Atrial fibrillation (AF) is the most common cardiac arrhythmia in clinical practice, which can induce cardiac dysfunction and strokes, causing a substantial socioeconomic burden. Patients with AF undergoing cardiac surgery have an increased risk of ventricular dysfunction, comorbidities, and mortality. Eradicating AF during cardiac surgery could decrease the number of adverse cardiovascular eve...

INTRODUCTION Truncus arteriosus with intact ventricular septum is a rare and unique variant of persistent truncus arteriosus (PTA) which usually presents with central cyanosis and congestive heart failure in neonate and early infancy. Associated cardiac and non-cardiac anomalies may affect morbidity and mortality of these patients. CASE PRESENTATION We describe clinical presentation, echocard...

BACKGROUND Quality improvement initiatives in cardiac surgery largely rely on risk prediction models. Most often, these models include isolated populations and describe isolated end-points. However, with the changing clinical profile of the cardiac surgical patients, mixed populations models are required to accurately represent the majority of the surgical population. Also, composite model end-...

background: postoperative pulmonary dysfunction is one of the most frequent complications after cardiac surgery and it is believed to result from the use of cardiopulmonary bypass (cpb). in this study, we investigated the effect of low tidal volume ventilation during cpb on postoperative gas exchange and lung mechanics. methods: this prospective randomized study included 100 patients undergoing...

BACKGROUND Cardiac arrest is a lethal complication of Nuss repair of pectus excavatum which is strongly related to heart or big vessels injury. A rare case developed cardiac arrest without direct cardiac injury during Nuss procedure is presented in this article. CASE PRESENTATION In July 2015, a previously healthy 18-year-old man undergoing Nuss repair for pectus excavatum developed cardiac a...

hydatid disease commonly involves liver but in rare cases, it can involve cardiac structures. a 75-yr-old farmer from parsabad-moghan, northwestern iran was presented to the emergency room of tehran imam khomeini hospital, tehran, iran with dyspnea and without chest pain in 2014. a lesion compatible with hydatid cyst was found in echocardiography and confirmed by serology and mri. surgical trea...

Clinically significant pericardial effusion is an uncommon complication after cardiac surgery. Pericardiocentesis can be performed either through a mini-sternotomy or under echocardiography guidance. Echocardiography guidance is a relatively safe procedure and it avoids the need for another general anaesthetic. However, in this post cardiac surgical patient echocardiography guided pericardiocen...

Background. Surgical correction of mitral regurgitation (MR) can lead to postoperative low cardiac output state. We aimed to assess the acute hemodynamic changes after percutaneous MitraClip therapy (a unique model without influence of factors linked to surgical procedure) in patients with functional MR without the influence of general anaesthesia. Methods. We studied invasive hemodynamic param...

Current open-heart procedures requiring the use of a medial sternotomy and a heart-lung machine can potentially be performed by entering the heart through the cardiac wall. A new procedure in cardiac surgery involves introducing an ablation tool through the appendage of the left atrium. This method, intended for the treatment of atrial fibrillation, septal defect repair and valve replacement, p...
