Immediate Use of Impella CP for High-Risk Percutaneous Coronary Intervention After Repair of Thrombosed Aortic Coarctation.

Aortic coarctation represents up to 7% of congenital heart diseases and is associated with hypertension and coronary artery disease, which continues to be the leading cause of death even after successful surgical repair. However, there is limited knowledge of managing both conditions, especially in the setting of an acute coronary syndrome. We herein present the case of a 53-year-old man with a history of hypertension who initially presented with an ST-elevation myocardial infarction successfully treated with thrombolysis and hemodynamic compromise.

Selective embolization with autologous fat to treat massive bleeding secondary to percutaneous renal biopsy.

Bleeding following a percutaneous renal biopsy is a complication that can be life-threatening. Embolization of the bleeding artery is a procedure that can limit the damage; however, embolization devices can be costly or not immediately available. This is why we present the case of a 25-year-old man with a history of multiple thromboses who underwent a renal biopsy due to suspected systemic lupus erythematosus.

Intracardiac echocardiography-guided biopsies for right-sided intracardiac tumors: An optimized diagnostic algorithm and case illustrations.

Intracardiac tumors, though uncommon, necessitate a swift and accurate diagnosis for personalized treatment and prognosis estimation. While multi-modality imaging often determines the etiology of these cardiac masses, histological confirmation remains essential for definitive diagnosis and its specific treatment. Since cardiac tumors are often found in high-risk locations (ventricular free wall or atria), precision biopsy is paramount.

[Treatment of cardiogenic shock due to right ventricular involvement].

The right ventricle is susceptible to changes in preload, afterload, and contractility. The answer is its dilation with dysfunction/acute failure; filling is limited to the left ventricle and cardiac output. Systemic venous congestion is retrograde to the right heart, it is involved in the genesis of cardiogenic shock due to right ventricle involvement.

[Anatomy-physiology considerations for cardiogenic shock with right ventricular involvement].

Since the discovery of right ventricular infarction, interest in the characteristics of the right ventricle has been increasing. Right ventricular function is now known to be a predictor of mortality in different settings. The right ventricle is a low-pressure, high-compliance, high-volume chamber.

Assessing the venous system: Correlation of mean systemic filling pressure with the venous excess ultrasound grading system in cardiac surgery.

Background: Evaluation of the venous system has long been underestimated as an important component of the circulatory system. As systemic venous pressure increases, the perfusion pressure to the tissues is compromised. During initial resuscitation in cardiac surgery, excessive fluid administration is associated with increased morbidity and mortality.

Left atrial veno-arterial extracorporeal membrane oxygenation in post-myocardial infarction ventricular septal defect with cardiogenic shock: a case report.

Background: Ventricular septal defect (VSD) complicating acute myocardial infarction (MI) represents a life-threatening condition and has a mortality of >90% if left untreated.

Case Summary: A 53-year-old man with a prior medical history of diabetes and hypertension presented with cardiogenic shock secondary to VSD as a mechanical complication of non-reperfused inferior MI.

Discussion: The choice of mechanical support can be difficult in this type of patient.

Usefulness of the velocity-time integral of the left ventricular outflow tract variability index to predict fluid responsiveness in patients undergoing cardiac surgery.

Background: Haemodynamic monitoring of patients after cardiac surgery using echocardiographic evaluation of fluid responsiveness is both challenging and increasingly popular. We evaluated fluid responsiveness in the first hours after surgery by determining the variability of the velocity-time integral of the left ventricular outflow tract (VTI-LVOT).

Methods: We conducted a cross-sectional study of 50 consecutive adult patients who underwent cardiac surgery and in whom it was possible to obtain VTI-LVOT measurements.

Left circumflex artery injury occurring during mitral valve surgery treated successfully with percutaneous intervention in a high surgical and bleeding risk patient.

Unlabelled: Perioperative myocardial infarction is a complication of cardiac surgery, and the cause can be multifactorial. Injury of the left circumflex coronary artery has been described, particularly after mitral valve replacement. We present the case of a 72-year-old woman who underwent mitral valve replacement but developed a lesion in the proximal circumflex coronary artery related to partial mechanical kinking caused by a suture.

Cardiogenic Shock Among Patients with and without Acute Myocardial Infarction in a Latin American Country: A Single-Institution Study.

Background: Latin America has limited information about the full spectrum cardiogenic shock (CS) and its hospital outcome. This study sought to examine the temporal trends, clinical features and outcomes of patients with CS in a coronary care unit of single Mexican institution.

Methods: This was a retrospective study of consecutive patients hospitalized with CS in a Mexican teaching hospital between 2006-2019.

Critical care ultrasonography during COVID-19 pandemic: The ORACLE protocol.

Background: Coronavirus disease 2019 (COVID-19) is characterized by severe lung involvement and hemodynamic alterations. Critical care ultrasonography is vital because it provides real time information for diagnosis and treatment. Suggested protocols for image acquisition and measurements have not yet been evaluated.

Bilateral spontaneous pneumothorax in SARS-CoV-2 infection: A very rare, life-threatening complication.

In the coronavirus disease 2019 (COVID-19) era, the presence of acute respiratory failure is generally associated with acute respiratory distress syndrome; however, it is essential to consider other differential diagnoses that require different, and urgent, therapeutic approaches. Herein we describe a COVID-19 case complicated with bilateral spontaneous pneumothorax. A previously healthy 45-year-old man was admitted to our emergency department with sudden-onset chest pain and progressive shortness of breath 17 days after diagnosis with uncomplicated COVID-19 infection.

Histological and Mechanical Behavior of INC 01 and 02 Bare Metal Stents Against a Commercial Stent: A Preclinical Study in a Porcine Model.

Background: PCI is an expensive procedure in our population and it implies a huge cost for the institutions and National Health Service.

Aim Of The Study: The main objective was to evaluate the technical and biological success of two stents designed in Mexico.

Methods: Ten York pigs, 4-6 months of age, underwent implantation of the bare metal INC-01 (10 stents) and INC-02 (6 stents) coronary stent in addition to a conventional commercial stent (10 stents).

Normal function of a 43-year-old Braunwald Cutter heart valve.

We present the case of a 72-year-old woman diagnosed with rheumatic fever at the age of 6. In 1972, she was diagnosed with mitral valve insufficiency and mitral valve stenosis, then in 1974, a decision was made to perform mitral valve replacement surgery with a 32-mm Braunwald-Cutter ball cage prosthesis. An echocardiogram performed in 2014 revealed normal biventricular systolic function, mechanical prosthesis in mitral position with maximum speed of 1.
