Davos, Kanton GraubündenAges 18 years+ - NCT07103733Recruiting
Adding MRI and monitoring to mitral valve repair study
This study is for people already in the PRIMARY trial who are having mitral valve repair surgery. It adds an extra MRI scan and possibly a heart rhythm monitor to learn more about heart recovery after repair.
Los Angeles, CaliforniaAges 60 years+ - NCT07109141Recruiting
Registry of Heart Rhythm Fix Procedures Using Pulsed Field Ablation in Poland
This study tracks people who have a procedure called pulsed field ablation to fix an abnormal heart rhythm (atrial arrhythmia). It's a registry, meaning researchers will collect information to learn more about how well the treatment works and how safe it is.
Wroclaw, Lower Silesian VoivodeshipAges 18 years+ - NCT07116525Recruiting
Study of heart mapping for abnormal rhythms
This trial tests a special catheter to map abnormal heart rhythms like ventricular tachycardia or atrial fibrillation. It may help patients who need a procedure to find and treat the source of these fast or irregular heartbeats.
BrugesAges 18 years+ - NCT07174206Recruiting
Smartwatch monitoring for heart patients
This trial tests a smartwatch tool to track heart rhythm and detect problems in people with heart disease. It may help find irregular heartbeats early during routine checkups.
São Paulo, São PauloAges 22 years+ - NCT07181590Recruiting
Balloon-based ablation for atrial fibrillation: post-approval study
This trial tests a balloon catheter that uses pulsed field energy to treat atrial fibrillation (AF) in people who have tried medication without success. It aims to see how well it works in real-world use.
LinzAges 18 years+ - NCT07271238Recruiting
Study of a new imaging system for heart ablation
This study tests a new imaging system (VERAFEYE) that helps doctors guide catheter ablation, a procedure to fix irregular heartbeats like atrial fibrillation. It aims to see if the system makes the procedure safer or more effective.
SplitAges 18 years+ - NCT07336225Recruiting
CMR Study for Heart Device Patients
This study looks at people who already had a heart MRI before getting a pacemaker, defibrillator, or other heart device. It aims to learn how MRI results might predict long-term outcomes for these patients.
BeijingAges 18 years+ - NCT06299514Recruiting
Pacemaker and ablation for heart failure with atrial fibrillation
This trial tests if a pacemaker plus an ablation procedure can improve heart failure symptoms in people with atrial fibrillation. It is for those with moderate to severe heart failure who are already on the right medications.
Victoria, British ColumbiaAges 18 years+ - NCT07374263Recruiting
Do heart rhythm drugs pose risks in hospital?
This study looks at whether certain medications that can affect heart rhythm (QT-prolonging drugs) are linked to serious heart problems in adults who were hospitalized. It includes patients admitted to St. Joseph's Healthcare Hamilton or other GEMINI hospitals between 2017 and 2025.
Hamilton, OntarioAges 18 years+ - NCT07388108Recruiting
Predicting heart rhythm problems after heart surgery
This trial studies whether measuring how the upper chambers of the heart work together can help predict dangerous heart rhythms after heart surgery. If you are in normal heart rhythm and not having mitral valve surgery, this study may help doctors better prevent complications.
Mendoza, MendozzAges 18–80 - NCT00138931Recruiting
Study genetics of inherited heart and muscle conditions
This study looks at genetic causes of inherited heart (cardiovascular) and muscle/nerve (neuromuscular) conditions. You may be asked about your family history and possibly genetic samples to help connect symptoms to specific genetic changes.
