Variations of the radial artery, however, could impede the cardiac catheterization and pose significant challenges to the interven-tional cardiologist. Herein, we report a failure of transradial heart catheterization due to high-bifurcating hypoplastic radial artery.

Research paper thumbnail of A Case of Acute Left Main Coronary Obstruction Following Transcatheter Aortic Valve Implantation

Coronary occlusion is a periprocedural life-threatening complication that despite its low frequency (˂1%) is poorly predictable and requires immediate diagnosis and treatment. Herein, we report a coronary obstruction after transcatheter implantation of valve prosthesis, followed by coronary intervention with successful recanalization.

The retrospective study included 549 patients, hospitalized with STEMI in St. Ekaterina University Hospital (age - 62.66±12.56; women - 31.3%) from 01.06.2008 to 30.06.2011. One-vessel disease was found in 232 patients (44%) as compared to two-vessel disease in 165 patients - 31% and multivessel disease in 130 patients - 25%. There was LM stenosis (>30) in 11 patients (2%); ostial lesion in 33 patients (6.3%); presence of Ca in 37 patients (7%). A stent was implanted in 484 patients (91.8%), and GP IIb/IIIa was used in 400 patients (75.9%). There was significant increase in mortality rates in patients with multivessel disease: 15.6% - 46 patients, compared to one-vessel disease - 6.5% (15 patients) (p<=0.01). Both early (30 days) and late mortality (one year) rates were higher in the multivessel group ...
