Twiddling in cardiac resynchronization therapy: 'when length matters'.
نویسندگان
چکیده
We report on a 75-year-old woman who successfully underwent cardiac resynchronization therapy. Two weeks after implantation, right continuous pectoral stimulation appeared. Retraction and dislodgement of the right atrial and right ventricular leads as well as coiling of the three leads around the device generator were observed on chest radiography, but, surprisingly, the left ventricular lead remained unaffected due to its major length to facilitate the manoeuvers of implantation.

[Cardiac resynchronization therapy: when the pacing site really matters].
Cardiac resynchronization therapy has been one of the major qualitative advances made in the treatment of heart failure in recent decades, and it strongly underlines the relationship between heart mechanics, hemodynamic function, and electrophysiology. Since the 1980s a number of clinical and experimental studies have shown that abnormalities in intraventricular conduction, associated or not wi...
متن کاملCardiac resynchronization therapy improves heart rate variability in patients with symptomatic heart failure.
BACKGROUND Cardiac resynchronization therapy (CRT) using biventricular pacing improves symptoms and functional capacity in patients with moderate to severe heart failure. The present study examined whether an improvement in ventricular performance from resynchronization therapy changes the autonomic control of heart rate. METHODS AND RESULTS Heart rate variability (HRV) was examined in 50 pat...

We describe the case of a 37-year-old woman who presented with complete right bundle branch block and right axis deviation. She was admitted to our hospital due to severe heart failure and was dependent on inotropic agents. Cardiac resynchronization therapy was initiated but did not improve her condition. After the optimization of the pacing timing, we performed earlier right ventricular pacing...
متن کاملCardiac resynchronization therapy for congestive heart failure.
Cardiac resynchronization represents a novel therapeutic strategy for the treatment of congestive heart failure due to systolic dysfunction. Since its modest beginnings in the 1990s, cardiac resynchronization therapy has gained widespread acceptance as a useful adjunct to pharmacologic therapy for congestive heart failure. Randomized trials have consistently shown functional improvement in pati...
متن کامل[Three-dimensional imaging in cardiac resynchronization therapy].
Cardiac resynchronization therapy improves clinical symptoms and prognosis of heart failure patients. However, it has been shown that up to 40% of patients do not respond to this therapy. Three main determinants of cardiac resynchronization therapy response have been identified: left ventricular dyssynchrony, left ventricular lead position, and extent and location of myocardial scar tissue. Two...
