ABSTRACT

Background: The incidence rates of cardiac tumors are low. Aim: To report the clinical presentation of cardiac myxomas and long-term evolution after resection. Material and Methods: Review of a database of surgical patients undergoing surgical resection of a cardiac myxoma in a public hospital between 1990 and 2018. Results: Seventy-eight patients aged 53 ± 15 years (65% females) were included. The most frequent comorbidities were arterial hypertension (40.5%), hypothyroidism (15%) and diabetes mellitus (12%). The main presenting symptoms were dyspnea (33%), neurological deficit secondary to embolism (30%) and acute pulmonary edema (5%). The most common location was the left atrium, in 87%. During surgery, cardiopulmonary bypass and aortic cross-clamp times were 50.2 ± 19.6 and 33.4 ± 15.2 min, respectively. One patient died due to severe neurological involvement. Follow-up was completed in seventy-seven patients, with a mean echocardiographic follow-up time of 10.4 ± 7.7 years. Thirty-four patients were followed for more than 10 years. Six patients (7.7%) died during the follow-up and in six patients (7%) a recurrence was identified. Conclusions: Cardiac myxoma usually has nonspecific symptoms. Surgical excision offers excellent short and long-term results. Complications and recurrence rates are low in non-hereditary myxomas but obligates to perform echocardiographic follow-up for early diagnosis of recurrence.

ABSTRACT

We report a 50 year-old hypertensive and asymptomatic woman in whom a left ventricular tumor was found on a routine two-dimensional transthoracic echocardiogram. Complementary 3D echocardiography, cardiac magnetic resonance and cardiac computed tomography allowed the diagnosis of a calcified left ventricular myxoma. Surgical treatment was performed through a transaortic transvalvular approach with tumor resection and implantation of a pericardial bovine patch. This case confirms the importance of transthoracic echocardiography in the diagnosis of cardiac tumors and the complementary role of 3D echocardiography, cardiac magnetic resonance imaging and computed tomography for the differential diagnosis before surgery.

ABSTRACT

Presentamos un caso de infarto agudo al miocardio complicado con shock cardiogénico y arritmias ventriculares refractarias. El paciente requirió oxigenación por membrana extracorpórea (ECMO) antes de su traslado a un hospital con asistencia ventricular izquierda (LVAD) y programa de trasplante de corazón. El paciente tuvo una buena recuperación después de 16 días de soporte con LVAD seguido de trasplante cardiaco, lo que muestra los beneficios de la terapia multimodal en casos complejos de shock cardiogénico refractario.


A case of acute myocardial infarction complicated with cardiogenic shock and refractory ventricular arrhythmias is described. The patient required extracorporeal membrane oxygenation (ECMO) prior to transfer to a hospital with a left ventricular assist device (LVAD) and heart transplantation program. He made a good recovery after 16 days of LVAD support followed by heart transplantation, showing the benefits of multimodal therapy incomplex cases of refractory cardiogenic shock Palabras clave: Infarto agudo del miocardio, shock cardiogénico,asistencia biventricular, ECMO.

ABSTRACT

We report a 16 year old male with a history of angina on exertion. A treadmill exercise test was positive for ischemia in concordance with a Thallium-201 scintigraphy showing a septal and infero-posterior reversible myocardial perfusi¢n defect. Coronary angiography disclosed severe aneurysmal coronary artery disease. Bilateral internal mammary coronary artery bypass grafting was successfully performed. Kawasaki disease is the most likely etiology, although not confirmed.
