Left bundle branch block (LBBB) is common in heart failure patients, and could induce dyssynchrony of ventricular contraction, deterioration of cardiac function, and increased mortality. Cardiac resynchronization therapy (CRT) with biventricular pacing reduces ventricular dyssynchrony, heart failure hospitalization, and all-cause mortality in heart failure patients with LBBB. However, there are approximately 30% nonresponders and 10% of patients remain untreated owing to an unsuitable coronary sinus vein.

In such cases, hybrid procedures may provide alternatives. Because the most commonly used median sternotomy is unsuitable for chronic trials in large animals, we evaluated several hybrid approaches for pulmonary valve replacement in a swine model.

Background: The complexity of ventricular septal defects in early infancy led to development of new mini-invasive techniques based on collaboration of cardiac surgeons with interventional cardiologists, called hybrid procedures. Hybrid therapies aim to combine the advantages of surgical and interventional techniques in an effort to reduce the invasiveness. The aim of this study was to present our approach with mVSD patients and initial results in the development of a mini-invasive hybrid procedure in the Gdansk Hybrid Heartlink Programme (GHHP) at the Department of Pediatric Cardiac Surgery, Pomeranian Centre of Traumatology in Gdansk, Poland.

Objectives: Right ventricular (RV) dysfunction is a significant cause of morbidity and mortality after surgical correction of tetralogy of Fallot (TOF). Transatrial/transpulmonary repair avoids a ventriculotomy (in contrast to the transventricular approach) emphasizing maximal preservation of RV structure and function. We have adopted this technique as less traumatic for the right ventricle.

There are a number of surgical alternatives to repeat artery bypass grafting, which is the primary treatment for recurrent severe myocardial ischemia. In patients with endstage coronary artery disease unsuitable for repeat bypass procedures, orthotopic heart transplantation is now well established. However, the increasing donor shortage limits this option to relatively few patients, a fact well documented by longer waiting lists despite less stringent donor criteria.
