Article Synopsis
- Venous obstructions are common in patients with transvenous leads, particularly after lead replacement or upgrade procedures, but little evidence has been reported on their clinical impact.
- A study involving 84 patients revealed that 32.6% experienced complications after surgery, with 28.6% developing upper extremity deep venous thrombosis (UEDVT) and 7.1% having pulmonary embolism (PE).
- The study identified significant risk factors for UEDVT, including severe collateral circulation and transvenous lead extraction, indicating a need for further research on preventive measures for these patients.
Background: Estimative of left ventricular ejection fraction (LVEF) is a major indication for echocardiography. Speckle tracking echocardiography (STE) allows analysis of LV contraction mechanics which includes global longitudinal strain (GLS) and twist/torsion, both the most widely used. Direct comparison of correlations between these novel parameters and LVEF has never been done before.

Therefore, the development and evolution of this CMP has always been a major topic in numbers of previous studies. A comprehensive echocardiographic study of left ventricular (LV) mechanics, fully assessing myocardial contraction, has never been done before.

Methods: From January 2000 to June 2003, we retrospectively evaluated patients who underwent EA-DSE for known or suspected coronary artery disease. We studied 494 patients, 243 men and 251 women, who were not under beta-blocker or calcium channel-blocker therapy (Group A) and 326 patients, 157 men and 169 women, using these medications (Group B).
