Long-term outcomes of rigid ring versus De Vega annuloplasty for functional tricuspid regurgitation: A propensity score-matching analysis

ObjectiveThis study was conducted to compare the outcomes of rigid ring versus De Vega annuloplasty for the treatment of functional tricuspid regurgitation (TR).MethodsFrom 2003 to 2017, De Vega annuloplasty (group D) was used in 231 patients, and rigid ring annuloplasty (group R) was used in 204 patients for the treatment of functional TR during left-sided valve surgery. A propensity score-matching analysis was used to pair group D (n = 109) with group R (n = 109). The primary outcomes were long-term overall survival and cardiac death, and the secondary outcomes were tricuspid valve-related events and TR recurrence (TR moderate or severe). The follow-up data were complete in 99.6% (447 out of 449) of the patients with a follow-up duration of 102 months.ResultsThere were no differences in the overall survival and cardiac death between the propensity score-matched groups (P = .793 and P = .175, respectively) up to 14 years after surgery. Tricuspid valve-related events, including cardiac death, permanent pacemaker implantation, thromboembolism, bleeding and tricuspid valve reoperation were also similar between the 2 matched groups during the follow-up (P > .999). However, cumulative incidence of TR recurrence was significantly higher in group R than in group D (P = .007). Multivariate analysis indicated the annuloplasty method (De Vega) and preoperative TR grade as risk factors for late TR recurrence.ConclusionsIn functional TR, annuloplasty methods did not influence long-term overall survival, cardiac mortality, and tricuspid valve-related events. However, rigid ring annuloplasty showed less late TR recurrence. Rigid ring annuloplasty can be considered for the treatment of functional TR in terms of its better durability.     

Thalamic deep brain stimulation for Tourette Syndrome: A naturalistic trial with brief randomized,double-blinded sham-controlled periods

BackgroundThere is still a lack of controlled studies to prove efficacy of thalamic deep brain stimulation for Tourette's Syndrome.ObjectivesIn this controlled trial, we investigated the course of tic severity, comorbidities and quality of life during thalamic stimulation and whether changes in tic severity can be assigned to ongoing compared to sham stimulation.MethodsWe included eight adult patients with medically refractory Tourette's syndrome. Bilateral electrodes were implanted in the centromedian-parafascicular-complex and the nucleus ventro-oralis internus. Tic severity, quality of life and comorbidities were assessed before surgery as well as six and twelve months after. Short randomized, double-blinded sham-controlled crossover sequences with either active or sham stimulation were implemented at both six- and twelve-months’ assessments. The primary outcome measurement was the difference in the Yale Global Tic Severity Scale tic score between active and sham stimulation. Adverse events were systematically surveyed for all patients to evaluate safety.ResultsActive stimulation resulted in significantly higher tic reductions than sham stimulation (F = 79.5; p = 0.001). Overall quality of life and comorbidities improved significantly in the open-label-phase. Over the course of the trial two severe adverse events occurred that were resolved without sequelae.ConclusionOur results provide evidence that thalamic stimulation is effective in improving tic severity and overall quality of life. Crucially, the reduction of tic severity was primarily driven by active stimulation. Further research may focus on improving stimulation protocols and refining patient selection to improve efficacy and safety of deep brain stimulation for Tourette's Syndrome.     

Italian Chapter of the International Society of Cardiovascular Ultrasound expert consensus document on coronary computed tomography angiography: overview and new insights

Coronary computed tomography angiography is a noninvasive heart imaging test currently undergoing rapid development and advancement. The high resolution of the three‐dimensional pictures of the moving heart and great vessels is performed during a coronary computed tomography to identify coronary artery disease and classify patient risk for atherosclerotic cardiovascular disease. The technique provides useful information about the coronary tree and atherosclerotic plaques beyond simple luminal narrowing and plaque type defined by calcium content. This application will improve image‐guided prevention, medical therapy, and coronary interventions. The ability to interpret coronary computed tomography images is of utmost importance as we develop personalized medical care to enable therapeutic interventions stratified on the bases of plaque characteristics. This overview provides available data and expert's recommendations in the utilization of coronary computed tomography findings. We focus on the use of coronary computed tomography to detect coronary artery disease and stratify patients at risk, illustrating the implications of this test on patient management. We describe its diagnostic power in identifying patients at higher risk to develop acute coronary syndrome and its prognostic significance. Finally, we highlight the features of the vulnerable plaques imaged by coronary computed tomography angiography.     

补虚逐瘀法联合针灸对冠心病便秘患者心脏不良事件的影响

目的:观察补虚逐瘀法联合针灸对冠心病便秘患者心脏不良事件的影响。方法:选取2014年9月至2016年10月辽宁中医药大学附属第三医院收治的冠心病便秘患者100例,进行回顾性研究,按治疗方式的不同分成联合组(n=56)和单针组(n=44),2组均给予冠心病常规治疗药物,单针组仅给予穴位针灸,联合组在单针组的基础加服补虚逐瘀汤,记录和比较2组的患者便秘情况的临床疗效、心电图疗效及心脏不良事件次数。结果:治疗后,联合组在心脏不良事件发生率(1.79%)的比较明显少于单针组(15.90%)(P0.05),联合组的心电图疗效(92.86%)优于单针组(68.18%)(P0.05)但2组在便秘情况临床疗效的差异无统计学意义(P0.05).结论:实施补虚逐瘀法联合针灸对冠心病便秘患者的治疗上,可明显改善患者心功能,有效减少患者排便时心脏不良事件的发生率,值得临床推广。     

What about doctors? The impact of medical errors

Medical error is a distressing event to the patient and the health care providers. The impact of such events has been well studied on patients but poorly on health professionals. These events are still considered as a taboo in the medical culture and hence missed as great learning opportunities. They have negative impact on doctors' emotional wellbeing, general quality of life, and their professional practice and conduct. Medical errors and adverse events also affect the quality and cost of the health service. Health service administrations should provide healthcare professionals involved in such events with professional support and counselling services, and should consider and treat them as second victims.
