Unpredicted sudden death arising from hemangiopericytoma with massive intracranial hemorrhage is quite rare. We encountered a patient with recurrent infratentorial hemangiopericytoma presenting as life-threatening massive intracerebral hemorrhage. A 43-year-old man who had undergone craniotomy for total resection of an infratentorial hemangiopericytoma 17 months earlier presented with morning headache and generalized convulsions. Computed tomography revealed a massive hematoma in the right infratentorial region causing tonsillar herniation and emergency surgery was performed to evacuate the hematoma. Histological findings revealed hemangiopericytoma with hemorrhage. Neurological status remained unimproved and brain death was confirmed postoperatively. Hemangiopericytoma presenting as massive hemorrhage is quite rare. Since the risk of life-threatening massive hemorrhage should be considered, careful postoperative long-term follow-up is very important to identify tumor recurrences, particularly in the posterior cranial fossa, even if the tumor is completely removed.

Anatomy and physiology are the basis of human body functioning and as we have progressed in management of various diseases, we have understood that physiological intervention is always better than an anatomical one. For more than 50 years, a standard approach to permanent cardiac pacing has been an anatomical placement of transvenous pacing lead at the right ventricular apex with a proven benefit of restoring the rhythm. However, the resultant ventricular dyssynchrony on the long-term follow-up in patients requiring more than 40% ventricular pacing led to untoward side effects in the form of heart failure and arrhythmias. To counter such adverse side effects, a need for physiological cardiac pacing wherein the electrical impulse be transmitted directly through the normal conduction system was sought. His bundle pacing (HBP) with an intriguing alternative of left bundle branch pacing (LBBP) is aimed at restoring such physiological activation of ventricles. HBP is safe, efficacious, and feasible; however, localization and placement of a pacing lead at the His bundle is challenging with existing transvenous systems due to its small anatomic size, surrounding fibrous tissue, long-learning curve, and the concern remains about lead dislodgement and progressive electrical block distal to the HBP lead. In this article, we aim to take the reader through the challenging journey of HBP with focus upon the hardware and technique, selective versus nonselective HBP, indications and potential disadvantages, and finally the future prospects.

This study reviewed the short-term outcome of transcatheter closure of the defects within the oval fossa using an Amplatzer® Septal Occluder. From January 1997 to December 2000, 210 patients with defects within the oval fossa underwent successful transcatheter closure. We reviewed a total of 190 patients with left-to-right shunts, assessing the patients for possible complications and the presence of residual shunts using transthoracic echocardiogram at 24 h, 1 month, 3 months and one year. Their median age was 10 years, with a range from 2 to 64 years, and their median weight was 23.9 kg, with a range from 8.9 to 79 kg. In 5 patients, a patent arterial duct was closed, and in 2 pulmonary balloon valvoplasty performed, at the same sitting. The median size of the Amplatzer® device used was 20 mm, with a range from 9 to 36 mm. The median times for the procedure and fluoroscopy were 95 min, with a range from 30 to 210 min, and 18.4 min, with a range from 5 to 144 min, respectively. Mean follow-up was 20.8 ± 12.4 months. Complete occlusion was obtained in 168 of 190 (88%) patients at 24 h, 128 of 133 (96.2%) at 3 months, and 103 of 104 (99%) at one year. Complications occurred in 4 (2.1%) patients. In one, the device became detached, in the second the device embolized into the right ventricular outflow tract, the lower end of the device straddled in the third, and the final patient had significant bleeding from the site of venupuncture. There were no major complications noted on follow-up. We conclude that transcatheter closure of defects within the oval fossa using the Amplatzer® Septal Occluder is safe and effective. Long-term follow-up is required, nonetheless, before it is recommended as a standard procedure.

Apical Aneurysm

Background: Increasing penetration of high spatial resolution cardiovascular magnetic resonance (CMR) imaging into routine cardiovascular practice has resulted in more frequent identification of a subset of hypertrophic cardiomyopathy (HCM) patients with thin-walled, scarred left ventricular (LV) apical aneurysms. Prior experience involved relatively small numbers of patients with short follow-up and therefore the risk associated with this subgroup remains incompletely defined. Therefore, we assembled a large HCM cohort with LV apical aneurysms and long-term follow-up in order to clarify clinical course and prognosis. Methods and Results: Of 2,400 HCM patients, 60 (2.5%) were identified by CMR with LV apical aneurysm, 24 to 86 years of age, including 19 (32%) <45 years old; 70% male, and followed for 5.6 ± 3.5 years. Over the follow-up period, 24 patients experienced 31 adverse disease-related complications including: appropriate implantable cardioverter-defibrillator discharge for VT/VF (n=11), received or listed for heart transplant (n=6), heart failure death (n=5), nonfatal thromboembolic events (n=4), resuscitated out-of-hospital cardiac arrest (n=3), and sudden death (n=2). In addition, an intracavitary thrombus was identified in the apical aneurysm in 9 patients without a thromboembolic history. Combined HCM-related death and aborted life threatening event rate was 8.6% per year, nearly 6-fold greater than the 1.5% annual mortality rate reported in the general HCM population. Conclusions: Patients with LV apical aneurysms represent a high-risk subgroup within the diverse HCM spectrum, associated with substantial increased risk for disease-related morbidity and mortality, including advanced heart failure, thromboembolic stroke and sudden death. Identification of this unique HCM phenotype should prompt consideration for primary prevention ICD, and anticoagulation for stroke prophylaxis.

AbstractObjective:Double-chambered right ventricle is characterised by division of the outlet portion of the right ventricle by hypertrophy of the septoparietal trabeculations into two parts. We aim to report our experiences regarding the presenting symptoms of double-chambered right ventricle, long-term prognosis, including the recurrence rate and incidence of arrhythmias after surgery.Methods:We retrospectively investigated 89 consecutive patients who were diagnosed to have double-chambered right ventricle and underwent a surgical intervention from 1995 to 2016. The data obtained by echocardiography, cardiac catheterisation, and surgical findings as well as post-operative follow-up, surgical approaches, post-operative morbidity, mortality, and cardiac events were evaluated.Results:Median age at the time of diagnosis was 2 months and mean age at the time of operation was 5.3 years. Concomitant cardiac anomalies were as follows: perimembranous ventricular septal defect (78 patients), atrial septal defect (9 patients), discrete subaortic membrane (32 patients), right aortic arch (3 patients), aortic valve prolapse and/or mild aortic regurgitation (14 patients), and left superior caval vein (2 patients). The mean follow-up period was 4.86 ± 4.6 years. In these patients, mean systolic pressure gradient in the right ventricle by echocardiography before, immediately, and long-term after surgical intervention was 66.3, 11.8, and 10.4 mmHg, respectively. There were no deaths during the long-term follow-up period. Surgical reinterventions were performed for residual ventricular septal defect (2), residual pulmonary stenosis (1), and severe tricuspid insufficiency (1).Conclusion:The surgical outcomes and prognosis of double-chambered right ventricle are favourable, recurrence and fatal arrhythmias are unlikely in long-term follow-up.

Abstract An aorto-esophageal fistula (AEF) is a rare yet life-threatening cause of upper gastrointestinal bleeding. We report our experience with open surgical management of two cases of AEF. Both cases presented with almost identical presentations: hematemesis and hemodynamic instability. The aorta in the first patient was normal; the defect was small and was repaired with a Dacron patch. The second patient had an aneurysmal aorta, which was replaced with a Dacron graft. Both cases were performed under partial bypass. The esophageal rent in both patients was debrided, primarily closed and buttressed with a vascularized intercostal pedicle. Nonavailability of endovascular personnel and equipment along with hemodynamic instability of the patient influenced our surgical strategy. Long-term follow-up of these patients is necessary to analyze the outcomes of our surgical repair.

“Carotid blowout syndrome” is defined as a hemorrhage caused by rupture of the carotid artery and its branches, and may be a severe complication of rhinopharyngeal carcinoma. This study aimed to highlight the usefulness and versatility of endovascular stent-graft placement as a rescue treatment in life-threatening carotid blowout syndrome. We describe the unconventional use of a 6×5 mm balloon-expandable coronaric covered stent in a patient with a diagnosis of spinocellular rhinopharyngeal carcinoma, followed by carotid blowout syndrome. Although long-term follow-up is needed to assess the eventuality of bleeding recurrence, the immediate clinical results were satisfactory.
