Valve Heart Disease

Cardiovascular disease (CVD) is the leading cause of global morbidity and mortality, with its prevalence increasing significantly from 1990 to 2019. Establishing a comprehensive cardiac surgery database is crucial for exploring perioperative prognostic factors and improving clinical outcomes. This muti-center, prospective observational study aims to construct a prospective cohort database for perioperative cardiac surgery. We plan to enroll adult patients who undergo cardiac surgery with cardiopulmonary bypass at the Second Affiliated Hospital of Zhejiang University and other hospitals from May 1, 2026 to December 31, 2031. Multi-dimensional perioperative data, including laboratory tests, hemodynamics, intraoperative echocardiography, and perioperative medications, will be collected and integrated, along with epidemiological data, clinical diagnosis and treatment information, multimodal data, and follow-up outcomes. An interconnected big data sharing platform will also be built. This database will provide a valuable resource for multi-level researches such as perioperative risk assessment, individualized prevention, precise diagnosis and treatment, and therapeutic efficacy monitoring. It will also help optimize surgical and perioperative management, improve the quality of cardiac surgery, and provide evidence for the refinement of China's healthcare system, ultimately enhancing perioperative safety and rehabilitation efficiency of patients.

After deciding to join this study and signing the informed consent form, participants will undergo the following interventions: All participants will receive a preoperative assessment (Tp) before surgery. Within five days after transferring from the ICU to the general ward, participants will receive a baseline assessment (T0). After completing seven sessions of myofascial release (MFR), a post-intervention assessment (T1) will be conducted. Assessments include maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), pulmonary function tests, mid- and lower-thoracic mobility, surface electromyography (sEMG) to measure diaphragmatic and sternocleidomastoid muscle activity, and pain scores. Pulmonary function tests include forced vital capacity (FVC), forced expiratory volume in one second (FEV1), FEV1/FVC ratio, and maximum voluntary ventilation (MVV). Participants will be randomly assigned to an intervention group or a control group. The intervention group will receive myofascial release therapy in addition to routine physical therapy in the general ward. Routine therapy includes daily physical therapy sessions such as out-of-bed activities, incentive spirometry training (Triflow), and functional exercises. The MFR intervention consists of three steps: The therapist places both hands on the thoracic outlet, with the index and middle fingers above the clavicle. One hand is placed on the anterior chest and the other hand parallel on the participant's back. Both hands are placed on the anterolateral region of the thoracoabdominal diaphragm. During each step, participants are instructed to take 10 slow, deep breaths and direct airflow toward the therapist's hands. Each session lasts approximately 15 minutes, once daily, for seven sessions. The control group will receive only routine physical therapy (out-of-bed activities, incentive spirometry, and functional exercises) without additional myofascial release therapy.

To explore predictors of major cardio-vascular events after cardiac surgery and trans-catheter valve implantation with a specific interest in studying mechanisms linking pre-operative leukocyte, fat and myocardial phenotypes with post-intervention outcomes.

The purpose of the study is to compare the various 2D and 3D methods of valvular heart disease quantification (Doppler, PISA, VCA, volumetric method) and strain with cardiac magnetic resonance (CMR) measurements of left and right ventricular systolic function strain and myocardial fibrosis assessment.

Heart Failure and valvular heart disease are disproportionate problems in rural and remote Australia (RRA). Echocardiography is the best imaging investigation, and essential for management, but access to this essential test shows huge geographic variations, primarily because of dependence on expert acquisition. This trial seeks to demonstrate the effectiveness of artificial intelligence-based echocardiography for triage and management of patients with known or suspected heart disease in RRA.

The FRAILTY-CARDIOWATCH study is investigating how well the Corsano CardioWatch 287-2, a wrist-worn medical device, can classify frailty in patients. Frailty is a condition often seen in older adults, characterized by decreased strength, endurance, and overall health, which can make individuals more vulnerable to illness or injury. The goal of this study is to develop an algorithm that can accurately assess frailty using the device. In phase 1 of the study, data will be collected from patients aged 70 or older who are scheduled for heart-related procedures, such as valve replacements or pacemaker implantation. The study aims to compare the frailty classifications of the CardioWatch with two established methods: the Geriatric 8 (G8) questionnaire and the FRAIL scale. It will also compare the CardioWatch with the 6-minute walk test. Patients will wear the CardioWatch for six days-three days before their procedure and three days after-and complete the G8, FRAIL, and 6-minute walk tests. The collected data will help develop and train the frailty classification algorithm. The main focus is to evaluate how well the frailty classifications from the CardioWatch match those from the other tests. This research could potentially lead to a more accurate and continuous way to monitor frailty in patients using wearable technology.

The goal of this observational study is to characterize the population of patients qualified for transcatheter tricuspid valve interventions (TTVI). It is expected to: * Describe the profile of patients qualified for TTVI * Establish the most common causes for disqualification from TTVI * Evaluate the immediate and long-term efficacy of TTVI * Evaluate TTVI safety Participants will undergo a standard qualification procedure for TTVI and then will be subject to a follow-up consisting of clinical examination, echocardiography and laboratory testing.

Valves will be taken from hearts donated by organ donors, and implanted into patients who need a new heart valve.

This prospective, randomized controlled study is aimed to figure out suitable transfusion threshold in patients undergoing cardiac valve surgery under cardiopulmonary bypass(CPB). Patients are randomly assigned to restrictive and liberal transfusion group and receive blood transfusion during and after surgery. Compare primary and secondary outcomes of two groups.
