Impact of Percutaneous Intervention Compared to Pharmaceutical Therapy on Complex Arrhythmias in Patients With Chronic Total Coronary Occlusion. Rationale and Design of the CTO-ARRHYTHMIA Study.

Chronic total coronary occlusions (CTO) occur in up to 50 % of patients with coronary artery disease by angiography. In CTO-patients, clinically significant arrhythmia is potentially important and insufficiently investigated. Therefore, the purpose of the CTO-ARRHYTHMIA study was to investigate the incidence of loop recorder detected clinically significant arrhythmias and the effect on arrhythmias of revascularization by CTO-PCI.

Quality of life following renal sympathetic denervation in treatment-resistant hypertensive patients: a two-year follow-up study.

. Hypertension is a significant health burden. In the last 10 years, renal sympathetic denervation has been tested as a potential treatment option for a select group of patients with treatment-resistant hypertension.

Coronary artery disease cannot be reliably evaluated by 16-slice multidetector spiral computed tomography.

Objectives: Angiography by selective catheterization is the standard method for coronary artery imaging but carries a risk of rare, but serious complications. We investigated whether 16-slice multidetector spiral computed tomography (MDCT) could substitute for selective angiography for evaluation of coronary artery disease in surgically revascularized patients.

Design: In a setting closely resembling routine clinical practice, 45 patients who had been operated with coronary artery bypass grafting 508-1135 (mean 811) days before were examined with MDCT and conventional selective angiography on the same day.

Coronary bypass graft patency cannot be determined by multidetector spiral computed tomography.

Objectives: Angiography by selective catheterization is the reference standard for coronary bypass graft patency assessment but carries a risk of serious complications. We have investigated whether 16-slice multidetector spiral computed tomography (MDCT) can substitute for selective angiography.

Design: Two to three years after coronary artery bypass grafting, 45 patients with a total of 156 bypasses (100 single and 28 sequential grafts) were examined with both MDCT and conventional selective angiography on the same day.
