ABSTRACT
Objetivos: Evaluar la asociación entre la complejidad de las lesiones y los resultados angiogrßficos, eventos clínicos adversos al mes, a los 6 meses y al a±o. Métodos: Se revisaron retrospectivamente las historias clínicas de 154 pacientes que fueron sometidos a intervencionismo percutßneo coronario en el Instituto Nacional del Corazón- Hospital Guillermo Almenara Irigoyen, entre octubre del 2001 a setiembre del 2002. Se trataron 156 lesiones, de las cuales 91 eran lesiones complejas (definida como la lesión que muestra trombo, calcificación, lesión ostial, bifurcación, aneurisma, oclusión crónica o lesión en puente safeno) y 65 no complejas. Se analizaron variables clínicas, angiogrßficas y resultados de eventos adversos en el seguimiento. Resultados: La edad media de los pacientes fue de 61,7±10,2 a±os, el 83,8 por ciento correspondía al sexo masculino, 63,6 por ciento eran hipertensos y 18,8 por ciento diabéticos. El intervencionismo en lesiones complejas estuvo relacionado con mayor tasa de complicaciones periprocedimiento como fenómeno de no reflujo (71,4 por ciento, p< 0,000), compromiso de brazo colateral (39,6 por ciento, p< 0,000), disección (8,8 por ciento, p< 0,014), embolización distal ( 7,7 por ciento, p<0,02), y eventos adversos al mes de muerte (p< 0,08), muerte/IM (p<0,05), cirugía (p<0,014), muerte/IM/RM( p<0,01), muerte/IM/RM/H (p<0,004), a los 6 meses muerte(p<0,02), muerte/IM (p<0,009), muerte/IM/RM, muerte/IM/RM/H (p< 0,000) y al a±o muerte. Cirugía, muerte/IM, muerte/IM/RM y muerte/IM/RM/H (p<0,01). Conclusiones: Los pacientes con lesiones complejas presentaron una mayor tasa significativa de complicaciones periprocedimiento y eventos adversos (muerte, cirugía, Muerte/infarto, muerte/infarto/revascularización ymuerte/infarto/revascularización/rehospitalización) al mes, a los 6 meses y al a±o.
OBJECTIVES: To evaluate association between coronary lesion complexity and angiographic results, clinical events at first, sixth and twelveth month. METHODS: We retrospectively reviewed clinical charts of 154 patients who underwent coronary percutaneous intervention at the Instituto Nacional del Corazón (INCOR) - National Hospital Guillermo Almenara Irigoyen, between October 2001 and September 2002. 156 lesiones were treated, 91 of them were complex ones (defined as a lesion with thrombus, calcified, ostial lesion, bifurcation, with aneurysm, closed cronically or lesion of a vein graft) and 65 non complex lesions. Clinical, angiographic and clinical events during the foolw up were analyzed. RESULTS: Mean age was 61.7±10.2 years old, 83.8 percent were male, 63.6 per cent had hypertension and 18.8 per cent were diabetic. Intervention in complex lesions was associated with higher rate of periprocedure complications as non reflow phenomenon(71.4 per cent pï0.000), side branch compromise (39.6 per cent pï0.000), dissection (8.8 per cent pï0.014), distal embolisation (7.7 per cent pï0.02) and adverse clinical events at one month of death (pï0.08), death/MI (pï0.05), CABG (pï0.014), death/MI/CABG (pï0.01), death/MI/CABG/hospitalization (pï0.004), at six months death (pï 0.02), death/MI (pï0.009), death/MI/CABG, death/MI,CABG/ hospitalization (pï0.000 ) and death at a year as CABG/death/ MI, death/I/CABG and death/MI,CABG/hospitalization (pï0.01). CONCLUSIONS: Patients with complex lesions showed higher rate of periprocedure complications and adverse cinical events (death, CABG, death/MI, death/MI/CABG and death/MI,CABG/hospitalization) at one, 6 and 12 months.

The cardiomyopathies are defined as a primary disease of the myocardium and occur in children as well as in adults. Restrictive cardiomyopathy is the least common type of cardiomyopathy and is characterized by the restriction of ventricular filling. This condition can affect one or both ventricles. The appropriate diagnostic tool includes a detailed clinical record supported by imaging and hemodynamic studies. The purpose of this study was to evaluate adult patients with suspicion of restrictive miocardiopathy of the right ventricle, from the out-patients clinic using echocardiogram, magnetic resonance imaging, and hemodynamic studies and to establish a differential diagnosis with other cardiovascular diseases. Between May 2003 to January 2006 three patients with different initial diagnoses, such as Ebstein's anomaly, interatrial septal defect, and tumor of the right ventricle were studied. However, once the protocol of the study was completed, the final diagnosis was of right ventricular restrictive cardiomyopathy by endomyocardial fibrosis.
