Pulmonary hypertension is an important prognostic factor in cardiac surgery associated with increased morbidity and mortality. With the aging population and the associated increase severity of illness, the prevalence of pulmonary hypertension in cardiac surgical patients will increase. In this review, the definition of pulmonary hypertension, the mechanisms and its relationship to right ventric...

introduction: coverage of bone grafts is very important in reconstructive surgery. in edentulous alveolar ridges this coverage is particularly important for supporting dental prostheses. here we present the case of a patient with a large deficient maxillary anterior region that was reconstructed with a bilateral palatal submucosal periosteal connective tissue flap: a soft tissue reserve for upp...

The most challenging objective of the clinical decision making in the management of patients with myocardial dysfunction is to choose the best option for improving myocardial function and clinical outcome. The present work aims at developing patient-specific computational models to assist cardiologists and cardiac surgeons in defining the severity and extent of disease in patients with left ven...

Bicuspid aortic valve disease is the most common congenital cardiac anomaly. The prevalence in the general population is between 0.46% and 1.37%. There is significantly high cardiac morbidity associated with bicuspid aortic valve disease, predominantly due to progressive valve dysfunction (stenosis or regurgitation) that requires surgical intervention for symptom relief or prevention of left ve...

This paper reviews the newest developments in computational cardiology. It focuses on the contribution of cardiac modeling to the development of new therapies as well as the advancement of existing ones for cardiac arrhythmias and pump dysfunction. Reviewed are cardiac modeling efforts aimed at advancing and optimizing existent therapies for cardiac disease (defibrillation, ablation of ventricu...

BackgroundThe risk of complications, including death, is substantially increased in patients with pulmonary hypertension (PH) undergoing anaesthesia for surgical procedures, especially those arterial (PAH) and chronic thromboembolic PH (CTEPH). Sedation also poses a to PH. Physiological changes tachycardia, hypotension, fluid shifts, an increase vascular resistance (PH crisis) can precipitate a...

In a community hospital setting, without academic affiliation or house staff coverage, 145 patients had elective saphenous vein graft surgery between January 1970 and January 1973. Patients with good left ventricular function, with or without associated procedures, had an operative mortality of 2.4%. The surgical mortality of patients who had associated procedures was 9.5%. The overall operativ...

A patient with preoperative pulmonary hypertension and a large left to right intracardiac shunt underwent surgical correction of a complex cardiac anomaly and required extracorporeal life support for unexplained ventricular dysfunction following the procedure. Following recovery, a fistulous connection between the right coronary artery and main pulmonary artery was demonstrated. Implications an...

Patients with heart failure represent a significantly ill cohort, and the survival of the most advanced heart failure patients is dismal with medical management alone. This cohort of advanced heart-failure patients benefits from several surgical treatments. Although several techniques for surgical ventricular restoration in the setting of left ventricular aneurysms have been described, the broa...

To the Editor:—I read the study by Fellahi JL et al. titled “Perioperative use of dobutamine in cardiac surgery and adverse cardiac outcome” with great interest. This study showed that the use of dobutamine was associated with adverse outcomes in adult cardiac surgery, and the authors concluded that these results suggest that dobutamine should only be administered when the benefit is judged to ...
