Background To date, preclinical studies evaluating MRI-guided ablation have used non-irrigated catheters limited to test lesions in the right heart. Modern complex EP procedures require externally irrigated catheters to produce adequate lesion depth. We present the first feasibility study of an externally-irrigated MRI-compatible ablation catheter, and integrated EP pacing and recording system....

BACKGROUND Radiofrequency (RF) ablation of cavotricuspid isthmus (CTI) dependent flutter can be performed using different types of ablation catheters. It has been proposed that irrigated and large-tip catheters are capable of creating larger lesions, resulting in greater efficacy. This prospective, randomised clinical study compared the efficacy of irrigated and large-tip catheters of different...

The Middle East encompasses five ecological domains: (1) the humid highlands and their intermontane valleys, where rainfed farming was begun and permanent settlements were first established; (2) the semi-arid steppes, where the lesser amount and instability of rainfall made rainfed farming marginal but still provided vegetative resources that could be utilized by semi-nomadic pastoralists; (3) ...

In the present study, we investigated impact of treated wastewater (TWW) irrigation on prevalence antibiotic resistance genes (ARGs) in subsoil pore-water, a so-far under-appreciated matrix. We hypothesized that TWW increases ARG pore-water. This hypothesis was tested using multiphase approach, which consisted sampling percolated pore-water from lysimeter-wells real-scale TWW-irrigated field, o...

Influences of irrigation frequency on the growth and flowering of chrysanthemum grown under restricted root volume were tested. Chrysanthemum cuttings (Chrysanthemum morifolium "Reagan White") were grown in seedling tray which contained coconut peat in volumes of 73 and 140 cm(3). Plants were irrigated with drip irrigation at irrigation frequencies of 4 (266 mL), 6 (400 mL), and 8 (533 mL) time...
