation.
