A multivariate and retrospective analysis of the impact of intra-aortic balloon counterpulsation in Open-Heart surgery.

Background The use of intraaortic balloon pump (IABP) effectively reduces left ventricular afterload and significantly increases coronary perfusion pressure by raising aortic diastolic pressure. This study examined the short and medium-term outcomes of 22,540 adult cardiac surgical patients requiring an IABP. Methods From 2009 to 2018, 1114 patients (4.

Is preoperative IABP insertion significantly reducing postoperative complication in augmented high-risk coronary artery bypass grafting patients?

Background: The aim of this study was to determine whether pre-operative intra-aortic balloon pump (IABP) insertion improves surgical outcomes in high-risk coronary artery bypass grafting (CABG) patients.

Methods: Patients with a EuroSCORE II greater than 1.2% who underwent CABG from 2009 to 2016 were included in the study, while those who utilized intra-operative or post-operative IABP were excluded.

Stroke prevention strategies for cardiac surgery: a systematic review and meta-analysis of randomized controlled trials.

Background: Stroke is a much-feared complication of cardiac surgery, but existing literature on preventive strategies is fragmented. Hence, a systematic review and meta-analysis of stroke prevention strategies for cardiac surgery was conducted.

Methods: An electronic literature search was conducted to retrieve randomized controlled trials (RCTs) investigating perioperative interventions for cardiac surgery, with stroke as an outcome.

Routine preoperative screening computed tomography of the thorax for cardiac surgery.

Introduction: This study aimed to evaluate the role of screening computed tomography (CT) of the thorax in cardiac surgery by analysing the presence of CT aortic calcifications in association with changes in operative strategy and postoperative stroke, and the CT features of emphysema with development of pneumonia.

Methods: All patients who underwent cardiac surgery from January 2013 to October 2017 by a single surgeon were retrospectively studied. Patients who underwent screening CT thorax before cardiac surgery (CT group) were compared to those who did not (no CT group).

N-Acetylcysteine's Renoprotective Effect in Cardiac Surgery: A Systematic Review and Meta-Analysis.

Objective: To examine N-acetylcysteine's (NAC's) renoprotective effect in adult cardiac surgeryMethods: PubMed, Ovid Medline, and Embase were searched for randomized controlled trials published between January 1990 and May 2021 that investigated the effect of NAC in preventing acute kidney injury (AKI) in patients undergoing cardiac surgery. The inclusion criterion was studies that assessed the effect of NAC in comparison to placebo by measuring the incidence of AKI.

Results: Overall meta-analytic estimates of all 10 included trials showed that NAC did not have a significant effect (odds ratio [OR]: 0.

Minimally invasive tricuspid valve surgery and concomitant MAZE procedure with closure of LA appendage through an ASD.

Utilization of the ASD as a gateway to reach the left heart in tricuspid valve surgery may facilitate the use of a mini right thoracotomy and single atriotomy approach, avoiding the need for bi-atrial incisions and/or median sternotomy.

Optimal vortex formation time index in mitral valve stenosis.

Left ventricular vortex formation time (VFT) is a novel dimensionless index of flow propagation during left ventricular diastole, which has been demonstrated to be useful in heart failure and cardiomyopathy. In mitral stenosis (MS), flow propagation in the LV may be suboptimal. We studied VFT in varying degrees of MS.

Massive pulmonary embolism in a patient with nephrotic syndrome and single lung.

We present a novel case of a patient with nephrotic syndrome and previous left pneumonectomy who had a massive pulmonary embolism of his remnant right pulmonary artery. He underwent surgical embolectomy and veno-arterial extracorporeal membrane oxygenation (ECMO). Early embolectomy using retrograde pulmonary perfusion and post-operative ECMO helped the patient survive this catastrophic event.

Meta-analysis of the benefit of beta-blockers for the reduction of isolated atrial fibrillation incidence after cardiac surgery.

Objectives: Postoperative atrial fibrillation (POAF) is a common problem of cardiac surgery. Beta-blockers are recognized as effective prophylactic agents available for POAF management. To better understand its effect on isolated atrial fibrillation after cardiac surgery, a meta-analysis was conducted.

Sleep apnoea and cardiovascular outcomes after coronary artery bypass grafting.

Objective: Patients with advanced coronary artery disease are referred for coronary artery bypass grafting (CABG) and it remains unknown if sleep apnoea is a risk marker. We evaluated the association between sleep apnoea and major adverse cardiac and cerebrovascular events (MACCE) in patients undergoing non-emergent CABG.

Methods: This was a prospective cohort study conducted between November 2013 and December 2018.

An Asian Perspective on Gender Differences in Clinical Outcomes and Echocardiographic Profiles of Patients With Medically Managed Severe Aortic Stenosis.

Background: Gender differences in valvular heart disease are increasingly recognised. A prior study has suggested better surgical outcomes in women with symptomatic aortic stenosis (AS). We investigate gender differences in medically managed severe AS.
