Age-dependent clinical and echocardiographic manifestations of aortic stenosis in an unselected, non-biased cohort.

Background: Age, clinical presentation and echocardiographic parameters are important factors in the decision on an individualized therapeutic strategy for patients with aortic stenosis (AS). Less is known about this information in a non-selected non-biased cohort.

Methods: We performed a retrospective, systematic analysis of patients admitted to our hospital from 1/1/2014 to 1/6/2018 with the diagnosis of AS.

Hemodynamics and prognosis after primary cardiac resynchronization system implantation compared to "upgrade" procedures.

Introduction: Left bundle brunch block (LBBB) and right ventricular stimulation (RVS) may be associated with asynchrony and heart failure. Differences between these two entities and their response to cardiac resynchronization therapy (CRT) are not well defined.

Methods: Patients receiving CRT from 1999 to 2006 were analyzed for cardiac events and prognosis separated between primary implants for LBBB (n = 221) and upgrades from RVS (n = 107).

Reversing cardiac resynchronization therapy non-responder status in a patient with a surgically placed epicardial left ventricular lead by switching to an active fixation coronary sinus lead.

This report describes the reversal of a cardiac resynchronization therapy non-responder status in a patient with a surgically placed left ventricular lead by the use of a newly available active fixation coronary sinus lead.

Coronary sinus lead fragmentation 2 years after implantation with a retained guidewire.

Cardiac Resynchronization therapy (CRT) using coronary sinus (CS) leads is an established method for the therapy of congestive heart failure (CHF) in the case of inter- and intraventricular conduction delays. However implantation of CS leads is somewhat challenging due to a high number of peri- or postoperative dislocations at a rate of about 10%. The retained guidewire technique has been proposed for the implantation of coronary sinus leads for stabilization in case of repetitive intraoperative dislocations.
