Richard Bloomingdale, Said Ashraf, Shaun Cardozo
Isolated atrial septal defect (ASD) accounts for 13% of congenital heart disorders. The anatomic location, size, and coexistence of other cardiac anomalies determine outcomes of repair. Surgical closure was the first-choice treatment until the 1990s and remains the only treatment for large defects. We describe a case of a 64-year-old woman who underwent surgical repair for an ASD as a child in 1959. She presented with dyspnea to the hospital almost 53 years after the surgery. Diagnostic cardiac imaging revealed interesting anatomy of the repair surgery...

INTRODUCTION: Two leadless pacemaker (PM) systems were recently developed to avoid pocket- and lead-related complications. As leadless PMs are implanted with a large delivery catheter, cardiac perforation remains a major safety concern. We aimed to provide a literature review on incidence of cardiac perforation with conventional and with leadless PM systems. METHODS AND RESULTS: A systematic review over the last 25 years for studies reporting data on PM lead perforation was performed...

BACKGROUND: Transesophageal echocardiography is widely used in cardiac surgery. Transesophageal echocardiography probe insertion and manipulation can injure the esophagus. CASE PRESENTATION: A 76-year-old Asian man was admitted to our hospital for coronary artery bypass graft revascularization surgery. A right carotid endarterectomy was successfully performed 2 days before coronary artery bypass graft revascularization surgery. After the coronary artery bypass graft revascularization surgery was done successfully, postoperative computed tomography and esophagography revealed perforation of the middle esophagus...

BACKGROUND: Only a few studies have reported treatment options for stenosis after endoscopic submucosal dissection (ESD) for gastric neoplasms. This study aimed to identify the risk factors for and evaluate the management of stenosis after ESD for gastric epithelial neoplasms in the cardia and antrum. METHODS: We retrospectively reviewed 1218 patients (1447 gastric epithelial neoplasms) who underwent ESD at Tonan Hospital from June 2004 to November 2015. Post-ESD stenosis was defined when a standard endoscope could not be passed through the site...

A 45-year-old male, an alcohol addict with asthma, was found dead in his home, after several days of continued drinking. A forensic autopsy was performed 3days after the discovery of his death in order to specify the cause of death. A longitudinal perforation penetrating all layers of the esophagus measuring 1.8cm was present on the left wall approximately 2.0cm from the gastroesophageal junction. There were 1900mL of greenish to brownish turbid liquid in the left pleural cavity and 150mL of greenish viscous liquid in the stomach...

STUDY OBJECTIVE: Several authors have reported rare, but severe, complications associated with the length of the intravascular guidewire during central venous catheter placement, as the wire tip can cause cardiac arrhythmia or perforation or become trapped within the vessel. Although one report investigated the optimal guidewire length using fluoroscopy, few reports have precisely measured guidewire position using transesophageal echocardiography (TEE). Here, we investigated the appropriate intravascular length of a guidewire for right internal jugular vein approach using TEE during cardiac surgery...

Natural biomaterials, such as chitosan and collagen, are useful for biomedical applications because they are biocompatible, mechanically robust and biodegradable, but it is difficult to rapidly and tightly bond them to living tissues. Here, we demonstrate that the microbial enzyme transglutaminase (mTG) can be used to rapidly (< 5 min) bond chitosan and collagen biomaterials to the surfaces of hepatic, cardiac and dermal tissues, as well as to functionalized polydimethylsiloxane (PDMS) materials that are used in medical products...

Inferior vena cava (IVC) filter is a medical device placed in patients with proven pulmonary embolism or those with risk of embolization. Although many IVC filters are designed for removal after patient recovery, in many instances they are never retrieved. We present a case of a 22-year-old woman who underwent placement of an IVC filter as a prophylactic measure following a C-6 spinal injury that rendered her a quadriplegic. A tyne from the filter later fractured and embolized to the right ventricle, leading to perforation and subsequent large symptomatic pericardial effusion...

BACKGROUND: The endomyocardial biopsy has proven to be an integral diagnostic tool for surveillance of cardiac allograft rejection and identification of myocardial diseases. Nevertheless, this invasive procedure is not risk-free. This study focuses on the risk of complications and diagnostic performance of right ventricular endomyocardial biopsy (EMB). METHODS: In this single-center retrospective study, we analyzed 315 EMB procedures performed between July 2008 and May 2015 in 73 patients...

A 79-years-old woman was diagnosed with severe aortic stenosis and referred to our institution for the purpose of an operation. We decided to perform transfemoral transcatheter aortic valve implantation because of her high frailty due to her age and medication of long-term steroid for chronic rheumatoid arthritis. In the operation, left ventricular perforation occurred by the guide wire and cardiac tamponade was detected. We performed pericardial drainage and controlled bleeding through the 5th intercostal thoracotomy and trasncatheter aortic valve implantation was performed after that...

Cardiac arrhythmia is a major cause of mortality in cardiovascular pathologies. A host of drugs targeted to sarcolemmal Na(+), Ca(2+), and K(+) channels have had limited success clinically. Recently, Ca(2+) signaling has been target of pharmacotherapy based on finding that leaky ryanodine receptors elevate local Ca(2+) concentrations causing membrane depolarizations that trigger arrhythmias. Here we report that xanthohumol, an antioxidant extracted from hops and showing therapeutic effects in other pathologies, may have antiarrhythmic properties by stabilizing ryanodine receptor's activity...

OBJECTIVES: We evaluated the relationship between gender and angiographic and clinical outcomes in patients with severely calcified lesions who underwent orbital atherectomy. BACKGROUND: Female gender is associated with increased risk of adverse clinical events after percutaneous coronary intervention (PCI). Severe coronary artery calcification increases the complexity of PCI and increases the risk of adverse cardiac events. Orbital atherectomy is effective in plaque modification, which facilitates stent delivery and expansion...

BACKGROUND: The most common complication of coronary artery perforation, a rare complication of percutaneous coronary intervention (PCI), is hemopericardium with cardiac tamponade. However, localized extra-coronary bleeding can lead to epicardial hematoma, which is a rare phenomenon. We report the case of an unusual delayed presentation of post-PCI hematoma with unrecognized guidewire perforation. CASE PRESENTATION: A 70-year-old man with idiopathic thrombocytopenic purpura (ITP) and a history of coronary artery bypass grafting (CABG) underwent PCI...

Despite the continuing developments of improved medical devices and increasing operator expertize, coronary chronic total occlusion (CTO) remains as one of the most challenging lesion subsets in interventional cardiology. Percutaneous coronary intervention (PCI) of CTO is a complex procedure carrying the risk of complications that are responsible for significant morbidity and mortality. The complications can be classified as coronary (such as coronary occlusion, perforation, device embolization, or entrapment); cardiac non-coronary (such as periprocedural myocardial infarction); extra cardiac (such as vascular access complications, systemic embolization, contrast-induced nephropathy, and radiation-induced injury)...

Biopharmaceuticals, monoclonal antibody (mAb)-based therapeutics in particular, have positively impacted millions of lives. MAbs and related therapeutics are highly desirable from a biopharmaceutical perspective as they are highly target specific and well tolerated within the human system. Nevertheless, several mAbs have been discontinued or withdrawn based either on their inability to demonstrate efficacy and/or due to adverse effects. Approved monoclonal antibodies and derived therapeutics have been associated with adverse effects such as immunogenicity, cytokine release syndrome, progressive multifocal leukoencephalopathy, intravascular haemolysis, cardiac arrhythmias, abnormal liver function, gastrointestinal perforation, bronchospasm, intraocular inflammation, urticaria, nephritis, neuropathy, birth defects, fever and cough to name a few...

BACKGROUND: Coronary artery perforation associated to cardiac tamponade is an uncommon life-threatening complication of percutaneous coronary intervention, and the occurrence of subepicardial or intramyocardial hematoma without hemopericardium is even rarer. CLINICAL CASE: We describe the case of a 72 year-old woman with a subepicardial hematoma after percutaneous coronary intervention, who required urgent left internal mammary artery graft to anterior descending artery surgery...

We experienced a rare case of post-infarct left ventricular aneurysm (LVA) and ventricular septal perforation (VSP). An 83-year-old woman was treated for acute cardiac insufficiency. Three weeks later after hospitalization, she had sudden cardiorespiratory failure and was diagnosed with VSP and LVA. She underwent emergency heart surgery. After establishing extracorporeal circulation, the LVA was excised longitudinally from the left side of the left anterior descending branch. Endoventricular patch plasty (Dor procedure) was performed to exclude the ventricular aneurysm, and the VSP was closed using Dacron patch...

BACKGROUND AND PURPOSE: Kv 7 (Kv 7.1-7.5) channels play an important role in the regulation of neuronal excitability and the cardiac action potential. Growing evidence suggests Kv 7.4/Kv 7.5 channels play a crucial role in regulating vascular smooth muscle contractility. Most of the reported Kv 7 openers have shown poor selectivity across these five subtypes. In this study, fasudil - a drug used for cerebral vasospasm - has been found to be a selective opener of Kv 7.4/Kv 7.5 channels...
