Patent Foramen Ovale Repair at the Time of Double Lung Transplantation: Necessary or Not?
ConclusionsThe protective effect of PFO repair remains unclear. However, is not associated with an increased incidence of stroke or postoperative mortality following LTx. This suggests that repair of PFO, with its inherent increase in surgical complexity, is not required and outcomes are acceptable.This article is protected by copyright. All rights reserved.

Efficacy of Prophylactic Intra‐Aortic Balloon Pump Therapy in Chronic Heart Failure Patients Undergoing Cardiac Surgery
This study investigated the efficacy of prophylactic intraoperative intra‐aortic balloon pump (IABP) usage in chronic heart failure patients with severely reduced left ventricular function undergoing elective cardiac surgery. Between January 2008 and December 2012, 107 patients with severely reduced left ventricular ejection fraction (LVEF <35%) received prophylactic intraoperative IABP implantation during open‐heart surgery. Surgical procedures performed were isolated coronary artery bypass grafting (CABG) in 35 patients (32.7%), aortic valve replacement in 12 (11.2%), mitral valve repair or replacement in 15 (14.0...

Early outcomes of extra-thoracic debranching thoracic endovascular aortic repair for distal aortic arch disease
In conclusion, the early outcomes of extra-thoracic debranching TEVAR in high-risk patients with distal aortic arch disease were satisfactory and encouraging, compared with conventional arch replacement. Extra-thoracic debranching TEVAR has the advantage of less invasiveness and no possibility of sternal infection.

Experimental Investigation of Left Ventricular Flow Patterns After Percutaneous Edge ‐to‐Edge Mitral Valve Repair
Abstract Mitral valve percutaneous edge‐to‐edge repair (PEtER) is a viable solution in high‐risk patients with severe symptomatic mitral regurgitation. However, the generated double‐orifice configuration poses challenges for the evaluation of the hemodynamic performance of the mitral valve and may alter flow patterns in the left ventricle (LV) during diastole. This in vitro study aims to evaluate the hemodynamic modifications following a simulated PEtER. A custom‐made mitral valve was developed, and two configurations were tested: (i) a single‐orifice valve with mitral regurgitation and (ii) a double‐orifice ...

Clinical results and medical costs of thoracic endovascular aortic repair in patients over 80  years of age
AbstractThoracic endovascular aortic repair (TEVAR) is expected to be minimally invasive, especially in older patients. However, clinical results of TEVAR in octogenarians including medical costs are limited. Between 2010 and 2016, a total of 57 patients over 80  years of age (mean age 84.1 ± 3.4 years) underwent TEVAR at our hospital. The proximal landing zone (PLZ) was zone 0 in 7 patients (12.3%), zone 1 in 10 patients (17.5%), zone 2 in 9 patients (15.8%), zone 3 in 13 patients (22.8%), and zone 4 in 18 patients (31.6%). The mean follow-up time w as 23 ± 19 months (range 1–71 months). The follow-up rate...

Clampless aortic punch system for making a large-diameter access route without side-biting clamp: a preliminary study
This study aimed to present the results of our preliminary study on the clampless aortic punch system (APS). The swine aorta was used as experimental specimen (diameter 16 –20 mm). A 10-mm collagen-impregnated knitted Dacron graft was anastomosed to the aorta, and the APS was inserted into it. After piercing the aorta with the inner fish hook of the APS, the aortic wall was scooped out by an outer round cutter. Three different-angled cutters (0°, 15°, and 30°) w ere tested three times. The diameter of the punched-out lesion ranged from 6 to 9 mm (median 8 mm). Macroscopically, no major vessel injuries were seen 15�...

Should we touch tricuspid valve at the time of LVAD implantation? A young patient series
CONCLUSION: Although the risk of late RVF may increase in patients with preoperative severe TI, not intervening in TI during LVAD implantation does not cause adverse clinical outcomes in the early period.PMID:37334781 | DOI:10.1177/03913988231181604
