Comparative StudyMinimally invasive aortic valve replacement (AVR) compared to standard AVR.
Minimally invasive cardiac surgery has been developed to offer patients the benefits of open heart operations with decreased pain and limited skin incision. A limited superior median sternotomy has been shown to provide a good exposure for aortic valve replacement (AVR) and good results. In this study we report the results of minimally invasive AVR compared to standard sternotomy AVR performed in the same period. ⋯ The limited superior median sternotomy provides good exposure to the left ventricular outflow tract, aortic valve, ascending aorta, and even to the mitral valve through the roof of the left atrium. Therefore it seems to be suitable for all kinds of aortic valve operations. Besides less pain, shorter skin incision, shorter respiratory support time and lower blood loss, it has more advantages as opening and closure of the sternum is faster; decreasing infection and disruption of the sternum, and finally decreasing the time required for hospitalization and recovery.

The outcomes of patients requiring emergent surgical or endovascular intervention during transvenous lead extraction (TLE) have not been well characterized. ⋯ Major vascular injury or cardiac perforation requiring emergent surgical or endovascular intervention during TLE is uncommon but carries significant in-hospital mortality. Despite high mortality, nearly two-thirds of these patients were rescued with immediate response and surgical or endovascular intervention.

Comparative StudyCardiovascular magnetic resonance of scar and ischemia burden early after acute ST elevation and non-ST elevation myocardial infarction.
The acute coronary syndrome diagnosis includes different classifications of myocardial infarction, which have been shown to differ in their pathology, as well as their early and late prognosis. These differences may relate to the underlying extent of infarction and/or residual myocardial ischemia. The study aim was to compare scar and ischemia mass between acute non-ST elevation myocardial infarction (NSTEMI), ST-elevation MI with Q-wave formation (Q-STEMI) and ST-elevation MI without Q-wave formation (Non-Q STEMI) in-vivo, using cardiovascular magnetic resonance (CMR). ⋯ Prior to revascularisation, the ratio of scar to ischemia differs between NSTEMI, Non-Q STEMI and Q-STEMI, whilst the combined scar and ischemia mass is similar between these three types of MI. These results provide in-vivo confirmation of the diverse pathophysiology of different types of acute myocardial infarction and may explain their divergent early and late prognosis.
