[Analysis of cardiac surgeries and operative mortality at the National Cardiovascular Institute during 2022]. / Análisis de las cirugías cardíacas y mortalidad operatoria en el Instituto Nacional Cardiovascular durante el 2022.

Objective: To describe cardiac surgeries, their approaches, and determine operative mortality according to the type of surgery and the main complications recorded within 30 days postoperatively, performed at the National Cardiovascular Institute of Peru. Materials and methods: A descriptive study was conducted on all patients over 18 years of age who underwent cardiovascular surgery at the National Cardiovascular Institute "Carlos Alberto Peschiera Carrillo". Results: During the year 2022, a total of 503 cardiac surgeries were performed. Of the patients undergoing surgery, 63.6% (320) were males. Isolated valvular surgery, primarily aortic or mitral valve replacement, was the most frequent surgical procedure, with 136 surgeries (27.0%). This was followed by myocardial revascularization surgery with 110 procedures (21.9%). Throughout the year, there were 23 deaths, resulting in an overall mortality rate of 4.5%. The mortality rate for elective surgeries was 2.8%, while for emergency surgeries, it was 14.3%. The most common complication was paroxysmal atrial fibrillation (14.0%), followed by surgical site infection with 52 cases (10.3%). Conclusions: Valvular surgery, whether isolated or combined with other procedures, was the most frequently performed. The obtained mortality rate is considered acceptable for a reference center.

Aortic valve reconstruction surgery with Ozaki technique: initials results from a single center / Cirugía de reconstrucción de válvula aórtica con técnica de Ozaki: resultados iniciales en un centro de referencia

Abstract 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. The median age was 62 years, interquartile range (IQR: 42-68). The main indication for surgery was AV stenosis (62.2%), in most cases due to bicuspid valve (19 patients, 51.4%). Twenty-two (59.4%) patients had another pathology with surgical indication associated to AV disease, 8 (21.6%) had dilatation of the ascending aorta with indication for replacement. Results: One in-hospital death occurred (1/38, 2.7%) due to perioperative myocardial infarction. There was a significant reduction in the medians of the peak (70 mmHg, CI 95% = 50.03-79.86 vs. 14 mmHg, CI 95% = 11.93-17.5, p < 0.0001) and mean (45.5 mmHg CI 95% = 30.6-49.68 vs. 7 mmHg, CI 95% = 5.93-9.6, p < 0.0001) AV gradients when we compared baseline characteristics with first 30-days results. In an average of 19 (± 8.9) months of follow-up, survival, reoperation-free survival for valve dysfunction, and survival free of AV insufficiency ≥ II were 97.3%, 100% and 91.9%, respectively. Significant reduction in the medians of the peak and mean AV gradients was maintained. Conclusions: AV reconstruction surgery showed optimal results in term of mortality, reoperation-free survival, and hemodynamic characteristics of the neo-AV.

Resumen Introducción: El reemplazo de la válvula aórtica es el tratamiento de elección para la valvulopatía aórtica severa sintomática. Recientemente, la cirugía de reconstrucción valvular aórtica (procedimiento de Ozaki) emerge como una alternativa quirúrgica con buenos resultados a mediano plazo. Métodos: Analizamos retrospectivamente 37 pacientes intervenidos de reconstrucción de válvula aórtica entre enero de 2018 y junio de 2020 en un centro de referencia nacional en Lima, Perú. La mediana de edad fue de 62 años (rango intercuartílico: 42-68). La estenosis de la válvula fue la principal indicación de cirugía (62.2%), en la mayoría de los casos por válvula bicúspide (19 pacientes, 51.4%). 22 (59.4%) pacientes presentaban otra patología con indicación de cirugía, 8 (21.6%) presentaban dilatación de la aorta ascendente con indicación de reemplazo. Resultados: La mortalidad intrahospitalaria fue de 1/38, 2.7%, por infarto de miocardio perioperatorio. Hubo una reducción significativa en las medianas del gradiente máximo (70 mmHg, IC 95% = 50.03-79.86 vs. 14 mmHg, IC 95% = 11.93-17.5, p < 0.0001) y gradiente medio (45.5 mmHg IC 95% = 30.6-49.68 vs. 7 mmHg, IC 95% = 5.93-9.6, p < 0.0001) de la válvula aórtica cuando comparamos las características basales con los resultados de los primeros 30 días. En una media de 19 (± 8.9) meses de seguimiento la sobrevida fue del 97.3%; la sobrevida libre de reoperación por disfunción valvular, 100% y la sobrevida libre de insuficiencia aórtica ≥ II, 91.9%, respectivamente. Se mantuvo una reducción significativa en las medianas de los gradientes máximo y medio de la válvula aórtica. Conclusiones: La cirugía de reconstrucción de válvula aórtica con pericardio autólogo mostró resultados óptimos en términos de mortalidad, supervivencia libre de reoperación y características hemodinámicas de la neo-válvula.

Ozaki Procedure Plus Aortic Annular Enlargement in an Extremely Narrow Aortic Annulus: A Surgical Challenge.

We report a 19-year-old woman with a history of percutaneous aortic valve (AV) balloon valvuloplasty 3 years ago. She was admitted with severe symptomatic AV stenosis with narrow aortic annulus. We decided to perform AV reconstruction with autologous pericardium. However, surgical findings revealed a very narrow AV annulus with a unicuspid valve; therefore, an AV enlargement was added.

[Right intraatrial lipoma. A case report]. / Lipoma intrauricular derecho. Reporte de un caso.

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.

Is It Possible to Place a Pacemaker Lead Through a Bileaflet Mechanical Prosthesis?

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. At 1 year of follow-up, the device shows no signs of dysfunction, and the prosthesis has moderate regurgitation.

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. Also, our primary echocardiographic endings were the diameter, area, and volume of the left atrium. We assessed these variables at 3 time periods: baseline (t0), perioperative period (t1), and extended follow-up (t2: 12 ± 3.4 months). We carried out descriptive and bivariate exploratory statistical analysis for dependent measures. Results: We included 17 patients, 70.6% of whom were women. Rheumatic mitral valve disease (76.5%) was the main etiology. We performed 14 (82.4%) mitral valve replacements and 3 repairs. Major adverse valvular-related events occurred in 1 patient (5.9%) (hemorrhagic stroke) at t1. A significant reduction in the size of the left atrium was observed: diameter (77 mm vs 48 mm, P < .001), area (75 cm2 vs 31 cm2, P < .001), and volume (332 cm3 vs 90 cm3, P < .001). Compared with t0 and t1, these echocardiographic findings remained without significant changes during t2. Conclusions: Our surgical left atrium reduction technique was associated with improved clinical functionality and reduced left atrium measures in patients with a giant left atrium undergoing mitral valve surgery.

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. We present our experience with this procedure in 3 patients with severe PV insufficiency and 1 patient with severe PV stenosis.

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. The patient was discharged on the 5th postoperative day and after 3.5 years of follow-up he remains in functional class I, without anticoagulant treatment and with mild aortic regurgitation. COCNCLUSION: The Ozaki technique can be used in patients with aortic regurgitation due to single leaflet dysfunction.

Aortic valve replacement through minithoracotomy. Results from the Peruvian experience.

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.), other concomitant cardiac procedures, redo, and emergency surgeries were excluded. We measured the variables (MAVRE, mortality, and other clinical variables) at 30 days and a mean follow-up of 12 months. Results: Fifty-four patients were studied, the median age was 69.5 years, and 65% were women. Aortic valve (AV) stenosis was the main indication for surgery (65%), and bicuspid AV represented 55.6% of cases. At 30-days, MAVRE occurred in two patients (3.7%), with no in-hospital mortality. One patient had an intraoperative ischemic stroke, and one required a permanent pacemaker. No patient underwent reoperation due to prosthesis dysfunction or endocarditis. In a mean follow-up of one year, MAVRE occurrence did not show variations with the perioperative period, most patients remained in NYHA I (90.7%) or II (7.4%) compared to the preoperative period (p<0.001). Conclusions: AV replacement through MT is a safe procedure in our center for patients under 80 years.

Objetivos: Evaluar la mortalidad, los eventos mayores relacionados con la válvula (EMRV) y otras complicaciones en el período perioperatorio y de seguimiento en pacientes con sustitución de la válvula aórtica (SVA) mediante minitoracotomía (MT). Métodos: Analizamos retrospectivamente a pacientes menores de 80 años, a quienes se les realizó SVA por MT entre enero de 2017 y diciembre de 2021 en un centro de referencia nacional en Lima, Perú. Se excluyeron pacientes sometidos a otros abordajes quirúrgicos (miniesternotomía, etc.), otros procedimientos cardíacos concomitantes, cirugías de reoperación y de emergencia. Medimos las variables (mortalidad, EMRV y otras variables clínicas) a los 30 días y un seguimiento medio de 12 meses. Resultados: Se estudiaron 54 pacientes, la mediana de edad fue de 69,5 años y el 65% fueron mujeres. La estenosis de la válvula aórtica (VA) fue la principal indicación para la cirugía (65%) y la VA bicúspide representó el 55,6% de los casos. A los 30 días, se produjeron dos EMRV (3,7%) y no hubo mortalidad intrahospitalaria. Un paciente tuvo un accidente cerebrovascular isquémico intraoperatorio y uno requirió un marcapasos permanente. Ningún paciente fue reoperado por disfunción de la prótesis o endocarditis. En un seguimiento medio de un año, la aparición de EMRV no mostró variaciones con el periodo perioperatorio; la mayoría de los pacientes permaneció en clase funcional NYHA I (90,7%) o II (7,4%) en comparación con el periodo preoperatorio (p<0,001). Conclusiones: La sustitución de la válvula aórtica mediante minitoracotomía es un procedimiento seguro en nuestro centro en pacientes<80 años.

[Prediction of significant coronary lesions by SPECT myocardial perfusion. Results from a national reference hospital in Lima-Peru]. / Predicción de lesiones coronarias significativas mediante perfusión miocárdica con SPECT. Resultados de un centro de referencia nacional en Lima-Perú.

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: . Retrospective observational study with clinical follow-up in patients undergoing SPECT and then coronary angiography. We excluded patients with myocardial infarction and percutaneous and/or surgical revascularization in the previous 6 months. Results: 105 cases were included in the study. The most commonly used SPECT protocol was pharmacological (70%). Patients with perfusion defect ≥10% of total ventricular mass (TVM) had significant coronary lesions (SCL) in 88% of cases (sensitivity 87.5% and specificity 83%). On the other hand, having ischemia ≥10% of the TVM was associated with 80% SCL (sensitivity: 72%, specificity: 65%). Clinical follow-up at 48 months evidenced that a perfusion defect ≥ 10% was predictive of major cardiovascular events (MACE) in both univariate (HR=5.3; 95%CI 1.2 - 22.2; p=0.022) and multivariate (HR= 6.1; 95%CI 1.3 - 26.9; p= 0.017) analyses. Conclusions: . Having a perfusion defect ≥10% of the MVT in the SPECT study predicted with high probability and sensitivity the existence of SCL (>80%); moreover, this group had higher MACE at follow-up.
