RESUMEN
BACKGROUND: Transcatheter aortic valve implantation (TAVI) has become the standard treatment for severe aortic valve stenosis in patients at increased surgical risk. Percutaneous transfemoral (TF) is the access of choice due to its reduced invasiveness and perioperative morbidity/mortality compared with the trans-axillary, aortic, and apical routes. On the other hand, vascular access complications (VACs) of the TF access are associated with prolonged hospitalization, 30-day, and 1-year mortality. In addition, the concomitance of peripheral arterial disease may require associated endovascular management. A multidisciplinary team with Interventional Cardiologists and Vascular Surgeons may minimize the rate of VACs in patients with challenging femoral-iliac access or concomitant disease of other vascular districts, thus optimizing the outcome of TF-TAVI. The aim of this study was to evaluate the role of Vascular Surgeons in TF TAVI procedures. METHODS: We conducted a retrospective single-center review of all TF-TAVI procedures assisted by Vascular Surgeons between January 2016 and December 2020 in a high-volume tertiary hospital. Pre, intra, and postoperative data were analyzed by a dedicated group of Interventional Cardiologists and Vascular Surgeons. VACs were defined according with the Valve Academic Research Consortium (VARC) three guidelines. The outcomes of TF-TAVI procedures with Vascular Surgeons involvement were assessed as study's endpoints. RESULTS: Overall, 937 TAVI procedures were performed with a TF approach ranging between 78% (2016) and 98% (2020). Vascular Surgeons were involved in 67 (7%) procedures with the following indications: concomitant abdominal aortic aneurysm (EVAR + TAVI) - 3 (4%), carotid stenosis (TAVI + CAS) - 2 (3%), hostile femoral/iliac access, or VACs - 62 (93%). Balloon angioplasty of iliac artery pre-TAVI implantation was performed in 51 cases (conventional PTA: 38/51%-75%; conventional PTA + intravascular lithotripsy: 13/51%-25%; stenting: 5/51%-10%). TAVI procedure was successfully completed by percutaneous TF approach in all 62 cases with challenging femoral/iliac access. VACs necessitating interventions were 18/937 (2%) cases, localized to the common femoral or common/external iliac artery in 15/18 (83%) and 3/18 (17%) cases, respectively. They were managed by surgical or endovascular maneuvers in 3/18 (17%) and 15/18 (83%) cases, respectively. Fifteen/18 (83%) VACs were treated during the index procedure. There was no procedure-related mortality or 30-day readmission. CONCLUSION: In our experience, Vascular Surgeon assistance in TAVI procedures was not infrequent and allowed safe and effective device introduction through challenging TF access. Similarly, the concomitant significant disease of other vascular districts could be safely addressed, potentially reducing postoperative related mortality and morbidity. The implementation of multidisciplinary team with interventional cardiologists and vascular surgeons should be encouraged whenever possible.
RESUMEN
BACKGROUND: Drug-coated balloons (DCBs) have shown comparable results with drug-eluting stents in small vessel disease (SVD) percutaneous coronary intervention (PCI) in terms of target vessel revascularization and a reduced incidence of myocardial infarction. However, the relatively high rate of bail-out stenting (BOS) still represents a major drawback of DCB PCI. AIMS: The aim of the study was to investigate the clinical, anatomic, and procedural features predictive of BOS after DCB PCI in SVD. METHODS: We included all consecutive patients undergoing PCI at our institution between January 2020 and May 2022 who were treated with DCB PCI of a de novo lesion in a coronary vessel with a reference vessel diameter (RVD) between 2.0 and 2.5 mm. Angiographic success was defined as a residual stenosis <30% without flow-limiting dissection. Patients who did not meet these criteria underwent BOS. RESULTS: A total of 168 consecutive patients and 216 coronary stenoses were included. The rate of bail-out stent was 13.9%. On multivariate analysis, DCB/RVD ratio (odds ratio [OR]: 4.39, 95% confidence interval [CI]: 1.71-11.29, p < 0.01), vessel tortuosity (OR: 7.00, 95% CI: 1.66-29.62, p < 0.01), distal vessel disease (OR: 5.66, 95% CI: 2.02-15.83, p < 0.01), and high complexity (Grade C of ACC/AHA classification) coronary stenoses (OR: 6.31, 95% CI: 1.53-26.04, p = 0.01) were independent predictors of BOS. CONCLUSIONS: BOS is not an infrequent occurrence in DCB PCI of small vessels and is correlated with vessel tortuosity, distal diffuse vessel disease, higher lesion complexity, and balloon diameter oversizing.

V-A ECMO during bilateral lung transplantation is routinely used when extracorporeal support is needed, in particular in case of patients affected by pulmonary hypertension. We report the case of a patient successfully transplanted with V-A ECMO assistance using a percutaneous double lumen cannula as venous drainage (Protek Duo, CardiacAssist Inc., Pittsburgh, PA) and central aortic cannulation. The double lumen cannula allowed an optimal drainage of the venous system and effective emptying of right heart chambers.

BACKGROUND: Hyperglycemia has been associated with increased inflammatory indexes and larger infarct sizes in patients with obstructive acute myocardial infarction (obs-AMI). In contrast, no studies have explored these correlations in non-obstructive acute myocardial infarction (MINOCA). We investigated the relationship between hyperglycemia, inflammation and infarct size in a cohort of AMI patients that included MINOCA. METHODS: Patients with AMI undergoing coronary angiography between 2016 and 2020 were enrolled. The following inflammatory markers were evaluated: C-reactive protein, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and neutrophil-to-platelet ratio (NPR). Myocardial infarct size was measured by peak high sensitivity troponin I (Hs-TnI) levels, left-ventricular-end-diastolic-volume (LVEDV) and left ventricular ejection fraction (LVEF). RESULTS: The final study population consisted of 2450 patients with obs-AMI and 239 with MINOCA. Hyperglycemia was more prevalent among obs-AMI cases. In all hyperglycemic patients-obs-AMI and MINOCA-NLR, NPR, and LPR were markedly altered. Hyperglycemic obs-AMI subjects exhibited a higher Hs-TnI (p < 0.001), a larger LVEDV (p = 0.003) and a lower LVEF (p < 0.001) compared to normoglycemic ones. Conversely, MINOCA patients showed a trivial myocardial damage, irrespective of admission glucose levels. CONCLUSIONS: Our data confirm the association of hyperglycemic obs-AMI with elevated inflammatory markers and larger infarct sizes. MINOCA patients exhibited modest myocardial damage, regardless of admission glucose levels.

OBJECTIVES: To evaluate the long-term impact of coronary artery disease (CAD) and heart team-guided incomplete coronary revascularization in patients undergoing transcatheter aortic valve implantation (TAVI). BACKGROUND: Revascularization strategy of CAD diagnosed with routine coronary angiography before TAVI is uncertain. METHODS: Five hundred and forty consecutive TAVI patients were classified as having CAD or normal coronary arteries (no-CAD). Within the CAD group, patients were further classified as those with complete (CR) versus incomplete revascularization (IR). Revascularization strategy was guided by the Heart Team following an algorithm largely based on current guidelines. Main outcome of interest was the incidence of 5-year cardiovascular (CV) death. RESULTS: Prevalence of CAD was 53.9%. CAD patients showed significantly lower left ventricular ejection fraction (LVEF: 55.8 ± 13.4% CAD vs. 61.4% ± 12.1 no-CAD, p < .0001), lower gradients, and larger ventricular volumes in comparison with the no-CAD group. Within the CAD group, 138 patients (47.4%) received CR and 153 (52.6%) IR. In-hospital mortality was 3.9%, without significant difference between groups (4.0% no-CAD vs. 3.8% CAD, p = .88; 2.9% CR vs. 4.6% IR, p = .45). Median follow-up was 57.8 months. Five-year survival free from CV death was 79.6% in the CAD versus 77.9% in the no-CAD group (p = .98), and 84.3% in the CR versus 74.3% in the IR groups (p = .25). These results were confirmed excluding patients with previous revascularization. At multivariable analyses, presentation with acute coronary syndrome (ACS) was significantly associated with 5-year CV death. CONCLUSIONS: CAD is frequent in patients undergoing TAVI but portends an adverse prognosis only when presenting with ACS. Heart-team directed complete or reasonably incomplete revascularization was associated with comparable outcomes.

OBJECTIVES: To define the incidence of vascular complications (VC) after balloon aortic valvuloplasty (BAV) in recent years, and to compare the performance of two vascular closure devices (VCD). BACKGROUND: VC remain the most frequent drawback of BAV and are associated with adverse clinical outcomes. METHODS: All BAV procedures performed at 2 high-volume centers over a 6-year period (n = 930) were collected in prospective registries and investigated to assess the incidence of Valve Academic Research Consortium-2 (VARC-2) defined VC. Incidence of life-threatening, major and minor bleeding was also assessed. In-hospital major adverse cardiac and cerebrovascular events (MACCE) rate (composite of in-hospital death, myocardial infarction, TIA/stroke, and life-threatening bleeding) as well as 30-day survival was compared between a suture-mediated closure system and a collagen plug hemostatic device. RESULTS: A 9 Fr arterial sheath was used in most of the patients (84.1%). Vascular closure was obtained with the Angio-Seal in 643 patients (69.1%) and the ProGlide in 287 (30.9%). The overall incidence of major VC was 2.7%, and minor VC 6.6%, without significant differences between groups. The Angio-Seal group was associated with a higher rate of small hematomas (6.9% vs. 3.5%, P = 0.042), whilst blood transfusions were more frequent in the ProGlide group (6.6% vs. 3.5%, P = 0.034). Rates of in-hospital MACCE and 30-day survival were similar. Use of either VCD was not independently associated with major VC. CONCLUSIONS: VC rate after BAV is fairly low in experienced centers without major differences between the 2 most used VCD.

OBJECTIVES: To compare the effectiveness and safety of balloon aortic valvuloplasty (BAV) performed with or without rapid ventricular pacing (RP). BACKGROUND: BAV technique is poorly standardized. METHODS: One hundred consecutive patients were randomly assigned 1:1 between BAV performed with or without RP. Exclusion criteria were an immediate indication for surgical or transcatheter aortic valve replacement, presentation in cardiogenic shock or pulmonary edema refractory to medical stabilization. RESULTS: There were 51 patients in the BAV group performed with RP, 49 in the BAV group without RP (noRP). Procedural success (50% hemodynamic gradient reduction) was achieved in 37.3% and 55.1%, respectively (P = 0.16). Fewer people in the noRP group complained of poor tolerance to the procedure (16% vs 41%). The primary efficacy endpoint, a 50% reduction in the mean echocardiographic trans-aortic gradient, was met in 21/49 patients in the noRP group compared to 20/51 in the RP (42.9% vs 39.2%; P = 0.84). No significant difference between the groups was observed in the primary safety endpoint, a 30-day composite of death, myocardial infarction, stroke, acute aortic regurgitation, and BARC bleeding ≥3 (8.2% noRP vs 13.7%; P = 0.53). The noRP group required fewer bailout temporary pacemakers (P = 0.048) and had a lower incidence of moderate/severe renal function worsening (4.1% vs 17.6%; P = 0.052). CONCLUSIONS: Rapid ventricular pacing did not influence BAV efficacy or safety and tolerance was slightly worse.

OBJECTIVES: To evaluate the incidence, treatment, and outcomes of acute aortic regurgitation (ARR) complicating BAV. BACKGROUND: In the transcatheter aortic valve implantation (TAVI) era, there is an increase of percutaneous balloon aortic valvuloplasty (BAV) procedures with different indications. METHODS: From the prospective BAV registry of the University of Bologna, which has enrolled patients between the year 2000 and the present, we selected those who suffered intraprocedural AAR with overt hemodynamic instability. Worsening of baseline aortic insufficiency without hemodynamic collapse, treatment of degenerated biological valve prosthesis, and BAV performed within a planned TAVI procedure were excluded. The main endpoints were in-hospital and 30-day mortality. RESULTS: Out of 1517 BAVs, we identified 26 cases of AAR (1.7%). This complication occurred in 80.8% of cases after one or two balloon inflations. Mean transaortic gradient decreased from 50.6 ± 19.3 to 26.0 ± 14.4 mm Hg (p < 0.01). In 8(30.8%) patients, AAR spontaneously resolved within few minutes; in 18 cases, the operators had to perform a rescue maneuver to reposition a valve leaflet got stuck in the opening position (this maneuver was successful in 13/18 of the cases, 72.2%). Out of 5 persistent AAR, 3 were managed with emergency TAVI or surgery, while 2 were unresolved. In-hospital mortality was 15.4% (n = 4), whereas no more deaths occurred up to 30 days. CONCLUSIONS: AAR is a fearsome complication of BAV and portends a grim prognosis. In some cases, it can be resolved with appropriate technical maneuvers; in others, a rescue TAVI or surgical valve replacement may be necessary. © 2015 Wiley Periodicals, Inc.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is an effective therapeutic option for patients with severe aortic stenosis at high risk for surgery. Identification of causes of death after TAVR may help improve patient selection and outcome. METHODS: We enrolled 874 consecutive patients who underwent TAVR at 3 centers using all approved bioprostheses and different access routes. Clinical outcomes during follow-up were defined according to the Valve Academic Research Consortium 2 definitions. Causes of deaths were carefully investigated. RESULTS: Mean logistic European System for Cardiac Operative Risk Evaluation was 23.5% ± 15.3%; Society of Thoracic Surgery score, 9.0% ± 8.2%. The Corevalve (Medtronic, Minneapolis, MN) was used in 41.3%; the Edwards Sapien (Edwards Lifesciences Inc., Irvine, CA) in 57.3%. Vascular access was transfemoral in 75.7%. In-hospital mortality was 5.0%. Cumulative mortality rates at 1 to 3 years were 12.4%, 23.4%, and 31.5%, respectively. Landmark analysis showed a significantly higher incidence of cardiovascular (CV) death in the first 6 months of follow-up and a significantly higher incidence of non-CV death thereafter. At Cox regression analysis, the independent predictors of in-hospital mortality were acute kidney injury grades 2 to 3 (hazard ratio [HR] 3.41) life-threatening bleeding (HR 4.26), major bleeding (HR 4.61), and myocardial infarction (HR 3.89). The independent predictors of postdischarge mortality were chronic obstructive pulmonary disease (HR 1.48), left ventricular ejection fraction at discharge (HR 0.98), and glomerular filtration rate <30 mL/min per 1.73 m(2) (HR 1.64). CONCLUSIONS: Around a third of patients treated with TAVR in daily practice die within the first 3 years of follow-up. Early mortality is predominantly CV, whereas late mortality is mainly non-CV, and it is often due to preexisting comorbidity.

Transcatheter aortic valve implantation (TAVI) in native pure aortic regurgitation (AR) with off-label use of balloon-expandable valves (BEV) has been reported. However, there are scant data regarding optimal oversizing and its safety, and our study assessed BEV oversizing and outcomes of TAVI. Thirteen consecutive tricuspid aortic valve patients who underwent transfemoral TAVIs for pure AR with Sapien BEV at our center between 2019 and 2023 (69.2% males, mean age 80.8 years, Society of Thoracic Surgeons 4.0%) were divided into small annulus (SA) group (≤618 mm2) where ≥20% oversizing is achievable based on published data on BEV overexpansion, and larger annulus (LA) group (>618 mm2). Overexpansion and actual oversizing were measured on postprocedural computed tomography scan. Technical success was 92.3% with 1 valve embolization in the LA group. The postprocedural computed tomography showed a mean 28.3% oversizing, significantly higher in SA (31.2%) than in LA group (19.4%), p = 0.0092. Oversizing ≥20% was achieved in 100% SA versus 33.3% LA patients (p = 0.046). In conclusion, TAVI in pure AR with oversized Sapien BEV showed good procedural and short-term outcomes when ≥20% oversizing was predictably achievable.

OBJECTIVES: To investigate the prognostic significance of baseline white blood cell count (WBCc) in non-ST-segment elevation acute coronary syndrome (NSTE-ACS) and its additive predictive value beyond the Global Registry of Acute Coronary Events (GRACE) score. METHODS: We included 1,315 consecutive NSTE-ACS patients. Patients were divided in quartiles according to the WBCc (cells per 1 mm(3)) i.e. Q1 <6,850, Q2 = 6,850-8,539, Q3 = 8,540-10,857 and Q4 ≥10,858. The study end point was 3-year cardiovascular death (CVD). RESULTS: The median age of the study population was 76 years. Overall, 335 patients (25.5%) died with 211 of these (16%) suffering from CVD. Patients in Q4 showed a higher cumulative probability of CVD compared to patients in Q1-Q3. On multivariable analysis, patients in Q4 were at higher risk of CVD [hazard ratio (HR) = 1.47, 95% confidence interval (CI) 1.09-1.98, p = 0.011]. WBCc as a continuous variable was also independently associated with the study end point (HR = 1.043; 95% CI 1.02-1.07; p = 0.001). However, the incorporation of WBCc into the GRACE score did not improve either prediction of risk (C-index = 0.796 for GRACE score with or without WBCc) or classification of risk [relative integrated discrimination improvement = 0.0154, 95% CI) -0.029 to 0.0618; continuous net reclassification improvement = -0.0676, 95% CI -0.2149-0.0738). CONCLUSIONS: WBCc was an independent predictor of 3-year CVD in patients with NSTE-ACS. However, it did not add prognostic information beyond the GRACE score.

AIMS: Several causes have been reported for coronary artery ectasia (CAE), mostly atherosclerosis and tunica media abnormalities. The main aim of the present study was to investigate if CAE extension differs in distinct clinical settings. METHODS: Three hundred and forty-one patients with diagnosis of CAE were identified among 9659 coronary angiographies and divided into four groups according to the patient's admission diagnosis: stable or unstable angina (S-UA), myocardial infarction (MI), aortic disease, aortic valvular disease (AVD). S-UA and MI were subgrouped according to the presence of obstructive coronary artery disease (OCAD). Multivariable logistic regression was used to investigate the relationship between clinical diagnosis and CAE extension as expressed by Markis classification and number of coronary vessels affected by CAE. RESULTS: No significant differences in CAE extension were found among the four groups, in terms of vessels affected by CAE (Pâ=â0.37) or Markis class (Pâ=â0.33). CAE was not related to the extension of OCAD as assessed by the Gensini score, which was higher in MI and S-UA groups (Pâ<â0.01). However, when ischemic patients were sub-divided on the basis of the presence of OCAD, MI without obstructive coronary artery disease (MINOCA) was associated with a higher extension of CAE in terms of Markis class 1 (OR 5.08, 95% CI 1.61-16.04; Pâ<â0.01). CONCLUSION: The extension of CAE is comparable in patients referred to coronary angiography for different clinical scenarios, including S-UA, MI, aortic disease, and AVD; however, patients with MINOCA were associated with a higher extension of CAE.Graphical abstract: Difference in coronary artery ectasia extension in terms of Markis class severity, respectively, stratified by clinical presentation and obstructive coronary artery disease presence, http://links.lww.com/JCM/A519.

BACKGROUND: The optimal access route in patients with severe peripheral artery disease (PAD) undergoing transcatheter aortic valve replacement (TAVR) remains undetermined. OBJECTIVES: This study sought to compare clinical outcomes with transfemoral access (TFA), transthoracic access (TTA), and nonthoracic transalternative access (TAA) in TAVR patients with severe PAD. METHODS: Patients with PAD and hostile femoral access (TFA impossible, or possible only after percutaneous treatment) undergoing TAVR at 28 international centers were included in this registry. The primary endpoint was the propensity-adjusted risk of 30-day major adverse events (MAE) defined as the composite of all-cause mortality, stroke/transient ischemic attack (TIA), or main access site-related Valve Academic Research Consortium 3 major vascular complications. Outcomes were also stratified according to the severity of PAD using a novel risk score (Hostile score). RESULTS: Among the 1,707 patients included in the registry, 518 (30.3%) underwent TAVR with TFA after percutaneous treatment, 642 (37.6%) with TTA, and 547 (32.0%) with TAA (mostly transaxillary). Compared with TTA, both TFA (adjusted HR: 0.58; 95% CI: 0.45-0.75) and TAA (adjusted HR: 0.60; 95% CI: 0.47-0.78) were associated with lower 30-day rates of MAE, driven by fewer access site-related complications. Composite risks at 1 year were also lower with TFA and TAA compared with TTA. TFA compared with TAA was associated with lower 1-year risk of stroke/TIA (adjusted HR: 0.49; 95% CI: 0.24-0.98), a finding confined to patients with low Hostile scores (Pinteraction = 0.049). CONCLUSIONS: Among patients with PAD undergoing TAVR, both TFA and TAA were associated with lower 30-day and 1-year rates of MAE compared with TTA, but 1-year stroke/TIA rates were higher with TAA compared with TFA.

OBJECTIVES: To assess safety and effectiveness of balloon aortic valvuloplasty (BAV) in patients with symptomatic severe aortic stenosis (AS) and significant aortic regurgitation. BACKGROUND: BAV is a palliative procedure that has possibly been underused in patients with symptomatic AS not suitable for surgical aortic valve replacement or transcatheter aortic valve implantation. Significant aortic regurgitation is commonly perceived as a contraindication to BAV. METHODS: Among 416 consecutive patients undergoing BAV at our Institution, 73 patients showed moderate or severe AR before the procedure. Demographics and baseline characteristics, as well as in-hospital clinical outcome, have been prospectively collected in a dedicated database. Transthoracic echocardiography was regularly performed in all patients undergoing BAV before the procedure and at hospital discharge. RESULTS: Patients had a high-risk profile, confirmed by advanced age (77.2 ± 11.8 years) and important comorbidity (logistic Euroscore 26.5 ± 16.3%). Advanced heart failure was present in 73.9%. Indication to BAV was cardiogenic shock in 9.6%, palliation in 31.5%, bridge in 58.9% of the patients. BAV was performed with standard retrograde approach. Aortic valve area increased from 0.62 ± 0.15 cm(2) at baseline to 0.83 ± 0.17 cm(2) before discharge (P < 0.001). The degree of AR was improved or unchanged in 65 patients (89%). In-hospital mortality was 6.9%, mainly limited to terminal patients. Symptomatic status at discharge was improved in all surviving patients. Acute AR occurred in seven patients; in five of them it was successfully resolved in the catheterization laboratory. CONCLUSIONS: When clinically indicated, BAV can be safely performed in patients with combined aortic stenosis and significant aortic regurgitation.

AIMS: To investigate gender difference in mortality among patients with ST-segment elevation myocardial infarction (STEMI) treated with primary percutaneous angioplasty (PPCI). METHODS: We analyzed data from the prospective registries of two hub PPCI centres over a 10-year period to assess the role of female gender as an independent predictor of both all-cause and cardiac death at 30 days and 1 year. To account for all confounding variables, a propensity score (PS)-adjusted multivariable Cox regression model and a PS-matched comparison between the male and female were used. RESULTS: Among 4370 consecutive STEMI patients treated with PPCI at participating centres, 1188 (27.2%) were women. The survival rate at 30 days and 1 year were significantly lower in women (Log-rank P-valueâ<â0.001). At PS-adjusted multivariable Cox regression analysis, female gender was independently associated with an increased risk of 30-day all-cause death [hazard ratio (HR)â=â2.09; 95% confidence interval (CI): 1.45-3.01, Pâ<â0.001], 30-day cardiac death (HRâ=â2.03;95% CI:1.41-2.93, Pâ<â0.001), 1-year all-cause death (HRâ=â1.45; 95% CI:1.16-1.82, Pâ<â0.001) and 1-year cardiac death (HRâ=â1.51; 95% CI:1.15-1.97, Pâ<â0.001). For the study outcome, we found a significant interaction of gender with the multivessel disease in females who were at increased risk of mortality in comparison with men in absence of multivessel disease. After the PS matching procedure, a subset of 2074 patients were identified. Women still had a lower survival rate and survival free from cardiac death rate both at 30-day and at 1-year follow-up. CONCLUSION: As compared with men, women with STEMI treated with PPCI have higher risk of both all-cause death and cardiac mortality at 30-day and 1-year follow-up.

We report the case of a total endovascular repair of an aortic arch aneurysm by a custom-made endograft with three inner branches for supra-aortic trunks in a high-risk patient unfit for open surgery. An 82-year-old female at high risk for open repair was treated for an asymptomatic aortic arch aneurysm (97 mm in diameter) by a custom-made three-inner branched endograft. Two anterograde branches were planned for the innominate trunk and the left carotid artery while a retrograde branch with a preloaded catheter was planned for the left subclavian artery. The procedure was successfully completed and postoperative course was uneventful. Computed tomography angiography demonstrated aneurysm exclusion, patency of the three supra-aortic branches and absence of cerebral ischemic lesion at 30 and 90 days. A custom-made endovascular device with three inner branches is a safe and effective option to guarantee a total endovascular repair of aortic arch aneurysm in high-risk patients in the presence of anatomical feasibility.

BACKGROUND: Aortic aneurysms are associated with coronary artery ectasia (CAE). However, the relation between the extent of CAE and the severity of aortic dilatation is not understood. This study was undertaken to investigate the relationship between angiographic extension of CAE and aortic dimension. PATIENTS AND METHODS: We retrospectively include 135 patients with angiographic diagnosis of CAE defined as dilatation of coronary segment more than 1.5 times than an adjacent healthy one. Study population was divided in four groups according to the maximum diameter of ascending aorta beyond sinus of Valsalva obtained in the parasternal long-axis view (group 1: <40 mm; group 2: 40-45 mm; group 3: 45-55 mm; group 4: >55 mm or previous surgery because of aortic aneurysm/dissection). The relationship between aortic dimension and the extension of CAE was investigated by means of multivariable linear regression, including variables selected at univariable analysis (P < 0.1). The total estimated ectatic area (EEA total) was used as dependent variable. RESULTS: Baseline characteristics of study groups were well balanced. Patients in group 4 were more likely to have both higher neutrophil count and neutrophil to lymphocyte ratio. On univariable analysis ascending aorta diameter [Coef. = 0.075; 95% confidence interval (CI) 0.052-0.103, P < 0.01] and c-reactive protein (CRP) values [Coef. = 0.033, 95% CI 0.003-0.174, P = 0.04] showed a linear association with total EEA. After adjustment for CRP values only the ascending aorta diameter was still associated with the extent of CAE (95% CI 0.025-0.063, P < 0.01). CONCLUSION: In patients with diagnosis of CAE, a strong linear association between aortic dimension and coronary ectasia extent exists.

BACKGROUND: Coronary artery ectasia (CAE) is associated with ascending aortic (AA) ectasia. The purpose of this study is to evaluate the diagnostic performance of different echocardiographic parameters (EP) in predicting the presence of CAE. METHODS: Four hundred-eighteen patients with AA ectasia candidate to coronary angiography were identified and divided in two groups in respect of the presence of CAE. Receiver-operating characteristic curves areas (AUC) were used to assess the discrimination power of the following EP: aortic annulus diameter, sinuses of Valsalva (SV) diameter, sino-tubular junction (STJ) diameter, AA diameter, STJ to SV ratio (STJ-to-SV) and STJ to AA ratio (STJ-to-AA). All these parameters were indexed by body surface area. The relationship between the best EP and the presence of CAE was investigated by means of multivariable logistic regression. RESULTS: The rate of CAE in the study population was 32%. On univariable logistic regression, aortic annulus, STJ, STJ-to-SV and STJ-to-AA were associated with the presence of CAE after Bonferroni correction. STJ-to-SV emerged as the parameter with the best discrimination power (AUC = 0.81) compared to STJ (AUC = 0.69), STJ-to-AA (AUC = 0.68), aortic annulus (AUC = 0.59), AA (AUC = 0.56) and SV (AUC = 0.55); (p for comparison <0.01). An 89.6% value for STJ-to-SV ratio emerged as the best cut-off to diagnose CAE with a sensitivity = 75%, specificity = 82%, positive predictive value = 66% and negative predictive value = 88%. On multivariable analysis, STJ-to-SV was still associated with the presence of CAE (OR = 1.15;95%CI:1.11-1.19;p < 0.01). CONCLUSION: In patients with dilated aorta, STJ-to-SV sampled by transthoracic echocardiography shows a good diagnostic performance in predicting the presence of CAE.

AIMS: To evaluate the clinical impact of early administration of glycoprotein IIb/IIIa agents (IIb/IIIa agents) in the context of a dedicated hub and spoke network allowing very prompt pharmacological/mechanical interventions. METHODS AND RESULTS: Using a prospective database, we conducted a cohort study of ST-elevation myocardial infarction (STEMI) patients (n = 1124) undergoing primary percutaneous coronary interventions (PPCIs) and IIb/IIIa agents administration (period, 2003-2006). Comparisons were planned between patients receiving early IIb/IIIa agents administration (in hub/spoke centre emergency departments or during ambulance transfer; early group, n = 380) or delayed administration (in the catheterization laboratory; late group, n = 744). The primary outcome measure was long-term overall mortality/re-infarction. Baseline characteristics of the two groups were largely comparable. Angiographically, early group patients more often achieved pre-PPCI TIMI Grade 2-3 and TIMI Grade 3 flow. Clinically, the early administration group experienced lower 2-year risk of unadjusted mortality/re-infarction (17 vs. 23%; P = 0.01). After adjustment for potential confounders, early administration was associated with favourable outcome in the overall population (HR = 0.71, P = 0.03) and in high-risk subgroups (TIMI risk index >25, HR = 0.64, P = 0.02; Killip class >1, HR = 0.54, P = 0.01). CONCLUSION: In patients treated by PPCI within a STEMI network setting, early administration of IIb/IIIa agents may provide long-term clinical benefits. Notably, these results appeared magnified in high-risk patients.
