Lesión cutánea por radiación en angioplastía coronaria compleja / Cutaneous radiation injury after failed percutaneous coronary angioplasty

Resumen: Las lesiones cutáneas por radiación (LCR) son una complicación infrecuente, con un estimado de 3.600 casos de lesiones mayores reportados en la actualidad. Presentamos un caso de lesión eritematosa mayor por radiación posterior a angioplastía coronaria fallida y en segundo tiempo angioplastía coronaria con rotablación.

Abstract: Cutaneous radiation injuries are an infrequent complication, with an estimated 3.600 cases of major injuries reported up to now. We present a case of a major erythematous lesion induced by radiation after failed coronary angioplasty and consecutive coronary rotablation.

Perforación miocárdica subaguda relacionada a electrodo de marcapasos. Reporte de caso y revisión de la literatura / Subacute myocardial perforation related to a pacemaker lead. Case report and literature review

Resumen La perforación miocárdica relacionada a electrodos de estimulación cardiaca es una complicación poco frecuente, pero desafortunada, ya que sus implicaciones clínicas son potencialmente letales. Nosotros describimos la evolución fluoroscópica de un caso de perforación subaguda del ventrículo derecho, así como el análisis en función de la revisión de la literatura. © 2017 Instituto Nacional de Cardiología Ignacio Chávez.

Detección y tratamiento de la placa vulnerable / Detection and treatment of vulnerable plaque

Advances in the understanding of the role of vulnerable plaque coupled with novel diagnostic and therapeutic approaches create a unique opportunity for cardiovascular events prevention due to rupture of vulnerable plaques. Currently, non-invasive methods do not have enough resolution to identify vulnerable plaques, on the other hand, some invasive methods can define the morphological and anatomic characteristics of vulnerable plaques. These invasive methods include intravascular ultrasound and three dimensional intravascular ultrasound, virtual histology, optical coherence tomography, intravascular magnetic resonance and intracoronary angioscopy. Atherosclerotic plaques causing symptoms require local treatment but the systemic nature of the atherosclerotic process requires global therapeutic approach for the prevention of cardiovascular events.

Choque cardiogénico: El tratamiento en el futuro cercano / Cardiogenic shock: treatment of the near future

The mortality rate for cardiogenic shock has decreased over the past decade. These improvements are presumed to reflect increased use of intraaortic ballon counterpulsation and coronary reperfusion strategies which, by restoring patency to the infarct-related artery, can limit infarct size. Despite these therapeutic measures, mortality rates remain elevated. Current strategies are aimed at decreasing reperfusion times and measures to preserve and prolong myocardial cell viability.
