Multimodality detection of multiple left ventricular diverticula: A case report and brief review of the literature.

Left ventricular diverticula (LVD) are rare congenital anomalies usually detected incidentally in the adult population. Most commonly, they are found as a single left ventricular diverticulum in association with other congenital abnormalities but multiple LVD are exceedingly rare. We are describing a patient who was found to have multiple LVD on multimodality imaging studies. He had presented with a sudden cardiac arrest attributed to a combination of alcohol intoxication and QT interval prolongation from hypokalemia and antidepressant medications. The patient was managed conservatively and discharged with an implantable loop recorder for detecting any occult arrhythmias.

Diagnosis and treatment of spontaneous coronary artery pseudoaneurysm: Rare anomaly with potentially significant clinical implications.

Spontaneous coronary artery pseudoaneurysm (PSA, false aneurysm) is an extremely rare occurrence with the precise incidence unknown. It is defined as an outwardly bulging monolayer or double layer within the coronary artery that lacks all 3 layers (intima, media, and adventitia) of the arterial wall. Coronary PSA commonly occurs from arterial dissection or perforation induced by catheter intervention, infection, pregnancy, or trauma. Traumatic dissection or perforation of the coronary artery after a percutaneous coronary intervention (PCI) remains the most common cause. Such cases may progress to myocardial ischemia, acute myocardial infarction, or acute coronary artery rupture causing death from cardiac tamponade. Intravascular ultrasound or cardiac computed tomography may aid in the diagnosis. Treatment options include PCI with a covered stent, bare or drug-eluting stent, coil embolization, coronary artery bypass graft with isolation of the PSA, or conservative management with vigilant clinical follow-up. In this review, we sought to describe the diagnosis, etiology, treatment, and the limited literature on spontaneous coronary artery PSA. © 2017 Wiley Periodicals, Inc.

Septic thrombophlebitis: percutaneous mechanical thrombectomy and thrombolytic therapies.

Suppurative thrombophlebitis (Lemierre's syndrome) of the internal jugular vein is a rare and sometimes fatal complication. It commonly occurs from oropharyngeal infections, peripheral lines, complications from dental procedures, gingivitis, or central venous catheterizations. Empiric antibiotics are the initial treatment of choice followed by thrombolytics or surgical thrombectomy in refractory cases. We present a case of septic thrombophlebitis of the right internal jugular vein from a peripherally inserted central venous catheter. We also review the current percutaneous mechanical thrombectomy and thrombolytics therapies for such a rare disorder. Mechanical thrombectomy includes rotational thrombectomy or rheolytic therapies. Devices include the Amplatz thrombectomy device (Microvena), the Arrow-Trerotola Percutaneous thrombolytic device (Arrow), and the Cragg-Casteneda thrombolytic brush (Microtherapeutics). Rheolytic therapies include Angiojet, the Hydrolyzer, and the Oasis Thrombectomy System. Percutaneous mechanical thrombectomy techniques include rotational fragmentation, aspiration or suction thrombectomy, and hydrodynamic thrombectomy. AngioJet catheters may be used for percutaneous embolectomy in conjunction with pulse spray techniques, which instill thrombolytics locally. Thrombolytics include streptokinase, urokinase, and recombinant-tissue plasminogen activator. Mechanical thrombectomy combined with thrombolytics provide optimal treatment results secondary to their complementary effects. Therefore, patients who are refractory to standard medical therapy and considered poor surgical candidates may benefit from combined percutaneous mechanical thrombectomy with thrombolytics to achieve superior results if no contraindications exist for thrombolytics.

Early versus delayed percutaneous coronary intervention for patients with non-ST segment elevation acute coronary syndrome: a meta-analysis of randomized controlled clinical trials.

BACKGROUND: Studies assessing the timing of percutaneous coronary interventions (PCI) in patients with Non-ST segment elevation Acute Coronary Syndromes (NSTE-ACS) have failed to generate a consensus on how early PCI should be performed in such patients. PURPOSE: This meta-analysis compares clinical outcomes at 30 days in NSTE-ACS patients undergoing PCI within 24 hours of presentation (early PCI) with those receiving PCI more than 24 hours after presentation (delayed PCI). DATA SOURCES: Data were extracted from searches of MEDLINE (1990-2010) and Google scholar and from scrutiny of abstract booklets from major cardiology meetings (1990-2010). STUDY SELECTION: Randomized clinical trials (RCTs) that included the composite endpoint of death and non-fatal myocardial infarction (MI) at 30 days after PCI were considered. DATA EXTRACTION: Two independent reviewers extracted data using standard forms. The effects of early and delayed PCI were analyzed by calculating pooled estimates for death, non-fatal MI, bleeding, repeat revascularization and the composite endpoint of death or non-fatal MI at 30 days. Univariate analysis of each of these variables was used to create odds ratios. DATA SYNTHESIS: Seven studies with a total of 13,762 patients met the inclusion criteria. There was no significant difference in the odds of the composite endpoint of death or non-fatal MI at 30 days between patients undergoing early PCI and those receiving delayed PCI (OR-0.83, 95%CI 0.62-1.10). Patients receiving delayed PCI experienced a 33% reduction in the odds of repeat revascularization at 30 days compared to those undergoing early PCI (OR-1.33, 95%CI 1.14-1.56, P=0.0004).Conversely, patients undergoing early PCI experienced lower odds of bleeding than those receiving delayed PCI (OR-0.76, 95%CI 0.63-0.91, P = 0.0003). CONCLUSIONS: In NSTE-ACS patients early PCI doesn't reduce the odds of the composite endpoint of death or non-fatal MI at 30 day. This strategy is associated with lower odds of bleeding and higher odds of repeat revascularization at 30 days than a strategy of delayed PCI.

Fish oil supplementation & coronary artery disease: does it help?

Omega-3 polyunsaturated fatty acids (PUFAs) have been shown to decrease the risk of cardiovascular disease. They reduce fatal and non-fatal myocardial infarction, stroke, coronary artery disease (CAD), sudden cardiac death, and all-cause mortality. They are well tolerated and cause minimal adverse effects. In this review, we sought to provide an overview of the current literature on the use of Omega-3 fatty acids for the treatment of CAD and discuss the possible benefits.

Successful Percutaneous Retrieval of Embolized Septal Occluder Device from Aortic Arch and Placement of a Newer Septal Occluder Device in Combined Procedure.

Embolization of the Amplatzer Septal Occluder (ASO) device (St. Jude Medical, Minnesota) after percutaneous closure of atrial septal defect (ASD) is a rare and potentially catastrophic complication. Percutaneous retrieval of the embolized device is gaining ground as an acceptable method, although these patients are usually subsequently referred for open surgical closure of the ASD. We present a unique case of percutaneous retrieval embolized ASO device and placement of newer larger ASO device in a single procedure.
