Objective: To report successful surgical treatment of double chambered right ventricle (DCRV) in a cat.
Study Design: Clinical report.
Animals: Cat with DCRV.
Methods: DCRV was diagnosed in a 5-month-old male Maine Coon cat using echocardiography and angiocardiography. At 2 years, despite medical therapy, chylothorax developed. A section of the right ventricular free wall that spanned the fibromuscular obstruction was excised under total venous inflow occlusion (TVIO) using the incised pericardial patch technique.
Results: Short-term recovery was complicated by return of chylothorax but this resolved after thoracocentesis and diuretic therapy. Three years after surgery, the cat is free of clinical signs and no longer on any medical therapy.
Conclusions: Partial right ventriculectomy can be performed under TVIO through an incised pericardial patch.
Clinical Relevance: DCRV in cat can be successfully treated by partial right ventriculectomy performed under TVIO through an incised pericardial patch.

The combination of severe fetal mitral regurgitation diagnosed in utero, aortic stenosis, left ventricular dilatation, and dysfunction is associated with extremely poor prognosis. We report a neonate who underwent Norwood operation and left ventricular exclusion using partial left ventriculotomy and Alfieri mitral valve stitch. Left ventricular exclusion eliminated right ventricular compression and allowed survival and progression to subsequent second-stage palliation.

Over time, various surgical treatment strategies have evolved to manage advanced heart failure (HF). Scientific and technological breakthroughs through the last 50 years have put forward various surgical alternatives to patients with advanced HF encompassing surgical ventricular restoration to surgical gene therapy and stem cell replacement of the diseased ventricles. Organ-saving surgical options which used to be promising included dynamic cardiomyoplasty, partial resection of ventricle and cardiac wrapping with Acorn CorCap cardiac support device.

Introduction: The number of cases for which the Batista procedure is indicated is small, but some patients with appropriate indication can achieve good therapeutic results.
Objective: To avoid incorrect left ventricular incision and obtain good surgical results in patients with dilated cardiomyopathy suitable for partial left ventriculectomy, we employed intraoperative direct echocardiography to determine the exact extent and position of the myocardial incision, even for surgeons who are not very experienced with the Batista procedure.
Methods: A 72-year-old man with dilated cardiomyopathy underwent the Batista procedure with the aid of epicardial echocardiography to confirm the location of both the papillary muscles and the diseased myocardium.

Congestive heart failure (CHF) is one of the major causes of death and occurs in more than 15,000,000 patients worldwide. The incidence is expected to increase in parallel with the aging population. Most current therapies for CHF are medications, and biventricular pacing implantation as appropriated by cardiologists, or surgical interventions.
