Mortality Rates in Staged Bilateral Total Knee Arthroplasty: A Systematic Review and Meta-Analysis.

This systematic review and meta-analysis aimed to assess the mortality rates of staged bilateral total knee arthroplasty (staBTKA) procedures. This systematic review followed the suggestions and recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020. We performed a primary search in the PubMed, EBSCO, Scopus, Web of Science via Clarivate, and Google Scholar databases.

Right Coronary Artery to Left Ventricular Fistula Complicated by Symptomatic Arrhythmia.

Coronary cameral fistulas (CCFs) are rare and are characterized by an abnormal connection between a coronary artery and any of the four chambers of the heart. Most cases of CCFs are asymptomatic. The most common presentation in symptomatic patients includes chest pain or heart failure; however, arrhythmias are rarely associated.

Tacrolimus-Induced Diffuse Coronary Artery Spasm.

Prinzmetal angina, also known as vasospastic angina, is defined as an intermittent focal or diffuse coronary artery narrowing, which is often associated with transient ST-segment elevation on an electrocardiogram. Also, it could be associated with an atherosclerotic lesion at the site of the spasm. Vasospastic angina might be induced by medications, most commonly with cocaine and other examples which include catecholamines such as epinephrine, norepinephrine, isoproterenol, dopamine, and dobutamine.

The Adult Patient with a Fontan.

The authors summarize the most important anatomic and physiologic substrates of Fontan circulation. Common anatomic substrates include hypoplastic left heart syndrome, tricuspid atresia, double inlet left ventricle, and unbalanced atrioventricular septal defects. After the Fontan operation exercise capacity is limited and the key hemodynamic drivers is limited preload due to a relatively fixed pulmonary vascular resistance.

Percutaneous Device Closure of Patent Ductus Arteriosus in Adult Patients with 10-Year Follow-up.

Objectives: We report our 10-year experience with transcatheter closure of patent ductus arteriosus (PDA) in adult using different closure devices.

Background: Transcatheter closure of PDA in adults can be challenging because of frequently associated comorbidities. Reports on immediate and intermediate-term results of PDA closure are excellent.

A first approach to a neuropsychological screening tool using eye-tracking for bedside cognitive testing based on the Edinburgh Cognitive and Behavioural ALS Screen.

Objective: Reliable assessment of cognitive functions is a challenging task in amyotrophic lateral sclerosis (ALS) patients unable to speak and write. We therefore present an eye-tracking based neuropsychological screening tool based on the Edinburgh Cognitive and Behavioural ALS Screen (ECAS), a standard screening tool for cognitive deficits in ALS.

Methods: In total, 46 ALS patients and 50 healthy controls matched for age, gender and education were tested with an oculomotor based and a standard paper-and-pencil version of the ECAS.

ST-Segment Elevation Myocardial Infarction: Door to Balloon Time Improvement Project.

Background: The purpose of this quality improvement project was to evaluate prospectively the causes of delay for patients with acute ST-segment elevation myocardial infarction (STEMI) requiring primary percutaneous coronary intervention (PCI) upon arrival at the emergency department (ED) and implement recommendations to reduce delays and analyze the impact of recommendations to reduce the door-to-balloon (D2B) time in a newly established cardiac center (King Faisal Cardiac Center (KFCC)). Primary PCI has developed as an effective treatment strategy for acute STEMI, the survival rate and patient outcome are however dependent on the time to treatment. The international benchmark for all programs dealing with acute coronary syndrome patients suffering from STEMI has been established as 90 minutes or less from the time the patient arrives at the hospital to the opening of the affected vessel in the cardiac catheterization laboratory "door-to-balloon time" or D2B.

Cardiac resynchronization therapy in adults with congenital heart disease.

Aims: In adults with congenital heart disease (CHD) heart failure is one of the leading causes of morbidity and mortality but experience with and reported outcome of cardiac resynchronization therapy (CRT) is limited. We investigated the efficacy of CRT in adults with CHD.

Methods And Results: This was a retrospective study including 48 adults with CHD who received CRT since 2003 in four tertiary referral centres.

Long-term outcomes after percutaneous intervention of the internal thoracic artery anastomosis: the use of drug-eluting stents is associated with a higher need of repeat revascularization.

Background: There is a lack of data and absence of clear recommendations regarding the optimal treatment of lesions located at the anastomosis of internal thoracic artery (ITA) grafts and native coronary arteries (CAs). The objective of this study was to assess the long-term outcomes of percutaneous coronary intervention (PCI) at the ITA anastomosis according to delivered treatment, namely deployment of a drug-eluting stent (DES), bare-metal stent (BMS), or balloon angioplasty only (POBA).

Methods: We used a prospective PCI registry at a large Canadian teaching hospital to identify all patients who underwent PCI at the ITA-CA anastomosis between June 2000 and June 2010.

Use of clopidogrel post-coronary artery bypass surgery in canadian patients with acute coronary syndromes.

Background: Randomized trials have established the efficacy of clopidogrel in acute coronary syndromes (ACS). The benefit of clopidogrel has also been observed in the subgroup of ACS patients who subsequently undergo coronary artery bypass surgery (CABG); however, this therapy is discontinued preoperatively and the frequency with which clopidogrel is restarted post-CABG is unknown.

Methods: We examined the pattern of clopidogrel use in the Canadian Global Registry of Acute Coronary Events (GRACE), GRACE2, and CANRACE (2003-2008) post-CABG ACS patients.

Pregnancy outcome of patients with previous four or more caesarean sections.

Between 1994 and 1999, of the 44 357 mothers delivered at the Riyadh Armed Forces Hospital (RAFH), 255 patients had four or more previous caesarean sections (CS). This comprised 0.5% of the obstetric population.

[Results and indications of laparoscopic distal tuboplasty].

We present a retrospective study of a series of 46 patients who have benefited from a laparoscopic treatment for a distal tubal disease. The results have been expressed in terms of tubulars and adherentiels scores, of the type of plastic effected and of the sterility (pure tubular sterility or associated). The global pregnancy rate is 39, 1% of which 34,8% is IUP and 4,3% EP.
