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.

Telecardiographic measurements for device migration: A useful tool for follow-up.

Objective: Pump thrombosis in left ventricular assist device (LVAD) patients is an important cause of mortality and morbidity. Inflow cannula migration is a predisposing factor for pump thrombosis. Telecardiographic measurements can be used to follow up apical cannula deviation.

Neutrophil-to-lymphocyte ratio for early renal failure under extracorporeal membrane oxygenation support for postcardiotomy shock.

Background: This study aims to investigate the relationship between the neutrophil-to-lymphocyte ratio and renal injury in patients under extracorporeal membrane oxygenation support for postcardiotomy shock.

Methods: Between January 2007 and July 2018, a total of 119 patients (38 males, 81 females; mean age 54.4±13.

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.

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.
