RESUMEN
Cardiac tumors, due to the various clinical scenarios and their histological subtypes, are still challenging for clinicians. They are differentiated into primary and secondary. The latest are more common and are usually lung and breast cancers, melanomas, and lymphoma metastasis. We present a case of a 73-year-old woman, with a history of breast cancer 10 years earlier, admitted to Cath lab for an elevation of the ST-segment of the electrocardiogram, myocardial infarction. Echocardiogram showed a curious abnormality in the myocardial wall. Thanks to a multimodality imaging strategy, including contrast-enhanced echocardiography and cardiac magnetic resonance, characterization of the underlying pathology was clear and, thus, the appropriate management and therapy.
This is the case of a cardiac metastatic tumor, whose certain diagnosis can only be made by myocardial biopsy an invasive sample of heart tissue unfortunately not available in our case. Alternatively, we puzzled data from two second-level imaging techniques: contrast-enhanced cardiac ultrasound and cardiac magnetic resonance, which allowed us to better evaluate the nature of this cardiac mass. The former gave information about its blood supply, the latter gave information about tissue characterization. In this paper, we show how a complete integration of data from clinical and a stepwise multimodality imaging-based approach may allow a diagnosis in a complex clinical case.

There is an increasing awareness on the association between mitral valve prolapse (MVP) and sudden cardiac death. Mitral annular disjunction (MAD) is a phenotypic risk feature that can help in risk stratification. We present a case of a 58-year-old woman who experienced an out-of-hospital cardiac arrest caused by ventricular fibrillation interrupted by a direct current shock. No coronary lesions were documented. Echocardiogram showed myxomatous MVP. Nonsustained ventricular tachycardia have been registered during hospital stay. Interestingly, cardiac magnetic resonance revealed MAD and a late gadolinium enhancement area in inferior wall. Finally, a defibrillator has been implanted. For arrhythmic risk stratification of MVP with MAD, multimodality imaging is the diagnostic tool to find out the disease behind many cardiac arrests of unknown cause.

Pseudoaneurysm of the mitral-aortic intervalvular fibrosa (MAIVF-P) is one of the rare complications of endocarditis or, more rarely, of surgical trauma. This condition is characterized by a pseudoaneurysm in the intra-annular area between the mitral valve and the aortic valve communicating with the outflow tract of the left ventricle, between the coronary or noncoronary left aortic valve and the front flap of the mitral valve. Nowadays, surgery is recommended to avoid further growth and complications. We hereby describe the case of a patient with MAIVF-P as a consequence of a surgical trauma and early appearance of MAIVF-P. During the long echocardiographic and clinical follow-up, the patients showed stable clinical and hemodynamic conditions despite the increase in size of the MAIVF-P. A conservative treatment based on a medical follow-up can represent an alternative in patients refusing surgery, in high-risk surgical patients as well as in patients showing a stable echocardiographic and clinical picture regardless of the MAIVF-P size.
