Transradial PCI and Same Day Discharge.

Curr Treat Options Cardiovasc Med

February 2018

Gagnon Cardiovascular Institute, Morristown Medical Center, Morristown, NJ, 07960, USA.

Purpose Of Review: The evolution of cardiac catheterization has led to the development of well-refined, more effective, and safer devices that allow cardiovascular interventionalists to deliver high-quality percutaneous interventions (PCI). Transradial PCI (TRI) has gained more popularity in the USA over the past 10 years, and as experience and volume of TRI grow, studies adopting same day radial PCI protocols have emerged and are showing promising results. We sought to review the current literature on TRI and same day discharge (SDD).

Background: There is a paucity of data from large contemporary cohorts of patients with in-stent restenosis (ISR) treated with drug-eluting stents (DESs), and no studies have examined the impact of high platelet reactivity (HPR) on the occurrence of ischemic events after ISR percutaneous coronary intervention (PCI) with DESs. We sought to report outcomes after PCI of ISR lesions and its association with HPR.

Methods: Patients in the prospective, multicenter ADAPT-DES study were stratified according to whether they had ISR versus non-ISR PCI.

Accurate quantification of regurgitant volume is a central component to the management of mitral regurgitation. Cardiac magnetic resonance imaging (CMR) accurately quantifies mitral regurgitation as the difference between left ventricular stroke volume and forward stroke volume using steady state free precession and phase contrast imaging. The CMR measurement of mitral regurgitant volume is reproducible and can quantify mitral regurgitation in patients without regard to regurgitant jet morphology, such as patients with multiple and eccentric jets.

Background: Although bifurcation percutaneous coronary intervention (PCI) is associated with lower procedural success rates and higher risk of complications, there are little data regarding outcomes after successful bifurcation PCI with contemporary stents and techniques. Whether residual platelet reactivity (PR) affects outcomes differently after bifurcation versus non-bifurcation PCI is also unknown. We studied the association between bifurcation PCI, PR, and clinical outcomes among patients undergoing successful PCI with drug-eluting stents.

Aims: In patients with aortic stenosis (AS), risk stratification for aortic valve replacement (AVR) relies mainly on valve-related factors, symptoms and co-morbidities. We sought to evaluate the prognostic impact of a newly-defined staging classification characterizing the extent of extravalvular (extra-aortic valve) cardiac damage among patients with severe AS undergoing AVR.

Methods And Results: Patients with severe AS from the PARTNER 2 trials were pooled and classified according to the presence or absence of cardiac damage as detected by echocardiography prior to AVR: no extravalvular cardiac damage (Stage 0), left ventricular damage (Stage 1), left atrial or mitral valve damage (Stage 2), pulmonary vasculature or tricuspid valve damage (Stage 3), or right ventricular damage (Stage 4).

The Zena and Michael A. Wiener Cardiovascular Institute, Icahn School of Medicine at Mount Sinai, New York, NY, USA; Clinical Trials Center, Cardiovascular Research Foundation, New York, NY, USA.

Background: Whether the consequences of diabetes mellitus (DM) are worse for women than for men treated with drug-eluting stents (DES) and antiplatelet therapy remain unclear.

Methods: Patients from the Assessment of Dual Antiplatelet Therapy With Drug-Eluting Stents study were stratified according to sex and DM status. We investigated the sex-specific effect of DM on high on-clopidogrel platelet reactivity (HPR), defined as a P2Y reaction units ≥208, and the adjusted association of DM on the 2-year risk for coronary thrombotic events (CTE), defined as spontaneous myocardial infarction or definite or probable stent thrombosis.

Statin use is associated with enhanced pharmacodynamic response to clopidogrel in patients with stable coronary artery disease undergoing percutaneous coronary intervention (PCI). However, the impact of statin therapy on clopidogrel response profiles in patients with acute coronary syndrome (ACS) undergoing PCI has not been established and represents the objective of this investigation. On-treatment P2Y platelet reactivity was measured using the vasodilator stimulated phosphoprotein (VASP) phosphorylation assay before PCI, at hospital discharge, and at 1 month after PCI in ACS patients enrolled in the multicenter, prospective GEne polymorphisms, Platelet Reactivity, and Syntax Score (GEPRESS) study (n = 962).

Patients at high risk of thrombotic events after percutaneous coronary intervention (PCI) may potentially benefit from intensified antiplatelet therapy. However, more potent antiplatelet therapy would be expected to only overcome risk that is mediated by high platelet reactivity (PR). We used mediation analysis to determine the contribution of residual PR to the 2-year risk of major adverse cardiac events (MACE; the composite of cardiac death, myocardial infarction, or stent thrombosis) associated with clinical risk factors after PCI with drug-eluting stents (DES) in 8,374 patients from the prospective, multicenter Assessment of Dual AntiPlatelet Therapy with Drug-Eluting Stents (ADAPT-DES) registry.

Cardiovascular positron emission tomography (PET) imaging provides high-quality visual and quantitative myocardial perfusion and function images. In addition, cardiovascular PET can assess myocardial viability, myocardial inflammatory disorders such as cardiac sarcoid, and infections of implanted devices including pacemakers, ventricular assist devices, and prosthetic heart valves. As with all nuclear cardiology procedures, the benefits need to be considered in relation to the risks of exposure to radiation.

Stress Testing in Asymptomatic Aortic Stenosis.

Circulation

May 2017

From Clinical Trials Center, Cardiovascular Research Foundation, New York (B.R., D.B., M.B.L., P.G.); Sahlgrenska University Hospital, Gothenburg, Sweden (B.R.); Pulmonary Hypertension and Vascular Biology Research Group, Laval University, Québec, Canada (P.P.); Gagnon Cardiovascular Institute, Morristown Medical Center, NJ (L.D.G., P.G.); Columbia University Medical Center, New York (D.B., M.B.L., P.G.); Leiden University Medical Center, The Netherlands (J.J.B.); Structural Heart and Valve Center, Vanderbilt University Medical Center, Nashville, TN (B.R.L.); Northwestern University Feinberg School of Medicine, Chicago, IL (R.O.B.); Brigham and Women's Hospital, Harvard Medical School, Boston, MA (P.T.O.); and Hôpital du Sacré-Coeur de Montréal, Université de Montréal, Québec, Canada (P.G.).

Aortic stenosis is 1 of the most common heart valve diseases among adults. When symptoms develop, prognosis is poor, and current guidelines recommend prompt aortic valve replacement. Depending of the severity of the aortic stenosis and the presence of concomitant heart disease and medical comorbidities, stress testing represents a reasonable strategy to help better risk stratify asymptomatic patients.
