Balloon valvuloplasty in 2 juvenile alpacas with severe valvular pulmonic stenosis.

ABSTRACT: Two juvenile alpacas, 1 male and 1 female, were presented for evaluation of grade V/VI bilateral basilar systolic heart murmurs. Both animals were ultimately diagnosed with severe valvular pulmonic stenosis and a small ventricular septal defect. Transvenous balloon valvuloplasty was performed in each animal using methods described in the dog. A double balloon technique was employed in the first case, with a balloon-annulus ratio of ~1.55. For the second case, a high-pressure dilatation balloon catheter with a balloon-annulus ratio of ~1.33 was selected. Experience with both procedures indicates that balloon pulmonary valvuloplasty is technically feasible in alpacas using techniques extrapolated from those used in dogs. Furthermore, accepted criteria for procedural success were fulfilled for both alpacas, with more than a 50% reduction in the echocardiographically derived transpulmonic pressure gradient after intervention.

Balloon aortic valvuloplasty for severe aortic stenosis before urgent non-cardiac surgery.

Project description:BackgroundBalloon aortic valvuloplasty (BAV) has been proposed as a therapeutic option in patients suffering from severe aortic stenosis (SAS) who need urgent non-cardiac surgery (NCS). Whether this strategy is better than medical therapy in this very specific population is unknown.AimsWe aimed to evaluate the clinical benefit of an invasive strategy (IS) with preoperative BAV in patients with SAS requiring urgent NCS.MethodsFrom 2011 to 2019, a registry conducted in two centres included 133 patients with SAS undergoing urgent NCS, of whom 93 underwent preoperative BAV (IS) and 40 a conservative strategy (CS) without BAV. All analyses were adjusted for confounding using inverse probability of treatment weighting (IPTW) (10 clinical and anatomical variables).ResultsThe primary outcome was MACE at one-month follow-up after NCS including mortality, heart failure, and other cardiovascular outcomes. In patients managed conservatively, occurrence of MACE was 20.0% (n=8) and death was 10.0% (n=4) at 1 month. In patients undergoing BAV, the occurrence of MACE was 20.4% (n=19) and death was 5.4% (n=5) at 1 month. Among patients undergoing conservative management, all events were observed after NCS while, in patients undergoing BAV, 12.9% (n=12) had events between BAV and NCS including 3 deaths, and 7.5% (n=7) had events after NCS including 2 deaths. In IPTW propensity analyses, the incidence of the primary outcome (20.4% vs 20.0%; OR 0.93, 95% CI: 0.38-2.29) and three-month survival (89.2% vs 90.0%; IPTW-adjusted HR 0.90, 95% CI: 0.31-2.60) were similar in both groups.ConclusionsPatients with SAS managed conservatively before urgent NCS are at high risk of events. A systematic invasive strategy using BAV does not provide a significant improvement in clinical outcome.

Ultrasound-Guided Percutaneous Balloon Aortic Valvuloplasty for Aortic Stenosis.

Project description:Percutaneous balloon aortic valvuloplasty (PBAV), which is used to treat symptomatic aortic stenosis, requires ionizing radiation and contrast agent for imaging guidance. The aim of the study is to evaluate the feasibility and effectiveness of ultrasound-guided PBAV in patients with aortic stenosis. This case series included 30 patients (14 males; mean age, 61.5?±?4.5 years) with moderate/severe aortic stenosis treated with ultrasound-guided PBAV at the Ultrasound Department, Fuwai Hospital, Beijing, China, between January 2016 and July 2019. Cardiac function (New York Heart Association grade) was assessed before PBAV and 1 month after the procedure. Aortic peak jet velocity, aortic valve orifice area (AVA), mean transvalvular pressure gradient (MTPG), left ventricular end-diastolic diameter (LVDD), left ventricular ejection fraction (LVEF), and left ventricular end-systolic diameter (LVESD) were determined before and immediately after PBAV using Doppler echocardiography. Preprocedural cardiac function was grade I in 3 cases, grade II in 9 cases, grade III in 10 cases, and grade IV in 8 cases. Postprocedural cardiac function was grade I in 22 cases, grade II in 4 cases, and grade III in 4 cases, suggesting that cardiac function was improved by PBAV. Ultrasound-guided PBAV resulted in significant improvements (P < 0.05) in aortic peak jet velocity (3.68?±?0.811?m/s vs. 4.79?±?0.63?m/s), MTPG (33.77?±?13.85?mmHg vs. 54.54?±?13.81?mmHg), AVA (1.96?±?0.25?cm2 vs. 0.98?±?0.12?cm2), LVEDD (51.90?±?3.21?mm vs. 65.60?±?6.81?mm), LVEF (63.46?±?11.29% vs. 56.31?±?11.04%), and LVESD (35.50 2.62?mm vs. 45.20?±?2.42?mm). Ultrasound-guided PBAV is feasible and achieves good short-term effects in patients with aortic stenosis.

Percutaneous balloon valvuloplasty with Inoue balloon catheter technique for pulmonary valve stenosis in adolescents and adults.

Project description:BackgroundPercutaneous balloon pulmonary valvuloplasty is the procedure of choice for uncomplicated severe or symptomatic pulmonary stenosis. The present study describes our experience in balloon pulmonary valvuloplasty using the Inoue balloon catheter in adolescent and adult patients.AimsTo assess the immediate and mid-term outcomes of percutaneous balloon valvuloplasty with Inoue balloon catheter in adolescent and adult patients.Methods and resultsBetween June 2010 and July 2015, we performed percutaneous balloon pulmonary valvuloplasty with Inoue balloon catheter in 32 patients (59.37% females) aged 8 to 54 years (mean 23.6±11.5). Following the procedure, the mean right ventricular systolic pressure and the pulmonary valvular peak-to-peak systolic gradient decreased from (121.6±42.4 to 61.19±24.5mmHg, p=0.001) and (100.9±43.3 to 36.4±22.5mmHg, p=0.001), respectively. Twenty patients (Group A) showed immediate optimal results with post-procedure peak systolic gradient <36mmHg while 12 patients (Group B) had suboptimal results. An increase in pulmonary regurgitation by one grade was detected in 17 patients (53.2%). Twenty-three patients available for follow-up (mean duration, 2.75 years [range 0.25-5 years]) had a mean residual peak gradient of 23.6±2.51mmHg on Doppler echocardiography with attenuation of reactive RVOT stenosis in all Group B patients. There was no further increase in grade of pulmonary regurgitation or restenosis on mid-term follow-up.ConclusionPercutaneous Inoue balloon technique is an attractive alternative with excellent mid-term results for adolescents and adults with isolated pulmonary stenosis.

New Pulmonary Valvuloplasty Technique by Use of an Hourglass-Shaped Balloon in 3 Adults with Severe Pulmonary Valve Stenosis.

Project description:Percutaneous balloon pulmonary valvuloplasty is the preferred therapy for pulmonary valve stenosis. However, the designs of the cylindrical balloons historically used for valvuloplasty have limitations, especially in patients who have large pulmonary annular diameters. The hourglass-shaped V8 Aortic Valvuloplasty Balloon may prove to be an effective alternative. The balloon has 2 large bulbous segments that are separated by a narrowed waist. The geometric shape is maintained throughout inflation, improving fixation and enabling broader leaflet opening. We present our first experience with the V8 balloon in 3 adults who had severe, symptomatic pulmonary valve stenosis. In addition to describing their cases, we detail our sizing technique for pulmonary valvuloplasty with the V8 balloon. Our successful results suggest that the V8 balloon is efficient and safe for balloon pulmonary valvuloplasty in adults with severe pulmonary valve stenosis.

Balloon Valvuloplasty of Tricuspid Stenosis: A Retrospective Study of 5 Labrador Retriever Dogs.

Project description:BackgroundThere are limited reports of severe tricuspid valve stenosis in dogs and limited data regarding treatment and outcome.ObjectiveTo evaluate clinical signs, echocardiographic features, and outcome of balloon valvuloplasty (BV) in dogs with severe tricuspid valve stenosis (TVS) in which BV was attempted.AnimalsFive client-owned dogs with severe TVS.MethodsRecords were retrospectively reviewed and data collected regarding signalment, clinical signs, diagnostic findings, procedures, and outcome.ResultsAll dogs were Labrador Retrievers. Presenting complaints included episodic weakness/syncope (4/5), abdominal distension (4/5), lethargy (2/5), and exercise intolerance (2/5). The median and range of measurements before BV were as follows: TV mean velocity 1.5 m/s (range 1.4-1.7 m/s); velocity-time integral (VTI) 79.8 cm (42.4-99.1 cm); and TV maximum velocity 2.9 m/s (2.3-3.2 m/s). Measurements (available for 3 of 5 dogs) after BV were as follows: TV mean velocity 1.15 m/s (0.9-1.4 m/s); VTI 44.95 cm (41.4-54.8 cm); and TV maximum velocity 1.15 m/s (1.9-2.3 m/s). The procedure was attempted in all dogs and completed in 4/5 dogs. The largest balloon diameter ranged from 15 mm to 25 mm, and length ranged from 4 cm to 5 cm. Right atrial pressure decreased in 4/5 dogs. All but 1 dog had clinical improvement after BV, but recurrence of clinical signs occurred (2/5). Tricuspid regurgitation worsened in 1 dog culminating in right heart failure and euthanasia.Conclusions and clinical importanceBV can be an effective treatment; however, clinical signs can recur. Right heart failure due to worsened TR is a potential complication in dogs with pre-existing moderate-to-severe TR.

Balloon aortic valvuloplasty as a palliative treatment in patients with severe aortic stenosis and limited life expectancy: a single center experience.

Project description:Whether balloon aortic valvuloplasty (BAV) may provide an effective palliation in symptomatic high-risk patients is uncertain. Therefore, we aimed to evaluate outcomes in symptomatic high-risk patients with severe aortic stenosis (AS), who underwent BAV. All-cause mortality and length of hospitalization for heart failure (HF) up to death or to 1-year follow up were collected after BAV. One hundred thirty-two (132) patients (62% women), mean age 85±7 years, underwent BAV with a substantial reduction of the peak-to-peak aortic gradient from 53±21 to 29±15 mmHg (p<0.001). The median of days of HF hospitalization prior to BAV was 9 (0-19), and decreased after BAV to 0 (0-9), p<0.001. During 1-year follow-up patients with untreated CAD (85, 64%) had a higher mortality compared to patients with insignificant/treated CAD (47, 36%): 1-year survival: 45±7% vs. 66± 7%; p=0.02. After adjustment for STS risk score and severity of residual AS, patients with untreated CAD remained at higher risk of mortality (adjusted HR 1.74 [1.01-2.91]; p=0.04). Thus, in this series of symptomatic high-risk patients, BAV was associated with a significant reduction in aortic valve gradient and hospitalization time for HF post-BAV. In patients with significant CAD, percutaneous intervention might be considered in order to improve survival.
