The carina angle-new geometrical parameter associated with periprocedural side branch compromise and the long-term results in coronary bifurcation lesions with main vessel stenting only.

Background: The two main problems unresolved in coronary bifurcation stenting are periprocedural side branch compromise and higher restenosis at long term. The purpose of this study is to reveal the link between periprocedural side branch compromise and long-term results after main vessel stenting only in coronary bifurcations.

Methods: Eighty-four patients formed the study population.

[Spinal cord stimulation in refractory angina pectoris -- a case description].

Spinal cord stimulation (SCS) is one of the methods for treating angina pectoris and has been used since 1985. Patients with refractory angina pectoris despite optimal medication and revascularisation procedures are suitable for the SCS. This kind of treatment is not common in Poland.
