RESUMO

IgG4-related disease (IgG4-RD) is a new clinical entity characterized by lymphoplasmacytic lesions rich in IgG4-positive plasma cells. Myocardial involvement is extremely rare and not a typical cardiovascular manifestation of IgG4-RD. We report a rare case of IgG4-RD-associated myocardial mass causing severe aortic incompetence, successfully treated with surgery and corticosteroids. (Level of Difficulty: Intermediate.).

RESUMO

Uncontrolled arterial hypertension is a major global health issue. Catheter-based renal denervation has shown to lower blood pressure in sham-controlled trials and represents a device-based, complementary treatment option for hypertension. In this situation assessment, the authors, who are practicing experts in hypertension, nephrology, general practice and cardiology in the Republic of Ireland, discuss the current evidence base for the BP-lowering efficacy and safety of catheter-based renal denervation with different modalities. Although important questions remain regarding the identification of responders, and long-term efficacy and safety of the intervention, renal denervation has the potential to provide much-needed help to address hypertension and its adverse consequences. The therapeutic approach needs to be multidisciplinary and personalised to take into account the perspective of patients and healthcare professionals in a shared decision-making process.

RESUMO

Radial access during primary percutaneous coronary intervention is associated with reduced mortality and major bleeding compared with femoral access and is the recommended access site. Nevertheless, failure to secure radial access may necessitate crossover to femoral access. This study aimed to identify the associations with crossover from radial to femoral access in all comers with ST-elevation myocardial infarction and to compare the clinical outcomes with those patients who did not require crossover. From 2016 to 2021, a total of 1,202 patients presented to our institute with ST-elevation myocardial infarction. Associations, clinical outcomes, and independent predictors of crossover from radial to femoral access were identified. From 1,202 patients, radial access was used in 1,138 patients (94.7%) and crossover to femoral access occurred in 64 patients (5.3%). Patients who required crossover to femoral access had higher rates of access site complications and longer length of stay in the hospital. Inpatient mortality was higher in the group requiring a crossover. This study identified 3 independent predictors of crossover from radial to femoral access in primary percutaneous coronary intervention: cardiogenic shock, cardiac arrest before arrival at the catheterization laboratory, and previous coronary artery bypass grafting. Biochemical infarct size and peak creatinine was also found to be higher in those requiring crossover. In conclusion, crossover in this study portended an increased rate of access site complications, greatly prolonged length of stay, and a significantly higher risk of death.

RESUMO

AIMS: Dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) remains the standard of care. CYP2C19 genetic polymorphisms cause variable clopidogrel bioactivation. Increased function (CYP2C19*17) allele carriers (rapid metabolizers [RM] or ultrarapid metabolizers [UM]) are clopidogrel hyper-responders, hence are more susceptible to clopidogrel-related bleeding. Since current guidelines recommend against routine genotyping following PCI, data on the clinical utility of CYP2C19*17 genotype guided strategy are sparce. Our study provides real-world data on the 12-month follow-up of CYP2C19 genotyping in patients post-PCI. METHODS: This is a cohort study within an Irish population receiving 12-month DAPT following PCI. It identifies the prevalence of CYP2C19 polymorphisms within an Irish population and describes the ischaemic and bleeding outcomes after 12 months of DAPT. RESULTS: A total of 129 patients were included with the following CYP2C19 polymorphism prevalence: 30.2% hyper-responders (26.4% RM [1*/17*], 3.9% UM [17*/17*]) and 28.7% poor-responders (22.5% IM [1*/2*], 3.9% IM [2*/17*], 2.3% PM [2*/2*]). A total of 53 and 76 patients received clopidogrel and ticagrelor, respectively. At 12 months, total bleeding incidence within the clopidogrel group was positively correlated with CYP2C19 activity: IM/PM (0.0%), NM (15.0%) and RM/UM (25.0%). The positive relationship showed a moderate association that was statistically significant: rτ = 0.28, P = 0.035. CONCLUSIONS: The prevalence of CYP2C19 polymorphisms in Ireland is 58.9% (30.2% CYP2C19*17, 28.7% CYP2C19*2) with an approximately one in three chance of being a clopidogrel hyper-responder. Positive correlation between bleeding and increasing CYP2C19 activity within the clopidogrel group (n = 53) suggests possible clinical utility of a genotype-guided strategy identifying high bleeding risk with clopidogrel in CYP2C19*17 carriers, but further studies are required.

RESUMO

Total ischaemic time in ST-elevation myocardial infarction (STEMI) has been shown to be a predictor of mortality. The aim of this study was to assess the total ischaemic time of STEMIs in an Irish primary percutaneous coronary intervention (pPCI) centre. A single-centre prospective observational study was conducted of all STEMIs referred for pPCI from October 2017 until January 2019. There were 213 patients with a mean age 63.9 years (range 29-96 years). The mean ischaemic time was 387 ± 451.7 mins. The mean time before call for help (patient delay) was 207.02 ± 396.8 mins, comprising the majority of total ischaemic time. Following diagnostic electrocardiogram (ECG), 46.5% of patients had ECG-to-wire cross under 90 mins as per guidelines; 73.9% were within 120 mins and 93.4% were within 180 mins. Increasing age correlated with longer patient delay (Pearson's r=0.2181, p=0.0066). Women exhibited longer ischaemic time compared with men (508.96 vs. 363.33 mins, respectively, p=0.03515), driven by a longer time from first medical contact (FMC) to ECG (104 vs. 34 mins, p=0.0021). The majority of total ischaemic time is due to patient delay, and this increases as age increases. Women had longer ischaemic time compared with men and longer wait from FMC until diagnostic ECG. This study suggests that improved awareness for patients and healthcare staff will be paramount in reducing ischaemic time.

RESUMO

BACKGROUND: The clinical significance of peak troponin levels following ST-elevation myocardial infarction (STEMI) has not been definitively established. The purpose of this study was to examine the relationship between peak high-sensitivity cardiac troponin T (hs-cTnT) and all-cause mortality at 30 days and 1 year, and left ventricular ejection fraction (LVEF) in STEMI. METHODS: A single-centre retrospective observational study was conducted of all patients with STEMI between January 2015 and December 2017. Demographics and clinical data were obtained through electronic patient records. Standard Bayesian statistics were employed for analysis. RESULTS: During the study period, 568 patients presented with STEMI. The mean age was 63.6±12 years and 76.4% were men. Of these, 535 (94.2%) underwent primary percutaneous coronary intervention, 12 (2.1%) underwent urgent coronary artery bypass and 21 (3.7%) were treated medically. Mean peak hs-cTnT levels were significantly higher in those who died within 30 days compared with those who survived (12 238 ng/L vs 4657 ng/L, respectively; p=0.004). Peak hs-cTnT levels were also significantly higher in those who died within 1 year compared with those who survived (10 319 ng/L vs 4622 ng/L, respectively; p=0.003). The left anterior descending artery was associated with the highest hs-cTnT and was the most common culprit in those who died at 1 year. An inverse relationship was demonstrated between peak hs-cTnT and LVEF (Pearson's R=0.379; p<0.00001). CONCLUSIONS: In STEMI, those who died at 30 days and 1 year had significantly higher peak troponin levels than those who survived. Peak troponin is also inversely proportional to LVEF with higher troponins associated with lower LVEF.

RESUMO

BACKGROUND: Extrinsic warming of contrast media (CM) to 37 °C before angiographic procedures is performed to improve bolus kinetics and avoid potential adverse effects. Extrinsically warmed CM readily loses temperature after removal from the warming cabinet, but the extent of its cooling has not been previously investigated. PURPOSE: To assess temperature loss of extrinsically warmed CM in tubing of traditional angiographic manifolds during simulated angiography. MATERIAL AND METHODS: In total, 35 scheduled diagnostic angiographic procedures were observed in a hospital setting. Relevant time points of CM use during the procedures were recorded. The shortest, median, and longest procedures were then simulated in the experimental laboratory to measure CM temperatures at specific times at three locations along the tubing system. RESULTS: The angiographic procedures lasted 7.0-26.6 min (median = 11.7 min), with the total duration dependent primarily on the time from contrast being removed from the warming cabinet to the commencement of imaging. During the simulated procedures, consistent patterns of temperature loss were observed. By the last simulated angiographic run, injected CM temperature decreased by 7.4-16.4 °C, depending on procedure length. Most of the heat loss occurred in the tubing between the CM bottle and coronary control syringe. CONCLUSION: During angiographic procedures, prewarmed CM loses its temperature rapidly with the duration of exposure to ambient room temperature. If no additional measures are employed to maintain its temperature outside of the warming cabinet, extrinsic warming has limited impact on injected CM temperature.

RESUMO

OBJECTIVE: Advancement in healthcare provision has led to increasing octogenarian ST elevation myocardial infarction (STEMI) presentation to hospital for early revascularisation therapies. Limited literature to date exists to suggest octogenarian STEMI population; with majority of trials excluding these age group patients. Due to an ageing population, we expect increasing rates of STEMI in the octogenarian and nonagenarian population in the future. This study seeks to identify the outcomes of patients over the age of 80 presenting with STEMI and determine the factors associated with better or worse outcome. PATIENTS AND METHODS: This study is a single-centre retrospective observational study involving patients' age 80 or older presenting with STEMI between January 2014 and December 2019. Patient data were collected by chart review and analysis of the local STEMI database. Standard Bayesian statistics were employed for analysis. RESULTS: 1301 patients presented with STEMI during this period. 159/1301 (12.2%) were 80 years or older that fulfilled STEMI criteria, 35/159 (22.1%) were medically managed. 107/124 (86.29%) had angiographic evidence of acute total or partial thrombotic occlusion, and 97/107 were treated with primary percutaneous coronary intervention (PPCI). The activation ECG most commonly exhibited an anterior STEMI, while inferior STEMI ECGs had the strongest positive predictive value. PPCI group had a 30-day mortality rate of 20% (p=0.07) and 1-year mortality was 22.4%. Highest mortality was observed with cardiogenic shock, low ejection fraction, higher high sensitivity cardiac troponin T and creatinine at presentation. Conservatively managed patients had significant higher mortality rate (48% vs 22.4%, p=0.005) at 1 year. CONCLUSION: Patients over the age of 80 who present with STEMI and undergo PPCI have a significantly lower mortality rate at 1 year. These patients have a 77.6% survival at 1 year, with 92.4% likelihood of discharge to home (without need for long-term nursing home care). Cardiogenic shock in this group was associated with a 1-year mortality of 87.5%. Despite the advanced age, we suggest favourable outcomes described in the absence of patients presenting with cardiogenic shock.

RESUMO

A 75-year-old woman with a history of intracranial haemorrhage, atrial fibrillation and coronary artery bypass graft underwent elective left atrial appendage occlusion (LAAO) for stroke prevention. The procedure was successful, however on the third postoperative day, she presented with a lymph leak at the right femoral venous access site. She was admitted for conservative management of the lymph leak with immobility and intravenous fluids. Her inpatient stay was complicated by a right lower limb deep vein thrombosis (DVT), left middle cerebral artery territory ischaemic stroke, pulmonary emboli (PEs) and a splenic infarction. The mechanism of the systemic emboli was that of paradoxical emboli from the DVT passing through an interatrial septal defect created as part of the LAAO procedure, a previously unreported complication of LAAO. She was managed with 6 months of low-dose oral anticoagulation for treatment of DVT and PE and has made a full neurological recovery.

RESUMO

BACKGROUND: With an increasing prevalence of coronary heart disease, secondary prevention forms a major cornerstone of management. A dedicated nurse-led clinic for patients post percutaneous coronary intervention (PCI) offers a great opportunity to address risk factors in order to reduce cardiovascular events. PURPOSE: To determine the impact of a nurse-led clinic follow up of patients post PCI in relation to the 30 day mortality rate and re-admission, and patient satisfaction. Risk factor assessment, compliance with dual antiplatelet therapy (DAPT), and interventions at the clinic visit were also assessed. METHODS: A retrospective review of parameters recorded at clinic appointments from January 2015-December 2017. The data of patients were examined for baseline characteristics, risk factor assessment, and interventions at the clinic visit. Thirty day mortality and re-admission rates and patient satisfaction were major outcomes. RESULTS: 1325 individual patient records were retrospectively reviewed in our clinic. Mean age was 64 and 78% were males. The indications for PCI were STEMI (22.7%), NSTEMI (21.9%), and unstable and stable angina (43.1%). 5 patients (0.4%) died and 132 patients (10%) were re-admitted within 30 days after the follow-up visit. However, only 24 (1.8%) of the re-admissions were due to cardiac reasons. At the clinic appointment, 852 (64.3%) patients had non-pharmacological intervention and 473 (35.7%) patients had a pharmacological intervention. 712 (53.7%) patients had LDL-C above target and their statin therapy was amended accordingly. CONCLUSION: Nurse-led PCI clinics provide satisfactory assessment and management of risk factors achieving high patient satisfaction rates without increased risk of poor outcomes.

RESUMO

Introduction: Atherosclerotic coronary artery disease, in particular acute myocardial infarction (AMI), is a leading cause of morbidity and mortality globally. Percutaneous coronary intervention (PCI) is the mainstay of treatment for obstructive coronary artery disease and AMI through the restoration of TIMI III flow. Despite good macrovascular flow, the myocardium can remain hypoperfusion due to poor microvascular perfusion, and this is referred to as 'no-reflow'. Various treatments have been studied with variable success in both prevention and treatment of no-reflow. Areas covered: This review outlines the cutting-edge diagnostic investigations which have been explored in no-reflow, allowing a deeper understanding of mechanism and microvascular pathological processes involved in its genesis. These include utility of novel MRI techniques and perfusion echo in conjunction with traditional approaches. Detailed review has been undertaken of both pharmacological and non-pharmacological techniques to prevent and manage microvascular dysfunction associated with no-reflow. Particular attention was paid to the evolution and successes of various mechanical protection devices. Expert opinion: Most promising innovations in the diagnosis and management of no-reflow are evaluated, and future outlook is explored. Emerging advances in acute coronary syndrome have their findings applied a role in modifying the pathophysiology of no-reflow.

RESUMO

Purpose: We sought to assess the safety of performing diagnostic radial access coronary angiography with uninterrupted anticoagulation on patients receiving direct oral anticoagulant therapy. Background: Direct oral anticoagulants have become a popular choice for the prevention of thromboembolism. Risk factors for thromboembolism are common among cardiovascular conditions and indications for direct oral anticoagulant therapy as well as coronary angiography often overlap in patients. It has been hypothesised that uninterrupted direct oral anticoagulant therapy would increase haemorrhagic and access site complications, however data in this area is limited. Methods: This was a prospective observational analysis of 49 patients undergoing elective diagnostic coronary angiography while receiving uninterrupted anticoagulation with direct oral anticoagulants. This population was compared with a control group of 49 unselected patients presenting to the cardiology service for elective diagnostic coronary angiography. Continuous variables were analysed using the independent samples t-test and categorical variables using Pearson's χ2 test. Results: The mean duration of radial compression for the control group was 235.8±62.8 min and for the uninterrupted direct oral anticoagulant group was 258.4±56.5 min. There was no significant difference in mean duration of radial compression (p=0.07; 95% CI=-1.4 to 46.5). There was also no difference in the complication rate between the two groups (p=1). Conclusions: We observed similar complication rates and radial artery compression time postangiography in both groups. This small prospective observational study suggests that uninterrupted continuation of direct oral anticoagulants during coronary angiography is safe. Larger randomised control studies in this area would be beneficial.

RESUMO

Transcatheter aortic valve implantation (TAVI) is the treatment of choice in patients with symptomatic severe aortic stenosis who are either inoperable or at high risk for conventional surgical aortic valve replacement. Recent data have also shown favourable outcomes in patients deemed to be at intermediate operative risk, which expands the application of this novel technology. Despite its success, TAVI has been associated with rare life-threatening complications. Of these, aortic annular rupture is considered to be the most devastating. Advances in pre-procedural screening and patient selection have reduced the incidence of annular rupture. When this complication occurs, early recognition and prompt management are essential. This article is intended to provide a comprehensive review of the predictors, management and clinical outcomes of aortic annular rupture.

RESUMO

AIMS: In 2017, Kiemeneij published a paper on distal trans-radial artery access for coronary angiography in 62 patients. This paper proposed several advantages to this method. Since this paper was published, several other papers have been published describing this technique, with less than 200 cases in total described. We performed a non randomized control study of left distal trans-radial access in patients undergoing coronary angiography in our center. METHODS: We prospectively identified patients presenting for coronary angiography to our center for enrolment in this study. We recruited 94 patients (47 ldTRA, 47 age and sex matched controls). Pre-defined endpoints for the study were as follows: time until radial compression device (RCD) removal, procedural time, radiation dose, fluoroscopy time, and contrast dose. RESULTS: Patient and procedural characteristics did not differ significantly between the two groups. With regard to our primary endpoint, patients undergoing ldTRA required, on average, 69 min less time until removal of the RCD (167.8 ± 30 vs 236.6 ± 63.9 min, P < 0.0001). Procedural length did not vary between groups (28.95 ± 5.89 vs 29.76 ± 8.16 min, P = 0.5824). Similarly, there was no statistically significant difference in radiation dose area product (5032.66 ± 2740 vs 4826 ± 2796 Gy/cm2 , P = 0.7191), contrast dose (82.93 ± 23 vs 92.1 ± 33 mL, P = 0.1215), and fluoroscopy time between the two groups (5.41 ± 3.42 vs 4.82 ± 2.97 min, P = 0.3742). CONCLUSIONS: Our study confirms that ldTRA is a feasible technique for diagnostic coronary angiography in a modern cardiac catheterization laboratory. It results in decreased post-procedure radial artery compression time without increasing procedural time or radiation dose.

RESUMO

Purpose: In this study, we sought to prospectively analyse the management and long term outcomes associated with revascularisation of left main stem disease via percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) in our centre. Methods: This prospective study enrolled all patients with unprotected left main stem disease undergoing revascularisation from January 2013 to June 2014. Baseline characteristics, hospital presentation and hospital stay length were collected. Patients were followed up at 1, 2 and 3 years. Primary outcomes of Major Adverse Cardiovascular and Cerebrovascular Events (MACCE) were defined as death, Q wave myocardial infarction, stroke, repeat revascularisation and readmission within 30 days. Results: 56 patients with significant left main stem coronary artery disease were identified from the clinical registry. 27 patients underwent PCI (median age 67.7) and 29 CABG (median age 68.6). PCI patients had a higher surgical risk as measured by mean euroSCORE (4.95±5.8 vs 3.11±3.85). At 3 years, total MACCE occurred in 29.6% of the PCI cohort and 27.5% of the CABG cohort. Death occurred in three patients in the PCI group within the first 6 months. Death occurred in one patient in the CABG group over 2 years postprocedure. Two patients in the CABG cohort presented with Transient Ischemic Attacks (TIAs) at 2-year follow-up. At 3 years, revascularisation occurred in three patients in the PCI cohort. There were no revascularisation events in the CABG cohort. Conclusions: PCI with modern drug eluting stents is a reasonable treatment option for unprotected left main stem disease in a non surgical centre.

RESUMO

AIM: The GuideLiner (GL) is a widely used catheter primarily in complex percutaneous coronary intervention (PCI). Deep seating of the GL and distal stent placement may be facilitated by the anchor-balloon technique (ABT). METHODS: We aimed to prospectively analyze procedural details, technical success, complications and in-hospital outcome in patients who underwent PCI using the GL catheter and the ABT. RESULTS: A total of 118 patients underwent PCI with the aid of the GL and ABT. Procedure success rate was 95% (112/118) and only seven patients (5.9%) encountered complications. ABT was indicated and successfully used in 29 patients (25%). CONCLUSION: GL and ABT successfully aided stent delivery in unfavorable and heavily calcified lesions which otherwise may have been considered unsuitable for PCI.

RESUMO

An 87-year-old woman presented to the emergency department with a 2-week history of progressively worsening shortness of breath, fever and generalised myalgia. She underwent a transcatheter Portico aortic valve implantation for severe symptomatic aortic stenosis 3 months prior to this presentation. Examination revealed a temperature of 40°C and a systolic murmur in the aortic area. Inflammatory markers were elevated, and blood cultures were positive for methicillin-sensitive Staphylococcus aureus A possible diagnosis of infective endocarditis was made as one major and one minor criterion in the modified Duke criteria were fulfilled. Subsequent transoesophageal echocardiography (TOE) demonstrated vegetation attached to the prosthetic valve stent frame at the level of the left ventricular outflow tract. She was started on a prolonged course of intravenous antibiotics, and follow-up TOE, 4 weeks later, confirmed resolution of the vegetation. She was discharged home after prolonged hospital stay.
