Author

Malankar, Dhananjay P., Mali, Shivaji, Dhake, Shyam, Soni, Bharat, Kandavel, Dinesh, Mhatre, Amit, Bind, Dilip, Bhargava, Rajat, Raj, Jinil, Sheth, Ronak, and Garekar, Swati

Abstract

Different surgical techniques have been described for the primary repair of anomalous left coronary artery arising from the pulmonary artery (ALCAPA); however, very few techniques are described for management of coronary artery occlusion following ALCAPA repair. We present a case of a 7-year-old girl with left main coronary atresia status-post left coronary button transfer for ALCAPA in infancy. She underwent redo-sternotomy and left subclavian artery-to-left main coronary artery bypass plus mitral valve repair and had an uneventful postoperative course.

Abstract

Background : Various operative strategies are described for the Fontan procedure. In this study, we describe our short-term results and technique of Fontan procedure on cardiopulmonary bypass (CPB) and deep hypothermic circulatory arrest (DHCA). Methods : This was a retrospective study of 32 patients, median age of 6 years (4–19 years) and median weight of 20 kg (13–51 kg), who underwent Fontan procedure on CPB and DHCA from July 2016 to July 2021. Results : The median CPB time was 125 min (77–186 min), the median DHCA time was 42 min (27–50 min), and the median Fontan pressure was 14 mmHg (10–18 mmHg). The median time to extubation was 4 h (1–20 h), the duration of chest tube drainage was 8 days (5–24 days), and the median intensive care unit stay was 4 days (3–8 days). The presence of heterotaxy was associated with longer duration of pleural drainage (P = 0.01). There was no operative mortality and no major adverse events such as seizures, gross neurological deficits, or arrhythmias in the postoperative period. Conclusions : Fontan procedure can be safely performed on CPB and DHCA with good operative results. This operative strategy may be used in special circumstances like in patients with situs and systemic venous anomalies and those requiring repair of a complex intracardiac defect. Long-term follow-up will be required to evaluate if this strategy has any impact on the neurodevelopmental outcome and the long-term sequelae of Fontan. [ABSTRACT FROM AUTHOR]

22. Single-Stage Unifocalization and Intracardiac Repair Using Two Tube Grafts.

Author

Malankar, Dhananjay Prakash, Mali, Shivaji, Garekar, Swati, and Sheth, Ronak

Abstract

Unifocalization of the major aortopulmonary collaterals (MAPCAs) followed by intracardiac repair with ventricular septal defect (VSD) closure and restoration of right ventricle-to-pulmonary artery continuity is the ultimate treatment goal in a case of VSD with pulmonary atresia and MAPCAs. It may be achieved in a single stage or may require multiple surgeries. We present a case of a 2-year-old boy with VSD with pulmonary atresia who underwent single-stage unifocalization of MAPCAs through the midline followed by intracardiac repair using 2 polytetrafluoroethylene tube grafts: one for unifocalization and other as a bicuspid valved right ventricle-to-pulmonary artery conduit.

42. Primary Arterial Switch Operation for TGA/IVS and Regressed Left Ventricle: How and When to Use Left Ventricular Assist Device

Author

Malankar, Dhananjay P., Patil, Sachin, Mali, Shivaji, Dhake, Shyam, Mhatre, Amit, Bind, Dilip, Soni, Bharat, Kandavel, Dinesh, and Garekar, Swati

Abstract

Purpose: Numerous attempts have been made to extend the boundaries of arterial switch operation (ASO) in children presenting late with transposition of great arteries with intact ventricular septum (TGA/IVS) and regressed left ventricle (rLV). Many children tolerate the delayed ASO uneventfully, whereas others need mechanical circulatory support (MCS) to sustain the systemic circulation while the left ventricle undergoes retraining.Description: In this article, we describe six consecutive children with TGA/IVS and rLV who underwent primary ASO.Results: Three were managed medically, while three required MCS in the form of Centrimag left ventricular assist device (LVAD). All patients survived the operation and were discharged home in a stable condition.Conclusions: Primary ASO can be safely performed in children with TGA/IVS and rLV, provided the center has MCS options. Supporting the rLV with LVAD is feasible and can be achieved safely.

Abstract

Background:Excellent outcomes of right ventricle to pulmonary artery conduits with polytetrafluoroethylene (PTFE) valves have been reported. The purpose of this study was to analyze the short-term results of our handmade PTFE bicuspid valved conduit (VC) for right ventricular outflow tract reconstruction. Methods:Between September 2019 and May 2023, bicuspid PTFE-VC was implanted in 17 patients at a median age of 2.5 years (range, 3 months to 13.6 years). The PTFE-VC was fashioned from a commercially available PTFE tube graft (14 mm in three patients, 16 mm in three patients, 18 mm in one patient, 20 mm in three patients, and 22 mm in seven patients) and 0.1 mm thick PTFE membrane for the leaflet material. Valve function was assessed by echocardiogram after the implantation. The conduit reoperation and the conduit dysfunction were analyzed. There were no early deaths, but there was one late death. Results:There were no postoperative in-hospital deaths. Follow-up echocardiograms were available for 14 of 17 patients. The median follow-up was 21 months (range, 7-49 months). Conduit stenosis was none or trivial in 11 patients while it was mild in two and moderate in one patient and severe in 0 patients. Conduit insufficiency was mild or trivial in all 14 patients. By the end of the study period, freedom from reoperation/reintervention was 100%. There were no episodes of aneurysmal dilatation of the conduit or endocarditis. Conclusions:Handmade bicuspid PTFE VC shows good short-term outcome, with no significant valve dysfunction and no reintervention. A longer follow-up is necessary to evaluate the long-term advantages of using the handmade bicuspid PTFE VC.

Abstract

Background : We report a multiinstitutional study on intermediate-term outcome of intravascular stenting for treatment of coarctation of the aorta using integrated arch imaging (IAI) techniques. Methods and Results : Medical records of 578 patients from 17 institutions were reviewed. A total of 588 procedures were performed between May 1989 and Aug 2005. About 27% (160/588) procedures were followed up by further IAI of their aorta (MRI/CT/repeat cardiac catheterization) after initial stent procedures. Abnormal imaging studies included: the presence of dissection or aneurysm formation, stent fracture, or the presence of reobstruction within the stent (instent restenosis or significant intimal build-up within the stent). Forty-one abnormal imaging studies were reported in the intermediate follow-up at median 12 months (0.5–92 months). Smaller postintervention of the aorta (CoA) diameter and an increased persistent systolic pressure gradient were associated with encountering abnormal follow-up imaging studies. Aortic wall abnormalities included dissections ( n = 5) and aneurysm ( n = 13). The risk of encountering aortic wall abnormalities increased with larger percent increase in CoA diameter poststent implant, increasing balloon/coarc ratio, and performing prestent angioplasty. Stent restenosis was observed in 5/6 parts encountering stent fracture and neointimal buildup ( n = 16). Small CoA diameter poststent implant and increased poststent residual pressure gradient increased the likelihood of encountering instent restenosis at intermediate follow-up. Conclusions : Abnormalities were observed at intermediate follow-up following IS placement for treatment of native and recurrent coarctation of the aorta. Not exceeding a balloon:coarctation ratio of 3.5 and avoidance of prestent angioplasty decreased the likelihood of encountering an abnormal follow-up imaging study in patients undergoing intravascular stent placement for the treatment of coarctation of the aorta.

Abstract

Objective : To determine the complication rate during the catheterization in adults with congenital heart disease (CHD) in a pediatric catheterization laboratory (PCL). Background : An increasing number of patients with CHD are surviving into adulthood, with diagnostic and interventional cardiac catheterization being essential for the management of their disease. The complication rate during the catheterization of adults with CHD has not been reported. Methods : A retrospective chart review was performed on all adult patients (>18 years) with CHD who underwent diagnostic or interventional catheterization in our PCL within the past 8.5 years. Results : A total of 576 procedures were performed on 436 adult patients (median age 26 years). Complex heart disease was present in 387/576 (67%) procedures. An isolated atrial septal defect or patent foramen ovale was present in 115/576 (20%) procedures, and 51/576 (9%) procedures were performed on patients with structurally normal hearts with arrhythmias. Interventional catheterization was performed in 378/576 (66%) procedures. There were complications during 61/576 (10.6%) procedures; 19 were considered major and 42 minor. Major complications were death (1), ventricular fibrillation (1), hypotension requiring inotropes (7), atrial flutter (3), retroperitoneal hematoma, pneumothorax, hemothorax, aortic dissection, renal failure, myocardial ischemia and stent malposition (1 each). The most common minor complications were vascular entry site hematomas and hypotension not requiring inotropes. Procedures performed on patients ≥ 45 years of age had a 19% occurrence of complications overall compared with 9% occurrence rate in patients of age < 45 years ( P < 0.01). Conclusions : The complication rate during the catheterization of adults with CHD in a PCL is similar to the complication rate of children with CHD undergoing cardiac catheterization. The older subset of patients are more likely to encounter complications overall. The en
