Project description:Leadless pacemakers have many advantages for some patients in preventing lead- and pocket-related complications. The traveling of the femoral vein is important in the context of normal approach site choice for leadless pacemakers. In this case, the leadless pacemaker could be successfully implanted without disrupting the inferior vena cava filter by using intravascular ultrasound in a hemodialysis patient with complete atrioventricular block and atrial fibrillation who had obstruction of the bilateral subclavian and right femoral veins, and travel abnormality of the left common iliac vein. <Learning objective: The leadless pacemaker is a useful option in patients with complex vascular complications and hemodialysis. However, there are several listed contraindications such as the presence of inferior vena cava (IVC) filter that was excluded in the large-scale trials to leadless pacemakers. Intravascular ultrasound is a useful tool to place the leadless pacemaker without disrupting IVC filter to maintain its filtering capability.>.

Project description:BackgroundCongenital absence of superior vena cava (CASVC) is an extremely rare vascular anomaly often associated with conduction disturbances which makes implantation of a pacemaker difficult. We report a case of pacemaker implantation in a patient presenting with complete atrioventricular block (c-AVB) with bilateral absence of the SVC.Case summaryA 68-year-old man who had experienced dyspnoea on exertion by c-AVB was admitted to our hospital for treatment and management. Permanent pacemaker insertion was initially planned; however, an endocardial pacemaker lead could not be implanted in the right atrium. Computed tomography scan with contrast revealed that the venous blood from the upper half of the body flowed into the inferior vena cava via the azygos vein. Due to the difficulty of inserting an endocardial lead from the subclavian vein, a leadless pacemaker (LP) was implanted instead via the femoral vein.DiscussionThis is the first case of an LP implantation in a patient presenting with c-AVB with CASVC. Confirmation of blood vessel anatomy to rule out CASVC is necessary prior to pacemaker implantation when abnormal venous anatomy is suspected.

Project description:Persistent left superior vena cava (PLSVC) is a rare disorder which is asymptomatic and hence is usually discovered while performing interventions through the left subclavian vein. We present a case of a 78-year-old male who was undergoing elective placement of a permanent pacemaker for tachycardia - bradycardia syndrome with post-conversion pauses of up to nine seconds. After achieving access through the left subclavian vein the wire kept on going on the left side of the chest instead of crossing the midline to the right side. The wire was removed and contrast venography was done, PLSVC with dilated coronary sinus emptying into the right atrium was confirmed. There was some difficulty in passing the lead to the right ventricle even with the acute curve in the stylet. The sheath size was increased and a longer deflectable sheath was used and with the tip of the lead anteriorly the right ventricle was cannulated and the lead was affixed. There were good sensing and pacing parameters. Post procedure chest x-ray was done and the patient was discharged without any complications.

Project description:Superior vena cava (SVC) syndrome is an uncommon but serious complication associated with chronic transvenous implanted leads. In the recent past, open-heart surgery combining lead extraction and epicardial implant was usually performed to reduce syndrome recurrences. We describe the case of a 78-year-old man successfully treated by percutaneous lead extraction associated with venous balloon angioplasty and reimplantation of leadless pacemaker. <Learning objective: Chronic vascular complications following lead implantation usually require surgical treatment, due to the need for subsequent epicardial implantation. Percutaneous lead extraction along with leadless pacing allowed effective non-surgical management of chronic complications of transvenous pacing.>.

Project description:BackgroundDextrocardia, or right-lying heart, is an uncommon congenital heart disease in which the apex of the heart is located on the right side of chest. Persistent left superior vena cava (PLSVA) is a rare venous anomaly that is often associated with the abnormalities of cardiac transduction system. A case with combination of dextrocardia, persistent left superior vena cava, and sick sinus syndrome has not been reported.MethodsWe used different techniques including cardiac color Doppler echocardiography, 24-hour Holter monitoring, and abdominal ultrasound to make a diagnosis and treated the patient by implanting a VVI pacemaker.ResultsA 50-year-old woman was admitted with a syncope. Angiography of the right atrium and superior vena cava, echocardiography, electrocardiography, and abdominal ultrasound revealed the presence of the combination of mirror image dextrocardia, PLSVA, and sick sinus syndrome. The complex structural anomalies presented great technical challenges for interventional treatments. After thorough examination and understanding of the structural anatomy and anomalies of the superior and inferior vena cava and cardiac chambers, we successfully treated this patient by implanting a VVI pacemaker.ConclusionPhysicians must be aware of the complexity of the morphological and anatomical structures of dextrocardia accompanying PLSVC. Given that the diagnosis of situs inversus was performed at a relatively advanced age, it is therefore important to make such a correct diagnosis followed by appropriate therapeutic intervention.

Project description:Persistent left superior vena cava is the most common congenital anomaly of thoracic venous return, which results when the left anterior cardinal vein fails to regress. A 41-year-old African American male with a history of an unspecified childhood cardiac murmur presented to the emergency department with congestive heart failure exacerbation revealing an incidental finding of a persistent left superior vena cava. Ultimately, he required implantable cardioverter defibrillator placement and cardiac transplantation assessment. In the setting of advanced device placement or cardiac transplantation, a persistent left superior vena cava warrants several important clinical considerations at a center capable of addressing the possibility of a right-sided approach and transplantation irregularities.

Project description:The chylothorax is a lymphocyte predominant protein-discordant exudative pleural effusions with low lactate dehydrogenase and elevated triglyceride levels. Transudative chylothoraces associated with Superior Cava syndrome (SVC) are an extremely rare clinical entity. In this manuscript, we describe a case of transudative chylothorax due to SVC obstruction secondary to thrombosis of a peripheral inserted central venous catheter, which ultimately resolved after endovascular intervention. In our review of the literature, only five cases of transudative chylothorax associated with SVC syndrome were identified with 60% of cases associated with thrombosis and complications due to catheters in the central venous circulation. Treatment of the underlying cause is key to resolution of the chylothorax. Thoracentesis is an initial intervention for diagnostic and therapeutic purposes. Endovascular intervention is the primary mode of treatment for SVC thrombosis and stenting is preferred for malignant causes, however anticoagulation alone has been reported in the resolution of chylothorax. In patients with recurrent chylothorax despite of relief of SVC obstruction, a medium-chain triglyceride diet and octreotide can be prescribed in order to decrease the chyle flow in the thoracic duct. Surgical ligation of the thoracic duct can be considered if medical management and endovascular treatment fails.

Project description:Superior vena cava obstruction syndrome was studied in 22 patients with a view to assess the etiological pattern and clinical profile. It was found that 4 patients (18.1%) had benign disease and the remaining 18 (81.9%) patients had malignancy. In 13 patients (59.9%) obstruction occurred due to bronchogenic carinoma. No complications occurred with invasive diagnostic procedures. All heavy smokers (59.9%) were found to have malignancy. Normal lung fields on chest radiography and CT scan with superior vena obstruction syndrome suggested benign disease in 2 cases.
