[Prevalence of coronary anomalies detected by computed tomography at the Instituto Nacional Cardiovascular- INCOR].

Objective: : To determine the prevalence of coronary anomalies (CA) in patients evaluated by 64-detector computed tomography (CT) at the Instituto Nacional Cardiovascular in Peru between 2016 and 2020.

Materials And Methods: Retrospective observational study, coronary artery CT scans of 1486 patients were performed on a 64-detector row CT scanner and reviewed in search for coronary anomalies.

Results: The prevalence of CA detected by CT was 4.

[Prediction of significant coronary lesions by SPECT myocardial perfusion. Results from a national reference hospital in Lima-Peru].

Objective: To determine the discriminative capacity of myocardial perfusion with single photon emission tomography (SPECT) to predict coronary obstructions by coronary angiography. To determine mortality and major cardiovascular events at follow-up.

Materials And Methods: .

A new surgical technique for left atrial reduction in giant left atrium.

Objective: The study objective was to evaluate the safety and clinical and echocardiographic outcomes of a new surgical technique in adult patients diagnosed with a giant left atrium.

Methods: We analyzed a cohort of patients who underwent left atrium reduction surgery between January 2016 and June 2020 performed by a specialized surgical team in 2 national reference centers in Lima, Peru. We assessed the major adverse valvular-related events and the New York Heart Association functional class as primary clinical outcomes.

[Aortic valve reconstruction surgery with Ozaki technique: initials results from a single center].

Background: Aortic valve (AV) replacement is the gold standard treatment for severe symptomatic AV disease. Recently, AV reconstruction surgery (Ozaki procedure) emerges as a surgical alternative with good results in the medium term.

Methods: We retrospectively analyzed 37 patients who underwent AV reconstruction surgery between January 2018 and June 2020 in a national reference center in Lima, Peru.

Attached right aortic valve leaflet causing ischemia and severe regurgitation: Successful repair with Ozaki technique.

Introduction: Coronary artery occlusion due to fusion of a leaflet to the sinotubular junction is a rare finding that we should consider in the differential diagnosis of young patients who have aortic regurgitation and angina.

Patient And Method: We present a young female with severe aortic regurgitation due to right coronary fusion who underwent mini-invasive aortic valve reconstruction.

Results: Postoperative evolution was satisfactory.

Pulmonary Valve Reconstruction Using Autologous Pericardium: A Promising Technique to Consider.

Pulmonary valve (PV) surgical treatment is uncommon in adults; however, when it is indicated, replacement with a prosthesis is suggested. Nevertheless, mechanical prostheses have an inherent risk of complications derived from anticoagulation and thrombosis, and biologic prostheses do not have adequate long-term durability. In this context, PV reconstruction surgery emerges as an alternative, avoiding anticoagulation and promising good durability.

[Coronary artery bypass graft surgery with bilateral internal mammary artery. Short-term results].

Introduction: Coronary artery bypass graft (CABG) surgery remains the reference standard in the treatment of multivessel coronary disease. Several studies have shown that CABG with bilateral internal mammary arteries (BIMA) has better results in long-term survival.

Methodology: A retrospective study was conducted on CABG surgeries with BIMA from January 2012 to December 2015 in the National Cardiovascular Institute, INCOR, EsSalud, Peru.
