Article Synopsis
- The study aimed to evaluate the types of cardiac surgeries conducted at the National Cardiovascular Institute in Peru, focusing on operative mortality and complications within 30 days post-surgery.
- In 2022, there were 503 surgeries, with most patients being male; the most common procedures were isolated valvular surgeries (27%) and myocardial revascularization (21.9%), with an overall mortality rate of 4.5%.
- The study concluded that valvular surgeries were the most common, and the mortality rates, particularly for elective (2.8%) and emergency (14.3%) surgeries, were considered acceptable for the center's standards.
Article Synopsis
- A 19-year-old woman with a past aortic valve balloon procedure was admitted due to severe aortic valve stenosis and a narrow annulus.
- The surgical team initially planned to reconstruct the aortic valve using her own pericardium.
- During surgery, they discovered a unicuspid valve and proceeded to enlarge the aortic valve annulus.
We present the case of a 56-year-old male patient with a history of atrial flutter for six months; he was admitted to the hospital for presenting a mass of 8 cm in maximum diameter in the right atrium, which prolapsed through the tricuspid valve into the right ventricle. Emergency surgery was scheduled, performing exeresis of the tumor and tricuspid annuloplasty. The Pathological anatomy determined that the removed mass corresponded to a cardiac lipoma.

Objectives: To assess mortality, major valve-related events (MAVRE), and other complications in the perioperative period and follow up in patients with aortic valve replacement (AVR) through mini-thoracotomy (MT).
Methods: We retrospectively analyzed patients aged <80 who underwent AVR through MT between January 2017 and December 2021 in a national reference center in Lima, Peru. Patients undergoing other surgical approaches (mini-sternotomy, etc.
We present a 64-year-old woman who underwent mitral, aortic, and tricuspid valve (TV) replacement with mechanical prostheses. Two months after TV surgery, she presented third-degree atrioventricular block. After attempting to place a pacemaker lead through the coronary sinus, it was placed through the mechanical valve in the tricuspid position as the last option.

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.
Article Synopsis
- Aortic valve reconstruction surgery (Ozaki procedure) is a promising alternative to traditional aortic valve replacement, showing good medium-term results in a study of 37 patients.
- Most patients had AV stenosis, primarily due to a bicuspid valve, and additional surgery was often required for related conditions.
- The procedure had a low in-hospital death rate, with significant improvements in aortic valve function and high survival rates during follow-up, indicating its effectiveness and safety.
Article Synopsis
- Coronary artery occlusion from leaflet fusion at the sinotubular junction is uncommon but should be considered in young patients with aortic regurgitation and angina.
- A young female patient with severe aortic regurgitation caused by right coronary fusion successfully underwent mini-invasive aortic valve reconstruction.
- The Ozaki technique is effective for treating aortic regurgitation resulting from single leaflet dysfunction, as demonstrated by the patient's positive postoperative outcome after 3.5 years.
Article Synopsis
- Pulmonary valve surgery in adults is rare but suggested when needed, typically involving prosthetic replacement.
- Mechanical prostheses pose risks related to blood clots and need for blood thinners, while biologic ones lack long-term durability.
- PV reconstruction surgery offers a promising alternative, avoiding anticoagulation and showing good durability, as demonstrated in four patients with severe valve issues.
Article Synopsis
- CABG surgery using bilateral internal mammary arteries (BIMA) shows improved long-term survival rates in patients with multivessel coronary disease.
- A study conducted at INCOR, Peru, from 2012 to 2015 found that among 36 CABG patients, the 30-day mortality rate was 0% and major cardiovascular events occurred in only 5.56%.
- The results suggest that CABG with BIMA is a safe option with low risk of mortality and complications shortly after surgery, making it a viable choice for patients.
