Spontaneous coronary artery dissection (SCAD) was underdiagnosed and poorly understood for decades. It is increasingly recognized as an important cause of myocardial infarction (MI) in women. We aimed to assess the natural history SCAD, which has not been adequately explored. performed a multicentre, prospective, observational study patients with non-atherosclerotic SCAD presenting acutely from 22 centres North America. Institutional ethics approval patient consents were obtained. recorded...
Background: Patients post-coronary artery bypass graft (CABG) can re-present with acute coronary syndrome (ACS); however, culprit lesion identification, as well revascularization, is often challenging. Furthermore, the impact of revascularization in this patient group relatively unknown. Objectives: The purpose our study was to evaluate efficacy percutaneous intervention (PCI) patients previous CABG surgery presenting ACS. Methods: Using data from Manitoba Center for Health Policy, we...
Rotational atherectomy (RA) for heavily calcified lesions is essential improved stent delivery and expansion. In tortuous vessels it often difficult to advance the burr without rotation possible injury endothelium of healthy vessel. The GuideLiner catheter, a child in mother has recently been used allow increased support stents through vessels. We report novel use an RA requiring guide support.
Background The Zwolle Risk Score was designed to identify the risk of complications in patients with ST-segment‒elevation myocardial infarction (STEMI) following percutaneous coronary intervention (PCI). Its utility PCI STEMI treated thrombolysis is unknown. objective evaluate safety using triage PCI, including receiving thrombolysis. Methods and Results Patients aged ≥18 years primary or after were included. A protocol developed, high-risk those ≥4 triaged cardiac intensive care unit....
Abstract Objectives The aims of this single‐center retrospective study were to characterize and determine predictors 30‐day survival in a cohort patients requiring venoarterial extracorporeal membrane oxygenation (VA‐ECMO) supported cardiopulmonary resuscitation (E‐CPR) the cardiac catheterization laboratory (CCL) for arrest (CA) or refractory cardiogenic shock (CS). Background While safety CCL has improved, periprocedural mortality from CA remains high. application VA‐ECMO is an emerging...
Real-world data regarding the efficacy and safety of coronary intravascular lithotripsy (IVL) are lacking. We conducted a study 50 consecutive patients (64 lesions) who underwent IVL. 3 suffered in-hospital mortality unrelated to IVL; there was no other occurrence MACE up 30 days. Angiographic success nearly universal (98% with residual stenosis <50%, 96% TIMI flow) complication rare, including among undergoing IVL for in-stent restenosis or left main artery lesions. In high-risk real-world...
We aim to describe the in-hospital outcomes of first reported Canadian cohort patients with cardiogenic shock and acute myocardial infarction (MI) due total occlusion left main coronary artery, treated initial percutaneous intervention (PCI). Acute thromboses were identified (N = 8) from a retrospective consecutive high risk PCI 56) performed at our institution 2004-2009. The mean age was 62.3 ± 13.2 years, 6 (75%) male patients. Successful in all patients, thrombectomy utilized 4 (50%),...
Objective. Out of hospital cardiac arrest (OHCA) patients are a critically ill patient population with high mortality. Combining mild therapeutic hypothermia (MTH) early coronary intervention may improve outcomes in this population. The aim study was to evaluate predictors mortality OHCA undergoing MTH and without catheterization. Design. A retrospective cohort who underwent catheterization (MTH + C) NC) between 2006 2011 analyzed at single tertiary care centre. Predictors in-hospital...
Intravascular lithotripsy (IVL) is associated with excellent angiographic and short-term results in patients calcified lesions requiring percutaneous coronary intervention. We conducted a 1-year follow up of retrospective cohort 47 (61 lesions) who underwent IVL. The primary outcome was target vessel revascularization (TVR) at from index procedure. Four percent required TVR within 1 year; 96% IVL remained free repeat intervention on the same vessel. One patient suffered myocardial...
Guide catheter induced dissection of coronary arteries is an uncommon, but serious complication angioplasty. Treatment can include emergent artery bypass grafting to the affected vessel or percutaneous intervention including wiring true lumen and exclusion stenting flap prevent further propagation. Detailed descriptions have been published techniques intentional passage guide wires into false reentry with chronic total occlusions. We present unusual case what appeared be successful...
As a result of the COVID-19 pandemic first wave, reductions in ST-elevation myocardial infarction (STEMI) invasive care, ranging from 23% to 76%, have been reported various countries. Whether this change had any impact on coronary angiography (CA) volume or mechanical support device use for STEMI and post-STEMI complications Canada is unknown. We administered Canada-wide survey all cardiac catheterization laboratory directors, seeking CA performed during period March 1 2020 May 31, (pandemic...
The proportion of individuals >80 years age constitute an increasing patients who present with ST-segment elevation myocardial infarction (STEMI). objective this study is to evaluate in-hospital outcomes and 1-year survival very elderly STEMI undergo primary percutaneous coronary intervention (pPCI). Between 2009 2015, (very patients) presenting at a single tertiary Canadian care center were included in the study. A random sample 100 aged 65 69 over same time period selected as control...
Several large studies have demonstrated a correlation between cold weather and incidence of myocardial infarction; however there is no clear consensus on daily temperature, lag time snowfall ST segments elevation infarction (STEMI). Winnipeg one the coldest major cities (>500 000 population) in world, as such, good model to assess risk environmental temperature STEMI. A retrospective audit all patients was done with STEMI within city (July 1, 2008 December 31, 2013). Inclusion criteria: >18...
Left ventricular apical thrombus is a known complication following an anterior ST-elevation myocardial infarction. Although left ventriculography may suggest in the presence of filling defect, additional imaging with echocardiography and/or cardiac magnetic resonance strongly recommended to further characterize post
