Peripheral venoarterial extracorporeal membrane oxygenation in combination with intra-aortic balloon counterpulsation in patients with cardiovascular compromise.

Objectives: Patients with profound cardiovascular compromise have poor prognosis despite inotropic and intra-aortic balloon pump (IABP) support. Peripheral venoarterial extracorporeal membrane oxygenation (V-A ECMO) offers these patients temporary support as a bridge to various options including the 'bridge to recovery'.

Methods: We studied the outcomes of 135 patients who underwent peripheral V-A ECMO and concomitant IABP implantation in our hospital from 2007 to 2012 for various clinical indications.

Transcatheter aortic valve replacement: current developments, ongoing issues, future outlook.

Since the first clinical implantation in 2002, transcatheter aortic valve implantation or transcatheter aortic valve replacement (TAVR) has become an established therapy in the treatment of symptomatic severe aortic stenosis in patients deemed too high risk for surgical aortic valve replacement. With over 50,000 implants performed in more than 40 countries, a large amount of clinical data have emerged in this rapidly growing field. Careful patient selection, systematic risk stratification, optimal valve sizing, meticulous procedural techniques, and complications management are all important elements to achieve good outcomes.

Use of antiplatelet therapy after percutaneous coronary intervention with bare-metal stents and different types of drug-eluting stents.

Dual antiplatelet therapy (DAPT) with a thienopyridine and aspirin has been the standard of care post coronary stent implantation. DAPT has been shown to reduce the risk of stent thrombosis (ST) and complications of myocardial infarction and death after placement of a drug-eluting stent (DES) and bare-metal stent (BMS). This article reviews the available clinical efficacy and safety data of antiplatelet therapies.

Door-to-balloon time in primary percutaneous coronary intervention predicts degree of myocardial necrosis as measured using cardiac biomarkers.

Reduced door-to-balloon time in primary percutaneous coronary intervention for the treatment of ST-elevation myocardial infarction has been associated with lower cardiac mortality rates. However, it remains unclear whether door-to-balloon time is predominantly a surrogate for overall peri-myocardial infarction care and is not independently predictive of outcomes, particularly when differences in door-to-balloon time have narrowed and previous studies have contained myocardial infarction-selection bias.We analyzed 179 consecutive patients who presented emergently at our cardiac catheterization laboratory with ST-elevation myocardial infarction within 12 hours of symptom onset and who underwent primary percutaneous coronary intervention within 3 hours of presentation.

Long-term clinical benefit of sirolimus-eluting stents compared to bare metal stents in the treatment of saphenous vein graft disease.

Objective: The purpose of this study was to evaluate the efficacy of sirolimus-eluting stents (SES) in the treatment of saphenous vein graft (SVG) disease.

Background: Percutaneous coronary intervention (PCI) of SVG lesions with bare metal stents (BMS) is associated with frequent in-stent restenosis, progression of disease in nonstented SVG segments, and suboptimal clinical outcomes. While SES have been shown to reduce restenosis rates in various native lesion subsets, the long-term clinical impact of SES use in SVG lesions is less clear.

Adult patients with Eisenmenger syndrome report flying safely on commercial airlines.

Background: Despite fears of compromised oxygen delivery in patients with Eisenmenger syndrome during flight on commercial aircraft, a clinical study has shown no adverse effects, and many patients travel frequently.

Methods: The air travel history over the past decade of 53 patients with Eisenmenger syndrome and 48 acyanotic patients was obtained. Patients listed all flights and destinations, and any major adverse event or symptoms, including, specifically, headache, palpitations, oedema or need for supplemental oxygen.
