Left ventricular scar impact on left ventricular synchronization parameters and outcomes of cardiac resynchronization therapy.

Background: Left ventricular scar, including global scar and lateral wall, plays an important role in predicting response to cardiac resynchronization therapy (CRT).

Materials And Methods: Thirty patients underwent CRT implantation. Assessment of left ventricular (LV) dyssynchrony was done through Gated SPECT LV phase analysis.

Potential pro-arrhythmic effect of cardiac resynchronization therapy.

Unlabelled: A decline in mortality due to pump failure has been clearly documented after cardiac resynchronization therapy (CRT), however the impact on sudden cardiac death and the development of malignant ventricular arrhythmias remains questionable. Our study aims to investigate this alleged pro-arrhythmic effect of CRT using surface electrocardiogram (ECG) markers of pro-arrhythmia.

Methods: Seventy five patients, who received CRT were included in this study.

Early experience with a new approach for percutaneous intervention of totally occluded saphenous vein graft: is the flow the best thrombolytic?

Aims: Percutaneous coronary intervention (PCI) in the total occlusion of aged saphenous vein grafts (SVGO) is difficult because of inadequate dilatation and distal embolisation. The aim of this study is to report the early experience and clinical outcome of SVGO PCI with a multistaged procedure.

Methods And Results: Between January 2003-2006, we treated 20 consecutive patients (pts) admitted with the diagnosis of non-ST segment elevation acute coronary syndromes with culprit lesion located in SVGO.
