Valve-in-Valve TAVR for Failed Surgical Prostheses: Short-Term Advantages, Long-Term Unknowns
This large retrospective study of patients undergoing reintervention for failed bioprosthetic aortic valves showed better short-term outcomes with valve-in-valve transcatheter aortic valve replacement vs. redo surgical aortic valve replacement.

Who Benefits from Primary Prevention ICDs?
Long-term follow-up of SCD-HeFT did not show any benefit in installing implantable cardioverter-defibrillator devices in patients with New York Heart Association class III symptoms or nonischemic cardiomyopathy.

Achieving AV Synchrony Without Wires
In the MARVEL 2 prospective study of patients with atrioventricular block treated with a leadless ventricular pacemaker, atrial sensing via an accelerometer-based algorithm was largely successful in establishing atrioventricular synchronous pacing.

What to Do with Large Pericardial Effusions
An observational study of patients with chronic, large, hemodynamically insignificant, C-reactive protein-negative, idiopathic pericarditis in which the majority were treated by pericardiocentesis or surgical drainage showed most patients treated conservatively remained stable. The invasive approach did not reveal an etiology for the effusions.

Is Isolated Diastolic Hypertension a Disease?
An analysis of three large prospective databases showed the 2017 American College of Cardiology/American Heart Association revised definition of isolated diastolic hypertension as > 80 mmHg rather than the previous definition of > 90 mmHg resulted in a 5% higher prevalence of diastolic hypertension. This was not significantly associated with cardiovascular disease outcomes.
