Hamid Attaran
Methamphetamine is one of the most common abused drugs, so its various effects on different body organs should be familiar to all physicians. Regarding its gastrointestinal sequels, there are few reports of ischemic colitis induced by its vasoconstrictive effects. This is the first report of isolated small intestinal infarction resulting in death following methamphetamine toxicity. A 40-year-old woman with a past history of medical treatment for obesity referred to hospital with severe chest and back pain, perspiration, nausea, agitation, high blood pressure, bradycardia and subsequent lethargy and vasomotor instability...

OBJECTIVES: We evaluated the angiographic and clinical outcomes in patients with severely calcified lesions and systolic dysfunction who underwent orbital atherectomy (OA). We hypothesized that OA would provide similar outcomes in patients with systolic dysfunction compared with patients with preserved systolic function. BACKGROUND: Systolic dysfunction is associated with an increased risk of adverse clinical events after percutaneous coronary intervention (PCI)...

PURPOSE: A previously published cardiac-gated 2D Qflow protocol at 7 T in cerebral perforating arteries was optimized to reduce velocity underestimation and improve temporal resolution. METHODS: First, the signal-to-noise ratio (SNR) gain of the velocity measurement (SNRv ) was tested for two signal averages versus one. Second, the decrease in velocity underestimation with a tilted optimized nonsaturating excitation (TONE) pulse was tested. Third, the decrease in pulsatility index (PI) underestimation through improved temporal resolution was tested...

A 56-year-old woman presented with acute onset of typical chest pain. She was diagnosed with acute coronary syndrome with ST-segment elevation myocardial infarction. Although significant obstructive coronary artery disease was ruled out by coronary angiography, cardiac MRI showed transmural necrosis of the lateral free wall with extensive microvascular obstruction consistent with ischaemic heart disease. Within 48 hours after initial presentation, the patient suddenly arrested due to pulseless electrical activity with futile resuscitation efforts...

Several remote catheter navigation systems have been developed and are now commercially available. However, these systems typically require specialized catheters or equipment, as well as time-consuming operations for the system set-up. In this paper, we present CathROB, a highly compact and versatile robotic system for remote navigation of standard tip-steerable electrophysiology (EP) catheters. Key features of CathROB include an extremely compact design that minimizes encumbrance and time for system set-up in a standard cath lab, a force-sensing mechanism, an intuitive command interface, and functions for automatic catheter navigation and repositioning...

BACKGROUND: Cardiac tamponade due to aortic injury after blunt trauma is a rare and potentially fatal injury. Most aortic injuries caused by blunt trauma present as aortic dissection or rupture of the aortic isthmus. Several cases of delayed aortic injury have been reported. However, all of these injuries were observed in the descending aorta because they had been caused by a posterior rib fracture. CASE PRESENTATION: We report the first case of cardiac tamponade associated with delayed ascending aortic perforation 2 weeks after blunt trauma...

Myocardial perforation by pacemaker electrode is a very serious complication. Usually, the pacemaker electrode perforates the right ventricle, but rarely the left ventricular myocardium. We describe an 82-year-old female patient who presented with left ventricular pacing after temporary pacemaker implantation and was diagnosed with myocardial perforation. Emergency thoracotomy showed that the exact position of the cardiac perforation was close to the left ventricular apex. Perforation of the left ventricular free wall by an electrode sometimes progresses slowly...

Ventricular septal perforation(VSP) after blunt chest trauma is rare. As the clinical symptoms and timing of presentation are varied, appropriate diagnosis can be difficult or delayed. An 86-year-old man presented with a traumatic VSP following a forestry injury. He showed a normal cardiac structure at the time of injury, but echocardiography after 9 days revealed VSP. He was treated successfully with surgical closure of the VSP.

Worldwide primary angioplasty is a recommended strategy of reperfusion in patient with acute myocardial infarction as because it ensures reperfusion of the infarct-related vessels more than 90% whereas, with thrombolytics it is only 60-70%. This retrospective observational study includes all patients treated with primary angioplasty at United Hospital from Between March 2007 to January 2011. Total 114 consecutive patients with acute myocardial infarction were treated with primary angioplasty included. Those presented beyond 12 hours of onset of chest pain, in cardiogenic shock, resuscitate and intubated before the procedure were excluded from the study...

OBJECTIVE: Mitral valve (MV) regurgitation due to degenerative MV disease is the leading cause of cardiac death in dogs. We carried out preliminary experiments to determine the feasibility and short-term effects of beating-heart MV repair using an expanded polytetrafluorethylene (ePTFE) chordal implantation device (Harpoon TSD-5) in dogs. ANIMALS: This study involved six healthy purpose-bred Beagles (weight range 8.9-11.4 kg). MATERIAL AND METHODS: Following a mini-thoracotomy performed under general anesthesia, the TSD-5 was used to place 1 or 2 artificial ePTFE cords on the anterior MV leaflet or the posterior MV leaflet via a left-ventricular transapical approach...

This case describes a complication of bone cement use. A 65-year-old male patient with back spine trauma caused by a fall, underwent a percutaneous vertebroplasty. Five years later, he consulted for palpitations, and the electrocardiogram showed supraventricular arrhythmia. A transthoracic two-dimensional echocardiography showed a hyperechogenic linear structure of 7 cm length, running from the lateral wall of the right ventricle to the right atrium through the tricuspid valve. This foreign body, which was suspicious for bone cement embolism, appeared rigid and was attached at the lateral wall of the right ventricle, with its proximal end free in the right atrium...

BACKGROUND: Purkinje cells (PCs) are important in cardiac arrhythmogenesis. Whether small-conductance calcium-activated potassium (SK) channels are present in PCs remains unclear. We tested the hypotheses that subtype 2 SK (SK2) channel proteins and apamin-sensitive SK currents are abundantly present in PCs. METHODS AND RESULTS: We studied 25 normal rabbit ventricles, including 13 patch-clamp studies, 4 for Western blotting, and 8 for immunohistochemical staining...

Endocardial mapping of the left ventricle (LV) using the NOGA® XP Cardiac Navigation System can identify chronically ischemic and viable myocardium in patients with coronary artery disease by generating electromechanical maps. These maps are very useful when targeting myocardial tissue for injection of stem cells. We present the case of a woman who developed a perforation at the site of an LV aneurysm during NOGA mapping prior to the transendocardial injection of stem cells, as part of a multicenter clinical trial...

BACKGROUND: Superior vena cava (SVC) lacerations have been identified as the most lethal complication encountered during cardiac implantable electronic device lead extraction. The case fatality rate of these events approximates 50% due to rapid exsanguination. A novel, compliant balloon specifically designed for use in the SVC may provide hemostasis in the event of endovascular perforation. By temporarily occluding the compromised vessel, the endovascular balloon should delay hemodynamic collapse, provide a more controlled surgical field for repair, and thereby reduce the mortality of SVC tears complicating transvenous lead extraction...

BACKGROUND: First-in-man studies of leadless pacemakers have demonstrated high rates of implant success, and safety and efficacy objectives were achieved. Outside of the investigational setting, there are concerns, particularly over cardiac effusion and perforation, device dislodgement, infection, telemetry, and battery issues. OBJECTIVE: The acute performance of the Micra transcatheter pacemaker from a worldwide postapproval registry is reported. METHODS: The registry is an ongoing prospective single-arm observational study designed to assess the safety and effectiveness of Micra in the postapproval setting...

Acupuncture is an alternative medical therapy and widely practiced in Northeast Asia. Although it is known as a safe procedure, complications including infection, pneumothorax, hemorrhage, and cardiac tamponade have been reported. The authors present a rare case of fatal acute peritonitis due to penetration of acupuncture needles directly into the abdominal and pelvic cavity. The victim was a 55-year-old woman who had a recent history of chemo-radiotherapy due to breast cancer. She was collapsed three days after receiving acupuncture...

BACKGROUND: To minimize cardiac perforation during the minimally invasive repair of pectus excavatum (MIRPE), several surgeons have suggested using a suction device to intraoperatively lift the sternum. Whether or not this technique is effective for all PE patients is not yet known. As such, our aim was to quantify the extent to which a suction device is capable of lifting the sternum with a short duration of use. METHODS: 30 PE patients received a low-dose CT scan as part of standard PE evaluation...

Irreversible electroporation (IRE) is a nonthermal ablation modality employed to induce in situ tissue-cell death. This study sought to evaluate the efficacy of a novel high-frequency IRE (H-FIRE) system to perform hepatic ablations across, or adjacent to, critical vascular and biliary structures. Using ultrasound guidance H-FIRE electrodes were placed across, or adjacent to, portal pedicels, hepatic veins, or the gall bladder in a porcine model. H-FIRE pulses were delivered (2250 V, 2-5-2 pulse configuration) in the absence of cardiac synchronization or intraoperative paralytics...
