Abstract Background Current guidelines on coronary anomalies are primarily based on expert consensus and a limited number of trials. A gold standard for diagnosis and a consensus on the treatment strategy in this patient group are lacking, especially for patients with an anomalous origin of a coronary artery from the opposite sinus of Valsalva (ACAOS) with an interarterial course. Aim To provide evidence-substantiated recommendations for diagnostic work-up, treatment and follow-up of patients with anomalous coronary arteries. Methods A clinical care pathway for patients with ACAOS was established by six Dutch centres. Prospectively included patients undergo work-up according to protocol using computed tomography (CT) angiography, ischaemia detection, echocardiography and coronary angiography with intracoronary measurements to assess anatomical and physiological characteristics of the ACAOS. Surgical and functional follow-up results are evaluated by CT angiography, ischaemia detection and a quality-of-life questionnaire. Patient inclusion for the first multicentre study on coronary anomalies in the Netherlands started in 2020 and will continue for at least 3 years with a minimum of 2 years of follow-up. For patients with a right or left coronary artery originating from the pulmonary artery and coronary arteriovenous fistulas a registry is maintained. Results Primary outcomes are: (cardiac) death, myocardial ischaemia attributable to the ACAOS, re-intervention after surgery and intervention after initially conservative treatment. The influence of work-up examinations on treatment choice is also evaluated. Conclusions Structural evidence for the appropriate management of patients with coronary anomalies, especially (interarterial) ACAOS, is lacking. By means of a structured care pathway in a multicentre setting, we aim to provide an evidence-based strategy for the diagnostic evaluation and treatment of this patient group.

Background With the emergence of coronary computed tomography (CT) angiography, anomalous aortic origin of a coronary artery (ANOCOR) is more frequently diagnosed. Fractional flow reserve derived from CT (FFRCT) is a noninvasive functional test providing anatomical and functional evaluation of the overall coronary tree. These unique features of anatomical and functional evaluation derived from CT could help for the management of patients with ANOCOR. We aimed to retrospectively evaluate the physiological and clinical impact of FFRCT analysis in the ANOCOR registry population. Methods and Results The ANOCOR registry included patients with ANOCOR detected during invasive coronary angiography or coronary CT angiography between January 2010 and January 2013, with a planned 5‐year follow‐up. We retrospectively performed FFRCT analysis in patients with coronary CT angiography of adequate quality. Follow‐up was performed with a clinical composite end point (cardiac death, myocardial infarction, and unplanned revascularization). We obtained successful FFRCT analyses and 5‐year clinical follow‐up in 54 patients (average age, 60±13 years). Thirty‐eight (70%) patients had conservative treatment, and 16 (30%) patients had coronary revascularization after coronary CT angiography. The presence of an ANOCOR course was associated with a moderate reduction of FFRCT value from 1.0 at the ostium to 0.90±0.10 downstream the ectopic course and 0.82±0.11 distally. No significant difference in FFRCT values was identified between at‐risk and not at‐risk ANOCOR. After a 5‐year follow‐up, only one unplanned percutaneous revascularization was reported. Conclusions The presence of ANOCOR was associated with a moderate hemodynamic decrease of FFRCT values and associated with a low risk of cardiovascular events after a 5‐year follow‐up in this middle‐aged population.

Full Metal Jacket

Objective: Modern coronary interventional practice can result in coronary vessels that are totally stented. The term “full metal jacket” has been coined to refer to vessels that have an overlapping stent in series along the whole length of the vessel. This poses a serious challenge to surgical revascularization, particularly when a left internal thoracic artery (LITA) to the left anterior descending (LAD) needs to be undertaken. We evaluated the early and midterm results of on-pump coronary artery bypass grafting (CABG) following “stent endarterectomy” for the LAD with LITA to LAD grafting. Methods: During October 2017 to September 2020, 21 patients presented with multi-vessel disease and a totally occluded LAD with a stent full metal jacket. No distal target for LITA grafting was available, despite a viable myocardial territory. The LAD was endarterectomised, removing the column of totally occluded stents with the medial wall of the vessel, leaving the proximal stent in place to avoid competitive flow. Long length anastomosis was then undertaken with the LITA graft. Postoperatively, patients were followed up clinically and by coronary computed tomography (CT) angiography at 6- and 18-month intervals. All patients were discharged on a combination of aspirin and warfarin for three months and then aspirin and clopidogrel for the rest of the first year and then aspirin alone for life. Results: Patients had a mean age of 58.07 ± 2.06 yr. Sixteen (76.2%) were males, 13 (61.9%) patients were diabetics, 18 (85.7%) were hypertensive, 15 (71.4%) were dyslipidemic, six (28.6%) were obese, 11 (52.4%) were smokers, and five (23.8%) had positive family history of ischemic heart disease (IHD). The number of grafts per patient ranged 3-5, with a mean cross-clamp time of 64.71± 8.84 min. There were no postoperative deaths nor MI clinically, by electrocardiogram (ECG) criteria nor by troponin or CK-MB. In-hospital complications included one (4.8%) patient who required re-exploration for bleeding, one (4.8%) developed a superficial wound, and three (14.3%) developed atrial fibrillation (AF), during their hospital stay. Mean hospital stay was 7.71±1.73 days. All patients completed the 6-month follow up showing patent LITA to LAD with coronary CT angiography. One patient was lost to follow up after six months; five patients are awaiting their 18-month CT angiography, while 15 (71.4%) patients have completed their 18-month CT angiography, and all have a patent LITA to LAD. Conclusions: Stent endarterectomy for a totally occluded LAD with a full metal jacket and viable myocardial territory is a safe procedure with good early and midterm results. This technique should be considered in these difficult cases presenting for revascularisation when no other option is available.

Background: Coronary artery disease (CAD) shows a chronic but heterogeneous clinical course. Coronary CT angiography (CTA) allows for the visualization of the entire coronary tree and the detection of early stages of CAD. The aim of this study was to assess short-time changes in non-calcified and mixed plaques and their clinical impact using coronary CTA in a real-world setting.Methods: Between 11/2014 and 07/2019, 6,701 patients had a coronary CTA with a third-generation dual-source CT, of whom 77 patients (57 males, 63.8 ± 10.8 years) with a chronic CAD received clinically indicated follow-up CTA. Non-calcified and mixed plaques were analyzed in 1,211 coronary segments. Patients were divided into groups: stable, progressive, or regressive plaques.Results: Within the follow-up period of 22.3 ± 10.4 months, 44 patients (58%) showed stable plaques, 27 (36%) showed progression, 5 (7%) showed regression. One patient was excluded due to an undetermined CAD course showing both, progressive and regressive plaques. Age did not differ significantly between groups. Patients with plaque regression were predominantly female (80 vs. 20%), whereas patients showing progression were mainly male (85 vs. 15%; p < 0.01 for both). Regression was only observed in patients with mild CAD or one-vessel disease. The follow-up CTA led to changes in patient management in the majority of subjects (n = 50; 66%).Conclusions: Changes in coronary artery plaques can be observed within a short period resulting in an adjustment of the clinical management in the majority of CAD patients. Follow-up coronary CTA renders the non-invasive assessment of plaque development possible and allows for an individualized diagnostics and therapy optimization.

Background: Anomalous aortic origin of the left coronary artery (AAOLCA) confers a rare, but significant, risk of sudden cardiac death (SCD) in children. Surgical intervention is recommended for AAOLCA with an interarterial course, with other subtypes considered benign. We aimed to determine the clinical characteristics and outcomes of AAOLCA in a prospective cohort following a standardized approach. Methods: All patients with AAOLCA <20 years old were prospectively enrolled. Anatomic details were obtained with coronary computerized tomography angiography (CTA). Myocardial functional studies were obtained under provocative stress, including exercise stress test, stress nuclear perfusion imaging, or dobutamine stress cardiac magnetic resonance. Patients were stratified as high-risk if: 1) episode of aborted SCD, 2) interarterial and/or intramural course, or 3) evidence of myocardial ischemia on functional studies. Results: A total of 47 patients (32 male, 68%) with AAOLCA were enrolled, median age 12 [IQR 6.0;15.0] years. Of these, 20 had exertional symptoms (42.5%) and 5 had aborted SCD (10.5%). Thirty-one patients (79%) were classified high-risk, 28% low-risk, and 3 (6%) work-up is ongoing. Of patients with completed work-up, 16/43 (37%) had inducible ischemia and, of these, 2/16 (13%) presented without symptoms and one with aborted SCD as the first symptom. Two patients in our cohort had AAOLCA arising close to the noncoronary sinus, just above the left and noncoronary commissure, resulting in ostial stenosis: one presented with aborted SCD and another with left ventricular dysfunction. To date, 17 patients have undergone repair, median age 10 years [IQR 6.6;15.7]. Median follow-up was 3.9 [IQR 1.3;6.3] years with no significant symptoms and all but 4 patients are cleared from exercise restrictions. Conclusion: AAOLCA may present with diverse anatomic configuration and risk stratification is essential to determine management. AAOLCA from the noncoronary sinus may also present with myocardial ischemia and, thus, be classified as high-risk. A multimodality imaging approach is necessary to adequately risk stratify this population. All patients are alive at last follow-up and the majority free from exercise restriction.

Background Ambulatory management of isolated acute deep vein thrombosis (DVT) is the standard of care in most patient populations, and in clinical practice is mostly initiated in the emergency department (ED). However, patients referred to the ED with suspected DVT often experience unnecessary delays to diagnosis and subsequent long stays to determine appropriate treatment and follow up care. We implemented a DVT ambulatory care pathway that does not include the ED for referred patients with suspected isolated DVT that begins with pre-test risk stratification in the community and subsequent algorithm-based diagnostic work-up, treatment, and follow-up at a tertiary care centre in Montreal Canada. Objective To determine the diagnostic performance of a non-ED based DVT ambulatory care pathway. Methods We determined the prevalence of DVT over a 46 week period between August 2018 and June 2019 among ambulatory patients with suspected isolated DVT who following community-based risk stratification using the modified Well's clinical prediction score were referred for diagnostic work up and treatment using a newly implemented non-ED based DVT ambulatory care pathway. Results Among 122 patients referred by community physicians, 86 (70%) met pre-defined pathway criteria for assessment of suspected DVT. In all, 42 (49%) were referred with an unlikely/low modified Well's score and 44 (51%) with a likely/high score. Overall, the prevalence of DVT was 19.8%, specifically 9.5% in the unlikely/low and 30.2% in the likely/high pretest probability groups, respectively. Conclusion Our results show that the diagnostic performance of a non-ED based acute DVT ambulatory care pathway is in line with literature estimates. The advantage of this pathway is that it offers clear, evidence-based guidance for community physicians to diagnosis and treat patients in an ambulatory setting without using the ED. The approach is likely to result in both healthcare and economic benefits, including increased patient satisfaction and shorter ED stays.

IntroductionCurrent evaluation of patients suspected of a non-ST-elevation acute coronary syndrome (NSTE-ACS) involves the use of algorithms that incorporate clinical information, electrocardiogram (ECG) and high-sensitivity cardiac troponins (hs-troponins). While primarily designed to rule out NSTE-ACS safely, these algorithms can also be used for rule in of NSTE-ACS in some patients. Still, in a substantial number of patients, these algorithms do not provide a conclusive work-up. These patients often present with an atypical clinical profile and low-range positive hs-troponin values without a characteristic rise or fall pattern. They represent a heterogeneous group of patients with various underlying conditions; only a fraction (30%–40%) will eventually be diagnosed with a myocardial infarction. Uncertainty exists about the optimal diagnostic strategy and their management depends on the clinical perspective of the treating physician ranging from direct discharge to admission for invasive coronary angiography. Coronary CT angiography (CCTA) is a non-invasive test that has been shown to be safe, fast and reliable in the evaluation of coronary artery disease. In this study, we will determine the usefulness of CCTA in patients with acute chest pain and low-range positive hs-troponin values.Methods and analysisA prospective, double-blind, observational, multicentre study conducted in the Netherlands. Patients aged 30–80 years presenting to the emergency department with acute chest pain and a suspicion of NSTE-ACS, a normal or non-diagnostic ECG and low-range positive hs-troponins will be scheduled to undergo CCTA. The primary outcome is the diagnostic accuracy of CCTA for the diagnosis of NSTE-ACS at discharge, in terms of sensitivity and negative predictive value.Ethics and disseminationThis study was approved by the Medical Research Ethics Committee of Erasmus Medical Center in Rotterdam, the Netherlands (registration number MEC-2017-506). Written informed consent to participate will be obtained from all participants. This study’s findings will be published in a peer-reviewed journal.Trial registration numberClinicalTrials.gov (NCT03129659).

Abstract Coronary artery fistulas, a rare anomaly, are represented by an abnormal communication between the coronary arteries and other vascular structures or cardiac chambers and, in most cases, are detected incidentally. Regularly, they do not cause important pathological changes, but if the symptoms persist, they need to be treated. The hemodynamic impact depends on the localization and size of the fistulas. Noninvasive imaging techniques, such as magnetic resonance imaging and multislice computed tomography, are widely used for the detection of coronary anomalies. The presence of symptoms (angina, dyspnea) is the primary indication for the surgical or percutaneous closure of the communications; therefore, a systematic follow-up is indicated in all cases. We present four cases of coronary artery fistulas, without important hemodynamic complications, detected by multislice computed tomography coronary angiography.

Congenital Coronary Anomalies

An anomalous right coronary artery arising from the pulmonary artery (ARCAPA) is among the least common form of congenital coronary anomalies, accounted for the incidence of only 0.002% in the general population. Most ARCAPA patients have no symptoms but may develop myocardial ischemia. Surgical correction of the anomaly is recommended to prevent subsequent fatal outcomes. Here, we reported a case of a 2-year-old female child initially hospitalized for diarrhea, but later diagnosed with an ARCAPA through echocardiogram and computed tomography. Surgical reimplantation of the right coronary artery from the pulmonary artery to the ascending aorta was performed. The patient recovered well from the surgery with no postoperative complications. In the follow-up assessments, normal coronary function and myocardial effusion were demonstrated.

Purpose Complex endovascular aortic repair (EVAR) procedures provide a treatment option for patients with aortic aneurysms involving visceral branches. Good technical results and short-term outcomes have been reported. Whether complex EVAR provides acceptable functional outcomes is not clear. The current study aims to describe postoperative functional outcomes in complex EVAR patients—an older and relatively frail patient group. Materials and Methods A single-center retrospective cohort study was performed, using data from a computerized database of consecutive patients who underwent complex EVAR in the Leiden University Medical Center (LUMC, The Netherlands) between July 2013 and September 2020. As of May 2017, patients scheduled for complex EVAR were referred to a geriatric care pathway to determine (Instrumental) Activities of Daily Living ((I)ADL) scores at baseline and, if informed consent was given, after 12 months. For the total patient group, adverse functional performance outcomes were: discharge to a nursing home and 12-month mortality. For the patients included in geriatric follow-up, the additional outcome was the incidence of functional decline (defined by a ≥2 point increase in (I)ADL-score) at 12-month follow-up Results Eighty-two patients underwent complex EVAR, of which 68 (82.9%) were male. Mean age was 73.3 years (SD=6.3). Within 30 days postsurgery, 6 patients (7.3%) died. Mortality within 12 months for the total patient group was 14.6% (n=12). After surgery, no patients had to be discharged to a nursing home. Fifteen patients (18.3%) were discharged to a rehabilitation center. Twenty-three patients gave informed consent and were included in geriatric follow-up. Five patients (21.7%) presented functional decline 12 months postsurgery and 4 patients had died (17.4%) by that time. This means that 39.1% of the patients in the care pathway suffered an adverse outcome. Conclusion To our knowledge, this is the only study that examined functional performance after complex EVAR, using a prospectively maintained database. No patients were newly discharged to a nursing home and functional performance results at 12 months are promising. Future multidisciplinary research should focus on determining which patients are most prone to deterioration of function, so that efforts can be directed toward preventing postoperative functional decline.
