Abstract
BACKGROUND Current evidence suggests that percutaneous coronary intervention for unprotected left main coronary artery disease (LMPCI) in selected patients is a safe alternative to coronary artery bypass grafting. However, real-world long-term survival data is limited. METHODS We analyzed 24,644 patients from the MIG (Melbourne Interventional Group) registry between 2005 and 2020. We compared baseline clinical and procedural characteristics, in-hospital and 30-day outcomes, and long-term survival between unprotected LMPCI and non-LMPCI among patients without ST-segment elevation myocardial infarction, cardiogenic shock, or cardiac arrest. RESULTS Unprotected LMPCI patients (n = 185) were significantly older (mean age 72.0 vs. 64.6 years, p < 0.001), had higher prevalence of impaired ejection fraction (EF <50 %; 27.3 % vs. 14.9 %, p < 0.001) and lower estimated glomerular filtration rate < 60 ml/min/1.73m2 (40.9 % vs. 21.5 %, p < 0.001), and had greater use of intravascular ultrasound (21 % vs. 1 %, p < 0.001) and drug-eluting stents (p < 0.001). LMPCI was associated with longer hospital stay (4 days vs. 2 days, p < 0.001). There was no significant difference in other in-hospital outcomes, 30-day mortality (0.6 % vs. 0.6 %, p = 0.90), and major adverse cardiac events (1.7 % vs. 3 %, p = 0.28). Although the unadjusted Kaplan-Meier survival to 8 years was significantly less with LMPCI compared to non-LMPCI (p < 0.01), LMPCI was not a predictor of long-term survival up to 8 years after Cox regression analysis (HR 0.67, 95 % CI 0.40-1.13, p = 0.13). CONCLUSION In this study, non-emergent unprotected LMPCI was uncommonly performed, and IVUS was underutilized. Despite greater co-morbidities, LMPCI patients had comparable 30-day outcomes to non-LMPCI, and LMPCI was not an independent predictor of long-term mortality.

Abstract
After restoration of coronary perfusion in patients presenting with ST-segment elevation myocardial infarction (STEMI), discrete severe stenotic coronary lesions are not always apparent. There remains ambiguity whether drug-eluting stent (DES) insertion or initial medical management is best practice. We sought to assess short-term clinical outcomes in patients presenting with STEMI without initial stent insertion. Patients who underwent percutaneous coronary intervention for STEMI between 2014 and 2020 were prospectively enrolled and assessed for inclusion. Patients presenting with in-stent restenosis or stent thrombosis, or who did not survive to hospital discharge were excluded. Of 13,871 patients presenting, 456 (3.3%) were treated without initial stenting. These patients were older than those treated with DES (66.1 ± 13.6 vs 62.3 ± 12.4 years, p <0.001), had higher rates of diabetes (23.5% vs 16.0%, p <0.001) and previous revascularization with either percutaneous coronary intervention (14.0% vs 7.3%, p <0.001) or coronary artery bypass graft (3.5% vs 1.8%, p = 0.008). Thirty-day mortality was elevated in patients treated without stenting compared to those receiving DES (4.2% vs 0.9%, p <0.001), as were rates of myocardial infarction (1.3% vs 0.5%, p = 0.026) and major adverse cardiac events (10.5% vs 2.4%, p <0.001). After propensity matching, a trend toward increased mortality remained (4.2% vs 2.0%, p = 0.055). In conclusion, a no-stenting initial strategy, compared with DES insertion, is associated with increased 30-day mortality in those presenting with STEMI without severe stenosis. These data suggest when appropriate, current-generation DES insertion should be undertaken.

Abstract
PURPOSE OF REVIEW Coronary angiography-associated acute ischaemic stroke (CAAIS) is an uncommon event but is associated with significant mortality and morbidity. The incidence of CAAIS has increased with a rise in the volume of coronary angiography (CA) and percutaneous coronary intervention (PCI) performed. Intravenous thrombolysis (IVT) is utilized in the general management of acute ischaemic stroke; however, it is associated with a higher risk of intracranial hemorrhage (ICH). As CA or PCI is performed more often in an aging population or high-risk patients that also carry an increased risk of ICH, it is vital to minimize additional complications from the treatment of CAAIS. This article aims to review the pathophysiological mechanisms for CAAIS, clarify the current evidence regarding IVT use in this setting, and thus assist cardiologists in the management of CAAIS. RECENT FINDINGS The pathophysiology for CAAIS may be different from acute ischaemic stroke in the general population. Embolic phenomena from dislodgement of calcium or other debris during manipulation of instrumentation during CA or PCI are likely mechanisms. This may contribute to altered thrombus composition, which affects the efficacy of IVT as suggested in recent studies. Furthermore, IVT in the management of CAAIS has not been evaluated specifically. The utilization of IVT should be carefully considered in CAAIS given a paucity of evidence demonstrating safety and efficacy in this setting. A multidisciplinary pathway that emphasizes the involvement of cardiologists in the treatment decision-making process would aid in thoughtful risk-benefit evaluation for IVT use in CAAIS and reduce adverse patient outcomes. Future studies to assess the impact of this pathway on CAAIS outcomes would be beneficial.

Abstract
BACKGROUND When patients with prior coronary artery bypass grafting (CABG) undergo percutaneous coronary intervention (PCI), targeting the native vessel is preferred. Studies informing such recommendations are based predominantly on saphenous vein graft (SVG) PCI. There are few data regarding arterial graft intervention, particularly to a radial artery (RA) graft. OBJECTIVES The aim of this study was to report the characteristics of arterial graft stenoses and evaluate the feasibility of RA PCI. METHODS This study included 2,780 consecutive patients with prior CABG undergoing PCI between 2005 and 2018 who were prospectively enrolled in the MIG (Melbourne Interventional Group) registry. Data were stratified by PCI target vessel. RA graft PCI was compared with both native vessel (native PCI) and SVG PCI. Internal mammary graft PCI data were reported. The primary outcome was 3-year mortality. RESULTS Overall, 1,928 patients (69.4%) underwent native PCI, 716 (25.6%) SVG PCI, 86 (3.1%) RA PCI, and 50 (1.8%) internal mammary graft PCI. Compared with SVG PCI, the RA PCI cohort presented earlier after CABG, less frequently had acute coronary syndrome, and more commonly had ostial or distal anastomosis intervention (P < 0.005 for all). Compared with patients who underwent native PCI, those who underwent RA PCI were more likely to have diabetes and peripheral vascular disease (P < 0.001 for both) and to present with non-ST-segment elevation myocardial infarction (P = 0.010). The RA PCI group had no perforations or in-hospital myocardial infarctions, though no significant difference was found in periprocedural outcomes compared with either native or SVG PCI. No differences were found between RA PCI and either native or SVG PCI in 30-day outcomes or 3-year mortality. CONCLUSIONS Presenting and lesion characteristics differed between patients undergoing arterial compared with SVG PCI, implying a varied pathogenesis of graft stenosis. RA PCI appears feasible, safe, and where anatomically suitable, may be a viable alternative to native PCI.

Abstract
Severe coronary artery calcification is one of the greatest challenges in attaining success in percutaneous coronary intervention, limiting acute and long-term results. In many cases, plaque preparation is a critical prerequisite for delivery of devices across calcific stenoses and also to achieve adequate luminal dimensions. Recent advances in intracoronary imaging and adjunctive technologies now allow the operator to select the most appropriate strategy in each individual case. In this review, we will revisit the distinct advantages of a complete assessment of coronary artery calcification with imaging and application of appropriate and contemporary plaque modification technologies in achieving durable results in this complex lesion subset.

Abstract
BACKGROUND The DISRUPT-CAD study series demonstrated feasibility and safety of intravascular lithotripsy (IVL) in selected patients, but applicability across a broad range of clinical scenarios remains unclear. AIMS This study aims to evaluate the procedural and clinical outcomes of IVL in a high-risk real-world cohort, compared to a regulatory approval cohort. METHODS Consecutive patients treated with IVL and percutaneous coronary intervention at our center from May 2016 to April 2020 were included. Comparison was made between those enrolled in the DISRUPT-CAD series of studies to those with calcified lesions but an exclusion criteria. RESULTS Among 177 patients treated with IVL, 142 were excluded from regulatory trials due to acute coronary syndrome presentation (47.2%), left ventricular ejection fraction <40% (22.5%), chronic renal failure (12.0%), or use of mechanical circulatory support (8.5%). This clinical cohort had a higher SYNTAX score (22.6 ± 12.1 vs. 17.4 ± 9.9, p = 0.019), and more treated ACC/AHA C lesions (56.3% vs. 37.1%, p = 0.042). Rates of device success (93.7% vs. 100.0%, p = 0.208), procedural success (96.5% vs. 100.0%, p = 0.585), and minimal lumen area gain (221.2 ± 93.7% vs. 198.6 ± 152.0%, p = 0.807) were similar in both groups. The DISRUPT-CAD cohort had no in-hospital mortality, 30-day major adverse cardiac events (MACE), or 30-day target vessel revascularization (TVR). The clinical cohort had an in-hospital mortality of 4.2%, 30-day MACE of 7.8%, and 30-day TVR of 1.5%. There was no difference in 12-month TVR (2.9% vs. 2.2%; p = 0.825). Twelve-month MACE was higher in the clinical cohort (21.1% vs. 8.6%, p = 0.03). CONCLUSION IVL use remains associated with high clinical efficacy, procedural success, and low complication rates in a real-world population previously excluded from regulatory approving trials.

Abstract
BACKGROUND Percutaneous coronary intervention (PCI) in stable ischaemic heart disease (SIHD) has not been shown to improve prognosis but can alleviate symptoms and improve quality of life. Appropriately selected patients with symptoms refractory to medical therapy therefore stand to benefit, provided safety is proven. METHODS Consecutive patients undergoing PCI for SIHD between 2005-2018 in a prospective registry were included. Yearly comparisons evaluated trends, and a sub-analysis was performed comparing proximal left anterior descending artery (prox-LAD) to other-than-proximal LAD (non-pLAD) PCI. Outcomes included peri-procedural characteristics, in-hospital and 30-day event rates including MACE, and 5-year National Death Index (NDI) linked mortality. RESULTS There were 9,421 procedures included. Over time, patients were increasingly co-morbid and had higher rates of AHA/ACC class B2/C lesions, ostial stenoses, bifurcation lesions, and chronic total occlusions (all p-for-trend ≤0.001). Over 14 years, major bleeding reduced (1.05% in 2005/06 vs 0.29% in 2017/18, p-for-trend <0.001), while other in-hospital and 30-day event rates were stably low. There were only seven (0.07%) in hospital deaths and 5-year mortality was 10.3%. No differences were found in outcomes between patients who underwent prox-LAD compared to non-pLAD PCI. Major independent predictors of NDI linked all-cause mortality included an eGFR <30 mL/min/1.73 m2 (HR 4.06, 95% CI 3.26-5.06), chronic obstructive pulmonary disease (COPD) (HR 2.25, 95% CI 1.89-2.67) and LVEF <30% (HR 2.13, 95% CI 1.57-2.89). CONCLUSIONS Although patient and procedural complexity increased over time, a high degree of procedural success and safety was maintained, including in those undergoing prox-LAD PCI. These real-world data can enhance shared decision making discussions regarding whether PCI should be pursued in patients with symptomatic SIHD refractory to medical therapy.

Abstract
AIMS To describe the utility and safety of intravascular lithotripsy (IVL) in the setting of primary percutaneous coronary intervention (PCI) for ST elevation myocardial infarction (STEMI). METHODS AND RESULTS We performed a retrospective analysis, across six UK sites of all patients in whom IVL was used for coronary calcium modification of the culprit lesion during primary PCI for STEMI. The 72 patients were included. IVL was used in de-novo culprit lesions in 57 (79%) of cases and culprit in-stent restenoses in 11 (15%) of cases. In four cases (6%) it was used in a newly deployed stent when this was under-expanded due to inadequate calcium modification. Of the 30 cases in which intracoronary imaging was available for stent analysis, the average stent expansion was 104%. Intra-procedural stent thrombosis occurred in one case (1%), and no-reflow in three cases (4%). The 30 day MACE rates were 18%. CONCLUSION IVL appears to be feasible and safe for use in the treatment of calcific coronary artery disease in the setting of STEMI.

Abstract
BACKGROUND Increasingly, fractional flow reserve (FFR) is employed to assess coronary artery stenoses although there is limited real world long-term outcome data with a recent report questioning its safety. This study aimed to assess the in-hospital complications and clinical outcomes up to 10 years after FFR-guided revascularisation at a tertiary Australian hospital. METHODS The cohort comprised 274 consecutive patients undergoing FFR from 2010 to 2015 with follow-up to 2020. In-hospital complications and long-term outcomes were compared between patients with FFR≤0.80 and FFR>0.80. Major adverse cardiac events (MACE) comprised cardiac death, myocardial infarction (MI) and target vessel revascularisation (TVR). RESULTS The FFR was ≤0.80 in 166 and >0.80 in 108 patients. Stable coronary disease was present in 95%. Revascularisation was undertaken in 86.7% of the FFR≤0.80 group and in 2.8% of the group with an FFR>0.80. In-hospital adverse events were 3.3% with no pressure wire-related coronary dissection, stroke or death. At median follow-up of 5 years, patients with FFR≤0.80 and FFR>0.80 had a similar rate of cardiac death (2.6% versus 5.0%, p=0.335) and MI (2.6% versus 6.9%, p=0.154). In the FFR>0.80 group, MACE (17.8% v 7.9%; p=0.018) and TVR (12.9% v 5.3%; p=0.033) were significantly higher. CONCLUSION This observational study highlights the safety and long-term effectiveness of FFR-guided coronary revascularisation in patients with predominantly stable disease.

Abstract
BACKGROUND In cardiogenic shock with severe left main coronary artery stenosis (LM), limited information exists on short and longer-term outcomes. We sought to determine the outcomes of unprotected LM PCI in cardiogenic shock. METHODS Excluding patients with previous CABG, consecutive patients undergoing PCI in cardiogenic shock from the Melbourne Intervention Group registry between 2005 and 2013 were analysed. Those post LM PCI were compared to those post non-LM PCI. Patient and procedural data were collected with 30-day and 12-month follow-up. Australian National Death Index linkage was performed for long-term mortality analysis. RESULTS After excluding previous CABG, 18,069 procedures were performed during 1st January 2005 to 30th November 2013, 601 procedures in the setting of cardiogenic shock. Of these, 45 were performed to an isolated LM and 556 to a non-LM. Those with LM PCI were older and more likely to have a baseline left ventricular ejection fraction (LVEF) of <45%. The in-hospital, 30-day, 12-month and long-term mortality to 9 years in cardiogenic shock after LM PCI was 64.4%, 66.7%, 73.3% and 80.0% compared to 36.5%, 36.9%, 40.5% and 46.0%, after non-LM PCI (p < 0.001). On multivariate analysis, LM PCI was a significant independent predictor of long-term mortality (HR1.59, 95%CI 1.00-2.53, p = 0.048). Landmark analysis of survivors to discharge found the long-term mortality of LM PCI approaches 60% compared to 27% for those with non-LM PCI (p = 0.003). CONCLUSION Long-term outcomes after PCI to LM in cardiogenic shock are poor, with much of the excess in mortality occurring early. However, reasonable long-term survival was found beyond the initial high-risk period.

Abstract
The combination of severe coronary disease, significant valvular dysfunction and impaired ventricular function pose patients at a very high procedural risk. In addition, the presence of left ventricular thrombus can complicate ventricular instrumentation increasing embolic risk. Contemporary techniques and devices have now become available to overcome these challenges to reduce risk and allow safer, more efficient procedures. We describe the feasibility of using Impella CP™ with cerebral protection to facilitate complete revascularisation and percutaneous valve replacement in a patient with critical aortic stenosis, severe left ventricular (LV) impairment, LV thrombus and a calcified left main stem disease.

Abstract
Intravascular lithotripsy facilitates percutaneous coronary intervention of lesions with severe calcification by using high-pressure ultrasonic energy. It is the newest adjunctive tool for calcium modification and is showing promise as its users gather more experience and it becomes readily available worldwide. This article reviews intravascular lithotripsy technology, the evidence in the literature, and the advantages and disadvantages compared with other forms of calcium modification, and discusses its role in specific subsets of coronary lesions. It concludes with a discussion about the future direction of research involving this new technology as its role within percutaneous cardiac procedures becomes more defined.

Abstract
BACKGROUND Shorthand is commonplace in clinical notation. While many abbreviations are standard and widely accepted, an increasing number are non-standard and/or unrecognisable. AIM We sought to describe the frequency of inappropriate and ambiguous shorthand in discharge summaries. METHODS Eighty electronic discharge summaries from the four General Medical Units at the Royal Melbourne Hospital were randomly extracted from the hospital's electronic records. Extraction was stratified by the four units and by the four quarters between July 2012 and June 2013. All abbreviations were assigned into one of four categories according to appropriateness: 1. 'Universally accepted and understood even without context'; 2. 'Understood when in context'; 3. 'Understood but inappropriate and/or ambiguous'; and 4. 'Unknown'. These categories were determined by the authors, which included junior and senior medical staff. RESULTS The 80 discharge summaries contained 840 different abbreviations used on 6269 occasions. Of all words, 20.1% were abbreviations. Of the 6269 occasions of shorthand, 6.8% were categorised as 'Understood but inappropriate and/or ambiguous' or 'Unknown' (category 3 or 4), equating to 1.4% of all words, and an average of 5.4 words per discharge summary. CONCLUSION Abbreviations are common in electronic discharge summaries, occurring at a frequency of one in five words. While the majority of shorthand used seems to be appropriate, the use of inappropriate, ambiguous or unknown shorthand is still frequent. This has implications for safe and effective patient care and highlights the need for better awareness and education regarding use of shorthand in clinical notation.

Abstract
Current guidelines recommend performing echocardiography in all patients with Staphylococcus aureus bacteremia (SAB), but patients at very low risk of endocarditis may not benefit from this investigation. This study seeks to identify patients at very low risk of endocarditis. A retrospective single-center consecutive case series of patients with SAB was examined. Microbiological and echocardiographic data were used to identify patients with community onset, prolonged bacteremia, and intracardiac prosthetic devices. The diagnostic performance of these criteria for endocarditis as measured against transesophageal echocardiography (TEE) was calculated. 593 episodes of SAB were examined over a period of 6 years. 10 % were excluded from analysis due to death or discharge less than 48 h after the first positive blood culture or no admission to hospital, leaving 532 episodes for analysis. 64 % of the included episodes were investigated with echocardiography: 39 % with TEE and 26 % with transthoracic echocardiography (TTE) only. 16 % of the episodes investigated with echocardiography were demonstrated to have endocarditis. The rate of endocarditis was higher for episodes undergoing TEE (24 %) than TTE only (5 %). There were no instances of endocarditis amongst the 23 episodes investigated with TEE where none of the three risk factors were present. This group represented 57 % of the nosocomial (non-community-onset) episodes investigated with TEE. Patients with none of the three criteria examined in this study have a very low rate of endocarditis and may fall below the test threshold for echocardiography.

Abstract
PURPOSE The Argus II epiretinal prosthesis has been developed to provide partial restoration of vision to subjects blinded from outer retinal degenerative disease. Participants were surgically implanted with the system in the United States and Europe in a single arm, prospective, multicenter clinical trial. The purpose of this investigation was to determine which factors affect electrical thresholds in order to inform surgical placement of the device. METHODS Electrode-retina and electrode-fovea distances were determined using SD-OCT and fundus photography, respectively. Perceptual threshold to electrical stimulation of electrodes was measured using custom developed software, in which current amplitude was varied until the threshold was found. Full field stimulus light threshold was measured using the Espion D-FST test. Relationships between electrical threshold and these three explanatory variables (electrode-retina distance, electrode-fovea distance, and monocular light threshold) were quantified using regression. RESULTS Regression analysis showed a significant correlation between electrical threshold and electrode-retina distance (R2 = 0.50, P = 0.0002; n = 703 electrodes). 90.3% of electrodes in contact with the macula (n = 207) elicited percepts at charge densities less than 1 mC/cm2/phase. These threshold data also correlated well with ganglion cell density profile (P = 0.03). A weaker, but still significant, inverse correlation was found between light threshold and electrical threshold (R2 < 0.52, P = 0.01). Multivariate modeling indicated that electrode-retina distance and light threshold are highly predictive of electrode threshold (R2 = 0.87; P < 0.0005). CONCLUSIONS Taken together, these results suggest that while light threshold should be used to inform patient selection, macular contact of the array is paramount. TRANSLATIONAL RELEVANCE Reported Argus II clinical study results are in good agreement with prior in vitro and in vivo studies, and support the development of higher-density systems that employ smaller diameter electrodes. (clinicaltrials.gov identifier: NCT00407602).

Abstract
Two cases are reported of delayed diffuse lamellar keratitis after uneventful laser in situ keratomileusis. The first patient presented with an epithelial defect 6 weeks after laser in situ keratomileusis. Three days later the defect was healed but diffuse lamellar keratitis was noted. This was treated with topical dexamethasone and ketorolac with complete resolution of the diffuse lamellar keratitis over 3 weeks. The second patient presented with an epithelial defect and gross diffuse lamellar keratitis 10 weeks after laser in situ keratomileusis. Treatment was with topical dexamethasone and ciprofloxacin with gradual resolution of the diffuse lamellar keratitis. Common to both patients was a background of rosacea, implanted debris with no initial reaction, and epithelial defects leading to diffuse lamellar keratitis. It is suggested that these two cases represent epithelial defect associated corneal infiltration, which resembles classical diffuse lamellar keratitis with the spread of inflammatory cells through a path of least resistance.

Abstract
This paper describes a small-scale survey undertaken with 300 nurses, midwives and health visitors on post-registration courses and registered for the ENB Higher Award. The aim was threefold: first to examine reasons for electing to use particular libraries; second, the relationship between workplace, home, teaching site and choice of library services; and third, the use of library enquiry services. There was a 56% response rate to the postal questionnaire and results indicated that the key factor in selecting a library was availability of resources rather than convenience to home or workplace. The third largest group of respondents worked in community organizations with little or no on-site access to resources and were dependent on access to other libraries. Most who used the library for literature searching needed to seek help in spite of preliminary user education sessions. Similar levels of assistance were needed to locate journals and use the computerized book catalogue. The paper recommends explicit information on strategic entry points, necessity of a broad central collection, integration of information retrieval into post-registration courses, use of self-study packs, better trust/university liaison and recognition of the need for resource transfer from teaching to learning.

Abstract
This paper reports on a survey of user activity in a London teaching hospital with a multidisciplinary health sciences library. Library users were asked to complete a simple survey form on each visit to the library over a week long period. Information was required to help establish a formula for funding. The user survey examined reasons for visiting the library, frequency of visits, length of visit and also asked for comments and suggestions. Finally there is discussion regarding the effectiveness of the survey in terms of the practical framework utilized and of the gains obtained.

Abstract
Pretreatment serum lactate dehydrogenase (LDH) levels were assayed in 288 patients presenting with small-cell lung cancer (SCLC) between 1976 and 1985. Patients were routinely staged by physical examination, chest x-ray, bone, brain, and liver scans, and bone marrow evaluation. Clinical response and survival were assessed following treatment with combination chemotherapy as part of four clinical trials. Patients with extensive disease (ED) presented with a higher incidence (108 of 147, 73%) of abnormally elevated LDH (greater than 193 IU/L) than those (65 of 141, 46%) with limited disease (LD) (P = 2 x 10(-6)). Forty percent of patients had an initial normal LDH level and a higher response rate (89 of 108, 82%; complete response [CR], 47%) than those with elevated values of LDH (119 of 156, 76%; CR, 29%). The CR rate varied inversely with the level of LDH in patients with LD (P = .026) but not in those with ED (P = .300). The median survival time and 1-year and 2-year survival rates for patients with elevated LDH were 39 weeks and 33% and 6%, respectively, whereas for those with a normal LDH level these were 53 weeks and 54% and 16%, respectively. Patients with LD and elevated levels of LDH manifested a higher relative death rate (1.63:1) when compared with patients with LD and LDH in the normal range (P = .0083). The survival of patients with ED did not differ between those with normal and elevated levels of LDH (P = .273). A significant survival advantage persisted for patients with LDH in the normal range following adjustments for extent of disease, performance status (PS), and treatment protocol (P = .044, log-rank analysis). In conclusion, serum LDH appears to be a significant independent pretreatment prognostic factor in patients with SCLC that correlates with stage of disease, response to treatment, and survival.
