The frozen elephant trunk: seeking a more definitive treatment for acute type A aortic dissection.

Objectives: Conventional treatment for type A aortic dissection includes replacement of the ascending aorta with an open distal anastomosis in the hemiarch position. The frozen elephant trunk (FET) is a hybrid technique that extends the repair to the descending thoracic aorta. The goal is to improve resolution of malperfusion syndrome and to induce positive aortic remodelling and reduce the need for reintervention on the downstream aorta.

Anomalous circumflex artery: a benign variant generating a malignant potential after valve surgery.

Coronary artery anomalies are a diverse group of congenital disorders presenting with highly variable clinical manifestations. The anomalous origin of left circumflex artery from the right coronary sinus following a retro-aortic trajectory is a well-recognized anatomic variation. Despite its benign course, it can prove lethal in association with valvular surgery.

Ascending Aorta Dissection Before 5.5 cm Diameter; "It Wasn't Raining When Noah Built the Ark".

Introduction: The aim of this study was to compare mean maximum ascending aortic diameter at the time of acute aortic dissection with the current surgical threshold for elective ascending aortic operations on non-syndromic thoracic aortic aneurysms.

Material And Methods: All consecutive non-syndromic adult patients admitted for acute type A aortic dissection in a single tertiary centre were prospectively enrolled from April 2020 to March 2021. The primary endpoint was the difference between mean maximum aortic diameter at the time of dissection and the 5.

Angiographic retrograde filling of all left coronary arterial branches in a patient with chronic total occlusion of left main coronary artery.

A 81-year-old female patient was referred in our hospital with episodes of pulmonary edema and had an isolated chronic total occlusion of the left main coronary artery. Coronary angiogram showed total occlusion the left main and filling the left coronary system by collaterals from the right coronary artery.

Effects of Acute Triiodothyronine Treatment in Patients with Anterior Myocardial Infarction Undergoing Primary Angioplasty: Evidence from a Pilot Randomized Clinical Trial (ThyRepair Study).

Thyroid hormone has a differential action on healthy and ischemic heart. Triiodothyronine (T3) administration improved postischemic cardiac function while it limited apoptosis in experimentally induced ischemia. Thus, the present study investigated the potential effects of acute liothyronine (LT3) treatment in patients with anterior myocardial infarction.

Surgical Treatment of Pulmonary Embolism and Chronic Thromboembolic Pulmonary Hypertension.

Venous thromboembolism clinically presents as deep venous thrombosis or acute pulmonary embolism and is globally recognized as the third most frequent acute cardiovascular syndrome after myocardial infarction and stroke. Although pulmonary embolism does not typically cause severe pulmonary hypertension in the acute setting, thrombus organization and fibrosis can lead to stenosis or obliteration of pulmonary arteries in a minority of patients, which in turn result in severe pulmonary hypertension and right heart failure. This disease is labeled chronic thromboembolic pulmonary hypertension and can occur after a single episode or multiple ones of pulmonary embolism.

A modern approach to aortic valve insufficiency: Aortic root restoration via HAART 300 internal annuloplasty ring.

Background And Aim Of The Study: HAART 300 is an internal geometric annuloplasty ring. The safety and efficacy of this novel device in aortic valve (AV) repair in a single referral center are reported.

Methods: Twenty patients with trileaflet AV insufficiency with ascending aorta and/or aortic root enlargement were included.

External flail chest stabilization; The simple, low-cost way.

Flail chest is a life-threatening clinical entity which can be complicated by respiratory insufficiency. Paradoxical motion of a part of chest wall is the basic cause to put the blame on. Consequently, stabilization of the chest wall is occasionally of paramount importance to achieve early extubation in a patient with post-trauma respiratory insufficiency.

Perceval S valve empire: healing the Achilles' heel of sutureless aortic valves.

Aortic valve replacement is the treatment of choice concerning aortic valve disease. Excellent short- and long-term clinical results are reported. Patients referred for aortic valve replacement are getting older and older, so bioprosthetic valves play a more central role worldwide.

Congenital, acquired, or both? The only two congenitally based, acquired heart diseases.

Discrete subaortic stenosis (DSS) is a type of left ventricular outflow tract obstruction whereas double-chambered right ventricle is a form of right ventricular outflow tract obstruction. Both of these cardiac malformations share lots of similar characteristics which classify them as acquired developmental heart diseases despite their congenital anatomical substrate. Both of them are frequently associated to ventricular septal defects.

Aortocoronary saphenous vein graft aneurysm misdiagnosed as aortic arch aneurysm.

Coronary artery bypass grafting is the mainstay of revascularization worldwide. However, the most widely used saphenous vein grafts are related to a number of late sequelae. Aortocoronary saphenous vein graft aneurysms mainly diagnosed incidentally are one of these complications.

Dantrolene Induces Mitigation of Myocardial Ischemia-Reperfusion Injury by Ryanodine Receptor Inhibition.

The impairment of intracellular calcium homeostasis plays an essential role during ischemia-reperfusion injury. Calcium release from sarcoplasmic reticulum which is triggered by myocardial ischemia is mainly mediated by ryanodine receptors. Dantrolene sodium is a ryanodine receptor antagonist.

Elective replacement of the ascending aorta: is the 5.5-cm threshold appropriate? The insidious, small aorta.

Objectives: As thoracic aortic aneurysm disease continues to cause significant morbidity and mortality in the general population, the cardiovascular community continues the search for the golden threshold of elective surgical replacement of the ascending aorta.

Methods: Thoracic aortic aneurysm is a common disease, classified within the 20 most common causes of death in patients over 65 years old. Once aortic complications like dissection or rupture occur, they can prove fatal.

Debate of Percutaneous Coronary Intervention versus Coronary Artery Bypass Grafting in a Multimorbidity Patient with Complex Coronary Lesions.

Background: While complete revascularization in coronary artery disease is of high priority, the method of implementation in patients with complex coronary lesions and multiple comorbidities is not directed by published guidelines. . A 53-year-old female with a chronic total occlusion of the right coronary artery and a bifurcation lesion of the left anterior descending artery and the first diagonal branch, presented with non-ST elevation myocardial infarction.

Epicardial cardioverter defibrillator implantation due to post-fontan ventricular tachycardia.

Long-term survival of patients submitted to a Fontan procedure is reduced because of arrhythmias. Late post-Fontan ventricular tachycardia is extremely rare, but it can be fatal. Consequently, the implantation of an implantable cardioverter defibrillator may be required.

Cardioplegic storage solution: Is it the guardian of saphenous vein graft endothelium?

Introduction: Despite their suboptimal long-term patency, saphenous vein grafts are the most widely used conduits to achieve complete revascularization during coronary artery bypass grafting (CABG). Although vein storage critically impairs endothelial integrity, contradictory data concerning optimal storage solutions exist. The aim of this study is to explore any in vitro impact of cardioplegic solutions and temperature on vein grafts endothelial integrity during their storage.
