Pulmonary vein stenosis

Pulmonary vein stenosis continues to pose significant challenges in children, frequently requiring repeated cardiac catheterisation procedures. This report describes a successful application of a "triple kissing balloon" technique to treat complex pulmonary vein stenosis in two patients, all accomplished with the use of a single 6-French sheath.

BACKGROUND: Centrally inserted central catheters (CICCs) are indispensable in modern healthcare, but unfortunately, come with complications. Catheter-related thrombosis is a well-known complication reported to occur in 5-30% of patients with CICC. There is a paucity of studies that report the incidence of catheter-related thrombosis after the introduction of real-time ultrasound insertion guidance as clinical practice. This study aimed to demonstrate any pathological macro- or microscopic changes in the vein wall associated with CICCs...

BACKGROUND: Peripherally inserted central catheters (PICCs) are the most common route of intravenous (I.V.) access for treatment of cystic fibrosis (CF) pulmonary exacerbations, but repeated PICC placement can result in upper extremity peripheral venous stenosis. Once peripheral stenosis develops, a non-cuffed tunneled central venous catheter (NcTCVC) is an alternative route for IV access. While these are regularly used at some CF centers, the safety and complication rate compared to PICCs in adults with CF has not been reported...

AIMS: Pulsed field ablation (PFA) is emerging as a nonthermal, tissue-specific technique for pulmonary vein isolation (PVI) in atrial fibrillation therapy. This preclinical study aimed to investigate the feasibility and safety of PVI using a novel PFA system including a nanosecond-scale PFA generator, a novel lotos PFA catheter, and a customized 12-French steerable sheath. METHODS AND RESULTS: A total of 11 Yorkshire swine were included in this study, with 4 in the acute cohort and 7 in the chronic cohort...

BACKGROUND: Pulsed field ablation (PFA) is a newer ablation energy source with the potential to reduce complications and improve efficacy compared to conventional thermal atrial fibrillation (AF) ablation. This study aimed to present an initial single-centre Australian experience of PFA for AF ablation. METHODS: Initial consecutive patients undergoing PFA for paroxysmal or persistent AF at a single centre were included. Baseline patient characteristics, procedural data and clinical outcomes were collected prospectively at the time of the procedure...

We encountered acute pulmonary vein (PV) stenosis during radiofrequency catheter ablation. PV stenosis was not apparent before redo ablation (A). However, acute PV stenosis was observed after repeat ablation, including carina ablation (B, C). Computed tomography performed 6 months post-ablation revealed chronic PV stenosis (D).

Anesthesia management of fetal pulmonary valvuloplasty (FPV) is difficult, requiring careful consideration of both the mother and the fetus. Few reports have been published on specific anesthesia implementation and intraoperative management. We report the case of a pregnant woman who was treated with FPV under combined spinal epidural anesthesia (CSEA) with dexmedetomidine in the second trimester of pregnancy. Meanwhile, the application of fetal anesthesia through the umbilical vein was optimal. During the operation, the vital signs of the pregnant woman were stable with no complications and the fetal bradycardia was corrected by intracardiac injection of epinephrine...

IMPORTANCE: In treating atrial fibrillation, pulsed field ablation (PFA) is a novel energy modality with comparable efficacy to conventional thermal ablation, such as radiofrequency ablation (RFA), but with the benefit of some preferentiality to myocardial tissue ablation. Studies have demonstrated important safety advantages, including the absence of esophageal injury or pulmonary vein stenosis and only rare phrenic nerve injury. However, there is emerging evidence of coronary artery vasospasm provoked by PFA...

A 65-day-old girl presented to the emergency room with lethargy, requiring emergency venoarterial extracorporeal membrane oxygenation for refractory cardiogenic shock. Initially, hypoplastic left heart syndrome was suspected. However, cor triatriatum with a pinpoint opening on the membrane was diagnosed based on a detailed echocardiographic examination. After membrane resection, the left heart size was restored. However, follow-up echocardiography performed 4 months later showed occlusion of both upper pulmonary veins and stenosis in both lower pulmonary veins...

A 6-year-old boy with a case of double outlet right ventricle with large non-routable ventricle septal defect and severe pulmonary stenosis was deemed unsuitable for biventricular repair on a prior evaluation. Hence, a bidirectional Glenn (BDG) shunt was performed at 3 years of age following cardiac catheterization.

• A continuous antegrade wave is seen in both PVS and large left-to-right shunts. • Color turbulence in pulmonary veins is overlooked in large left-to-right shunts. • PISA can be used to diagnose PVS.

Pectus excavatum (PE) is often associated with scoliosis and can elicit cardiovascular disturbances under rare conditions. Here we report a patient who was treated with a combined Ravitch and Nuss procedure for PE with dyspnea following scoliosis repair to improve her symptoms. The patient was a 49-year-old woman with a history of PE and scoliosis. Right inferior pulmonary vein stenosis was caused by posterior spinal fusion for scoliosis prior to the PE repair. We could safely correct the chest wall deformity and treat dyspnea by performing a modified Ravitch repair in combination with the Nuss procedure...

Vascular complications are commonly associated with COVID-19 infection. Increasing reports suggest a close relationship between COVID-19 and venous thromboembolic diseases, including deep vein thrombosis and pulmonary embolism. Furthermore, COVID-19 has been linked to various aortic diseases such as aortic valve stenosis, aortic thrombosis, abdominal aortic aneurysm, aortic dissection, and limb ischemia. Consequently, understanding the causes and treatment of these vascular complications has become a critical aspect of comprehensive COVID-19 management...

BACKGROUND: Pulmonary vein stenosis (PVS) is a rare pediatric condition associated with significant mortality and morbidity. PVS in patients following heart transplant (HT) has not yet been described. METHODS: Patients who had clinically significant PVS following a heart transplant during the time period of April 1, 2013 to April 30, 2023, at Seattle Children's Hospital were identified. Clinically significant PVS was defined as an atretic vein or a vein with a gradient of ≥4 mmHg across at least one vein by echocardiogram or during cardiac catheterization...

UNLABELLED: Lutembacher's syndrome is a rare disease defined as the combination of atrial septal defect and mitral stenosis, which relieves the progression of symptoms resulting from mitral stenosis. We present a case of a previously asymptomatic 70-year-old man having Lutembacher's syndrome with sinus venosus type of interatrial defect associated with partial anomalous pulmonary venous drainage. Our patient's only complaint was of mild exertional dyspnea, which started six months prior to referral...

Pulmonary vein stenosis (PVS) is a condition that has seen a decrease in incidence in recent years. Whereas balloon angioplasty and stenting are both acceptable treatment options for PVS, they are limited by the high rate of restenosis. This research paper presents 4 cases of severe symptomatic PVS that were successfully treated with the use of drug-coated balloons, resulting in positive outcomes. (Level of Difficulty: Advanced.) .
