Circ Cardiovasc Interv 2018 Jul;11(7):e006676

Department of Cardiovascular Medicine, Tsuchiura Kyodo General Hospital, Ibaraki, Japan (Y. Kanaji, T.Y., R.H., T.M., E.U., M. Hoshino, M.Y., M. Hada, Y. Kanno, T.F., H.O., Y.S., A.S., T.L., T.K.).

Background: Few studies have documented changes in global absolute coronary blood flow and global coronary flow reserve after percutaneous coronary intervention (PCI) in relation to regional physiological measures. Phase-contrast cine-magnetic resonance of the coronary sinus is a promising approach to quantify global absolute coronary blood flow. We aimed to assess the impact of elective PCI on global absolute coronary blood flow and global coronary flow reserve by quantifying coronary sinus flow (CSF) using phase-contrast cine-magnetic resonance in relation to regional physiological indices.

Unmasking Myocardial Bridge-Related Ischemia by Intracoronary Functional Evaluation.

Circ Cardiovasc Interv 2018 Jun;11(6):e006247

From the Department of Cardiac, Thoracic and Vascular Sciences, Padova University Hospital, Italy.

Background: Invasive physiological assessment of myocardial bridges (MBs) is largely unsettled. Unlike fractional flow reserve (FFR), instantaneous wave-free ratio (iFR) is a diastole-specific index. As such, its value might not be hampered by systolic pressure overshooting and negative systolic pressure gradient caused by the compression of the tunneled coronary artery. Read More

Coronary Embolus: An Underappreciated Cause of Acute Coronary Syndromes.

JACC Cardiovasc Interv 2018 01;11(2):172-180

Department of Cardiovascular Diseases, Mayo Clinic, Rochester, Minnesota. Electronic address:

Coronary embolism is the underlying cause of 3% of acute coronary syndromes but is often not considered in the differential of acute coronary syndromes. It should be suspected in the case of high thrombus burden despite a relatively normal underlying vessel or recurrent coronary thrombus. Coronary embolism may be direct (from the aortic valve or left atrial appendage), paroxysmal (from the venous circulation through a patent foramen ovale), or iatrogenic (following cardiac intervention).

Intracoronary Optical Coherence Tomography 2018: Current Status and Future Directions.

JACC Cardiovasc Interv 2017 12;10(24):2473-2487

Center for Interventional Vascular Therapy, Division of Cardiology, Presbyterian Hospital and Columbia University, New York, New York; Cardiovascular Research Foundation, New York, New York.

The advent of intravascular imaging has been a significant advancement in visualization of coronary arteries, particularly with optical coherence tomography (OCT) that allows for high-resolution imaging of intraluminal and transmural coronary structures. Accumulating data support a clinical role for OCT in a multitude of clinical scenarios, including assessing the natural history of atherosclerosis and modulating effects of therapies, mechanisms of acute coronary syndromes, mechanistic insights into the effects of novel interventional devices, and optimization of percutaneous coronary intervention. In this state-of-the-art review, we provide an overview of the published data on the clinical utility of OCT, highlighting the areas that need further investigation and the current barriers for further adoption of OCT in interventional cardiology practice.

ACIST-FFR Study (Assessment of Catheter-Based Interrogation and Standard Techniques for Fractional Flow Reserve Measurement).

Circ Cardiovasc Interv 2017 Dec;10(12)

From the Stanford University School of Medicine, Department of Medicine, Stanford Cardiovascular Institute, CA (W.F.F., C.S., L.Y., M.D.); Mercy Medical Center, Coon Rapids, MN (J.W.C.); Tibor Rubin VA Medical Center, Long Beach, CA (A.H.S.); Lindner Center for Research and Education, The Christ Hospital, Cincinnati, OH (I.J.S.), University of Minnesota, Minneapolis (G.R.); St. Francis Hospital, Roslyn, NY (A.J.); Cardiovascular Research Foundation, New York, NY (A.J.); and Scripps Clinic, La Jolla, CA (M.J.P.).

Background: Measurement of fractional flow reserve (FFR) to guide coronary revascularization lags despite robust supportive data, partly because of the handling characteristics of traditional coronary pressure wires. An optical pressure-monitoring microcatheter, which can be advanced over a traditional coronary guidewire, facilitates FFR assessment but may underestimate pressure wire-derived FFR.

Methods And Results: In this prospective, multicenter trial, 169 patients underwent FFR assessment with a pressure wire alone and with a pressure microcatheter over the pressure wire. Read More

Circ Cardiovasc Interv 2017 Oct;10(10)

From the Stanford University Medical Center, CA (T.N., Y.K., D.-H.C., W.F.F.); Stanford Cardiovascular Institute, CA (T.N., Y.K., D.-H.C., W.F.F.); University of Texas Medical School and Memorial Hermann Hospital, Houston (N.P.J., K.L.G.); Cardiovascular Center Aalst, Belgium (B.D.B.); West of Scotland Heart and Lung Center, Golden Jubilee National Hospital, Clydebank, Scotland (C.B., K.G.O.); British Heart Foundation Glasgow Cardiovascular Research Center, Institute of Cardiovascular and Medical Sciences, University of Glasgow, Scotland (C.B.); Division of Cardiovascular Medicine, Stony Brook University Medical Center, NY (A.J.); Cardiovascular Research Foundation (CFR), New York, NY (A.J.); Catharina Hospital, Eindhoven, the Netherlands (N.H.J.P.); and Eindhoven University of Technology, the Netherlands (N.H.J.P.).

Background: Contrast fractional flow reserve (cFFR) is a method for assessing functional significance of coronary stenoses, which is more accurate than resting indices and does not require adenosine. However, contrast media volume and osmolality may affect the degree of hyperemia and therefore diagnostic performance.

Methods And Results: cFFR, instantaneous wave-free ratio, distal pressure/aortic pressure at rest, and FFR were measured in 763 patients from 12 centers. Read More

Role of Proximal Optimization Technique Guided by Intravascular Ultrasound on Stent Expansion, Stent Symmetry Index, and Side-Branch Hemodynamics in Patients With Coronary Bifurcation Lesions.

Circ Cardiovasc Interv 2017 Oct;10(10)

From the Division of Cardiology, University of Alabama at Birmingham (D.H., A.C., O.A., J.T., A.S., M.A.L.); Suez Canal University, Ismailia, Egypt (D.H.); and Medtech Research Theme, National Heart Centre Singapore and Duke-NUS Medical School (N.F.).

Background: Bench models of coronary bifurcation lesions demonstrated that the proximal optimization technique (POT) expanded the stent and opened the side branch (SB). We investigated the role of POT guided by intravascular ultrasound on the main vessel (MV) stent expansion and SB fractional flow reserve (FFR) in patients with coronary bifurcation lesion.

Methods And Results: In 40 patients with coronary bifurcation lesion, 120 intravascular ultrasound examinations of the MV were performed at baseline, after MV stenting, and POT followed by 95 FFR measurements of the SB. Read More

Effect of Elective Percutaneous Coronary Intervention on Hyperemic Absolute Coronary Blood Flow Volume and Microvascular Resistance.

Circ Cardiovasc Interv 2017 Oct;10(10)

From the Department of Cardiovascular Medicine, Tsuchiura Kyodo General Hospital, Japan (Y.K., T.M., T.Y., E.U., M.A., J.M., M.H., M.Y., T.N., M.H., S.I., R.H., Y.K., T.K.) and Department of Cardiovascular Medicine, Tokyo Medical and Dental University, Japan (M.I.).

Background: The hemodynamics involved in the relationship between absolute coronary blood flow (ABF) volume and myocardial resistance (MR) are complex, and the effect of percutaneous coronary intervention (PCI) on their changes remains unclear. The aim of this study was to investigate the differences in hyperemic ABF and MR before and after elective PCI using a thermodilution method.

Methods And Results: We investigated 28 vessels (right coronary artery, 9; left anterior descending coronary artery, 18; left circumflex coronary artery, 1) from 28 patients with stable angina pectoris undergoing elective PCI. Read More

Phase 2a Clinical Trial of Mitochondrial Protection (Elamipretide) During Stent Revascularization in Patients With Atherosclerotic Renal Artery Stenosis.

Circ Cardiovasc Interv 2017 Sep;10(9)

From the Division of Nephrology and Hypertension (A.S., S.M.S.H., A.E., C.M.F., L.O.L., S.C.T.) and Department of Radiology (J.F.G., H.B., M.A.M., S.M.), Mayo Clinic, Rochester, MN.

Background: Atherosclerotic renal artery stenosis reduces renal blood flow (RBF) and amplifies stenotic kidney hypoxia. Revascularization with percutaneous transluminal renal angioplasty (PTRA) and stenting often fails to recover renal function, possibly because of ischemia/reperfusion injury developing after PTRA. Elamipretide is a mitochondrial-targeted peptide that binds to cardiolipin and stabilizes mitochondrial function. Read More

Background: Fractional flow reserve (FFR), an index of the hemodynamic severity of coronary stenoses, is derived from invasive measurements and requires a pressure-monitoring guidewire and hyperemic stimulus. Angiography-derived FFR measurements (FFR) may have several advantages. The aim of this study is to assess the diagnostic performance and interobserver reproducibility of FFR in patients with stable coronary artery disease. Read More
