01/01/2023 - "Purpose: Intradiscal biacuplasty (IDB) has been proven to be effective for treating lumbar degenerative disc disease (DDD). "
01/19/2015 - "Physical exercise, which is clinically recommended by international guidelines, has proven to be effective for degenerative disc disease (DDD) patients. "
01/01/2017 - "Transaxial fixation is a safe, minimally invasive technique that can offer good results in patients with single-level degenerative disc disease (DDD) at the lumbosacral level, with minimal operative risk."
11/01/2013 - "While TDR has been shown to be a safe and effective alternative to ACDF for treatment of patients with degenerative disc disease (DDD) at a single level of the cervical spine, few studies have focused on the safety and efficacy of TDR for treatment of 2 levels of the cervical spine. "
03/01/2020 - "The patient-reported outcome measure (PROM)-based evaluation in lumbar degenerative disc disease (DDD) is today's gold standard but has limitations. "

09/01/2000 - "It has been reported that older patients with hypertrophic obstructive cardiomyopathy (HOCM) benefited the most from dual chamber (DDD) pacing. "
06/01/2000 - "All patients with hypertrophic obstructive cardiomyopathy included in this multicenter study were either refractory or intolerant to drugs and typically had pressure gradients higher than 30 mm Hg. In 83 patients, mean age 53 (18 to 82) years who responded favorably to a temporary pacing test, a DDD pacemaker was implanted. "
02/01/2008 - "In patients with hypertrophic obstructive cardiomyopathy (HOCM), DDD pacing appears to be effective to reduce the pressure gradient between the left ventricle and the aorta. "
06/15/2006 - "In conclusion, DDD pacing is effective in reducing the LVOT gradient and improving functional capacity in adult patients with hypertrophic cardiomyopathy. "
01/01/1996 - "DDD pacing has been advocated as an effective treatment for drug refractory obstructive hypertrophic cardiomyopathy. "

01/01/2020 - "This pre-specified analysis evaluated whether the clinically significant reduction in syncope burden demonstrated by dual-chamber pacing with closed loop stimulation (DDD-CLS) reported in the SPAIN trial translates into improved QoL. "
04/01/1989 - "Thirty-nine consecutive patients with recurrent syncope and either cardioinhibitory or mixed type carotid sinus syndrome were studied to determine the efficacy of ventricular (VVI) pacing in 16, and dual chamber (DDD/DVI) in 23 patients. "
04/01/2003 - "The aim of the study was to evaluate both long term clinical outcome, including the first recurrence of syncope, with DDDR-CLS pacing and acute precipitation of vasovagal fainting with DDDR-CLS mode compared with DDD during head up tilt testing. "
07/01/2018 - "No further episodes of syncope recurred after the implantation of a DDD pacemaker. "
01/01/2018 - "In patients with cardioinhibitory VVS, CLS reduces the occurrence of syncope induced by HUTT, compared with DDD pacing. "

01/01/2013 - "Immediately after the device was upgraded to the DDD-biventricular pacemaker, the patient's heart failure symptoms and cardiac function dramatically improved, which suggests that AV dissociation has a much more negative impact on the cardiac function than AF in patients with CHF."
07/02/2017 - "Heart failure occurred in 2 patients at 6 and 8 years after implantation whose heart functions improved after switching from VVI to DDD or adding ACEI . "
01/01/2015 - "Twelve CRT patients with non-ischemic heart failure (NYHA class II-III) were enrolled in a randomized, double-blind, crossover trial, in which the basal pacing rate was set at DDD-60 and DDD-80 for 3 months (DDD-R for 2 patients). "
05/07/2013 - "This study sought to test whether measures of pulsatile arterial function are useful for diagnosing heart failure with preserved ejection fraction (HFPEF), in comparison with and in addition to tissue Doppler echocardiography (TDE). "
12/01/2012 - "In the study, the presence and extent of cardiac dyssynchrony were investigated in patients with heart failure both with narrow and wide QRS complexes using tissue Doppler echocardiography (TDE). "

12/01/2002 - "Although atrial pacing is a more physiological mode of stimulation in sinus node dysfunction, the pacing modes most often are used DDD and VVI. The aim of our study was to demonstrate that AAI/AAIR pacing is effective and safe by analyzing the complications and mortality of this pacing mode in a long-term follow-up study. "
10/01/1988 - "Palpitation and general wellbeing were significantly improved during DDD pacing in the eight patients with sick sinus syndrome. "
01/01/2015 - "According to the current guidelines, atrioventricular (DDD) pacing is superior to atrial pacing (AAI) in the treatment of sick sinus syndrome (SSS). "
12/01/2003 - "Another trial the Pacemaker Selection in the Elderly (PASE) did suggest that for sinus node disease, DDD-R pacing may lead to an improvement in quality of life mainly early post implant. "
09/03/2021 - "A subject of the study is a 74-year-old woman with a sick sinus syndrome (SSS) and a previously implanted physiological DDD/R pacemaker. "
