Pacing strategy study for certain heart failure patients
This trial tests a pacing approach designed to improve how the heart beats in some people with heart failure and a specific heart rhythm pattern on ECG. If you already need a device (CRT-D) based on your results, the study may help see whether this pacing correction improves outcomes.
Phoenix, ArizonaAges 18 years+ - NCT05564689Recruiting
Tests coronary blood flow in heart failure patients with CRT
This study measures how well blood flows in the heart (coronary flow) in people with heart failure with reduced pumping strength and a specific heart rhythm problem called left bundle branch block. It focuses on people who already have a cardiac resynchronization therapy (CRT) device and have stable treatment, to see how coronary flow relates to their heart condition.
AalborgAges 18 years+ - NCT06469073Recruiting
Nerve block for pain after heart valve surgery
This study tests a special nerve block (ultrasound-guided) to see if it can better control pain after heart valve replacement surgery. It may help you recover more comfortably if you are having your first mitral or aortic valve replacement.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT06878391Recruiting
Shoulder nerve blocks for rotator cuff repair surgery
This trial tests whether adding specific nerve blocks and a patient-controlled pain pump improves pain control after arthroscopic rotator cuff repair. It may help people who are having this surgery feel better and use less pain medicine.
Chuncheon, Gangwon-doAges 20 years+ - NCT06055751Recruiting
Heart rhythm monitoring after aortic valve replacement
This trial studies people who had a heart valve procedure called TAVI and later had a heart rhythm problem. You will get a tiny heart monitor placed under your skin to track your heart rhythm over time and help doctors understand how common these problems are.
Kansas City, MissouriAges 18 years+ - NCT06763549Enrolling by invitation
AI-powered wearable patch for heart and lung monitoring
This study tests an AI-powered wearable patch (the COR ECG) to see if it can better track heart and lung health. It may help doctors find problems earlier without needing bulky equipment.
Melbourne, FloridaAges 18 years+ - NCT05015660Recruiting
Testing left bundle pacing versus usual right pacing
This study compares a newer heart pacing method (left bundle branch pacing) to the standard method (right ventricular pacing) in people who need most of their heartbeats paced. It may help improve how well the heart pumps over time.
Montreal, QuebecAges 18 years+ - NCT06061627Recruiting
LOT-CRT vs standard CRT for heart failure with NICD
This study compares a newer pacing therapy (LOT-CRT) to standard cardiac resynchronization therapy (BiVP) for people with heart failure who have a specific type of electrical delay in the heart (NICD). The goal is to see if the newer method works better.
Nanjing, JiangsuAges 18–80 - NCT05519046Recruiting
Test a heart pacing treatment for Chagas-related heart failure
This study looks at a heart treatment called cardiac contractility modulation in people with Chagas heart disease who have moderate symptoms and weak heart pumping. It aims to see whether this therapy improves heart function and related outcomes in the right patients.
São Paulo, São PauloAges 18–75 - NCT05774262Recruiting
Pacemaker or nerve-targeting treatment for certain heart rhythm blocks
This study compares two treatments for specific “AV block” heart rhythm problems: a pacemaker versus a procedure called cardioneuroablation. The goal is to see which approach works better for preventing symptoms like fainting or slow heart rates.
Dąbrowa GórniczaAges 18–75 - NCT05769036Recruiting
Biventricular vs left bundle pacing for heart failure outcomes
This trial compares two types of heart pacing to see which improves outcomes for people with heart failure. It may help those who need pacing to better coordinate heartbeats and relieve symptoms.
TomskAges 18–80 - NCT06652750Recruiting
5G cloud-based check-up for heart device patients
This study tests whether a 5G-based remote check-up (over the cloud) is safe and effective for people with certain implanted heart devices, like pacemakers. You'll skip your first clinic visit and instead use a video call or remote check to see how your device is doing.
Guangzhou, GuangdongAges 18 years+ - NCT07588230Recruiting
Nerve Block for Minimally Invasive Heart Valve Surgery Pain
This study tests a targeted nerve block (pain-numbing injection) to help manage pain after minimally invasive heart valve surgery. Researchers want to see if this technique reduces pain and the need for opioid medications during recovery.
