However, the prognostic significance of frequent PVCs in asymptomatic patients with a normal LV function is unclear. Methods: Two hundred and thirty-nine consecutive patients presenting with frequent ...

This is also associated with a better left ventricular filling and systolic function after surgery. The dilemma of when to treat patients with free pulmonary incompetence, presenting late after repair ...

The Harmony TPV25 transcatheter pulmonary valve (Medtronic Inc.) is constructed with a self-expanding stent frame comprising six zigged nitinol wires sewn together and covered with knitted polyester ...

The authors discuss the mechanisms, clinical presentation, and evaluation of right ventricular failure, as well as its management.

This video presents a practical method for conducting visual, semiquantitative assessment of right ventricular size and systolic function with focused cardiac ultrasonography.

LVOT = left ventricular outflow tract; MR = mitral regurgitation. Doppler echocardiography at rest: Trace mitral regurgitation (MR), no MR signal; left ventricular outflow tract (LVOT) velocity 2 ...

Introduction Ventricular arrhythmias (VAs) are one of the most common arrhythmias encountered in clinical practice. VAs with left bundle branch block and inferior axis morphology frequently originate ...

Background: Patients with premature ventricular contractions (PVCs) from the right ventricular outflow tract (RVOT) and apparently normal hearts, can have ST elevation similar to type 2 or type 3 ...

Identifying the site of origin (SOO) of outflow tract ventricular arrhythmias (OTVAs) is key to plan radiofrequency ablation procedures. Currently, electrophysiologist try to extract that information ...

BackgroundThe effects of right ventricular apical pacing (RVAP) and right ventricular outflow tract (RVOT) septal pacing on atrial and ventricular electrophysiology have not been thoroughly compared.
