Filter by:The primary purpose of this randomized controlled trial s to investigate whether surgical reduction of palatine tonsils (tonsillotomy) is a superior treatment compared to complete surgical removal of palatine tonsils (tonsillectomy) in adults patients with obstructive sleep apnea and concomitant enlarged tonsils in regards of perioperative and postoperative morbidity.
This study is a prospective, single-center, single-group design exploratory clinical research. No control group is set, and only subjects meeting the indications of the study device are treated. After patients sign informed consent, they are screened, and those meeting the inclusion criteria are enrolled. The treatment involves using myocardial radiofrequency ablation system and catheter-based myocardial radiofrequency ablation needle and its guidance system for treating obstructive hypertrophic cardiomyopathy. All subjects are followed up before discharge, and at 30 days, 3 months, 6 months, and 12 months postoperatively.
The purpose of this study is to evaluate the AI-ECG algorithm for HCM in detecting HCM and in differentiating it from athlete's heart using not only the standard 12-lead ECG, but also ECGs obtained with the Apple Watch and Alivecor KardiaMobile devices.
Hypertrophic cardiomyopathy (HCM) is a common clinical genetic-related disease, with a global incidence of 0.2%-0.5%, but only a few cases (10-20%) have been clinically diagnosed. About 70% of them are hypertrophic obstructive cardiomyopathy (HOCM), these HOCM patients have significant clinical symptoms, including progressively increasing fatigue, angina, exertional dyspnea, and syncope. Conservative medications are used to treat the vast majority of patients. Invasive therapy, which includes surgical myectomy, percutaneous transluminal septal myocardial ablation(PTSMA), percutaneous intramyocardial septal radiofrequency ablation (PIMSRA) and percutaneous endocardial septal radiofrequency ablation (PESA) is introduced to patients with refractory symptoms or drug resistance. However, surgical operations are complicated and high risk procedures with high mortality. Interventional approaches are very difficult to perform and therefore the application is limited. Previous researches have shown that interventricular septal radiofrequency ablation could effectively reduce the left ventricular outflow tract pressure gradient (LVOTG), thereby treating obstructive hypertrophic cardiomyopathy (HOCM). This device is based on the same radiofrequency ablation energy principle, however, the catheter is introduced into the right ventricle and performs ablation treatment on the hypertrophic interventricular septum, which is potentially a lower risk route of access for septal ablation than currently attempted interventional approaches. The purpose of this study is to evaluate the safety and efficacy of percutaneous intramyocardial septal ablation catheters in the treatment of obstructive hypertrophic cardiomyopathy.
Background: Some people have a condition in which the wall (septum) that separates the two main pumping chambers of the heart is too thick. This thick septum causes a condition called "left ventricular outflow tract obstruction" (LVOTO), which reduces blood flow out of the heart. LVOTO can cause serious heart disease; symptoms may include shortness of breath, chest pain, heart failure, or death. Researchers want to find better ways to treat LVOTO. Objective: To test a new procedure where excess tissue is sliced away from the septum in people with LVOTO. This procedure is called "septal scoring along midline endocardium" (SESAME). Eligibility: Adults aged 21 years with LVOTO. Design: Participants will have baseline tests. They will have imaging scans and tests of their heart structure and function. They will take a walking test and answer questions about how their heart condition affects their life. Participants will stay in the hospital 2 to 6 days for the SESAME procedure. They will be completely or partially asleep for the procedure. A tube will be inserted into the mouth and down the throat to take pictures of the heart. Pictures may also be taken with a tube inserted inside the heart. Next, tubes will be inserted into the groin and guided through the blood vessels up to the heart. Guidewires will be inserted into the heart. Doctors will watch the path the wires take with x-rays and ultrasound. When the wire is in the correct place, it will be electrified to slice excess tissue away from the septum. Participants will have 3 follow-up visits within 1 year.
Tonsillectomy ± adenoidectomy (T&A) is one of the most common surgical operations with over 500,000 pediatric T&As performed annually in the United States. Unfortunately, despite advances in anesthetic and surgical techniques, moderate-severe post-tonsillectomy pain (PTP) remains a significant problem affecting up to 62% of children. PTP is thought to arise from pharyngeal mucosal inflammation, which produces local nerve irritation and pharyngeal muscle spasm. Patient factors and surgical techniques also play major roles. Race is an important phenotypic risk factor for moderately severe early PTP. The underlying molecular basis of this differential pain experience is presently unknown. This gap in knowledge means that therapies are poorly targeted and often unsuccessful. Indeed, treatment options for PTP have not advanced substantively for many years. Metabolomics provides novel opportunities to investigate common and unique "metabolic signature" of PTP through the analysis of low molecular weight compounds produced in response to tissue injury. Therefore, the central themes of this proposal are that (1) PTP is a complex process that may be determined by molecular level factors such as preoperative systemic inflammation and metabolic profile, and (2) these molecular level factors may explain the excess burden of PTP among minority children. Here the investigators seek to utilize a combined clinical, biological and untargeted metabolomics approach to identify candidate small and large serum molecules that may influence the frequency and severity of PTP in children across racial groups. This approach to exploring the molecular basis of PTP is novel and knowledge from the study should substantially enhance understanding of the mechanisms underlying pediatric PTP - and narrow the racial disparities in post-operative pain.
This prospective, multicenter, single-arm objective performance criteria trial is designed to assess the efficacy and safety of the Percutaneous Endocardial Septal Radiofrequency Ablation (PESA) procedure in the treatment of obstructive hypertrophic cardiomyopathy (oHCM). The primary objectives include investigating: 1. the treatment efficacy and safety of PESA treatment in oHCM patients with either left ventricular outflow tract obstruction (LVOTO) or midventricular obstruction; 2. the impact of PESA treatment on the functional capacity, quality of life and long-term prognosis of oHCM patients with either LVOTO or midventricular obstruction.
The aim of this study is to determine whether the distribution of internal load predicts the distribution of muscle hypertrophy among hamstring heads after a 10-week resistance exercise program. The hypothesis is that the distribution of internal muscle load among the hamstring is related to the distribution of muscle hypertrophy.
The purpose of this observational post-marketing surveillance study is to assess the real-world safety of mavacamten for the treatment of symptomatic obstructive hypertrophic cardiomyopathy (oHCM) in adult participants in Korea. Participants who will receive at least 1 dose of mavacamten will be enrolled.
