Prolonged lead dwell time and lead burden predict bailout transfemoral lead extraction

A “tetra‐axial” system in transfemoral lead extraction

Pacemaker lead extractors must become familiar with transfemoral approaches for lead extraction as a bail-out procedure for a failed superior approach. We presented a "tetra-axial" system for transfemoral lead extraction. This system would be more widely applicable in cases with difficulties in extraction, resulting in more procedural success.

Lead Zinc Extraction Processes

Zinc and lead are the two most widely used non-ferrous metals after aluminium and copper as vital materials in everyday life. They are mined and smelted in many countries in both the developed and developing world. Both pyrometallurgical as well as hydrometallurgical methods are used for production of lead zinc depending on the type of raw material used as a charge. In the pyrometallurgical pro...

Pacemaker and defibrillator lead extraction.

Surgically implanted cardiac devices play an important role in the treatment of heart disease. In the 50 years since the first pacemaker was implanted, technology has improved dramatically, and these devices have saved or improved the quality of countless lives. Pacemakers treat slow heart rhythms by increasing the heart rate or by coordinating the heart’s contraction for some heart failure pat...
