Transradial versus transfemoral approach for percutaneous coronary intervention in cardiogenic shock: A radial-first centre experience and meta-analysis of published studies

SummaryBackgroundThe transradial approach for percutaneous coronary intervention (PCI) is associated with a better outcome in myocardial infarction (MI), but patients with cardiogenic shock (CS) were excluded from most trials.AimsTo compare outcomes of PCI for MI-related CS via the transradial versus transfemoral approach.MethodsA prospective cohort of 101 consecutive patients admitted for PCI for MI-related CS were treated via the transradial (n=74) or transfemoral (n=27) approach. Cox proportional hazards models adjusted for prespecified variables and a propensity score for approach were used to compare mortality, death/MI/stroke and bleeding between the two groups. A complementary meta-analysis of six studies was also performed.ResultsPatients in the transradial group were younger (P=0.039), more often male (P=0.002) and had lower GRACE and CRUSADE scores (P=0.003 and 0.001, respectively) and rates of cardiac arrest before PCI (P=0.009) and mechanical ventilation (P=0.006). Rates of PCI success were similar. At a mean follow-up of 756 days, death occurred in 40 (54.1%) patients in the transradial group versus 22 (81.5%) in the transfemoral group (adjusted hazard ratio [HR]: 0.49, 95% confidence interval [CI] 0.28–0.84; P=0.012). The transradial approach was associated with reduced rates of death/MI/stroke (adjusted HR: 0.53, 95%CI: 0.31–0.91; P=0.02) and major bleeding (adjusted HR: 0.34, 95%CI: 0.13–0.87; P=0.02). The meta-analysis confirmed the benefit of transradial access in terms of mortality (relative risk [RR]: 0.63, 95%CI: 0.58–0.68) and major bleeding (RR: 0.43, 95%CI: 0.32–0.59).ConclusionThe transradial approach in the setting of PCI for ischaemic CS is associated with a dramatic reduction in mortality, ischaemic and bleeding events, and should be preferred to the transfemoral approach in radial expert centres

Coronary-Pulmonary Fistulas Involving All Three Major Coronary Arteries Co-Existing With Myocardial Infarction

We report the case of a man who presented with acute anterior myocardial infarction and in whom the coronary angiogram showed tight stenosis of the left anterior descending coronary artery and the right coronary artery associated with substantial coronary-pulmonary fistulas involving all three major coronary arteries. We discuss the possible links between coronary artery fistulas and myocardial infarction

Atrial septostomy in cardiogenic shock related to H1N1 infection

The circulatory assistance, mainly the extra-corporeal membrane oxygenation (ECMO) restores hemodynamics and serves to limit the myocardial work, in order to avoid left ventricular dilation, high end-diastolic pressures, increased wall stress, subendocardial ischemia and consequently worsening pulmonary congestion and edema. In patients with large myocardial damage, sometimes an additional unloading of the left ventricle is warranted. We report a case of percutaneous blade and balloon atrial septostomy (BAS) as an add-on to the circulatory assistance to unload the left heart in a cardiogenic shock related to H1N1 infection

Iatrogenic bidirectional dissection of the right coronary artery and the ascending aorta: the worst nightmare for an interventional cardiologist

Although rare, iatrogenic aortocoronary dissection is one of the complications most dreaded by the interventional cardiologist. If not managed promptly, it can have redoubted and serious consequences. Herein, we present the case of a 70 year-old woman who was treated by stenting of the second segment of the right coronary artery (RCA) for recurrent angina but, unfortunately, the procedure was complicated by anterograde dissection of the RCA with a simultaneous retrograde propagation to the proximal part of the ascending aorta. Successful stenting of the entry point was able to recuperate the RCA and to limit the retrograde propagation to the ascending aorta, but there was an extension of the dissection to the aortic valve leaflets resulting in a massive aortic insufficiency. Therefore, an isolated surgical aortic valve replacement was performed

Left main coronary stenting in a non surgical octogenarian population: a possible approach

Coronary artery bypass grafting is conventionally considered the standard treatment for significant left main coronary artery (LMCA) disease. The management of LMCA disease in octogenarians is however still debated. The aim of this study was to appreciate the safety and effectiveness of percutaneous coronary intervention (PCI) for LMCA disease in octogenarians who were denied for surgical revascularization. The study included 70 consecutive patients 6580 years of age who had undergone PCI for the treatment of LMCA and who were primary denied by our center's heart team for surgical revascularization. Mean age was 83.4\ub12.6 years. Mean Euroscore was 21.1\ub116.7 and mean Syntax score was 28.6\ub18.7. Overall in-hospital mortality was 11%. Mean follow-up time was 30.5\ub124.2 months. Overall mortality at the end of follow-up was 28%. Cardiac death was found in 18 patients and 2 patients died from terminal renal insufficiency. One patient (2%) presented with a new STEMI, 7 (11.3%) with a new non-STEMI, 13 (21%) with heart failure, and 2 (3.2%) had minor hemorrhage. There was a percutaneous target vessel revascularization in 6 (10%) patients. During follow-up, the total major adverse cerebral and cardiovascular event (MACCE including death, non-fatal acute myocardial infarction (AMI), target lesion revascularization (TLR), or stroke) was 27.4%. Stent implantation was relatively safely applied for the treatment of LMCA disease in octogenarians who were refused for surgery and who represented a high risk population. Despite a non-negligible rate of MACCE, the clinical long term outcome seems correct for this specific population with heavy basal status
