Rare case series of adult interrupted aortic arch.

Unlabelled: Interrupted aortic arch (IAA) is a rare congenital heart condition where there is a complete discontinuation between the ascending and descending aorta. The association with a patent ductus arteriosus or developed arterial collateral allows survival until adulthood in extremely rare cases. We report a case series of adult forms of IAA.

Microcatheter-versus wire-based measurement of the fractional flow reserve.

Background: Fractional flow reserve (FFR) guided-percutaneous interventions is nowadays the gold standard for optimal coronary artery revascularization. While multiple pressure guidewires have been validated, the use of microcatheter for FFR measurements is still a matter of debate.

Objective: The aim of this study was to investigate the crossing profile characteristics of the NAVVUS microcatheter as compared with the COMET pressure wire.

Fractional flow reserve and non-hyperemic indices: Essential tools for percutaneous coronary interventions.

Hemodynamical evaluation of a coronary artery lesion is an important diagnostic step to assess its functional impact. Fractional flow reserve (FFR) received a class IA recommendation from the European Society of Cardiology for the assessment of angiographically moderate stenosis. FFR evaluation of coronary artery disease offers improvement of the therapeutic strategy, deferring unnecessary procedures for lesions with a FFR > 0.

Dilated cardiomyopathy: An unusual and severe condition in juvenile systemic lupus erythematosus.

Background: Systemic juvenile lupus erythematosus can affect any organ including the heart. While pericarditis and endocarditis are the most common cardiac complications, dilated cardiomyopathy remains rare. We report the full recovery of dilated cardiomyopathy in a girl with juvenile lupus.
