Hybrid Approach for the Treatment of Superior Vena Cava Syndrome Induced by Pacemaker.

Pacemaker-induced superior vena cava syndrome (SVCS) is a rare but incapacitating adverse event that can occur years after implantation. Inasmuch as it is a rare disease, there is no consensus about its treatment. The most widely used option is balloon angioplasty and venous stent implantation, with preservation of the lead or previous extraction and subsequent reimplantation after the procedure, which is associated with new episodes of thrombosis.

Which type of valve should we use in tricuspid position? Long-term comparison between mechanical and biological valves.

Background: Nowadays, tricuspid valve replacement (TVR) is much less common than aortic or mitral valve replacement, since repair is almost always preferable. Prosthetic tricuspid valves are associated with high mortality and morbidity, mostly due to thrombotic or hemorrhagic events. Nevertheless, there is lack of evidence of which is the optimal type of valve (biological versus mechanical) in tricuspid position.

Selecting the best site for pacing leads after cardiac surgery by evaluating the asynchrony of myocardial deformation observed with different pacing sites.

Introduction And Objectives: After cardiac surgery, temporary pacing leads are routinely implanted in the right ventricle (RV). The objective was to investigate the effect of different ventricular pacing locations on cardiac synchrony (by evaluating myocardial deformation, or strain) and efficiency in patients undergoing cardiac surgery.

Methods: Interventricular asynchrony (i.
