The value of right heart contrast echocardiography combined with migraine rating scale in evaluating the efficacy of patent foramen ovale closure.

Objectives: To investigate the clinical values of right heart contrast transthoracic echocardiography (cTTE) combined with migraine rating scale in evaluating the efficacy of patent foramen ovale (PFO) closure.

Methods: From January 2018 to December 2021, a total of 68 hospitalized patients, 21 males and 47 females, who were treated with transcatheter closure of PFO-induced migraine in the Heart Center of the First Affiliated Hospital of Tsinghua University were selected, with the age of 38.4 ± 11.

Transcatheter Tricuspid Valve-in-Valve Replacement Using a J-Valve System for a Failed Tricuspid Bioprosthesis.

Background: Redo operation for failed tricuspid bioprosthetic valves is associated with high morbidity and mortality. Transcatheter tricuspid valve-in-valve implantation has become an acceptable option for high-risk patients with a failed tricuspid bioprosthesis. We present a case of successful tricuspid valve-in-valve implantation using a J-valve in a failed tricuspid bioprosthesis position.

Left ventricle reverse remodeling in chronic aortic regurgitation patients with dilated ventricle after aortic valve replacement.

Background: Aortic valve replacement (AVR) for chronic aortic regurgitation (AR) with a severe dilated left ventricle and dysfunction leads to left ventricle remodeling. But there are rarely reports on the left ventricle reverse remodeling (LVRR) after AVR. This study aimed to investigate the LVRR and outcomes in chronic AR patients with severe dilated left ventricle and dysfunction after AVR.

Open heart surgery or echocardiographic transthoracic or percutaneous closure in secundum atrial septal defect: a developing approach in one Chinese hospital.

Background: To study the clinical manifestations and advantages of open-heart surgery and echocardiographic transthoracic or percutaneous closure with secundum atrial septal defect (ASD). The surgeon's learning curve was also analyzed.

Methods: In all, 115 consecutive patients with ASD from May 2013 to May 2019 were enrolled.

Intraoperative Transesophageal Echocardiography in the Operation of Ebstein's Anomaly: A Retrospective Study.

Background: Ebstein's anomaly (EA) has various spectrums in clinical and anatomic features. This study aimed to report the experience of two-dimensional intraoperative transesophageal echocardiography (2D-ITEE) during the EA surgery and to analyze the characteristics of the tricuspid valve (TV) by comparing the data from 2D-ITEE with the results from the surgery.

Methods: 2D-ITEE data of 164 patients with EA who were operated in the First Hospital of Tsinghua University between July 2004 and April 2014 were retrospectively analyzed in this study.

Optimal noninvasive assessment of initial left ventricular dysfunction in children with ectopic atrial tachycardia.

Unlabelled: Tissue Doppler imaging (TDI) can identify cardiac dysfunction in adults. This study is aimed to improve early identification of initial left ventricular (LV) dysfunction secondary to ectopic atrial tachycardia (EAT) in children by TDI. A total of 70 children with EAT were included in the present study.

Persistent fifth aortic arch with interrupted aortic arch.

Persistent fifth aortic arch (PFAA) is one of the rarest congenital anomalies. We report a seven-month-old male with PFAA with upper arch interruption and lower arch coarctation diagnosed by echocardiogram and multidetector computed tomography.

[The evaluation of cytocompatibility of mesenchymal stem cells on random biopolyster scaffolds].

Mesenchymal stem cells (MSCs) were isolated from the bone marrow of rabbits and inoculated respectively on 3D scaffolds of poly (3-Hydroxybutyrate-co-3-Hydroxyvalerate) (PHBV), poly (butylenes succinate) (PBS) and the blends for evaluation of their cytocompatibilities in vitro. It was found that the blends of less microporous possessed the best performance on attachment and proliferation of MSCs in the six configurations. The toluiding blue staining showed the best morphology of mensenchymal stem cells (MSCs) on the blends of less microporous blends.
