Pulmonary Vascular Hemodynamics Before and After Mitral Valve Procedures

Study Purpose

The objective of this proposal is to study circulating and echocardiographic markers of pulmonary vascular and right ventricular remodeling in patients with a WHO-2 diagnosis of pulmonary hypertension after mitral valve procedures. The investigators are proposing the study will be impactful for the early detection and prediction and of residual pulmonary hypertension (PH) that would otherwise be undetected and fatal with no curative treatment.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Unknown
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT04947384
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

The investigators will enroll 3 groups: Group 1: Patients with established WHO-2 diagnosis of PH undergoing open and interventional mitral valve procedures. Group 2: Patients with no PH undergoing open and interventional mitral valve procedures. Group 3: Patients with established diagnosis of WHO-1-4 groups of PH undergoing right heart catheterization. Groups 2 and 3 will serve as controls. All procedures will be performed at the main UAB Hospital cardiac surgical operating rooms and at the cardiac angiographic suites. The investigators will collect a total of 3 blood samples; the first sample will be obtained on arterial cannulation before the initiation of the intervention, the second sample will be collected upon the end of the procedure prior to leaving the procedure room, and the third sample will be collected on the day of discharge from the hospital. A comprehensive echocardiogram at the 3 corresponding time points of the blood samples obtained; before, and after the intervention and before discharge.

Arms & Interventions

Arms

: Patients with moderate mitral valve disease, undergoing interventions

Patients with established WHO-2 diagnosis of PH undergoing open and interventional mitral valve procedures.

: Patients undergoing mitral valve interventions without pulmonary hypertension

Patients with no PH undergoing open and interventional mitral valve procedures. This group will serve as a control.

: Patients with precapillary pulmonary hypertension scheduled for right heart catheterization

Patients with established diagnosis of WHO-1-4 groups of PH undergoing right heart catheterization. This group will serve as a control.

Interventions

Diagnostic Test: - To discern micro-RNA specific for right and left heart induced PH

While undergoing other procedures, the investigators will be collecting a total of three blood samples. The first sample will be obtained on arterial cannulation before the initiation of the intervention, the second sample will be collected upon the end of the procedure prior to leaving the procedure room, and the third sample will be collected on the day of discharge from the hospital.
