Treating Refractory Hypertension: Renal Denervation With High-Resolution 3D-Angiography.

A 53-year-old male was referred to our Department for refractory primary hypertension. Despite high doses of 6 anti-hypertensive drugs, ambulatory monitoring of blood pressure (BP) revealed a mean BP of 160/90 mmHg. Under local anaesthesia, renal denervation with radiofrequency was performed supported by high-resolution 3D angiography, which helped confirm the position of the applications in a spiroid fashion.

[Noninvasive coronary angiography using multidetector computed tomography in patients with suspected coronary artery disease and a non-diagnostic exercise treadmill test result].

Background And Objective: We aimed to establish the diagnostic and prognostic usefulness of noninvasive coronary angiography using multidetector computer tomography (MDCT) in patients with clinical suspicion of coronary artery disease (CAD) and a non-diagnostic exercise treadmill test result.

Patients And Method: Retrospective analysis in 33 patients evaluating the incidence of revascularization and hospitalization due to myocardial infarction or angina, and death.

Results: There were obstructive lesions in 7 (21%), non-obstructive lesions in 18 (55%), absence of lesions in 6 (18%), and, finally, 2 patients (6%) had an MDCT deemed as non-evaluable.
