During a TIPS procedure, a shunt or stent (mesh tube) is passed down the jugular vein (the vein above the collarbone in the neck) using fluoroscopy (real time x-rays) guidance. The stent then is inserted between the portal vein (vein that carries blood from the intestines into the liver) to a hepatic vein (vein that carries blood away from the liver back to the heart). This means that blood that would usually go to the intestinal veins is now going to the heart. Because more blood will be flowing to the heart, the heart needs to be strong enough to handle the extra volume.

REPRISE IV is a prospective, multicenter single-arm study designed to evaluate the safety and effectiveness of the LOTUS Edge Valve System for TAVR in symptomatic subjects who have severe native aortic stenosis and are considered at intermediate risk for surgical valve replacement.

Primary Investigator: Michael Salinger, MD
Subinvestigators: Peter Mason, MD; Paul Pearson, MD; Joshua Meskin, MD

ClinicalTrials.gov Identifier: NCT03618095
Status: Currently Enrolling

The purpose of the study is to assess the feasibility of treating peripheral arterial disease (PAD) with a drug coated balloon along with removal of the plaque using the JetStream XC atherectomy system when compared to a drug coated balloon only. Arteries are reassessed at 1 month, 6 months, 1 year, 2 year and 3 years after treatment.

ClinicalTrials.gov Identifier: NCT03206762
Status: Currently Enrolling

Evaluates the clinical efficacy and safety of the IASD System II in symptomatic heart failure patients with an LV ejection fraction ≥40%, and elevated left sided filling pressures despite standard Guideline Directed Medical Therapy (GDMT).

Primary Investigator: Michael Salinger, MD

Status: Currently enrolling

The objective of this study is to determine the safety and efficacy of transcatheter aortic valve replacement (TAVR) via a transfemoral approach in HF patients with moderate aortic stenosis (AS) compared with optimized heart failure therapy (OHFT).

Status: Currently enrolling

Determine if the use of imaging-guided endovascular therapy (EVT) is an effective strategy with which to reduce Post-Thrombotic (PTS) disease severity and improve quality of life (QOL) in patients with established disabling iliac-obstructive post-thrombotic syndrome (DIO-PTS).

Primary Investigator: Eric J. Hohenwalter, MD, FSIR

Status: Currently enrolling

To determine whether daily supplementation with the probiotic Lactobacillus plantarum 299v improves the function of blood vessels in patients with coronary artery disease.

Primary Investigator: Michael Widlansky, MD, MPH

Status: Open to enrollment 

The purpose of this study is to evaluate whether the 50cc TAH-t can support patients who are imminent risk of death from biventricular heart failure, are eligible for heart transplantation, and for whom the 70cc TAH-t is not appropriate due to size of the chest cavity.

Primary Investigator: David Joyce, MD
Sub-investigators: Lyle Joyce, MD, PhD; Lucian Durham, MD, PhD; Paul Pearson, MD, PhD; Chris Rokkas, MD

The purpose of this study is to assess among patients with an acute myocardial infarction and a hemoglobin concentration less than 10 g/dL, if a liberal transfusion strategy with a threshold of 10 g/dL reduces the rate of the composite outcome of all-cause mortality or recurrent nonfatal acute myocardial infarction through 30 days following randomization compared to a restrictive transfusion strategy with a threshold of 7 to 8 g/dL.
