Background: Dexmedetomidine (DEX) is a highly selective α-2 agonist with many desirable effects including analgesia, improvement of hemodynamic stability, and potential myocardial and renal protection. The aim of this study was to investigate the effect of DEX on patients undergoing off-pump coronary artery bypass (OPCAB) grafting with regard to less pain medication, earlier extubation, faster transfer to normal ward, and cardiac protection.
Patients And Methods: From January 2012 to March 2015, 464 patients receiving OPCAB were included for retrospective analysis.
We describe the first case of a pregnant woman presenting with an acute inverted takotsubo-like cardiomyopathy caused by a postpartum diagnosed hemorrhagic pheochromocytoma, successfully treated with percutaneous venoarterial extracorporeal membrane oxygenation (va-ECMO). During admission, an emergency cesarean delivery had to be performed. The fetus needed resuscitation for 5 minutes.

Background: Sonoclot is used to measure kaolin-based activated clotting time (kACT) for heparin management. Apart from measuring kACT, the device assesses the patient's coagulation status by glass bead-activated tests (gbACTs; measuring also clot rate [CR] and platelet function [PF]). Recently, a new version of the Sonoclot has been released, and the redesign may result in performance changes.
View Article and Find Full Text PDFObjectives: The aim of the study was to determine if Sonoclot with its sensitive glass bead-activated, viscoelastic test can predict postoperative bleeding in patients undergoing cardiac surgery at predefined time points.
Design: A prospective, observational clinical study.
Setting: A teaching hospital, single center.
Tricuspid regurgitation (TR) in patients undergoing surgery for mitral valve (MV) increases morbidity and mortality, especially in case of a poor right ventricle. Does repair of mild-to-moderate insufficiency of the tricuspid valve (TV) in patients undergoing MV surgery lead to a benefit in early postoperative outcome? A total of 22 patients with mild-to-moderate TR underwent MV repair and concomitant TV repair with Tri-Ad (Medtronic ATS Medical Inc., Minneapolis, Minnesota, United States) and Edwards Cosgrove (Edwards Lifesciences Irvine, California, United States) rings.

The Heartstring device allows constructing proximal bypass anastomoses without side-clamping of the aorta.
Methods: This retrospective study describes 260 consecutive patients who underwent OPCAB surgery; 442 proximal anastomoses were performed with the Heartstring device in this series.
Aims: Collagen degradation in atherosclerotic plaques with thin fibrous caps renders them more prone to rupture. Fibroblast activation protein (FAP) plays a role in arthritis and tumour formation through its collagenase activity. However, the significance of FAP in thin-cap human fibroatheromata remains unknown.

Oxidized regenerated cellulose is widely used as a bioabsorbable topical hemostatic agent. Postoperative visualization of this material through routine chest imaging, such as conventional radiography, computer tomography (CT), magnetic resonance imaging as well as sonography, may prove difficult and, to our knowledge, is not described in the literature. We describe a case where the mediastinal packing with Surgicel™ Nu-Knit™ after a mitral valve repair procedure led to a delayed obstruction of the superior vena cava, necessitating a re-thoracotomy and curettage of the hemostatic material.

It is rare that pilots undergo aortic valve surgery, and the confirmation of flight-licensing requirements after aortic valve replacement (AVR) is a challenge for the patient's cardiac surgeon and, particularly, for the Aeromedical Examiner (AME). Only AMEs are able to determine the flight status of pilots.

The patient suffered repeated admissions for iterative sterile wound necrosis, leading to two generator re-implantations. No bacterial infection was detected in the microbiological screening tests.

Aortic complications are very rare during off-pump coronary artery bypass grafting (OPCAB). When they occur, the mortality is high. We report a case of perforation of the posterior aortic wall after punching out the hole in the ascending aorta with an automatic aortic cutter to avoid clamping for the proximal anastomosis during a routine OPCAB procedure.

However, aprotinin prolongs ACT measurements. Recently, a new so-called 'aprotinin-insensitive' ACT test (SaiACT) has been developed for the SONOCLOT analyzer.

A reduction in the number of right and left atrial incisions could decrease the operative time. The aim of this study was to assess the results of a mini-maze operation and to define predictors of its failure.
