This state results in increased mortality and morbidity following cardiac surgery. A better understanding of the associated risk factors will guide the surgical team in patient management.

Pressure-dimension index: A novel "morphologic-functional" index of right ventricle that predicts short-term survival after left ventricular assist device implantation.

Background: Right ventricular failure (RVF) after left ventricular assist device (LVAD) implantation is a major cause of postoperative morbidity and mortality. Despite the availability of multiple imaging parameters, none of these parameters had adequate predictive accuracy for post-LVAD RVF.

Aim: To study whether right ventricular pressure-dimension index (PDI), which is a novel echocardiographic index that combines both morphologic and functional aspects of the right ventricle, is predictive of post-LVAD RVF and survival.

Usefulness of right ventricular contraction pressure index to predict short-term mortality and right heart failure in patients who underwent continuous-flow left ventricular assist device implantation.

Background: Right ventricular stroke work index is a useful but invasively measured parameter that can be used to predict right heart failure following continuous-flow left ventricular assist device implantation. Right ventricular contraction pressure index is a novel parameter that was developed to measure right ventricular stroke work index with echocardiography. We aimed to investigate the clinical usefulness of right ventricular contraction pressure index to predict short-term mortality and right heart failure in patients who underwent continuous-flow left ventricular assist device implantation.

Urban legend or real fact: Coronary artery size varies with demographics.

Objective: This study aimed to determine the relationship between the diameter of coronary artery stents and age, gender, diabetes mellitus (DM), left ventricular ejection fraction (LVEF), renal dysfunction, and the clinical presentation of myocardial ischemia in the cohort of patients with implanted stents in coronary arteries with severe stenotic lesions.

Methods: This study included 2256 patients (mean age, 59.3±10.

A case of a large Chiari network mimicking a right atrial thrombus.

The Chiari network is described as a reticulated network of fibers connected to the Eustachian valve identified as the embryological remnant of the right valve of the sinus venosus. It is an incidental finding without any significant pathophysiological consequences. However, the presence of the Chiari network in the right atrium obliges the physician to differentiate from other right atrial pathologies.

Stent versus bypass: The reasons and risk factors for early readmission to hospital after myocardial revascularization.

Objective: Though 30-day rates of readmission for coronary artery bypass graft (CABG) surgery and percutaneous coronary intervention (PCI) remain high, readmission rates and associated risk factors have not been well examined. The purpose of the present study was to determine the risk factors for and rates of readmission and to compare two revascularization methods on that basis.

Methods: The study included 2664 consecutive patients who underwent coronary revascularization either with CABG surgery or PCI.

The Effect of Left Ventricular Assist Device Implantation on Serum Albumin, Total Protein and Body Mass: A Short-Term, Longitudinal Follow-Up Study.

Background: Cardiac cachexia and low serum albumin levels are poor prognostic signs in advanced heart failure, while overweight patients or patients who gain weight after treatment have more favourable outcomes. Weight gain following LVAD implantation is common, while the dynamic changes in body mass or serum proteins have not been studied adequately. Our aim was to study short-term changes in serum albumin, total protein and body weight following LVAD implantation and to compare these changes with heart failure patients treated medically.

Long term outcomes of surgical revascularization for isolated left main coronary artery stenosis: a single-center surveillance study.

Objective: The objective of this study was to retrospectively analyze the clinical course and postoperative long-term survival of patients diagnosed with isolated left main coronary artery (LMCA) stenosis after surgical revascularization.

Methods: A total of 38 patients (27 males, 11 females) who were diagnosed with isolated LMCA stenosis and underwent surgical revascularization were enrolled in the study. Isolated LMCA stenosis was classified into 2 groups: ostial stenosis and nonostial stenosis.

Preoperative risk factors for in-hospital mortality and validity of the Glasgow aneurysm score and Hardman index in patients with ruptured abdominal aortic aneurysm.

The aim of this study is to evaluate the validity of the Glasgow aneurysm score (GAS) and Hardman index in patients operated on because of ruptured abdominal aortic aneurysm (rAAA), and determining preoperative risk factors that affect in-hospital mortality. One hundred one patients operated on to repair a rAAA within the last 10 years were included. The GAS and Hardman index were calculated for each patient separately.

Emergency management for critical left main coronary artery stenosis.

Background: Increased experience and improvements in technology seem to have encouraged the use of percutaneous interventions for left main coronary artery (LMCA) occlusions. There is no consensus, however, and the data are inadequate on whether surgery or percutaneous procedures should be the intervention of choice for critical occlusions.

Methods: From January 2002 to December 2006, 108 patients with unprotected LMCA stenosis >80% were treated at our center.

Coronary artery bypass graft operations can be performed safely in obese patients.

Objectives: Obesity is a major public health problem with an increasing prevalence. Although coronary artery bypass grafting (CABG) operations are now performed with low morbidity and mortality rates, obesity is still assumed to be an important risk factor for morbidity and mortality at these operations but there is no precise approach to define it as a risk factor. The aim of this study is to evaluate the effects of obesity on the clinical outcome of the CABG operations.
