Performing coronary grafts on aspirin is associated with increased postoperative bleeding but may decrease the long-term hazard of coronary events.

Core temperature reflects the temperature of the internal organs. Proper temperature measurement is essential to diagnose and treat temperature impairment in patients. However, an accurate approach has yet to be established. Depending on the method used, the obtained values may vary and differ from the actual core temperature. There is an ongoing debate regarding the most appropriate anatomical site for core temperature measurement. Although the measurement of body core temperature through a pulmonary artery catheter is commonly cited as the gold standard, the esophageal temperature measurement appears to be a reasonable and functional alternative in the clinical setting. This article provides an integrative review of invasive and noninvasive body temperature measurements and their relations to core temperature.

Data from a prospective cohort of patients undergoing aortic valve repair and root reconstruction reinforce the satisfactory medium-term results obtained with valve reconstruction. Further analysis of these patient outcomes is necessary to draw definitive conclusions on operative techniques.

IntroductionTranscatheter paravalvular leak closure (TPVLC) has become an established treatment option but is mostly performed with off-label use of different non-dedicated occluders. The first one specifically designed for TPVLC is the paravalvular leak device (PLD – Occlutech).AimWe present initial short-term results of a prospective registry intended to assess the safety and efficacy of TPVLC with PLD.Material and methodsWe screened patients with paravalvular leak (PVL) after surgical valve replacement (SVR). Heart failure symptoms and/or hemolytic anemia were indications for TPVLC. Patients were selected according to PVL anatomy by RT 3D TEE. Only those considered appropriate for closure with a single PLD were enrolled. The procedures were performed via transvascular or transapical access using type W (waist) PLDs only.ResultsThirty patients with 34 PVLs (18 aortic, 16 mitral) were included. We implanted 35 PLDs with a total device success rate of 94.3% (100% for aortic, 88.2% for mitral). The procedural success rate, encompassing device success without in-hospital complications, was 94.1% (100% for aortic, 93.8% for mitral). During the follow-up period we recorded an increase of hemoglobin concentration (3.9 to 4.1 g/dl), red blood count (11.6 to 12.2 M/mm3) and functional improvement by NYHA class.ConclusionsParavalvular leak device type W is a promising TPVLC device, but meticulous preselection of patients based on imaging of PVL anatomy is a prerequisite. A PLD should only be chosen for channels shorter than 5 mm. Size of the device should match the PVL cross-sectional area without any oversizing. Such an approach facilitates high device and procedural success rates.

OBJECTIVES This study presents the results of 17 years of experience with bicuspid aortic valve (BAV) repair and the analysis of factors associated with repair failure and early echocardiographic outcome. METHODS Between 2003 and 2020, a total of 206 patients [mean age: 44.5 ± 15.2 years; 152 males (74%)] with BAV insufficiency with or without aortic dilatation underwent elective aortic valve repair performed by a single surgeon with a mean follow-up of 5 ± 3.5 years. The transthoracic echocardiography examinations were reported. RESULTS There were no deaths during the hospital stay, and all but 1 patient survived the follow-up period (99.5%). Overall, 10 patients (5%) developed severe insufficiency and 2 (1%) developed aortic dilatation requiring reoperation. Freedom from reoperation at 7 years reached 91.8%. Type 2 BAV configuration [hazard ratio (HR) 3.9; 95% confidence interval (CI): 1.01–60; P = 0.049], no sinotubular junction remodelling (HR 7; 95% CI: 1.7–23; P = 0.005), no circumferential annuloplasty (HR 3.9; 95% CI: 1.01–64; P = 0.047) and leaflet resection (HR 5.7; 95% CI 1.2–13. P = 0.017) have been identified as a risk factor of redo operation. Parameters of the postoperative left ventricle reverse remodelling improved significantly early after the operation and later at 2 years evaluation. CONCLUSIONS The repair of BAV offers good short- and mid-term results providing a significant reverse left ventricular remodelling. Type 0 BAV preoperative configuration, circumferential annuloplasty and sinotubular junction remodelling are associated with better repair durability.
