Clinical Equivalence of Trubond® and Ethibond® Braided Polyester Sutures for Valvular Prosthesis Fixation During Aortic or Mitral Valve Replacement: A Single-Blind Randomized Controlled Trial.

Background Paravalvular leak (PVL) following valve replacement is a serious cardiovascular complication that increases morbidity and mortality. Valve replacement with the interrupted suture technique using polyester suture provides adequate tensile strength and reduces the probability of tissue reaction. This study compared the clinical equivalence of Trubond®(Healthium) and Ethibond® (Ethicon, Johnson & Johnson) braided polyester sutures for valvular prosthesis fixation using interrupted suturing, with respect to the proportion of subjects having PVL after aortic valve (AV) or mitral valve (MV) replacement. Methodology Patients undergoing AV/MV replacement were enrolled and randomized in this study. The primary endpoint of this prospective, multicentric, two-arm, randomized (1:1), parallel-group, single-blind study (December 2020-October 2022) was the presence of PVL in Trubond® (n = 40) and Ethibond® (n = 42) groups within 26 weeks of surgery. The secondary endpoints included event rate of all-cause mortality, cardiac death, stroke, myocardial infarction, re-hospitalization, re-intervention, wound infection, operative time, intraoperative suture parameters, postoperative hospital stay, time to resume normal activities and work, quality of life, patient satisfaction, and adverse events in both groups. Results Patients who underwent AV/MV replacement and were followed up until 26 weeks had no incidence of PVL or other postoperative complications. No requirement for readmission or re-intervention was noted in both groups. Intraoperative suture handling characteristics, operative time, and hospital stay were also comparable between the groups. With each follow-up, subjects in both groups exhibited improved postoperative functional abilities, quality of life, and health status. Conclusions Trubond® braided polyester suture is clinically equivalent to Ethibond® braided polyester suture. Trubond® suture is safe and effective for valvular prosthesis fixation in patients undergoing AV or MV replacement.

Repair of a distal ductal origin of the left pulmonary artery associated with a ventricular septal defect.

Absence of the main branch of the pulmonary artery (PA) with an intracardiac defect is commonly associated with conotruncal cardiac anomaly. It is rarely associated with a ventricular septal defect and PA hypertension. We describe a surgical technique to implant an aberrant left PA to the main PA in a case of a ventricular septal defect, severe pulmonary hypertension, and distal ductal origin of the left PA.

Surgical closure of sinus venosus atrial septal defect using a single patch--transcaval repair technique.

OBJECTIVE: We would like to share our experience of surgical repair of sinus venosus atrial septal defect (ASD) using a simple "transcaval repair technique." METHOD: Between January 2007 and October 2010, 48 consecutive patients of sinus venosus ASD underwent surgical repair using transcaval repair technique at our institute. Their ages ranged from 5 to 15 years and male to female ratio was 1.6:1. The principles of the technique were longitudinal incision over the lateral aspect of superior vena cava (SVC) at the entry point of anomalous right pulmonary veins, use of a single autologous untreated pericardial patch, and finally closure of the caval incision in such a way that the patch gets sandwiched between two caval lips. RESULTS: All 48 patients came off cardiopulmonary bypass in sinus rhythm. The average pressure gradient across the patch was 3 mmHg. Immediate postoperative electrocardiograms and echocardiograms showed all patients were in sinus rhythm with no residual shunt and no pulmonary or systemic venous obstruction respectively, except in one patient who required SVC augmentation. The follow-up was done at three months (100%), one year, and two years. All patients were asymptomatic and their electrocardiograms and transthoracic echocardiograms revealed sinus rhythm, no residual shunt, and no obstruction to systemic or pulmonary venous drainage, respectively. There was no early or late mortality. CONCLUSION: We conclude that this technique is safe and simple for the repair of selected cases of sinus venosus atrial septal defect with partial anomalous pulmonary venous connection and it preserves the sinoatrial node function after surgery.

Echocardiographic diagnosis and surgical closure of coronary sinus type of atrial septal defect.

Coronary sinus type of atrial septal defect (ASD CS) is a rare cardiac anomaly and is rarely diagnosed by only transthoracic echocardiography prior to surgical operation. We now describe a technique to treat this defect with the aid of two-dimensional echocardiography, which prevents trauma to the conduction system and maintains drainage from the coronary sinus into the right atrium (RA).

Aorto-left atrial tunnel: a rare entity.

Aorto-left atrial tunnel (ALAT) is a vascular channel that originates from 1 of the sinuses of Valsalva and terminates in the left atrium. The aorto-left atrial tunnel is an extremely rare anomaly. We describe here a case of congenital aorto-left atrial tunnel in a 4-year-old child who underwent successful surgical ligation with good immediate and early results.

Giant ventricular myxoma obstructing right ventricular outflow tract.

Intracardiac myxoma is predominantly located in the left atrium but their location in the right ventricle is quite unusual. We present a case in which successful excision of the tumor was done through bicameral approach.
