HIV Myocarditis Presenting as Acute ST-Segment Elevation Myocardial Infarction.

Myocarditis is a common occurrence among patients infected with human immunodeficiency virus (HIV). However, it is rare to find HIV-associated myocarditis presenting as ST-segment elevation myocardial infarction with cardiogenic shock. A case of HIV-related myocarditis presenting as an acute inferolateral wall myocardial infarction in a 32-year-old male is described.

Carotid artery stenting prior to coronary artery bypass graft surgery inpatients with left-main-coronary-artery disease.

Patients with concomitant carotid and left main or left main equivalent coronary artery disease are at high risk of both cardiac and cerebrovascular complications when they undergo revascularization procedures. Here, we present case reports of three patients who successfully underwent elective carotid stenting prior to coronary artery bypass surgery. Any sort of intervention in these patients is fraught with high risk due to the severity of their carotid and coronary artery disease.

Long-term results of radiofrequency ablation of slow pathway in patients with atrioventricular nodal reentrant tachycardia: single-center experience.

BACKGROUND: This study sought to evaluate the long-term recurrence rate of atrioventricular nodal reentrant tachycardia (AVNRT) after radiofrequency catheter ablation. The clinical and electrophysiological features of patients with AVNRT and their immediate outcomes after undergoing slow pathway ablation/modification were also studied. METHODS AND RESULTS: The study included 264 consecutive patients with AVNRT (mean age 46 -/+ 15 years, 143 women, 121 men) who underwent slow pathway ablation/modification using a combined electrophysiological and anatomical approach. The primary endpoint of ablation procedure was non- inducibility of the arrhythmia. The primary endpoint of the study was the recurrence of AVNRT on follow-up. Acute success was achieved in 262 (99.6%) patients. Complication rate of the ablation procedure was 2.6% and the average fluoroscopy time was 18.3 -/+ 11 minutes. The patients were followed up for a mean duration of 20 -/+ 9 months during which there was only one case of recurrence. CONCLUSION: Radiofrequency ablation or modification of slow pathway is highly effective in the treatment of AVNRT. The technique has a high initial success rate and a low complication rate. The recurrence rates are extremely low (0.3%) on long-term follow-up.
