BACKGROUND: Second-generation cryoballoon (CB2)-based pulmonary vein isolation (PVI) has demonstrated encouraging clinical results in the treatment of paroxysmal (PAF) and persistent atrial fibrillation (PersAF). However, the CB2 features a maximal diameter of 28 mm, and its adaptability to anatomic variations of the pulmonary veins (PVs) might be challenging. OBJECTIVE: The purpose of this study was to assess the acute efficacy, safety, and long-term clinical results of CB2-based PVI in patients with a left common pulmonary vein (LCPV)...

Aims: Procedure times and left atrial dwell times of cryoballoon (CB)-based ablation strategies for atrial fibrillation (AF) are shorter as compared to radiofrequency ablation, yet fluoroscopy times are longer and result in a higher radiation exposure. The objective of this study is to evaluate a modified fluoroscopy protocol aiming at reduction of radiation exposure in CB ablation. Methods: A total of 120 patients with symptomatic AF underwent pulmonary vein isolation (PVI) using the second generation CB and an ablation strategy considering the individual time-to-isolation...

A 62 year-old male with long-standing smoking history presented with hemoptysis. Plain chest x-ray showed abnormal findings proximate to the right pulmonary hilum. Bronchoscopy revealed a fragile exophytic tumor of the right wall of the lower third of the trachea, infiltrating the right main bronchus (75% stenosis) and the right upper lobar bronchus (near total occlusion). Contrast-enhanced chest CT demonstrated a 7.2x4.9 cm tumor contiguous to the above-mentioned structures, mediastinal lymph node pathology, and a vessel coursing inferiorly to the left of the aortic arch and anterior to the left hilum...

Primary intravascular synovial sarcoma is a rare malignancy with only a few cases documented in the literature. On presentation, this tumour usually resembles a deep venous thrombosis (dvt) or pulmonary embolism (pe). Here, we report the case of a 20-year-old woman complaining of shortness of breath who had a history of dvt 6 weeks before presentation at our institution. Vascular ultrasound detected a suspicious mass in the right groin, which was identified as a monophasic synovial sarcoma by surgical biopsy...

BACKGROUND: There are very limited prospective data on the significance of persistent antiphospholipid antibodies (aPL) and recurrent thrombo-occlusive events (TOEs). We investigated the prognostic value of (1) 2 newer aPL assays, (2) an aPL portfolio and (3) persistent aPL positivity following stroke. METHODS: A total of 1,770 subjects from the APASS-WARSS study underwent further aPL testing for antibodies to phosphatidylserine (aPS) and anti-β2-glycoprotein-I (anti-β2GPI) from stored sera...

Pulmonary vein (PV) stenosis (PVS) is a known complication of PV isolation procedures for AF (atrial fibrillation). PV angioplasty and stenting have been used as an effective therapy for PVS, yet high rates of restenosis are common. Experience with intravascular ultrasound (IVUS) in evaluating the PVS morphological characteristics and appropriate stent deployment is very limited. Furthermore, the use of IVUS could minimise the risk of restenosis. We describe the case of a patient with sub-occlusion of the left superior PV and total occlusion of the left inferior PV following catheter ablation for AF treated by stenting with IVUS guidance...

The authors carried out comparative assessment of efficacy of cava filters (CF) for prevention of pulmonary artery thromboembolism in patients presenting with iliofemoral thrombosis with flotation of thrombi, as well as analysed complications in the remote postimplantation period. A total of 266 patients were examined within the terms from 1 month to 10 years after CF implantation. Depending on the type of the implanted device, all patients were subdivided into 3 groups: group 1 (n=65) consisted of patients with one-level CF, group 2 (n=112) comprised those with "sandglass" and "shuttle" type two-level cava filters, and group 3 (n=89) was composed of patients with the implanted CF "TrapEase" and "OptEase"...

AIMS: Left atrial appendage (LAA) is the source of thrombi in up to 90% of patients with non-valvular atrial fibrillation (AF). Catheter ablation (CA) is an effective treatment for symptomatic AF and, in selected cases, LAA occlusion devices have been introduced as an alternative to oral anticoagulants (OACs). The safety and feasibility of combining CA and percutaneous LAA closure (LAAC) are unknown. METHODS AND RESULTS: Patients with symptomatic drug-refractory AF, CHADS2 score of ≥1, and CHA2DS2-VASc score ≥2 were included...

: The usual surgical practice after repair of a Total Anomalous Pulmonary Venous Connection (TAPVC) is to ligate the vertical vein (VV). Many surgeons find it expedient to leave the VV unligated to reduce pulmonary arterial pressure, decrease perioperative pulmonary hypertensive crisis, provide better hemodynamics postoperatively (1), and enable the adaptation of cardiac chambers to a new workload. Afterwards, the unligated VV may cause significant left-to-right shunt, likewise an atrial septal defect, mandating later surgical ligation or device closure (2)...

Varicose veins, associated with great saphenous vein (GSV) incompetence, are traditionally treated with conventional surgery. In recent years, minimally invasive alternatives to surgical treatment such as the endovenous laser ablation (EVLA) and radiofrequency (RF) ablation have been developed with promising results. Residual varicose veins following EVLA, regress untouched, or phlebectomy or foam sclerotherapy can be concomitantly performed. The aim of the present study was to investigate the safety and efficacy of EVLA with different levels of laser energy in patients with varicose veins secondary to saphenous vein reflux...

Pulmonary vein stenosis occurs in 1.3% of patients undergoing pulmonary vein isolation procedures for atrial fibrillation. Complete occlusion can occur and is often associated with symptoms including dyspnea and chest pain. Percutaneous intervention with angioplasty and stenting is frequently performed for pulmonary vein stenosis, but management of pulmonary vein occlusion remains challenging. We report the case of a 47-year-old female who presented with dyspnea and history of two previous radiofrequency ablation procedures for paroxysmal atrial fibrillation...
