Nanto’s technique for changing a PTCA balloon catheter over a regular-length guide wire
Nanto’s technique for changing a percutaneous transluminal coronary angioplasty (PTCA) balloon catheter over a regular-length guide wire is demonstrated in this vidoe on youtube: http://www.youtube.com/watch?v=mjEjbSNL4IY (unfortunately the description audio [..]
Risk of acute kidney injury less with higher time interval between angiography and CABG
There is an inverse relation between the time to cardiac surgery after angiography and acute kidney injury. Mehta RH and associates [Relationship of the Time Interval Between Cardiac [..]
Ventricular septal defect (VSD)
Swiss cheese ventricular septal defects Multiple muscular ventricular septal defects (VSD) are also called ‘swiss cheese’ VSD. Swiss cheese VSDs are difficult to close surgically. It is difficult [..]
Chronic total occulusion (CTO) an independent predictor of ventricular arrhythmias
Chronic total occulusion (CTO) has been identified as an independent predictor of ventricular arrhythmias in the VACTO Primary Study [Nombela-Franco L et al. Ventricular Arrhythmias Among Implantable Cardioverter [..]
Late and very late stent thrombosis with drug eluting stents
Late and very late stent thrombosis with drug eluting stents still continue to be our concern. Fresh data from the jCypher registry is available from Kimura T and [..]
T-stenting and small protrusion (TAP stenting) in coronary bifurcations
T-stenting and small protrusion technique (TAP-Stenting) is used to enhance side branch ostial coverage. It is an intentional protrusion of side branch stent within the main branch during [..]
Lutembacher syndrome: combination of atrial septal defect with mitral stenosis
The original description of Lutembacher syndrome was as a combination of atrial septal defect with mitral stenosis [Lutembacher R. De la sténose mitrale avec communication interauriculaire. Archives des [..]
Lower very late stent thrombosis with everolimus eluting stents (EES)
Though drug eluting stents have a much lower incidence of restenosis after percutaneous coronary intervention, late stent thrombosis and very late stent thrombosis occurring beyond one year after [..]
Coronary angiography prior to surgery for valvular heart disease
Coronary angiography prior to surgery for valvular heart disease is considered for those forty years and above if there are no coronary risk factors and for those thirty [..]
FFR to assess need for a side branch stent
Fractional flow reserve (FFR) estimation using the Doppler wire is useful in assessing the need for a side branch stent in bifurcation disease. Usually a stent is considered [..]
