RESUMO
Abstract Coronary artery to left atrial fistula is rare in patients with mitral stenosis. We report an interesting case of a patient with concomitant mitral valve stenosis and coronary fistulae, originating from the left circumflex artery and drained into the left atrium with two terminal orifices.

Abstract Objective: To compare the efficacy of blind axillary vein puncture utilizing the new surface landmarks for the subclavian method. Methods: This prospective and randomized study was performed at two cardiology medical centers in East China. Five hundred thirty-eight patients indicated to undergo left-sided pacemaker or implantable cardioverter defibrillator implantation were enrolled, 272 patients under the axillary access and 266 patients under the subclavian approach. A new superficial landmark was used for the axillary venous approach, whereas conventional landmarks were used for the subclavian venous approach. We measured lead placement time and X-ray time from vein puncture until all leads were placed in superior vena cava. Meanwhile, the rate of success of lead placement and the type and incidence of complications were compared between the two groups. Results: There were no significant differences between the two groups in baseline characteristics or number of leads implanted. There were high success rates for both strategies (98.6% [494/501] vs. 98.4% [479/487], P=0.752) and similar complication rates (14% [38/272] vs. 15% [40/266], P=0.702). Six cases in the control group developed subclavian venous crush syndrome and five had pneumothorax, while neither pneumothorax nor subclavian venous crush syndrome was observed in the experimental group. Conclusion: We have developed a new blind approach to cannulate the axillary vein, which is as effective as the subclavian access, safer than that, and also allows to get this vein without the guidance of fluoroscopy, contrast, or echography.

Abstract The universal definition of myocardial infarction (MI) provides five subtypes of acute myocardial infarction (AMI). We present an interesting case of a type 2 myocardial infarction caused by the dilation of the left thoracic stomach.

Abstract Early recognition and rapid and appropriate treatment of cardiac tamponade are mandatory to prevent the irreversible deterioration of cerebral perfusion and other important organs. In this study, cardiac tamponade was induced by inadvertent transseptal puncture, which was managed with pericardial drainage and surgical repair in a patient with symptomatic paroxysmal atrial fibrillation. Epicardial atrial fibrillation ablation and left atrial appendage amputation were also performed at the same time.
