RESUMO

BACKGROUND: Cardiac allograft vasculopathy (CAV) is an important cause of late mortality after heart transplantation, which may be influenced by preexisting coronary disease (CAD) in the donor heart. METHODS: The aim of this study was to verify whether CAD in the donor heart had any influence on survival, cardiac-related adverse events (CRAEs), and coronary disease progression after transplantation. Donor coronary angiography performed in 289 hearts showed absence of CAD in 232 (no-CAD group) and moderate (≤50%) stenoses (CAD group) in 57. The 2 groups were compared for survival, freedom from CRAEs, and development of grade ≥ 2 CAV after transplantation. RESULTS: Of 30-day mortality and postoperative complication rate was similar as mean follow-up (76 ± 56 and 75 ± 55 months) for no-CAD and CAD (P = 0.8). Ten-year actuarial survival was 58 ± 4% and 62 ± 7% for no-CAD and CAD (P = 0.4). Ten-year freedom from grade ≥ 2 CAV and from CRAEs was 81 ± 4% and 66 ± 5% vs 75 ± 8% and 67 ± 9% in no-CAD and CAD (P = 0.9 and 0.9, respectively). CONCLUSIONS: Donor hearts with moderate CAD did not affect survival, freedom from CRAEs and did not accelerate development of high-grade CAV after transplantation supporting the use of such grafts to expand the donor pool. Routine use of coronary angiography in donor selection appears justified.

RESUMO

BACKGROUND: Cardiac allograft vasculopathy (CAV) is still the main drawback of heart transplantation (HTx) and percutaneous coronary intervention (PCI) is a palliative measure because of the high incidence of failure. OBJECTIVE: This study aimed to investigate the safety and efficacy of bioresorbable scaffolds (BRSs) as potential novel therapeutic tool for the treatment of coronary stenoses in CAV. METHODS: This is a multicenter, single-arm, prospective, open-label study (CART, NCT02377648), that included patients affected by advanced CAV treated with PCI and second-generation ABSORB BRS (Abbott Vascular). The primary endpoint was the incidence of 12-month angiographic in-segment scaffold restenosis (ISSR). Secondary endpoints were the incidence of major adverse cardiac events (MACEs) at 12- and 36-month follow-up and the incidence of ISSR at 36 months. A paired intracoronary imaging analysis at baseline and follow-up was also performed. RESULTS: Between 2015 and 2017 35 HTx patients were enrolled and treated for 44 coronary lesions with 51 BRSs. The primary endpoint occurred in 13.5% of the lesions (5/37), with a cumulative ISSR rate up to 3 years of 16.2% (6/37). Angiographic lumen loss was 0.40 ± 0.62 mm at 12 months and 0.53 ± 0.57 mm at 36 months. Overall survival rate was 91.4% and 74.3%, and MACEs incidence 14.2% and 31.4% at 12 and 36 months, respectively. At the paired intracoronary imaging analysis, a significant increase of the vessel external elastic membrane area in the treated segment and some progression of CAV proximally to the BRS were detected. CONCLUSIONS: BRS-based PCI for the treatment of CAV is feasible and safe, with an ISSR incidence similar to what reported in retrospective studies with drug-eluting stents.

RESUMO

The COVID-19 global pandemic has changed considerably the way time-sensitive disorders are treated. Home isolation, people's fear of contracting the virus and hospital reorganisation have led to a significant decrease in contacts between citizens and the healthcare system, with an expected decrease in calls to the Emergency Medical Services (EMS) of the Friuli-Venezia Giulia (FVG) region. However, mortality in clinical emergencies like acute ST-elevation myocardial infarction (STEMI), stroke and out-of-hospital cardiopulmonary arrest (OHCA) remained high. An observational retrospective cross-sectional study was carried out in FVG, taking into account the period between March 1, 2020, and May 31, 2020, the first wave of the COVID-19 pandemic, and comparing it with the same period in 2019. The flow of calls to the EMS was analysed and COVID-19 impact on time-sensitive disorders (STEMIs, ischemic strokes and OHCPAs) was measured in terms of hospitalisation, treatment and mortality. Despite a -8.01% decrease (p value ˂0.001) in emergency response, a 10.89% increase in calls to the EMS was observed. A lower number of advanced cardiopulmonary resuscitations (CPR) (75.8 vs 45.2%, p=0.000021 in April) and ROSC (39.1 vs 11.6%, p=0.0001 in April) was remarked, and survival rate dropped from 8.5 to 5%. There were less strokes (-27.5%, p value=0.002) despite a more severe onset of symptoms at hospitalisation with NHISS˃10 in 38.47% of cases. Acute myocardial infarctions decreased as well (-20%, p value=0.05), but statistical significances were not determined in the variables considered and in mortality. Despite a lower number of emergency responses, the number of calls to the EMS was considerably higher. The number of cardiac arrests treated with advanced CPR (ALS) was lower, but mortality was higher. The number of strokes decreased as well, but at the time of hospitalisation the clinical picture of the patient was more severe, thus affecting the outcome when the patient was discharged. Finally, STEMI patients decreased; however, no critical issues were observed in the variables taken into account, neither in terms of response times nor in terms of treatment times.

RESUMO

OBJECTIVES: The aim of our study is to evaluate the safety and efficacy of DES implantation in an unselected, "real world," high-risk population. BACKGROUND: Several clinical trials showed that drug-eluting stents (DESs) implantation is safe and effective in selected population. In spite of these encouraging results, there are some concerns about "real world" utilization of these stents. METHODS: One thousand four hundred and fifty-five off-label patients have been included in our registry. Primary end-points were: long-term clinical incidence of major adverse cardiac and cerebrovascular events (MACCE) and thrombosis (ST). We detected the difference between uniDES vs. multiDES implantation in terms of MACCE, death, nonfatal-MI, the composite of death/nonfatal-MI and target lesion revascularization (TLR) and the difference between DES type in term of MACCE. RESULTS: At 36 months follow-up we found: cardiac death occurred in 20 patients (1.6%); 33 patients (2.6%) had a nonfatal MI and 81 patients (6.3%) had a TLR. We observed one (0.1%) acute, 9 subacute (0.6%), 6 late (0.6%), and 1 (0.5%) very late definite ST. No difference were found in terms of overall MACCE, MI, death and composite of death/nonfatal-MI between uni- and multiDES implantation but multiDES group had a higher incidence of TLR. No difference between DES type in term of MACCE was detected. CONCLUSIONS: DES utilization shows their safety and efficacy in off-label patients with complex clinical and angiographic profile in terms of long-term incidence of MACCE. MultiDES implantation is associated with a higher risk of long-term TLR. No difference between DES type was found.

RESUMO

Spontaneous coronary artery dissection (SCAD) is increasingly recognized as an important cause of myocardial infarction (MI). Currently there is little knowledge about prognostic factors for unfavorable outcome at long term follow-up; furthermore, there is also little knowledge about the genetics of these patients. AIMS: This observational and retrospective study describes long-term cardiovascular outcomes of a population affected by SCAD and assesses predictors of recurrent de novo SCAD and major adverse cardiovascular events (MACE). Furthermore, a correlation between genotype and adverse events at follow-up was sought. METHODS: Baseline characteristics, angiographic features, use of medication and long-term cardiovascular events were systematically ascertained between 2000 and 2019. Next generation sequencing was performed with a panel consisting of twenty genes of interest. Variants found were filtered based on their frequency and only frequencies <1% in the general population were considered as "positive". RESULTS: Seventy patients were enrolled and followed for a median time of 39.1 months. Median age was 52 years and the majority were women (86%). Use of hormone therapy (HT) (OR 3.64, p = 0.041) and presence of malignant ventricular arrhythmias (VAs) at onset (OR 7.03, p = 0.0073) were associated with a greater risk of recurrent de novo SCAD. Proximal type SCAD (OR 8.47, p < 0.0001) and presence of VAs at onset (OR 9.97, p = 0.047) were associated with a greater risk of MACE. A potential SCAD-associated mutation was detected in 27 patients (44%); 6 patients (22%) defined as genetically "positive" developed MACE vs. 2 patients (6%) defined as "negative" (p = 0.06 at univariate analysis). MACE at follow-up is reached earlier in genetically positive patients (7.9 vs. 42.5 months). CONCLUSION: use of HT and VAs at SCAD onset are prognostic factors for recurrent de novo SCAD. Proximal SCAD site and VAs at SCAD onset were prognostic factors for MACE. Analysis by molecular genetics seems to be a promising tool for the possible additional role it could play in MACE prediction.

RESUMO

Data regarding the potential influence of gender on outcomes of rotational atherectomy (RA) percutaneous coronary intervention (PCI) are scarce and conflicting. Using the Euro4C registry, an international prospective multicentric registry of RA PCI, we evaluated the influence of gender on clinical outcomes of RA PCI. Between October 2016 and July 2018, 966 patients were included. In them, 267 (27.6%) were females. Female patients were older than males (77.7 years old ± 9.8 vs 73.3 ± 9.5 years old respectively, p < 0.001) had a poorer renal function (43,1% of females had a GFR < 60 ml/min:1.73m² vs 30.4% of males, p < 0.001) and were more frequently admitted for an acute coronary syndrome (32.2% vs 22.3% p = 0.002). During RA procedure, women were less likely to be treated by radial approach (65.0% vs 74.4%, p = 0.004). In-hospital major adverse cardiac event rate-defined as cardiovascular death, myocardial infarction, stroke/transient ischemic attack, target lesion revascularization, and coronary artery bypass grafting surgery-was higher in the female group (7.1% vs 3.7%, p = 0.043). However, coronary perforation, dissection, slow/low flow and tamponade did not significantly differ in gender, neither did cardiovascular medications at discharge. At 1 year follow-up, rate of major adverse cardiac event was 18.4% in the female group vs 11.2% in the male group (adjusted Hazard Ratio 1.82 [1.24 to 2.67], p = 0.002). No significant bleeding differences were observed in gender, neither in hospital, nor during follow-up. In conclusion women had worse clinical outcomes following RA PCI during hospitalization and at 1 year follow-up than did men.

RESUMO

AIM: To compare the long-term outcomes of patients implanted with Absorb bioresorbable scaffold (BRS) with optimal versus suboptimal technique. METHODS AND RESULTS: All patients who received an Absorb between March 2012 and January 2016 were selected from 19 Italian centers databases to assess the impact of an optimal implantation technique (CIAO criteria) on long-term device-oriented composite end-point (DOCE) - including cardiac death (CD), target-vessel myocardial infarction (TV-MI) and ischemia-driven target lesion revascularization (ID-TLR) - on its single components and on scaffold thrombosis (ScT). CIAO criteria consist of predilation (balloon/vessel ratio 1:1), correct sizing (BRS/proximal reference vessel diameter -RVD- ratio 0.8-1.2) and high-pressure postdilation with non-compliant (NC) balloon (≥20 atm for balloon/BRS ratio 1:1 or ≥16 atm for a 0.25-0.5 mm oversized balloon). Among the 1.434 patients analyzed, 464 (32.4%) fulfilled all CIAO criteria for every BRS implanted (CIAO 3 group), while 970 (67.6%) did not in at least one of the received BRS (CIAO 0-1-2 group). At 31.0 (interquartile range -IQR- 24.8-38.5) months follow-up, CIAO criteria did not impact on DOCE (8.2% vs. 8.0%, p = 0.92), ID-TLR (6.9% vs. 7.1%, p = 0.72) or ScT (1.9% vs. 1.8%, p = 0.80) in the overall population. At multivariate analysis overall BRS length (p = 0.001), severely calcified lesions (p = 0.03) and absence of CIAO criteria (CIAO 0, p = 0.005) were independent predictors of DOCE in long-term follow-up. CONCLUSION: Our data suggest that strict application of an optimal Absorb implantation technique doesn't improve long-term DOCE or ScT but may mitigate the worse outcome of patients with calcific lesions.

RESUMO

BACKGROUND AND AIMS: SARS-Cov-2 predisposes patients to thrombotic complications, due to excessive inflammation, endothelial dysfunction, platelet activation, and coagulation/fibrinolysis disturbances. The aim of the present study was to evaluate clinical characteristics and prognostic impact of SARS-CoV-2 positivity among STEMI patients undergoing primary percutaneous coronary intervention (PPCI). METHODS: We selected SARS-CoV-2 positive patients included in the ISACS-STEMI COVID-19, a retrospective multicenter European registry including 6609 STEMI patients treated with PPCI from March 1st until April 30th, in 2019 and 2020. As a reference group, we randomly sampled 5 SARS-Cov-2 negative patients per each SARS-CoV-2 positive patient, individually matched for age, sex, and hospital/geographic area. Study endpoints were in-hospital mortality, definite stent thrombosis, heart failure. RESULTS: Our population is represented by 62 positive SARS-CoV-2 positive patients who were compared with a matched population of 310 STEMI patients. No significant difference was observed in baseline characteristics or the modality of access to the PCI center. In the SARS-CoV-2 positive patients, the culprit lesion was more often located in the RCA (p < 0.001). Despite similar pre and postprocedural TIMI flow, we observed a trend in higher use of GP IIb-IIIa inhibitors and a significantly higher use of thrombectomy in the SARS-CoV-2 positive patients. SARS-CoV-2 positivity was associated with a remarkably higher in hospital mortality (29% vs 5.5%, p < 0.001), definite in-stent thrombosis (8.1% vs 1.6%, p = 0.004) and heart failure (22.6% vs 10.6%, p = 0.001) that was confirmed after adjustment for confounding factors. CONCLUSIONS: Our study showed that among STEMI patients, SARS-CoV-2 positivity is associated with larger thrombus burden, a remarkably higher mortality but also higher rates of in-stent thrombosis and heart failure.

RESUMO

BACKGROUND: The fear of contagion during the coronavirus disease-2019 (COVID-19) pandemic may have potentially refrained patients with ST-segment elevation myocardial infarction (STEMI) from accessing the emergency system, with subsequent impact on mortality. OBJECTIVES: The ISACS-STEMI COVID-19 registry aims to estimate the true impact of the COVID-19 pandemic on the treatment and outcome of patients with STEMI treated by primary percutaneous coronary intervention (PPCI), with identification of "at-risk" patient cohorts for failure to present or delays to treatment. METHODS: This retrospective registry was performed in European high-volume PPCI centers and assessed patients with STEMI treated with PPPCI in March/April 2019 and 2020. Main outcomes are the incidences of PPCI, delayed treatment, and in-hospital mortality. RESULTS: A total of 6,609 patients underwent PPCI in 77 centers, located in 18 countries. In 2020, during the pandemic, there was a significant reduction in PPCI as compared with 2019 (incidence rate ratio: 0.811; 95% confidence interval: 0.78 to 0.84; p < 0.0001). The heterogeneity among centers was not related to the incidence of death due to COVID-19. A significant interaction was observed for patients with arterial hypertension, who were less frequently admitted in 2020 than in 2019. Furthermore, the pandemic was associated with a significant increase in door-to-balloon and total ischemia times, which may have contributed to the higher mortality during the pandemic. CONCLUSIONS: The COVID-19 pandemic had significant impact on the treatment of patients with STEMI, with a 19% reduction in PPCI procedures, especially among patients suffering from hypertension, and a longer delay to treatment, which may have contributed to the increased mortality during the pandemic.

RESUMO

The aim of this work was to evaluate and quantify the impact of an invasive training of cardiology fellows on some exposure parameters. From 1 January 2000 to 31 December 2002, three staff members performed 2.582 diagnostic procedures (Group 1) that were compared with 819 performed by, or with the participation of five cardiology fellows (Group 2). Exposure parameters were as follows (Group 1/Group 2): fluoroscopy time 3.8 +/- 4.5/5.5 +/- 5.9 min (+38%), mean number of frames 589 +/- 282/642 +/- 260 (+9%), Kerma-area product (KAP) during fluoroscopy 10.6 +/- 14/15.5 +/- 16 Gycm2 (+45%), KAP during cine-angiography 20.8 +/- 14/22.5 +/- 12 (+8%), total KAP 31.5 +/- 28/38.1 +/- 28 (+21%). Differences were all significant (P

RESUMO

BACKGROUND: Although octogenarians constitute a fast-growing portion of cardiovascular patients, few data are available on the outcome of patients aged ≥85 years with ST-Elevation Myocardial Infarction (STEMI). METHODS AND RESULTS: We analyzed 126 consecutive patients aged ≥85 years (age 88±2 years) with STEMI, undergoing primary percutaneous coronary intervention (pPCI) within 12 hours from symptoms onset. Long-term follow-up (median 898 days) was obtained for the 102 patients surviving the index-hospitalization. In-hospital mortality rate was 19%. Nonagenarians, diabetes mellitus, severe left ventricular systolic dysfunction and intra-aortic balloon pumping were significantly and independently correlated to in-hospital mortality at the multivariate analysis. A low rate of complications was detected. Among patients surviving the index hospitalization, 32 (31%) patients died during follow-up. 55 patients (54%) had re-hospitalization due to cardiovascular causes. The univariate analysis identified chronic renal failure, Killip class ≥ 3, TIMI Risk Score >8 and very high risk of bleeding as predictors of long-term overall mortality. At the multivariate analysis only chronic renal failure and very high risk of bleeding were significantly and independently correlated to long-term all-cause mortality. Renal function and anterior myocardial infarction were significantly and independently associated with the combined end-point of cardiac mortality and re-hospitalization due to cardiovascular disease at the multivariate analysis. CONCLUSIONS: PPCI in patients ≥85 years old is relatively safe. In this population, pPCI is associated with a good long-term survival, although still worse than in younger patients, despite a considerable incidence of re-hospitalization due to cardiovascular events.

RESUMO

BACKGROUND: In-stent restenosis is notoriously difficult to treat by repeat catheter intervention because of its propensity for aggressive recurrent neointimal formation. This study sought to assess the effectiveness and safety of the sirolimus-eluting stent in the treatment of in-stent restenosis. METHODS AND RESULTS: The study was designed as a prospective multicenter registry. We included 162 patients with in-stent restenosis of a native coronary artery who had a clinical indication for repeat intervention. Patients were scheduled for follow-up angiography at 6 months. The primary end point was in-lesion late loss. Follow-up angiography was performed in 155 patients. We obtained an in-lesion late loss of 0.08+/-0.49 mm and a binary restenosis rate of 9.7% (15/155), which prompted reintervention in 7.4% (12/162) at 9 months. The 9-month rate of death was 1.2% (2/162) and that of nonfatal myocardial infarction was 1.2% (2/162). CONCLUSIONS: Sirolimus-eluting stents were highly efficacious and safe in the treatment of in-stent restenosis. Our study provides rationale for the use of sirolimus-eluting stents in the treatment of in-stent restenosis.

RESUMO

OBJECTIVES: We sought to investigate the success rate and the acute and 12-month clinical outcome of percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) in the contemporary era. BACKGROUND: The technique of PCI involving CTO has improved over time. However, limited data on acute and follow-up results in patients treated with PCI on CTO in recent years are available. METHODS: Four hundred nineteen consecutive patients scheduled for PCI of CTO of > or =30 days of duration were enrolled in 29 centers; 390 CTOs were confirmed in 376 patients in an independent core laboratory. The end points were technical and procedural success, in-hospital and 12-month major adverse cardiac events (MACE) occurrence, and 12-month symptomatic status. RESULTS: Technical and procedural success was obtained in 77.2% and 73.3% of lesions, respectively. In-hospital major adverse cardiac events occurred in 5.1% of patients. Multivariate analysis identified CTO length >15 mm or not measurable, moderate to severe calcifications, duration > or =180 days, and multivessel disease as significant predictors of PCI failure. At 12 months, patients with a successful procedure experienced a lower incidence of cardiac deaths or myocardial infarction (1.05% vs. 7.23%, p = 0.005), a reduced need for coronary artery bypass surgery (2.45% vs. 15.7%, p < 0.0001), and were more frequently free of angina (88.7% vs. 75.0%, p = 0.008) compared with patients who had an unsuccessful procedure. CONCLUSIONS: Successful PCI was achieved in a high percentage of CTOs with a low incidence of complications. At one-year follow-up, patients with successful PCI of a CTO had a significantly better clinical outcome than those whose PCI was unsuccessful.

RESUMO

AIM: An innovative xenon-chlorine (excimer) pulsed laser catheter (ELCA X80) has been recently used for the treatment of complex coronary lesions, as calcified stenosis, chronic total occlusions and non-compliant plaques. Such complex lesions are difficult to adequately treat with balloon angioplasty and/or intracoronary stenting. The aim of this study was to examine the acute outcome of this approach on a cohort of patients with coronary lesions. METHODS AND RESULTS: Eighty patients with 100 lesions were enrolled through four centers, and excimer laser coronary angioplasty was performed on 96 lesions (96%). Safety and effectiveness data were compared between patients treated with standard laser therapy and those treated with increased laser therapy. Laser success was obtained in 90 lesions (93.7%), procedural success was reached in 88 lesions (91.7%), and clinical success in was obtained in 87 lesions (90.6%). There was no perforation, major side branch occlusion, spasm, no-reflow phenomenon, dissection nor acute vessel closure. Increased laser parameters were used successfully for 49 resistant lesions without complications. CONCLUSIONS: This study suggests that laser-facilitated coronary angioplasty is a simple, safe and effective device for the management of complex coronary lesions. Furthermore, higher laser energy levels delivered by this catheter improved the device performance without increasing complications.

RESUMO

STUDY OBJECTIVES: The aim of this study was to evaluate the early and long-term outcomes in patients undergoing aortic root replacement (ARR) with the Bentall procedure. DESIGN: Retrospective study. SETTING: Cardiothoracic surgery unit. PATIENTS AND METHODS: Between January 1986 and January 2002, 72 patients (mean age 58.3 +/- 12.4 years, 81.9% males) underwent ARR by means of a Bentall operation. Annuloaortic ectasia was the most frequent cause of aortic disease in this series of patients (31 patients; 43.1%), followed by type A dissection (19 patients; 26.3%), atherosclerotic aneurysm (18 patients; 25.1%), and poststenotic dilatation (4 patients; 5.5%). Nine patients (12.5%) had Marfan syndrome, and 10 patients (13.8%) underwent a concomitant replacement of the aortic arch. Follow-up ranged from 2 to 192 months (mean [+/- SD], 86.6 +/- 23.8 months). RESULTS: The mean 30-day mortality rate was 5.5 +/- 2%. The mean early mortality rate was 21 +/- 4% and 0% (p < 0.001), respectively, in patients with and without dissecting aortic aneurysms. There were two late deaths that were due to a pulmonary neoplasm and a cerebrovascular accident. The mean 16-year survival rate was 91.7 +/- 3.2%. The mean hazard of freedom from death was constant beyond 3 years (8.5 +/- 3.5%). No patient required reoperation. Furthermore, the long-term clinical follow-up was marked by a complete absence of endocarditis, anticoagulant-related hemorrhage, valve thrombosis, and prosthesis failure. Finally, patients showed a significant improvement in mean New York Heart Association functional status (1.3 +/- 0.1; p < 0.001 [postoperatively vs preoperatively]). CONCLUSIONS: In our experience, the late results of the Bentall operation were satisfactory. Our findings confirm that this technique still represents the procedure of choice for ARR with coronary reimplantation.

RESUMO

BACKGROUND: Little information exists regarding the long-term results of the Cabrol technique. This study aimed at exploring, over a 16-year period, the results of aortic root replacements employing this procedure. METHODS: Between 1986 and 2002 forty-five patients (mean age 58.7 +/- 13.8 years old, 84.4% male) underwent a Cabrol procedure. Aortic dissection was the most frequent cause of aortic disease in this series (n = 17), followed by annuloaortic ectasia (n = 10), atherosclerotic aneurysm (n = 5) and poststenotic dilatation (n = 5). Six patients (13.4%) had undergone a previous aortic operation, 8 (17.7%) had a Marfan syndrome and five (11.1%) underwent concomitant arch replacement. Mean clinical follow-up was 87.3 +/- 24.3 months. Twenty-eight patients (93.3% of survivors) had a transesophageal echocardiography (TEE) performed at a mean of 64 +/- 32 months postoperatively. RESULTS: Early mortality was 20%. It was 9.1% for patients with an ascending aortic aneurysm and 41.2% for dissections (p = 0.026). Independent multivariate predictors of early mortality were: aortic dissection (p = 0.009), emergency operation (p < 0.001), operative year (p = 0.02), cross-clamp time (p = 0.001), and CPB duration (p < 0.001). Actuarial survival was 0.77 +/- 0.06, 0.72 +/- 0.06, 0.59 +/- 0.04 and 0.59 +/- 0.04 at 1, 5, 10, and 16 years, respectively. Multivariate analysis revealed age (p = 0.007), cross-clamp time (p = 0.0006) and CPB duration (p = 0.009) as strong predictors of poor late survival. A periprosthetic jet with significant valve regurgitation was detected by TEE in 3 patients. In one of them, an infected periprosthetic space-right ventricular fistula was demonstrated requiring reoperation. Altogether, freedom from reoperation and endocarditis at 16 years was 0.97 +/- 0.02 and 0.94 +/- 0.03, respectively. CONCLUSIONS: The Cabrol technique demonstrated a nonnegligible incidence of early and long-term complications. It should be rarely used and only when a "button" technique is not feasible.

RESUMO

OBJECTIVE: The purpose of this study was to assess the usefulness of transesophageal echocardiography to detect complications after a Cabrol procedure. METHODS: A total of 28 unselected patients (mean age 52.2 +/- 13.3 years; 86% male) who survived a Cabrol procedure were examined with transesophageal echocardiography at a mean of 64 +/- 32 postoperative months. Underlying diagnosis was Stanford type A dissection in 11% of the patients and nondissecting aneurysm in 89%. RESULTS: Periprosthetic jet as a result of a valve leakage was demonstrated in 3 patients (11%). In 1 patient (4%) with infected aortic graft, a fistula between the periprosthetic space and the right ventricle was detected, requiring reoperation. One patient (4%) showed a complete occlusion of the graft limb of the right coronary artery but did not need reoperation. An aneurysm of the periprosthetic space with perivalvular leakage and persistence of periprosthetic right atrial fistula was visualized in 3 patients (11%). CONCLUSIONS: Our findings encourage the use of transesophageal echocardiography for the follow-up of patients undergoing a Cabrol operation.

RESUMO

The present case report refers to a 65-year-old male patient with subocclusion of the right coronary artery who had an inferior myocardial infarction that was treated with coronary angioplasty. The patient subsequently developed intractable angina pectoris in the absence of critical coronary stenosis at serial coronary angiography. Doppler wire velocity demonstrated an impaired coronary flow reserve. The patient died of cardiogenic shock. Postmortem examination revealed amyloid involvement of the media of the epicardial coronary arteries and severe amyloid deposition in the media and adventitia with obstruction of the lumen of the intramyocardial coronary arteries. Widespread ischemic areas were present in the myocardium with only slight amyloid deposition. In this patient myocardial infarction and unstable angina were a rare initial manifestation of primary amyloidosis.

RESUMO

BACKGROUND: The aim of this study was to evaluate the early and long-term outcomes in patients undergoing a Bentall procedure or its button modification for chronic aortic aneurysms with aortic valve incompetence. METHODS: Between January 1986 and January 2002, 65 patients (84% males, mean age 58.9 +/- 11 years) underwent aortic root replacement with a Bentall or a button-Bentall operation. Annuloaortic ectasia was the most frequent cause of aortic disease in this series (n = 37, 56.9%), followed by atherosclerotic aneurysms (n = 22, 33.9%), and post-stenotic dilation (n = 5, 7.7%). One patient (1.5%) underwent redo aortic root replacement,3 (4.6%) had a Marfan syndrome, and 6 (9.2%) underwent a concomitant replacement of the aortic arch. The duration of follow-up ranged from 2 to 192 months (mean 89.6 +/- 21.8 months). RESULTS: The 30-day mortality was 0%. Early non-fatal complications comprised: bleeding requiring surgical re-exploration (n = 1, 1.5%), low output syndrome (n = 1, 1.5%), acute renal insufficiency (n = 1, 1.5%), transient ischemic attack (n = 2, 3.1%), stroke (n = 1, 1.5%), and pulmonary insufficiency (n = 1, 1.5%). There was a late death due to a pulmonary neoplasm. The 16-year actuarial survival was 97 +/- 2% (hazard 0.02 +/- 0.02). No patient required reoperation. Furthermore, the long-term clinical follow-up was characterized by the complete absence of endocarditis, anticoagulant-related hemorrhage, valve thrombosis, and prosthetic failure. Finally, the NYHA functional status was significantly improved (1.1 +/- 0.50, p < 0.001 vs preoperatively). CONCLUSIONS: The late results of the Bentall and button-Bentall procedures were excellent. Our findings confirm that these techniques still constitute the gold standard in the surgical treatment of combined valve and ascending aorta pathologies.

RESUMO

The technology of bar coding has been recommended because of the ability to increase efficiency. The relative widths of both the bars and spaces code the data stored in the bar code. The Health Industry Business Communications Council (HIBCC) is a non-profit organization aimed at developing appropriate standards to improve exchange among all health care trading partners. According to these recommendations all health care products should be labeled with a primary symbol identifying the labeler and the product code and a secondary one that is useful to distributors and providers. The efficacy of bar code technology depends on the ease of use and the incorporation of user workflow into the system. Despite problems depending on industry factors as well as the lack of standards, resource factors associated with costs for the implementation of the new technology and human factors for cultural exchange that facilitate adoption, it is outstanding that bar code technology improves patient safety and increases organization productivity reducing manual-consuming steps and allowing for more accurate and complete data collection.
