Hemodynamic effect of supra-annular implantation of SAPIEN 3 balloon expandable valve.

The hemodynamic impact of the implantation depth for balloon-expandable valves is under-investigated, especially with higher implantation techniques. We assessed the hemodynamic performance of supra-annular SAPIEN 3 valve implantation. This retrospective study involved consecutive patients who underwent transcatheter aortic valve replacement (TAVR) using the SAPIEN 3. The device implantation depth and transcatheter heart valve (THV) leaflet-nadir position were angiographically analyzed, and supra-annular implantation was defined as a higher leaflet-nadir position than the original annular line. The Doppler hemodynamic status was evaluated at patient discharge. Among 184 patients, 120 (65%) underwent supra-annular implantation, and their mean implantation depth was significantly lower than that of intra-annular implantation (1.1 vs. 5.2 mm, p < 0.001). No patients developed valve embolization or coronary occlusion, and none required the TAV-in-TAV procedure. Two (1.6%) patients in the supra-annular implantation group had a mild or greater paravalvular leak. Echocardiography demonstrated that supra-annular implantation had better hemodynamic performance, showing a larger indexed effective orifice area (iEOA) compared with intra-annular implantation (1.09 vs. 0.97 cm2/m2, p < 0.01). There was a weak but negative correlation between the implantation depth and iEOA (r = - 0.27, p < 0.01). Moderate or severe prosthesis-patient mismatch (PPM) was found in 35.9% of the intra-annular group and 9.2% of supra-annular of the supra-annular group (p < 0.01). In the multivariable analysis, supra-annular implantation was an independent predictor of better THV function (iEOA > 0.85). Supra-annular SAPIEN 3 implantation provides beneficial hemodynamic effects and reduces the PPM risk.

Long-term hearing prognosis after vestibular schwannoma surgery with retrolabyrinthine approach.

PURPOSE: The retrolabyrinthine approach is a surgical method designed to preserve hearing after surgery. When paired with intraoperative monitoring and an endoscope, this approach has demonstrated high rates of postoperative hearing preservation. However, the long-term prognosis of hearing preservation after utilizing this approach for vestibular schwannomas remains unexplored. This study aimed to examine the long-term outcomes of preserved hearing, providing insights into the suitability of the retrolabyrinthine approach for hearing preservation surgery. METHODS: This study included 34 patients with preserved hearing after vestibular schwannoma surgery using the retrolabyrinthine approach at a single center. Long-term hearing prognosis and requirement for additional interventions were retrospectively examined. RESULTS: Immediate after post-operative hearing preservation rate was 71.7%. Among the 34 patients with preserved hearing post-vestibular schwannoma surgery, four (11.8%) required additional interventions. Other patients experienced a gradual deterioration in their hearing status, with an approximate 10 dB decline during the 5-year follow-up; however, a serviceable hearing level persisted long after the surgery in these individuals. CONCLUSIONS: This study indicated the rationale for the retrolabyrinthine approach as a hearing preservation surgery for vestibular schwannomas, emphasizing its long-term hearing prognosis.

Clip opening while locked after transcatheter edge-to-edge mitral valve repair with different onset times: a case series.

Background: Transcatheter edge-to-edge mitral valve repair is now available in many countries and has achieved favourable therapeutic outcomes. However, there have been no reported cases of clip opening while locked (COWL) during the acute phase using the MitraClip G4 system (Abbott, Abbott Park, IL, USA). Case summary: We present two cases of COWL occurring at different phases: one immediately after clip release and the other 2 days post-procedure. In both cases, the initial treatment involved the use of the XTW system. Subsequently, an additional XT system was deployed for the deterioration of mitral regurgitation caused by COWL, without any complications. Discussion: The MitraClip G4 system offers four size variations, providing a larger grasping area and increased flexibility for accessing complex lesions. Furthermore, the complication rate decreased with increasing operator experience and device generation. However, it has been reported that COWL can occur after the clip is deployed during TEER. Although the mechanism of COWL is unclear, the nature and mobility of the valve leaflets and the product specificity of the MitraClip may be involved.

Binaural hearing aid intervention for a patient with nonserviceable hearing loss after surgery for vestibular schwannoma: A case report.

A vestibular schwannoma is a benign tumor; however, the schwannoma itself and interventions can cause sensorineural hearing loss. Most vestibular schwannomas are unilateral tumors that affect hearing only on one side. Attention has focused on improving the quality of life for patients with unilateral hearing loss and therapeutic interventions to address this issue have been emphasized. Herein, we encountered a patient who was a candidate for hearing preservation surgery based on preoperative findings and had nonserviceable hearing after the surgery, according to the Gardner-Robertson classification. Postoperatively, the patient had decreased listening comprehension and ability to localize sound sources. He was fitted with bilateral hearing aids, and his ability to localize sound sources improved. Although the patient had postoperative nonserviceable hearing on the affected side and age-related hearing loss on the unaffected side, hearing aids in both ears were useful for his daily life. Therefore, the patient was able to maintain a binaural hearing effect and the ability to localize the sound source improved. This report emphasizes the importance of hearing preservation with vestibular schwannomas, and the demand for hearing loss rehabilitation as a postoperative complication can increase, even if hearing loss is nonserviceable.

Transcatheter aortic valve implantation for structural valve deterioration of homograft surgical aortic valve using SAPIEN3 Ultra RESILIA: a case report.

Background: There are a few case reports regarding transcatheter aortic valve implantation (TAVI) for deteriorated surgical homograft. Case summary: We present a case of severe structural valve deterioration (SVD) of homograft surgical aortic valve presenting severe aortic regurgitation in an 84-year-old man with decompensated heart failure. We performed TAVI in homograft valve using 23 mm SAPIEN3 Ultra RESILIA. The resulting grade of paravalvular regurgitation was trace, the post-operative effective orifice area (EOA) was 1.66 cm2 (index EOA: 1.19 cm2/m2), and device success was achieved. Discussion: Stented bioprosthetic valves are more commonly implanted than mechanical and stentless bioprosthetic valves. In the 1980s and the early 1990s, homografts became particularly popular as alternatives to stented valves. There are several reports of TAVI for homograft SVD, but the paravalvular leakage grade is worse than that of redo-surgical aortic valve replacement, although the mortality rate is lower. However, the valves used in these reports were from older valves such as SAPIEN XT or SAPIEN3. There are no reports using SAPIEN3 Ultra RESILIA with a significant reduction in paravalvular leak due to an external textured polyethylene terephthalate skirt extending 40% higher above the valve inflow than the classical SAPIEN3, which is now available. Transcatheter aortic valve implantation using SAPIEN3 Ultra RESILIA showed good therapeutic efficacy.

Sarcopenia accompanied by systemic inflammation can predict clinical outcomes in patients with head and neck cancer undergoing curative therapy.

Objectives: Evaluation of sarcopenia accompanied by systemic inflammation status is a more beneficial prognostic marker than sarcopenia alone in various cancers. However, few studies have focused on this combination in patients with head and neck squamous cell cancer (HNSCC). In this study, we investigated how the combination of sarcopenia and systemic inflammation could affect survival in patients with HNSCC. Moreover, we explored which systemic inflammation markers could be better prognostic indicators when accompanied by sarcopenia. Materials and methods: We retrospectively reviewed the medical records of patients with HNSCC treated between 2012 and 2016. Sarcopenia was defined by the skeletal muscle area measured on a computed tomography image slice at the level of the third cervical vertebra. The neutrophil/lymphocyte, platelet/lymphocyte, and lymphocyte/monocyte ratios (NLR, PLR, and LMR, respectively) were used as systemic inflammation markers that were combined with sarcopenia to evaluate prognosis. Results: A total of 100 patients were enrolled, and 71 patients were considered sarcopenia. Patients with sarcopenia had significantly lower LMR and higher NLR and PLR. They also showed worse overall survival (OS) and progression-free survival (PFS). The comparative assessment of multiple combination patterns of sarcopenia and systemic inflammation indices proved that sarcopenia plus LMR considered as most reliable indicator for prognosis in HNSCC patients. Sarcopenia plus low LMR was a significantly poor prognostic factor both for OS and PFS with greater HR values than sarcopenia alone. Conclusions: The combination of sarcopenia and LMR was considered the most sensitive prognostic factor in patients with HNSCC, suggesting it might be beneficial for identifying poor outcome risks.

Prognostic Significance of Asymptomatic Cerebral Infarction in Patients After Cardiac Catheterization.

Recent studies have showed that asymptomatic cerebral infarction (ACI) developed in a reasonable number of patients after cardiac catheterization. However, no study has investigated the long-term prognostic impact of ACI after cardiac catheterization. We investigated whether ACI after cardiac catheterization affects long-term mortality and subsequent cardiovascular events.We retrospectively enrolled patients who underwent cardiac catheterization before cardiac surgery and cerebral diffusion-weighted magnetic resonance imaging (DWI). The incidence and clinical features of ACI were investigated. The long-term prognosis, including all-cause mortality and subsequent major cardiovascular events (MACE; all-cause mortality, stroke, acute myocardial infarction, fatal arrhythmia, and hospitalized heart failure), was also assessed.A total of 203 patients were enrolled. Of these, 10.3% had ACI diagnosed by DWI. There were no differences in baseline characteristics between patients with and without ACI, except more frequent history of symptomatic stroke in patients with ACI. In the Kaplan-Meier analysis during a median follow-up of 1009 days, the patients with ACI showed worse mortality and a slightly higher occurrence of MACE compared with those without ACI (P = 0.01 and P = 0.08, respectively). In addition, ACI was a prognostic marker independent of age, surgery type, and history of stroke.ACI after cardiac catheterization frequently developed and was also associated with long-term prognosis. It may be an independent prognostic marker in high-risk patients who underwent subsequent cardiac surgery.

Prediction of Cochlear Implant Effectiveness With Surface-Based Morphometry.

OBJECTIVE: This study aimed to determine whether surface-based morphometry of preoperative whole-brain three-dimensional T1-weighted magnetic resonance imaging (MRI) images can predict the clinical outcomes of cochlear implantation. STUDY DESIGN: This was an observational, multicenter study using preoperative MRI data. SETTING: The study was conducted at tertiary care referral centers. PATIENTS: Sixty-four patients with severe to profound hearing loss (≥70 dB bilaterally), who were scheduled for cochlear implant (CI) surgery, were enrolled. The patients included 19 with congenital hearing loss and 45 with acquired hearing loss. INTERVENTIONS: Participants underwent CI surgery. Before surgery, high-resolution three-dimensional T1-weighted brain MRI was performed, and the images were analyzed using FreeSurfer. MAIN OUTCOME MEASURES: The primary outcome was monosyllable audibility under quiet conditions 6 months after surgery. Cortical thickness residuals within 34 regions of interest (ROIs) as per the Desikan-Killiany cortical atlas were calculated based on age and healthy-hearing control regression lines. RESULTS: Rank logistic regression analysis detected significant associations between CI effectiveness and five right hemisphere ROIs and five left hemisphere ROIs. Predictive modeling using the cortical thickness of the right entorhinal cortex and left medial orbitofrontal cortex revealed a significant correlation with speech discrimination ability. This correlation was higher in patients with acquired hearing loss than in those with congenital hearing loss. CONCLUSIONS: Preoperative surface-based morphometry could potentially predict CI outcomes and assist in patient selection and clinical decision making. However, further research with larger, more diverse samples is necessary to confirm these findings and determine their generalizability.

Prognostic impact of early aortic volume changes at hospital discharge in patients with acute type B aortic dissection.

BACKGROUND: Early prediction of aorta-related events is important for determining subsequent treatment strategies in patients with acute aortic dissection. However, most studies evaluated long-term aortic growth rates by annual assessment. The purpose of our study was to determine whether the in-hospital growth rate of aortic volume was associated with aorta-related events. METHODS: We studied 116 patients with uncomplicated type B acute aortic dissection. We analyzed whether changes in aortic volume were associated with aorta-related events during a 5-year follow-up. According to the growth rate from admission to discharge, patients were divided into two groups: Increase >0 (aortic volume: n = 59, aortic diameter: n = 43) and Reduction ≤0 (aortic volume: n = 57, aortic diameter: n = 73) in maximum aortic diameter or aortic volume. The primary endpoint was the discriminative ability of the growth rate of aortic volume for aorta-related events. RESULTS: According to the evaluation of aortic volume changes, the Increase group had significantly higher aorta-related event rates than those in the Reduction group (49.2 % vs. 3.5 %, respectively; p < 0.001). Receiver operating characteristics analysis showed that the growth rate of aortic volume had a clearly useful discrimination, with an area under the curve of 0.84, whereas the discriminative ability of the growth rate of maximum aortic diameter was poor (area under the curve: 0.53). Multivariate analysis showed that the growth rate of aortic volume from admission to discharge was an independent predictor of aorta-related events (hazard ratio, 26.3; 95 % confidence interval, 2.04-286.49; p = 0.001). CONCLUSIONS: In-hospital evaluation of aortic volume was helpful to predict long-term aorta-related events in patients with uncomplicated type B acute aortic dissection.

A novel intraoperative continuous monitoring method combining dorsal cochlear nucleus action potentials monitoring with auditory nerve test system.

Highly accurate real-time cochlear nerve monitoring to preserve cochlear nerve function is essential for simultaneous cochlear implantation and ipsilateral vestibular schwannoma resection. In the present study, we developed a novel real-time monitoring system that combines dorsal cochlear nucleus action potential monitoring with intracochlear stimulating electrodes (Auditory Nerve Test System, ANTS). We used this system for a case with vestibular schwannoma resection via the translabyrinthine approach. The monitoring system developed in this study detected highly reliable evoked potentials from the cochlear nerve every two seconds continuously during tumor resection. Near-total tumor resection was achieved, and cochlear implantation was performed successfully after confirming the preservation of cochlear nerve function in a case. The patient's hearing was well compensated by cochlear implantation after surgery. Our novel method continuously achieved real-time monitoring of the cochlear nerve every two seconds during vestibular schwannoma resection. The usefulness of this monitoring system for simultaneous tumor resection and cochlear implantation was demonstrated in the present case. The system developed in this study is compatible with continuous facial nerve monitoring. This highly accurate and novel monitoring method will broaden the number of candidates for this type of surgery in the future.

Haemodynamic effects of inhaled nitric oxide in acute myocardial infarction complicated by right heart failure under ECPELLA support: case report.

Background: Recently, mechanical support obtained with the combination of venoarterial extracorporeal membrane oxygenation (VA-ECMO) and an Impella device, together referred to as ECPELLA, has been shown to be effective for acute myocardial infarction with cardiogenic shock. However, methods for withdrawing VA-ECMO in acute myocardial infarction cases complicated by right ventricular dysfunction are yet to be established. Here, we report the effective use of inhaled nitric oxide during the weaning of VA-ECMO from the ECPELLA management of a patient with acute myocardial infarction with cardiogenic shock. Case summary: An 81-year-old man with an acute extensive anterior wall myocardial infarction with cardiogenic shock was supported with ECPELLA to improve his haemodynamics. During ECPELLA, the Impella device could not maintain sufficient flow. Echocardiography revealed a small left ventricle and an enlarged right ventricle, indicating acute right heart failure. Inhaled nitric oxide was initiated to reduce right ventricle afterload, which decreased pulmonary artery pressure from 34/20 to 27/13 mmHg, improved right and left ventricle sizes, and stabilized the Impella support. Afterward, VA-ECMO could be withdrawn because the Impella alone was sufficient for haemodynamic support. Discussion: Inhaled nitric oxide improved right ventricle performance in a patient with severe myocardial infarction with right heart failure supported by ECPELLA. Thus, we suggest that inhaled nitric oxide facilitates the weaning of VA-ECMO from patients with refractory right ventricular dysfunction who are supported by ECPELLA.

Impact of quantitative flow ratio on graft function in patients undergoing coronary artery bypass grafting.

Recent studies showed that preoperative functional assessment with fractional flow reserve (FFR) could predict a long-term patency of arterial bypass grafts in patients with coronary artery bypass grafting (CABG). Quantitative flow ratio (QFR) is a novel angiography-based approach to estimate FFR. This study aimed to investigate whether preoperative QFR could discriminate arterial bypass function at 1 year after surgery. The PRIDE-METAL registry was a prospective, multicenter observational study that enrolled 54 patients with multivessel coronary artery disease. By protocol, left coronary stenoses were revascularized by CABG with arterial grafts, whereas right coronary stenoses were treated with coronary stenting. Follow-up angiography at 1 year after surgery was scheduled to assess arterial graft patency. QFR was performed using index angiography by certified analysts, blinded to bypass graft function. The primary end point of this sub-study was the discriminative ability of QFR for arterial graft function, as assessed by receiver-operating characteristic curve. Among 54 patients enrolled in the PRIDE-METAL registry, index and follow-up angiography was available in 41 patients with 97 anastomoses. QFR were analyzed in 35 patients (71 anastomoses) with an analyzability of 85.5% (71/83). Five bypass grafts were found to be non-functional at 1 year. The diagnostic performance of QFR was substantial (area under the curve: 0.89; 95% confidence interval: 0.83 to 0.96) with an optimal cutoff of 0.76 to predict functionality of bypass grafts. Preoperative QFR is highly discriminative for predicting postoperative arterial graft function.Trial registration: Clinical.gov reference: NCT02894255.

Up-Titration of Sacubitril/Valsartan Among Patients With Heart Failure and Preserved Ejection Fraction.

AIMS: In recent large trials, sacubitril/valsartan demonstrated favorable effects in patients with HF. However, many patients do not achieve the target dose of treatment. This study investigated the factors linked to up-titration of sacubitril/valsartan in patients with heart failure and preserved ejection fraction (HFpEF). METHODS: Using a multicenter retrospective database, 204 consecutive patients with HFpEF (left ventricular ejection fraction ≥ 40%) who were treated with sacubitril/valsartan between October 2020 and March 2022 were analyzed. Up-titration was defined as an increase in dosage above 24/26 mg BID beyond 12 weeks after the initiation of sacubitril/valsartan. RESULTS: Among the patients, 55% underwent up-titration, and 8% discontinued the drug. The baseline systolic blood pressure (SBP) was higher in patients with up-titration than in those with no up-titration; SBP values similar to that at baseline were observed between the 2 groups at 2 to 4 weeks and at 12 weeks after the commencement of sacubitril/valsartan treatment. The majority of those who discontinued sacubitril/valsartan did so because of hypotension. The multivariable logistic regression model showed that a history of hypertension, history of atrial fibrillation, baseline SBP, and baseline estimated glomerular filtration rate <60 mL/min/1.73 m2 were associated with sacubitril/valsartan up-titration. CONCLUSION: Approximately half of all patients did not undergo up-titration, and 8% of those with HFpEF discontinued the sacubitril/valsartan therapy. For aggressive up-titration and continuation of sacubitril/valsartan, patients with lower baseline SBP, renal dysfunction, absence of a history of hypertension, and presence of atrial fibrillation may require more careful monitoring.

Risk factors related to psychological distress among elderly patients with cardiovascular disease.

AIMS: Psychological distress is associated with poor prognosis in patients with cardiovascular disease (CVD). However, factors related to psychological distress in elderly patients with CVD are less understood. We aim to investigate the rate of psychological distress in elderly patients with CVD in comparison with that of patients without CVD and to examine the clinical, socio-economic, and lifestyle factors associated with this condition. METHODS AND RESULTS: Data from a nationwide population-based study in Japan of patients aged ≥60 years were extracted, and 1:1 propensity score matching was conducted of patients with and without CVD. Psychological distress was assessed using the K6 scale, on which a score ≥6 was defined as psychological distress. Of the 24 388 matched patients, the rate of psychological distress was significantly higher among patients with CVD compared with those without CVD (29.8 vs. 20.5%, P < 0.0001). The multivariate analysis revealed that female sex, comorbidities, except for hypertension, current smoking status, daily sleep duration of <6 vs. ≥8 h, home renter vs. owner, retired status, having a walking disability, and lower monthly household expenditure were independently associated with psychological distress. Walking disability was observed to be in greatest association with psychological distress (odds ratio 2.69, 95% confidence interval 2.46-2.93). CONCLUSION: Elderly patients with CVD were more likely to have psychological distress compared with those without CVD. Multiple factors, including clinical, socio-economic, and lifestyle variables, were associated with psychological distress. These analyses may help healthcare providers to identify high-risk patients with psychological distress in a population of older adults with CVD.

Association between atherosclerosis, hearing recovery, and hearing in the healthy ear in idiopathic sudden sensorineural hearing loss: a retrospective chart analysis.

Atherosclerosis is reported to be a risk factor for the severity of idiopathic sudden sensorineural hearing loss (ISSNHL). We evaluated the hypothesis that atherosclerosis affects the hearing thresholds of both the affected and healthy sides of ISSNHL patients. We conducted multivariate analyses on retrospectively collected data of patients with ISSNHL (N = 762) to evaluate the relationship between known factors linked to atherosclerosis and hearing thresholds on affected and healthy sides and whether these factors are prognostic for hearing recovery. Older ages, vertigo or dizziness, diabetes mellitus, and congestive heart failure were significantly related to higher hearing thresholds on the affected side. Older ages, male, and vascular disease were significantly related to higher hearing thresholds on the healthy side. Vertigo or dizziness, severe hearing loss and hearing loss at high frequencies on the affected side, higher hearing thresholds on the healthy side, regular anticoagulant medication, and delayed steroid treatment were significantly related to lack of recovery. Since several atherosclerosis-related factors are associated with higher hearing thresholds on both affected and healthy sides in ISSNHL and higher hearing thresholds on the healthy side predict poorer prognosis, diagnosis, and predicting prognosis of ISSNHL may benefit from rigorous evaluation of patients' cardiovascular comorbidities and hearing levels on both the healthy and affected sides.

Effects of hearing aids in patients with unilateral tinnitus with acquired ipsilateral sensorineural hearing loss.

OBJECTIVES: To evaluate the effectiveness of sound therapy using hearing aids in patients experiencing tinnitus with acquired unilateral sensorineural hearing loss. METHODS: A total of 97 patients with unilateral tinnitus with acquired ipsilateral sensorineural hearing loss were included. Evaluation involved self-report questionnaires administered at entry, 3 months after treatment, and 1 year after treatment. RESULTS: The mean Tinnitus Handicap Inventory score before treatment decreased significantly (p < 0.01) at 3 months (50.0 ± 24.5-12.7 ± 16.2), and 1 year (53.3 ± 25.5-8.79 ± 13.9), after treatment. Moreover, the visual analog scale score decreased significantly at 3 months (loudness, 69.6 ± 21.9-29.1 ± 27.2; annoyance, 71.1 ± 24.7-22.7 ± 25.5) and 1 year (loudness, 69.8 ± 22.0-21.1 ± 26.1; annoyance, 72.7 ± 25.6-19.4 ± 27.6). Approximately 80-90% of patients noticed improvements in tinnitus annoyance and loudness, as determined by their responses to the questionnaires of subjective symptom improvement. CONCLUSIONS: Hearing aids are remarkably effective for patients with unilateral tinnitus with acquired ipsilateral sensorineural hearing loss.

Cancer screening: Possibility of underscreening in older adult population with a history of cardiovascular disease.

BACKGROUND: Cardiovascular disease and cancer share a number of risk factors and pathophysiologic mechanisms. Although risk management and early detection of cancer in patients with cardiovascular disease are important, preventive efforts in cardiology and oncology have been relatively disconnected. This study aimed to investigate the rate of cancer screening in a population of older adults with cardiovascular disease. METHODS: This study used data from the 2019 Comprehensive Survey of Living Conditions. Data on participants aged 60 years or older were extracted. The rate of cancer screening and cancer type were investigated between participants with and without cardiovascular disease. RESULTS: Of the 132,442 individuals, participants with cardiovascular disease had a significantly lower rate of cancer screening than those without cardiovascular disease [male: 4401 of 7972 participants (55.2%) vs. 33,744 of 52,106 participants (64.8%), p < 0.001; female: 2500 of 4984 participants (50.2%) vs. 41,319 of 67,380 participants (61.3%), p < 0.001]. The rate of cancer screening was significantly lower in participants with cardiovascular disease than in those without cardiovascular disease, regardless of cancer type, including gastric, colorectal, lung, breast, and gynecologic cancer screening. A history of cardiovascular disease was a negative factor for cancer screening (odds ratio 0.71, 95% confidence interval 0.67-0.74 in male participants; odds ratio 0.80, 95% confidence interval, 0.75-0.85 in female participants). CONCLUSIONS: The rate of cancer screening in elderly participants with cardiovascular disease was lower than that in participants without cardiovascular disease. Physicians should raise awareness regarding early cancer detection in patients with cardiovascular disease.

Plaque characteristics and prognosis in patients with peripheral arterial disease by angioscopic analysis.

BACKGROUND: The plaques with higher grade of yellow color by angioscopy are reported to be associated with vulnerability leading to adverse outcomes in coronary artery diseases. However, no studies have been performed for peripheral artery disease (PAD). We aimed to evaluate the relationship of angioscopic findings of peripheral arteries with the long-term prognosis. METHODS: Angioscopy of iliac or femoropopliteal artery was performed before endovascular therapy in patients with PAD. The local plaque color and presence of thrombus were evaluated. Multivariable Cox regression models were used to estimate hazard ratio (HR) for all-cause mortality or major adverse cardiovascular event (MACE) related to the plaque colors as well as presence of thrombus. RESULTS: Among 67 patients, 49.3% had intensive yellow plaques (group H) and the rest had light yellow to yellow ones (group L). Thrombus was detected in 74.6% of the patients and the presence was not different between the two groups. In Kaplan-Meier analysis during a median follow-up of 976 days and 757 days, group H showed increased mortality and MACE compared with group L (p <0.01 for both). Multivariable analysis demonstrated that the intensive yellow color of plaque was independently associated with mortality and MACE [HR: 11.48, 95% confidence interval (CI): 2.19-211.1 and HR: 3.81, 95% CI: 1.36-13.48, respectively] after adjusting for the presence of thrombus. CONCLUSIONS: The yellow color intensity in local plaques by angioscopy may be a novel predictor of long-term prognosis in patients with PAD, regardless of the presence of thrombus.

Effectiveness of hearing aids in treating patients with chronic tinnitus with average hearing levels of <30 dBHL and no inconvenience due to hearing loss.

BACKGROUND: The effectiveness of hearing aids for tinnitus patients without hearing loss in conversation-comprehension range and inconvenience in daily communication is unknown. OBJECTIVE: We aimed to evaluate their therapeutic effect. MATERIALS AND METHODS: We included 91 patients with average hearing levels <30 dBHL. To determine the effects, self-reported questionnaires were used. Data were collected at the entry and 3 months (n = 91) and 1 year (n = 70) after treatment initiation. RESULTS: All scores (mean ± standard deviation) decreased significantly (p < 0.0001) from before treatment to 3 months and 1 year after treatment: tinnitus handicap inventory score: from 56 ± 21 to 17 ± 17 and 13 ± 15; visual analogue scale (VAS) score for tinnitus loudness: from 71 ± 20 to 31 ± 26 and 28 ± 29; VAS score for tinnitus annoyance: 79 ± 20 to 27 ± 25 and 26 ± 30, respectively. Approximately 90% of patients noticed improvements in tinnitus annoyance and loudness, as determined by the questionnaires regarding subjective symptom improvement. CONCLUSIONS: Hearing aids may be useful for tinnitus patients without hearing loss and inconvenience in daily communication. SIGNIFICANCE: Our findings provide a treatment option for tinnitus patients with an average hearing level of <30 dBHL.
