Objective: Self-perceived health status may be helpful in identifying patients at high risk for adverse outcomes. The Euro Heart Survey on Coronary Revascularization (EHS-CR) provided an opportunity to explore whether impaired health status was a predictor of 1-year mortality in patients with coronary artery disease (CAD) undergoing angiographic procedures. Methods: Data from the EHS-CR that included 5619 patients from 31 member countries of the European Society of Cardiology were used. Inclusion criteria for the current study were completion of a self-report measure of health status, the EuroQol Questionnaire (EQ-5D) at discharge and information on 1-year follow-up, resulting in a study population of 3786 patients. Results: The 1-year mortality was 3.2% (n = 120). Survivors reported fewer problems on the five dimensions of the EQ-5D as compared with non-survivors. A broad range of potential confounders were adjusted for, which reached a p

Aims: Revascularization in patients with coronary artery disease changed over the last two decades, favouring the number of patients treated by means of percutaneous coronary interventions (PCI) when compared with coronary artery bypass grafting (CABG). Many randomized controlled trials (RCTs) have been performed to compare these two competing revascularization techniques. Because of the strict enrolment criteria of RCTs in which highly selected patients are recruited, the applicability of the results may be limited in clinical practice. The current study evaluates to what extent patients in clinical practice were similar to those who participated in RCTs comparing PCI with CABG. Methods and results: Clinical characteristics and 1-year outcome of 4713 patients enrolled in the Euro Heart Survey on Coronary Revascularization were compared with 8647 patients who participated in 14 major RCTs, comparing PCI with CABG. In addition, we analysed which proportion of survey patients would have disqualified for trial participation (n = 3033, 64%), aiming at identifying differences between trial-eligible and trial-ineligible survey patients. In general, important differences were observed between trial participants and survey patients. Patients in clinical practice were older, more often had comorbid conditions, single-vessel disease, and left main stem stenosis when compared with trial participants. Almost identical differences were observed between trial-eligible and trial-ineligible survey patients. In clinical practice, PCI was the treatment of choice, even in patients who were trial-ineligible (46% PCI, 26% CABG, 28% medical). PCI remained the preferred treatment option in patients with multi-vessel disease (57% in trial-eligible and 40% in trial-ineligible patients, respectively, P < 0.001); yet, the risk profile of patients treated by PCI was better than that for patients treated either by CABG or by medical therapy. In the RCTs, there was no mortality difference between PCI and CABG. In clinical practice, however, we observed 1-year unadjusted survival benefit for PCI vs. CABG (2.9 vs. 5.4%, P < 0.001). Survival benefit was only observed in trial-ineligible patients (3.3 vs. 6.2%, P < 0.001). Conclusion: Many patients in clinical practice were not represented in RCTs. Moreover, only 36% of these patients were considered eligible for participating in a trial comparing PCI with CABG. We demonstrated that RCTs included younger patients with a better cardiovascular risk profile when compared with patients in everyday clinical practice. This study highlights the disparity between patients in clinical practice and patients in whom the studies that provide the evidence for treatment guidelines are performed. © The European Society of Cardiology 2006.

- Abstract
Restenosis remains a major limitation of coronary angioplasty in spite of major advances in techniques and technology. Recent studies have demonstrated that ionizing radiation may limit the degree of this problem. Gamma radiation has been shown to be effective in reducing in stent restenosis in humans, and beta radiation following encouraging results in animals has been shown to be feasible in humans. The objective of this study was to assess the feasibility of a 5 F non-centered catheter to deliver beta radiation emitting seeds to the lesion site post angioplasty and its effect on restenosis. Following successful angioplasty, patients were randomized to treatment with 12, 14 or 16 Gy at the angioplasty site. This was delivered with a 5 F non-centered catheter. Twelve beta radiation emitting seeds (90Sr/Y) were delivered to an area 3 cm in length to cover the angioplasty site. Angiographic follow-up was performed at 6 months. Baseline and follow-up angiograms were performed by blinded investigators at a core laboratory. This interim report comprises the first 35 patients to complete 6-month angiographic follow-up. There were no major radiation incidents. Four patients had evidence of angiographic restenosis. The MLD (mm) and percent stenosis were 0.77 +/- 0.27/72.5 +/- 8.6 pre angioplasty, 2.08 +/- 0.4/25.7 +/- 9.8 post angioplasty and radiation and 2.05 +/- 0.59/25.7 +/- 19.8 at follow-up respectively. CONCLUSION: Beta radiation can be feasibly and safely delivered post coronary angioplasty with a very encouraging reduction of restenosis.

Objective: To assess clinically and angiographically the feasibility, safety, and effectiveness of vascular brachytherapy (VBT) in saphenous vein bypass grafts (SVG). Patients and methods: 67 of 1098 (6.1%) consecutive patients of the European registry of intraluminal coronary β brachytherapy underwent treatment for 68 SVG lesions by VBT using a Sr/Y
90 source train (BetaCath). Clinical follow up data were obtained for all of them after a mean (SD) of 6.3 (2.4) months and angiographic follow up was performed in 61 patients (91.0%) after 6.9 (2.0) months. Results: 58 (86.6%) patients were men, their mean (SD) age was 66 (10) years, 28 (41.8%) had unstable angina, and 21 (31.3%) had diabetes. Fifty three (77.9%) lesions were in-stent restenosis, 13 (19.1%) de novo lesions, and 2 (3.0%) non-stented restenotic lesions. Mean (SD) reference diameter before the intervention was 4.19 (0.52) mm, mean (SD) lesion length was 23.56 (20.38) mm, and mean (SD) minimum lumen diameter measured 0.73 (0.62) mm. Mean (SD) acute gain was 3.02 (0.88) mm. The prescribed radiation dose was 20.1 (3.2) Gy. Pullback manoeuvres were performed in 17 (25.0%) of cases. Most patients received combined aspirin and thienopyridin treatment for 6 or 12 months after the procedure. Technical success was obtained in 62 (91.2%) treated lesions and in-hospital major adverse cardiac events occurred in 4.5%. At follow up, mean (SD) reference diameter was 4.20 (0.53) mm, minimum lumen diameter 2.94 (1.50) mm, and late loss 0.86 (1.25) mm. The overall major adverse cardiac events rate was 26.7%. Conclusion: VBT of SVG is feasible and safe. At follow up the reintervention rate and cardiac morbidity and mortality seem to be favourable, considering that interventions in SVG usually are associated with the highest risks.

Background: Percutaneous coronary intervention (PCI) of coronary bifurcation lesions remains a subject of debate. Many studies have been published in this setting. They are often small scale and display methodological flaws and other shortcomings such as inaccurate designation of lesions, heterogeneity, and inadequate description of techniques implemented. Methods: The aim is to propose a consensus established by the European Bifurcation Club (EBC), on the definition and classification of bifurcation lesions and treatments implemented with the purpose of allowing comparisons between techniques in various anatomical and clinical settings. Results: A bifurcation lesion is a coronary artery narrowing occurring adjacent to, and/or involving, the origin of a significant side branch. The simple lesion classification proposed by Medina has been adopted. To analyze the outcomes of different techniques by intention to treat, it is necessary to clearly define which vessel is the distal main branch and which is (are) the side branche(s) and give each branch a distinct name. Each segment of the bifurcation has been named following the same pattern as the Medina classification. The classification of the techniques (MADS: Main, Across, Distal, Side) is based on the manner in which the first stent has been implanted. A visual presentation of PCI techniques and devices used should allow the development of a software describing quickly and accurately the procedure performed. Conclusion: The EBC proposes a new classification of bifurcation lesions and their treatments to permit accurate comparisons of well described techniques in homogeneous lesion groups.

- Abstract
Aims: Haemodynamic monitoring using implantable pressure sensors reduces the risk of heart failure (HF) hospitalizations. Patient self-management (PSM) of haemodynamics in HF has the potential to personalize treatment, increase adherence, and reduce the risk of worsening HF, while lowering clinicians' burden., Methods and Results: The VECTOR-HF I and IIa studies are prospective, single-arm, open-label clinical trials assessing safety, usability and performance of left atrial pressure (LAP)-guided HF management using PSM in New York Heart Association class II and III HF patients. Physician-prescribed LAP thresholds trigger patient self-adjustment of diuretics. Primary endpoints include the ability to perform LAP measurements and transmit data to the healthcare provider (HCP) interface and the patient guidance application, and safety outcomes. This is an interim analysis of 13 patients using the PSM approach. Over 12 months, no procedure- or device-related major adverse cardiovascular or neurological events were observed, and there were no failures to obtain measurements from the sensor and transmit the data to the HCP interface and the patient guidance application. Patient adherence was 91.4%. Using PSM, annualized HF hospitalization rate significantly decreased compared to a similar period prior to PSM utilization (0 admissions vs. 0.69 admissions over 11.84 months, p = 0.004). At 6 months, 6-min walk test distance and the Kansas City Cardiomyopathy Questionnaire overall summary score demonstrated significant improvement., Conclusions: Interim findings suggest that PSM using a LAP monitoring system is feasible and safe. PSM is associated with high patient adherence, potentially improving HF patients' functional status, quality of life, and limiting HF hospitalizations., (© 2024 The Author(s).

- Abstract
Aims: In heart failure (HF), implantable haemodynamic monitoring devices have been shown to optimize therapy, anticipating clinical decompensation and preventing hospitalization. Direct left-sided haemodynamic sensors offer theoretical benefits beyond pulmonary artery pressure monitoring systems. We evaluated the safety, usability, and performance of a novel left atrial pressure (LAP) monitoring system in HF patients., Methods and Results: The VECTOR-HF study (NCT03775161) was a first-in-human, prospective, multicentre, single-arm, clinical trial enrolling 30 patients with HF. The device consisted of an interatrial positioned leadless sensor, able to transmit LAP data wirelessly. After 3 months, a right heart catheterization was performed to correlate mean pulmonary capillary wedge pressure (PCWP) with simultaneous mean LAP obtained from the device. Remote LAP measurements were then used to guide patient management. The miniaturized device was successfully implanted in all 30 patients, without acute major adverse cardiac and neurological events (MACNE). At 3 months, freedom from short-term MACNE was 97%. Agreement between sensor-calculated LAP and PCWP was consistent, with a mean difference of -0.22 ± 4.92 mmHg, the correlation coefficient and the Lin's concordance correlation coefficient values were equal to 0.79 (p < 0.0001) and 0.776 (95% confidence interval 0.582-0.886), respectively. Preliminary experience with V-LAP-based HF management was associated with significant improvements in New York Heart Association (NYHA) functional class (32% of patients reached NYHA class II at 6 months, p < 0.005; 60% of patients at 12 months, p < 0.005) and 6-min walk test distance (from 244.59 ± 119.59 m at baseline to 311.78 ± 129.88 m after 6 months, p < 0.05, and 343.95 ± 146.15 m after 12 months, p < 0.05)., Conclusion: The V-LAP™ monitoring system proved to be generally safe and provided a good correlation with invasive PCWP. Initial evidence also suggests possible improvement in HF clinical symptoms., (© 2023 The Authors.

- Abstract
Two high-risk patients were successfully treated with concomitant implantation of a transapical off-pump beating heart semirigid D-shape annuloplasty device combined in 1 case with a transfemoral edge-to-edge device and in another with transapical chordal implantation. The significant anteroposterior diameter reduction offered by the annuloplasty implantation maximized the leaflet coaptation obtained by the prolapse correction performed with the leaflet devices. Combining the transcatheter annuloplasty device and leaflet/chordal repair technologies represents progress toward definitive transcatheter treatment of degenerative mitral valve disease., (Copyright © 2020 The Society of Thoracic Surgeons.

- Abstract
The prevalence of the left circumflex coronary artery (LCx) as the culprit vessel in ST-segment-elevation myocardial infarction (STEMI) is reportedly lowest among that of the 3 main epicardial arteries, and has not been described for non-STEMI (NSTEMI) and stable angina pectoris. We sought to define the distribution of culprit arteries in these clinical presentations and suggest mechanisms for the differences. We reviewed 189 coronary angiograms of patients with STEMI, 203 with NSTEMI, and 548 with stable angina (n=940), and compared distributions of stenotic and culprit coronary arteries (lesions prompting intervention). Obstructive coronary lesions (≥50% narrowing) were more prevalent in the left anterior descending coronary artery (LAD) (36%-38%) and similar in the LCx and right coronary artery (RCA) (27%-29%), regardless of clinical presentation ( P <0.01). In NSTEMI and stable angina, culprit vessels and total obstructive disease had the same distribution. In STEMI, however, a culprit LCx was significantly less prevalent (17%) than was total obstructive disease (27%; P <0.01), or a culprit LAD (47%) or RCA (34%) (both P <0.001). In our computed tomographic angiographic model of coronary longitudinal strain (percentage of shortening), LCx strain was only 1.5% ± 2.4%, versus 9.5% ± 2.9% for LAD strain and 10.1% ± 3.9% for RCA strain. In STEMI, LCx plaques seem less prone to rupturing. Culprit and total disease distributions are similar in NSTEMI and angina, suggesting a different ischemic pathophysiology in these presentations. Lower LCx longitudinal strain might contribute to reduced plaque rupture in STEMI.

- Abstract
Background: Use of transradial intervention (TRI) is becoming more popular, and recent studies suggest an advantage for TRI in high-risk patients presenting with acute coronary syndrome (ACS). The aim of our study was to describe current utilization and outcomes of transradial intervention (TRI) in real-world patients presenting with ACS., Methods: Data were derived from the ACS Israeli Survey (ACSIS 2010), a nationwide prospective survey of patients presenting with ACS over a 2-month period. Follow-up was continued for up to 1 year., Results: Of 1815 ACS patients undergoing coronary angiography, 613 (34%) underwent TRI, which was more likely to be employed among patients with lower-risk characteristics. Patients undergoing TRI had significantly lower 30-day mortality and in-hospital bleeding. On multivariate analysis, the risk of in-hospital major bleeding was reduced by 60% in patients undergoing TRI (P=.04). However, no significant differences in other components of major adverse cardiac events or mortality were demonstrated at 30 days. All-cause mortality at 1 year was significantly lower among patients who underwent TRI. However, after multivariate adjustment, this effect was no longer significant., Conclusions: In our study of real-world patients, better TRI outcomes are related largely to lower baseline risk of patients allocated to this approach, suggesting that TRI may be underutilized in high-risk ACS patients.

- Abstract
Background: One of the most daunting complications of cardiac catheterization is a cerebrovascular event (CVE). We aimed to assess the real-life incidence, etiology, and risk factors of cardiac catheterization-related acute CVEs in a large cohort of patients treated in a single center., Methods and Results: We undertook a retrospective analysis of 43,350 coronary procedures performed on 30,907 procedure days over the period 1992-2011 and compared patient and procedural characteristics of procedures complicated by CVEs with the remaining cohort. CVEs occurred in 47 cases: 43 were ischemic, 3 intracerebral hemorrhages, and 1 undetermined. The overall CVE rate was 0.15%, with percutaneous coronary intervention (PCI) and diagnostic coronary angiography rates 0.23% and 0.09%, respectively. Using a forward stepwise multivariate logistic regression model including patient demographic and procedural characteristics, a total of 5 significant predictors were defined: prior stroke (OR=15.09, 95% CI [8.11 to 28.08], P<0.0001), presence of coronary arterial thrombus (OR=2.79, 95% CI [1.25 to 6.22], P=0.012), age >75 years (OR=3.33, 95% CI [1.79 to 6.19], P<0.0001), triple vessel disease (OR=2.24, 95% CI [1.20 to 4.18], P=0.011), and performance of intervention (OR=2.21, 95% CI [1.12 to 4.33], P=0.021). An additional analysis excluded any temporal change of CVE rates but demonstrated a significant increase of all high-risk patient features., Conclusion: In a single-center, retrospective assessment over nearly 20 years, cardiac catheterization-related CVEs were very rare and nearly exclusively ischemic. The independent predictors for these events were found to be the performance of an intervention and those associated with increased atherosclerotic burden, specifically older age, triple vessel disease, and prior stroke. The presence of intracoronary thrombus appears also to raise the risk of procedure-related CVE.

- Abstract
Background: The recently released Amplatzer Ductal Occluder 2 (ADO2) was designed specifically for use in small children with moderate-sized shunts and larger children with small patent ductus arterioses (PDA). We report our initial experience with this device., Methods: Patients referred with PDA underwent occlusion using the ADO2. This is a fabric-free nitinol wire 3-lobed device. All cases underwent pre-, intra- and post-procedural echocardiography, with follow up at 1 day and one month. Device sizing for device waist diameter and width was based on aortography., Results: Seven patients with a median age of 3 years and 4 months (range 7 months-23 years) and a median weight of 12 kg (range 7-56 kg) underwent successful PDA closure. The median ductal diameter was 1.5 mm (range 0.4-4 mm). Both transpulmonary (6/7) and transaortic approaches (1/7) were used. Recurrent patency at 24 hours with complete occlusion at 1 month was noted in a single case. A specific device-based length assessment applied resulted in shorter than recommended device selection., Conclusion: The ADO2 broadens the spectrum of PDAs that can be simply and safely treated with devices. The flexibility of the articulations, coupled with the alternative deployment techniques, allow for increased ease of treatment in a range of small patients and specific ductal anatomies. An alternative device-specific length measurement of the duct length may result in less retaining disc protrusion. Broader experience is required to further delineate device and patient selection as well as to document its long-term efficacy and safety.

- Abstract
Unlabelled: The absence of antegrade flow in a coronary artery during an intervention is an ominous finding requiring diagnosis of the underlying cause and rapid treatment to limit myocardial necrosis. The Twin-Pass dual access catheter allows for distal coronary contrast injection without loss of wire position. The aim of this analysis was to determine the opacification and flow features of patients with abrupt arrest of antegrade flow to determine the underlying pathology., Methods: Coronary angiograms of patients with abrupt arrest of antegrade flow during an intervention that underwent distal vessel contrast injection with the Twin-Pass catheter were retrospectively analyzed for five features: antegrade flow, retrograde flow, myocardial blush, presence of contrast stasis in the vessel wall and evidence of an intraluminal filling defect. The features were then correlated with the underlying pathological process and treatment., Results: Seven patients underwent distal contrast injections. Four specific pathological processes were identified: presence of a proximal occlusive lesion; no-reflow due to distal vascular bed dysfunction; long dissection of the vessel with the distal wire residing in the true lumen or alternatively in the dissection plane. The patients were treated according to the pathology with stenting, intracoronary adenosine or wire repositioning., Conclusions: Distal vessel contrast injection using the Twin-Pass catheter in the presence of no-reflow is a simple and rapid technique that allows for the definition of four distinct clinical scenarios. This allows for rapid treatment of the underlying pathological process, reducing the period of end-organ ischemia, limiting occasional unnecessary stent deployment and further improving procedural results.

Background: Femoral artery vascular complications are the most common adverse events following cardiac catheterization. Smaller diameter introducer sheaths and catheters are likely to lower the puncture site complication rate but may hinder visualization., Objectives: To evaluate the safety and angiographic quality of 4 French catheters., Methods: The study was designed to simulate real-life operator-based experience. Diagnostic angiography was performed with either 4F or 6F diagnostic catheters; the size of the catheter used in each patient was predetermined by the day of the month. Patients undergoing 4F and 6F diagnostic angiography were ambulated after 4 and 6 hours, respectively. The following technical parameters were recorded by the operator: ease of introducer sheath insertion, ease of coronary intubation, ease of injection, coronary opacification, collateral flow demonstration, and overall assessment. Adverse events were recorded in all patients and included minor bleeding, major bleeding (necessitating blood transfusion), minor hematoma, major hematoma, pseudo-aneurysm formation and arteriovenous fistula., Results: The study group included 177 patients, of whom 91 were in the 4F arm and 86 in the 6F arm. Demographic and procedural data were similar in both groups. Seventy-seven percent of 6F and 50% of 4F procedures were evaluated as excellent (P < 0.05). This difference was attributed to easier intubation of the coronary ostium and contrast material injection, increased opacification of the coronary arteries, and demonstration of collateral flow with 6F catheters. Complications occurred in 22% of patients treated with 6F catheters and in 10% of those treated with 4F catheters (P = 0.11). Of the 50 patients who switched from 4F to 6F 12% had complications. In patients undergoing diagnostic angiography, the complication rate was 10% vs. 27% (most of them minor) in the 4F and 6F groups, respectively (P < 0.05)., Conclusions: Patients catheterized with 4F have fewer complications compared with 6F diagnostic catheters even when ambulated earlier. Although 4F had a reduced quality compared to 6F angiographies, they were evaluated as satisfactory or excellent in quality 85% of the time. 4F catheters have a potential for reduced hospitalization stay and are a good option for primary catheterization in patients not anticipated to undergo coronary intervention.

- Abstract
Balloon angioplasty results in a combination of plaque compression and fracture, creation of intimal flaps and localized medial dissection, as well as the stretching and remodeling of the arterial wall. The application of eccentric pressure to the vessel wall allows for the balloon force to be focused along a specified line resulting in a reduction in vessel resistance with an improved or equivalent result at a lower pressure. The FX miniRAIL is a novel balloon angioplasty catheter that has two external wires that are compressed by the inflating balloon into the vessel wall. It was tested in comparison to conventional balloon injury in a porcine coronary model. At equivalent balloon artery ratios no increase in the length of dissections occurred, but a characteristic longitudinal "cut" was noted in the presence of the FX miniRAIL. A similar finding was demonstrated in sample human cases when interrogated by IVUS and OCT.

- Abstract
Background: Prior studies have suggested that women are at higher risk for morbidity and mortality during coronary angioplasty, although long-term prognosis is similar after successful procedures., Objectives: To examine the role of gender in coronary stenting, including immediate procedural success as well as early and late outcomes., Methods: The study group comprised 560 consecutive patients (119 women and 441 men) who had undergone stenting over a 3 year period., Results: The indications for coronary stenting were similar among women and men, and stents were successfully deployed at similar rates without complications (92 vs. 90% respectively). Cardiac death or myocardial infarction within 30 days of the procedure was observed in 5% of women and men, whereas none of the women, compared to 1.4% of men, had early revascularization. Bleeding complications occurred in 4% of women and 2% of men. During 10 +/- 2.8 months of follow-up, 58% of women and men underwent repeat cardiac catheterization, revealing similar rates of restenosis, 36 vs. 32% respectively. During the study period, 3.3% of women as compared to 0.9% of men had a cardiac death (not significant). Cardiac death or myocardial infarction was observed in 7% of women and 8% of men, and the combined endpoint of death, myocardial infarction or revascularization, was noted in 24% and 26% respectively. Multivariate Cox analyses of the clinical, angiographic and procedural characteristics revealed that multiple stent deployment was the only predictor of major adverse cardiac event among men, whereas none of these characteristics predicted outcome in women., Conclusion: Coronary stenting is performed with similar success rates among women and men, with similar restenosis rates as well as early and late major adverse cardiac events.

- Abstract
The significance of heavily calcified proximal left anterior descending coronary artery stenosis in a 57-year-old man was assessed physiologically using a Doppler flow wire. Intravascular ultrasound guidance allowed for adequate dilatation with a cutting balloon and optimization of stent deployment. The cutting balloon offers an effective alternative in this challenging scenario.

- Abstract
Background: Transmyocardial laser revascularization (TMLR) has potential benefit for patients with end-stage coronary artery disease and intractable angina not amenable to conventional revascularization techniques. Neovascularization has been proposed to occur around the laser channels. Our aim was to determine the feasibility of a novel nonlaser myocardial revascularization technique and its effect on angiogenesis in a nonischemic porcine model., Methods: In the first phase, six transmyocardial stainless steel coil implants (TMI) were deployed to the lateral wall of the left ventricle in each of 6 pigs. The animals were sacrificed at 8 and 12 weeks, with a single animal dying prematurely at 4 weeks, and the myocardium was assessed for new vessel growth. In the second phase, 8 implants were deployed in each of 12 pigs with regular fluoroscopic follow-up until sacrifice at 2 weeks to assess implant stability., Results: The deployment procedure was safe and feasible with no complications evident. A significant increase in new vessels at implant sites with 5.43 +/- 3.67, 4.97 +/- 2.44, and 3.57 +/- 2.29 seen per high power field at 12, 8, and 4 weeks, respectively, compared to 1.00 +/- 1.06 (p < 0.0001) in control myocardium. There was no evidence of implant migration in Phase 2., Conclusions: TMIs can feasibly be deployed in the nonischemic pig model with a high success rate. The presence of angiogenesis at the implant site and the maintenance of this reaction for 3 months implies that TMI may offer an alternative to TMLR while providing a platform for delivery of angiogenic factors.

- Abstract
Background: Postcoronary angioplasty vascular brachytherapy (VBT) has emerged as a successful intervention for restenosis prevention in some clinical scenarios. Longer-term follow-up after VBT in de novo nonstented lesions has not been reported., Methods and Results: Thirty patients treated with post-percutaneous transluminal coronary angioplasty (PTCA) VBT with Sr90 underwent clinical and angiographic follow-up at 6 and 24 months. Specific vessel segment quantitative coronary angiographic analyses were performed to identify radiation edge effects. Nineteen patients who had not undergone index procedure stenting or target vessel revascularization (TVR) over the 2-year period were analyzed separately. Of the 30 patients, 3 underwent TVR by 6-month follow-up. An additional 4 patients required TVR between 6 and 24 months. In the total cohort of 26 patients undergoing angiographic follow-up at 6 and 24 months, an increase in minimal lumen diameter of the initial target segment was noted at 6 months compared with postprocedure analysis (2.31+/-0.48 versus 2.04+/-0.43 mm, P<0.05). At 24 months, this was no longer significant (2.19+/-0.61 mm). In the proximal segments of the entire cohort and the nonintervened subgroup, the principal late loss occurred over the first 6 months with no additional late loss at 2-year follow-up. The distal segments remained stable over the entire follow-up period., Conclusions: Although some late failures of post-PTCA VBT are seen between 6 and 24 months, most treated vessels remain stable with no late loss or additional luminal increase beyond the 6-month period. This suggests that late aneurysm formation and significant late edge restenosis are unlikely in VBT after PTCA of de novo lesions for up to 2 years.

- Abstract
Objectives: The aim of this study was to determine the natural history of postangioplasty intravascular ultrasound (IVUS)-detected dissections and to assess the influence of intracoronary beta-radiation on dissection resolution., Background: Intracoronary radiotherapy is considered to impair exaggerated vessel healing. Conversely, excessive healing impairment may increase the risk of complications due to unhealed dissection. Alternatively, residual dissection may represent an innocent marker of adequate therapy., Methods: Immediate postangioplasty and six-month follow-up IVUS studies of 94 patients in the IVUS substudy of the MultiVitamins and Probucol (MVP) trial and 26 nonstented patients in the Beta Energy Restenosis Trial (BERT) were analyzed for the presence or absence of dissection., Results: Of the 28 patients with postangioplasty dissections in MVP, only one had evidence of residual dissection at six months (95% confidence interval [CI] for failure rate 0.2%; 20.2%). Conversely, 9 of 16 dissections had healed in BERT (95% CI for failure rate 30.6%; 79.2%) (p < 0.0002). Nevertheless, an index based on dissection arc and length demonstrated improvement in the irradiated patients. Irradiated patients with residual dissections showed significant increase in lumen area at six-months (5.10 +/- 0.98 to 7.11 +/- 2.61 mm2, p < 0.02) not noted when there was resolution of the dissection (6.03 +/- 2.38 to 6.36 +/- 3.33 mm2, p = NS). In both groups the external elastic membrane area was unchanged at follow-up., Conclusions: Resolution appears to be the natural history of IVUS-detected dissections in most cases. Significant resolution of dissection occurs following intracoronary beta-radiation as reflected in reduced dissection index at six-months in these patients, although significant impairment of vessel wall healing was noted.

- Abstract
Background: Postangioplasty (PTCA) intracoronary radiation therapy (ICRT) has been demonstrated to limit restenosis. The consequences of these procedures on coronary reactivity are unknown., Methods and Results: Porcine coronary arteries were studied after PTCA immediately (n=5) and 6 weeks (n=5) after ICRT (n=5 and 5, respectively), after combined PTCA+ICRT (n=5 and 7, respectively), and after no intervention (n=11). A 3-cm-long source train of Sr/Y(90) was used in vivo to deliver 16 Gy at a depth of 2 mm from the source center, as used in clinical trials. Arterial rings were mounted on myographs to record isometric tension. After achieving steady-state contraction to depolarizing physiological solution containing 40 mmol/L KCl, measured baseline tension was significantly elevated immediately after all interventions. It returned to normal levels 6 weeks after PTCA and ICRT alone but was significantly reduced if combined. Active contractions induced by 40 mmol/L KCl were maintained after combined therapy both immediately after and at 6 weeks. In these depolarizing conditions, nitric oxide-dependent relaxation to substance P was trivial after PTCA+ICRT and reduced after ICRT, whereas in the presence of physiological solution and N(omega)-nitro-L-arginine, substance P-induced relaxation was reduced after PTCA and abolished after PTCA+ICRT 6 weeks after intervention. In rings without endothelium, the relaxation mediated by sodium nitroprusside (0.1 micromol/L) was reduced immediately after PTCA and at 6 weeks., Conclusions: PTCA+ICRT altered the passive mechanical properties of porcine coronary arterial wall. Furthermore, at 6 weeks, receptor-operated release of endothelium-derived nitric oxide and endothelium-derived hyperpolarizing factor was reduced by ICRT and PTCA alone, respectively, and was prevented by their combination.

- Abstract
Background: Endovascular radiation is emerging as a potential solution for the prevention and treatment of restenosis. Its effects on the morphology of unstented vessels cannot be determined by angiography and therefore require the use of intravascular ultrasound., Methods and Results: Through a 5F noncentered catheter for delivery of a 90Sr/Y source train, 12, 14, or 16 Gy at 2 mm was delivered to native coronary arteries after successful balloon angioplasty in 30 patients. Four patients required stent deployment in the first week. Quantitative coronary angiography and IVUS were performed during the initial procedure and at 6-month follow-up. Binary angiographic restenosis was present in 3 of 30 patients, with target lesion and vessel revascularization performed in 3 and 5 patients, respectively. Angiographic late loss was -0.02+/-0.60 mm, with a -0.09+/-0.46 loss index. IVUS demonstrated no significant reduction in lumen area (from 5.69+/-1.72 mm2 after treatment to 6. 04+/-2.63 mm2 at follow-up), with no significant change in external elastic membrane area (13.71+/-4.54 to 14.22+/-4.71 mm2) over the 6-month follow-up. Wall area was 8.01+/-3.85 mm2 after radiation therapy and 8.19+/-3.44 mm2 at follow-up (P=NS). No significant differences were noted between the different dose groups., Conclusions: beta-Radiation therapy resulted in a low restenosis rate with negligible late loss by angiography. By IVUS, beta-radiation was shown to inhibit neointima formation, with no reduction of total vessel area at 6-month follow-up.
