His bundle pacing (HBP) synchronizes atrio-ventricular and intraventricular delays. We observed the relationship between the level of atrio-ventricular block, ventricles synchrony, diastolic function improvement in a patient with moderate systolic disorders and diastolic dysfunction after myocardial infarction. HBP may be useful to treat conduction disorders and prevent further systolic and diastolic dysfunction. We present the case of a 92-year-old man in a very good general psychophysical status, treated with percutaneous coronary intervention of circumferential branch of left coronary artery angioplasty due to myocardial infarction, regional contractility disorders of left ventricle with ejection fraction (LVEF) 45%, and observed long PR interval with paroxysmal second degree atrioventricular conduction block. A successful implantation of a permanent HBP lead in the postinfarction period was performed. The His bundle capture restored AV synchrony and diminished diastolic disorders. Our case demonstrates that atrioventricular conduction disorders in the course of myocardial infarction may be corrected by HBP.

Percutaneous Coronary

Primary percutaneous coronary intervention (PPCI) is recommended by the European Society of Cardiology (ESC) treatment guidelines as the preferred treatment for ST-elevation acute myocardial infarction (STEMI) whenever it is available within 90–120 minutes of the first medical contact. A survey conducted in 2008 in 51 ESC countries found that the annual incidence of hospital admissions for acute myocardial infarction is around 1,900 patients per million population, with an incidence of STEMI of about 800 per million. It showed that STEMI patients’ access to reperfusion therapy and the use of PPCI or thrombolysis (TL) vary considerably between countries. Northern, western and central Europe already have well-developed PPCI services, offering PPCI to 60–90 % of all STEMI patients. Southern Europe and the Balkans are still predominantly using TL. Where this is the case, a higher proportion of patients are left without any reperfusion treatment. The survey concluded that a nationwide PPCI strategy results in more patients being offered reperfusion therapy. To address the inequalities in STEMI patients’ access to life-saving PPCI, and to support the implementation of the ESC STEMI treatment guidelines in Europe, the Stent for Life (SFL) Initiative was launched jointly by the European Association of Percutaneous Cardiovascular Interventions (EAPCI) and EuroPCR in 2008. National cardiac societies from Bulgaria, France, Greece, Serbia, Spain and Turkey signed the SFL Declaration at the ESC Congress in Barcelona in 2009. The aim of the SFL Initiative is to improve the delivery of, and STEMI patients’ access to, life-saving PPCI and thereby reduce mortality and morbidity. Currently, 10 national cardiac societies support the SFL Initiative in their respective countries. SFL national action programmes have been developed and are being implemented in several countries. The formation of regional PPCI networks involving emergency medical services, non-percutaneous coronary intervention hospitals and PPCI centres is considered to be a critical success factor in implementing PPCI services effectively. This article describes examples of how SFL countries are progressing in implementing their national programmes, thus increasing PPCI penetration in Europe.

Bifurcation Lesions

Provisional T-stenting with stenting of the main branch and optional side branch (SB) stenting in the case of significant SB occlusion with thrombolysis in myocardial infarction (TIMI) flow <3 is the strategy chosen nowadays by most interventionalists for treating simple bifurcation lesions. Percutaneous coronary intervention (PCI) of complex true bifurcation lesions remains, however, the subject of debate: treatment of complex bifurcation lesions requires more time than treatment of simple bifurcations and can lead to significantly higher rates of restenosis, target lesion revascularisation and myocardial infarction. Current bifurcation techniques often fail to ensure continuous stent coverage of the SB ostium and of the two bifurcation branches without a simultaneous increase in the rate of malapposed struts. Stent struts left unapposed in the lumen disturb blood flow and are increasingly recognised as increasing the risk of stent thrombosis and focal in-stent restenosis, limiting the success of stent procedures in these lesions. New technology and dedicated designs may, in the near future, overcome such limitations of conventional two-stent bifurcation strategies.

St Elevation

This article reviews optimum therapies for the management of ST-elevation myocardial infarction (STEMI) with primary percutaneous coronary intervention (PCI). Optimum anti-thrombotic therapy includes aspirin, bivalirudin and the new anti-platelet agents prasugrel or ticagrelor. Stent thrombosis (ST) has been a major concern but can be reduced by achieving optimal stent deployment, use of prasugrel or ticagrelor, selective use of drug-eluting stents (DES) and use of new generation DES. Large thrombus burden is often associated poor outcomes. Patients with moderate to large thrombus should be managed with aspiration thrombectomy and patients with giant thrombus should be treated with glycoprotein IIb/IIIa inhibitors and may require rheolytic thrombectomy. The great majority of STEMI patients presenting at non-PCI hospitals can best be managed with transfer for primary PCI even with substantial delays. A small group of patients who present very early, who are at high clinical risk and have long delays to PCI, may best be treated with a pharmaco-invasive strategy.
