BACKGROUND: Refractory ventricular fibrillation or pulseless ventricular tachycardia (rVF/pVT) during out-of-hospital cardiac arrest (OHCA) is associated with poor survival. Double sequential defibrillation (DSED) and vector change (VC) improved survival for rVF/pVT in the DOSE-VF RCT. However, the role of angiography and percutaneous coronary intervention (angiography/PCI) during the trial is unknown. OBJECTIVES: To determine the incidence of ST-elevation (STE) and no ST-elevation (NO-STE) on post-arrest ECG and the use of angiography/PCI in patients with rVF/pVT during the DOSE-VF RCT...

Electrical storm (ES) is a critical and potentially life-threatening cardiac rhythm disorder. It is characterized by the presence of three or more distinct episodes of sustained ventricular tachycardia (VT) or ventricular fibrillation (VF) that necessitate appropriate termination. ES may occur in the setting of acute myocardial infarction or following myocardial reperfusion. An urgent treatment approach is necessary for better outcomes. We represent a case of a 64-year-old patient who presented with sudden chest pain and an episode of palpitations related to non-ST elevation myocardial infarction (NSTEMI), who has undergone percutaneous coronary intervention of the stenotic epicardial artery, but subsequently experienced an ES in the absence of stent thrombosis...

BACKGROUND: General interest and incidence are increasing in wild-type transthyretin amyloidosis (ATTRwt) in recent time. As patient population increases, further knowledge of the management of the frequently encountered interacting cardiac comorbidities is requested to improve treatment of ATTRwt patients. CASE SUMMARY: A 73-year-old male ATTRwt patient presented to the outpatient clinic (Day 0) with dyspnoea, leg swelling, and palpitations. At diagnosis, 3 years prior to presentation, he exhibited only minor signs of ATTRwt...

BACKGROUND: Quantitative flow ratio (QFR) and target-vessel SYNTAX score (tvSS) are novel indices used to assess lesion physiology and morphology in percutaneous coronary intervention (PCI). Their prognostic implication after successful recanalization of coronary chronic total occlusion (CTO) is unknown. OBJECTIVES: To investigate the prognostic value of QFR measured immediately after successful CTO-recanalization in predicting vessel-oriented adverse events, and to compare it with the pre-procedural morphological tvSS...

In addition to the well-known convex ST-segment elevation myocardial infarction (STEMI) pattern associated with acute occlusive myocardial infarction (OMI), there are other cases that are recognized as OMI without fulfilling the established characteristic STEMI criteria. Over one-fourth of the patients initially classified as having non-STEMI can be re-classified as having OMI by recognizing other STEMI equivalent patterns. We report a case of a 79-year-old man with multiple comorbidities who was brought to the ED by paramedics with a two-hour history of ongoing chest pain...

AIMS: Emerging data show that complete revascularization (CR) reduces cardiovascular death and recurrent myocardial infarction in ST-segment elevation myocardial infarction (STEMI). However, the influence of revascularization status on development of arrhythmia in the long-term post-STEMI phase is poorly described. We hypothesized that incomplete revascularization (ICR) compared with CR in STEMI is associated with an increased long-term risk of new-onset arrhythmia. METHODS AND RESULTS: Patients with STEMI treated with primary percutaneous coronary intervention (PPCI) at Copenhagen University Hospital, Rigshospitalet, Denmark, with CR or ICR were identified via the Eastern Danish Heart registry from 2009 to 2016...

Early coronary revascularization is a first choice therapeutic strategy in the case of acute myocardial infarction (MI). Despite an early coronary angioplasty, however, in some cases, there is a lower efficacy of revascularization, with less favourable clinical outcome in the short and long terms. Various elements participate in the distant prognosis after primary coronary angioplasty (PCI). Among the clinical risk factors that predispose to a recurrence of ischaemic cardiovascular events are advanced age, diabetes mellitus, chronic renal failure, peripheral vascular disease, atrial fibrillation and the multiplicity of cardiovascular risk factors, which identify a higher baseline risk profile...

Left ventricular end-diastolic pressure (LVEDP) is an important hemodynamic marker of left ventricular performance and affects coronary perfusion. We evaluated the association of LVEDP with patient outcomes after elective or urgent percutaneous coronary intervention (PCI). We included n = 49,600 patients undergoing elective or urgent PCI. Patients were divided according to LVEDP tertile for descriptive analysis. The primary end point was in-hospital mortality. A recursive partitioning tree model for mortality was built to guide decision-making in patients with high LVEDP undergoing nonemergent PCI...

BACKGROUND: Trials have shown that for patients on oral anticoagulants (OAC), a short course of dual antiplatelet therapy (DAPT) with OAC reduces post-percutaneous coronary intervention (PCI) bleeding without increasing ischemic events. Adoption of this strategy has been variable. We evaluated the impact of an institutional quality improvement (QI) initiative to reduce the use of triple therapy (TT, OAC + DAPT) and improve discharge communication post-PCI. METHODS: A hospital-wide QI initiative was developed to minimize time on TT post-PCI...

Anomalous origin of the right coronary artery (ARCA) represents <3% of congenital coronary anomalies, while the subaortic membrane represents 6.5% of congenital heart anomalies. Symptomatic co-occurrence of ARCA and subaortic membrane in an adult is rare. A 68-year-old man developed a non-ST-elevation myocardial infarction necessitating percutaneous coronary intervention (PCI) four years prior to presentation at our hospital. In the years after his PCI, he developed progressive exertional breathlessness...

Although the incidence of acute coronary syndrome (ACS) has increased over the decades, the overall prognosis has improved with newer stents, tailored medication, and better intervention techniques. Atrial fibrillation (AF) and ventricular arrhythmia at the time of ACS diagnosis are known indicators of a poor acute prognosis. However, there is a lack of data regarding the long-term arrhythmic impact of ventricular tachyarrhythmia (VA) on mortality in ACS patients. This study sought to elucidate the impact of tachyarrhythmia on mortality during long-term follow-up in patients with a history of ACS...

Background: Catheter ablation of the ventricular substrate can reduce ventricular tachycardia (VT) recurrence and mortality in an electrical storm (ES). However, identification and specific treatment of plausible triggers is mandatory and may lead to the resolution of ES. Objective: This case presentation seeks to exemplify how pulmonary vein isolation (PVI) may represent a tailored treatment of ES in cases of ventricular substrate, which only becomes arrhythmogenic during high-rate episodes of paroxysmal atrial fibrillation (PAF)...

BACKGROUND: Intracoronary epinephrine has been effectively used in treating refractory no-reflow, but there is a dearth of data on its use as a first-line drug in normotensive patients in comparison to the widely used adenosine. METHODS: In this open-labeled randomized clinical trial, 201 patients with no-reflow were randomized 1:1 into intracoronary epinephrine as the treatment group and intracoronary adenosine as the control group and followed for 1 month. The primary end points were improvement in coronary flow, as assessed by TIMI (Thrombolysis in Myocardial Infarction) flow, frame counts, and myocardial blush...

Patients with ST-elevation myocardial infarction (STEMI) due to coronary occlusion require immediate restoration of epicardial and microvascular blood flow. A potentially new reperfusion method is the use of ultrasound and microbubbles, also called sonothrombolysis. The oscillation and collapse of intravenously administered microbubbles upon exposure to high mechanical index (MI) ultrasound pulses results in thrombus dissolution and stimulates nitric oxide-mediated increases in tissue perfusion. The aim of this study was to assess feasibility of sonothrombolysis in the ambulance for STEMI patients...

BACKGROUND: Myocardial infarction is the most frequent cause for out-of-hospital cardiac arrest (OHCA) in adults. Patients with ST-segment elevations (STE) following return of spontaneous circulation (ROSC) are regularly admitted to the catheterisation laboratory for urgent coronary angiography. Whether patients without obvious STE (NSTE) should receive coronary angiography as part of a standardised diagnostic work-up following OHCA is still debated. METHODS: We analysed a cohort of 517 subsequent OHCA patients admitted at our institution who received a standardised diagnostic work-up including coronary angiography and therapeutic hypothermia...
