Impact of stent strut link location in proximal balloon edge dilation technique for bifurcation percutaneous coronary intervention
AbstractThe single-stent strategy has generally been accepted as the default approach to bifurcation percutaneous coronary intervention. We have proposed the proximal balloon edge dilation (PBED) technique to prevent stent deformation during side branch (SB) dilation. This bench study aimed to evaluate the impact of stent link location and stent design on stent deformation, obstruction by stent struts at a jailed SB ostium, and incomplete stent apposition in the proximal optimization technique (POT)-PBED procedure. A coronary bifurcation model was used. We intentionally set the absence or presence of stent link on the cari...

Relationship between patent foramen ovale anatomical features and residual shunt after patent foramen ovale closure
This study aimed to evaluate the relationship between the anatomical features of PFO and residual shunt. The degree of residual shunt and its relationship with the anatomical features of PFO were evaluated in 106 patients who underwent PFO closure at our institution between March 2011 and January 2022 and in whom contrast transthoracic echocardiography was performed 1  year later. The mean PFO tunnel length was 9.3 ± 3.6 mm and the mean PFO height was 3.2 ± 2.2 mm. Atrial septal aneurysm (ASA) was found in 37 patients. After PFO closure, residual shunt was observed in 28 patients (grade 1, n = 8; grade 2, ...

Diagnosis and treatment of cardiovascular disease in patients with heritable connective tissue disorders or heritable thoracic aortic diseases
AbstractPatients with heritable connective tissue disorders (HCTDs), represented by Marfan syndrome, can develop fatal aortic and/or arterial complications before age 50. Therefore, accurate diagnosis, appropriate medical treatment, and early prophylactic surgical treatment of aortic and arterial lesions are essential to improve prognosis. Patients with HCTDs generally present with specific physical features due to connective tissue abnormalities, while some patients with heritable thoracic aortic diseases (HTADs) have few distinctive physical characteristics. The development of genetic testing has made it possible to prov...

Volume –outcome relationships for extracorporeal membrane oxygenation in acute myocardial infarction
In conclusion, ECMO was infrequently used in a setting of acute MI at each hospital annually. An observed rate of ECMO use was not associated with observed/predicted in-hospital mortality ratio, while the observed/predicted in-hospital mortality ratio was lowest when ECMO was used as predicted, suggesting that standardized ECMO use may be an institutional quality indicator in acute MI.Graphical abstract (Source: Cardiovascular Intervention and Therapeutics)

Feasibility of contrast-free left atrial appendage closure with WATCHMAN FLX device for patients with chronic kidney disease
The objective of this study was to evaluate the safety and feasibility of contrast-free LAAC with WATCHMAN FLX device for patients with CKD. Among 141 patients undergoing LAAC using the WATCHMAN FLX between May 2021 and March 2023, we performed LAAC without contrast media in 10 patients. Procedural and follow-up results were evaluated. The device size was selected based on the transesophageal echocardiographic (TEE) measurements. The device shape was assessed by fluoroscopy, and the device position was adjusted by TEE images. The mean age was 78  ± 4.9 years, CHADS2 score was 3.2  ± 1.1, and the estimated glomer...

Trajectory of pulmonary congestion during TAVR
AbstractPatients with severe aortic stenosis often experience pulmonary congestion due to incremental afterload. The trajectory of pulmonary fluid volume during transcatheter aortic valve replacement (TAVR) remains uncertain. Remote dielectric sensing (ReDS) is a recently introduced device for non-invasive quantification of lung fluid volume without expert techniques. We evaluated the trajectory of ReDS values during TAVR and its prognostic implications. Patients with severe aortic stenosis who underwent ReDS measurements upon admission and at the index discharge after TAVR between 2021 and 2022 were eligible. They were fo...

Changes in exercise stress echocardiographic parameters before and after transcatheter mitral valve edge-to-edge repair
This study is aimed to assess and compare the hemodynamic and symptomatic changes in patients with significant secondary MR during exercise stress echocardiography (ESE) before and after transcatheter edge-to-edge repair (TEER). The study included a total of 15 patients with secondary MR who underwent ESE before and after TEER using the MitraClip system (Abbott, Abbott Park, IL, USA). Echocardiographic data of ESE were collected both before the procedure and during the follow-up visit at 3  months. During the one-year postoperative observation period, the rate of readmission due to heart failure was 13% (n = 2), with ...
