Persistent left superior caval vein draining into right atrium, but not through the coronary sinus.

Project description:Persistence of the left superior caval vein is the most commonly reported thoracic venous anomaly. The vein usually drains into the right atrium through the coronary sinus, reflecting its developmental origin. We describe an unusual variant, in which the vein drained directly into the right atrium.

Acute Thrombosis of Left Portal Vein during Right Portal Vein Embolization Extended to Segment 4.

Project description:Portal vein thrombosis (PVT) is an uncommon, but potentially devastating complication of portal vein embolization (PVE). Its occurrence relates to both local and systemic risk factors. In the setting of PVE, precipitating factors include injury to the vessel wall and reduced portal flow. Contributory factors include portal hypertension, hypercoagulopathy, inflammatory processes, malignancy, pregnancy, oral contraceptive use, and asplenia. The goal of therapy is to prevent thrombus progression and lyse existing clot. Hepatectomy is impossible if adequate recanalization has not occurred and/or overt portal hypertension develops. The mechanisms for thrombus development, its diagnosis, management, and prognosis are discussed.

Efficacy of Local Treatments for Hepatocellular Carcinoma Involving the Inferior Vena Cava and/or Right Atrium.

Project description:Major vessel invasion is frequently observed in locally advanced hepatocellular carcinoma (HCC). The most commonly involved major vessel is the portal vein; however, approximately 4% of patients with HCC have inferior vena cava (IVC) and/or right atrium (RA) invasion. Although these conditions have dismal prognoses, local treatments have not been regularly administered because they may affect systemic circulation. Owing to recent technological advances, various local treatments including surgery and external radiotherapy have increasingly been performed in these patients. Since irradiating tumorous lesions in the liver while preserving normal tissues is possible and major vessels are relatively resistant to radiation, external radiotherapy has been a feasible palliative modality for treating vessel-invasive HCC. In addition, systemic fatal complications that were initially a cause of concern have become rare after radiotherapy. While invasive procedures such as extracorporeal circulation or hepatic vascular exclusion may be required, pioneering surgeons have performed surgical resections in selected patients and have obtained promising results. Surgery has shown the best survival outcomes compared to other treatment options including radiotherapy, but the possibility of perioperative morbidity should be considered. In addition, a combination of local treatment and novel systemic agents, which demonstrated better survival and response rates than sorafenib, is expected to maximize therapeutic effects. In this review, we have discussed the most recent treatments for HCC with IVC and/or RA involvement and have provided information intended to guide therapeutic decisions and facilitate future research.

Successful Treatment of a Stenotic Pulmonary Vein to Left Atrium Conduit With a Drug-Eluting Stent.

Project description:Partial anomaly of the pulmonary venous return is a rare congenital condition treated with surgical redirection of the blood flow through the creation of a conduit to the left atrium. We report the case of a stenotic pulmonary vein to left atrium conduit successfully treated with the implantation of a drug-eluting stent. Pulmonary vein or conduit stenosis is generally treated with balloon dilation or bare-metal stent but is often met with underwhelming outcomes. Given the successful outcome of the case presented, drug-eluting stents may represent an attractive treatment option in suitable anatomies.

Non-Pulmonary Vein Triggers of Atrial Fibrillation Are Likely to Arise from Low-Voltage Areas in the Left Atrium.

Project description:The pathophysiology of non-pulmonary vein (PV) triggers of atrial fibrillation (AF) is unclear. We hypothesized that left atrial non-PV (LANPV) triggers are associated with atrial tissue degeneration. This study analyzed 431 patients that underwent catheter ablation (mean age 62?yrs, 303 men, 255 paroxysmal AF [pAF] patients). Clinical and electrophysiological characteristics of non-PV trigger were analyzed. Fifty non-PV triggers in 40 patients (9.3%) were documented; LANPV triggers were the most prevalent (n?=?19, 38%). LANPV triggers were correlated with non-paroxysmal AF (non-pAF) (OR 3.31, p?=?0.04) whereas right atrial non-PV (RANPV) triggers (n?=?14) and SVC triggers (n?=?17) were not. The voltage at the LANPV sites during SR was 0.3?±?0.16?mV (p?<?0.001 vs. control site). Low-voltage areas (LVAs) in the LA were significantly greater in non-pAF compared to pAF (14.2% vs. 5.8%, p?<?0.01). RANPV trigger sites had preserved voltage (0.74?±?0.48?mV). Long-term outcomes of patients with non-PV triggers treated with tailored targeting strategies were not significantly inferior to those without non-PV triggers. In conclusion, non-PV triggers arise from the LA with degeneration, which may have an important role in AF persistence. A trigger-oriented, patient-tailored ablation strategy considering LA voltage map may be feasible and effective in persistent/recurrent AF.
