Abstract

:The impact of uncommon etiology cardiomyopathies on Left-ventricular assist device (LVAD)-recipient outcomes is not very well known. This study aimed to characterize patients with uncommon cardiomyopathy etiologies and examine the outcomes between uncommon and ischemic/idiopathic dilated cardiomyopathy. This observational study was conducted in 19 centers between 2006 and 2016. Baseline characteristics and outcomes of patients with uncommon etiology were compared to patients with idiopathic dilated/ischemic cardiomyopathies. Among 652 LVAD-recipients included, a total of 590 (90.5%) patients were classified as ischemic/idiopathic and 62 (9.5%) patients were classified in the "uncommon etiologies" group. Main uncommon etiologies were: hypertrophic (n = 12(19%)); cancer therapeutics-related cardiac dysfunction (CTRCD) (n = 12(19%)); myocarditis (n = 11(18%)); valvulopathy (n = 9(15%)) and others (n = 18(29%)). Patients with uncommon etiologies were significantly younger with more female and presented less co-morbidities. Additionally, patients with uncommon cardiomyopathies were less implanted as destination therapy compared with ischemic/idiopathic group (29% vs 38.8%). During a follow-up period of 9.1 months, both groups experienced similar survival. However, subgroup of hypertrophic/valvular cardiomyopathies and CTRCD had significantly higher mortality compared to the ischemic/idiopathic or myocarditis/others cardiomyopathies. Conversely, patients with myocarditis/others etiologies experienced a better survival. Indeed, the 12-months survival in the myocarditis/others; ischemic/idiopathic and hypertrophic/CTRCD/valvulopathy group were 77%; 65%, and 46% respectively. In conclusion, LVAD-recipients with hypertrophic cardiomyopathy, valvular heart disease and CTRCD experienced the higher mortality rate.

摘要

: 罕见病因心肌病对左心室辅助装置 (LVAD) 受体结局的影响尚不十分清楚。本研究旨在描述不常见心肌病病因患者的特征,并检查不常见和缺血性/特发性扩张型心肌病之间的结局。这项观察性研究在2006年至2016年间在19个中心进行。将不常见病因患者的基线特征和结局与特发性扩张型/缺血性心肌病患者进行比较。在纳入的652例LVAD接受者中,共有590例 (90.5%) 患者被分类为缺血性/特发性,62例 (9.5%) 患者被分类为 “不常见病因” 组。主要少见病因依次为: 肥厚型 (n  =   12(19%) 号决议); 肿瘤治疗相关性心脏功能障碍 (CTRCD) (n  =   12(19%) 号决议); 心肌炎 (n  =   11例 (18%)); 心瓣膜病 (n  =   9(15%) 号决议) 和其他 (n = 18(29%))。不常见病因的患者年龄明显较小,女性较多,合并疾病较少。此外,与缺血/特发性组相比,患有罕见心肌病的患者作为目标治疗的植入较少 (29% vs 38.8%)。在9.1个月的随访期间,两组经历了相似的生存。然而,与缺血性/特发性或心肌炎/其他心肌病相比,肥厚性/瓣膜性心肌病和CTRCD的亚组具有显著更高的死亡率。相反,患有心肌炎/其他病因的患者经历了更好的生存。事实上,心肌炎/其他; 缺血性/特发性和肥厚性/CTRCD/瓣膜病组的12个月生存率分别为77%; 65% 和46%。总之,患有肥厚型心肌病、瓣膜性心脏病和CTRCD的LVAD受者经历了较高的死亡率。

METHODS::Relapsing polychondritis is a rare multi-system disease characterized by inflammation in cartilaginous structures and other connective tissues. Cardiovascular complications occur in 10-51% of the patients. We report a case of concomitant aortic valve replacement, mitral valve replacement, and coronary artery bypass grafting in a patient with relapsing polychondritis. A 71-year-old female with relapsing polychondritis on prednisolone (5 mg/day) for 15 years presented at our hospital for further evaluation of valvular disease. Severe aortic stenosis and severe mitral regurgitation were diagnosed. We performed aortic and mitral valve replacement. During surgery, we found connective tissue surrounding the intima of the sinus of Valsalva and stenosis of the right coronary artery ostium, which was not noted on preoperative coronary angiography. We removed the tissue and performed bypass grafting to the right coronary artery. Postoperative recovery was uneventful, and she was discharged 27 days after surgery.

METHODS:BACKGROUND:The effect of significant mitral regurgitation (MR) on outcomes after continuous flow left ventricular assist device (cfLVAD) implantation remains unclear. METHODS:We performed a retrospective review of prospectively collected data from 159 patients with preoperative severe MR who underwent cfLVAD implantation (2003-2017). Two-step cluster analysis using the log-likelihood distance for post-cfLVAD implantation parameters, which included right ventricular (RV) dysfunction, MR severity, and tricuspid regurgitation (TR) severity. Post-cfLVAD implantation echocardiographic parameters were obtained within the first month. RESULTS:Cluster analysis resulted in 3 groups. Group 1 (n = 67) had mild or less MR with moderate-severe RV dysfunction (RVD). Group 2 (n = 43) had moderate-severe MR with moderate-severe RVD. Group 3 (n = 49) had moderate MR with mild RVD. Group 2 had the largest proportion with Interagency Registry for Mechanically Assisted Circulatory Support score of 1 (30.2%) and 2 (41.9%). They were more likely to undergo temporary mechanical circulatory support (18.6%) and tricuspid valve procedure (62.8%). Group 2 had the highest rate of stroke (30.2%; P = .02), hemolysis (39.5%; P = .01), device thrombosis (30%; P = .01), and worst survival (46.5%; P = .01). Survival at 5 years for groups 1, 2, and 3 were 56.0%, 17.6%, and 55.8%. Regression analysis of the entire population showed that greater MR severity after cfLVAD was associated with RV failure (P < .05; odds ratio, 1.6) and RV assist device use (P = .09; odds ratio, 1.6). After excluding tricuspid valve repairs, MR severity had a positive correlation with TR severity (R = 0.33; P < .01). CONCLUSIONS:After cfLVAD implantation, moderate-severe MR and RVD predicted RV failure. Patients with preoperative moderate-severe MR and TR coupled with moderate-severe RVD might benefit the most from mitral and tricuspid valve intervention.

METHODS:BACKGROUND:Among elderly with severe aortic stenosis (AS), Comprehensive Geriatric Assessment (CGA) originally contributed to address to transcatheter aortic valve implantation (TAVI) patients not suitable to surgical aortic valve replacement(SAVR). Nevertheless, TAVI has recently been proposed also in lower surgical risk patients. AIMS:To evaluate predictors of TAVI procedure and clinical outcomes among these patients. METHODS:For each patient ≥ 65 years with severe AS referring to our Cardiac Surgery Division, CGA was performed, including functional and cognitive status, comorbidity burden, frailty, nutritional status, gait speed, hand-grip strength and number of medications. Surgical risk was evaluated according to the Society of Thoracic Surgeons (STS) score (low-risk < 4%). Post-procedural outcomes (30-day survival and post-procedural complications) were obtained by medical records and a one-year follow-up assessed survival, and functional and cognitive performance. RESULTS:Among 154 subjects (mean age 82.9 years), 52 were at low-risk according to STS score. 32 patients were addressed to TAVI, 20 to SAVR. Variables significantly associated with TAVI-approach were lower gait speed (p 0.030) and higher number of medications (p 0.015). Short and long-term outcomes did not differ between groups. DISCUSSION:Among CGA variables, gait speed and number of medications were associated with the decision to perform TAVI instead of SAVR, even in patients at low surgical risk. 30-day and one-year survival and one-year functional and cognitive decline were similar between groups, despite a relevant prevalence of frailty in the TAVI group. CONCLUSIONS:We suggest that gait speed and number of medications should be considered in selecting appropriate candidates to TAVI among low surgical risk patients.

心脏瓣膜病方向

人的心脏有四个瓣膜,分别为二尖瓣、三尖瓣、主动脉瓣和肺动脉瓣。心脏瓣膜病就是指二尖瓣、三尖瓣、主动脉瓣和肺动脉瓣的瓣膜因风湿热、黏液变性、退行性改变、先天性畸形、缺血性坏死、感染或创伤等出现了病变,影响血流的正常流动,从而造成心脏功能异常,最终导致心力衰竭的单瓣膜或多瓣膜病变。随着人口老龄化加重,老年性瓣膜病以及冠心病、心肌梗死后引起的瓣膜病变也越来越常见。
