First-in-Man Case Report
Giant cell myocarditis is a rare and highly lethal disorder with
resultant cardiac insufficiency. It necessitates aggressive immune
suppression therapy, although the results are often fatal. When
it affects only the atria, the characteristics of the disease changes
completely. In this case report, we present atypical presentation
of atrial giant cell myocarditis with mass lesion, which completely
resolved after successful surgical resection without immuno
suppression therapy. (Source: Brazilian Journal of Cardiovascular Surgery)

Heat Shock Proteins: Protection and Potential Biomarkers for Ischemic
Injury of Cardiomyocytes After Surgery
The heat shock proteins are endogenous proteins with the ability
to act as molecular chaperones. Methods that provide cell protection
by way of some damage can positively influence the results of
surgery. The present review summarizes current knowledge
concerning the cardioprotective role of the heat shock proteins as
occurs in heart damage, including relevant information about the
stresses that regulate the expression of these proteins and their
potential role as biomarkers of heart disease. (Source: Brazilian Journal of Cardiovascular Surgery)

Update in Heart Rhythm Abnormalities and Indications for Pacemaker
After Transcatheter Aortic Valve Implantation
Objective: Rhythm abnormalities following transcatheter aortic valve implantation (TAVI)
and indications for permanent pacemaker implantation (PPI) were reviewed,
which aren't well established in the current guidelines. New left bundle
branch block and atrioventricular block are the most common
electrocardiographic changes after TAVI. PPI incidence ranges from 9-42% for
self-expandable and 2.5-11.5% for balloon expandable devices. Not only
anatomical variations in conduction system have an important role in
conduction disorders, but different valve characteristics and their ...

Survival and Risk Factors Among Dialytic Acute Kidney Injury Patients
After Cardiovascular Surgery
Objective: Acute kidney injury (AKI) is a frequent postoperative complication after
cardiovascular surgery. It has been described as a predictor of decreased
survival rates, but how dialysis decreases survival when initiated on the
postoperative period has yet to be determined. To analyze the survival of
patients who presented postoperative AKI requiring dialysis up to 30 days
after cardiovascular surgery and its risk factors is the aim of this study.Methods: Of the 5,189 cardiovascular surgeries performed in a 4-year period, 157
patients developed AKI requiring dialysis in the pos...

Rational Use of Mechanical Circulatory Support as a Bridge to
Pediatric and Congenital Heart Transplantation
Introduction: Donor shortage and organ allocation is the main problem in pediatric heart
transplant. Mechanical circulatory support is known to increase waiting list
survival, but it is not routinely used in pediatric programs in Latin
America.Methods: All patients listed for heart transplant and supported by a mechanical
circulatory support between January 2012 and March 2016 were included in
this retrospective single-center study. The endpoints were mechanical
circulatory support time, complications, heart transplant survival and
discharge from the hospital.Results: Twenty...

Functional Performance of Different Venous Limb Options in Simulated
Neonatal/Pediatric Cardiopulmonary Bypass Circuits
Objective: Hemodilution is a concern in cardiopulmonary bypass (CPB). Using a smaller
dual tubing rather than a single larger inner diameter (ID) tubing in the
venous limb to decrease prime volume has been a standard practice. The
purpose of this study is to evaluate these tubing options.Methods: Four different CPB circuits primed with blood (hematocrit 30%) were
investigated. Two setups were used with two circuits for each one. In Setup
I, a neonatal oxygenator was connected to dual 3/16" ID venous limbs
(Circuit A) or to a single 1/4" ID venous limb (Circuit B); and in Setup II, ...
