Background: Takotsubo cardiomyopathy is a non-ischemic cardiomyopathy characterized by acute left ventricular systolic dysfunction with transient wall motion abnormalities without a culprit coronary stenosis or other concurrent diagnoses. Its coexistence with transient high-degree AV block is very infrequent., Case Presentation: A 61-year-old man presented with a new onset of high degree AV block without ST segment deviations developing an anterior and apical dyskinesia with a low left ventricular ejection fraction in the absence of coronary artery disease., Conclusion: Atrioventricular block is an uncommon presentation of Takotsubo syndrome. The management of patients with relevant conduction disorders in this scenario is a challenge for the clinician. In case of persistence of advanced conduction disorders, it seems appropriate to implant a pacemaker.

Organized intracoronary thrombus is associated with adverse outcomes due to distal embolization and no-reflow phenomenon during PCI, particularly in large or ectatic coronary arteries. Intracoronary thrombolysis is an underused but effective and safe strategy. We describe the case of a 56-year-old man admitted due to a subacute myocardial infarction with massive thrombus burden in a right ectatic coronary artery to present the usefulness of a sequential approach with intracoronary thrombolysis, thrombus aspiration and a novel mesh-covered stent implantation as a reasonable and effective strategy to avoid a no-reflow phenomenon during PCI, achieving an immediate successful angiographic result, and a positive long-term clinical outcome.
