“…In this case, a De Vega rather than band annuloplasty was selected because the De Vega approach shortens the operation time and obtains good outcomes ( 8 ). De Vega annuloplasty has been shown to be effective and durable in the treatment of mitral regurgitation in dogs and has been performed in many cases ( 17 , 18 ).…”

“…However, there are no guidelines for the treatment of TR in veterinary medicine. Furthermore, there are no reports of surgical treatment for acquired TR in dogs, although there are reports of surgical treatment for tricuspid dysplasia ( 6 – 8 ). To the best of our knowledge, this is the first report of a successful surgical tricuspid annuloplasty (TAP) performed in a dog with TR acquired secondarily to PH.…”

An 11-year-old, 12.3-kg, female Miniature Dachshund was presented to our institution with ascites of unknown etiology. The dog had been administered moxidectin for 3 years to treat a heartworm infection. Thoracic radiographs showed enlargement of the right heart. Echocardiography revealed right atrial and ventricular dilatation as well as flattening of the interventricular septum. Heartworm was identified in the main pulmonary artery, which was dilated. Tricuspid regurgitation (TR) was observed using color Doppler ultrasonography, and 2.5 L of ascites were removed. The dog was diagnosed with pulmonary hypertension, severe TR, and right-sided congestive heart failure. Except at the initial site, heartworm was not detected using echocardiography, and the antigen test was negative. However, pharmacological treatment did not improve the right-sided congestive heart failure. Instead, De Vega tricuspid annuloplasty (TAP) was performed on the beating heart under cardiopulmonary bypass with the owner's consent. Sutures terminated between the two commissures in the middle of the annulus and were secured using another pledget. Annular reduction was performed by tying down the plication suture while the cylindrical sizer was inserted into the tricuspid valve orifice. The size of the cylindrical sizer was 16 mm, which was set based on the height and width of the septal leaflet. A 6-month follow-up showed a reduction of TR and right-sided volume overload with no evidence of ascites retention/recurrence or any other complication. Our findings indicate that TAP may be a valid treatment option for dogs with right-sided congestive heart failure caused by secondary TR.

“…Dogs were positioned in lateral recumbency for CPB and surgery. Prior to cannulation for CPB, heparin sulfate (300 units/kg, IV) was administered to achieve complete anticoagulation, defined as an activated clotting time over 480 s ( 14 ). Antifibrinolytic therapy with epsilon amino-caproic acid (50 mg/kg IV over 30 min) was administered as a bolus before initiation of CPB and maintained as a constant rate infusion (10 mg/kg/h) during CPB.…”

IntroductionTo evaluate microcirculation and endothelial glycocalyx (eGC) variables using sidestream darkfield (SDF) videomicroscopy in canine cardiopulmonary bypass (CPB).MethodsDogs undergoing CPB for surgical correction of naturally-occurring cardiac disease were prospectively included. Variables collected included patient demographics, underlying cardiac disease, red blood cell flow (Flow), 4-25 μm vessel density (Density), absolute capillary blood volume (CBVabs), relative capillary blood volume (CBVrel) and eGC width assessed by perfused boundary region (PBR). Anesthetized healthy dogs were used as control. Microcirculation and eGC variables were compared at baseline under anesthesia (T0), on CPB prior to cross clamping (T1), after cross clamp removal following surgical correction (T2) and at surgical closure (T3).ResultsTwelve dogs were enrolled, including 10 with a complete dataset. Median Flow was 233.9, 79.9, 164.3, and 136.1 μm/s at T0, T1, T2, and T3, respectively, (p = 1.00). Median Density was 173.3, 118.4, 121.0 and 155.4 mm/mm2 at T0, T1, T2, and T3, respectively, (p = 1.00). Median CBVabs decreased over time: 7.4, 6.6, 4.8 and 4.7 103μm3 at T0, T1, T2, and T3, respectively, (p < 0.01). Median CBVrel increased over time: 1.1, 1.5,1.1, and 1.3 103μm3 at T0, T1, T2, and T3, respectively, (p < 0.001). Median PBR increased over time: 1.8, 2.1, 2.4, 2.1 μm at T0, T1, T2, and T3, respectively, (p < 0.001). Compared to control dogs (n = 8), CPB dogs had lower CBVabs at T0.ConclusionAlterations in eGC thickness and microvascular occur in dogs undergoing CPB for naturally-occurring cardiac disease.

“…A similar approach was used for the tricuspid valve repair in a recent publication. 15 The septal leaflet was released from the short primary and secondary chordae tendinae by sharp dissection. The septal leaflet was resuspended using three artificial chords of ePTFE suture (CV5 Gore-Tex Suture, W. L. Gore & Associates, Inc.).…”
