Left atrial thrombus (LAT) formation is a feared complication of atrial fibrillation, as it can lead to thromboembolic stroke or thromboembolism to another peripheral region causing ischemia. Despite therapeutic anticoagulation, recurrence of thrombi is still possible, although unlikely. Prevention strategies may include reducing left atrial size along with treatment by surgical removal. We present a case of a patient with a large left atrial thrombus in the setting of previous mitral valve sten...

Hypertrophic cardiomyopathy (HCM) is a disorder characterized by ventricular hypertrophy and myocyte disarray that increases the risk of arrhythmic sudden cardiac death. HCM phenocopies are disease entities sharing a left ventricular hypertrophy phenotype but arising from a different pathologic mechanism. Patients with PRKAG2 syndrome (PS), a glycogen storage disease, are often misdiagnosed as having HCM. Clinicians must be familiar with red flags alerting to the possibility of this important di...

Paravalvular leak (PVL) driven intravascular hemolysis (IVH) is a recognized complication of surgical aortic valve replacement. This has been described less following transcatheter aortic valve implantation (TAV). We present a case of a patient with severe life-threatening hemolytic anemia following TAV, requiring multiple blood transfusions, and emergent TAV-in-TAV procedure....

COVID-19 infection has shown cardiovascular involvement, particularly when it has a moderate to severe presentation. This alteration has been manifested in arrhythmias, myocarditis, and acute myocardial infarction, among others; persistence of these cardiovascular alterations in the short and medium term has been documented. In Latin America there are no reports of long-term cardiovascular sequelae. We present the case of a 46-year-old female with no previous history of cardiovascular disease wh...
