cardiac catheterization

K L Yew, Z Kang, A Anum
Coronary artery anomalies are often discovered incidentally during cardiac catheterization or computed tomography coronary angiography and may involve the affected coronary artery origin and its course. Coronary artery anomalies are associated with congenital heart disease. The affected coronary arteries may have an unusual high take off origin, origin from contralateral or non-coronary sinus, origin from the pulmonary artery, single coronary system or coronary artery fistula.

BACKGROUND: Pulmonary hypertension (PH) is a well-recognized complication of left ventricular heart failure (HF). HYPOTHESIS: Differences exist in demographic, clinical, hemodynamic, and survival characteristics of patients with left ventricular HF who have combined postcapillary and precapillary PH (CpcPH), isolated postcapillary PH, or no PH. METHODS: A secondary data analysis was conducted using a large prospective database of patients undergoing right heart catheterization from 1994 to 2012...

BACKGROUND: The surgical and procedural specialties are continually evolving their methods to include more complex and technically difficult cases. These cases can be longer and incorporate multiple teams in a different model of operating room synergy. Patients are frequently older, with comorbidities adding to the complexity of these cases. Recording of this environment has become more feasible recently with advancement in video and audio capture systems often used in the simulation realm...

Our aim was to assess the discrepancy in the blood pressure amplification (BPA) value defined as the aortic-to-brachial increase in systolic BP (SBP) between invasive and noninvasive brachial cuff-based methods. In 45 patients undergoing cardiac catheterization, BP in the brachial artery and ascending aorta were measured with an invasive catheter and a brachial cuff-based oscillometric device. To calculate aortic SBP, brachial waveforms were calibrated by the brachial systolic and diastolic BP (DBP) (C1 calibration) or by the brachial mean BP and DBP (C2 calibration)...

Validation of a medical device measuring a biomarker is a complex process, involving technical aspects (What is actually measured by the device, and how is this done ? Is the measurement reproducible ? Is there a gold standard for measurement of the particular biomarker ? If yes, how accurate and how precise are the measurements by the device, compared to the gold standard ?) and clinical aspects (Do the measurements predict outcome ? If yes, is there added value, when standard clinical parameters are considered ? Is there a treatment strategy, based on the mesurements of the novel device ? Is this strategy cost-effective ?)...

OBJECTIVE: Accurate measurement of blood pressure (BP) is crucial for hypertension management. Accuracy of brachial cuff (BCUFF) devices to measure invasive (intra-arterial) BP at the brachial artery (BINV) and aorta (AINV) has never been systematically assessed. This study aimed to determine the: 1) relationship between BINV and AINV; 2) accuracy of BCUFF devices to estimate invasive BP and; 3) accuracy of BCUFF devices to classify BP thresholds. DESIGN AND METHOD: Three individual patient meta-analyses (by search of online databases and systematic review supplemented by measurements in a tertiary hospital cardiac catheterization laboratory) were performed to determine: 1) BINV versus AINV BP; 2) BCUFF versus BINV BP and AINV BP and; 3) BCUFF for BP classification versus invasive BP...

BACKGROUND: The aim of this study was to evaluate the effect of exercise training on cardiac function in heart failure (HF) patients recently suffering from acute decompensation. Radionuclide ambulatory ventricular function monitoring (VEST) was used to detect variations in cardiac hemodynamics during training period. METHODS: This was a monocentric, randomized, controlled trial. We enrolled 72 HF patients [left ventricle ejection fraction (LVEF) <40%] within two weeks after acute cardiogenic pulmonary edema: 40 in the elderly group, 32 in the middle-aged group...

Centrifugal and axial flow left ventricular assist devices have different hydrodynamic properties that may impact the effectiveness of left ventricular unloading. We sought to determine if patients implanted with the HeartWare HVAD (HW) and HeartMate II (HMII) had a similar degree of hemodynamic support by comparing parameters measured using echocardiography and right heart catheterization. Using our prospectively collected database, we identified 268 patients implanted with the HMII and 93 with the HW. Demographic characteristics were similar between groups...

BACKGROUND: Over 1,000,000 cardiac catheterizations (CC) are performed annually in the United States. There is a small risk of complication that has persisted despite advances in technology. It is unknown whether daily CC procedural volume can influence this risk. In an effort to improve outcomes at our academic medical center, we investigated the relationship between daily CC volume and complication rates. METHODS: We obtained data from both the National Cardiovascular Data Registry (NCDR) Cath-PCI and Lumedx© databases reviewing the records of patients undergoing scheduled, non-emergent CC at our facility between January 2005 to June 2013...

Cardiac interventions often result in high radiation dose to patient's skin, so a reliable indicator in terms of a commonly used dose descriptor is required to monitor skin exposures. In the present study, Gafchromic XR-RV3 film was used to measure the peak skin dose (PSD) during 40 coronary angiography (CA) and 50 percutaneous transluminal coronary angioplasty (PTCA) procedures. Corresponding values of kerma-area product (PKA), fluoroscopy time (FT) and reference air-kerma (Ka,r) were recorded and correlated with PSD...

BACKGROUND AND AIMS: Decreased nitric oxide (NO) bioavailability and increased oxidative stress may be involved in the pathogenesis of contrast-induced acute kidney injury (CI-AKI). The relationship between asymmetric dimethylarginine (ADMA), an endogenous NO synthase inhibitor, and CI-AKI is unknown. METHODS: We measured plasma ADMA levels in 664 consecutive subjects undergoing cardiac catheterization. Mehran score for predicting the risk of CI-AKI was calculated...

Optimization of medical therapy during discharge planning is vital for improving patient outcomes after hospitalization for acute myocardial infarction (AMI). However, limited information is available about recent trends in the prescribing of evidence-based medical therapies in these patients, especially from a population-based perspective. We describe decade-long trends in the discharge prescribing of aspirin, angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, β blockers, and statins in hospital survivors of AMI...

: : Bone marrow-derived progenitor cells are mobilized into the peripheral blood after acute myocardial injury and in chronic ischemic heart disease. However, the mechanisms responsible for this mobilization are poorly understood. We examined the relationship between plasma levels of bioactive lipids and number of circulating progenitor cells (CPCs) in patients (N = 437) undergoing elective or emergent cardiac catheterization. Plasma levels of sphingosine-1 phosphate (S1P) and ceramide-1 phosphate (C1P) were quantified using mass spectrometry...

BACKGROUND: Studies of kidney disease associated with cardiac catheterization typically rely on billing records rather than laboratory data. We examined the associations between percutaneous coronary interventions, acute kidney injury, and chronic kidney disease progression using comprehensive Veterans Affairs clinical and laboratory databases. METHODS AND RESULTS: Patients undergoing percutaneous coronary interventions between 2005 and 2010 (N=24 405) were identified in the Veterans Affairs Clinical Assessment, Reporting, and Tracking registry and examined for associated acute kidney injury and chronic kidney disease development or progression relative to 24 405 matched population controls...

BACKGROUND: Adult studies demonstrate that echocardiographic measurements of cardiac function using speckle tracking correlate with invasive measurements, but such data in the pediatric population are sparse. Our aim was to compare speckle-derived measures of cardiac function to measurements routinely obtained by cardiac catheterization in children. METHODS: Echocardiograms were performed on the day of cardiac catheterization. Using Tomtec 2D Cardiac Performance Analysis, longitudinal strain (LS), longitudinal strain rate (LSR), early diastolic LSR, and ejection fraction (EF) for the right and left ventricle (RV and LV) were calculated via speckle tracking...

BACKGROUND: Small-scale studies focused mainly on nonischemic cardiomyopathy (NICM) have shown that a subset of left ventricular assist device (LVAD) patients can achieve significant improvement of their native heart function, but the impact of ischemic cardiomyopathy (ICM) has not been specifically investigated. Many patients with acute myocardial infarction are discharged from their index hospitalization without heart failure (HF), only to return much later with overt HF syndrome, mainly caused by chronic remodeling of the noninfarcted region of the myocardium...
