What's the difference between rhotacism and rotacism?
Rhotacism
Definition:
(n.) An oversounding, or a misuse, of the letter r; specifically (Phylol.), the tendency, exhibited in the Indo-European languages, to change s to r, as wese to were.
Example Sentences:
(1) The three perceptual dimensions corresponded to tongue advancement, vowel height, and rhotacization.
Rotacism
Definition:
(n.) See Rhotacism.
Example Sentences:
(1) When a guide wire crossed the lesion aided only by the support of the ROTACS without the use of rotation this was counted as a success that was not device specific.
(2) Low-speed rotational angioplasty (ROTACS, Osypka, Medtronic) was employed in 152 patients with chronic coronary occlusions in whom conventional guide wire techniques failed.
(3) The ROTACS crossed only two of the 10 chronic lesions (20% device specific success rate); however, the support it provided enabled a guide wire to cross a further two lesions and allowed subsequent successful angioplasty in four of the 10 patients.
(4) The authors report their preliminary results with the Rotacs system in the reopening of chronic coronary artery occlusion by low-speed rotational angioplasty.
(5) It is concluded that the use of low speed rotational angioplasty (ROTACS) can improve the results of nonoperative invasive treatment, both in peripheral and in coronary arteries.
(6) Preliminary assessment of the efficacy and safety of the low speed rotational angioplasty catheter system (ROTACS).
(7) The ROTACS may extend the range of patients with coronary artery occlusion or critical stenosis who can be treated non-surgically.
(8) It is concluded that the use of low-speed rotational angioplasty (ROTACS) can improve the results of nonoperative invasive treatment, both in peripheral and in coronary arteries.
(9) The low-speed rotational transluminal angioplasty catheter system (ROTACS) is a recently available device for recanalization of occlusions prior to balloon angioplasty.
(10) Three of the six patients in whom the ROTACS was unsuccessful had coronary artery dissection without sequelae.
(11) In the one patient with acute coronary occlusion the ROTACS was advanced over the guide wire to allow passage of an angioplasty balloon where this had previously proved impossible.
(12) A slowly rotating catheter (Rotacs) facilitates primary recanalisation of long occlusions prior to balloon dilatation.
(13) The following NON-POBA-PTCA-techniques ("New devices") were used in Austria for the first time: Atherectomy, stent, lasers, TEC, ROTABLATOR, ROTACS, magnum wire and angioscopy accounted for 11.3% of all PTCA cases in Austria recently.
(14) While attempting to recanalize a right coronary artery obstruction by using a low-speed rotating catheter (Rotacs), proximal rupture of the catheter body occurred with entrapment of the blunt tip in the obstruction.
(15) The complication rate of Rotacs technique compares with that of the conventional methods.
(16) 75 patients with difficult occlusions in the superficial and popliteal arteries were treated by the "Rotacs" system.
(17) 60 patients in whom the occlusions could not be passed with a conventional wire were treated with the ROTACS system.
(18) Rates of success and of complication necessitating reintervention were, for balloon angioplasty (57 cases) 81% and 19%, for directional atherectomy (16 cases) 75% and 0%, for the Rotablator (12 cases) 42% and 42%, for stent implantation (10 cases) 100% and 0%, for excimer laser angioplasty (6 cases) 17% and 33%, and for Rotacs recanalisation (3 cases) 67% and 0%, respectively.
(19) The presence of large collaterals originating just proximal to the occlusion with an acute angle, and insufficient space between the puncture site and the occlusion for placing an introducer sheath are reported to be limitations for ROTACS.
(20) To retrieve the device, it was necessary to severe the guiding catheter and the flexible tube of the Rotacs.
