Branch pulmonary artery stenosis is one of the most common complications late after the arterial switch operation. The pathophysiology of stenosis in these circumstances is very different to that encountered in with normally related great vessels. The LeCompte manoeuvre leaves the pulmonary arteries straddled and stretched over the aortic root which contributing significantly to the degree of stenosis encountered. Unilateral branch pulmonary artery stenosis rarely leads to significant symptoms in young patients with biventricular repairs; however, significant discrepancies in the split flows between right and left lung may place the patient in an unfavourable physiological position as they move in to middle age...

Isolation areas post-28-mm cryoballoon pulmonary vein isolation (CB-PVI) are smaller than post-radiofrequency PV antrum isolation at the left superior PV (LSPV) antrum and recurrent atrial fibrillation (AF) can originate from this area. This pilot study evaluated the impact of additional extra-PV CB applications at the LSPV antrum following conventional CB-PVI. Eighteen paroxysmal AF patients underwent CB-PVI with single 3-min freeze techniques. Following the CB-PVI, 2-min CB applications were added once or twice at the LSPV antrum...

A 17-year-old girl with situs ambiguous, hypoplastic right ventricle with a large ventricular septal defect, and severe pulmonary stenosis had undergone Kawashima operation 10 years back. She had significant desaturation because of a large Abernethy malformation, with reverse shunting from the inferior caval vein to the portal vein. It was closed with a vascular plug, with improvement in oxygen saturation. She developed extensive inferior caval vein thrombus following the procedure, which was managed conservatively by anti-coagulation...

An elderly male patient with coronary heart disease underwent coronary angiography, which revealed bilateral severe coronary artery stenosis. Four stents were implanted, and at 5 h post-surgery, typical hemorrhagic shock appeared. Echocardiography verified heavy bleeding in the right thoracic cavity. Emergency angiography excluded injury or perforation of the coronary artery, aorta, right subclavian artery and brachiocephalic artery. Considering the patient's history of chronic obstructive pulmonary disease and severe cough during the operation, it was suspected that hemothorax was induced by a blood vessel rupture in the pleura...

This article reviews important features to improve the diagnosis of congenital heart disease (CHD) by applying ultrasound in prenatal cardiac screening. As low and high-risk pregnancies for CHD are subject to routine obstetric ultrasound, the diagnosis of structural heart defects represents a challenge that involves a team of specialists and subspecialists on fetal ultrasonography. In this review, the images highlight normal anatomy of the heart as well as pathologic cases consistent with cardiac malposition and isomerism, septal defects, pulmonary stenosis/atresia, aortic malformations, hypoplastic left ventricle, conotruncal anomalies, tricuspid dysplasia, and Ebstein's anomaly, and univentricular heart, among other congenital cardiovascular defects...

BACKGROUND CONTEXT: Postoperative Urinary Retention (POUR) is a very common post-operative complication of all surgeries (5 - 70%) that may lead to complications such as urinary tract infection (UTI), bladder over-distention, autonomic dysregulation, and increased postoperative length of stay (LOS). Within the field of spine surgery, the reported incidence of POUR is highly variable (5.6 - 38%). Lack of clear stratification of surgical level, spinal pathology, and inadequate sample size is a major limitation of available studies concerning POUR following spine surgery that may lead to inconsistency in the incidence of POUR and the ability to model its occurrence and consequences...

Aims: Results of catheter based interventional treatment for pulmonary vein stenosis (PVS) following radiofrequency ablation (RFA) for atrial fibrillation remain suboptimal. Surgical repair may represent an alternative therapy, though long-term results have not been thoroughly investigated. Methods and results: We retrospectively assessed all patients in our centre undergoing surgical repair for radiofrequency-induced PVS. Data regarding surgical technique, clinical outcome, and rate of pulmonary vein (PV) restenosis were collected and analysed...

Sinus of Valsalva (SV) rupture is a rare, cardiac complication after surgical repair of complex congenital heart disease. This paper reports a 4-year-old male child with double outlet right ventricle (RV) and pulmonary stenosis with superior-inferior arrangement of the ventricles, who was submitted to surgical repair using the "reparation a l'etage ventriculaire" procedure. A few months after an uneventful surgical repair, his clinical condition abruptly worsened because of the rupture of the right SV into the RV outflow tract resulting in large left-to-right shunt and RV functional impairment...

Surgical repair of total anomalous pulmonary venous connection (TAPVC) can be complicated by the development of pulmonary venous stenosis later on. In addition, the vertical vein, if left unligated, can remain patent and lead to hemodynamically significant left to right shunting. We report an infant who required transcatheter correction of both these problems after surgical repair of TAPVC.

Aortic stenosis (AS) is the most common type of valvular heart disease in the elderly. Surgical aortic valve replacement (SAVR) has been the standard practice for treating severe, symptomatic AS, but recently new treatment options have emerged. Transcatheter aortic valve replacement (TAVR) is now an established treatment option in patients at high surgical risk. In this review, we focus on recent developments and compare the two treatment methods in specific populations in terms of efficacy and safety (e.g...

Right ventricular outflow tract (RVOT) dysfunction is a common hemodynamic challenge for adults with congenital heart disease (ACHD), including patients with repaired tetralogy of Fallot (TOF), truncus arteriosus (TA), and those who have undergone the Ross procedure for congenital aortic stenosis and the Rastelli repair for transposition of great vessels. Pulmonary valve replacement (PVR) has become one of the most common procedures performed for ACHD patients. Areas covered: Given the advances in transcatheter technology, we conducted a detailed review of the available studies addressing the indications for PVR, historical background, evolving technology, procedural aspects, and the future direction, with an emphasis on ACHD patients...

We present a very rare case of isolated right pulmonary veins atresia in a 4-year-old girl. As the presence of a pulsatile blind pulmonary venous confluence adjacent to the left atrium was demonstrated by preoperative right pulmonary arterial wedge angiography, we applied sutureless pericardial marsupialization for the repair of right pulmonary veins atresia. She is currently 8 years old without pulmonary veins stenosis.
