Ventricular Tachycardia in an Elderly Male With Brugada Syndrome.

We present a case of Brugada syndrome in a 74-year-old patient who presented with urine retention and incidentally found to have non-sustained ventricular tachycardia (NSVT) on electrocardiogram (ECG) and telemetry. To reveal characteristic type 1 Brugada pattern, right-pericardial lead was placed in the third right intercostal space. No antiarrhythmics were started, a loop recorder was implanted, and on follow-up episodes of self-terminating sustained ventricular tachycardia (VT) were noted.

Elusive for Years: Rare Biatrial Myxoma.

• Biatrial cardiac myxoma is an extremely rare pathology. • Cardiac masses present as valve obstruction, embolism, and constitutional symptoms. • TTE is important in patients with exertional dyspnea to rule out cardiac causes.

Swallowing-induced atrial tachycardia: A rare demonstration on fluoroscopic esophagram.

Background: Swallowing-associated arrhythmias are rare and most commonly present as atrial tachycardias.

Methods: We present a case of a 45-year-old female who experienced frequent episodes of palpitations and dyspnea occurring immediately after swallowing solid food. She was noted to have atrial tachycardia with deglutition that was recorded on the 12-lead electrocardiogram.

Benign Metastasizing Leiomyoma Causing Severe Tricuspid Regurgitation and Heart Failure.

We present the case of a 51-year-old woman with severe tricuspid valve regurgitation due to aseptic tricuspid valve vegetation. She presented with bilateral lower extremity edema and a tricuspid valve vegetation was found on echocardiography. Initially, infectious and autoimmune causes of valve vegetation were considered; however, on biopsy, the mass was ultimately found to be a benign metastasizing leiomyoma (BML).

Beta-blockers for chest pain associated with recent cocaine use.

Background: Although beta-blockers prevent adverse events after myocardial infarction, they are contraindicated when chest pain is associated with recent cocaine use. Recommendations against this use of beta-blockers are based on animal studies, small human experiments, and anecdote. We sought to test the hypothesis that beta-blockers are safe in this setting.

Intradiscal thermal therapy using interstitial ultrasound: an in vivo investigation in ovine cervical spine.

Study Design: In vivo investigation of intradiscal ultrasound thermal therapy in ovine cervical spine model.

Objective: To evaluate the potential of interstitial ultrasound for selective heating of intradiscal tissue in vivo.

Summary Of Background Data: Application of heat in the spine using resistive wire and radiofrequency current heating devices is currently being used clinically for minimally invasive treatment of discogenic low back pain.

Intradiscal thermal therapy does not stimulate biologic remodeling in an in vivo sheep model.

Study Design: Thermal energy was delivered in vivo to ovine cervical discs and the postheating response was monitored over time.

Objectives: To determine the effects of two distinctly different thermal exposures on biologic remodeling: a "high-dose" regimen intended to produce both cellular necrosis and collagen denaturation and a "low-dose" regimen intended only to kill cells.

Summary Of Background Data: Thermal therapy is a minimally invasive technique that may ameliorate discogenic back pain.

Feasibility of using interstitial ultrasound for intradiscal thermal therapy: a study in human cadaver lumbar discs.

Application of heat in the spine using resistive wire heating devices is currently being used clinically for minimally invasive treatment of discogenic low back pain. In this study, interstitial ultrasound was evaluated for the potential to heat intradiscal tissue more precisely by directing energy towards the posterior annular wall while avoiding vertebral bodies. Two single-element directional applicator design configurations were tested: a 1.
