Clinical and hemodynamic outcomes and mortality risk factors in patients undergoing pulmonary thromboendarterectomy.

Background: Pulmonary thromboendarterectomy is the current treatment of choice in patients with chronic thromboembolic pulmonary hypertension. The objective of the present study was to analyze the clinical and hemodynamic outcomes and the risk factors for mortality in a cardiovascular center in Colombia.

Methods: Cohort study, conducted between 2001 and 2019.

Arterial lactate levels and their prognostic value in patients undergoing pulmonary thromboendarterectomy.

Objective: Evaluate the change of lactate levels and its prognostic role in the postoperative period of patients undergoing pulmonary thromboendarterectomy.

Methods: Retrospective study between 2001 and 2019. Patients older than 18 years and who underwent pulmonary thromboendarterectomy were included.

[Intra-aortic balloon counterpulsation placed through the subclavian artery as a bridge to heart transplantation. Case report].

Advanced heart failure is a major health problem for which heart transplantation or left ventricular assist devices are the only effective treatments. Intra-aortic balloon pump inserted using femoral artery access as a bridge to heart transplantation is still frequently used, but has the disadvantage of limiting the patient's movements, hence exposing him or her to the hazards of immobility and threatening the success of the procedure or hindering recovery. Access through the subclavian artery has become an attractive alternative since it doesn't impair the patient's mobility, and there is increasing evidence supporting its use.

[Coronary chronic total occlusion and bifurcation lesions, lessons from contemporary management: case report].

Coronary artery disease involving chronic occlusions and bifurcation lesions continues to be a challenge for the interventional cardiologist. The improvement in the techniques has allowed a higher success rate, however, the best intervention strategy is unknown in this subgroup of patients with chronic occlusions and associated bifurcation lesions. We present the case of a patient in whom, in an angiography for study of chest pain, a chronic total occlusion and a bifurcation lesion were evidenced and were successfully treated by coronary intervention.

[Heart Failure With Preserved Ejection Fraction: A Problem Of Contemporary Cardiology].

Heart failure with preserved ejection fraction (HFpEF) is a frequent and overlooked medical condition that represents a great challenge for diagnosis and treatment. Current data shows a temporal trend towards a higher prevalence of HFpEF, even above heart failure with reduced ejection fraction (HFrEF). The pathophysiology of HFpEF is heterogeneous and involves several factors such as genetics, lifestyle, and cardiac and non-cardiac comorbidities.
