coronary artery anomalies are rare, with their incidence varying from 1 to 5%. angiography is a commonly used modality for the assessment of coronary artery anomalies. based on previous reports, a majority of coronary artery anomalies are of origin or distribution, with separate ostia of the left anterior descending artery and left circumflex artery. coronary artery anomalies may cause myocardi...

iatrogenic coronary artery dissection during coronary angiography with or without rupture is a rare but feared complication . we herein report a case of iatrogenic left main coronary artery dissection in a 49-year-old female. admitted to our hospital with a recent history of severe hypotension, she develpled apnea during angiography. she was intubated  and resuscitated with an epinephrine infus...

In the 1970s and early 1980s, randomized trials comparing coronary bypass surgery with medical therapy emphasized the indications for coronary revascularization. In these trials and database studies, the major benefit of surgery over medical therapy upon survival was among 'sicker' patients, characterized by the severity of ischaemia, the extent of coronary disease and the presence of left vent...

BACKGROUND Various methods have been suggested to prevent hemodynamic instability caused by propofol and adverse effects caused by etomidate induction. The current study evaluated hemodynamic effects of propofol-ketamine mixture in comparison to etomidate-midazolam mixture during anesthesia induction. OBJECTIVES The aim of this study was to evaluate the hemodynamic effects of etomidate-midazo...

Impella 2.5 is a temporary left ventricular assist device that is being increasingly used in high risk Percutaneous Coronary intervention (PCI). It reduces the cardiac workload and provides assistance to myocardium and vital organs in states of severe left ventricular dysfunction and cardiogenic shock. We report the first case of successful percutaneous coronary stenting performed in a high ris...

background: systolic blood pressure recovery (rsbp) is of prognostic value for predicting the survival and co-morbidity rate in patients with coronary artery disease (cad). this study investigated the association between rsbp and exercise indices after complete cardiac rehabilitation program (cr) in a population-based sample of patients undergoing coronary artery bypass grafting (cabg). methods...

the present study was undertaken to compare the in hospital results of coronary artery bypass graft (cabg) with (on pump) or without (off pump) cardiopulmonary bypass (cpb). data were collected on all first-time isolated cabgs with saphenous vein and/or artery grafts at shahid madani hospital in tabriz-iran, between 2006 and 2009. age and clinical profile were marched between on pump and off pu...

To the Editor:—We read with great interest the research article by Fox et al. on genetic variation within defined regions of the NPPA/NPPB and NPR3 natriuretic peptide system genes as predictors for ventricular dysfunction after coronary artery bypass graft surgery. What concerns us as clinicians is the relation between those biomarkers and postoperative outcome, which can facilitate the preope...

It is of value to determine the amount of viable myocardial tissue in patients suffering from chronic coronary artery disease and ventricular dysfunction. Having the capability of evaluating both myocardial perfusion and function, simultaneously, myocardial scanning by ECG-Gated is an appropriate method for this purpose. The aim of this study was to compare the results of myocardial perfu...
