Biventricular function after Ebstein anomaly repair from a single-center echocardiography study.

Objective: We aimed to examine biventricular remodeling and function after Ebstein anomaly (EbA) surgical correction using echocardiographic techniques, particularly, the relations between the biventricular changes and the EbA types.

Methods: From April 2015 to August 2022, 110 patients with EbA were included in this retrospective study based on the Carpentier classification. Echocardiography assessments during the preoperative, early, and mid-term postoperative periods were performed.

Outcomes of Ebstein's Anomaly Patients Treated with Tricuspid Valvuloplasty or Tricuspid Valve Replacement: Experience of a Single Center.

Background: The incidence of Ebstein's anomaly is extremely low, and except for the Mayo Clinic, no cardiac center has reported on a sufficient number of patients. The aim of our study was to report the outcomes of Ebstein's anomaly patients treated with tricuspid valvuloplasty (TVP) or tricuspid valve replacement (TVR).

Methods: TVP or TVR was performed in 245 patients from July 2006 to April 2016.

Surgical Treatment of Secondary Tricuspid Regurgitation: Insight Derived From Annulus Sizes and Tethering Distances.

Background: The main goal of this study was to explore the feasibility of stratifying patients with secondary tricuspid regurgitation (TR) into different risk levels, and to compare the surgical outcomes of patients within different risk levels who underwent different tricuspid valve repair (TVP) approaches.

Methods: One hundred and one patients with left-sided valvular disease underwent either left-sided valvular replacement or repair, and 79 patients underwent concomitant TVP. Depending upon their tricuspid annulus diameter and tethering distances, the patients were assessed using 4 risk levels.

Myocardial scar identified by magnetic resonance imaging can predict left ventricular functional improvement after coronary artery bypass grafting.

Background: Previous studies have shown that viable myocardium predicts recovery of left ventricular (LV) dysfunction after revascularization. Our aim was to evaluate the prognostic value of myocardial scar assessed by late gadolinium-enhanced cardiovascular magnetic resonance imaging (LGE-CMR) on functional recovery in patients undergoing coronary artery bypass grafting (CABG).

Methods: From November 2009 to September 2012, 63 patients with reduced left ventricular ejection fraction (LVEF) referred for first-time isolated CABG were prospectively enrolled, 52 were included in final analysis.

Surgical management of left circumflex coronary artery fistula: a 25-year single-center experience in 29 patients.

Background: Left circumflex coronary artery (LCX) fistula is rare, and surgical experience is limited. We report our experience with 29 patients with LCX fistula during a 25-year period in terms of clinical features, pathology, surgical procedure, and late outcomes.

Methods: Between June 1988 and July 2013, 29 patients (19 males, 10 females; median age, 10 years) with LCX fistula were treated surgically and followed up.

Surgical treatment for primary mitral valve tumor: a 25-year single-center experience.

Objective: Primary mitral valve (MV) tumor is a rare lesion, and to date, there have been few larger surgical series of MV tumors. We retrospectively analyzed 11 cases of primary MV tumors regarding clinical and pathological features, surgical procedure and long-term outcomes.

Methods: From November 1983 to December 2008, we operated on 11 patients (age 36.

Repair of a ventricular septal defect in a patient with left lung agenesis.

Congenital heart disease combined with lung agenesis is extremely rare. We report a case of a 5-year-old female with a ventricular septal defect (VSD) and left lung agenesis with severe pulmonary hypertension who underwent successful closure of the VSD. 

Redoing a bioprosthetic tricuspid valve replacement with pacemaker wire through the ruined bioprosthetic valve orifice.

Severe tricuspid regurgitation with permanent pacemaker wire passing through the orifice of bioprosthetic tricuspid valve is extremely rare. We present a case of such kind of patient and redid bioprosthetic tricuspid valve replacement. A hawk mouth forceps for bone surgery was used to cut off the mental ring of ruined bioprosthetic tricuspid valve and the ruined valve was removed.

Surgical management of double-orifice tricuspid valve.

Background And Aim Of The Study: Double-orifice tricuspid valve (DOTV) is a very rare cardiac malformation. We sought to describe our experience with surgical management of this defect in three cases.

Material And Methods: Between September 2008 and October 2010, three patients (one male, two females) with DOTV were treated at our institute.

Diagnosis, operation, recurrence, metastasis, and death: a case of primary cardiac rhabdomyosarcoma.

We present a case report of a 48-year-old man with a huge left atrial rhabdomyosarcoma who presented as severe mitral stenosis and accepted emergency surgery. Two years later, a pathologic fracture revealed osseous metastasis, and intracardiac recurrence was detected by echocardiography. The patient died of multiple organ failure in the end.

[Surgical treatment of giant coronary artery aneurysm].

Objective: To discuss the clinical features and surgical treatments of giant coronary artery aneurysm (CAA).

Methods: From July 1996 to October 2004, 6 giant CAA patients were underwent surgery at Fuwai hospital. Three cases were underwent CAA resection, 2 concomitant coronary bypass, 3 reconstruction.

A study on naphtha catalytic reforming reactor simulation and analysis.

A naphtha catalytic reforming unit with four reactors in series is analyzed. A physical model is proposed to describe the catalytic reforming radial flow reactor. Kinetics and thermodynamics equations are selected to describe the naphtha catalytic reforming reactions characteristics based on idealizing the complex naphtha mixture by representing the paraffin, naphthene, and aromatic groups by single compounds.

[Radionuclide pulmonary perfusion imaging in evaluating pulmonary hypertension in patients with rheumatic heart disease].

Objective: To evaluate the degree of pulmonary hypertension in patients with rheumatic heart disease using radionuclide pulmonary perfusion imaging.

Methods: The pulmonary perfusion in 25 patients with rheumatic heart disease was examined using scintigram with macroaggregates of (99m)Tc-labeled human serum albumin (PPS) before and 7 days after operation. PPS was analyzed for (1) pulmonary perfusion steady time (PT), right upper and lower lung count ratio (RULR).
