Abstract
AIMS Non-invasive assessment of stable chest pain patients is a critical determinant of resource utilization and clinical outcomes. Increasingly coronary computed tomography angiography (CCTA) with selective CCTA-derived fractional flow reserve (FFRCT) is being used. The ADVANCE Registry, is a large prospective examination of using a CCTA and FFRCT diagnostic pathway in real-world settings, with the aim of determining the impact of this pathway on decision-making, downstream invasive coronary angiography (ICA), revascularization, and major adverse cardiovascular events (MACE). METHODS AND RESULTS A total of 5083 patients with symptoms concerning for coronary artery disease (CAD) and atherosclerosis on CCTA were enrolled at 38 international sites from 15 July 2015 to 20 October 2017. Demographics, symptom status, CCTA and FFRCT findings, treatment plans, and 90 days outcomes were recorded. The primary endpoint of reclassification between core lab CCTA alone and CCTA plus FFRCT-based management plans occurred in 66.9% [confidence interval (CI): 64.8-67.6] of patients. Non-obstructive coronary disease was significantly lower in ICA patients with FFRCT ≤0.80 (14.4%) compared to patients with FFRCT >0.80 (43.8%, odds ratio 0.19, CI: 0.15-0.25, P < 0.001). In total, 72.3% of subjects undergoing ICA with FFRCT ≤0.80 were revascularized. No death/myocardial infarction (MI) occurred within 90 days in patients with FFRCT >0.80 (n = 1529), whereas 19 (0.6%) MACE [hazard ratio (HR) 19.75, CI: 1.19-326, P = 0.0008] and 14 (0.3%) death/MI (HR 14.68, CI 0.88-246, P = 0.039) occurred in subjects with an FFRCT ≤0.80. CONCLUSIONS In a large international multicentre population, FFRCT modified treatment recommendation in two-thirds of subjects as compared to CCTA alone, was associated with less negative ICA, predicted revascularization, and identified subjects at low risk of adverse events through 90 days.

Two in one is better than one plus one: comparison of adverse events between combining electrophysiological examination and coronary angiography versus performing them consecutively. J Interv Card Electrophysiol 2017; 50:203-209. [PMID: 29177982 DOI: 10.1007/s10840-017-0298-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/05/2017] [Accepted: 11/16/2017] [Indexed: 10/18/2022]
Abstract
PURPOSE In some patients, both an electrophysiological examination (EPS) and a coronary angiography (CA) are necessary. It might be preferable to choose a combined approach of EPS and CA versus performing them consecutively. The purpose of this study is to evaluate the type and rate of adverse events between both approaches. METHODS Patients were eligible if they underwent a CA and an EPS in a combined approach or in a time interval of at most 2 months. In all patients, clinical adverse events were recorded. RESULTS A total of 1184 patients were included. CA and EPS were performed in a combined procedure (comb) in 492 patients, whereas they were performed consecutively in 692 patients (cons). The acute major complication rate was 0.67%, showing no differences between both groups. In the comb 6.9% and in the cons 6.6% of vascular complications were observed (p = 0.20). The rates of AV fistula and hematoma needing transfusion showed a significantly higher rate in the cons group (p = 0.018 and p = 0.045, respectively). In a multivariate logistic regression analysis, age was a significant predictor for groin complications. After propensity matching, AV fistula occurred significantly more often in the cons group (p = 0.002). CONCLUSION Overall, serious adverse events were rare and there were no differences between the combined approach of EPS and CA and the consecutive approach; however, the occurrence of AV fistula and groin hematoma needing transfusion occurred significantly less in the combined procedure group. Therefore, a combined approach is preferable to a consecutive one.

Femoral arterial closure using ProGlide® is more efficacious and cost-effective when ambulating early following cardiac catheterization. IJC HEART & VASCULATURE 2016; 13:6-13. [PMID: 28616553 PMCID: PMC5454184 DOI: 10.1016/j.ijcha.2016.09.002] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2016] [Revised: 09/08/2016] [Accepted: 09/24/2016] [Indexed: 11/30/2022]
Abstract
OBJECTIVE This was a prospective, single-center study evaluating the efficacy and cost-effectiveness of early ambulation (within 30 min) following femoral artery closure with the ProGlide® suture-mediated vascular closure device (PD) in patients undergoing diagnostic cardiac catheterization compared with manual compression. BACKGROUND It is unclear whether early ambulation with ProGlide is safe or is associated with patient satisfaction and cost savings as compared with manual compression (MC). METHODS AND RESULTS Inclusion criteria were met in 170 patients (85 PD and 85 MC patients). Patients ambulated 20 ft. within 30 min (PD) or after the requisite 4 h recumbent time (MC) if feasible. Primary endpoint was time-to-ambulation (TTA) following device closure. We also directly compared the safety of closure, times-to-hemostasis (TTH), -ambulation (TTA) and -discharge (TTD) with MC and, using a fully allocated cost model, performed cost analysis for both strategies. Multivariate analysis was used to determine predictors of patient satisfaction. The primary endpoint of safe, early ambulation was achieved following closure (mean of 27.1 ± 14.9 min; 95% confidence interval [CI] 25.2-30.2). Predictors of patient satisfaction in the PD group were absence of pain during closure, decreased TTA, and drastic reductions in TTD; the latter contributed indirectly to significant cost savings in the PD group (1250.3 ± 146.4 vs. 2248.1 ± 910.2 dollars, respectively; P < 0.001) and incremental cost savings by strategy also favored closure over MC ($84,807). CONCLUSIONS ProGlide is safe and effective for femoral artery closure in patients who ambulate within 30 min after cardiac catheterization; translating into improved patient satisfaction and substantial cost savings.

Abstract
Millions of femoral arterial punctures are performed annually worldwide for the diagnosis and treatment of cardiovascular disease. Traditionally, hemostasis following arterial sheath removal has employed compression techniques but more recently, a number of arteriotomy closure devices have become available, none of which have been shown to produce an outcome superior to the standard technique of compression. The authors investigated a novel device, which utilizes a nitinol clip that gathers the artery from the outside producing a purse-string-like seal, with very promising results. The authors feel that this device has great potential, may impact significantly on the closure of arteriotomy sites and may also find application in other aspects of procedural medicine.

Abstract
Some risk exposures, including many medical and surgical procedures, typically carry hazards of death that are difficult to convey and appreciate in absolute terms. I propose presenting the death risk as a condensed life experience (i.e., the equivalent amount of life T that would carry the same cumulative mortality hazard for a person of the same age and sex based on life tables). For example, if the risk of death during an elective 1-hour procedure is 0.01%, and same-age and same-sex people have a 0.01% death risk over 1 month, one can inform the patient that "this procedure carries the same death risk as living 1 month of normal life." Comparative standards from other risky activities or from a person with the same disease at the same stage and same predictive profile could also be used. A complementary metric that may be useful to consider is the death intensity. The death intensity λ is the hazard function that shows the fold-risk estimate of dying compared with the reference person. The death intensity can vary substantially for different phases of the event, operation, or procedure (e.g., intraoperative, early postoperative, late postoperative), and this variability may also be useful to convey. T will vary depending on the time window for which it is computed. I present examples for calculating T and λ using literature data on accidents, ascent to Mount Everest, and medical and surgical procedures.

Abstract
PURPOSE We evaluated the relationship between internal thoracic artery (ITA) stenosis anastomosed to the left anterior descending artery (LAD) and the degree of LAD stenosis using 320-detector row computed tomography (320-ADCT) and adenosine thallium-201 myocardial perfusion scintigraphy (Tl-201-MPS). METHODS We included 101 patients who underwent coronary artery bypass grafting (CABG) using ITA grafts; 320-ADCT and adenosine Tl-201-MPS were performed 2-3 months after CABG. Clinical parameters, degree of LAD stenosis, and regional myocardial ischemia of the LAD territory were compared between patients without ITA stenosis (Group A) and with ITA stenosis (Group B). RESULTS Thirty patients (30%) had ≤75% LAD stenosis, and 9 patients (30%) showed significant ITA stenosis. Regional ischemia was noted in 23 patients (23%). There were no differences in clinical parameters between the 2 groups. Twenty-two patients (24%) in Group A and 8 patients (89%) in Group B had ≤75% LAD stenosis (P <0.002). No Group B patients had regional myocardial ischemia of the LAD territory. CONCLUSION We concluded that ≤75% LAD stenosis significantly influences ITA stenosis, without associated regional myocardial ischemia of the LAD territory. Non-invasive 320-ADCT and adenosine Tl-201-MPS for ITA evaluation may be useful for long-term follow-up of patients after CABG.

Abstract
OBJECTIVES Coronary computed tomography angiography (CTA) has proven clinically useful for non-invasive assessment of coronary pathology. However, coronary calcium can reduce its diagnostic value. The objective of this study was to define a calcium score above which CTA appears less reliable. DESIGN We prospectively investigated 109 patients referred for elective coronary angiography (CA). With a 64-slice CT-scanner, coronary calcium was determined and expressed in Agatston unit (AU). A significant coronary stenosis was defined as > or =50% luminal diameter reduction. Following blinded interpretation, diagnostic values of CTA at different levels of AU were calculated using quantitative CA as reference. RESULTS A strong association with stent and the severity of coronary calcium was observed. In patients without stents (n = 91) sensitivity, specificity and positive and negative predictive value for presence of significant stenosis were: 100%, 91%, 74%, and 100% in patients with a calcium score < or =400 AU versus 100%, 17%, 75%, and 100% in patients with a score >400 AU. CONCLUSIONS The diagnostic accuracy of CTA in patients with no or little coronary calcium is excellent. However, in patients with an Agatston score >400 specificity declines and therefore, these patients should not go on to CTA, but be referred to CA instead.

Abstract
BACKGROUND There is a paucity of data regarding the impact of retroperitoneal hematoma (RPH) volumes, as detected by computed tomography (CT) scanning, on patient morbidity and mortality. Therefore, we wanted to determine the natural history of RPHs and the effect of size on local and systemic outcomes. METHODS We performed a volumetric analysis of CT-documented RPHs managed at our institution between 1985 and 2006 along with a retrospective chart review. RESULTS We included 81 cases of RPH in this study. The mean Acute Physiology, Age, and Chronic Health Evaluation II (APACHE II) score was 12.8 +/- 0.72 (score +/- SE). By univariate analysis, the size of the hematoma showed a significant correlation with the development of local mass effects, delayed mass effects, 6-month mortality, major morbidity, pulmonary complications, fluid overload, and the requirement for operative evacuation (p < 0.05). Receiver operating characteristic analysis revealed that a size > or = 1600 cm(3) was > 80% sensitive and specific for predicting a delayed mass effect or an increase in 6-month mortality. Multivariate analysis controlling for factors such as APACHE II and packed red blood cells transfused showed that the volume of the RPH was an independent predictor for the development of local mass effects, pulmonary insufficiency, and fluid overload. CONCLUSIONS Large RPHs are clearly associated with worse patient outcomes. Surgical intervention may be warranted for the treatment of RPHs > or = 1600 cm(3).

Abstract
PURPOSE To prospectively evaluate the diagnostic accuracy of 64-section computed tomography (CT) for the assessment of in-stent or peristent restenosis, with conventional coronary angiography as the reference standard. MATERIALS AND METHODS The study was approved by the medical ethics committee, and informed consent was obtained in all 50 enrolled patients (40 men, 10 women; mean age, 60 years +/- 11 [standard deviation]). In addition to conventional coronary angiography with quantitative coronary angiography, 64-section CT was performed. For each stent, assessability was determined and was related to stent characteristics and heart rate by using a chi(2) test. On the interpretable images of stents and peristent lumina (5.00 mm proximal and distal to the stent), the presence of significant (> or =50%) restenosis was determined. For this analysis, partially overlapping stents were considered to represent a single stent. RESULTS Of 76 stents, 65 (86%) were determined to be assessable. Increased heart rate and overlapping positioning were associated with increased uninterpretability of the images of stents (P < .05), whereas location of the stent and thickness of the strut were not. In seven patients, stents were placed in an overlapping manner, resulting in 58 stents available for the evaluation of significant (> or =50%) in-stent restenosis. All six significant (> or =50%) in-stent restenoses were detected, and the absence of significant (> or =50%) restenosis was correctly identified in the 52 remaining stents, resulting in sensitivity and specificity of 100%. Sensitivity and specificity for the detection of significant (> or =50%) peristent stenosis were 100% and 98%, respectively. CONCLUSION In selected patients with previous stent implantation, 64-section CT can be used to evaluate in-stent restenosis with high accuracy. Accordingly, the technique may be useful for noninvasive exclusion of in-stent or peristent restenosis, thereby avoiding invasive imaging in a considerable number of patients.

Abstract
PURPOSE OF REVIEW Although contrast-induced nephropathy (CIN) is common and portends a significant morbidity and mortality, only few large and well designed trials have assessed the available prophylactic measures and there are no clear evidence-based guidelines that can easily be adopted by the clinician. We critically discuss the evidence for periprocedural hydration, pharmacological agents, periprocedural withdrawal of medication, application of renal replacement therapy and the use of contrast media. RECENT FINDINGS Pending confirmation of the superiority of sodium bicarbonate, NaCl 0.9% remains the fluid of choice for periprocedural hydration. A recent trial found a dose-dependent beneficial effect of acetylcysteine on CIN and mortality, adding to the controversy on the prophylactic use of this agent. Publication bias of acetylcysteine trials may have confounded the results of the meta-analyses, since negative results were more likely to be published as an abstract only. Periprocedural haemofiltration protected against CIN in a high-risk population, but the results require confirmation before the technique can be recommended. SUMMARY Pending randomized controlled trials with rigorous scientific design, we propose practical mixed evidence-based and opinion-based guidelines for the prevention of CIN, using a stratification of patients into three risk groups, based on their renal function and a risk-prediction model.

Abstract
PURPOSE To review the literature on the diagnostic performance of multidetector computed tomographic (CT) angiography for assessment of symptomatic coronary artery disease, with conventional coronary angiography as the reference standard. MATERIALS AND METHODS A PubMed and manual search of the literature published between January 1998 and May 2006 on use of multidetector CT angiography compared with coronary angiography in patients with symptomatic coronary artery disease was performed. Summary estimates of diagnostic odds ratio, sensitivity, and specificity were calculated. Random-effects models were used to compare the diagnostic performance of four-, 16-, and 64-detector CT angiographic units, and the proportion of nonassessable coronary arterial segments was evaluated. RESULTS Fifty-four studies were included in the meta-analysis: 22 studies with four-detector CT angiography, 26 with 16-detector CT angiography, and six with 64-detector CT angiography. The pooled sensitivity and specificity for detecting a greater than 50% stenosis per segment were 0.93 (95% confidence interval [CI]: 0.88, 0.97) and 0.96 (95% CI: 0.96, 0.97) for 64-detector CT angiography, 0.83 (95% CI: 0.76, 0.90) and 0.96 (95% CI: 0.95, 0.97) for 16-detector CT angiography, and 0.84 (95% CI: 0.81, 0.88) and 0.93 (95% CI: 0.91, 0.95) for four-detector CT angiography, respectively. Results of regression analysis indicated that the diagnostic performance significantly improved with the newer generations of multidetector CT scanners (64- and 16-detector vs four-detector units), adjusted for exclusion of nonassessable segments, and contrast agent concentration used (P < .05). Simultaneously, the nonassessable proportion of segments significantly decreased with the newer generations of multidetector CT scanners, adjusted for heart rate, prevalence of significant disease, and mean age. CONCLUSION With the newer generations of multidetector CT scanners, the diagnostic performance for the assessment of coronary artery disease has significantly improved, and the proportion of nonassessable segments has decreased.

Abstract
BACKGROUND Magnetic resonance imaging (MRI) and multislice computed tomography (MSCT) have emerged as potential noninvasive coronary imaging techniques. The objective of the present study was to clarify the current accuracy of both modalities in the detection of significant coronary artery lesions (compared to conventional angiography as the gold standard) by means of a comprehensive meta-analysis of the presently available literature. METHODS A total of 51 studies on the detection of significant coronary artery stenoses (> or = 50% diameter stenosis) and comparing results with conventional angiography were identified by means of a MEDLINE search. Weighted sensitivities, specificities, and predictive values, all with 95% CIs, as well as summary odds ratios, were calculated for both techniques. In addition, the relationship between diagnostic specificity and disease prevalence was determined using metaregression analysis. RESULTS A comparison of sensitivities and specificities revealed significantly higher values for MSCT (weighted average 85% [95% CI 86%-88%] and 95% [95% CI 95%]) as compared with MRI (weighted average 72%, 95% CI 69%-75% and 87%, 95% CI 86%-88%). A significantly higher odds ratio (16.9-fold) for the presence of significant stenosis was observed for MSCT as compared with MRI (6.4-fold) (P < .0001). Linear regression analysis revealed a better specificity for MSCT versus MRI in lower disease prevalence populations (P = .056). CONCLUSION Meta-analysis of the available studies with MRI and MSCT for noninvasive coronary angiography indicates that MSCT has currently a significantly higher accuracy to detect or exclude significant coronary artery disease.

Abstract
OBJECTIVES To estimate the frequency and nature of complications in patients undergoing diagnostic cardiac catheterisation and to assess time trends in complications since the introduction of a voluntary cooperative audit. METHODS Cardiac centres undertaking diagnostic cardiac catheterisation in England and Wales during the 10 years 1990-9 were invited to join the study. Each participating centre reported numbers of patients catheterised each month and details of complications and deaths as they occurred. Complication rates were calculated for the main diagnostic procedures and for each participating hospital and time trends in complications were examined. RESULTS 41 cardiac centres contributed. 211 645 diagnostic procedures in adults and 7582 paediatric procedures were registered. The majority (87%) of diagnostic catheter studies in adults were left heart studies with coronary arteriography. The overall complication rate for adult procedures was 7.4/1000, with mortality at 0.7/1000; for paediatric procedures the complication rate was similar but mortality rather higher. Complication rates varied between centres but there was little association with caseload. Time trends across the decade showed both complication and mortality decreasing; from 9.5 to 5.8/1000 and from 1.4 to 0.4/1000, respectively. CONCLUSION Complication rates of diagnostic catheterisation are low but neither negligible nor irreducible. While voluntary audit of cardiac catheter complications is useful and inexpensive, there is a clear need to establish a formal reporting system in all cardiac catheter laboratories, with clear definitions of reportable complications.

Abstract
UNLABELLED Multislice computed tomography (MSCT) is a non-invasive and validated technique to detect coronary stenoses. Some questions remain about its accuracy to detect coronary stenoses (CS), especially for asymptomatic patients (P) when a prior stress test isn't conclusive. METHODS MSCT was performed among 45 asymptomatic men (mean age: 58,3 +/- 16), with a high ten year risk of fatal cardiovascular disease (SCORE 2003 data for low-risk regions of Europe), without any previous coronary history and with previous non conclusive exercise testing. When significant (> 50%) CS was suspected at MSCT, an angiocoronarography (AC) was done. RESULTS Eighteen MSCT were normal, unsignificant CS (< 50%) were detected on 14 MSCT and significant coronary stenoses (SCS) for 13 P. Among this 13 P, 19 SCS were identified: 2 SCS of left main coronary artery (CA), 9 of the left descending CA, 6 of the right CA and 2 of the left circumflex CA. 13 CS were confirmed at AC. Finally, because of critical angiographic lesions +/- ischemia at nuclear tomoscintigraphy (NT), 9 P had coronary revascularization (7 catheter based, 2 surgical bypass), 4 P had medical treatment. DISCUSSION Benefits of this preliminary study are obvious: 9 coronary revascularization/45 P. However, the place of MSCT for the screening of CS is uncertain, but may be usefull as a complement for the screening of coronary arterial disease.

Abstract
Our objective was to evaluate the safety of percutaneous transfemoral catheterization performed by way of synthetic aortofemoral vascular grafts. Between 1994 and 2003, 123 catheterization procedures were performed using a synthetic aortofemoral graft (median graft age 2.5 years, range 4 days to 10.3 years), including 63 (51%) interventional and 60 (49%) diagnostic procedures. Adverse events related to vascular access occurred in 7 of 123 procedures (5.7%), including blood transfusion (4.1%), thrombotic occlusion (1.6%), transient limb ischemia (0.8%), and retroperitoneal hemorrhage (0.8%). No deaths, graft infections, or pseudoaneurysms occurred.

Abstract
Ideally, information on coronary artery stenosis and left ventricular (LV) function is obtained in patients who have unstable angina to allow optimal risk stratification. The value of multidetector-row computed tomography (MDCT) was evaluated for a simultaneous assessment of coronary artery disease and global/regional LV function using a single acquisition. Twenty-five patients who had unstable angina underwent a single multidetector-row computed tomographic acquisition using a 4-slice multidetector-row computed tomographic system. Based on retrospective electrocardiographic gating, images and cine movies were reconstructed, which allowed 2 independent observers to analyze the 9 major coronary artery segments and global/regional LV function. Conventional angiography (with quantitative analysis) and echocardiography served as standards of reference, which were performed </=2 +/- 2.7 days and </=3 hours, respectively, after multidetector-row computed tomographic investigations. Sensitivity, specificity, positive and negative predictive values, and correlations were calculated. Of 225 coronary artery segments, 182 (81%) were assessable by MDCT. Significant (>/=50%) coronary artery stenosis was detected with sensitivities, specificities, and positive and negative predictive values of 95%, 91%, 85%, and 97% for observer 1 and 89%, 87%, 79%, and 94% for observer 2, respectively; the interobserver kappa value was 0.73. MDCT showed excellent agreement with echocardiography for regional wall motion (90%; kappa = 0.88) and LV ejection fraction (correlation 0.95%, mean difference 0.7 +/- 3.9). Thus, MDCT can simultaneously assess coronary artery disease and LV function in patients who have unstable angina. High accuracies in excluding significant coronary artery disease and in confirming normal LV function were observed, suggesting potential clinical use for screening of patients who present with symptoms of unstable angina.

Abstract
The aim of the study was to determine the safety and efficacy of a novel femoral artery closure device (StarClose, Abbott Vascular Devices, Redwood City, CA) following percutaneous coronary intervention employing aspirin, heparin, and glycoprotein (GP) IIb/IIIa inhibition. A prospective nonrandomized single-center pilot study of the StarClose device included a subset of patients undergoing percutaneous coronary intervention utilizing GP IIb/IIIa inhibitors. Those that fulfilled the inclusion criteria (age < 80, no periprocedural haematoma, puncture above the superficial femoral and profunda femoralis artery bifurcation, no significant femoral artery disease) underwent closure of the femoral artery puncture site with a StarClose device immediately on completion of the procedure. Time to hemostasis (TTH), bleeding, mobilization, and short-term clinical follow-up data were collected, and an ultrasound scan of the femoral artery was performed 2 weeks later. Twenty-five patients were recruited, of whom 23 underwent percutaneous coronary intervention (PCI). Their mean age was 58 +/- 12 years, 84% were male, and 63% had unstable angina. All were on aspirin 100-150 mg daily and all PCI patients received i.v. heparin 4-10,000 units at commencement of the procedure and clopidogrel 600 mg on completion. Two patients were on a tirofiban infusion and 23 received a double bolus of eptifibatide, each 0.18 mg/kg, separated by 10 min. The procedural success was 100% and device success 23/25 (92%), with 1 failure due to technical error. The median device delivery time was 36 sec (range, 11-178) and median TTH 37 sec (range, 10-509 sec). There were no major adverse events. In 10 patients, a moderate amount of tract ooze required a short period of adjunctive manual compression. Follow-up ultrasound femoral artery scans revealed no compromise of the vessel lumen. Femoral artery closure with the device following coronary angiography and intervention using glycoprotein IIb/IIIa receptor inhibitors is safe and effective. A randomized trial of a larger number of patients is warranted.

Abstract
PURPOSE Mortality due to coronary disease has declined, but the incidence of myocardial infarction has changed little. Whether the incidence of myocardial infarction reflects that of overall coronary disease is unknown. This study was designed to determine whether the incidence of coronary disease has declined over time. METHODS We ascertained incident cases of overt coronary disease (myocardial infarction, sudden death, angiographically diagnosed coronary disease, unstable angina not identified under other rubrics) between 1979 and 1998, using medical records of patients in Olmsted County, Minnesota. Secular trends were analyzed with Poisson regression. RESULTS Between 1979 and 1998, there were 5772 incident cases of coronary disease (myocardial infarction: 1991; sudden death: 1056; angiographically diagnosed coronary disease: 2514; unstable angina: 211). The age- and sex-adjusted incidence of myocardial infarction declined 6% during these two decades and 3% in the second decade, whereas the incidence of myocardial infarction and sudden death combined declined 17% in the first two decades and 9% in the second decade. Use of angiography increased and served as a measure of coronary disease incidence in the second decade. During the second decade, trends in the incidence of all coronary diseases paralleled those of myocardial infarction and of myocardial infarction and sudden death combined, declining 9% (P = 0.06). Cases of coronary disease diagnosed angiographically increased during the period studied. CONCLUSION The trends that we observed suggest that myocardial infarction and sudden death constitute suitable indicators of trends in coronary disease. The decline in incident coronary disease cases supports the hypothesis that the decline in mortality is explained in part by primary prevention and secondary prevention partially mediated by earlier detection.

Abstract
OBJECTIVES The purpose of this study was to assess the value of cardiovascular magnetic resonance (CMR)-determined graft flow and flow reserve in differentiating significant from non-significant vein graft disease. BACKGROUND In patients after coronary artery bypass grafting (CABG), non-invasive testing may be helpful in the detection of recurrent graft disease. METHODS Randomly selected patients (n = 21) scheduled for X-ray angiography because of recurrent chest complaints after CABG were included for evaluation of vein grafts (n = 40) by CMR. Three-dimensional contrast-enhanced CMR angiography was performed and followed by flow measurements at rest and during hyperemia in patent grafts only. Flow reserve was calculated when resting flow exceeded 20 ml/min. Analysis was based on four categories defined by X-ray angiography: occluded grafts (n = 3), grafts with stenosis >50% (n = 19), grafts with stenosis <50% with diseased graft run-off (n = 8), and grafts with stenosis <50% and normal run-off (n = 10). RESULTS The CMR angiography demonstrated occlusion of three grafts. In nine of the 37 patent grafts, basal blood flow was <20 ml/min, all demonstrating significant stenosis at X-ray angiography. In grafts with resting flow >20 ml/min (n = 28), flow reserve significantly differed between grafts without stenosis and grafts with significant stenosis or with diseased run-off (2.5 +/- 0.7 vs. 1.8 +/- 0.9, p = 0.04). An algorithm combining basal volume flow <20 ml/min and graft flow reserve <2 had a sensitivity and specificity of 78% and 80% respectively for detecting grafts with significant stenosis or diseased run-off. CONCLUSIONS This feasibility study showed that quantification of flow and flow reserve by CMR may serve as a non-invasive adjunct to differentiate between vein grafts without stenosis and grafts with significant stenosis or diseased run-off.

Abstract
BACKGROUND Recent findings imply prognostic significance of intracoronary acetylcholine infusion for endothelial function testing. We evaluated whether routine use of this test in coronary angiography patients is safe. METHODS Patients undergoing a first diagnostic coronary angiography were selected to receive intracoronary acetylcholine for endothelial function evaluation. The relation between adverse reactions during infusion and risk factors was analyzed with a logistic regression model. Included in the multiple logistic regression model were the variables with a univariate P value < 0.20. RESULTS Adverse reactions occurred in 16% (49/299) of the patients. This included two life-threatening events caused by occlusive spasm and flow limitation in the left coronary artery. Other adverse events were chest pain (n = 38), AV block or sinus bradycardia (n = 10), dyspnea (n = 3). Adverse reactions were more likely to occur in patients younger than 60 years of age (relative risk, 5.6 [2.2-14.3]). CONCLUSION Intracoronary acetylcholine infusion is safe, but may lead to serious adverse reactions. Care should be taken especially in patients younger than 60 years of age. Routine use of acetylcholine infusion can thus only be justified if it has important prognostic significance. This has to be proven further in large prospective studies.

Abstract
In 1988, the American College of Cardiology/American Heart Association (ACC/AHA) Task Force on Assessment of Diagnostic and Therapeutic Cardiovascular Procedures presented a classification of coronary lesions utilizing 26 lesion features to predict the success and complications of balloon angioplasty. Using data from the Registry of the Society for Cardiac Angiography and Interventions (SCAI) we evaluated the ability of this classification to predict success and complications. Lesion success, death in hospital, emergency cardiac bypass surgery, and major adverse events were evaluated in 41,071 patients who underwent single-vessel angioplasty from January 1993 to June 1996. Logistic models using the ACC/AHA lesion classification, vessel patency, or both, were compared. A new classification based on the interaction of the ACC/AHA classification plus lesion patency was compared with the existing ACC/AHA classification. Vessel patency, added to the ACC/AHA classification, improved prediction of lesion success (p </=0.0001). Class A and patent B lesions had similar success and complication rates, so a simplified classification (SCAI) using only 7 lesion characteristics could be created. This system (I: non-C patent, II: C patent, III: non-C occluded, and IV: C occluded) improved prediction of lesion success compared with the ACC/AHA classification (Bayesian Information Criterion statistic: ACC/AHA 16539, SCAI 15956; and area under the receiver- operating characteristics curve 0.659, 0.693, respectively). The SCAI classification was preferred for predicting major complications and in-hospital death and was similar to the ACC/AHA classification for predicting emergency bypass surgery.

Abstract
This report of the Registry for the Society for Cardiac Angiography and Interventions provides data on the trends in coronary interventional procedures from the time period June 1966 through December 1998. A total of 19,510 consecutive coronary interventional procedures were recorded. Over this time period, significant trends in coronary stent implantation were recorded along with a decreasing reliance on balloon angioplasty as sole therapy. Patients with acute myocardial infarction comprised an increased fraction of all procedures. Almost half of all interventions were performed in patients with multivessel disease. Finally, decreasing rates of in-hospital death and emergent bypass surgery compared to prior reports from the registry characterize the current practice of interventional cardiology. Cathet.

Abstract
Magnetic resonance (MR) angiography and flow mapping have the potential to become a major noninvasive diagnostic tool for the assessment of coronary artery bypass graft morphology and function. Several MR sequences, such as conventional non-respiratory compensated methods, and phase contrast cine flow sequences have been reported for the evaluation of bypass graft patency. However the visualization of different graft segments and the detection of graft stenosis remains difficult. Recent advances in MR coronary angiography and flow mapping are volume coronary angiongraphy with targeted scans, navigator gated angiography, contrast-enhanced angiography, and breath-hold or navigator gated flow sequences. Future approaches, such as navigator gated fast MR techniques resulting in high-resolution angiography in combination with breath-hold MR flow mapping with high temporal resolution, might allow a comprehensive evaluation of bypass graft stenosis and function. This review article will address the major issues concerning the MR evaluation of bypass grafts.

Abstract
OBJECTIVES The purpose of this study was to determine risk factors for adverse events following protamine administration after cardiopulmonary bypass. BACKGROUND Intravenous protamine administration is associated with a risk of severe systemic reactions. However, risk factors for these events have not been well delineated, thus hampering development of preventive strategies. METHODS A case-control study nested within a cohort of consecutive patients undergoing surgery requiring cardiopulmonary bypass was performed. The primary case definition included those events (pulmonary hypertensive and systemic hypotensive) occurring within 10 min of protamine administration in the absence of other measurable causes of hemodynamic compromise. RESULTS Comparing the 53 cases to the 223 control subjects, three risk factors were independently associated with events (multivariable odds ratio [95% confidence interval]): neutral protamine Hagedorn insulin use (8.18 [2.08, 32.2]); fish allergy (24.5 [1.24, 482.3]), and a history of nonprotamine medication allergy (2.97 [1.25, 7.07]). These risk factors demonstrated an increasingly strong association with progressively more specific case definitions. An estimated 39% of cardiopulmonary bypass patients had one or more of these risk factors. Prior intravenous protamine, central venous pressure prior to protamine, preoperative ejection fraction and the need for inotropes when coming off bypass did not exhibit statistically significant associations with events (all p > 0.15). Prior protamine allergy was associated specifically with an increased risk of pulmonary hypertension (multivariable odds ratio 189; 95% confidence interval 13, 2,856). CONCLUSIONS Immunologic factors are important in predisposing individuals to protamine reactions, and a substantial proportion of patients are at considerably increased risk Strategies to reduce the risk of protamine-associated events are needed.

Abstract
PURPOSE Experts recommend left heart catheterization alone to evaluate uncomplicated ischemic heart disease, reserving right heart catheterization for specific indications. Yet some centers routinely perform combined cardiac catheterization (left heart catheterization and right heart catheterization together). SUBJECTS AND METHODS Using 1992-1993 Pennsylvania Medicare claims for cardiac catheterizations (n = 41,180), we examined rates of combined cardiac catheterization for patients with uncomplicated ischemic heart disease for each hospital (n = 73) that performed catheterizations. We compared combined cardiac catheterization rates among hospitals and developed a multivariable model to identify hospital characteristics associated with high combined cardiac catheterization rates. A random sample of cases from the 10 hospitals with the highest combined cardiac catheterization rates were reviewed to determine justification, complications, and results of combined cardiac catheterization. RESULTS Of the 41,180 cardiac catheterizations, 14,177 (34%) were combined procedures. Among hospitals, combined cardiac catheterization rates varied from 2% to 98%. Hospital characteristics associated with high combined cardiac catheterization rates included having a cardiology fellowship program (relative risk [RR] 1.7, 95% confidence interval [CI] 1.1-2.7), location in eastern Pennsylvania (RR 2.5, 95% CI: 1.8-3.5), and volume of catheterizations performed (RR 0.95, 95% CI: 0.91-0.99/100 procedures). For reviewed cases, the most common justification for combined cardiac catheterization was planned revascularization (44%), which is not a specific indication. Only 49% of cases had at least one specific indication for right heart catheterization (range by hospital, 30%-74%). The abnormal findings on the right heart catheterization rarely appeared to change management. CONCLUSION There is wide variation in the practice of combined cardiac catheterization, which appears to be related to teaching status and geographic location. The most common justification for the procedure was planned revascularization, which is not one of the specific indications supported by current literature.

Abstract
The number and types of procedures being performed in the adult cardiac catheterization suite have increased dramatically, with an aggressive move towards percutaneous interventional cardiac procedures. Here we review many of these procedures, including the current trends in North America and Europe. Coronary angioplasty is now more commonly performed than coronary artery bypass grafting. The past 5 years have seen a proliferation of coronary stenting procedures. Restenosis of coronary arteries continues to be a major area of research and concern.

Abstract
The German Society for Cardiac Angiography and Interventions in Private Practice has started a registry of cardiac procedures since 1996 in order to establish a standard for performance. Although quality management for the cath lab makes sense and is also legally required, there is no generally recommended infrastructure for quality assurance existing in Germany at this time. Therefore, the German Society of Cardiologists in Private Practice (BNK) initiated a project in 1994 to develop a computer program for paperless documentation of diagnostic cardiac catheterizations and coronary interventions (PTCA) using a minimal data set. In 1996, 8 private associated groups participated in this project. The (anonymous) analysis of 10,316 diagnostic cardiac catheterizations and 2597 PTCA yielded the following results: In 95% of the patients, diagnostic cardiac catheterization was performed using the femoral and in 5% the brachial/radial approach. The mean volume of administered contrast medium was 164 +/- 138 ml/patient. The mean LV-EF was greater than 50% in 58.4% of the patients and between 30% and 50% in 10.1%. Coronary artery disease was diagnosed in 69.6% of the patients and valvular/congenital heart disease in 8.5%. In 18.4% of the patients undergoing diagnostic cardiac catheterizations no significant heart disease was identified. Mortality in the cath lab as well as the rate of cerebral insults was 0.05%. In 22.9% and 19% of the patients PTCA and cardiac surgery respectively was recommended. In patients undergoing PTCA, stable angina was present in 74.4% and unstable angina in 13.1%. Of the total number of PTCA procedures, 5.8% were performed in the setting of acute myocardial infarction. The PTCA lesion success rate was 96%, the mean diameter stenosis was 81% pre and 6% post-intervention. The mortality rate at 1 month post-PTCA was 0.4%, and myocardial infarction 1.0%. An acute occlusion occurred in 1.3% of the PTCA patients; 0.6% had to be transferred for emergency bypass surgery. None of the cath labs had on-site surgery. In comparison to other registries, our data show some similarities but also some different trends. Thus, our newly developed software proved to be reliable, fast and easy to use. Participating centers receive immediate feedback regarding their position within the whole group.

Abstract
Despite the continuous reduction of sheath sizes in diagnostic and interventional cardiac catheterizations and the discontinuation of coumadin use after coronary stent implantation, a challenging role remains for hemostatic devices in the sealing femoral puncture sites. Since the introduction of the vascular hemostatic device (VHD) in 1991 and the hemostatic puncture closing device (HPCD) in 1992, numerous studies investigating these devices have been published. The deployment success rates reported in 2,292 patients for VHD is 97%, ranging from 88 to 100%. For HPCD, the mean deployment success rate resulting from 622 published patients leads to an identical result of 97%, ranging between 91 and 100%. For time to hemostasis, data have been analyzed according to the four different clinical situations, depending on level of anticoagulation (none or full) and the time of sheath removal (immediate or delayed). In randomized studies, when compared with the manual control groups, both devices revealed a statistically significant reduction in time to hemostasis: 12 to 16 minutes less for diagnostic catheterization and 14 to 30 minutes less for PTCA. As for minor local complications, no clinically relevant differences seem to exist. None of these devices has been proven to reduce major local complications. Prospective trials addressing early mobilization after percutaneous transluminal coronary angioplasty and the cost effectiveness of arterial closure devices in defined subgroups are warranted.

Abstract
Sheath pulling immediately after percutaneous transluminal coronary angioplasty (PTCA) increases patients' comfort, decreases burden for the medical staff, and may reduce hospital costs by shortening the length of stay. Immediate sheath pulling in anticoagulated patients with a low risk of bleeding complications is feasible using hemostatic devices. For the hemostatic puncture closing device (HPCD), published data regarding sheath pulling in patients immediately after PTCA is limited. Furthermore, no study addressed the question whether the recommended deployment time (DT) of 30 min can be reduced to a few minutes. We, therefore, performed a prospective study, randomizing 140 patients to a DT of 5 and 30 min, respectively. There were no statistical differences in gender, age, height, weight, or cardiovascular risk factors between the two groups. Blood pressures measured invasively immediately before sheath removal were comparable. Activated coagulation time just prior to sheath removal was 227 +/- 52 sec in the DT-5 group and 223 +/- 37 sec in the DT-30 group. After deployment, 74% of the DT-5 patients and 71% of the DT-30 patients showed immediate and complete hemostasis. The remaining patients showed only little oozing with complete hemostasis at the time of the final device removal. Hematoma size after 24 hr was 6.2 +/- 4.4 cm2 for DT-5 and 6.8 +/- 8.2 cm2 for DT-30 patients. There was no statistical difference between both groups. No severe bleeding or major complications were observed in either group. Thus, the use of a collagen system with an intra-arterial anchor (HPCD) is effective and safe when sheaths are pulled immediately after PTCA. The reduction of deployment time from 30 to 5 min is not related to an increased risk of bleeding or other vascular complications; patients can be transferred much faster to the ward, therefore reducing the burden on the personnel in the catheterization laboratory and increasing patients' comfort by allowing them to return to their rooms without a sheath.
