Right ventricular dysfunction

In pulmonary arterial hypertension, the right side of the heart works against high pressure in the lungs and can weaken over time. This study tests whether temporary pacing of the right ventricle at the spot where it contracts latest can improve its pumping strength. Researchers …

This study tests whether giving two inhaled drugs (milrinone and epoprostenol) before heart-lung bypass can prevent difficult separation from the machine. About 141 adults having heart surgery will be randomly assigned to receive the drug combo or a placebo. The goal is to see if…

This study is testing whether valsartan, a drug already used for high blood pressure, can help people with pulmonary arterial hypertension (PAH). Researchers will give 60 adults either valsartan or a placebo for 24 weeks to see if it improves how far they can walk in six minutes …

This phase 2 trial is testing whether two existing drugs, empagliflozin (used for diabetes) and ranolazine (used for chest pain), can improve right heart function in 30 people with pulmonary hypertension and right heart failure. Participants will receive one of the drugs plus sta…

This study will compare two newer pacemaker technologies—left bundle branch area pacing and leadless pacing—to see how they affect heart function and the tricuspid valve. Twenty adults with certain heart block conditions will receive both types temporarily during their routine pa…

This observational study looks at how the right side of the heart adapts when critically ill patients receive fluids. Researchers will use ultrasound to measure heart function before and after fluid administration in 100 adults. The goal is to understand why some patients develop…

This study looks at how the right side of the heart works in people with COPD, both at rest and during different levels of exercise. Researchers want to find patterns of heart strain to help develop better treatments in the future. About 60 adults aged 40 and older with COPD will…

This study looks at how implantable heart devices like pacemakers, ICDs, and CRT devices may affect the right side of the heart. Researchers will check 40 adults before and 6 months after device placement using heart scans, ultrasound, and a blood test. No experimental treatment …
