Analysis of the amplified p-wave enables identification of patients with atrial fibrillation during sinus rhythm.

Aim: This study sought to develop and validate diagnostic models to identify individuals with atrial fibrillation (AF) using amplified sinus-p-wave analysis.

Methods: A total of 1,492 patients (491 healthy controls, 499 with paroxysmal AF and 502 with persistent AF) underwent digital 12-lead-ECG recording during sinus rhythm. The patient cohort was divided into training and validation set in a 3:2 ratio.

Surgical technique for acute retrograde type A aortic dissection after zone 2 TEVAR for complicated type B dissection in a 63-year-old patient.

Patients suffering retrograde type A aortic dissection after TEVAR for type B dissection are at higher risk of mortality than their spontanous counterparts and the kind of optimal therapy remains obscure. We present a case of successful open surgical repair where distal open anastomosis was accomplished by cutting off the un-covered stent portion and suturing a vascular prosthesis to the dissected distal aortic arch including the covered stent part. The clinical course was regular.

Endoaneurysmorrhaphy for a Giant Inferobasal Left Ventricular Aneurysm Restoring Mitral Function.

Over the years, the surgery of ventricular postinfarction aneurysm has evolved from linear resection to endoaneurysmorrhaphy using a patch. Technically, several aims that include the restoration of ventricular shape and function, exclusion of dead space, minimization of the risk of thrombus formation and restoration of valve function are pursued. Herein is reported the case of a 58-year-old male with a giant inferobasal aneurysm involving the mitral valve apparatus who underwent successful endoaneurysmorrhaphy.

Impact of feeding method on diaphragm electrical activity and central apnea in preterm infants (FEAdi study).

Background: In preterm infants, it is unknown whether feeding affects neural breathing pattern.

Objectives: By measuring the diaphragm electrical activity (Edi) waveform, we evaluated the effect of enteral feeding and compared the effects of feeding methods on neural breathing pattern and central apnea in very low birth weight preterm infants.

Methods: In a prospective, randomized, crossover study, ten non-ventilated preterm infants with birth weights<1250g and tolerating full feeds were randomized to either bolus feeding (BF) or slow infusion feeding (SF) over 90min, followed by crossover to the other method at the next feed.

High-flow nasal cannulae are associated with increased diaphragm activation compared with nasal continuous positive airway pressure in preterm infants.

Aim: High-flow nasal cannulae (HFNC) are increasingly used for respiratory management of preterm infants. However, their ability to provide support compared to nasal continuous positive airway pressure (CPAP) has been questioned. We compared the effect of HFNC versus nasal CPAP on diaphragm electrical activity (EAdi) in preterm infants.
