Management of Hypertrophic Obstructive Cardiomyopathy with a Focus on Alcohol Septal Ablation
TCTAP C-017 Successful Treatment of Prolonged Out-of-hospital Cardiac Arrest with Automatic Mechanical Chest Compression Device and Intra-arrest Primary Percutaneous Coronary Intervention
Computed tomography angiography-guided recanalization of saphenous vein graft chronic total occlusion
Computed tomography (CT) angiography can augment conventional coronary angiography relative to length of vessel occlusion and quality of distal run-off. In this case report we describe the significance of CT angiography in the revascularization decision-making process of a patient following occlusion of both coronary artery bypass grafts
Uncommon cause of obstruction in the left ventricular outflow tract by a metastasis of adenocarcinoma
Cardiac metastases are rare diagnoses among cardiac disorders. This case demonstrates a unique presence of an obstruction in the left ventricular outflow tract caused by the metastasis of a renal carcinoma. Adequate diagnostic and therapeutic procedures were lifesaving in this potentially fatal diagnosis
Predictors of coronary intervention-related myocardial infarction in stable angina patients pre-treated with statins
Effect of Catheter-Based Patent Foramen Ovale Closure on the Occurrence of Arterial Bubbles in Scuba Divers
ObjectivesThis study sought to evaluate the effect of catheter-based patent foramen ovale (PFO) closure on the occurrence of arterial bubbles after simulated dives.BackgroundPFO is a risk factor of decompression sickness in divers due to paradoxical embolization of bubbles. To date, the effectiveness of catheter-based PFO closure in the reduction of arterial bubbles has not been demonstrated.MethodsA total of 47 divers (age 35.4 ± 8.6 years, 81% men) with a PFO (PFO group) or treated with a catheter-based PFO closure (closure group) were enrolled in this case-controlled observational trial. All divers were examined after a simulated dive in a hyperbaric chamber: 34 divers (19 in the PFO group, 15 in the closure group) performed a dive to 18 m for 80 min, and 13 divers (8 in the PFO group, 5 in the closure group) performed a dive to 50 m for 20 min. Within 60 min after surfacing, the presence of venous and arterial bubbles was assessed by transthoracic echocardiography and transcranial color-coded sonography, respectively.ResultsAfter the 18-m dive, venous bubbles were detected in 74% of divers in the PFO group versus 80% in the closure group (p = 1.0), and arterial bubbles were detected in 32% versus 0%, respectively (p = 0.02). After the 50-m dive, venous bubbles were detected in 88% versus 100%, respectively (p = 1.0), and arterial bubbles were detected in 88% versus 0%, respectively (p < 0.01).ConclusionsNo difference was observed in the occurrence of venous bubbles between the PFO and closure groups, but the catheter-based PFO closure led to complete elimination of arterial bubbles after simulated dives.
